How do I call an external java libray from forms 10g running on Solaris.

We have a forms 10g application that calls an address validation program. We use java to integrate the applications. We have succesfully intergrated the two under a windows environment, however we cannot seem to get the address application to work under solaris.

We have simply added the jar file (including full path) from the address software to the CLASSPATH variable within the Oracle Apps environment in windows.

We transferred the form to Solaris and recompiled it with no errors. However, when run the form on the Solaris Apps Server we get an error. The address application works standalone.

basically, from the piece of code below manager is returning null.

manager := ADTManager.getManagerConnection(0,5000);
IF ORA_JAVA.IS_NULL(manager) THEN
    lp_err_alert(....)
