To resolve, the Commons web server must be restarted. As the cause likely affects the other Commons web apps, restart them all.
Someone or something deleted the Commons application's unpacked war files.
Each Commons' application context xml file contains the element to unpack the war file. For Jetty, the location of the unpacked files is usually either
$(java.io.tmpdir). Reference: Jetty's Temporary Directories documentation.
Your jetty instance's startup command may not define
java.io.tmpdir or the
work subdirectory does not exist. If so, the usual location for the tmpdir is
/tmp. Many sysadmins regularly purge old files from
/tmp; this can then delete the unpacked files.
This in unlikely to happen with other web servers, such as Tomcat, since they do not by detault unpack to
Once the unpacked file(s) are deleted you will encounter the error(s) above.
Long Term Solution
The long term solution is to either:
- never delete the jetty unpacked war files under /tmp
- define an alternate location for the unpacked war
To define an alternate location:
- If your startup script does not define the jetty.home property, add
-Djetty.home=/path/to/jetty_home. Do this for each of the four Commons jetty instances' startup commands.
- Create the work subdirectory (
/path/to/jetty_home/work) with permissions allowing the jetty process owner full access to the directory. On restart, jetty will unpack to this new location.
A VM based on commons.ova assumes you will not be deleting the files in
/tmp so no action should be necessary. If you do need to move the files out of
/tmp, create the directory
/opt/jetty/work with permissions allowing user 'jetty' full access; the init.d startup scripts already define
jetty.home for you.
Sample unpacked war file directories on a commons.ova based VM:
root@dhcp-35-n101:/opt/jetty# ls -l /tmp/jetty*
