Fixed our own problem - this may help others:
We needed Tomcat 6 jars to be in $ANT_HOME/lib
Pretty obvious with hindsight, but hindsight is a wonderful thing...

Subject: Release 1.0.0 RC3 - Ant Build Fails with JSP-Compile Error
We have just checked out the latest version of Hadoop source from
http://svn.apache.org/repos/asf/hadoop/common/tags/release-1.0.0-rc3 and we have attempted to build it using the ant build.xml script. However we are getting errors relating to the jsp-compile command.
We are getting the following error when we run "ant" inside our $HADOOP_INSTALL directory.
/opt/hadoop/release-1.0.0-rc3/build.xml:527: jsp-compile doesn't support the "webxml" attribute
Please can you suggest what might be the cause and/or how we can fix this issue, to build Hadoop successfully.
