MyEclipse is unable to open my spring context files.
I get this error message:

Myeclipse version 4.1 M2

[Brian Fernandes]

This looks like an installation issue.

Is this a fresh install of 4.1M2 or did you install it over a previous version? Do you have any other plugins installed?

Can you try adding -clean to your command line arguments just once and see if it clears things up for you?

Best,
Brian.

[Hani Naguib]

Hi, yes this was a bland new installation of Eclipse and MyEclipse.
The other plugins I have are
– CheckStyle
– TestNG
– Perforce
– Easy Explore

How do I add -clean to command line options. Is it enough to type
c:> eclipse -clean

If so it did not fix the problem. When I get some time I will try to install
it again on an eclipse with no other plugins 🙁

Thanks,
Hani

[Brian Fernandes]

Hani,

Yes, that -clean switch specification is fine, as long as it is being sent to eclipse.exe and not a batch file which is invoking eclipse indirectly (and probably not passing the arguments along)

A few further questions. Just confirming: All the bean files that you attempt to open throw the above exceptions?
Can you open normal XML files? What about opening bean files with the XML editor, right click on the bean file and choose Open With > MyEclipse XML Editor?

If you have the time, you could try creating a dummy spring project ina new workspace, in case this issue is due to a corrupted workspace. Use File > Switch Workspace to specify a new workspace location, you can use the same command to switch back to your original workspace later.

Can you open up your plugins folder and see if there are any plugins named *.wst.*? There is a chance that some of your other plugins installed a version of WTP that is conflicting with MyEclipse.

Thank you for your patience,
Best,
Brian.

Yes the problem seems to occur only on Spring files.
I did try opening them as you mentioned with MyEclipseXML Editor, that is what my
second stack trace (above) is.

Seems to work in a new workspace! Any ideas as to what could be corrupting my
original workspace? It consists of 6 projects all of which reside in a directory that
is outside the workspace ( I import existing projects ). Also all the projects are under
version control (Perforce) which marks all files as read-only until I open them for Edit.
Could it be that you need to modify the .project file during the import and that fails causing
problems?

The only place where I see anything called wst is inside MyEclipse/eclipse/plugin. All my plugins are installed under eclipse/plugins and there I can not find any mention of wst.

[Hani Naguib]

Just another note.
I created a new workspace and then imported one of my projects (that contains the spring files).
It also failed to open them with the same error mentioned above. This project is used to store
common files, below is what its .project file looks like

<?xml version=”1.0″ encoding=”UTF-8″?>
<projectDescription>
<name>etc</name>
<comment></comment>
<projects>
</projects>
<buildSpec>
</buildSpec>
<natures>
</natures>
</projectDescription>

The spring file I tried to open looks like this:

<!DOCTYPE beans PUBLIC “-//SPRING//DTD BEAN//EN” “http://www.springframework.org/dtd/spring-beans.dtd”&gt;
<beans>

<bean id=”placeholderConfig” class=”org.springframework.beans.factory.config.PropertyPlaceholderConfigurer”>
<property name=”locations”>
<list>
<value>datasource.properties</value>
</list>
</property>
</bean>

<bean id=”PublisherProperties” class=”com.qualcomm.uione.publisher.domain.PublisherProperties”>
<property name=”publisherRootServerPort” value=”8900″/>
</bean>

</beans>

Hani,

Thank you for all that detail – I was able to replicate the issue, it’s because your base project is not a java project. I should have realized earlier from the stack traces, sorry for the delay.

This is a bug, and we’ll make sure it’s fixed in our next release. In the meanwhile, is it possible for you to convert your “common files” holding project to a java project?

Sorry for the inconvenience caused, and thank you for your patience,
Best,
Brian.

Good news. Thanks for all the help, I will do that.

[mike.ring]

Has this bug been fixed yet? I’m getting basically the same stack trace
Info:
– This was a fresh install of Eclipse/MyEclipse done about 2 weeks ago. Version 4.11 of MyEclipse
– I have no other plugins installed
– I have started eclipse with the -clean switch, and that didn’t fix the problem
– I can create a new project in a fresh workspace, and it works just fine
– My XML editor works fine, but the spring editor doesn’t
– My procedure for creating projects is to create a Java project, add linked folders to point to already-created source and web files, then add web capabilities, then add spring capabilities. So my projects are definetly Java projects.

Any suggestions?

[Brian Fernandes]

Mike,

Yes, this has one has been fixed a long time ago. You’re sure you see exactly the same stack trace?

Also, the XML files you’re trying to open, are they actually present in your project or are they linked or present in linked folders?

Best,
Brian.
