Solution or Workaround

Update ServletExec to version 5.0.0.14, which is current as of September, 2007.
The update files can be found at:

New Atlanta's General ServletExec Hotfix Information

Download the appropriate patch based on your operating system and version of ServletExec.

  1. Stop ServletExec; stop IIS (Internet Information Services).
  2. On a typical install, navigate to C:\Program Files\New Atlanta\ServletExec ISAPI\lib. Find and rename ServletExec50.jar to ServletExec50.jar.orig and ServletExecAdmin.jar to ServletExecAdmin.jar.orig.
  3. Unzip the JAR files to the same directory as the ServletExec50.jar.orig and ServletExecAdmin.jar.orig files.
  4. Start IIS and try Metadata Explorer again.
