Name and version of the database you are using: MSDE with Microsoft JDBC

The package lipman.ncc.hibernate.RconsistId exists, compiled and persists in the same place as the other classfiles.

This error occurs when I try to create Session from IDE.

Notes.
1. When I add ncchib project as classpath to console it causes a NullPointerException(no message)
2. When I export .class files to jar and add this jar to classpath the exception is

Add the directory location of your compiled .class files to the console - not the project.

Just in case: add the location of your db driver in the console too.

Hope this helps.

Yes, it helps to move forward.
But looks like I cannot add the directory from Eclipse, the only way is to close Eclipse and edit console.xml manually.
Am I right?

Editing the console.xml manually sounds painful :-)...

If you're in the Hibernate Console view, you can create or edit an existing configuration. Either case, you'll get the "Create Hibernate Console Configuration" dialog box.

Near the bottom half click button labeled "Add Jar/Dir...". From here you can add what you need to the classpath.

Hope this helps.

Yes, but what I see in the tree view is projects tree, not file one.

Click the + sign next to the project you're referencing, then navigate to the directory you need and click OK.

It doesn't work this way.
it only works when I change console.xml manually.
