Status: Unverified
FACT(s) (Environment):
OpenEdge 10.1A
SYMPTOM(s):
Class ENamedElement cannot be found when executing Java Open Client
Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/emf/ecore/ENamedElement
The error does not occur when compiling the Java program
The CLASSPATH contains a reference to o4glrt.jar.
CAUSE:
The ENamedElement class belongs to Eclipse. It is provided by the ecore.jar package located in <OpenEdge installation directory>\java\ext.
This Eclipse package is missing in the CLASSPATH.
When deploying an Open Client application that uses a Java proxy, the following third-party Eclipse jar files must also be deployed and included in the CLASSPATH environment variable:
common.jar
commonj.sdo.jar
ecore.jar
ecore.change.jar
ecore.sdo.jar
ecore.resource.jar
ecore.xmi.jar
FIX:
To deploy a client application that uses a Java proxy:
- Copy the Eclipse jar files below in a directory where the Java Open Client Runtime resides.
common.jar
commonj.sdo.jar
ecore.jar
ecore.change.jar
ecore.sdo.jar
ecore.resource.jar
ecore.xmi.jar
- Include those Eclipse jar files in the CLASSPATH variable environment.
Example for Windows:
set CLASSPATH=<Path>\common.jar;<Path>\commonj.sdo.jar;<etc..>
