I am trying to install and test RC1 of Axis, and am getting a mysterious failure in step 5 "Installation testing" of the installation instructions. The validation servlet complains about an internal server error with root cause "java.lang.NoClassDefFoundError: org/w3c/dom/DOMErrorHandler". But I have xercesImpl.jar (from Xerces 2.0.2) in my webapps/axis-rc1/WEB-INF/lib directory (I chose "axis-rc1" as the directory/webapp name for this version of Axis in my local servlet container). I see that org/w3c/dom/DOMErrorHandler.class *is* in xercesImpl.jar. I am using Tomcat 4.0.4, on RedHat Linux 7.1.
Below is more detailed evidence. First, a plain text copy of Netscape's display of the validation page output. Then comes a shell typescript showing that xercesImpl.jar is in place and really does contain org.w3c.dom.DOMErrorHandler (the error message about "no main" comes only after determining that you've got a well-formed class). Thanks for any clues, Mike ==================================================================== Plain text scrape of <http://wat-eu-2:8080/axis-rc1/happyaxis.jsp>: pache Tomcat/4.0.4 - HTTP Status 500
