Subject Newbie: help!
Date Fri, 01 Mar 2002 11:32:30 GMT
Although a cocoon newbie, also a human being in need for help getting this
thing started:
I am trying to install c2.01 on Tomcat4.02, Win2k, JDK1.3.
I installed the cocoon war file but when trying to access the main page
(localhost:8080/cocoon) it generates the following exception:

* javax.servlet.ServletException: Servlet.init() for servlet Cocoon2 threw
exception
* blah blah blah...
* root cause
* java.lang.NoClassDefFoundError: javax/xml/transform/URIResolver
* blah blah blah...

So I bundled all the javax.xml.transform classes from Sun's XML Pack Winter
Release(JAXP) and put them in Tomcat's common lib, which gave me the
following exception:
* The sitemap handler's sitemap is not available. Please check logs for the
exact error.
Importing the entire JAXP package made no difference. same error message.

I checked installation & online docs, with no luck.
zm.

Thanks, I'll try it out.

This is another strange thing.  There is 512M, but top only shows 64M...I
think that I should update top

OK, I'll use this config.

I will try it out. Thanks again!
