[Actionframework-users] error while trying to use webmacro

[<bm...@ho...>]

hi.
we have continued using actionframework with velocity with no problems, =
but the thing is that now we want to use webmacro. so, I changed the the =
initparam ActionEngine to 'Webmacro' but become the following error:

java.lang.NoSuchMethodError: =

(I added the webmacro's jar to the classpath correctly)

thx in advance.
