Re: [Jetty-support] Problems with webapps that have complex startup procedures

[Ryan P. <ry...@vi...>]

Well, the deployment is done during jetty's startup procedure with no implicit customizations.  So I assume that it is the webapp deployer.

The extra initialization is in the primary servlet for the webapp.

Ryan,
  
  How are you deploying the webapp - context deployer or webapp deployer?
  Where does the initialization get done, is it a context listener, or in
  a servlet?
