Java problem with Eclipse

[Tom_Towle@bcbsil.com]

error when running Eclipse to do docbook build. I can run this build file
fine from IBMs Rad7 but cannot run it on Eclipse (they should be similiar
and I have them running from the JRE.
Any thoughts as to why I am having this error?.
Buildfile: C:\eclipse_xmldocs\Eclipse_xmldocs\EASFrameworkDocs
\buildhtml.xml
init:
generate-services:
     [echo] Generating services
     [java] java.lang.NoClassDefFoundError: org/apache/xalan/xslt/Process
     [java] Exception in thread "main"
