Deployment of CMP Entity bean
Dear all,
I am just trying to get my first CMP entitiy bean going, but I have problems with the deployment. I am using the Sun appliaction server and set up the bean using the wizard. However, when I try to deploy the bean, I get the following error:
"No cmp field defined for CMP EJB SupplierBean".
I have a hunch that the reason might be that I haven't managed to replace the existing deployment descriptor ejb-jar.xml with my own one, because the existing one can't be deleted.
Any ideas?
Cheers,
N.

Post your deployment descriptor.
Here it is:

><prim-key-class>Integer</prim-key-class>You would need a <primkey-field> to be defined too, since you are using a single-field key.I'm not sure if this is the cause for the exception.
OK, I see. So, once I have made the change, how to get the deployment descriptor back into the entity bean?Cheers, N.

I am probably missing something really obvious here, but I am stuck. Using the deployment tool, I don't seem to have any possibility overwriting the existing ejb-jar file. I was also thinking, that the problem could be related to the fact that I haven't specified the CMP resource, yet, because I am not sure about the JNDI name of my MySQL installation. Could this be the problem?

Just a little update here: I opened the jar file now as a zip file and manually replaced hte existing ejb-jar.xml with my own. This seems to have worked - at least I get a different error message, from which I conclude that I have some progrees (if that's what you wanna call it). The new error message is a classNotFound exception. However, I have no idea what class the deployment tool is looking for. Here is the complete message and the log file exerpt. Sorry about the long message, but perhaps some can make something of this. Any help is greatly appreciated!
Best regards,

I managed to solve this problem now. It seems the underlying cause was an incompatiblity between the J2ee stuff I was usgin and the actual Java compiler. I was 1.5 for compiling the code and it didn't work. Then someone gave me a hint and I tried to compile with 1.4.2 and the deployment worked like a charme.
