RE: Finding the XML parser in Tomcat
I think this has come up before. Tomcat has an XML parser built in (it reads XML files for configuration). To use Xerces in our servlets, we had to add xerces.jar to the front of the CLASSPATH in the tomcat.sh script.

Why will it not find the parser in the Tomcat WEB-INF\lib directory? Is this an XML, jdk, Tomcat issue or what? If I add the XML lib to jre\lib\ext, what/how system properties must be set?

Alternatively rename it to _xerces.jar and put it in the $TOMCAT_HOME/lib directory. That way you wont have to change your tomcat.sh cheers dim Eoin. -Original Message- From: Frank Lawlor [mailto:[EMAIL PROTECTED]] Sent: Monday, June 18, 2001 7:20 AM To: Tomcat (E-mail) Subject: Finding the XML parser in Tomcat In my VisualAge Java development environemnt (jdk 1.2.2) I can say, for example, Parser parser = ParserFactory.makeParser(org.apache.xerces.parsers.SAXParser); but when I deploy to a standalone Tomcat environment, I get a class not found on the parser name, even tho I put the jar in Tomcat's WEB-INF\lib directory.
