Hi all, I have several questions about the deployment of a web application. Thanks for any help. 1. If I want to re-deploy the web application directly, I know that I just put the new war file in the "deploy" folder. It can re-deploy itself. My question is how about the transaction is handled during the deployment. Does JBoss AS 5.0 will wait all connection/request to finish first and then stop the new request; then do deployment. Please help to clarify the deployment flow. 2. If I use the other way to re-deploy the web application - undeploy it first and deploy it with the new version, how does JBoss handle the transaction/request during undeploy? 3. Also, if any user browse that web page in the stopped web application, they will 404 page not found. Is there other method/handling better to show the specific stopped web application is not available ( a message page )? Thanks in advance for anyone's help.
