The OJB folks use following snippet in their build file: <condition property="jdo.classes"> <and> <available classname="javax.jdo.PersistenceManager" classpathref="compilation-classpath"/> </and> </condition> <target name="check-jdo-classes" unless="jdo.classes"> <fail>jdo.jar is missing! Please get it from http://java.sun.com/products/jdo. Put it in lib or have the ant property jdo.jars point at this jar file.</fail> </target> I rewrote the example now. I'm really not a OJB expert, nor a database expert. I made this example to learn more about OJB and JDO, and I didn't get the "insert" method work properly. Stephan.
