Method Detail

init

public void init()
          throws javax.servlet.ServletException

Override the init method to load the init of stxx stuff

Throws:

javax.servlet.ServletException - If something goes wrong

reload

public void reload()
            throws java.io.IOException,
                   javax.servlet.ServletException

Override the reload method to load the init of stxx stuff

Throws:

java.io.IOException - If something goes wrong

javax.servlet.ServletException - If something goes wrong

destroyApplication

protected void destroyApplication()

Override the destroyApplication object to destroy the stxx objects

processActionForward

protected void processActionForward(ActionForward forward,
                                    org.apache.struts.action.ActionMapping mapping,
                                    org.apache.struts.action.ActionForm form,
                                    javax.servlet.http.HttpServletRequest request,
                                    javax.servlet.http.HttpServletResponse response)
                             throws java.io.IOException,
                                    javax.servlet.ServletException

Overrides the struts process ActionForward method to trap for transformation that need to be done. If there is no transform, then process the forward as usual. Otherwise, process the transform

Parameters:

forward - - An ActionForward object

mapping - - An ActionMapping

form - - An ActionForm

request - - The request object

response - - The response object

Throws:

java.io.IOException - - If an error occurs, throw it

javax.servlet.ServletException - - If an error occurs, throw it

initDigester

protected Digester initDigester(int detail)

Override the initDigester of the main struts class to add functionality for supporting transform tags in the tag

Parameters:

detail - - The level of debugging detail to use

Returns:

The digester

process

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

Since I cannot override the process method, I've just copied the contents here. The reason I cannot remove this is that since I've overridden methods like processActionForward and processActionPerform, just calling super.process would run all the super.processAction* methods. This would be bad and make things not work. I don't know if I have any other options.

Parameters:

request - - The request object

response - - The response object

Throws:

java.io.IOException - - If an error occurs, throw it

javax.servlet.ServletException - - If an error occurs, throw it

processValidate

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

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

Returns:

True if valid

Throws:

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

javax.servlet.ServletException - if a servlet exception occurs
