I'm migrating a JEE / JBOSS project to Quarkus.
In this project I've got a DAO which is shared by many EJB's (SOAP services, REST services). The DAO defines also the entities and the persistence.xml like this:
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="broGmw">
<jta-data-source>java:jboss/datasources/BroDS</jta-data-source>
<class>x</class>
<class>y</class>
<!--> many more <-->
<properties>
<property name="hibernate.dialect" value="org.hibernate.spatial.dialect.oracle.OracleSpatial10gDialect" />
<property name="hibernate.show_sql" value="false" />
</properties>
</persistence-unit>
</persistence>
Now, I know that the jta datasource is not yet supported in quarkus.
I don't want to redefine the same persistence.xml in each endpoint EJB in my JEE project. Also, removing it from the DAO library does not feel logical, since persistence.xml logically belongs to the DAO.
Quarkus however, does not tolerate the jta-data-source. So I want to redefine only the data-source in the application properties, leaving the persistence.xml in the DAO (library).
quarkus.datasource.broDs.db-kind=other
quarkus.datasource.broDs.username=xxx
quarkus.datasource.broDs.password=yyy
quarkus.datasource.broDs.jdbc.url=myUrl
quarkus.datasource.broDs.jdbc.driver=${QUARKUS-BRO-DATASOURCE-DRIVER:oracle.jdbc.OracleDriver}
quarkus.hibernate-orm.broGmw.dialect=${QUARKUS-ORM-DIALECT:org.hibernate.spatial.dialect.oracle.OracleSpatial10gDialect}
quarkus.hibernate-orm.broGmw.log.sql=${QUARKUS-ORM-LOG-SQL:false}
#quarkus.hibernate-orm.broGmw.packages=... (here's where I want the content of my persistence.xml read)
quarkus.hibernate-orm.broGmw.datasource=broDs
However, Quarkus ignores this as soon when it finds the persistence.xml

How can I realize this?
Filtering the persistence.xml from the dependencies is perhaps also an option. I know that this is possible in the next version of Quarkus, but perhaps there's a generic mechanism to filter files (classes, xml) from the dependencies to make Quarkus ignore them.
The SKIP_PARSE_PERSISTENCE_XML property has to be passed when you run your Quarkus application, not when you build it.
Passing it to the quarkus-maven-plugin won't help.
It requires to be added to the maven build as -D property, configured in the IDE and in possible build scripts in CI/CD.

We have a custom keyloak user storage provide to use our proprietary user database for authentication.
This works perfectly fine with the WildFly based Keycloak. Since Keycloak will drop WildFly support in june 2022 according to their release notes, I am currently trying to get it running in the new, Quarkus based Keycloak distribution.
First I had to remove all dependencies provided by Quarkus since those lead to class loader issues. But now I am stuck with this error when I try to start Keycloak with the command ./kc.sh start-dev --log-level=ERROR:
Updating the configuration and installing your custom providers, if any. Please wait.
ERROR: Unexpected error when starting the server in (development) mode
ERROR: Failed to start quarkus
ERROR: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]
ERROR: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
For more details run the same command passing the '--verbose' option. Also you can use '--help' to see the details about the usage of the particular command.
And 'hibernate.dialect' is set in persistence.xml and configuring a persistance unit in persistence.xml should be supported according to quarkus documentation :
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
version="2.1">
<persistence-unit name="example-pu" transaction-type="JTA">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<class>com.example.keycloak.provider.db.entity.Benutzer</class>
<class>com.example.keycloak.provider.db.entity.BenutzerWithSource</class>
<class>com.example.keycloak.provider.db.entity.Rolle</class>
<class>com.example.keycloak.provider.db.entity.Parameter</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/>
</properties>
</persistence-unit>
</persistence>
Configuring the dialect in an application.properties (according to https://quarkus.io/guides/hibernate-orm#multiple-persistence-units) file in the delivery didn't change the behavior as well:
quarkus.hibernate-orm."example-pu".hibernate-dialect=org.hibernate.dialect.OracleDialect
What am I missing?
Additional Persistence Units are not supported in Keycloak 17.0.0 with Quarkus.
This should be fixed in Keycloak 18.0.0: https://github.com/keycloak/keycloak/pull/10581.
I have source code for a framework, let's call it my-framework. It provides various packages, including com.not_telling.framework.db.
I have a pom.xml file for this framework:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.not_telling</groupId>
<artifactId>my-famework</artifactId>
<packaging>jar</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>my-framework Maven Library</name>
<url>http://maven.apache.org</url>
<!-- more things here... -->
</project>
I can compile this and install it to my local repository cache, using this command:
mvn install
End of the install log:
[INFO] Installing C:\Users\MyUserName\my-framework\backend\target\my-framework.jar to C:\Users\MyUserName\.m2\repository\com\not_telling\my-famework\0.0.1-SNAPSHOT\my-famework-0.0.1-SNAPSHOT.jar
[INFO] Installing C:\Users\MyUserName\my-framework\backend\pom.xml to C:\Users\MyUserName\.m2\repository\com\not_telling\my-famework\0.0.1-SNAPSHOT\my-famework-0.0.1-SNAPSHOT.pom
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
Then I have another project, that tries to use this as a dependency:
<dependency>
<groupId>com.not_telling</groupId>
<artifactId>my-famework</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
The compilation phase of this project fails with this message:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project my-project: Compilation failure: Compilation failure:
[ERROR] /C:/Users/MyUserName/workspace/my-project/backend/src/main/java/com/not_telling/some_example.java:[13,17] package com.not_telling.framework.db does not exist
Why is that? Maybe because the jar is in the repository cache, but not in a local repository?
This question is a follow up of absolute maven pomderived entry added to classpath - I realized that instead of doing magic with relative source directory references, I need to make a separate module, but I'm facing this problem.
It was bleeding from numerous wounds. These needed to be fixed:
move source files from under src/ to under src/main/java, in both the framework and the application project
change the group and the artifact id to match the package name E.g. for a package that is named "com.not_telling.framework" I had to use groupId=com.not_telling and name=framework.
The dependency scope was wrong in the application's pom file. I had to remove test
Now it works from command line I can do "mvn install" for the framework, and then "mvn package" for the applications.
The only problem left is that the application cannot be compiled from eclipse, I had to remove all linked source folders / build paths in the application project to the framework.
I'm trying to make a web script in groovy and run that web script on Alfresco. But, i don't know how to. I read tutorials but I haven't come to any conclusion...
Anyone knows all steps to run a web script in groovy ? Which files I need?
My idea is to make a integration of one application groovy on Alfresco.
For example, i'm trying to test one of this web scripts: https://github.com/pmonks/alfresco-groovy-webscripts
But i got the error :
$ mvn clean package

I try too the web scripts already in Alfresco examples, but i got error, for example:
The Web Script /alfresco/s/default/surfbug has responded with a status of 500 - Internal Error.
This looks like strictly a maven problem to me. The exception states that Unable to download the artifact from any repository. This means that you've got a dependency on something that can't be found in either your local repository or any of the default or configured remote repository.
The missing dependency is stated as org.alfresco.extension:alfresco-groovy-webscripts-parent:pom:1.3. To get this to work, this artifact needs to be in your local repository. I couldn't find any reference to this in the common remote repositories, so it might be something you need to build from source.
The link you provided in your question is for a github project with the following code in its pom.xml file:
<groupId>org.alfresco.extension</groupId>
<artifactId>alfresco-groovy-webscripts-parent</artifactId>
<packaging>pom</packaging>
<version>1.4-SNAPSHOT</version>
Notice that the groupId and artifactId match your missing dependency, but the version is different. If you've installed this sample, using mvn install, then version 1.4-SNAPSHOT of this dependency should already be in your local repository. You could search your pom files for the dependency on alfresco-groovy-webscripts-parent v1.3, and change it to 1.4-SNAPSHOT and try again.
I am using hyperjaxb to generate Java classes from an xsd file. How can I configure it to generate hibernate annotations, and to trigger hbm2ddl to create a MySQL database with tables for the generated classes?
I downloaded the purchase order sample for hibernate from this link, then navigated to the target directory in cmd.exe and ran mvn clean install, but the resulting folders did not contain any java classes, and this also did not contain any hibernate/MySQL. I would like to get a working example that creates everything from a downloaded xsd file so that I can just plug my own xsd file into the code and have all the java/hibernate/mysql be autogenerated. That way I can spend my time tweaking my xsd file so that the resulting java/hibernate/MySQL is what I need it to be.
A code example or step by step instructions would be really helpful. I am using eclipse.
**EDIT: **
The answer to this question came after posting a few other questions. To find the complete answer to this question, you will need to review the answers to those other questions, in particular, the one at this link.
UPDATE
Finally it appeared that the OP was looking for generated classes in the root directory of the project insteadof target\generated-source\xjc, despite the tutorial clearly states where to look:
If you browse the target/generated-sources/xjc directory, you'll find
few generated java files, for instance PurchaseOrderType.java.
I don't understand it when you say that nothing is generated. I've just rechecked it, everything works fine.

Full mvn clean install -X log is here.
So I hope you see, it works perfectly. Please post you mvn clean install -X, maybe you do something wrong.
Now, concerning your question, here's the MySQL example:
https://github.com/highsource/hyperjaxb3/tree/master/ejb/tests/po-mysql
This project includes a snippet of hbm2ddl generation:
https://github.com/highsource/hyperjaxb3/tree/master/ejb/tests/issues
The hbm2ddl is commented out for some reason, not sure if it works, but it should give the direction.
This is a part of another answer which answers the MySQL part. I add this here for future reference in an attempt to close this question.
So from now on I assume that the PO tutorial worked fine: the code was generated, roundtrip test ran with the HSQLDB database etc.
Now we'll address two questions:
How to switch to MySQL?
How to generate database schema with hbm2ddl?
Let's get started.
Switching to MySQL
First of all, you have to replace HSQLDB with MySQL in the pom.xml. Remove this:
<dependency>
<groupId>hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<version>1.8.0.7</version>
<scope>test</scope>
</dependency>
And add this:

Next, edit src/test/resources/persistence.properties. Replace this:
hibernate.dialect=org.hibernate.dialect.HSQLDialect
hibernate.connection.driver_class=org.hsqldb.jdbcDriver
hibernate.connection.username=sa
hibernate.connection.password=
hibernate.connection.url=jdbc:hsqldb:target/test-database/database
hibernate.hbm2ddl.auto=create-drop
hibernate.cache.provider_class=org.hibernate.cache.HashtableCacheProvider
hibernate.jdbc.batch_size=0
With this:
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.connection.driver_class=com.mysql.jdbc.Driver
hibernate.connection.username=...
hibernate.connection.password=...
hibernate.connection.url=jdbc:mysql://localhost/hj3
hibernate.hbm2ddl.auto=create-drop
hibernate.cache.provider_class=org.hibernate.cache.HashtableCacheProvider
hibernate.jdbc.batch_size=0
I personally don't have a MySQL database at hand at the moment, so I can't really test the roundtrip. Therefore I'll comment out
<!--roundtripTestClassName>RoundtripTest</roundtripTestClassName-->
in pom.xml.
If you have a database at hand, just configure the right URL/username/password in the mentioned persistence.properties file.
At this point your Maven project is reconfigured to use MySQL. If the roundtrip test is not commented out and the database is available, the roundrip test should run with the DB, i.e. create the schema, import the sample XML, read it back and compare alpha and omega.
So now we have the tutorial on MySQL and can move on.
Generating the database schema
This was a tricky part to figure out.
In order to generate the database schema in a file, you have to use the hbm2ddl tool. There are Maven plugins for that, in case of Hibernate 3 it seemed that the Codehaus plugin is the leading one. Finally, I have figured out the following configuration. You have to add the following plugin to your pom.xml (project/build/plugins):
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>3.0</version>
<executions>
<execution>
<id>generate-schema</id>
<phase>compile</phase>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
<configuration>
<hibernatetool>
<classpath>
<path location="${project.build.directory}/classes" />
</classpath>
<jpaconfiguration persistenceunit="org.jvnet.hyperjaxb3.ejb.tests.pocustomized" propertyfile="src/test/resources/persistence.properties"/>
<hbm2ddl export="false" create="true" update="false" format="true" outputfilename="schema.ddl" />
</hibernatetool>
</configuration>
<dependencies>
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.0.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.6.5.Final</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.0.5</version>
</dependency>
</dependencies>
</plugin>
Few things are important:
Hyperjaxb3 generates JPA annotations, so you have to use jpaconfiguration.
Therefore the hibernate3-maven-plugin must be executed in the compile phase (you need classes to read annotations from so they have to be compiled at that moment).
You have to include the compiled classes (${project.build.directory}/classes) to the hibernatetool's classpath so that it can discover classes and read annotations.
You have to let the hibernatetool know where you find your Hibernate properties (propertyfile="src/test/resources/persistence.properties").
Finally you have to let it know, which persistence unit you want to process (persistenceunit="org.jvnet.hyperjaxb3.ejb.tests.pocustomized"). Take a look at target/generated-sources/xjc/META-INF/persistence.xml.
Finally, add all the required dependencies.
Finally you arrive at the configuration I posted above. At this point the build should also generate the database schema in target/sql/hibernate3/schema.ddl.
I am trying to get a basic Seam 3 webapplication to work and use the jboss-javaee6-webapp to achieve this goal. Using the manual at http://seamframework.org/Documentation/CDIQuickstartForMavenUsers.
However, I am running into some problems which I haven't been able to solve for days. I have basically no experience in JavaEE so the solution is probably really easy.
What I've done? I've simply generated a new maven project based on the supplied archetype and didn't change anything about it. I've installed Eclipse Helios including JBoss Tools and downloaded JBoss 6.0.0 and got Eclipse to deploy the application to the server succesfully.
While deploying, an exception occurs in the example code. To be specific the following exceptions occurs:

I've searched for a solution for this exact exception but I could barely find anything about it. This probably means that I've overlooked something very simple. So I've analysed the exception and found the following:
The exception message is from the example code (SeedDataImporter.java:61)
The exception itself (NullPointer) is thrown somewhere in the weld code
The problem seems to be purely persistence related (it can't find the PersistenceContext?)
Since the problem is persistence related, I've tried to change the persistence.xml however this didn't pay out. I think the problem is within the JDNI/Persistence.xml/Server config domain, however I can't be sure.
Can anybody point me in the right direction?
persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</persistence-unit>
Edit:
When I try to deploy the unchanged application to GlassFish 3.1 within Eclipse I get the following error:
cannot Deploy seam3-example
Deployment Error for module: seam3-example: Error occurred during deployment: Exception while loading the app : javax.ejb.CreateException: Initialization failed for Singleton SeedDataImporter. Please see server.log for more details.
Cannot create tables for application seam3-example. The expected DDL file seam3-example_primary_createDDL.jdbc is not available.
Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.2.0.v20110202-r8913): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Error in allocating a connection. Cause: Connection could not be allocated because: java.net.ConnectException : Error connecting to server localhost on port 1527 with message Connection refused.
I think it is a persistance.xml problem because you have:
<jta-data-source>jdbc/__default</jta-data-source>
and this is default for Glassfish AS
Try this:
<jta-data-source>java:/DefaultDS</jta-data-source>
This is default for JBoss
Do you run JBoss AS in default domain?
If you check the persistence.xml file generated by the archetype, you'll see this comment:
<!-- A matching data source is added to JBoss AS by deploying the project file default-ds.xml -->
<jta-data-source>jdbc/__default</jta-data-source>
Inside resources-jbossas there's a default-ds.xml file that you should deploy to JBoss in order to be able to use the app without any code changes.
At least on the command line I can start the example doing this:
Download and install the latest jboss 6 to
mvn archetype:generate -DarchetypeArtifactId=jboss-javaee6-webapp -DarchetypeGroupId=org.jboss.weld.archetypes -DarchetypeVersion=1.0.1.CR1 -DarchetypeRepository=central -DgroupId=com.example -DartifactId=jee-example -Dversion=0.0.1-SNAPSHOT
cd jee-example
mvn clean package jboss:hard-deploy -Djboss.home=<jboss-6.0.0.Final>
start the jboss with <jboss-6.0.0.Final>/bin/run.sh (run.bat on Windws)
open http://localhost:8080/jee-example/
For more details have a look at the readme.html that is created by the archtype in the same folder as the pom.xml
To work in eclipse you should install
eclipse for Java EE Developers
m2eclipse from this update site
m2eclipse wtp extension from the m2eclipse-extra update site documentation
I did not try the eclipse part for the archetype...
