Well, I had to go through all my webapplications on one machine and replace any external references to the dtd with localized copies, somehow, I got the one machine running again by doing this, the second machine, I went through and did this again, but instead of the server coming up with the webapplications loading properly, I got this error instead.
These are tomcat4-4.1.27-2jpp rpm's running on Redhat 7.3 with Apache 1.3
The dependencies from JPackage are such that the servlet api gets installed independnently of tomcat4 using
servletapi4-4.0.4-3jpp
bash-2.05a# rpm -ql servletapi4 /usr/share/doc/servletapi4-4.0.4 /usr/share/doc/servletapi4-4.0.4/LICENSE /usr/share/doc/servletapi4-4.0.4/README.txt /usr/share/java/servletapi4-4.0.4.jar /usr/share/java/servletapi4.jar
My thinking that it has something to do with the DTD came from
at >> org.apache.xerces.parsers.DTDConfiguration.parse(DTDConfiguration.java: >> 593)
Which suggested to me that it was being mischevious and somehow throwing the java.lang.NoClassDefFoundError after attempting to do something with the digester, something which required the validation of a DTD before determining the name of a class?
I could be crazy, but these machines were running fine before sun went down today. I even have one running which I'm afraid to restart because I might loose it on reload.

hi mark
a couple of observations that makes me think that perhaps you're on the wrong track:
1. AFAIK tomcat uses an internal catalog version of the standard sun DTDs and so providing that the DOCTYPE description is correct, the parser should not attempt to retrieve the DTD from the DOCTYPE uri. (perhaps craig or Jean-Francois will be able to give a more authoritative statement about tomcat.)
2. the stack trace looks strange (for a DTD uri issue). the exception seem to concern a j2ee class (ServletException) that appears to be missing from the classpath. (if it were a DTD loading issue then i'd expect to see an io-related exception thrown.)

I'm noticing difficulty in starting up my tomcat servers, that seems to arise in the digester. I suspect this is caused by the digester having difficulty acquiring the dtd due to the Sun site being down? Does anyone have any tips on localizing the the dtd referenced here?
