I am trying to install Apache Cocoon 2.1.4 on Redhat AS3.  I have a
jdk installed and also have Apache Ant installed.  When I run build.sh
(as per the installation instructions) I get the following:

[root@INTRAWEB-01 cocoon]# ./build.sh

Apache Cocoon Build System
--------------------------
Exception in thread "main" java.lang.NoClassDefFoundError:

Hi,

That error message means that Java cannot find a library it needs.

Have you followed these steps from the Cocoon installation?

"Cocoon requires more recent versions of the Xerces and Xalan
libraries than those shipped with j2se 1.4. To override bundled
libraries, follow these steps:

   1. Create %JAVA_HOME%\jre\lib\endorsed directory. (Tomcat users use
%TOMCAT_HOME\common\endorsed instead)
   2. Copy xercesXXX.jar, xalan-XXX.jar, and the xml-apis.jar from the
.\lib\endorsed\ to the new directory created above."

If you have done that and it still doesn't work, please have a look
here on how to configure Ant correctly:

http://ant.apache.org/manual/install.html#installing
http://ant.apache.org/manual/install.html#librarydependencies

That error message means that something is missing from your classpath.

Thanks.
