I know this is a very specific problem to my configuration but I'm a bit
at a loss to figure out how to get around this error. I have used
Vaadin on quite a few projects quite successfully with Cayenne and this
is the first time I'm using the IcePush module that lets you push
updates to the client. When I add the usual Cayenne filter in the
web.xml file the application fails to deploy with the following error
message which I understand to mean that the cayenne library is not being
located in a timely manner by "something" where the something probably
has to do with the Icepush module. So my question is what do I need to
do to get the Cayenne library loaded before whatever is not finding it
;-) I've tried adding the cayenne-client-3.0.2.jar file to the tomcat
lib directory and to the java jre/lib folder but it doesn't seem to make
a difference.
Any guidance would be appreciated.
Thanks,
Andrew
