Rob Vesse updated JENA-179:
---------------------------

other users from using the full Fuseki Web UI (was: On Linux Fuseki will
create user owned temporary files that block other users from running Fuseki
instances even after the Fuseki instance has been stopped)
Updated title to more accurately reflect the issue

> Key: JENA-179
> URL: https://issues.apache.org/jira/browse/JENA-179
> Project: Jena
> Issue Type: Bug
> Components: Fuseki
> Environment: SUSE Linux 11
> Reporter: Rob Vesse
>
> Fuseki seems to create temporary files under Linux which are owned by the
> running user and blocks any other users from running Fuseki properly because
> servlets will not function correctly.
> Going to the control panel will produce the following trace:
> Error 500: /tmp/org/apache/jsp/control_002dpanel_jsp.java (Permission denied)
> java.io.FileNotFoundException: /tmp/org/apache/jsp/control_002dpanel_jsp.java

> It looks like these temporary files are being generated by one of the
> components Fuseki relies upon rather than Fuseki itself but this is an issue
> for us because if one user has run Fuseki another user may be completely
> blocked from using the web based UI fully.
> Interestingly servlets will still function correctly, e.g. I can still issue
> queries directly to /dataset/query and get a response but the lack of a
> control panel is inconvenient.
> This may not be fixable due to it actually being caused by a component that
> Fuseki depends upon but I have no expertise in Jetty/JSP/Servlets so I don't
> know against what project this bug should actually be filed.
