rdbarri ,

Sorry that you are seeing this issue with MyEclipse.

Can you answer some more questions for us to investigate further ?

1) Paste your Build Id here from Help > About MyEclipse Enterprise Workbench > Build Id.

2) Can you also share your OS and version details ?

3) Clear the contents of the .log file which is located at <workspace dir>/.metadata/.log. Now replicate the issue and paste the entire contents of the .log file here.

Hi,

I have exactly the same problem with MyEclsipe 9.1.0 and JSP files. Same behaviour in editor, same error log and stack trace.

Code:

!ENTRY com.genuitec.eclipse.webdesigner3 4 0 2011-09-01 08:43:39.578 !MESSAGE !STACK 0 java.lang.NullPointerException    at com.genuitec.eclipse.webdesigner3.editors.WebDesignerMultiPageEditor.previewInMozillaBrowser(WebDesignerMultiPageEditor.java:1189)    at com.genuitec.eclipse.webdesigner3.editors.WebDesignerMultiPageEditor.previewPageChange(WebDesignerMultiPageEditor.java:1096)    at com.genuitec.eclipse.webdesigner3.editors.WebDesignerMultiPageEditor.pageChange(WebDesignerMultiPageEditor.java:1024)    at org.eclipse.ui.part.MultiPageEditorPart$2.widgetSelected(MultiPageEditorPart.java:290)    at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:234)    at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84)

... sorry - I forgott:

- same build ID (Version: 9.1 Build id: 9.1-20110701)
- same OS (Win 7 Prof 64 bit SP 1)
...

Hi esiegemun

Did you find any solution???

Not at all and no idea!

There is an other error in the log

Code:

!ENTRY org.eclipse.osgi 2 0 2011-09-01 08:43:06.474 !MESSAGE While loading class "org.eclipse.wst.jsdt.internal.core.JavaModelManager$16", thread "Thread[Worker-6,5,main]" timed out waiting (5000ms) for thread "Thread[Worker-2,5,main]" to finish starting bundle "org.eclipse.wst.jsdt.core_1.1.2.me201106211924 [1210]".

I'm not sure, if there exist any relationship between both errors ...

As I can see, the trouble with the JSP editor (NPE in the log) exists already for some weeks. I've not used the JSP editor for some time - fail to see the error.

esiegemun , rdbarri ,

Apologies for delayed response.

1) Firstly Visual Designers are not available for 64 bit installations on Windows.
Is your MyEclipse installation a 32 bit version or 64 bit version ?

2) Can you start the IDE with -clean and check if the issue persists ? Here is an FAQ for clean : http://myeclipseide.com/PNphpBB2-viewtopic-t-10280.html

3) If you still see the issue, clear the contents of the .log file which is located at <workspace dir>/.metadata/.log, replicate the issue and then copy paste the entire log contents here for further investigation.

Hi..

My installation of MyEclipse is 64 bit version.

How to move to 32 bit...MyEclipse
and will 32 bit MyEclipse cause any issues..because my OS is 64 bit...

rdbarri ,

If you run the installer for MyEclipse, it will give you option of installing the 32 bit or 64 bit version as you have 64 bit OS. Choose the 32 bit version and install it.

You can either uninstall your existing MyEclipse and rerun the installer or you can simply install it to a different location. There should not be any issues in running MyEclipse 32 bit on 64 bit OS.

Let me know how this works for you.
