Hi,

I just created a .mspec to materialize a target platform using a feature cquery. A rmap resolves the components from a local folder and the galileo site. I'm pretty confident that I setup everything
correctly because I can export this to a p2 update site from the IDE using "Resolve to wizard/export as p2". I can also run the buckminster headless to materialize, works as expected.

The strange thing is:
Whenever I execute the exact same configuration as user 'tomcat6' I get a very strange error message (I boiled down the example from a failing Hudson build). The file permissions for the local folders
/ the buckminster headless installation are correct. I'm running this on Ubuntu 9.10). Any ideas about this?

Again, the exact same configuration works when executed as different user, the whole /opt/buckminster/ folder is owned by tomcat6.
What's going on here?

I think this is a permission problem of some folder I'm not aware of...
The only google result I'm getting when searching for this error message is some russian guy having the same problem running on Linux when installing software using "Install new software":

Found it, all glory to strace.

Home folder of the tomcat6 user is configured to be /usr/share/tomcat6 on Ubuntu.

/usr/share/tomcat6 is owned by root by default and not writable.

buckminster tries to create a folder .buckminster in there:

..buckminster/
`-- repository
`-- http
`-- download.eclipse.org
|-- 9591a3fa-76b1-3b26-8e98-7380c8027901
`-- 9591a3fa-76b1-3b26-8e98-7380c8027901.properties

I propose improving that particular error message:

"Server returned HTTP response code: 503 for URL:
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"

to be

"Could not write to /usr/share/tomcat6/.buckminster"

:)
