In WLP 10.3.2, the datasync web application has been deprecated. This makes sense if you consider the recommended approach is to test all of your Datasync Project work in DEV mode and then propagate up once you have everything the way you want. However, if you are upgrading or have a development process where this is not the easiest policy to implement, you may wish to bring back the datasync.war. If that is you, fear not! Blogging to the rescue!
While in previous versions of WLP it was automatically added to a portal EAR project, in 10.3.2 you must manually add the dataync.war.
The documented approach (How To Import and Add the Deprecated ‘Datasync.war’ to the WebLogic Portal Application (Doc ID 1268447.1)) to add it is to use OEPE, right-click on the EAR project, select Import War, and import [WLP_HOME]p13ndeprecatedlibdatasync.war. Doing so creates a datasync project in your workspace.
The documentation goes on to describe an edit to the MANIFEST.MF to include the classes from ImportedClasses on the classpath. When I tried it, I could get to the data sync application index page, but would get a 500 error past that.
Digging through the logs, I found class not found exceptions. I eventually fixed this by moving the jsp folder under/datasync/ImportedClasses/WEB-INF/classes/com/bea/p13n/management/data to /datasync/ImportedClasses/com/bea/p13n/management/data, re-building and re-deploying.
