I'm trying to add new datasource mysql jdbc driver to my wildfly server
I created folder wildfly.x.x.x/modules/system/layers/base/com/mysql/main
I've got here jdbc jar file and module.xml
<module xmlns="urn:jboss:module:1.3" name="com.mysql">
<resources>
<resource-root path="mysql-connector-java-5.1.34-bin.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
</dependencies>
</module>
then added dataresource code into standalone-full.xml (under datareources tag)
<datasource jndi-name="java:jboss/datasources/MySQLDS" pool-name="MySQLDS" enabled="true" use-java-context="true">
<connection-url>jdbc:mysql://localhost:3306/test</connection-url>
<driver>MySQLDriver</driver>
<security>
<user-name>root</user-name>
<password></password>
</security>
</datasource>
but when i go to wildfly control panel http://localhost:9990/console/
dataresource doesnt appear , what did i missed?
also i'm trying to add it manually from interface i'v got this error
Unexpected HTTP response: 500

Did you add a driver definition? Your datasources subsystem should look something like this:
<subsystem xmlns="urn:jboss:domain:datasources:2.0">
<datasources>
<datasource jndi-name="java:/jdbc/myds" pool-name="myds" enabled="true" use-java-context="true">
<connection-url>jdbc:mysql://localhost/mydb</connection-url>
<driver>mysql</driver>
<security>
<user-name>foo</user-name>
<password>bar</password>
</security>
</datasource>
<drivers>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
<driver name="mysql" module="com.mysql">
<xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
</subsystem>
The driver element in the data source definition must reference a driver element by name. The module attribute must match the name of your MySQL driver module.
Actually I meet the same problem (I could add the datasources and test connection successfully before) So I'm just confused and I find a way works for me:)
See my services and I find it stopped,and I started it then tried again,It works well again! Even though your service does not stop, maybe just restart it.
I have to say it may not work for you if you never success to connect before,good luck~
There are three ways using which you can simply create datasource into wildfly
Using admin console
Manually adding into standalone.xml
Creating datasource file that is xml file.
Go to WildFly directory/standalone/deployments
Simplest way to create datasource xml with following content
<datasources xmlns="http://www.jboss.org/ironjacamar/schema">
<datasource jndi-name="APP_DS" pool-name="APP_DS" enabled="true" use-ccm="false">
<connection-url>jdbc:mysql://localhost:3306/DB_NAME</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<driver>mysql</driver>
<!-- sql to call when connection is created -->
<new-connection-sql>SELECT 1</new-connection-sql>
<pool>
<min-pool-size>5</min-pool-size>
<max-pool-size>50</max-pool-size>
</pool>
<security>
<user-name>username</user-name>
<password>password</password>
</security>
<!-- sql to call on an existing pooled connection when it is obtained from pool -->
<validation>
<check-valid-connection-sql>SELECT 1</check-valid-connection-sql>
</validation>
<timeout>
<blocking-timeout-millis>300000</blocking-timeout-millis>
<idle-timeout-minutes>5</idle-timeout-minutes>
</timeout>
<statement>
<track-statements>true</track-statements>
</statement>
</datasource>
</datasources>
Also create the database that you will use. Sometimes the reason for this error is that the database is missing.

I've installed MariaDB connector in jBPM 7.53 Final with .jar file and configured MariaDB database locally. Checked in management console and saw that datasources and JDBC connectors look good (MariaDBDS is enabled), but an error showing in runtime "Boot errors occurred during the start of server".

and I have copied the MariaDB Java connector to JBPM_HOME/modules/com/mariadb/main/mariadb-java-client-2.7.1.jar and configured the module.xml like this:

What I am missing or change in these steps? Any idea if jBPM works with the external DB or not?
#KrenarR have you set up these properties under system-properties as well?
<property name="org.kie.server.persistence.ds" value="java:jboss/MariaDBDS"/>
<property name="org.kie.server.persistence.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
You can also add the driver as a core module by means of jboss_cli:
module add --name=org.mariadb --resources=mariadb-java-client-2.7.1.jar --dependencies=javax.api,javax.transaction.api
Also check this line in the datasource:
<driver>mariadb-java-client-2.7.1.jar</driver>
I think it should be just the driver name you have defined:
<driver>mariadb</driver>
You can refer to the documentation Switch to another database
from jbpm.org for detailed steps.
I'm a Java and JBoss newbie struggling to get JBoss AS 7.0.1 working with mySQL 5.5 on my Windows 10 machine.

You have mentioned the mysql jar file name in modules as
mysql-connector-java-5.1.26-bin.jar
But in your module.xml it is incorrectly configured as
mysql-connector-java-5.1.39-bin.jar
Pls Correct your module.xml
Your driver configured in datasource with name
<driver>
com.mysql
</driver>
Update that to your correct driver name as
<driver>
mysql
</driver>
Thanks for the responses.
Turns out the mysql-connector-java-5.1.39-bin.jar file was corrupt, the java.sql.Driver file inside it was empty. Not sure how that happened!
I'm new to the JBoss application server and I tried to add a datasource for an Oracle db in JBoss EAP6.3. But I am getting the error below and seeing error while 'Testing a db connection in server'.
Please let me know if I have missed something.
Step 1-> Added below datasource in standalone.xml file
Step 2-> Created a module.xml file and placed under \modules folder as com\oracle\main
Here is my module.xml file
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="com.oracle">
<resources>
<resource-root path="ojdbc6.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
Step 3-> Copied a ojdbc6.jar file in the com\oracle\main location.
Step 4-> Started the server by standalone.bat file
<datasource jndi-name="java:jboss/datasources/OracleDS" pool-name="OracleDS" enabled="true" use-java-context="true">

please help me out how to create a connection ,

Place your ojdbc6.jar in $JBOSS_HOME/modules/system/layers/base/oracle/jdbc/main/ along with your module.xml.
The path where you have placed your ojdbc6.jar and module.xml is not
correct.
It should be modules/system/layers/base/com/oracle/main
Also define the data-source definition like:-
<datasource jndi-name="java:jboss/datasources/OracleDS" pool-name="OracleDS" enabled="true" use-java-context="true">
<connection-url>jdbc:oracle:thin:#localhost:1521:XS</connection-url>

I am trying to configure a MariaDB datasource on Wildfly. This seems like it should be a simple operation, but I can't seem to get the datasource module to load properly. I have added the maria-java-client-1.1.8.jar archive and a module.xml file to the wildfly-8.2.0.Final/modules/com/mariadb/main directory. The module.xml file is as follows:
<module xmlns:"urn:jboss:module:1.1" name="com.mariadb">
<resources>
<resource-root path="mariadb-java-client-1.1.8.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
I have also added a driver entry to the standalone.xml file as follows:
<subsystem xmlns="urn:jboss:domain:datasources:2.0">
<datasources>
<datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
<connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>
<driver>h2</driver>
<security>
<user-name>sa</user-name>
<password>sa</password>
</security>
</datasource>
<drivers>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
<driver name="mariadb" module="com.mariadb"/>
</drivers>
</datasources>
</subsystem>
Note that I have only included the driver entry for now. I will add the datasource entry after I get the module to load properly.
Now when I startup the server I get the following error:
14:14:46,570 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 26) JBAS014613: Operation ("add") failed - address: ([
("subsystem" => "datasources"),
("jdbc-driver" => "mariadb")
]) - failure description: "JBAS010441: Failed to load module for driver [com.mariadb]"
According to everything that I have read, this is the proper way to configure the driver, but it is not working for me. Does anyone know what I am doing wrong?
Thanks in advance for your help!
The first line of your module.xml has a typo (you use a colon instead of equals in xmlns=...):
Your version:
<module xmlns:"urn:jboss:module:1.1" name="com.mariadb">
Correct version:
<module xmlns="urn:jboss:module:1.3" name="com.mariadb">
I have been looking at several examples for configuring a datasource for MySQL in Jboss 7. All references i have seen for the element looks like this:
<driver name="com.mysql" module="com.mysql">
<driver-class>com.mysql.jdbc.Driver</driver-class>
<xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>
I know what the <driver-class> is but what exactly is the <xa-datasource-class> what is its purpose?
When i configured a datasource on Tomcat before i did not need to specify the xa-datasource for any database. Why is it different here?
Thanks
According to jdbc 4.0 specification (12.2): XA datasources produces XA connections capable to be used in global/distributed transactions. You might need such a connection if you need a transaction to span more than one database or a JMS calls. You can find a clear explanation of the concept here: http://www.theserverside.com/discussions/thread.tss?thread_id=21385#95346
If you don't have such a distributed transactions scenario you don't need to specify a xa-datasource, a simple datasource configuration is enough. So, if you use a simple datasource there is no need to specify a xa-datasource-class when you declare your driver.
