JBoss 7.1 JBAS014750: Operation handler failed to complete

Question

I just start using JBoss to explore the world of EJB, however I encounter an issue.

When I try to write a project for EJB + JPA, I encounter an error and cannot deploy the project onto the JBoss. I am using EJB 3.1 + JBoss 7.1.1 now. Please find the following server log:

I have no idea what "Operation handler failed to complete" means, all I know is JBoss does not allow me to deploy my project.

I have read a lot of materials for people who have the similar situation, most of them are related to persistence.xml / datasource / module configuration.

Please find the following files:

persistence.xml

<?xml version="1.0" encoding="UTF-8"?>

            </properties>

Code segment for standalone.xml

<subsystem xmlns="urn:jboss:domain:datasources:1.0">

                <drivers>
                    <driver name="mysqlDriver" module="com.mysql">
                        <xa-datasource-class>com.mysql.jdbc.Driver</xa-datasource-class>

                    <driver name="h2" module="com.h2database.h2">

                </drivers>
            </datasources>
        </subsystem>

Which the java:jboss/datasources/MySQLDS is the one I am planning to use.

%JBoss_Home%\modules\com\mysql\main\module.xml

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="com.mysql">
    <resources>
        <resource-root path="mysql-connector-java-5.1.31-bin.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api/>
    </dependencies>
</module>

And I have copied the mysql-connector-java-5.1.31-bin.jar into the %JBoss_Home%\modules\com\mysql\main\ directory as well.....

Please could anyone help me? I have struggled for the whole day but still cannot find a clue of what is happening......

Thank you very much.

Answer 1

I had same problem during using mysql5 but it was my bad when i defined not correct mysq jdbc driver for jboss in modules. Be sure that jboss connected to your mysql datasource correctly. for example check the jboss/modules/com/mysql/modules.xml

<resource-root path="mysql-connector-java-5.1.21.jar"/>

path has to refrence correct name of jar file. And also the jar whith same name has to locate by the modules.xml file

Answer 2

All of a sudden, I have fixed the issue.

I will post the answer here, hope it can help anyone who encounter similar situation.

Basically, I have done three things:

1. I have used JBoss EAP 6.2 rather than JBoss AP 7.1

2. I have changed jta-data-source from java:jboss/datasources/MySQLDS to java:/MySQLDS in persistence.xml

3. I have changed jndi-name from java:jboss/datasources/MySQLDS to java:/MySQLDS in standalone.xml

Thank you.
