xalan.jar was missing from the build script. I fixed this, this is in CVS.
You need to add xalan.jar to your classpath
Thanks for the quick reply! I really appreciate it.
I added the JAR file in the c:\eclipse\plugins\org.apache.xalan_2.6.0\xalan.jar, but still get the error both from the command line running ant as well as from within eclipse running 'build project'.
I also tried the xalan.jar from the alpha-src/tools/lib with the same error.
I'm missing something....
OK. There may be a better/different way to get this to work, but I got it to compile by pasting my CLASSPATH variable string into the 'value=' clause in the definition of classpath in the default.ent file.
I am posting this in case someone else has the same issue.
