Java EE (Java Enterprise Edition) General Discussion

hi,

in my project i am trying to get an instance of javax.transaction.UserTransaction in tomcat4.0 using jndi.

i have added the following tag in my server.xml for this regard as well as in web.xml as it is mentioned in the docs of tomcat4.0

<Resource name="jta/UserTransaction" auth="Container" type="javax.transaction.UserTransaction"/>

when in my JSP application i try to retrieve the instance it throws an exception on browser that says

Exception Report:
javax.servlet.ServletException: Cannot create resource instance
Root Cause:javax.naming.NamingException: Cannot create resource instance

the code i hve written in jsp page is::

Context ctx1 = new InitialContext();
Context ctx2 = (Context)ctx1.lookup("java:comp/env");
UserTransaction ut = (UserTransaction)ctx2.lookup("jta/UserTransaction");

any idea what shud be done to mend this..

BTW i am using mysql as database and mysql's type 4 jdbc2.0 compliant driver.

please suggest its urgent..

thanks in advance,
