The exception is most likely occurring because 'body' is null. Simply
try performing a check against 'null' before operating on it, as in
if (body != null)
sp.append(body.getString());
I'm also not sure what the tag's supposed to do, but it's likely that
you're handling 'sb' incorrectly as well, and that you really mean to
reinitialize it in doStartTag(), not merely to clear it in release(). See
the guidelines I've written at
http://jakarta.apache.org/taglibs/guidelines
for information on properly managing tag-handler state.
