Java Development Tools

Hi All,
I am using the Jdeveloper version 12.1.2.0.0
I have created a common workspace for my ADF enterprise application in Jdeveloper. This common workspace contains a project which will be used in all my subsystems by exporting its JAR file.
This common project contains a package name "framework" in which I have defined a class ApplicationModuleImpl that overrides ApplicationModuleImpl class from oracle.jbo.server. package

After this, I changed the base class in preferences to take my overridden class and not the default class of oracle.

I initialized the project, created the deployment profile for my common workspace project, and exported its JAR file.

Then I created a new subsystem application and added this JAR file to my new model project
But by mistake, I misspelled the package (instead of "dmcsol" I used "dmsol") name in my common workspace.
I corrected the package name in my common workspace, deployed it again and in preference and re-attached the JAR files.
But when I am running application Module Tester in my new module project it's giving me classNotFoundException my incorrect package name.
Kindly help me on this
Thanks
Shoaib
