Hi,

I’m trying out MyEclipse 5.0M1 with Eclispe 3.2. Having some problems with the JSP Designer. Whenever I try and create or edit a JSP, I get the following pop-up message:

[b]Unsupported content type in editor. 
To associate file extension with a supported content type, please see Content Types Preferences Page.[/b]

I went into the Content Types Preferences Page, and checked the JSP settings, which seems to be ok.

Any ideas if this is a bug, or am I having some configuration issues here?

Thanks!

Looks like a config issue, does this happen when you try and open a certain type of file and you cannot see it’s content, or can you open the file and edit it and this only happens when you try and switch to design mode or something?

[everbright]

It happens whenever I tried to create or edit a JSP. The default editor for JSP that Eclipse uses to handle JSP is the JSP Designer.

The Designer will launch, but it will be blank. The pop-up happens whenever you click on the tab for the Designer.

Did a check on the error log. Got the following errors/warnings whenever the pop-up happens:

Hope that provides some clues to this issue!

It looks like you might have a different version of WTP installed besides what MyEclipse ships (notice the class not found exception, API break). Check your Eclipse dir, go into the Plugins dir and look for any “wtp” or “sse” plugins, see any?

[everbright]

I’m using a clean install of Eclipse 3.2. Couldn’t find any wtp or sse, or maybe I’m not recognizing them. Any ideas what they are called?

[Riyad Kalla]

com.ibm.wtp I think or org.eclipse.webtools

[everbright]

Hi,

I’ve checked both the Eclipse and MyEclipse plugin folder. Can’t find the packages you mentioned 🙁

[Riyad Kalla]

Strange, the only thing I can ask you to do is wait for our M2 release here in about a month or so. We are completely replacing the designer, so troubleshooting the old designer framework now would serve no purpose.

Sorry for the inconvenience. If you had the time you might try a Eclipse 3.2RC5 and MyEclipse 5.0M1 install to new dirs and see if that worked (that’s what I have running here).

[everbright]

ok. That makes sense. Will wait for MyEclipse 5.0M2 then! Thanks for the attention on this issue!

[everbright]

just to let you guys know. I’ve tried using Eclipse 3.2RC5 (was previously on RC2) and it works great!

[Riyad Kalla]

Glad it’s working, it’s amazing how little tiny API changes can cause something to break or work. I’ll let the guys know.
