I’m running a pretty old version of Red hat Linux. I just installed 7.5 and have a problem with startup. It tells me to select an external browser because it’s having trouble opening the start page. I’ve checked tha preferences and it has the external browser set to the system default. I can view help, which it opens in the external browser. The MyEclipse Start Page tabl displays the message:

Could not open the editor: An unexpected exception was thrown.

When I look at details, I see the following:

vgriffin,
Can you copy paste your installation details from MyEclipse > Installation Summary > Installation Details?
How did you install MyEclipse? Did you use all-in-one installer/pulse explorer/installed eclipse classic 3.4.1 and added MyEclipse plugin?

[Loyal Water]

vgriffin,
Could you also let us know whether you are working on the 32 bit or 64 bit linux?

[vgriffin]

I took it out so I could get some work done and have reinstalled 7.5 to get the info. It got the error when it came up on installation. Here are the details. (When I asked to view the error log, it didn’t do anything.) I’m running the 32-bit all-in-one and used a completely “fresh” directory this time.

vgriffin,
Can you switch to a new workspace and check if the issue persists?

[vgriffin]

I already tried that. It does.

I am also getting this error. It will not show the start page. I could probably live with that but after I restart about three times the preferences screen where I need to go to set the external browser comes up completely empty except for a tiny square on top left corner.

I am working on 64 bit Red Hat (interestingly enough I am being forced to use 32 bit java env. so I am running the 32 bit all in one installer)

I tried setting an external browser as /usr/bin/firefox which is where firefox is located. Firefox is also on the path so just typing firefox at the command prompt would also work. mozilla is also on the path btw.

I have tried going to Help -> Software Updates -> Check for Updates, and I get the following message:

Check for Updates… could not validate the system configuration. Your installation appears to be misconfigured due to a missing active profile definition.

Is this perhaps related to the internal/external browser issue?

[support-shalini]

michaelagrouse, vgriffin,
Are there any errors in the log file located at workspace dir > .metadata > .log?
Can you send the screenshots, error log file as PM/mail to support@genuitec.com, mention subject as ATTN:Shalini and refer to this thread.

[Riyad Kalla]

vgriffin,

The issue is most likely a platform conflict with the native XUL Runner libraries (Mozilla) we ship in order to render the Start Page (it’s actually a web page). That version of XUL Runner is built against a relatively modern version of Linux and it’s possible that while MyEclipse is able to load the XUL Runner libraries, there is some mismatch occuring between the XUL Runner libraries and the platform itself. Unfortunately I don’t have a workaround for you at this time.

michaelagrouse,

That sounds like a GTK/SWT rendering glitch. When that happens, try and resize the window slightly to force it to repaint itself — it should look fine after you do that.

[vgriffin]

In other words, 7.1 is as new a version of MyEclipse as I can use. I absolutely recognize that a vendor can only support reasonably-current software. We already know that this version of Linux doesn’t work with FireFox 3.

Thank you for your time.
