I'm having the same problem others have had, yet none of the fixes seem to
work. I'm running an installation that worked just fine on Win2K Server,
JDK1.3.1, and Tomcat 2.1. When I upgraded to JDK1.4 I started getting:
java.lang.ClassNotFoundException: com/sun/xml/parser/Parser
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Unknown Source)
at org.xml.sax.helpers.ParserFactory.makeParser(Unknown Source)
at org.apache.tomcat.util.xml.XmlMapper.readXml(XmlMapper.java:191)
at org.apache.tomcat.startup.Tomcat.execute(Tomcat.java:143)
at org.apache.tomcat.startup.Tomcat.main(Tomcat.java:163)
FATAL: configuration error
java.lang.Exception: Error creating sax parser
at org.apache.tomcat.util.xml.XmlMapper.readXml(XmlMapper.java:207)
at org.apache.tomcat.startup.Tomcat.execute(Tomcat.java:143)
at org.apache.tomcat.startup.Tomcat.main(Tomcat.java:163)
None of the .jar files has been moved from the TOMCAT_HOME\lib directory,
and this worked fine before. In particular, I have xml.jar in the classpath,
which has the requested com/sun/xml/parser/Parser class in it. After reading
the archived newsgroups I tried:
1. adding a parser.jar file to TOMCAT_HOME\lib
2. checking all other .jar's in the classpath for a conflict on the
Parser.class file
3. moving xml.jar to the JAVA_HOME/lib/ext directory
Nothing seems to help. Anyone have a good idea, other than just returning to
the old JDK version? Any hints greatly appreciated.
