Hi, Tomcat has its own, org.apache.catalina.naming.java.javaURLContextFactory. See code at http://cvs.apache.org/viewcvs.cgi/jakarta-tomcat-catalina/catalina/src/s hare/org/apache/naming/java/ and a level above for the entire naming package which might be of interest to you.
However, it is expected and supported that users use other InitialContextFactories to connect to different remote servers via JNDI. I routinely use the JBoss, OpenJMS, and Weblogic initial context factories in exactly the manner in your code snippet, without a problem. The client jar file for the remote server, which contains the initial context factory implementation, should be in the WEB-INF/lib directory of your web application.
