Hi, Bhogi!

You have to add the files logging.jar, jdo.jar & sapjdoutil.jar out of your NWDS-plugin-folder to your classpath - e.g. copy it in <SDK_HOME>/jre/lib/ext in order to get the JDO build done.

Hi, Bhogi!

In your Employee.jdo-file replace the DTD-reference "jdo.dtd" with "file:/javax/jdo/jdo.dtd".
