Andy Seaborne resolved JENA-179.
--------------------------------
Resolution: Not A Problem
Assignee: Andy Seaborne
Suggestions for better ways to start the server very welcome, ideally the same
as a regular web container manages the situation.
> On Linux Fuseki will create user owned temporary files that block other users
> from using the full Fuseki Web UI

> 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
> Assignee: Andy Seaborne
>
> 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.
