I have a web application I am deploying in wildfly-10.0.0. It requires a mysql xa driver. I have the following error:
2015-10-13 12:25:37,979 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 33) WFLYCTL0013: Operation ("add") failed - address: ([ ("subsystem" => "datasources"), ("jdbc-driver" => "com.mysql") ]) - failure description: "WFLYJCA0041: Failed to load module for driver [com.mysql]"
The modules directory is as follows:

03/17/2015 05:21 AM 968,670 mysql-connector-java-5.1.35-bin.jar
The module.xml file is:
<?xml version="1.0" encoding="UTF-8"?>

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

</module>
I added the driver and datasource to the datasources section of standalone.xml:
<xa-datasource jndi-name="java:/jdbc/MyXaDS" pool-name="MyXaDSPool" enabled="true" use-ccm="false">
<xa-datasource-property name="URL">

</driver>
</drivers>
The error you get means that wildfly expects a module called com.mysql
but it doesn't exist or it isn't registered under that name.
You are missing one step, which is registering the datasource jdbc driver. The first step of course being adding the mysql-connector-java-5.1.35-bin.jar
file and module.xml
file in WILDFLY_HOME\modules\system\layers\base\com\mysql\main
.
To get rid of your error, stop wildfly, delete the the driver declaration in your standalone.xml by removing these lines; We'll let the /subsystem command create this entry.
<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>
Open your command prompt and navigate to WILDFLY_HOME\bin\
and run the following commands.
Connect to jboss cli by running :
jboss-cli.bat --connect
. In case your management console is running on a different port say , localhost:9991, usejboss-cli.bat --connect --controller=127.0.0.1:9991
Then register the jdbc-driver with the following command
/subsystem=datasources/jdbc-driver=com.mysql:add(driver-name=com.mysql,driver-module-name=com.mysql,driver-xa-datasource-class-name=com.mysql.jdbc.jdbc2.optional.MysqlXADataSource)
You should get the response {"outcome" => "success"}
if this was successful.
From there, reload your server and you should get rid of that error.
I got pointers from This link
I'm not really sure what the issue could be. The message isn't very informative.
That said the following add-mysql.cli
script worked for me.
module add --name=com.mysql --resources=~/Downloads/mysql-connector-java-5.1.37/mysql-connector-java-5.1.37-bin.jar --dependencies=javax.api,javax.transaction.api
batch
/subsystem=datasources/jdbc-driver=com.mysql:add(driver-name=com.mysql, driver-module-name=com.mysql, driver-xa-datasource-class-name=com.mysql.jdbc.jdbc2.optional.MysqlXADataSource)
/subsystem=datasources/xa-data-source=mysql:add(driver-name=com.mysql, jndi-name="java:/jdbc/MySQLXA", enabled=true)
/subsystem=datasources/xa-data-source=mysql/xa-datasource-properties=URL:add(value="jdbc:mysql://localhost:3306/temp?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8")
run-batch
I didn't write all the properties defined in your data source configuration, but this did work.
WildFly 10 has some change in jca caused CLI create xa ds have some issue. https://issues.jboss.org/browse/WFLY-6773 https://issues.jboss.org/browse/WFLY-6789 https://issues.jboss.org/browse/WFLY-6774
But create xa datasouces use below commands works
xa-data-source add --name=MariaDBXADS --driver-name=mariadb-xa --jndi-name=java:jboss/datasources/MariaDBXADS --user-name=jdv_user --password=jdv_pass --use-java-context=true --xa-datasource-properties=[DatabaseName=>products, PortNumber=>3306, ServerName=>localhost]
WILDFLY 10 using mysql 5.7
follow this steps: comment or delete exampleds in standalone.xml
into jboss-cli.bat --connect after execute command [standalone@localhost:9990 /] /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)
should be ok
this modified standalone.xml, then add
jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE h2 sa sa --> jdbc:mysql://localhost:3306/wildfly mysql root jdfoxito10 com.mysql.jdbc.jdbc2.optional.MysqlXADataSource
should look like!
and module.xml put in
\java\server\wildfly-10.1.0.Final\modules\system\layers\base\com\mysql\main
mysql-connector-java-5.1.40-bin.jar (come installer mysql-installer-community-5.7.15.0.msi) module.xml
and content from module.xml like:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="com.mysql">
<resources>
<resource-root path="mysql-connector-java-5.1.40-bin.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
and ready, JAVA_HOME should be ok
