I am trying to learn the new technologies CDI + JPA + EJB + JTA + JSF so, i have downloaded the sample project from JBoss-Community--> jboss-as-kitchensink(from JBoss in my Eclipse juno).
I am Trying to connect the kitchen with my PostgreSQL database:
My database name is : sampledb
My Table(Member) Structure is : Database name :QUICKSTART_DATABASENAME
CREATE TABLE member
(
id integer,
name text,
email text,
phone_number numeric
);
I have edited this files in my kitchen Project :
persistence.xml
<persistence version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="

<!-- Properties for Hibernate -->
<property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
<property name="hibernate.show_sql" value="true"/>
</properties>
</persistence-unit>
</persistence>
I Added the Dependency in pom.xml:
<!-- PostgreSQL Dependency -->
<dependency>
<groupId>postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.1-901.jdbc4</version>
</dependency>
But i'm getting error:

What should i do so that i can run this application with my database to insert the data.
Do i need to change any code in .java files or any .xml file to make it work?
EDITED after Comments: By Following this link,I have configured my PostgreSQL into JBoss manually
by setting up the standalone-full.xml file of JBoss..

Answer :
Install the PostgreSQL driver and use the XML so that u can make it work.
Follow The Steps : (Suggested By #Craig Ringer) is Very HelpFull
Download PgJDBC. I'm assuming you're using postgresql-9.2-1003.jdbc4.jar, the current version at time of writing. Adjust any filenames to match if you need a different version.
Now deploy the JDBC driver to JBoss AS 7 by putting it in the deployments folder or using the deploy command in jboss-cli. This will work for most, but not all, purposes.
Alternately, you an define a PostgreSQL JDBC driver module:
Create the path $JBOSS_HOME/modules/org/postgresql/main. The modules/org part should already exist, make directories for the rest.
In $JBOSS_HOME/modules/org/postgresql/main/modules.xml with the following content, changing the resource-root entry for the PgJDBC driver to refer to the driver you wish to use.
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.postgresql">
<resources>
<resource-root path="postgresql-9.2-1003.jdbc4.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
<module name="javax.servlet.api" optional="true"/>
</dependencies>
</module>
Into the same directory as modules.xml place postgresql-9.2-1003.jdbc4.jar
Open jboss-cli by running $JBOSS_HOME/bin/jboss-cli --connect
Run the command:
/subsystem=datasources/jdbc-driver=postgresql-driver:add(driver-name=postgresql-driver, driver-class-name=org.postgresql.Driver, driver-module-name=org.postgresql)
Now create any required data sources, etc, using postgresql-driver as the driver name.
You can create a datasource via the web ui, with jboss-cli with the data-source create command (see data-source --help, data-source add --help), or by deploying a -ds.xml file like this:
<?xml version="1.0" encoding="UTF-8"?>
<datasources>
<datasource jndi-name="java:/datasources/PostgresqlDS" enabled="true" use-java-context="true"
pool-name="PostgresqlDS">
<connection-url>jdbc:postgresql:dbname</connection-url>
<driver>postgresql-driver</driver>
<security>
<user-name>username</user-name>
<password>password</password>
</security>
</datasource>
</datasources>
For KitchenSink Example: I Tried With These, It Worked till Connection and All the Things.Still It Should be updated After Later...

But Where i'm Stuck is :
I'm Unable to insert the Data Inot the Database! It is raising an error as
ERROR: relation "hibernate_sequence" does not exist Position: 17
I need A Help To Configure It .. I tried in MANY ways
I dont know if you still need help with this but I encounted similar error when deploying my application to the Openshift.
First I connected over SSH to openshift console. Then I ran psql (you can run psql on your host from $POSTGRES_HOME/bin/psql) with credentials for my postgres connection and used \ds and \dt to determine that hibernate_sequence was a table and not a sequence.
So I dropped it: DROP TABLE hibernate_sequence;
And recreated it as a sequence: CREATE SEQUENCE hibernate_sequence;
For the Error Raised as: ERROR: relation "hibernate_sequence" does not exist Position: 17
i had created a SEQUENCE as Suggested by #Martin Nuc.
To Check Whether there is a Sequence in the Database or not use \ds : Lists the Sequences in the database.
CREATE SEQUENCE hibernate_sequence;
Then i had raised with few more errors like -> Type Cast like things then after Clearing those Errors It Worked ! Finally :-)
Thanks for the Support Every1 :)
Alternatively you can also add #Generator instead of being auto, you can add sequence and specify a sequence generator that is used by PostGre which is ${table_name}_${pk}_seq.
Nevertheless, One draw back of doing this is to making your app tightly coupled to sequences.
Another strategy is to make hibernate create that hibernate_sequence if you force it to create DDL.

My question is: How do I map a datasource to a specific jndi-name configured inside wildfly so that multiple deployed .war-files each can use their own specific datasource. The mapping should take place at deployment so that a configuration inside wildfly and the specific project is sufficient.
We got a project which supports multi-tenancy. The structure is as follows:
customerSpecificProject
|-- ui (generic)
|----database (generic)
|----services (generic)
|----etc...
In the database-project a standard datasource is specified which goes by a standard jndi-name java:/xyzDS. Since we migrated from tomcat to wildfly we want to make use of the ability to host multiple applications in our AS.
To achieve this we have to map the java:/xyzDS to the datasources defined in the standalone.xml:
<subsystem xmlns="urn:jboss:domain:datasources:4.0">
<datasources>
<datasource jta="true" jndi-name="java:/customer1DS" pool-name="c1DS" enabled="true" use-ccm="true">
...
</datasource>
<datasource jta="true" jndi-name="java:/customer2DS" pool-name="c2DS" enabled="true" use-ccm="true">
...
</datasource>
Therefore we tried to use the jboss-web.xml located in the WEB-INF folder of our customerProject:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.jboss.com/xml/ns/javaee
http://www.jboss.org/j2ee/schema/jboss-web_5_1.xsd">
<resource-ref>
<res-ref-name>java:/xyzDS</res-ref-name>
<jndi-name>java:/customer1DS</jndi-name>
</resource-ref>
</jboss-web>
persistence.xml inside the database-Project:
<?xml version='1.0' encoding='UTF-8'?>
<persistence version="2.1"
xmlns="http://xmlns.jcp.org/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_1.xsd">
<persistence-unit name="xyzDB" transaction-type="JTA">
<jta-data-source>java:/xyzDS</jta-data-source>
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>...</class>
...
<class>...</class>
<shared-cache-mode>NONE</shared-cache-mode>
<validation-mode>NONE</validation-mode>
<properties>
<property name="eclipselink.weaving" value="static" />
</properties>
</persistence-unit>
</persistence>
It does not seem to be working. I talked to a colleague who had a similar issue and resolved it in the corresponding way for a websphere AS. I do not know if the problem resides in the structure having a nested databaseProject inside another lib (ui) for the actual customerProject or if it is caused by bad configuration.
Also we use the #Resource Annotation inside some DAOs:
#Resource(lookup = "java:/xyzDS")
private DataSource dataSource;
Maybe the mapping works but not for the annotations inside the compiled DAOs? But I do not understand why that should not work.

Edit: Already tried adding:
<property name="wildfly.jpa.twophasebootstrap" value="false"/>
To persistence.xml
Have you checked the question/answer in wildfly-development.1055759.n5.nabble.com? In this exchange, it was determined that the persistence unit needed a hint in the form of
<property name="wildfly.jpa.twophasebootstrap" value="false"/>
I don't know if this is applicable in your case, but is worth looking at.
I am trying to create web service with creation to oracle database. As a server I use Wildfly so I initialized JNDI connection using Administrative console in browser.

I am trying to upgrade to JBoss 7; however, my datasource is not creating a connection. I did not deploy any WAR files. I am testing the connection by using the admin console. In standalone.xml, I configured the datasource as follows:
<subsystem xmlns="urn:jboss:domain:datasources:1.0">
<datasources>
<datasource jta="false" jndi-name="java:jboss/projectDS" pool-name="projectDS" enabled="true">

<password>XXX</password>
</security>
</datasource>
<drivers>
<driver name="ojdbc6" module="com.oracle" />
</drivers>
</datasources>
</subsystem>
The ojdbc6.jar driver is in the following folder %JBOSS_HOME%\modules\com\oracle\main. The entry in my module.xml reads as follows:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="com.oracle">

</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
The error that I receive in my server log when I test the connection from the admin console is:
07:47:11,863 WARN [org.jboss.jca.core.connectionmanager.pool.strategy.OnePool]

Thanks in advance!
Deploy the oracle driver jar to jboss from the console. Its something like localhost:9990/console with credential test/test123
From the datasource option, check whether you can see your datasource java:jboss/hqiis over there or not. If not, try to create the datasource from the console instead of configuring through xml.
Also check the data source status from the jboss-cli:
a. From command prompt, enter into JBOSS_HOME\bin
b. Type connect YOUR_IP:YOUR_PORT (example 192.169.1.10:9999)
c. Type this to see whether your datasource is available or not:
/subsystem=datasources/data-source=hqiis:test-connection-in-pool
You should see a msg like below if you are having a configured datasource named hqiis
connection-in-pool
{
"outcome" => "success",
"result" => [true]
}

Looks like your EAR requires some JNDI bindings to be configured in JBoss, likely DataSources for use by JPA. Java EE applications can have dependencies on services provided by the container and those are usually looked up using the naming service (JNDI).
Check the deploy/install instructions that come with the EAR you're trying to deploy, or refer back to whoever provides the application. Unfortunately it's not possible to provide much more help without much more info.
We are using Jboss 4.2.3 with EJBs and hibernate.
Currently we defined 3 db connections in our persistence.xml file (one for reads (tx-local), one for writes (no-tx) and one for statistics (no-tx)), and when we add a forth db connection which is also (no-tx) and map a couple of entities to it, the machine starts to show an unusual load.
If we remove this connection (no one is using it still) the load get back to normal.
I guess it is some sort of configuration problem with JBoss, but I'm not sure.
any assistance will be appreciated.
thanks.
