Package org.sigpath.action Description

Controller classes for the Struts model-view-controller (MVC) pattern.


Controller classes control the overall flow of the web application. In general, a browser request first goes to the generic SigPathServlet, which then forwards the request to the appropriate action class. The action class generally calls one or more database tasks, and passes the results onto a Java Server Page (JSP). HTML formatting is done within the JSP page.

Creating New Actions Classes

All new action classes should extent ActionRoot. Action Root centralizes all live debugging, setting of user messages and exception handling. To create a new action, simply extend ActionRoot and implement the _perform() method. For example:
public class DeleteExternalReference extends ActionRoot {

  protected ActionForward _perform
    (ActionMapping mapping, ActionForm form, HttpServletRequest request,
    HttpServletResponse response, ActionForward actionForward, XDebug xdebug)
    throws Exception {
      xdebug.logMsg(this, "Starting Action:  Delete External Reference");

Warning: The Struts framework will only create one instance of your Action class, and this one object will serve multiple browser requests. Therefore, you must avoid using instance variables within your Action class. Otherwise, you may end up with unpredictable multi-threading issues.

Modifying the struts-config file

Once you have created a new action class, you must register it in the struts-config.xml file. For example:
<action path="/deleteExternalReference"

Controlling Access

If you want to restrict access to your action class, you can specify one or more access control interfaces: For example, to create an action that is available only to the SigPath administrator, you would write the following code:
  public class ChangeDBStatus extends ActionRoot implements SecureAdmin {
