Have just upgraded to 3.3 rc1, and get the following occasional message:

Haven't done anything different, so presume this is a bug!

Further investigation reveals that this seems to occur every time tomcat 
compiles a jsp

Comment 2 william.barker 2001-09-28 12:00:42 UTC

Tomcat 3.2x allowed only well-formed web.xml files.  By default, 3.3 requires 
the web.xml to be valid (e.g. all elements must be in the order specified in 
the DTD).  You can disable this by setting validate="false" in the WebXmlReader 
element of server.xml, but I'd recommend fixing the web.xml file (since this is 
the only way to be portable to other containers).

Reopen to mark as fixed.

Comment 4 Costin Manolache 2001-09-28 21:29:16 UTC

Added better messages, and an ErrorHandler.
You can disable validation by settings in WebXmlReader, or fix your xml file.
