Question

Hello I am trying to deploy my grails application to my newly installed jetty instance. I installed jetty on ubuntu 12.04 with apt-get install jetty and it’s running completely fine under port 8080.

Then I tried to deploy my small grails application by compiling it to a war-file and moving it to the standard jetty_home/webapps folder and restart jetty. Now the problem begins, whenever I go to my context path in the browser I get this:

HTTP ERROR: 503

Problem accessing /hello. Reason:

    SERVICE_UNAVAILABLE

When I check the jetty logs it is almost completely empty except some logging errors?

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I can’t get it to run my application which is just a hello-world app (I’ve tried with my real app before also). At first I thought it was because of openjre on the deployment machine but then I tried to compile it with openjdk and it still has the same results.

I have also tried to set the hello.war file under the jetty:abs user via chown command. The root app is deployed just like this and I see no reason why my app shouldn’t work.

I’ve checked some threads to see if my installation process is wrong somehow but I can’t find any solution. There is no other errors logged. If I use cat 2013_01_29.stderrout.log it’s empty. Please help me find a solution to my problem, I just want my app up and running asap.

Thanks!

EDIT:

Okay, I downloaded the jar file recommended and now I got some exception about permission denied on my applicationContext. I am still unsure how to continue since I’m kind of confused. I guess this means that jetty don’t have the permission required to write in /var/cache/jetty ?

It looks like you don’t have write permission to unpack the war file – it’s failing to write /var/cache/jetty/data/Jetty_0_0_0_0_8080_hello.war__hello__.yjv6m1/webapp/WEB-INF/applicationContext.xml. The java.io.FileNotFoundException is confusing but the
“Permission denied” message is telling you the real problem.

Either grant yourself write permission under the /var/cache/jetty/data/ directory, or run Jetty as a user that has write permission, or change the directory where Jetty expands war files to a location you can write to.
