Re: Newbie needs help with OJB in Eclipse
Hi Doug, This seems like a problem with your build classpath settings in eclipse. Try to load OJB from CVS HEAD with eclipse. In CVS we have the eclipse .project and .claspath files that eclipse needs to build OJB.

Hello everybody, I just got started with OJB and i'm experiencing some problems. Here's the scenario that i'm trying to get to work: A DOCUMENT belongs to 1..n CATEGORY. A DOCUMENT is relevant to 0..n PRODUCT_MODELs. A DOCUMENT is written by 1..1 AUTHOR. D DOCUMENT is described by 1..n KEYWORDs. My first question is: since there are many-to-many relatioships between DOCUMENT and CATEGORY and DOCUMENT and KEYWORDS there are two join tables called DOCUMENT_CATEGORY and DOCUMENTS_KEYWORD. How does one handle join tables needed by many-to-many in OJB? All the data retrieved from the database (MySQL) should be wrapped in ValueObject Classes. Following is the repository_user.xml file that I'm using so far. Every time I'm trying to save object to the datastore or try to retrieve them I get a org.apache.ojb.broker.metadata.ClassNotPersistenceCapableException with the following message: java.util.ArrayList not found in OJB Repository.

I checked usage of 'indirection-table' with the Person <-> Role mapping and
it seems to be exactly like I used it. I can't find any difference

Couldn't find any differences. In junit tests Collections are used. I also
use Collections.

In the following I included the source for all my value objects. I removed
getter/setter methods. I didn't include the repository.xml again.
