NoSuchMethodErrors often occur when you have the wrong version of a library
on your class path. This happens because your code is looking for one
version, that has method X while the library you've included has a
different version without method X.
I don't know a lot about WebSphere, but I do recall that it ships with an
older set of libraries and that it prefers those libraries (it calls this
parent first) over ones in the application (it calls this parent last).
I've seen cases where switching to "parent last" mode has resolved similar
issues.
If that doesn't help, I second André's suggestion to look for help in a
more appropriate forum.
