Method Detail

activate

public void activate(org.osgi.framework.BundleContext bundleContext)
Description copied from class: AbstractWebConsolePlugin
This method is called from the Felix Web Console to ensure the AbstractWebConsolePlugin is correctly setup. It is called right after the Web Console receives notification for plugin registration.

Specified by:
activate in interface OsgiManagerPlugin
Overrides:
activate in class AbstractWebConsolePlugin
Parameters:
bundleContext - the context of the plugin bundle
See Also:
AbstractWebConsolePlugin.activate(org.osgi.framework.BundleContext)

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 OsgiManagerPlugin
Overrides:
deactivate in class SimpleWebConsolePlugin
See Also:
SimpleWebConsolePlugin.deactivate()

printConfiguration

public void printConfiguration(java.io.PrintWriter pw)
Description copied from interface: ConfigurationPrinter
Prints the configuration report to the given printWriter. Implementations are free to print whatever information they deem useful.

Specified by:
printConfiguration in interface ConfigurationPrinter
Parameters:
pw - where to write the configuration data. It might be flushed, but must not be closed.
See Also:
ConfigurationPrinter.printConfiguration(java.io.PrintWriter)

doGet

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

Overrides:
doGet in class AbstractWebConsolePlugin
Throws:
