[Design of JBossCache] - Serialization Compatibility Tests

by ryan.campbell＠jboss.com

This is a discussion about http://jira.jboss.com/jira/browse/JBQA-536. I'd like to give some background for JBC developers to catch up on what we are trying to do. We would like to ensure backwards compatibility of serialized objects between two different versions of JBossCache. To do this, we have selected the SerialVersionUIDUnitTestCase from the JBossAS test suite as the basis for our test. SerializationUIDUTC compares the serialization UID's between a database of serialized classes (representing a previous version) and the current classes on the classpath. There is a utility in varia for creating the database for a given version. So the task is to create a derivative of SerializationUIDUTC which does the same for JBossCache. One outstanding question is should the test compare both explicit and implicit serialVersionUID's? Or just implict?

[Design of JBoss Portal] - Persistent producer registration impl

by julien＠jboss.com

I am starting to implementation of the producer registration in the core module based on hibernate. I don't understand the logic in RegistrationManagerImpl#createConsumer(String name) and RegistrationManagerImpl #addConsumerToGroupNamed(String consumerName, String groupName, ...) In createConsumer: 1/ a consumer is created 2/ its name is used to to retrieve a group then the created consumer is never used anymore. I see that the method is calling public Consumer addConsumerToGroupNamed(String consumerName, String groupName, boolean createGroupIfNeeded, boolean createConsumerIfNeeded) with addConsumerToGroupNamed(groupName, groupName, true, false); I have a few comments on that : 1/ perhaps it should be consumer.getName() as first argument 2/ is the method addConsumerToGroupNamed able to retrieve the same consumer from only its name and not its id, or do we have an effective dual creation of a consumer ? | String identity = policy.getConsumerIdFrom(consumerName, Collections.EMPTY_MAP)); | I would have rather simply seen : addConsumerToGroupNamed(consumer, groupName, true, false); I would go even further by adding that constraint in the persistence manager and instead of having the sequence : 1/ create consumer 2/ associate it with a consumer group change Consumer createConsumer(String id, String name) throws RegistrationException; to Consumer createConsumer(ConsumerGroup consumerGroup, String id, String name) throws RegistrationException; to enforce by construction the fact that a consumer is attached to a group.

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: JBAS-3864 Discussion Thread

by bstansberry＠jboss.com

We accept breaking compatibility at a major release. We don't want to go crazy introducing incompatible stuff, because that does make upgrading harder. But, on the other hand, it's good to be able to use a major release to clean out old ways of doing things. With snaphsot mode, it's borderline. The benefit of removing it from the Tomcat SAR config is not that great; mostly it just removes from the xml a bunch of complicated explanation of a feature people don't use. It also reduces coupling between the depployer and the webapp (less data needs to get passed into the webapp.) But some data (useJK) still needs to get passed, so the decoupling benefit isn't that great. I'm inclined to remove it from the sar mostly because I don't think it's used. For example, I've never seen a forum post related to the behavior of "interval" snapshot mode.

[Design of Kosmos] - Re: Deploy failure on Liferay

by philipkerrigan

Thanks for the pointer bjoy, but that file is almost exactly the same as the deploy file provided with KOSMOS. The only difference is the optional flag which I added, but it makes no difference. I still get the error [java] java.lang.NoClassDefFoundError: com/liferay/portal/tools/PortletDeployer I am deploying on Windows XP, with Liferay 4.1.3 anf Tomcat 5.17 (I had to downgrade because of a Tomcat problem with context loading) and JVM 1.5. At a guess I would say my classpath is not set correctly, although the deployer may have changed. Since I don't know where it should be found I don't know what to change. Any idea where to look next?

[Javassist development Forum] - Illegal class modifiers

by wessan

Hi, I have already tried this in user forum, but I got no answer. I'm getting java.lang.ClassFormatError: Illegal class modifiers in class test/app1/EmployeeImpl: 0x431. This exception is thrown when using custom ClassLoader and calling defineClass method. I don't change the modifiers of the class in any way, but the rest of the class may be altered. Is this a known problem, or am I doing something wrong? Thanks for help.

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: JBAS-3864 Discussion Thread

by igarashit

I almost agree with you. Only thing I am warrying about is compatibility. But it seems to depend on JBoss versioning policy, so if you say no problem, then it's OK :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3992414#3992414 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3992414
