Identifying the application deployment on server start up and actual deployment by the user

Hi All,

Am deploying a web application with a servlet context listener, which does database insertions on deployment and deletions on undeployment. After deploying the application if i restart the server the servlet context listener again tries to insert the records in database. But these insertions and deletions should be done only when the user deploys or undeploys the application and not on server start up or shutdown.

Is there any way to identify :

1. The application deployment on server start up and actual deployment of the application by user after start up.

2. The application undeployment on server shutdown and actual undeployment of the application by user.

Regards,

Vedanth

Hmm. In both cases it's a normal deployment. One option would perhaps to be a management client to check the status of the AS (perhaps it's "starting" when booting and "running" when deploying) or perhaps checking if the application is available at point of deployment). Why don't you just check from the DB if the rows are present and skip insert in that case?
