RE: BEA licenses BlueDragon for WebLogicr
-Original Message- *Really* ? What's up ? Number one peeve: Can't pass java objects you created yourself to an EJB in a different application on the same server: MX uses the classloader of the various objects/parameters to figure out which method to call, so it claims that no such method exists. Solutions (in order of banging your head against the wallness): - fiddle with classloader settings in bea - only works if you want to talk to EJB's from ONE other app... - have the EJB give you blank instances of the objects which you then customize and return to it. You get to handle the why do we need this method? questions every time you break in a new Java dev. - Dynamic proxy (which is how we went) - works, but that's code for nothing, since a bog standard struts application deployed right next to the cf one can do exactly what we're trying to do, no muss, no fuss. Much ribbing by Java devs ensues. Also, there's some kind of issue with memory not being released when you redeploy cf - do it enough times and bang, out of memory error. Which means you should restart the server when you redeploy the app. Round here, that means a weekend, which means that operations hates you for making them work on saturdays... Then, there's the occasional null pointer exception being thrown from the middle of code you haven't touched in donkey's years. solution: bounce the app or better yet, the server. Thank god that only happens in dev... so far. My opinion: i just don't see what *real* benefits you get from the J2EE configuration; i'm sure that the adobe/macromedia marketing department finds it very useful to sell into big companies on the Enterprise ticket, but my suggestion would be to stick with enterprise on JRUN just my 0.02$ /t ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:238077 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54

We also use WLs JMS queues, for instance.

Actually, you *can* do that with a normal java web app - Struts, in our case, but i guess a jsp could do it as well.

All up to date for CF6.1 - and, again, the problem only affects (re)deploying the cfmx app, not other java apps on the same wl server.
