You will not gain speed just through porting your application code to EJB's. EJB's are not a "silver bullet". You need to do some performance analysis on your existing appliation and determine why it is not performing. Begin by downloading a performance profiler like OptimizeIt! from VMGear or JProbe from Sitraka (make sure it works with your web container before downloading it!) Then you can use some of the hints and techniques in books like Peter Haggar's "Practical Java" or Dov Bulka's "Server-Side Programming Techniques (Java(TM) Performance and Scalability, Volume 1)". Another good reference is Harvey Gunther's short paper on the 20 biggest performance stealers in Servlet and EJB code (http://www-4.ibm.com/software/webservers/appserv/ws_bestpractices.pdf) Kyle ------------------ Kyle Brown, Author of Enterprise Java (tm) Programming with IBM Websphere See my homepage at http://members.aol.com/kgb1001001 for other WebSphere information.
