[JBoss ESB Development] - Re: Performance Improvement Proposal: Cache result of HttpSe

by dward

That's good to know Bill, thanks. The difference with what I'm doing is that it's not a member variable (the map) that is being set lazily, but a populated entry in the map, so we just have to be careful against ConcurrentModificationExceptions. Kev, if you're okay with me not using ConcurrentHashMap (and instead using synchronized as I elaborated on above), let me know. Either way, I'll wait for your word before I commit to the performance workspace and 4.7 CP branch. Thanks.

[JBoss ESB Development] - Re: Performance Improvement Prop: Cache PortReference.extend

by dward

BTW, after changing ActionProcessingPipeline (and the log4j file - haha), this bottleneck fell off JProfiler's radar. If you want I can tweak the log4j file in the zip. I'll wait for what you wanna do before I commit to the performance workspace + 4.7 CP branch.

[JBoss ESB Development] - Re: Performance Improvement Prop: Cache PortReference.extend

by dward

There were indeed a couple debug statements in ActionProcessingPipeline that ended up causing extendedToString being called because they weren't surrounded in a isDebugEnabled(). I've fixed those. What threw me is that after fixing those, I still saw extendedToString being called (7 times for just 1 web service request!). After looking at the call stack, the debug statements were still being invoked. I looked at the jboss-log4j.xml file, and I had to uncomment out the section that limits org.jboss to INFO. Any reason why the log4j level isn't INFO by default? I think we might need to change jboss-log4j.xml in jbossesb-server-base.zip.

[JBoss ESB Development] - Re: Performance Improvement Proposal: Cache result of HttpSe

by dward

I don't see how using ConcurrentHashMap would be any different than Collections.synchronizedMap(new HashMap()). So it would still open the door for multiple calls to request.getLocalName(). I also don't want to use oswego classes if not necessary.

[JBoss Microcontainer Development POJO Server] - Re: Cleanup path for Structure Deployers

by johnbailey

I would like to open this conversation up again. I will be working on the VFS3 integration full time in the near term. I would like to make sure we are still going to move forward on the registry approach discussed above? Has anyone had any more insight in the past month?

[JBoss Web Services Development] - Re: JBossWS Deployers Architecture

by bill.burke＠jboss.com

Thanks for explanation. I've looked at your code a bit. Are the aspectized deployers just a abstraction for JBossWS so that it can move/integration smoothly between different deployment mechanisms? All and all, it looks like things would be pretty straighforward to create a RESTEasy integration. Its just a matter of writing descriptor and real deployers and then importing, modifying, and exporting the correct metadata. BTW, would be interesting to hear what you think of the JBoss 5 deployment framework. So far, it looks like it is solving what it was intended to do.

[JBoss AS Development] - jboss-annotations-spi Release

by ALRubinger

The naming server (MC integration) has a snapshot dependency upon: http://snapshots.jboss.org/maven2/org/jboss/integration/jboss-annotations... ...though there's no formal release in the M2 repo. Who maintains this project, and can we get an alpha/beta? Last commit was Ales, and if there's a document with release instructions I'll be happy to do this.

[jBPM Development] - Extracting information from a jpdl file

by ajaygautam

I have a state diagram in a jpdl file. I need to extract possible transition strings from the current state, so that the UI can figure out which string to send back to the jbpm process. Can't seem to find an easy way to do this. What am I missing? Its seems to be a basic thing to do. Any help / pointers will be greatly appreciated. Thanks Ajay (Using jbpm 4.2) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269436#4269436 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4269436
