Starting org.eclipse.wst.jsdt.ui plug in

Hello
I would like to know how is this org.eclipse.wst.jsdt.ui plug in being activated during eclipse initialization whenever there is already a project with this org.eclipse.wst.jsdt.core.jsNature nature existing in the workspace. A short explanation or direction to specific documentation topic would be perfect .
Thanks in advance !!

Naushin,
Could you please paste your code here so that we can understand the details.
cheers,
Saurav

"NoSuchMethodError" "org.eclipse.wst.server.core.internal.Trace.trace"?

Hello,
I'm encountering the following when publishing to WebLogic Server via Eclipse with the Enterprise Pack installed. Thanks for any help!

This excerpt is from the Eclipse log.
It's interesting to note that I have no applications deployed to this domain - The result is the same if I attempt to add a simple test application.
I've used this on my Windows XP workstation for some time. This is my first attempt on my Mac!
Mac OS X 10.6.7
Java 1.6.0_24
Eclipse Helios SR2
"Fresh" installations of Eclipse and WebLogic
The latest Eclipse & Oracle Enterprise pack updates
WebLogic starts normally via the shell

Hi,
I was able to reproduce the issue you are seeing. This issue is caused by the fact that there is a new version of org.eclipse.wst.server.core_1.1.207.v20110401_1511.jar which is newer than the version which was shipped with Eclipse JEE SR2 bundle.
The Helios JEE SR2 installers at http://eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/heliossr2 contain the following version org.eclipse.wst.server.core_1.1.206.v20110110_p001.jar.
In your case when you tried with Helios GA and the OEPE update site , I presume you had the "Contact all update site during install to find required software" checked which updated your eclipse installation with the latest 207 version.
There are a couple of options to workaround this issue:
1) download and install all-in-one OEPE kits from http://www.oracle.com/technetwork/developer-tools/eclipse/downloads/oepe-111172-360027.html
2) install eclipse JEE SR2 and install OEPE from the following update site http://download.oracle.com/otn_software/oepe/helios but make sure that the "Contact all update site during install to find required software" option is unchecked.
hope this helps. Please confirm if this resolves the issue.
thanks
Raj

I feel that there is problem in the annotation-manifest.xml
please check it again.

Any idea on how to get rid of this ??

This class will be called while starting the tool

I just tried it on my machine; no issues in Local mode
I recommend opening a ticket/incident with SAP Support to better troubleshoot what the issue might be.
Be sure you installed the support pack with 1.2 and not the new install

Hi ChuckBing, thanks for your reply. I have both versions, j2sdk1.4.2_09 and 1.5.0_04(j2se development kit 5.0 update 4), on F:\ folder when I posted error message here. At first, I only have 1.5.0_04 and J2SE Runtime Environment 5.0 update 4 on F:\. When I started to run eclipse, this error shown up. I thought it maybe the JRE version I have, then I installed j2sdk1.4.2_09 & j2re-1_4_2_09. But the error was still there. Now I uninstall j2sdk1.4.2_09 & j2re-1_4_2_09, this error comes out also. Can you figure out something else? My OS is xp home edition. Thanks. northcloud

My J2ee engine & WebDynpro admin & sdm work.
What is the best solution to fix this problem without having to reload netweaver?

Hello Peter,
you should try to find more information about the error. In Error Message: Unable to restore Web Dynpro Explorer I already described how to find more information about DevStudio errors.
As you already are aware of the .log file, only the described third way (-consolelog) might help.
Good luck + Kind Regards, Frank

Org.eclipse.jdt.launching.localJavaApplication Error

I was developing nicely on Web Sphere Studio Developer Version=5.1.0
(with eclipse Release 2.1.1) but I just started getting the error "No
Tab group defined for launch application type/n
org.eclipse.jdt.launching.localJavaApplication" when trying to run or
debug. I was trying to parse&validate an XML file and getting a log of
the Parsing errors.This might have done something. However, it was
working before..Any ideas before deleting and reloading Eclipse?
