Hi, I am using tomcat v4.0.1 I successfully created a datasource and when I tried to lookup UserTransaction in java:comp:/env I got a name not found excpetion. but with some hit and trial I looked up in java:comp I found the object. If I am not missing anything. I request to either change the documentation to reflect the jndi location or modify the tyrex to register the UserTransaction in java:comp/env . Thanks and Regards, Sri K Ganjam
