OpenESB v2.1 M2; Wikis Reminder

Posted by editor on April 16, 2009 at 5:18 AM PDT

The Open Enterprise Service Bus (OpenESB) project released Version 2.1 Milestone 2 on Tuesday:

This milestone includes numerous bug fixes compared with the previous milestone. This milestone introduces an additional installer that will only install the runtime and design time components on top of an existing installation of GlassFish and NetBeans. The full installer now also supports AIX.

You can download OpenESB v2.1 M2 on the OpenESB downloads page.

The OpenESB developers believe that, with Milestone 2, OpenESB v2.1 is beginning to achieve some stability. Their current schedule has Release Candidate 1 being available in just a few weeks.

Given its critical role in the development of the National Health Information Network, it's clear that OpenESB will be gaining significant recognition in the coming months and years. The project has come a very long way since Sun's JavaOne 2005 introduction of:

the Java ESB, the first fully open sourced enterprise service bus implementation based on the Java Business Integration (JBI) specification (JSR 208) and reference implementation.

Changing topics, I want to re-remind everyone about the upcoming changes to Project wikis. Sonya Barry's recent blog posts The Big Upgrade Part Two: What's happening to the wikis? and More Wiki Upgrade cover the upcoming changes, and include lots of comments and conversation with the community.

Tomorrow, April 17, is an important day: the current wikis will be locked for editing (they'll become read-only). On June 12, the current wikis will go offline. During that period, all data from the current wiki will remain available for integration into the new wiki via page redirects. As Sonya notes:

A text dump snapshot of the entire wiki on Friday afternoon (taken after we turn edit permissions off) will be available via the docs and files section of the java-net project, so there will be no permanent loss of data. If you want to do the wiki conversions yourself after the upgrade, you will be able to access your data there, and then submit your own list of page redirects which will be updated on the server weekly through June 12.

Sonya and her team are quite aware of the difficulty a migration of this type entails for the user community:

I wish I had the power to wave a magic wand and make it all just happen. I don't, but I hope you will all take full advantage of the help we can offer...

In Sun's Garbage First Collector Largely Eliminates Low Latency/High Throughput Tradeoff, Charles Humble looked into the advantages of Sun's new G1 JVM technology: "Sun's Garbage First garbage collector (hereafter referred to by its nickname G1) is the new low latency garbage collector planned to replace CMS in the Hotspot JVM. It is a server-style collector, targeted at multi-processor machines with large amounts of memory. There are two major differences between CMS and G1. The first is that G1 is a compacting collector..."

Bruce Eckel summarizes What I learned at Java Posse Roundup '09 based on his own notes and some from other attendees: "1. Most people have been trained to believe they can spend freely without risks or consequences. So in most software development organizations, discussions of technical debt and risk management are seen as annoying and "negative thinking." We need to change this..."

In the Forums, jaymalya seeks clarification relating to authentication in glassfish & apache: "Hi. We have deployed one app in glassfish (v2.1) which uses standard JAAS authn & Authz mechanisms. The app is making getRemoteUser and isUserinRole to derive the ACLs. The app is using one LDAP realm. When we login to the app directly, everything works great. However, when we try to connect to the app via apache ( we authenticate through siteminder on apache), we are getting double prompted - one from apache/siteminder & again from the glassfish realm I can see REMOTE_USER header is getting populated . Is there any way to tell glassfish to accept the REMOTE_USER as the principal & then do LDAP checkups to verify authorization policies ( and may be the password)?"

peterdelaney has a JEE LifecycleListener Question: "Hello; I have a messaging application that, hopefully, will run in the SUN application server (glassfish). We will have clients call our application and our application needs to post a message request to a third party application via RV messaging. The third party has provided a Java api for us to call, but under the covers a RV message is sent out then a response is returned. This returned response is then parsed and sent back to the calling client. We plan on using LifecyceListener object to execute the call between the EJB and the third party application. We plan on spinning some threads during that call. This from what I am told is the proper implementation especially when running a thread. My first question is this the proper way to go?..."

And lamah is conversing Re: Swing performance problems: "Although classloading is a major bottleneck in big applications during startup I don't believe reflection is the way to go to solve it. Like you say, you lose easy refactoring/discoverability and compile time safety. Currently, according to JProfiler, loading a class only takes 400ns (in my app) which I find is pretty quick so I don't expect to find any more ways to improve it (except to load fewer classes perhaps). The result may be somewhat incorrect since JProfiler just averages the time. Still, loading 2000 classes will cost somewhere along 600-1000ms of startup time which is not that bad if you consider what actually is done during class loading. If you also do multiple startup related tasks in parallell you can lower the impact of classloading on total startup time even more on multicore machines. My point is that applications made with Swing takes too long to start up..."
