If you configure WebSphere and deploy SAS Web applications to the server manually, you might see the following error in the WebSphere Systemout.log file:

This error indicates that a class-loader setting is not set correctly for the SAS Web applications. To resolve this issue, update the setting to PARENT_LAST as explained in the following steps. Note: You can also find these steps in the Instructions.html file.

Updating the Class-Loader Setting

To solve this problem, you must update the Classloading policy and mode for the EAR file and the Classloader mode for each WAR module that is contained in the EAR file. To do this:

1. Select SAS_Web_Infrastructure_Platform_Services from the Enterprise Applications menu in the WebSphere Application Server's administrative console.
2. Click the Classloading policy and update the detection link for the application EAR file. Also, ensure that the Classes loaded with application class loader first radio button is selected for this EAR. Note: By default, the WAR Classloading policy at the EAR level is set to a value of MULTIPLE, so no action is required.
3. On the Enterprise Applications page for this application, click the Manage Modules link.
4. You now must select each individual WAR module and use the Class-loader order menu to set Classes loaded with application class loader first, which is the same as setting a value of PARENT_LAST). Then click OK.

   Note: You can wait until all of the WAR module Classloader modes are set to PARENT_LAST before saving your work.
