Deployment Script for Webcenter Application

Oracle WebCenter Portal applications differ from traditional Java EE applications in that they support run-time customization. WebCenter Portal application customizations are stored in Oracle Metadata Services (MDS), which is installed in a database/file. So, while deploying the webcenter application on WLS, you need to  specify the metadata repository and the partition in the repository that application will be deployed to.
As far as I know, targeting the application to MDS repository deployment is not possible using the wldeploy ant task. WLST commands can be used  to target the application to MDS repository and deploy the application on WLS. So, first create a python script and then call it from the ant script.

Here is the script deploy.py -

# Below args are passed by the ant script
adminUser=sys.argv[1]
adminPassword=sys.argv[2]
adminUrl=sys.argv[3]
# Connect to WLS
connect(adminUser,adminPassword,adminUrl)
domainRuntime()

# Stop the application
def stop():
 stopApplication(sys.argv[6])

# Undeploy the applciation
def undeployApp():
 print 'Begin undeploy'
 undeploy(sys.argv[6])
 print 'End undeploy'

# Deploy the application
def deployApp():
 print 'Begin deployAll'
 serverConfig()
 # Returns a handle to the MDSArchiveConfig object for the specified archive 
 archive = getMDSArchiveConfig(fromLocation=sys.argv[4])
 # Sets the connection details for the application metadata repository
 archive.setAppMetadataRepository(repository=sys.argv[5],partition=sys.argv[6],
 type=sys.argv[7], jndi=sys.argv[8])
 archive.save()
 deploy(appName=sys.argv[6], path=sys.argv[4], targets=sys.argv[9], upload='true')
 
 print 'End deployAll' 

# Start the application 
def start(): 
 startApplication(sys.argv[3])
 
# Deploy script init- First Stop the application and then undeploy. 
#After undeploying, deploy the application and restart

try:
 try:
  stop()
 except:
  print sys.exc_info()[0]
 print 'Stop Done'
 try:
  undeployApp()
 except:
  print sys.exc_info()[0]
 print 'Undeploy Done'
 deployApp()
 start()
 
except:
 print 'Unexpected error: ', sys.exc_info()[0]
 dumpStack()
 raise
