Hi,
I have an old app which was developed under struts 1.2.8 using struts-
tiles, and has undergone steady development.
However, /AS FAR AS I KNOW/, no changes to the tags library files
have been made for a long time.
Yet today, after rebuilding the project (using Project > Clean in
Eclipse), I suddenly am getting this exception:
java.lang.ClassCastException: org.apache.struts.taglib.html.MessagesTei
(The full exception is shown at the end of this message) I don't
recall ever seeing this before, and am not sure what to do to solve
the problem.
I'll greatly appreciate any suggestions anyone can offer.
Thanks in advance,
Ken Bowen
