error with GPD 3.0.8 Eclipse plugin

[mennen]

Hi,

I migrated from GPD 3.0.5 to GPD 3.0.8 and i got problems in Eclipse (3.1.2).

Here is the list of errors i get, which disables my workspace, so i can't work at all:

An internal error occurred during: "Initializing Java tooling".

Did anyone encounter the same problem with this plugin?

When i switched back to the 3.0.5 version it works fine once again..

THanks in advance,

[mdonato]

I'm facing the same problem ....

[forjbpm]

Hi!
How did you upadate it?? using site modeule or feature??

It looks like that its not able to find ui.jar...

[mdonato]

I downloaded the file "jbpm-gpd-site-3.0.8.zip" and install from eclipse uptade !!!

[boerse]

and can you deploy? since i updated my version i cannot do it any more....

[mdonato]

I do not download the engine jbpm-3.1 ... couse at this moment i only need the gpd ...

i use gpd only for develop flows !

so at another moment i publish it in our application in an j2ee container with jboss integrated ..

Then, i can't answer this to you !

[boerse]

hi mdonato, and how do you deploy your .pars in the JBoss? have you ever tried using eclipse?

[koen.aers]

The best solution for this problem is to first manually add all the libs from your jBPM classpath container to your project (3.0.5) and then get rid of the classpath container. If you then startup with 3.0.8 all will be fine.

i also faced same problem
elipse 3.1, 3.1.2 same..
gdp 3.0.5, 3.0.8 same

and i tried to reinstall eclipse
it's ok.

maybe, other library affect to gdp
my system have myelipse, editor list, mavenide etc.

good luck

Can you please be more specific about what I should do? I'm not really an expert so i don't know what you mean by "jBPM classpath container" and what project you mean by "project (3.0.5)"? I do have a jbpm.3 project, is that what you meant?
I tried to uninstall the 3.0.5 and 3.0.8 and then reinstall 3.0.8 once again, but still didn't work..

Thank you,

Mennen

i faced the same problem,
to solve it, i installed a fresh eclipse (3.1 or 3.2) and jbpm 3.1 then it worked fine.

[koen.aers]

Mennen,

Installing a fresh Eclipse is definitely the best thing you can do if you are no expert.
Otherwise, have a look at each of your 'process' projects in your workspace. There should be a classpath container called 'jBPM 3.xxxx' containing a number of jar file references. You have to locate each of these jar files and add them to the library path of your project. If this is done, simply delete the classpath container.

Koen

I reinstalled eclipse 3.1.2 and i'm still facing the same problem!!

Please tell me what i'm missing

[koen.aers]

You are probably reusing the workspace you had in your previous installation. Getting rid of the classpath container is the only option then.

Koen

[mennen]

i am in fact using the same workspace as before.. can you please be kind enough to tell me what you mean by classpath container?

Thank you for your help,
