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
