I have a Jsp custom tag (code below).  When the tag is called i get an error saying that the class:
 javax.xml.transform.Source cannot be found.

in the WEB-APPS/myapp/WEB-INF/lib directory i have xalan.jar xml-apis.jar xerces.jar and xercesImpl.jar

what else is it looking for?  could there be a conflict? am i missing something?

 If it can find the rest fo the classes in the package (e.g. javax.xml.transform.Result) and not the Source class this means that you might be using an older version of the jar file. If it cannot find all of the specific classes in the package then this means that it cannot find the jar file. I would suggest you extract all the jar file's content's under the WEB-INF/lib folder or specify the path to explicitly look at each jar file.

  Hope it helps.

 It is probably a classpath problem but it is difficult to say without seeing your whole environment. Try to put manually all the jar file and class subdirectories into your classpath and try again... Apart from this I do not know what else I could think of...

Thanks for the comment.  As it turns out I just grabbed the latest JAXP jars from javasoft and everything worked fine.  I am still a bit stumped though because everything was running fine under Tomcat 4.0.1.

 I guess every new release of a web server/Sevrlet engine has a bit different way to deal with loading the appropriate classes.

I have this problem, i solve it installing an replacing that .jar files for JAXP .jar files.
This jar files must be in the CLASSPATH
You can download JAXP from sun site.

Seems that updating with a newer version of the jar files did the trick.
