[news.eclipse.dtp] Datatools Install/Uninstall Problems

[geoff.roberts@xxxxxxxxxxxxxx (Geoffry Roberts)]

All,

There have been a few similar posts recently that seem to center on the 
topic of install/uninstall problems wrt the set of datatools so I thought 
I'd weigh in as well.  I too am having problems.

Here's my question:
If I go in and delete the dtp related features and plug ins manually, will 
I break anything else?

I tried to install the plugin for Google Web Toolkit 1.6 using their 
update site and got the following error:

An error occurred while collecting items to be installed
Error closing the output stream for
org.eclipse.datatools.sqldevtools.data.feature/
org.eclipse.update.feature/1.6.2 ... The error message it goes on, full 
text of the output is below.

I tried to uninstall dtp and got similar errors. So, I can't even get rid 
of dtp.
