When I try to open any struts-config.xml file with MyEclipse Struts Editor it results in following exception:

I’m using fresh installation of MyEclipse 4.0.3 and Eclipse 3.1.1

Thank you for any help, you can provide.

Petr,

Did this happen in any earlier version of MyEclipse or has it suddenly started happening for all your config files?
I assume you have added Struts capabilites to your project, but please confirm this for me.

For testing, could you create a fresh dummy struts project and try opening the struts-config.xml file that is created for that project?

Best,
Brian.

I have been using different versions of MyEclipse for last half year and everything was ok until now.

I assume you have added Struts capabilites to your project, but please confirm this for me.
Yes – it is old project. I tried 3 different files form 3 different projects and in every case it produced an error.

For testing, could you create a fresh dummy struts project and try opening the struts-config.xml file that is created for that project?
I created new project, added Struts capabilities and struts-config.xml file was created. I was able to open this file in Struts Editor. When I tried to add something in Designer it seemed to be working but even source code was updated, Designer window stayed clear.

Petr,

I’m going to have to ask you to answer all the questions here: Posting Guidelines – which you haven’t answered already.

If you upgraded an existing insallation, please restart it with -clean. Which version of MyEclipse were you using prior to this?

Can you copy a config file that is not working to your dummy project and see if the editor works? If not, can you mail a copy (if possible) of your struts config file to support@genuitec.com ATTN Brian?

For testing, could you create a fresh dummy struts project and try opening the struts-config.xml file that is created for that project?
I created new project, added Struts capabilities and struts-config.xml file was created. I was able to open this file in Struts Editor. When I tried to add something in Designer it seemed to be working but even source code was updated, Designer window stayed clear.

What struts element did you create (some do not have graphical representation)? Any errors in the log for this use case?

Best,
Brian.

I solved it. The problem was in JRE. After installation of new JRE everything works fine.

Thank you for your help.

[Brian Fernandes]

Petr,

Glad it’s working now.

Best,
Brian.
