Symlinks in the deploy directory?

[david_xplana]

Hey everyone,

I'm quite unfamiliar with JBoss, and I have a quick question. Is is possible to use symlinks in the deploy directory under linux? I would like users to be able to keep all their packages under their home directories and simply create symlinks from the deploy directory.

When I try to create a symlink to a war file (test.war -> /home/user/test.war), the following appears in the log file:

DEBUG [org.jboss.deployment.scanner.URLDeploymentScanner] Failed to deploy: ... file:/usr/jboss/jboss-4.0.0/server/default/deploy/test.war could not be opened, does it exist?

Is it a permissions problem, or simply not possible? Any help on this is greatly appreciated.

Dave.

It looks ok to me. I created a link to a /tmp/test.war and that deploys fine:

[starksm@lamia deploy]$ ls -l test.war
lrwxrwxrwx 1 starksm starksm 13 Dec 2 11:55 test.war -> /tmp/test.war/

...
11:56:27,186 INFO [TomcatDeployer] deploy, ctxPath=/test, warUrl=file:/cvs/Releases/jboss-4.0.0/server/symlink/deploy/test.war/

I was able to access this using http://localhost:8080/test/. I did see this suprious warning, but it does not affect the web app behavior so I would say its just a permission issue.

Thanks a lot Scott. I'm ashamed, all the permissions on the home directories were set to 700. Wow.

[wiley173]

So this error should just be ignored, is there a way to get rid of it ?

I edited the jboss-service.xml instead of symlinks...

 <attribute name="URLs">
 deploy/,
 file:/home/wiley173/
 </attribute>

my hellowWorld.war seems to work fine but this error ???

Is this just an error with how I set up my .war file?

[wiley173]

I moved the .war outside of my "jboss" user directory wiley173 and it went away ...

[starksm64]

Your URLs list is poorly choosen as it includes a directory which includes the entire server distribution. This will recursively scan all directories under /home/wiley173/ looking for deployable content.

[wiley173]

Yeah, I found that one out after starting jboss and watching the output for an hour

-thanks happy christmas !

How do you specify this on a Windows machine.

This is what I have, and I'm getting the same zip errors
