[jboss-jira] [JBoss JIRA] Closed: (BPEL-223) Convert IntegrationServlet to a servlet context listener

Convert IntegrationServlet to a servlet context listener -------------------------------------------------------- Key: BPEL-223 URL: http://jira.jboss.com/jira/browse/BPEL-223 Project: JBoss jBPM BPEL Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Engine Reporter: Alejandro Guizar Assigned To: Alejandro Guizar Fix For: jBPM BPEL 1.1 beta 3 ServletContextListeners are a viable alternative to servlets for initializing and destroying the integration control. From the Servlet 2.4 spec, section 10.2: "Servlet event listeners support event notifications for state changes in the ServletContext, HttpSession and ServletRequest objects. Servlet context listeners are used to **manage resources** or state held at a JVM level for the application." Their intent definitely seems to match our purposes. Section 10.2.2 provides an example. When the application starts up, the listener creates a connection to the database and stores it in the servlet context. Servlets access the connection from the context as needed. When the application shuts down, the listener closes the connection. Our listener could initialize the integration control and store it in the servlet context, then destroy it.
