JBoss AS 7 and MySQL - Can't start server

Question

I've followed this tutorial to set up MySQL with JBoss AS 7. Unfortunately the server hangs on the message:

INFO  [org.apache.coyote.http11.Http11Protocol] (MSC service thread 1-1) Starting Coyote HTTP/1.1 on http--127.0.0.1-8080

And nothing happens.

What could cause this problem?

This is the corresponding content of my standalone.xml:

            </datasources>

Whereas database, username and password are set correctly.

Answer 1

The problem is 2 driver definitions in META-INF/services/java.sql.Driver.
Also this problem may be cause by MySQL Driver version.

1)Change your MySQL Driver version.(May be MySQL JDBC Driver 5.1.30 and up has this issues, you should change lower version)
OR
2)Add eg: line to the "drivers" section in the subsystem "datasources" in standalone.xml

eg:

<driver-class>com.mysql.jdbc.Driver</driver-class>

Answer 2

I had the same issue, but could resolve by downgrading the MySQL driver version to mysql-connector-java-5.1.29.jar

Here is the 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-5.1.29.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
  </dependencies>
</module>

Works well with JBoss AS 7.1.1
