Hi,

I'm working through the Working With Web Projects - Quickstart tutorial. When I get to the part where I create a new JSP I get an error that says: "Unable to create this part due to an internal error. Reason for the failure: An unexpected exception was thrown." Any ideas about what is causing this or how to correct?

Thanks.

Here's my configuation information:

Windows XP SP2
Eclipse SDK 3.1.1 Build id: M20050929-0840
MyEclipse Version: 4.1.1 Build id: 20060228-4.1.1-GA
Eclipse and MyEclipse were already installed. I ran the update manager to upgrade to ME 4.1.1 from 4.0.8

<SNIP>

What version of IE do you have o nyour machine? MyEclipse relies on version 6.x, if you have version 5 or version 7 beta that is most likely the problem.

I have Internet Explorer 6.0.x installed. I'm going to try a clean reinstall of Eclipse and MyEclipse this weekend. I'll let you know what happens.

Thanks.

--Joe

Joe,

Do you have any versions of MS Office or MS Visual Studio installed? For office did you install Frontpage as well?

Yes, I have Microsoft Word 2000 (9.0.2720) installed.

--Joe

Sorry, too quick with the Enter key.

I have the whole dang MS Office Professional 2000 suite installed including MS Access. I don't have MS Visual Studio or FrontPage installed.

--Joe

OK, I just did a clean reinstall of Eclipse 3.1.2 and MyEclipse 4.1.1. Here's the new configuration info:

Did you try a clean workspace as well? (File > Switch Workspace > C:\tempworkspace, hit OK) NOw create a new web project with a HTML file and try and open it, did it wokr? Now try a JSP file, did it work?

Right click on the file and go to Open With and make sure they are associated with the "MyEclipse HTML Designer" and "MyEclipse JSP Designer" respectively.

Thanks for replying on a Sunday.

I just tried a clean workspace, as you suggested. I got the same error when I tried to create a new HTML file. And again when I tried to create a new JSP. Here's something new though. If I right-click on either the HTML file or the JSP and select open with->MyEclipse 'Classic' HTML Editor or MyEclipse 'Classic' JSP Editor, then the files open up just fine. Looks like the problem is in the engine that runs the MyEclipse HTML or JSP Designer editor.

--Joe

Joe,
This does sound like there is something on your system (we have seen Office, Visual Studio and IE Beta all break the new designer) that is making it mad. Can you run with the "Classic" editor in the mean time while we look into this?

Riyad,

It's no problem at all for me to use the Classic editors. I know that MS Office Pro 2000 is pretty old, but I just hate handing Bill Gates another big wad of cash if I can avoid it. Thanks again for your help.

--Joe

I don't blame you Joe, have you tried Open Office? I've been able to switch all my work to Open Office 2.0 without anyone else noticing... it's my own little way of saying "Thanks, but I'd rather keep my $500".

I just wanted to give you an update. I uninstalled MS Office 2000 Professional and installed OpenOffice. I started MyEclipse, created a new workspace, new Web project, new JSP, and got the same error as before. I can still use the classic JSP editor, but not the new JSP designer. Hope this helps narrow down the problem.

--Joe

Joe,
I had a good opportunity to talk with management about this and the designer team and they are investigating a much more robust designer architecture right now and making good headway that will hopefully do away with the designer being so sensative to platform changes. Thank you for the feedback, we collect all of it for the developers.

and what is the response ? I've had a broken visual editor for at least 4 weeks now ? Is there a timeline for fixing this ?
