Tomcat and JAVA: No Class Def Found Error.

[Jose Rodz]

I implemented a Java Servlet to read data from a XML file. I am using Tomcat
4.0.1. When I am trying to execute the servlet it gave me the following error:

"java.lang.NoClassDefFoundError:com/sun/xml/tree/XmlDocument"

I have the same servlet implemented as Java Application and it runs properly.
But the servlet version using the same functions does not.

Can anyone help me on this? Thanks in advance.

please try this

On Windows systems, if you have installed the JDK or Java 2 SDK in D:\java:
C:\> set PATH=D:\java\bin;%PATH%
C:\> set JAVA_HOME=D:\java

Thanks...
I don't have problem with the other java classes. The PATH and JAVA HOME
variables are correctly set. The problem is with XMLDocument class that is
not standard class of JDK. This class is part of the XML.JAR file that I
downloaded. I set the CLASSPATH to include this JAR file and as a Java Standalone
Application it works properly. But when I implemented the class as a Servlet
it gave the error. In my opinion is that Tomcat does not have the path for
this JAR file. How I can define this path? Or where I can put the JAR file
so can it be accessed by Tomcat. Thanks in advance
