Method Detail

contextInitialized

public void contextInitialized(javax.servlet.ServletContextEvent servletContextEvent)

Specified by:

contextInitialized in interface javax.servlet.ServletContextListener

contextDestroyed

public void contextDestroyed(javax.servlet.ServletContextEvent servletContextEvent)

Specified by:

contextDestroyed in interface javax.servlet.ServletContextListener

configure

protected abstract void configure()

Define this method to configure bindings at servlet context initialization. Call AbstractModule.install(Module) within this method to use binding code from other modules.

Specified by:

configure in class AbstractDwrModule

getStage

protected com.google.inject.Stage getStage()

Override this method to specify which stage to run Guice in. Default behavior is to look first in user preferences and then in system preferences for node "org/directwebremoting/guice" with a value for key "stage". If not found, the default is Stage.PRODUCTION.

getServletContext

protected javax.servlet.ServletContext getServletContext()

Subclasses can use this during stage determination and binding to read values from the current servlet context.
