Adding a module in WildFly 8.2.0 Final release - java

I am new in JBoss and I try to add a jdbc driver for derby as a module in WidlFly 8.2.0.
What I did:
I added the org/apache/derby/main folder in the JBOSS_HOME/modules/system/layers/base directory
In this new folder, I added derbyclient.jar (from jdk 1.8.0_40, it contains the driver) and a new module.xml file.
The module.xml file is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.apache.derby">
<resources>
<resource-root path="derbyclient.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
</dependencies>
</module>
Then, I updated the standalone.xml file as follows:
addition of this tag (in <extensions>): <extension module="org.apache.derby"/>
Declaration of my datasource and of the driver:
<datasource jndi-name="java:/DerbyDS" pool-name="DerbyDS" enabled="true" use-ccm="false">
<connection-url>jdbc:derby:MyDB;create=true</connection-url>
<driver>org.apache.derby</driver>
<security>
<user-name>demo</user-name>
<password>demo</password>
</security>
<validation>
<validate-on-match>false</validate-on-match>
<background-validation>false</background-validation>
</validation>
<statement>
<share-prepared-statements>false</share-prepared-statements>
</statement>
</datasource>
<drivers>
<driver name="org.apache.derby" module="org.apache.derby">
<xa-datasource-class>org.apache.derby.jdbc.ClientXADataSource</xa-datasource-class>
</driver>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
</drivers>
I am getting the following error when I start WildFly:
`16:19:49,856 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) JBAS014613: Operation ("add") failed - address: ([

Do you know what I did wrong?
Thanks in advance

I finally solved the issue by:
adding derbyclient.jar in the standalone directory (where my applications are deployed)
modifying the datasource declaration in the standalone.xml to make it reference the jar name :
<datasource jndi-name="java:/DerbyDS" pool-name="DerbyDS"enabled="true" use-ccm="false"> <connection-url>jdbc:derby:MyDB;create=true</connection-url> <driver>derbyclient.jar</driver>...
(I deleted the <drivers> tag, I don't use it anymore.)
So, I don't have errors anymore when I start WildFly. The derby driver is not declared as a module, but it will be shared among my different applications, so that's ok.

Your URL jdbc:derby://:MyDB looks invalid.

keycloak , aws secrets manager and postgres

Hoping some one can point me in the right direction.
Trying to get away from hardcoded passwd for postgres in the config file for keycloak 19. I dont want to make changes code nor write a custom class based on sdk aws provides, if possible ; keycloak 19.x and using legacy/wildfly
what is needed here in the code below
jdbc-secretsmanager:postgresql://somename.rds.amazonaws.com:5432/keycloak?ssl=true;sslfactory=org.postgresql.ssl.NonValidatingFactory

After satisfying all dependencies/jars, it throws error

What or how is this supposed to be configured? Appreciate any pointers. Thanks

Wildfly server doesn't work, errors WFLYCTL0412 & WFLYCTL0180

I am trying to add a mysql datasource to my wildfly 26 server and when I deploy it I encounter the following error:
I saved a copy of my standalone and tried to redo it, since I've heard the xml can be quite tricky, however that didn't change anything. Also looked for blankspaces in the beginning of each xml document as per another stackoverflow post - but no bueno.

MongoDB DataSource Configuration In JBoss Server

How to configure MongoDB DataSource JNDI in JBoss Server.
I downloaded MongoDB jar (mongo-java-driver-3.4.2.jar) and deployed using admin console, it got successfully deployed but when I went to add Datasource in customize option I am not able to see MongoDB driver, the only one option available was h2. Why so? Do I have to do any other configuration change or am I missing any step?
I Even tried to manually create the MongoDB driver and datasource but that is also not working.
I placed module.xml and mongo-java-driver- 3.4.2.jar to the following path
..\devstudio\runtimes\jboss-eap\modules\system\layers\base\org\mongodb\main
--------- module.xml ---------------------
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.mongodb">
<resources>
<resource-root path="mongo-java-driver-3.4.2.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
--------------standalone.xml ------------
<datasource jndi-name="java:jboss/datasources/mongodb" pool-name="mongodb"
enabled="true" use-java-context="true">
<connection-url>jdbc:mongodb://127.0.0.1:27017/example;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>
<driver>mongodb</driver>
</datasource>
<driver name="mongodb" module="org.mongodb">

Could you let me know how to do JNDI Datasource configuration in JBoss Server ?? Please explain in detail as I am new for JNDI Configuration

WildFly jdbc connection with Sybase

I'm trying to migrate from Glassfish to WildFly 10, my app connects whit Sybase ASE database. I put jconn3.jar in WILDFLY_HOME\modules\system\layers\base\com\sybase\sybase\main, created modules.xml with the following content:

Unable to create oracle data source in Jboss EAP 7.0 server

I need to create an oracle data source in JBOSS EAP 7.0 server
I deployed ojdbc6.jar from the JBOSS management CLI(Command Line Interface) using the below command
deploy <PATH_TO_ORACLE_DRIVER_JAR>
I could see the server log as below after the driver is deployed

1) May I know what is causing this issue? What dependency is missing?
2) Is installing JDBC driver as a JAR deployment for data source creation correct method?
Install a JDBC Driver as a Core Module
Create a directory under $JBOSS_HOME/modules. In this example: "$JBOSS_HOME/modules/com/oracle/jdbc/main".
Put the the JDBC driver jar (ojdbc6.jar) in this directory.
Create a module configuration file module.xml:
Example Oracle JDBC Driver module.xml File
<?xml version="1.0" ?>
<module xmlns="urn:jboss:module:1.1" name="com.oracle">
<resources>
<resource-root path="ojdbc6.jar"/>

<module name="javax.transaction.api"/>
</dependencies>

Example Management CLI Commands
This example configuration can be achieved by using the following management CLI commands.
1# Add the Oracle JDBC driver as a core module.
module add --name=com.oracle --resources=/path/to/misc/jdbc_drivers/oracle/ojdbc7.jar --dependencies=javax.api,javax.transaction.api
2#Register the Oracle JDBC driver.
/subsystem=datasources/jdbc-driver=oracle:add(driver-name=oracle,driver-module-name=com.oracle,driver-xa-datasource-class-name=oracle.jdbc.xa.client.OracleXADataSource)
3#Add the Oracle datasource.
data-source add --name=OracleDS --jndi-name=java:jboss/OracleDS --driver-name=oracle --connection-url=jdbc:oracle:thin:#localhost:1521:XE --user-name=admin --password=admin --validate-on-match=true --background-validation=false --valid-connection-checker-class-name=org.jboss.jca.adapters.jdbc.extensions.oracle.OracleValidConnectionChecker --exception-sorter-class-name=org.jboss.jca.adapters.jdbc.extensions.oracle.OracleExceptionSorter --stale-connection-checker-class-name=org.jboss.jca.adapters.jdbc.extensions.oracle.OracleStaleConnectionChecker
