init in interface javax.servlet.Servlet

Overrides:

init in class EChartsProxyServlet

Throws:

javax.servlet.ServletException

specifyRequestURI

protected URI specifyRequestURI(SipServletRequest request)

Obtains forwarding URI from interface and continues the call. The headers and contents of the original request are copied to the forwarded request.

Overrides:

specifyRequestURI in class EChartsProxyServlet

Parameters:

request - initial request

Returns:

desired Request-URI, or null for no change

sessionCreated

public void sessionCreated(SipApplicationSessionEvent ev)

For SipApplicationSessionListener interface.

Specified by:

sessionCreated in interface SipApplicationSessionListener

sessionDestroyed

public void sessionDestroyed(SipApplicationSessionEvent ev)

For SipApplicationSessionListener interface.

Specified by:

sessionDestroyed in interface SipApplicationSessionListener

sessionExpired

public final void sessionExpired(SipApplicationSessionEvent sase)

For SipApplicationSessionListener interface. This is required as a work-around for SailFin bug. This method is enabled by setting the javaee:listener-class tag value in sip.xml, otherwise it will be ignored.

Specified by:

sessionExpired in interface SipApplicationSessionListener

sessionReadyToInvalidate

public void sessionReadyToInvalidate(SipApplicationSessionEvent ev)

For SipApplicationSessionListener interface.

Specified by:

sessionReadyToInvalidate in interface SipApplicationSessionListener
