I don't think it's your build.xml.  I had a similar problem compiling
at the struts stage.  Middlegen or XDoclet - not sure which - had
generated some code like the following:

    java.math.BigDecimal strands = ...;
  
    java.math.BigDecimal id = new java.math.BigDecimal(strands);

Java, in its infinite wisdom, can't construct a BigDecimal from
another BigDecimal.  Really.  So I hand-edited the code and moved on.
I suggest you might do the same.  That means changing your build.xml
so break the chain of dependencies.  You don't want Middlegen being
run every single time or you'll trash your hand-edited code.

The problem I encountered was already reported on sourceforge.

Cheers,
Gavin
