Method Detail

init

public void init(ModuleManager manager,
                 java.util.HashMap<java.lang.String,java.lang.Object> settings)
          throws ModuleException

Description copied from interface: Module

Initialises the module. After constructor, this is the first method called in the life cycle of a module. It should not perform anything time consuming or anything with notable outside side effects. It should only read the parameters and initialise the module so that it can later be started. Note that a module being initialised doesn't mean that it necessarily will ever be started.

A ModuleException may be thrown if something vital is missing from the parameters or they are not sensible. In some cases you may not want to throw an exception even if vital initialisation information is missing. If, for example, it is possible that the module is initialised in some other way between the init and the start method calls. A ModuleException may also be thrown at the start method if the module is still not initialised.

Specified by:

init in interface Module

Overrides:

init in class AbstractWebApp

Parameters:

manager - The module manager handling this module. You may keep a reference to it if needed.

Throws:

ModuleException

handleAction

public boolean handleAction(javax.servlet.http.HttpServletRequest req,
                            javax.servlet.http.HttpServletResponse resp,
                            ModulesServlet.HttpMethod method,
                            java.lang.String action,
                            User user)
                     throws javax.servlet.ServletException,
                            java.io.IOException,
                            ActionException

Description copied from class: AbstractAction

Handles this action. Prior to calling this action, it's already been determined that this action should try to handle the action by either matching the action request parameter with the action id of this action, or this being the default action. Perform any operations needed here and then write the response into the response object. You will typically want to call setHttpHeaders to set the HTTP headers in the response after you know that you definitely will handle the request but before you write anything else into the response stream. If for whatever reason this method shouldn't handle the request after all, return false. Otherwise return true.

Specified by:

handleAction in class AbstractAction

Parameters:

req - The HTTP Request.

resp - The HTTP response.

method - The HTTP method of the request.

action - The parsed action id.

user - The logged in user, or null if not applicable.

Returns:

True if the action was handled and a response sent. False otherwise in which case other actions may try to handle this action.

Throws:

javax.servlet.ServletException

java.io.IOException

ActionException
