I can't say what the problem was caused by. But by repeatedly
cleaning and recompiling (with no substantive changes), I finally got
it to deploy again (as it has been for months).
Very strange.

Hi,
I've been using Tiles 2.06 in standalone mode in a Tomcat-based
webapp successfully for a number of months. In my development
setup, I redeployed my app today and suddenly got the following

To my knowledge/memory, I have not made any changes in the jars for
many weeks --- but there have been some changes in the structural
organization, i.e., ant, etc.
The tiles jars I have in WEB-INF/lib are:
tiles-api-2.0.6.jar tiles-core-2.0.6.jar tiles-jsp-2.0.6.jar
I'm using Tomcat 6.0.18 with Java 1.5
I'll certainly appreciate any suggestions for what to look for that
has caused this.
Many thanks in advance,
Ken Bowen
