Netbeans 5.5 Enterprise Pack Failure on OS X

I completely removed Netbeans including all directories in my home folder. I also removed glassfish and started with a complete new installation.

Once I performed the installation, everything worked as it was supposed to do. The only difference between this install and the previous installations was that I downloaded updates to the IDE after installing and before I installed the Enterprise Pack.

I could not reproduce which I could do consistently two days ago. I have installed the updates and it continues to work. I closed the issue on Issuezilla.

This was very strange.

Persistence Unit or Persistence Context?

Which to use for a particular application depends entirely on the environment, or preference.

• @PersistenceUnit annotation is used in J5SE applications to handle Java Persistence API (JPA) persistence management. You may use a PeristenceUnit in an application inside a container, but it must be managed by the developer instead of the container.

• @PersistenceContext annotation is used for Container Managed Persistence (CMP). This relieves the developer of having to worry about connection management.

Netbeans 5.5 Released

Netbeans 5.5 was released today. The new visual web pack preview is included. The visual web pack provides the same level of functionality from Creator 2 to Netbeans. I am so excited to get it running on my Mac.

The visual components of JSF are realized for the first time in Netbeans. So far the only thing I do not like is that Creator 2 projects are not interchangeable with Netbeans. If you Open a Creator 2 project in Netbeans it will not work again in Creator 2.

I installed the Enterprise Pack with an existing installation of Glassfish 9.1 (V2 Build 19 Milestone 2), and the server would not start. I tried a number of things but it appears some corruption occurs. If you use the default included application server everything works as expected.

The failed server was running on:
PowerMac G5 Dual 2GHz 6.5GB RAM
OS X 10.4.8 (PPC)
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-112)
Java HotSpot(TM) Client VM (build 1.5.0_06-64, mixed mode, sharing)
Glassfish 9.1 (Version 2 Build 19 Milestone 2)

I opened an issue on the entpack at Netbeans. Issue # 88197

Providence

I was just trying to decide if I wanted to open a Blogger account, and I selected a random person going by... Little did I know I would pick someone from my home state who does not live very far from me. Rachel Parker is her name and here is her blog.

Strange coincidence...or fate. One can never tell, but it was definitely the deciding factor. I shall leave it as providence.

Miscellaneous Notes

I tried to see about creating a blog on java.net, but have not found a link to where to sign up. I may need to ask a moderator.

I am working on completing a list of Java SE/EE performance tips. Once I have compiled the list I will post it to the blog.

Greenville Java Users Group Graduates Incubator

Finally I have had a chance to complete the steps required to graduate the GreenJUG site from the java.net incubator. I still need lots of assistance from the Java user community to make our JUG a success, but this will come with time and perseverance.

I have asked for some items to give away at meetings from Sun, O'Reilly, and JetBrains. Sun and O'Reilly have really stepped up to offer a bunch of goodies. We will see if JetBrains will offer some goodies.
