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.

I had a problem the other day where a user that was logged out still had their name showing on the screen. I thought the session wasn’t being invalidated, but it was actually a case of the browser caching the page. Digging around, I found a solution that, when added to a backing file for the desktop to run during pre-render did the trick:

import com.bea.netuix.servlets.controls.content.backing
               .JspBacking;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class NoCacheBacking implements JspBacking

{
   public void dispose(){}
   public boolean handlePostbackData(HttpServletRequest request,
      HttpServletResponse response)
   {

      return false;
   }

   public void init(HttpServletRequest request,
      HttpServletResponse response){}
   public boolean preRender(HttpServletRequest request,
      HttpServletResponse response)
   {
      response.setHeader("Cache-Control" ,
                   "no-cache, must-revalidate");
      response.setHeader("Pragma", "no-cache");
      response.setHeader("Cache-Control","no-store");
      response.setDateHeader ("Expires", 0);

      return false;
   }
}
