Overrides:

init in class EChartsProxyServlet

Throws:

javax.servlet.ServletException

handleInitialRequest

protected boolean handleInitialRequest(SipServletRequest req)
                                throws javax.servlet.ServletException,
                                       java.io.IOException

Parameters:

req - initial request

Returns:

Whether request handling is completed

Throws:

javax.servlet.ServletException

java.io.IOException

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.

sessionExpired in interface SipApplicationSessionListener

sessionReadyToInvalidate

public void sessionReadyToInvalidate(SipApplicationSessionEvent ev)

For SipApplicationSessionListener interface.

Specified by:

sessionReadyToInvalidate in interface SipApplicationSessionListener
