jboss 6.2 EAP unable to add mysql datasource and module - mysql

Question

I am having trouble to add a mysql jdbc driver to my jboss 6.2 EAP. I followed each step as described there : Install a JDBC Driver as a Core Module
but whenever I try to create datasource in command line, jboss return this message:
[standalone#localhost:9999 /] /subsystem=datasources/jdbc-driver=mysql:add(driver-name=mysql,driver-module-name=com.mysql,driver-xa-datasource-class-name=com.mysql.jdbc.jdbc2.optional.MysqlXADataSource)
{
"outcome" => "failed",
"failure-description" => "JBAS014749: Operation handler failed: Service jboss.jdbc-driver.mysql is already registered",
"rolled-back" => true
}
I obtain the same message at boot time when I try to manually add datasource configuration to my standalone-full.xml file.
I placed my jar driver in EAP_HOME/modules/com/mysql/main/ and this is my module configuration:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="com.mysql">
<resources>
<resource-root path="mysql-connector-java-5.1.31.jar" />
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
My development environment: ubuntu 14.04, sun jdk 7 or 8.
thanks

Answer 1

The problem is caused by 2 entries in META-INF/services/java.sql.Driver in the MySQL JDBC driver JAR:
com.mysql.jdbc.Driver
com.mysql.fabric.jdbc.FabricMySQLDriver
JBoss EAP 6.2 probably doesn't expect more than 1 entry there. I filled an issue with the problem description.
Nevertheless, you can define value for driver-class-name attribute in the CLI command and you should get the expected behavior:
/subsystem=datasources/jdbc-driver=mysql:add( \
driver-name=mysql, \
driver-module-name=com.mysql, \
driver-xa-datasource-class-name=com.mysql.jdbc.jdbc2.optional.MysqlXADataSource, \
driver-class-name=com.mysql.jdbc.Driver)

#kwart's answer didn't work for me (running on JBoss EAP 6.2.0.GA (AS 7.3.0.Final-redhat-14), using mysql-connector-java-5.1.32 jdbc driver), I fixed it by adding the following directly to standalone.xml
<subsystem xmlns="urn:jboss:domain:datasources:1.1">
<datasources>
<!-- snip -->
<drivers>
<driver name="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>
</drivers>
</datasources>
</subsystem>
Make sure the server is stopped when you do this otherwise the change will disappear..

Answer 3

I had the same problem and solved with an old version driver: mysql-connector-java-5.1.27-bin.jar
org.jboss.msc.service.DuplicateServiceException: Service jboss.jdbc-driver.mysql is already registered -> https://access.redhat.com/site/solutions/878573

Answer 4

I had the same problem using mysql-connector-java-5.1.33.jar and solved it by using an old version: mysql-connector-java-5.1.29.jar.
The server now starts properly
