juliencr,

1) Can you please share your installation details from menu MyEclipse > Installation Summary > Installation details ? Please paste them here for me.

2) How are you trying to open the Struts-config.xml? Is it using the MyEclipse Struts Config editor or MyEclipse XML editor?

3) Start MyEclipse with – clean as argument. Here is how it can be done :
https://www.genuitec.com/forums/topic/troubleshoot-using-the-clean-command-line-argument/

4) Switch to a new workspace, create a new Web project and add struts capabilities to it.

Here is a thread which shows how to build a struts project :
http://www.myeclipseide.com/documentation/quickstarts/struts/

Now try opening the struts-config file and check if the issue persists.

Let us know how it works for you.

I am trying to open a struts.xml with MyEclipse Struts Config Editor, xml works fine

[support-swapna]

juliencr,

1) How did you perform the update? ? Is it using Pulse/All-In One installer/Archived Update site?
2) What was your previous version of ME?
3) Are you trying to open an existing struts.xml ? Did you check for a new project?

I would recommend you a quick fix using pulse. Please do the following –
1. Open Pulse. (Start > Programs > Pulse > Pulse Explorer or download the same from http://www.poweredbypulse.com)
2. Start Pulse
3. Select appropriate Eclipse realm from the dropdown list. If you are on ME 8.6, select Eclipse Galileo; in case you are on 9.0, select Eclipse – Helios
4. From My Profiles, Select your MyEclipse profile
5. Right click on the same and click on re-install and run
6. This will open a wizard which will guide you through the rest of the steps.
7. Switch to a new workspace and check if the issue persists. If yes then copy paste the contents of the .log file which is located at <workspace dir>/.metadata/.log.

Let me know how this works for you.

I did the update via pulse, All in one installer
it was the version before 9
using an existing struts.xml

I removed eclipse deleted the .metada folder and reinstalled a new version, could wait another day because it was crapping out, needed to work but, it is working now

juliencr,

Glad that it is working fine.
Do let us know if you have any other issues.

I’ve been struggling with this error as well, and I’ve tossed the workspace and rebuilt it a few times.

jwindberg ,

Sorry that you are seeing this issue with MyEclipse.

Can you answer some more questions for us ?

1) Can you share your OS and version details ?

2) Are you working with an existing struts.xml ? Create a new struts project and check if you see the issue.

3) Did you try starting the IDE with -clean as suggested in the earlier responses ? Also clarify if you have tried a reinstall of MyEclipse from Pulse. If no then please try and check if the issue persists.

4) Did you try the solution posted by user juliencr of removing the .metadata folder and reinstalling MyEclipse ? If no then please give it a try.

Let us know how it works for you.
