public void activate(org.osgi.framework.BundleContext bundleContext)

Description copied from class: AbstractWebConsolePlugin

Specified by:

activate in interface org.apache.felix.webconsole.internal.OsgiManagerPlugin

Overrides:

activate in class SimpleWebConsolePlugin

Parameters:

bundleContext - the context of the plugin bundle

deactivate

public void deactivate()

Description copied from class: SimpleWebConsolePlugin

This method will close all service trackers, created by SimpleWebConsolePlugin.getService(String) method. If you override this method, don't forget to call the super.

Specified by:

deactivate in interface org.apache.felix.webconsole.internal.OsgiManagerPlugin

Overrides:

deactivate in class SimpleWebConsolePlugin

doGet

protected void doGet(javax.servlet.http.HttpServletRequest request,
                     javax.servlet.http.HttpServletResponse response)
              throws javax.servlet.ServletException,
                     IOException

Description copied from class: AbstractWebConsolePlugin

Renders the web console page for the request. This consist of the following five parts called in order:

1. Send back a requested resource
2. AbstractWebConsolePlugin.startResponse(HttpServletRequest, HttpServletResponse)
3. AbstractWebConsolePlugin.renderTopNavigation(HttpServletRequest, PrintWriter)
4. AbstractWebConsolePlugin.renderContent(HttpServletRequest, HttpServletResponse)
5. AbstractWebConsolePlugin.endResponse(PrintWriter)

Note: If a resource is sent back for the request only the first step is executed. Otherwise the first step is a null-operation actually and the latter four steps are executed in order.

If the AbstractWebConsolePlugin.isHtmlRequest(HttpServletRequest) method returns false only the AbstractWebConsolePlugin.renderContent(HttpServletRequest, HttpServletResponse) method is called.

Overrides:

doGet in class AbstractWebConsolePlugin

Throws:

javax.servlet.ServletException

IOException
