Oracle AppModule Error when run

I got an error when trying to test a AppModule that i already set up using the integratedWeblogicServer. i got a error pop up from the JDEV, the error code is like this :

(oracle.jbo.ConfigException) JBO-33001: Configuration file /tester.xcfg is not found in the classpath.

and the error code from the console is like this :


MDS-01370: MetadataStore configuration for metadata-store-usage "mstore-usage_1" is invalid.  
MDS-01368: Variable "oracle.home" used in configuration document is not defined either as system property or as envrionment variable.

oracle.mds.config.MDSConfigurationException: MDS-01330: unable to load MDS configuration document  
MDS-01329: unable to load element "persistence-config"
MDS-01370: MetadataStore configuration for metadata-store-usage "mstore-usage_1" is invalid.  
MDS-01368: Variable "oracle.home" used in configuration document is not defined either as system property or as envrionment variable.

trying to google the solution and find an interest one. try to set up your ORACLE.HOME environment variable. and point it to your <JDEV> folder. Remember to restart your JDEV before you test it.

voila, the AppModule should be run succesfully now !
