Hi there,
from now on you can download the release candidate 1 for Netbeans 6.8. download it here
For those who don't know anything about the build types for Netbeans releases here are the possible enums :)
- Milestone
- Early Access
- Beta
- Release Candidate
- Release
I was very curious about this release candidate. The most important feature I am missing / waiting for is the Compile on Save feature for Maven Java EE Projects (vote for it here) However, this feature hasn't been implemented yet. In my opinion, this is a must have feature if you develop javaEE projects with maven and netbeans. So hopefully it will be implemented in the 6.8 release version. Let's wait and see.
Another problem I faced with Netbeans 6.8 M2 was the very frequent Glassfish PermGen Out of memory exception. I've been getting it whenever I published too often (means after about 20 deployments of the ear project within an hour).
While working with this release candidate for the last hour this OutOfMemory Glassfish problem hasn't occured. Good news.
Another problem also vanished. Netbeans sometimes crashed when I was trying to insert jsf value binding in xhtml files.
All in all the Netbeans developers are doing a great work. Keep on developing!!! Thanks a lot for this great IDE.

Netbeans 6.8beta, Glassfish V2.1, EJB 3.0 Deployment Problems
Hi alltogether,
Within the last few weeks I sometimes had to face with the following exception, which appeared out of nothing.
Exception occured in J2EEC Phasejava.lang.IllegalArgumentException: Invalid ejb jar [...EJB-1.1-SNAPSHOT.jar]: it contains zero ejb.
Note:
1. A valid ejb jar requires at least one session, entity (1.x/2.x style), or message driven bean.
2. EJB3+ entity beans (@Entity) are POJOs and please package them as library jar.
3. If the jar file contains valid EJBs which are annotated with EJB component level annotations (@Stateless, @Stateful, @MessageDriven), please check server.log to see whether the annotations were processed properly.
At first, I thought it was a problem with changing the snapshot version (see this post)) but this actually wasn't the problem. Maybe, it's a problem of Netbeans 6.8beta version. Anyway, I still haven't figured out the source of the problem, I can only tell you what you have to do to make it work again. Recreate your glassfish domain. Here is a how to link
I hope this is helpful for you. It took me some hours to fix the problem, which was very annoying.

ICEFaces meets JSF2.0
Hello again,
As I have been developing most of my applications with ICEFaces as JSF implementation, I am very curious to test the first version of ICEFaces 2.0 Alpha. The ICEFaces core is now on the Mojarra JSF 2.0.1 runtime.
Read more about it
http://blog.icefaces.org/blojsom/blog/default/2009/10/30/ICEfaces-2-0-Alpha-1-is-out
As soon as I migrated from 1.8.2 to this Alpha version, I will tell you my experiences.

Netbeans, Maven, JavaEE, new snapshot version problem
Hi guys,
instead of celebrating Halloween I struggled with a problem building my maven based javaEE Trainer application in Netbeans 6.7.1. A few minutes ago, I finally found out what was wrong. The problem I am telling you took me about 3 hours to fix...grrrr
So, what was the problem?
I have an Ear project, consisting of a web project, an ejb project and a jar project, all maven projects created with Netbeans.
When I changed the IceFaces Libraries of the web project I also updated all of the projects pom.xml files, as I created a new snapshot version.
From this point on, I wasn't able to deploy/publish the application anymore! The error message I received was: invalid ejb jar it contains zero ejb
The problem was, that I forgot updating the application.xml within the EAR project. In it, I was still using the older snapshot version of the EJB project. So in my projects target folder, the gfdeploy folder had both the older and the latest snapshot version, which made publishing to glassfish impossible. So never forget to update both your poms and your applicationx.xml, if you are creating a new snaphot version!
Enjoy your weekend!
