I am having a problem generating a Hibernate POJO from a .hbm.xml file. Initially I generated the hbm file from an Oracle database. I then had to modify the hbm file to add some custom tags. Then, when I right click the file and select MyEclipse -> Generate POJOs I get the exception pasted below. This doesn’t happen on all the hbm files, only a few. I have attached working and none working hbm files below.

The only explanation I could come up with is that somehow the class it has a problem with wasn’t registered in the hibernate.cfg.xml file, but all related classes are defined there.

Can you go to Windows > Show View > General > Problem and check if any build path errors are showing up.

I have made sure that there are no build problems. The errors I’m getting are related to other generated Hibernate POJOs. For example, in the exception above, the Campaign class has a problem with the touches Set in that the Touch class cannot be resolved. That class is generated as well. It’s Abstract class failed to build for a similar reason, but the concrete class is definitely in the build path. I even decompiled the class file from the bin folder and it looks fine to me. I tried to clean the project with all the concrete classes there and generate again, but I still get the same problem as before.

Can you create a sample project and send it across so that I can try reproducing this issue at my end as well. You can hit the pm button and at the bottom of my post and send me the project.

In the process of putting together a simple sample, I have figured out what the problem is. I still have no idea how to resolve it, but at least I’ve narrowed it down…

Because I have so many tables, I wanted to group them into several packages. Some of the POJOs reference objects in packages other than their own. For example, the test.employee.Manager object has a set of test.project.Project objects and a set of test.employee.Employee. This causes the “Generate POJOs” menu option to fail. However, if these objects are generated from the database there is no problem. If I remove the set of Project so that the test.employee.Manager object only has a set of test.employee.Employee, this works without a problem. Also, this only seems to be happening on sets, bags, maps etc. If there is a many-to-one reference, it seems to work without a problem.

Unfortunately I don’t have the option generating my POJOs directly from the database because we have too many FKs that don’t need to be in the objects. I really need to have the option of generating a POJO from an hbm file.
