Common lib jar configuration for fusion web project

Question

Hi,
I have one common lib jar file which contains webservice proxy client.
I have multiple fusion web projects which contain bounded taskflows. These projects are exposed as ADF lib jars and used in webcenter pages.
Each fusion web projects contains model project and which defines one java class as application module. The application module calls webservice proxy client for supplying data to UI layer.
I am looking for clarification on adding common lib jar to fusion webprojects. Do I need to add common lib jar file for both model and viewcontroller project? Is there any way to add at fusion web application level so that both model and view controller projects can refer the lib jar and also for Webcenter application if I add this taskflow as region to the page.

Hi,
Do I need to add common lib jar file for both model and viewcontroller project?
This really depends on your architecture. If for example the ADF model you reference in the view layer project is from an ADF Library too then the view layer project needs to have all the library references. If the view layer project is in a workspace with a model project and the model project is the client of the service then the common jar files need to go into the model layer.
and also for Webcenter application if I add this taskflow as region to the page.
If you use it in a region then the problem is that ADF libraries don't hold 3rd party JAR references, which means you need to provide the library to the consuming application of the task flow. You can try configuring the JAR file in the EAR file you deploy with your consuming application and see if this is enough. Otherwise you can try a shared WLS library deployment
