Tip to improving glassfish performance

Today I was reading an entry (Customizing Glassfish v2 with 23 unpublished properties) from the Gestalt Shared Feed about hidden properties in glassfish v2. One very interesting tip to improve performance for glassfish would be to set the enableSnoop to false. Basically setting this property to false stops grizzly from logging the requests/responses to the log file. See the rest of the article on how to actually set the property in glassfish.

Using the OpenESB J2SE version and netbeans

As I mentioned in JBI deployment options, OpenESB can run as a standard J2SE application. This is a nice option that has some advantages such as getting started quicker without the need of downloading the rather large (300+MB) OpenESB bundle that includes glassfish/openesb and netbeans. The JBISE version is only 4.3MB. For those of you not needing a J2EE container this might be a valid option.

The only other missing piece is the tooling support to create Composite Applications. This is included in Netbeans v6 which is a part of the large OpenESB bundle. But since you are not downloading that you need to ability to get netbeans v6. Here is the netbeans v6 nightly builds location: http://bits.netbeans.org/download/6.0/nightly/.

Good luck and happy downloading.

Glassfish v3 and JavaEE 6

More than likely most haven't gotten the chance to use JavaEE 5.0 yet, but I think it's important to look ahead at what is coming down the road. I believe, container-wise, JavaEE 6 is going down an excellent path of easier development by making their container as small as possible (15k) and startup time super fast (less than 2 seconds). How did they achieve that? Modularity.

For some reason I just realized that the Reference Implementation (RI) for JavaEE 6.0 is Glassfish v3. Skim this presentation about the goals of JavaEE 6.0 (roughly about 15 quick slides). Also, here is a walk-through on how to use Glassfish v3 (install jruby container, web container, etc).

Just for the record, also keep in mind that JavaEE 5.0 is implemented by Glassfish v2.
