Deployment problems, random exceptions

Question

Hey,
We are having some problems getting our application to deploy. First of all the
context:
We are running Weblobic 6.0sp2 on jdk1.3.1_01 on a Windows platform.
We have an application consisting of 102 beans about 90 of those are Entity Beans,
the rest are Session beans. The beans are split up in separate components, about
15 of them. The components are ejbc-ed and deployed as separate jar 's. They
don't use remote relationships to connect between the components, but Home interfaces
in combination with finders.
To allow the components to be build and deployed separately, we put the util classes
and the home and remotes in the system classpath. That of course makes hot deployment
impossible, but we don't need to bundle the application into an ear file.
The deployment goes fine, but when we run the application we get 2 different exceptions.
These are NoSuchMethodException and UnMarshallException. Sometimes it 's the
first, sometimes the second, without even redeploying or rebuilding the application.
And they occur on different ( random ) places in the code.
Any help would be Extremely much appreciated,
Lieve

Thanks,
It works now. It 's crazy, but solves the problem.
Have a nice day,

Hello Lieve,
The problem is maybe related to naming. I had problems once with a jar
in the
system classpath, containing util classes, that was called base.jar
It seems that naming it differently solves the problem. If you name
it something
like base-<something>.jar, all the crazy problems will be solved. I
honestly
have no idea why or how this was happening, but it did.
Maybe this helps,

Hey again,
So we have looked at the problem in more depth, and it seems that it
goes wrong
the first time a home interface is used.
The lookup works fine, but the first time a home is used it gives a(seemingly)
random exception. The second time however it works fine.
Would anybody have an idea ? Thanks,
