hey there,

my problem is the following. I had a project hierachy that has looked like this:

projects (the root for my packages)
|
daisy
|
examples
|
todo
|
|- <...>.java
|- <...>.class
|-Task.java
|-Task.hbm.xml
|- and so on

no i changed my hierachy to this:

projects (the root for my packages)
|
daisy
|
examples
|
todo
| - dom
| |-some java files
| |-Task.java
| |-Task.hbm.xml
|
| - ui
| | - some UI java files
|
| - other subpackages

Before i had changed the hierachy hibernate works well, but now with the new one i get an exception when starting my program. Some problems by reading the Task.hbm.xml file. Does anybody know what i have made wrong by changing my hierachy? I have not changed the Task.hbm.xml mapping file.

Thanks in advance
