[Installation, Configuration & DEPLOYMENT] - DeploymentScanner

by HarleyGuy

I am hoping a more senior JBoss expert can share his knowledge on remote deployments to JBoss-AS. We are using JBoss-4.2.3GA. We are using Hudson to accomplish our builds for the web project. We are now attempting to deploy the war file to a remote JBoss-AS running on Redhat Linux. What I discovered is JBoss-AS has the ability to scan a URL and accomplish a hot-deployment for us. We can just drop off the war file in a directory for JBoss to scan. We would have to manually remove the old war file so JBoss-AS will undeploy it for us. The guys on my team are not very supportive on making this work because they want a clean build and suspect JBoss-AS will not provide us with this capability following my approach. Are there any pitfalls with using the Deployment Scanner JXMBean like I described above? Thanks for taking the time to read my post.

The application I'm working on may be installed at a client site where we have no controll over the the App Server. In addition, as you said, changing the endorsed Xerces may lead to other problems so I do not think this is a viable solution. Are you saying that currently there is no solution to this problem? If so, I'd say this is a pretty big issue for JBoss considering this problem is not seen in JBoss 4 and thus constitutes a pretty important change in behavior. Perhaps this should be escalated and/or be given more attention? I've seen numerous posts on the forum complaining about this and none of the workarounds (classloader isolation, removing Xerces from war) address the underlying problem of being able to use a different version of Xerces than the one in the endorsed dir.

[JBoss Portal] - How can I get Edit Mode to default to Maximized Window State

by malmit

I'm trying to figure out a way to get from the standard VIEW mode of a portlet to Maximized EDIT mode by clicking the "Edit" link at the upper right hand corner of the portlet. I tried changing the window state in the doView() but it doesn't look like it is possible. Has anyone had any luck doing this?

So i am not sure whether its an intended behaviour or just a bug in its implementation.

[Installation, Configuration & DEPLOYMENT] - Re: ClassCastException due to Xerces conflict during app dep

by jaikiran

Yes, i did try this out. From what i looked at, the deployment framework starts using the version of xerces jar present in your deployment because it sets the classloader to your deployment's classloader. I think this is the correct thing to do, because each deployment is expected to be started within its own classloader to ensure that it gets access to the right resources. Now the real issue with xerces is that its an endorsed library. i.e. it's part of the Java endorsed library directory. So the only way to override the xerces version appears to be to change the version in the JBoss endorsed directory (but that can lead to other issues). This is where i had left off in my investigation of this issue a while back.

[Installation, Configuration & DEPLOYMENT] - Re: scoped repository not working for apps in alternate depl

by bvallade

I believe I discovered what was happening. The server that I was debugging on was missing the trailing / after the directory name so the entire directory was being treated as a deployment instead of as a dir of sub deployments. thanks, Brandon View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4249294#4249294 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4249294

[JNDI/Naming/Network] - Understand JNDI naming convention

by mohitanchlia

Jboss 4.2: I always have hard time understanding JNDI naming convention. I try to understand one way or the other but next time when I look at them it again leads to more confusing. I have hard time understanding 1. concept of java:/comp compared to mapped-by name. 2. Also what Global JNDI is. 3. When I look in JNDI view of jmx-console I see something like e.cache:service=CacheLoader I don't know what those ":" and "." and "=" are for. How to interpret that whole string. Is it just the unique string or does ".", ":" and "=" have some special meaning.

[Installation, Configuration & DEPLOYMENT] - scoped repository not working for apps in alternate deployme

by bvallade

Hello, I have set up JBoss to scan for deployments in a directory in addition to deploy/: jboss-service.xml: deploy/,fs-deploy/ In my apps I specify the need to use scoped class loading: <jboss-app> <loader-repository>mydomain.com:loader=uniquedeploymentname.ear</loader-repository> </jboss-app> However when I boot JBoss app1 loads all the classes and when app2 loads it finds shared instances of the classes (i.e. shares singletons). When I move app1 and app2 into the deploy dir (standard deployment location) class loading works as expected. What do I need to do to get apps placed in fs-deploy to behave like deploy? I am using JBoss-eap-4.2.0 thanks, Brandon View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4249291#4249291 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4249291
