Hi all,

I have the same problem.

I get the following error msg while opening a Web Dynpro view or component controller:

Plugin name: Web Dynpro TS Model
Plugin ID: com.sap.ide.webdynpro.tsmodel.application
Class: com.sap.ide.webdynpro.tsmodel.application.actions.EditViewAction
...
Exception: org.eclipse.swt.SWTError: No more handles

This means, I cannot work anyway. It always results in the above error.

I am running Windows 7 x64

I installed 32 bit software of:

- NWDS 7.02 SP09 (also tried older versions of 7.02 and 7.01)

- Java SDK 1.4.2_19 (we need Java 1.4 for our project)

What I tried to fix this issue:

- installed several versions of NWDS

- delete .dtr / .dtc and .metadata folder

- I didn't count how many reboots I made, but it was a lot

- I started SapIDE with and without vm-args

My vm args are:

"C:\Program Files (x86)\SAP\IDE\IDE70\eclipse\SapIde.exe" -vmArgFile vm.parameters -vm "C:\Program Files (x86)\Java\j2sdk1.4.2_19\bin\javaw.exe" -clean

The file vm.parameters contains the follwing content:

-Xmx768m

-Xms256m

-XX:PermSize=64m

-XX:MaxPermSize=256m

(As I said, I tried it with args and without)

- I also deleted and restored the plugins in .metadata\.plugins as described in this thread

Nothing worked. I always get the same error msg "Web Dynpro TS model -> SWTError: No more handles".

Can anyone help to solve this issue?

Thanks!

try to close all windows, exit and run again.

if it not helps restart your computer, if it helps - probable reason was insoffitient memory.

may be reason is a bad document in eclipse cache,

try command

eclipse -clean

The clean option will clean out any caches that Eclipse has created.

Hey Vladimir,

Thanks for your promt reply...

I have restarted my pc but didn't workout.

i tried the scond option as well. "eclipse -clean" afte running this i get below message.

The procedure entry point JVM_FindClassFromBootLoader could not be located in the dynamic link library jvm.dll.

Then Click OK now gt this.

Eclipse

-

---

JVM terminated. Exit code=1

C:\WINDOWS\system32\javaw.exe

-cp C:\Program Files\SAP\IDE\IDE70\eclipse\startup.jar org.eclipse.core.launcher.Main

-os win32

-ws win32

-arch x86

-showsplash C:\Program Files\SAP\IDE\IDE70\eclipse\eclipse.exe -showsplash 600

Any other soluation..

[junwu]

it's quite clear that it is using the wrong jvm.

please set the java home

you can also specify the jvm when start the nwds.

Hi Johan,

Thanks for yo Ans, i solved it doing some un logical things which my slef sure about.,

1. copy the workspace\.metadata\.plugins\*org.eclipse.core.resources* on temp location and then delted it from workspace.

2 Started NWDS.

3. Closed the NWDS and restored the org.eclipse.core.resources on same place now its started working now

Thanks
