Jython script to automate websphere deployment

I am trying to develop a jython script to automate the websphere deployment. I am trying to deploy to a cluster with two nodes. I was able to stop, uninstall and start cluster. but my 'install' step is not working. I have another script to stop the cluster.so this is performed after stopping the cluster. Here is my install step I am using in my script:

print AdminApp.install[apppath, '[-appname '+appfile+' -cell '+cell+' -cluster '+cluster+' -MapModulesToServers '+map_modules_cluster+' -MapWebModToVH '+map_modules_vh+']']

 map_modules_cluster='[ sample.war Sample.war,WEB-INF/web.xml WebSphere:cell=HostnameCell01,cluster=AdminCluster+WebSphere:cell=HostnameCell01,node=HostnameNode01,server=webserver1]'

map_modules_vh=default_host
