How to change UserTransaction JNDI name?

[jbossacm]

Hi,

I'm performing a migration from Weblogic Server to Jboss. Throughout my application I obtain explicit transactions as follows:

transaction = (UserTransaction) ctx.lookup("javax.transaction.UserTransaction");

Whereas in Jboss it seems to be:

transaction = (UserTransaction) ctx.lookup("UserTransaction");

Is there any way to change this default JNDI name?

Thanks!
