Re: Too much caching? - the database has changed
Thanks for the help Tim. I am not sure I like this solution. Why do I have to go and change this in the application-deployments folder? The same question applies to the table name for the CMP Beans. How do I choose a table name different than the default one without touvhign the application-deployments folder? Wouldn't make more sense if I can change these things in the "ejb-jar.xml" that is part of the EJB package? Danut At 08:55 PM 2/5/2001 -0500, Tim Endres wrote: Check the docs.

Re: Too much caching? - the database has changed
You should not be changing the deployment folder files directly, except to check to see if something works. You should create your own orion-ejb-jar.xml file in your own EAR (or build directory if you deploy directly). Orion will then pickup your version of orion-ejb-jar.xml and add anything else that it needs, and place the result into application-deployments. tim. Thanks for the help Tim.

Re: Too much caching? - the database has changed
Danut, please reread my posting. I wrote that it is not meant as a flame and I was dead serious about that. you are discussing with people on this list about why something has to go where in the deployment files, so you obviously have to know. if you don'zt trake the time to learn those concepts IMHO you will run against the wall head first with whatever ejb server you use. just take a day of reading the javasoft tutorials, some spec material etc. and it will save you lots of time (much more than a day) of helplessly poking around in deployment files no matter what servers they are for. understanding those concepts means that you know what to expect to be the same with each server and what will be different. that is all I am saying and I still think I'm actually helping you with those statements ;-) and yes this is a free discussion list without rules and nobody is restricting you. peace, robert (not born as and not yet become a guru either ;) At 15:04 06.02.2001 , you wrote: Thank you for your advise but I am afraid I do not have time. I have to deal with new things especially working with Orion, WebLogic, WebSphere (and each of them has many things different than the others) and also learn how to administer and program under Oracle (plus learn Java!) and finish everything by ... yesterday. I just came up withy an idea that makes sense for my level of understanding and I didn't think it will offend someone. I thought it is a free discussion list that doesn't have restriction rules and anyone who needs help can ask for it.
