[Design of POJO Server] - Re: Dropping http-invoker.sar?

by scott.stark＠jboss.org

Just an FYI followup, this was rolled back last week as there are several tests that depend on the http invoker. These would have to be refactored into a separate http-invoker testsuite config, and its not likely we'll do this for GA.

[Design of JBoss jBPM] - Task lifecycle in jbpm3

by heiko.braun＠jboss.com

Of hat use is the task lifecycle in jbpm3? Looking at the jsf console reveils start,suspend, resume and end. Every task is associated with a form. When it get's submitted the task is completed. So to me, lifecycle of incomplete, complete would make sense, but I don't understand the meaning of 'suspending' a task.

When I tracked the deployment in the debugger, the 100K maxSize came through from the metadata and was passed into the JBC eviction configuration. So 99% sure the bug is in the JMX display of the metadata. Based on your test, that's what I was starting to think as well. So, that leaves me with one other issue to explore. Why is my test so much slower using the StatefulTreeCache, then using the SimpleStatefulCache? I have been having trouble with getting JBoss Profiler working, but Jesper has given me a fix for an issue I was having. Could you recommend specific packages I should make sure I capture with the profiler?

[Design of JBossCache] - Tree versus flat hashmap cache structure

by nonius

We are studying the internals of JBossCache and we are wondering what exactly are the performance reasons that made you choose to struture cache as a tree rather than as a flat hastable. In this tutorial: http://www.jboss.org/file-access/default/members/jbosscache/freezone/docs... We found this paragraph: anonymous wrote : The first version of TreeCache was essentially a single HashMap that replicated. However, the decision was taken to go with a tree structured cache because (a) it is more flexible and efficient and (b) a tree can always be reduced to a map, thereby offering both possibilities. The efficiency argument was driven by concerns over replication overhead, and was that a value itself can be a rather sophisticated object, with aggregation pointing to other objects, or an object containing many fields. A small change in the object would therefore trigger the entire object (possibly the transitive closure over the object graph) to be serialized and propagated to the other nodes in the cluster. With a tree, only the modified nodes in the tree need to be serialized and propagated. This is not necessarily a concern for TreeCache, but is a vital requirement for PojoCache (as we will see in the separate PojoCache documentation). | We agree on the fact that a tree structure can be always reduced to a hashtable, but we do not see particular difficulties in handling with incremental updates to replicate a hashtable. We could not find a previous discussion on this topic in the forum. So, we would appreciate if someone can help us in better understanding the reasons underlying this design choice.

Yeah, probably something like that - perhaps pushing the CL that BMDD sets also to the GenericBeanAspectFactory --> its underlying GenericBeanFactory.

by kabir.khan＠jboss.com

My previous answer is not really related. Is this a standalone example? How can I get the classloader for the aspect? Should I be adding ClassLoaderMD to the BMD on deployment? Once this is this done, I should probably call the wrapped BeanFactory.getClassLoader() from GenericBeanAspectFactory?
