Configuring a Web project to reference a Java Project.

[dhanya kairali]

I have created a Dynamic Web project in WSAD.
I need to create a java project that this references.
I set the Java Build Path properties of the Web Project to use my Java project. the files in my web project using the java files in my java project compiles.
Now I try to run the Web project - it complains of mising classes.
When I try to export my projecft as a war file the files in my java project are not exported as well.
What have I missed?

WSAD can set build time (class path) references as well as run time references (set in the \WebContent\META-INF\MANIFEST.MF file of the WAR or just META-INF\MANIFEST.MF of JARs).

You need the build time references to COMPILE and the run time references when the server is running and the WAR is deployed in order for the application to USE the specified external projects. The run-time reference is absolutely neccessary else the WAR will report class not found exceptions.

Run-time references to existing projects will not be exported when a WAR is exported. They will, however, exported if they both belong to an EAR and the EAR is exported (they will be separate but both inside the EAR). Else, the only way is to use the java project without exporting the EAR is to manually export the java project into a JAR file first, and then copy it into the WAR's WebContent\WEB-INF\lib directory, the down side being this is a manual step (unless you set up scripts) and will have to be repeated before you build a WAR.

Thanks for the response. This was the solution I was looking for.

I have set up my Java project and my Web project.
I add my Java project to the build path of my web project
I open Manifest.MF and add the Java Project as a dependency for my Web project.
My ear projects application files says it has 2 modules -my Web project and my Java project.
In the Applications tab I set WAR Class loader policy to APPLICATION
Is this correct?
Also what do I need to do after I update a java file in my java project so that the change gets reflected? Do I need to do a project rebuild? Is there a better solution?
Thanks in advance!
