Hi Luciano, It seems to me that the problem arises when the Tuscany runtime is loading the contribution file. You can find more logging at [0]. As you can see there are two things logged with info level before the error:
1. I 08-19 11:19AM 41.228 2. org.apache.tuscany.sca.node.impl.NodeImpl start: Starting node: 1.344198860972114123 domain: default 3. I 08-19 11:19AM 41.229 4. org.apache.tuscany.sca.node.impl.NodeFactoryImpl loadContributions: Loading contribution: file:/base/data/home/apps/tuscany-comet/1.344198860972114123/ The same file ID appears in the "Access denied" error. This makes me think the root of the problem would be on how Tuscany is reading the contribution file although the GAE environment allows reading, only writing is not allowed. That is the reason why I brought it up on the mailing list as I expected you to have hit this problem before...
