Error creating Seam 2.1.0 SP1 Web Project with Tools 3 beta1

[elenctic87]

I am trying to create a new Seam Web Project with JBoss Tools 3.0 Beta1. After going through the entire wizard and setting up the facets and db connections, I get a pop-up error stating: "Failed while installing Seam 2.0" Reason: "Failed while installing Seam 2.0". Clicking the details button reveals "java.lang.NullPointerException", but nothing more. Since I start eclipse from the command line in linux, I can see more details about the NullPointerException. Here are the details:

As some background, I am running a fresh install of Ganymede. I am using Tools 3.0 Beta1 as a dropin (dropin/jbt is a symlink pointing to the location where I unzip'ed the Tools download). Lastly, I did an update within eclipse to ensure I have the latest versions. Am I missing something in the install process? Any ideas how to overcome the exception so I can use all the awesome new features of Tools 3.0 Beta1?!

[maxandersen]

hmm....this looks very much like a old bug in Eclipse Dali (JPA) support which should be fixed in Ganymede.

Are you 100% sure you are running Ganymede and not an old install ? :)

The workaround for the old bug was to not choose JPA when creating the project but enable it after the project have been created in the Project Facets properties on the project.

Let me know if that works and wether it keeps happening on new projects since then we need to follow up with eclipse Dali project.

[elenctic87]

I am 100% sure I'm using Ganymede (info from Help->About Eclipse: Eclipse Platform, Version: 3.4.1, Build id: M20080911-1700).

I tried creating a new Seam Web Project using the Configuration settings of "Dynamic Web Project with Seam 2.0". This does not include JPA. I still get a NullPointerException. There is no verbose exception information on the linux shell console from which I started eclipse, however. I just tried again to create a Seam 2.0 project with JPA support and all I got was the NullPointerException (no verbose exception output this time.)

What other info can I give you to help solve this? I am doing something really basic and running into this error. With WebTools 3.0 alpha 1 and this exact version of eclipse I did not run into this error. (Mind you, I'm not mixing alpha1 install with beta1 install, I started from a fresh eclipse).

[maxandersen]

go to Error log and see the full error log ...please show the full trace.

Is it the same NPE ? you should not get any...

[elenctic87]

Here are the two errors that are generated when I try to build a Seam 2.0 project with JPA.

[maxandersen]

do you touch any facet's settings besides the default ones ? I can't reproduce this ;(

[elenctic87]

This appears to be the worst kind of problem. For me it repeats every time I try it, and for you, never. I am using the default settings for Dynamic Web Project with Seam 2.0 and am changing nothing else on any facet. Are you using the same build of eclipse that I am using (M20080911-1700)? What else can I do?

[maxandersen]

what happens if you do it with a clean workspace ?

[elenctic87]

With a clean workspace and a newly-created server I get the same error (exceptions).

[maxandersen]

Please show the exact exceptions. They cannot be the same since by default there is no JPA enabled.

[elenctic87]

I get this exception with DWP Seam 2.0, No JPA. It occurs within a brand new workspace in Ganymede. Please see my next post for exceptions that occur with JPA enabled.

Well, my problem has a frustratingly simple solution: use Eclipse Ganymede SR1, not the original Ganymede release. A note on the JBT 3.0 Beta1 news release page might save some other people the headache of trying to get 3 Beta1 to work with the original Ganymede release. Thanks, Max, for at least looking into this with me.

Thanks for letting us know.

This issue is not closed yet. It's not simply a matter of installing the Ganymede SR1. I installed Oxygen XML's XML plugin (com.oxygenxml.editor_9.3.0) in the dropins/ directory and I see the same errors as earlier in the post all over again. I am definitely using the version of the plugin for Eclipse 3.4. The only work-around is to remove the Oxygen eclipse plugin from dropins/. I really would like to use the Oxygen XML plugin in conjunction with Tools 3 but right now I can't. This same plugin works with previous versions of JBoss Tools (i.e. v2).
