Cause

When enabling WFS for a feature service, the WFS connector requires the Java XSLT processor. The error occurs because this processor is not included with Tomcat 5, specifically Tomcat 5.0.28 and some newer versions.

Workaround

1. Stop the ArcIMS services in the following order:
   a. ArcIMS Tasker
   b. ArcIMS Monitor
   c. ArcIMS Application Server
   
2. Stop the Tomcat service.

   http://ftp.wayne.edu/apache/xml/xalan-j/xalan-j_2_7_0-bin.zip
4. Extract the downloaded file to a temporary location.
5. Copy the following extracted files from the folder /xalan-j_2_7_0 (in the temporary location) into <Tomcat_Installation_Dir>/common/lib/.
   · serializer.jar
   · xalan.jar
   · xml-apis.jar
   · xercesImpl.jar
   
6. Copy the extracted files
   xml-apis.jar and
   xercesImpl.jar from the folder /xalan-j_2_7_0 (in the temporary location) into <Tomcat_Installation_Dir>/common/endorsed/.
