Re: Problem with UserTransaction reference within Servlet code.

[Jon Wingfield]

The answer's in the question ;)
Tomcat is not a J2EE Server but an implementation of the Servlet 
Specification (which is but a part of the whole J2EE spec).
Tomcat's JNDI lookups are in-process only.

Need an open source J2EE container? Have a look at JBoss...

Can anyone help!

Problem with UserTransaction reference within Servlet code.

When you reference UserTransaction object in your Servlet Code, as from J2EE Specification: The J2EE Product Provider is responsible for providing an appropriate object as required ....

There's a code snippet.

Context initCtx = new InitialContext();
UserTransaction tx = (UserTransaction)initCtx.lookup("java:comp/UserTransaction");
This works fine on J2EE Impementation Servers but fails on Tomcat 4.1.3. 

Exception:

javax.naming.NameNotFoundException: Name javax.transaction.UserTransaction is not 
bound in this Context
        at org.apache.naming.NamingContext.lookup(NamingContext.java:811)
        at org.apache.naming.NamingContext.lookup(NamingContext.java:194)
        at org.apache.naming.SelectorContext.lookup(SelectorContext.java:183)
        at javax.naming.InitialContext.lookup(InitialContext.java:347)
 
Thanks
