Hibernate Console cannot find Entity despite it being on CP

Hi,

hopefully somebody of you can help me with this problem that is bugging me and driving me insane.

I have a Spring/Hibernate application based on Appfuse and I would like to prototype HQL statements in Eclipse using Hibernate Tools. When trying to create a Hibernate Console configuration, I can add the properties to my Oracle Database and my mapping files without problems. I then want to continue add the dao.jar and ojdbc.jar files to the classpath (POJOs + JDBC driver).

After saving my configuration I can see the tables in the console view and the mapping files without problems. But then I try to open the sessionfactory for the HQL Editor, I am confronted with a org.hibernate.MappingException. The root cause is that it cannot find a specific POJO entity class not found: de.fzk.iai.prowida.security.model.User.

The strange thing is, I have added the dao.jar that contains the dao and model classes. It becomes even stranger when I recognized that the console can find half of my entity classes, but some specific classes located in a different folder are not found (starting with the given User POJO). This is how "dao.jar" looks like:

Code:

dao.jar
|
|--META-INF
|
|--de
    |
    |--fzk
        |
        |--iai
            |
            |--prowida
                |
                |--core
                |   |
                |   |--dao
                |   |
                |   |--model
                |        |
                |        |-(POJOs that are found)
                |
                |--security
                |   |
                |   |--dao
                |   |
                |   |--model
                |        |
                |        |-(POJOs that are NOT found, e.g. "User")
                |
                |-- [... base classes, 2 more packages]

And this is the full stacktrace of my eclipse logging file:

Is dao.jar on the console's classpath ?

grandfatha · **Joined:** Thu Aug 23, 2007 5:22 am **Posts:** 3

Yes, that was what I tried at first.

Then I tried to add the "classes" folder of "bin" where all the compiled classes are in the same package/name structure as the source of course.

I tried creating my own jar file with the folders starting from "de.fzk...." just as you would expect it.

Basically I tried anything to help him find my files.

It all did not help.

Edit: Tried it today in RHDS beta1. The Console Configuration Wizard GUI threw a lot of strange exceptions to the Error log like "Ressource \test is not open" or "Unhandled event loop exception".

Code:

The nullpointerexception is a known issue.

The others looks very weird since it indicates that the reason we can't find any classes is because the .launch file is not created correctl....

Could you report this in our jira with the *minimal* steps to reproduce this ? (e.g. on the simplest project possible) ?

thanks
