All,
I've written about this before, but so far no one has responded to offer any suggestions. So, here goes again.
My problem is simply put: When I try to use localization with displaytag, I encounter problems with redeploying to my jboss.
Basically, I have a web application running inside JBoss 4.0.1 sp1. The web app uses the displaytag library.
When I'm *not* using any of the i18n adapters specified through displaytag (via the properties file), I can deploy and redeploy my EAR file at will.
However, when I set locale.provider=org.displaytag.localization.I18nStrutsAdapter in the displaytag.properties file, I can get the localization to work. BUT, if I then redeploy the EAR file (because I've made another change, for example), the server explodes with a stacktrace when the i18n resource adapter is caled. Here's the stack trace:
17:04:23,688 ERROR [Engine] ApplicationDispatcher[] Servlet.service() for servle
t jsp threw exception

.java:324)
To me, it looks as if somehow displaytag is holding onto some class reference across redeployments of the EAR file.
Note that I can get rid of the classcastexception by bouncing the server, but this is no acceptable in a development environment. Also note that I am perfectly happy to look for problems in our own deployment scripts, but to me, this looks like some kind of displaytag problem.
Can someone help or at least point me in the right direction?
Thanks
