Hi All,
I am trying to use Taverna 2.4.1 server to run a workflow.
I am running Taverna Server under Tomcat 6.0.37 on a Ubuntu/Linux OS.
I am accessing the Taverna Server via the REST interface with the server
running in 'insecure' mode.
The workflow that I am running can be uploaded to the Taverna server fine.
I can start and run the workflow via the REST.
I can also check the workflow status.
When the workflow status is 'Finished', I invoke a GET on the Taverna server to
retrieve XML file containing the output file paths.
I do this by GETting the following URL:-
http://localhost:8443/taverna-server/rest/runs/UUID/wd/out
Where UUID is a long character string for the current session ID.
If I open the path http://localhost:8443/taverna-server/rest/runs/UUID , I see
an XML document with path tags like <ts-rest:input />, <ts-rest:output/>.
Input XML, creation time XML etc are all available and valid.
If I access any of the output paths for a given session however, either by Java
REST client or the firefox web browser, Taverna server returns a HTTP 403 error
code and the message 'problem getting main directory handle'.
This output path function were working earlier today but something has
corrupted with the Taverna Server system state and I do not know what.
I have tried re-starting the Tomcat server and the error persists.
If I run any workflow, I cannot access any of the output as the output
directories are not being published by the Taverna server.
Any advice on how to resolve this issue would be most appreciated.
I will try undeploying the Taverna server but I would rather have an idea on
the root cause.
Many thanks in advance,
Gareth
