One extremely valuable skill you should learn as someone who works with Java is to understand a thread dump. One of my customers this week had a situation where their web application was acting up and we were able to see some misbehaving code very quickly by looking inside their application to see what each thread was doing. It might be intimidating to you at first, but I can’t emphasize enough how much reading thread dumps will help your troubleshooting skills. This post...

In the OTN WLS General forum someone asked a question regarding using Shared Libraries to share static web resources among applications. “Basically, we are trying to load jquery, css files, shared images, and what not into a shared library for access from other Web Applications.” Shared libraries will handle this use case well. I’ve put together a basic example using a simple image that is put into a shared library that is referenced by another web application. The image...

Since I’ve joined Oracle via the BEA acquisition I have had the opportunity to start learning JDevleoper and I like it a lot, but I’ve had some bumps in the road since I’m so used to Eclipse. Much of the IDE tooling for the Oracle’s SOA, BPM, and Application Server products is migrating to JDeveloper, which is Oracle’s comprehensive IDE. This gives developers using Oracle products a very easy-to-use and highly integrated development environment. Oracle is still strongly...

Overview *10/21/2008 Update* I mention in this post that I had an issue with Dojo 1.2.0, well I figured it out, read Part 3 for details. Last week I wrote about the introduction of a HTTP Publish-Subscribe Server in WebLogic Server 10gR3. The new feature is based on the concept of Comet and implements the Bayeux protocol and is very useful for publishing events immediately to subscribed clients over HTTP. There are many uses for a feature like this, essentially any time...

Now that Workshop 10.3 is available, I test drove the new JEE 5 support with a very basic EJB 3 scenario. Namely, create a remote stateless session bean and invoke it from a stand-alone java client. I stumbled around at first since my first guesses for using the new Workshop JEE5 feature support worked were incorrect. So I've decided to write up my experience in case it will help someone else. It turns out that JEE 5 really does simplify things, and overall I think it is...
