JNDI Caching
Here’s a page from theinfocenter on how to set up JNDI caching for WebSphere 5: http://publib.boulder.ibm.com/infocenter/wasinfo/index.jsp?topic=/com.ibm.websphere.nd.doc/info/ae/ae/rnam_example_behavior.html
I’m not convinced about the wisdom of this: http://www-106.ibm.com/developerworks/java/library/j-ejb0924.html but there are several patterns which advocate caching of JNDI. This would seem to be a pattern for container vendors not developers.
