<p>But why exactly do you need to change classloader before dispatch?</p>
<p>I must admit I don't see a valid reason, but it's true it's been a while since I did web apps ...</p></blockquote><p>Well, the whole history then.. I'm doing a portlet that is a dynamic Portlet Bridge. It can be configured to show any existing web app deployed along with it in the same JBoss. That's for the dispatch.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>For that I need to "inject" JBoss Portlet Bridge libs/classes/configs in the application's classpath, so everything loaded by application should look also in the container's classpath. That's for the delegation.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The problem is as described in my first post, I can't do an actually delegation.. Today I got it working by moving some jars to $JBOSS_CONF/lib which obviously isn't a good solution.</p></blockquote><p>I see.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I guess you could somehow super hack it with your approach -- changing the TCCL,</p><p>but that's not the way it should be done. ;-)</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Why it doesn't work in JBossAS by default is b/c each .war is placed into its own domain, which then gets child-first lookup notion.</p><p>So, all you need to do in order to make this work is for all web apps that you want them to share resources to be in the same domain.</p><p>Which is why your jar move makes this work -- the common resources can be fund in common default domain.</p><blockquote class="jive-quote">I've been talking to Wesley Hales from JBoss Portlet Bridge too, maybe he can give you some insight (I believe you don't mess with portlets a lot <span> ;) </span>)</blockquote><p>Well, I'm sharing an office with Marko (JBoss Portal core dev), so why don't the three of you decide what exactly you need to achieve,</p><p>and I'll make sure Marko makes that a reality with MC's CL, instead of us two playing forums ping-pong.</p></div>
