Deployment Race Condition with Tomcat

• Key: JS2-199
• Type: Bug
• Status: Closed
• Resolution: Fixed
• Priority: Critical
• Assignee: Ate Douma
• Reporter: John Donald
• Component/s: Deployment
• Affects Version/s: 2.0-dev/cvs

Description

The deployment of portlets and the deployment of Tomcat conflict.

Step 1: Tomcat starts and looks for webapps
Step 2: Tomcat finds jetspeed.xml and initializes the application
Step 3: Jetspeed starts the DeploymentManager
Step 4: The DeploymentManager finds the demo portal application and begins to deploy it using manager.xml
Step 5: Tomcat continues looking for webapps and finds webapps/demo which has been created by Jetspeed
Step 6: Tomcat initializes the demo webapp
Step 7: The DeploymentManager continues and tries to register /demo through the tomcat-manager
Step 8: Error: /demo has already been deployed.

This happens obviously also when autodeploy is set to false.
Tomcat is just not finished its standard deployment, when it is interrupted by the JS-DeploymentManager.

It's critical, because when this happens to the security webapp you cannot login.

I've added the output I get when starting from scratch.

See http://issues.apache.org/jira/browse/JS2-210.
Deployment has been completely rewritten and this problem cannot occur anymore.
