I have now found out the error that occurs when I try to run the
transformer, it is this:
java.lang.NoSuchMethodError
What does this mean does it mean???? I am confused beacuse if the method
works when not invoked by the servlet then it must be able to find the
methods I have used what could this possibly mean ??
PLEASE HELP...
