war application deployement on geronimo failing

I followed the tutorial given here http://www.ibm.com/developerworks/opensource/library/os-ag-wsvs/ and wrote a grails application helloworld.

The tutorial is given here http://grails.org/doc/1.0.x/ and documentation to deply is here. https://cwiki.apache.org/GMOxDOC20/deployer-tool.html and https://cwiki.apache.org/GMOxDOC20/installing-and-removing-applications.html

I do not have a GUI access to the server machine I am working on is a Mac and via an SSH connection accessing the grails machine. Web based admin control panel to deploy war on the above said machine had failed since I used it in this format 7 http://192.168.1.13:9090

I had changed default port to run.

So to select war application it asked me to upload from my mach machine. Which was not there.Hence I used the script deploy.sh

from

/geronimo-jetty7-javaee5-2.2/bin# ./deploy.sh deploy /root/a12/target/a12-0.1.war 

I got following error

2010-05-03 03:42:28,012 ERROR [DeployTool] Error:

I had even used redeploy but got following error

Have checked a link about a possible bug http://apache-geronimo.328035.n3.nabble.com/Deployment-says-module-already-exists-even-though-it-does-not-td339229.html but the said folder does not exist on my

geronimo_home/repository

What should I look at?
