These files I had when I began working with the OJB. I compiled them and put them in a jar and stuck them on the classpath - no problem. I also put the OJB distribution files on the classpath, as well as all the jars in the lib (all of this using an Ant script). Querying and persisting worked fine. Creating an Identity instance from scratch and passing it to getObjectById() failed, indicating there were no implementors for the Identity interface. If I queried the object first, got the object id, and then passed it to the getObjectById() method, things worked fine. Bringing the entire source into my project fixed the problem. I figure there must have been something missing from the classpath.

Those classes are under src/jdori you have to use the ant target "with-jdori" to copy those java files into the staging area for the preprocess and compile procedure. cheers, Thomas > > -----Original Message----- > From: Mahler Thomas [mailto:[EMAIL PROTECTED] > Sent: Tuesday, April 01, 2003 11:43 PM > To: 'OJB Users List' > Subject: RE: JDO - getObjectById() > > > Hi Shawn, > > > -----Original Message----- > > From: Shawn Vincent [mailto:[EMAIL PROTECTED] > > Sent: Tuesday, April 01, 2003 10:29 PM > > To: 'OJB Users List' > > Subject: RE: JDO - getObjectById() > > > > > > I was able to get it to work by bringing in the soucre and > > compiling it in > > with my project.
