I mentioned saxpath.jar in my previous message.

Tomcat marks the context as unavailable which leads me to believe that
Tomcat already has a saxpath.jar available to it from somewhere and the new one is causing a conflict.

Still not working.
If I only have jstl.jar and standard.jar in my lib directory then I
get this error message:
org.apache.jasper.JasperException: org/saxpath/SAXPathException
        at org.apache.jasper.servlet.JspServletWrapper.service(Unknown
Source)
        at org.apache.jasper.servlet.JspServlet.serviceJspFile(Unknown
Source)
        at org.apache.jasper.servlet.JspServlet.service(Unknown Source)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java)
        ...
        ...
        ...
If I put saxpath.jar in my lib directory then Tomcat marks the context
as unavailable.

If I put xercesImpl.jar in the lib directory then Tomcat hangs and leave a process running that I can only kill by restarting my machine (Redhat 9).

I have tried other combinations of jar files in the lib directory also

but get similar results.

I am using Tomcat 4.1.24.

Any suggestions?

Thanks,

If you use the latest Tomcat 5.0.19 and 1.4.2x java, you don't really
need any, but if you are using older versions, then try these for
starters:
jaxp-api.jar
dom.jar
sax.jar
xercesImpl.jar
Then if it seems to work, but complains about a missing class, you can
look for the missing class and add the necessary jar.

Subject: Which jar file supports the XML tld?
There are several JAR files with the JSTL distribution. If i just drop them all into my lib directory then Tomcat complains and marks the context as invalid.

So, which jar files are required to get started with XML?

Thank,
