Hello, 

I wanted to create a ddl file using hibernate. This already works a charme when I let hibernate create my database directly by configuring the hibernate.hbm2ddl.auto in the persistence.xml. But I also need those ddl statements in a file.
Surprisingly there is no simple property to add to the persistence.xml like there is for EclipseLink. 

Searching for the simplest solution to get this done I installed hibernate tools for Eclipse (using the update site). But right after restarting Eclipse it is complaining about a class that it can not find: 
java.lang.NoClassDefFoundError: org/jboss/tools/common/java/IJavaMemberReference

This is the first of a series of errors that come up. (I think the other ones are susequent to this first one.)

The message in eclipse is: 
Problems occurred when invoking code from plug-in: "org.eclipse.core.resources".

Attached is the complete Stacktrace in a text file. 

Does anyone have a hint for me what could be wrong or what I could check?
Googling for this error or for the class IJavaMemberReference did not reveal much.
