Java EE (Java Enterprise Edition) General Discussion

Hi, I am just getting started with the J2EE tutorial and I am running into a problem when I try to perform the ant converter line. I receive the error "Exception in thread "main" java.lang.NoClassDefFoundError: xml." It's obvious that I'm missing a class somewhere, but I'm not sure where. I thought I had everything. Here is my classpath:

.;c:\programs\apache\xerces-1_2_3\xerces.jar;c:\wstk-2.3\soap\lib\soap.jar;c:\programs\sun\javamail-1.2\mail.jar;c:\programs\sun\jaf-1.0.1\activation.jar;c:\wstk-2.3\wsdl-toolkit\lib\wsdl.jar;c:\wstk-2.3\lib\xalan.jar;c:\wstk-2.3\lib\bsf.jar;c:\dev\jdk1.4\lib\tools.jar;c:\wstk-2.3\lib\wstk.jar;c:\programs\Servlet2_2\servlet.jar;c:\programs\apache\jakarta-log4j-1.1.3\dist\lib\log4j.jar;%ANT_HOME%\lib\ant.jar;%ANT_HOME%\lib\parser.jar;%ANT_HOME%\lib\jaxp.jar;c:\j2sdkee1.2.1\lib\j2ee.jar

Is there something I'm missing? Thanks.
