All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

Deprecated. Tiles now uses ActionServlet with TilesPlugin and TilesRequestProcessor.

public class ActionComponentServlet

extends ActionServlet

Action Servlet to be used with Tiles and Struts 1.0.x. For Struts 1.1, use TilesPlugin and eventualy TilesRequestProcessor. This servlet extends struts one. It adds channels and screens dispatching capabilities. We overide all methods that do request forward (i.e. 'processActionForward' and 'processValidate') in order to call a new method performing forward. In fact, we copy methods to overide, and change lines doing forward which now call 'processForward()'. Rest of the method is unchanged. This new method could now be overiden in order to dispatch request before forwarding. Compliant to ActionServlet from struts 2001/06/25 00:02:27

Method Detail

init

public void init()
          throws javax.servlet.ServletException

Deprecated.

Init method. This method is call on any servlet.

Overrides:

init in class ActionServlet

Throws:

javax.servlet.ServletException - if we cannot configure ourselves correctly

public void initComponentDefinitionsMapping()
                                     throws javax.servlet.ServletException

Deprecated.

Read component instance mapping configuration file. This is where we read files properties.

javax.servlet.ServletException

processActionForward

protected void processActionForward(ActionForward forward,
                                    ActionMapping mapping,
                                    ActionForm formInstance,
                                    javax.servlet.http.HttpServletRequest request,
                                    javax.servlet.http.HttpServletResponse response)

                                    javax.servlet.ServletException

Deprecated.

Overload struts1.0 counterpart in order to catch forward calls. This is an exact copy, except the call to RequestDispatcher.forward() replaced by doForward(). This method is only used with Struts1.0.x Forward to the specified destination, by the specified mechanism, if an ActionForward instance was returned by the Action.

Parameters:

forward - The ActionForward returned by our action

mapping - The ActionMapping we are processing

formInstance - The ActionForm we are processing

request - The servlet request we are processing

response - The servlet response we are creating

Throws:

java.io.IOException - if an input/output error occurs

javax.servlet.ServletException - if a servlet exception occurs

processValidate

protected boolean processValidate(ActionMapping mapping,
                                  ActionForm formInstance,
                                  javax.servlet.http.HttpServletRequest request,
                                  javax.servlet.http.HttpServletResponse response)
                           throws java.io.IOException,
                                  javax.servlet.ServletException

Deprecated.

Overload struts1.0 counterpart in order to catch forward calls. This is an exact copy, except the call to RequestDispatcher.forward() replaced by doForward(). This method is only used with Struts1.0.x Call the validate() method of the specified ActionForm, and forward back to the input form if there are any errors. Return true if we should continue processing (and call the Action class perform() method), or return false if we have already forwarded control back to the input form.

Parameters:

mapping - The ActionMapping we are processing

formInstance - The ActionForm we are processing

request - The servlet request we are processing

response - The servlet response we are processing

Throws:

java.io.IOException - if an input/output error occurs

javax.servlet.ServletException - if a servlet exception occurs

Deprecated.

Overload struts1.0 counterpart in order to catch forward calls. This is an exact copy, except the call to RequestDispatcher.forward() replaced by doForward().
