What operating system and version are you running?
What Eclipse version and build id are you using? 3.02
– Was Eclipse freshly installed for MyEclipse? YES
– Are any other external plugins installed? NO
– How many plugins in the <eclipse>/plugins directory are like org.eclipse.pde.* (8)
What MyEclipse version are you using? 3.84
What JDK version are you using to run Eclipse? MacOS X 1.4.2
What JDK version are you using to launch your application server? MacOS X 1.4.2

I have a project where for some reason after making changes the struts-config.xml will not show. I get an error “Unable to create part” followed by an error message “An error has occurred when activating this view”. The struts-config file will not show. I can, however, open the file with the XML viewer.

Checking the log file I see this entry:

Patrick,
There are a lot of errors in here, so let’s try and figure out exactly what is going on, do this please:

1) File > Switch Workspace > C:\tempworkspace > Hit OK, let it restart.
2) File > New > Project > Web Project
3) Add Struts Caps to the Web Project
4) Open the struts-config.xml file, did it work?
5) If YES, close the file, and go find your other struts-config.xml file and copy ontop of the one you just opened in the new project. Now open it.
6) Did THAT work?
7) Open the C:\tempworkspace\.metadata\.log file, is there anything in there? Paste it here please.

Originally I was going to say that the bug looked like you might have GEF installed in your <eclipse>\plugins directory and might be conflicting with the version MyEclipse ships, so you might want to check that.

Also you can try using -clean as outlined here: http://www.myeclipseide.com/FAQ+index-myfaq-yes-id_cat-30.html#343

Also here is the struts-config.xml file. I’m still trying to learn so maybe you’ll see some sort of error:

<?xml version=”1.0″ encoding=”UTF-8″?>
<!DOCTYPE struts-config PUBLIC “-//Apache Software Foundation//DTD Struts Configuration 1.2//EN” “http://struts.apache.org/dtds/struts-config_1_2.dtd”>
<struts-config>
<data-sources />
<form-beans >

</form-beans>

<global-exceptions />
<global-forwards >
<forward name=”unknown” path=”/unknown.jsp” />

</global-forwards>

<action-mappings >
<action
attribute=”courseSearchForm”
input=”/courseSearch.jsp”
name=”courseSearchForm”
path=”/courseSearch”
scope=”request”
type=”eclipse.kickstart.struts.action.CourseSearchAction”>
<forward name=”success” path=”/results.jsp” />
</action>

</action-mappings>

<message-resources parameter=”eclipse.kickstart.struts.ApplicationResources” />
</struts-config>

TIA I really appreciate the help

I’m asking our mac dev to test this, it opens fine on Windows, I think this might be a mac/gef/issue.

Patrick,
We got the file and tested it on our Mac setup, everything worked fine. We are wondering if something is wrong with your project, can you do a File > Export > To ZIP and email us the project?

support@genuitec.com ATTN Riyad

and a link to this thread so we know why we are recieving the file. Thanks!

Ok he imported the project and everything worked fine, can you try a fresh install of Eclipse and MyEclispe AND a clean workspace? I can’t help but thing some silly minor problem is going on here…

Sorry for the delay in answering this. I didn’t get the notice.

Excellent that worked! Previously I’ve done fresh installs, but have always copied my workspace back into the eclipse directory. The problem still remained. Doing the import seems to have fixed the issue.
Thank again.
