Problem accessing Entity Bean, Getting SystemExceptionInterceptor warning
Hello,
I need some help. I've been having problems accessing an entity bean from my
session bean. I've coded similar EJBs before and they've successfully run on
Geronimo 1.0. I tried using the upgrade.jar utility on these old beans, but
was unable to get them to deploy. When the example programs became
available, I gave up trying to use the upgrade tool. Now, the application
seems to deploy just fine with no error messages being returned in the
console window, but there are some debug messages in the log file.
When I access my application, the session bean seems to locate the entity
bean successfully. But when I call a method belonging to that entity bean, I
get a "SystemExceptionInterceptor" warning. I'm not sure what this means,
other than I'm doing something wrong.
I'm using Geronimo 1.1 with Tomcat and Java 1.4.2_10. The descriptor files
are modelled after the Bank demo supplied in the user manual which I was
able to get running. My test application is deployed as an ear file via Hot
Deployer.
The descriptor files (ejb-jar.xml, openejb-jar.xml) and stack trace are
below for my test application. I hope someone can point out what I'm missing
or doing wrong.
Thanks,
Dale

Re: Problem accessing Entity Bean, Getting SystemExceptionInterceptor warning
Posted by Dale de los Reyes <dr...@hotmail.com>.
Hi Lasantha,
I finally got my entity bean working. The requisite "user-error" applies
here (*blush*). What happend is that I started out my entity bean using CMP.
When I ran into problems, I switched it to BMP. However, in the course of
the switch, I forgot to remove the "abstract" keyword at the beginning of
the class definition when implementing the entity bean! Once I removed it,
there was much rejoicing. I have since been able to get CMP working as well.
Ugh, I'm so embarrased.
Thanks for responding and thank you for your example code! It really helped
me out a lot!
Very much appreciated,
Dale

Hi Dale,
Can you give more information on your client application?
Also have a look at
http://cwiki.apache.org/confluence/display/GMOxDOC11/EJB+sample+application.
But it is not yet finished. Hope it this will help to you too.
