[Design of Clustering on JBoss (Clusters/JBoss)] - Re: JBAS-4228 Preferred master node for HASingleton

Extending HASEPS lets us have the simple added feature of that class. anonymous wrote : | 2.- Does PreferredMasterElectionPolicy need an MBean interface?

Changing a string attribute is a lot simple to support via tools vs. having to plug in a new polcy instance.

[Design of POJO Server] - Re: Facelets scanning for .taglib.xml is broken in trunk

by alesj

Yeah! Got it working. :-) Hacked the Facelets. I didn't go into even bigger torture, and I simply implemented search on top of VFS.

[Design of POJO Server] - Re: Classloader problem with NamingRestartUnitTestCase

by bstansberry＠jboss.com

I need to understand why native method Class.forName0() ends up calling into the old BaseClassLoader for the naming-restart sar. First thing I want to do is see what the TCCL is when WebCL is trying to create the instance.

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: JBAS-4228 Preferred master node for HASingleton

by galder.zamarreno＠jboss.com

OK, no probs. Thanks for the heads up. Had a quick look at implementing JBAS-5161 the other day and there're a couple of things I wanted to mention: 1.- The intention of JBAS-4228, according to the JIRA, is that if a preferred master is there, use it, otherwise fall back on standard policy. The standard policy imo is the policy that should be applied when no election policies defined, which is, as per HASingletonSupport.partitionTopologyChanged(), : isElectedNewMaster = isDRMMasterReplica(); So, I think we should have a default policy with this implemented and have PreferredMasterElectionPolicy extend it. The current implementation has the preferred master code included HASingletonElectionPolicyBase and if not defined, defaults on the abstract implementation of elect(). So, in reality is doing, if preferred master not available, leave it the election policy defined (for example, in the tests HASingletonElectionPolicySimple). Personally, I'm more inclined to implementing the default policy in HASingletonElectionPolicyBase and PMEP extending it. Thoughts? 2.- Does PreferredMasterElectionPolicy need an MBean interface? We had a chat about this stuff in a previous forum post. I don't think there's a need to have an MBean interface at this level. If anyone wants to check or change this at runtime, this could be done via HASingletonSupportMBean.set/getElectionPolicy() bearing in mind that HASingletonControllerMBean extends HASingletonSupportMBean.

So if I run in between: | build one-test -Dtest=org.jboss.test.naming.test.NamingRestartUnitTestCase | ...the iiop-tests fail afterwards :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4127539#4127539 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4127539

[Design of POJO Server] - Re: Classloader problem with NamingRestartUnitTestCase

by dimitris＠jboss.org

Yes, they pass, e.g. with 'build tests-iiop', even if I run them multiple times. But it fails on the full testsuite run on Hudson. If you look at the stacktrace, its asking the wrong classloader that points to 'naming-restart.sar' which is unreleated with the test.

[Design of JBoss jBPM] - Upgrading GPD

by msandoz

Hi All, We are upgrading the version of the GPD (currently our designer is based on the September 1, 2007 version of GPD cvs trunk) that is used in our nexusBPM extended designer. We've seen several branches in JIRA and were wondering the following: 1. Is this a good time to upgrade or should we wait for 3.2.0? 2. If this is a good time to upgrade, which branch should we pick? 3.1.2 looks like the choice. Is that correct? 3. If we upgrade to either, is there a minimum engine version that is needed due to xsd versions etc. Thanks.
