Please post the relevant datasource configurations, the exception stacktraces and the relevant code where you are using this datasource.

P.S: While posting code, logs and xml content, please wrap them in a code block for better formatting.

Here's the root cause:

Caused by: java.net.UnknownHostException: MySqlDS

Which means that code is assuming that MySqlDS is a host name.

You are using a stand-alone client to access a data source from the server, which is a practice hat is frowned upon. While it is possible, it is not recommended. When using a remote JNDI lookup, you don't use the "java:" prefix. Thus line 21 should read:

DataSource ds=(DataSource)ic.lookup("MySqlDS");

In addition, you need to add "<use-java-context>false</use-java-context>" to your *-ds.xml file. See this: http://docs.jboss.org/jbossas/docs/Server_Configuration_Guide/beta500/html/ch13s15.html
