ClassCastException while doing REMOTE ejb lookup
Hi I'm doing a REMOTE (not local, not same JVM, not same Orion) lookup from a servlet running in Orion152 application to an ejb deployed in Orion152 application on a remote and different physical machine. I can establish the correct Initial Context and locate the required object. But this object is loaded in the servlet using a ClassLoader that is different from the default ClassLoader of the servlet. The result is a ClassCastException when doing a narrow using this object and the class as loaded by the default ClassLoader. The narrow works fine when the object's ClassLoader is used to locate the class to be used for the narrow. However, it seems that this ClassLoader is then retrieving classes from the remote machine. Obviously I need the classes also on the web machine accesible by the default ClassLoader so that classes that depend on these remote classes can load and JSP's can compile. Any ideas will be greatly appreciated. Please reply at least to my email. -- Regards Theo van Niekerk Generation 5 tel: +27 21 883 88 58 mob: +27 82 44 81 222 msg17464/pgp0.pgp Description: PGP signature

Hi, Michael J. Cannon wrote: Why Orion? Because from day-to-day, no matter how many CPUs, no matter what the BEA Sales Executive's outstanding Mercedes lease payment, no matter what...Orion is USD$1500 / physical server license for deployed applications and every developer seat is free...because IT management need never again sweat out BEA 'Assistance' shakedowns and audits... Think of Corporate psychology as akin to social-victim psychology: why buy a perfectly good pair of jeans that cost $20.00 when you can spend $200.00 and buy the same pair of jeans from Calvin (coke up the nose) Klein? Why buy a $3.00 dollar bottle of simple detergent to wash your hair, when you can pay $55.00 for a bottle of shampoo (if you please?) from Mistuh Calvin Klein or whoever? Especially if the money you're spending is other people's money? And: Application development, which is what people do with app servers, is a very technical thing. It requires experience and knowledge. ^^^ A good point! BUT I think J2EE is a technology that is heading for the scrap heap if it can't find a way to make itself FAR simpler and FAR easier to program and develop. J2EE is the Java Enterprise version of assembler! Which leads to an observation about Techo-psychology: why write an enterprise application in 2 hours when you have a technology that can guarantee you a job for four weeks, and be understood by almost no-one outside the Masonic Guild of J2EE Developers? Complete with Overware and Underwear and Middleware and all Wrapped in UML and XML and WhatTheHell? ;) Freddo
Best way to add user records to EJBUserManager...
I am using EJBUserManager for security in Orion. What is the best way to update users? Should I directly use EJBUser EJB or use the API's in the UserManager. If UserManager is the answer, then how do I get access to it while running in Orion? Thanks -AP_

I am working on it and will fix it in the next day or 2.
