7.  Adding code to the server application 

This chapter describes most of the code that the e FixIT application wizard includes in the server 

application objects it creates. It also presents several useful methods, events and properties. 

7.1  Application events 

You can add application events by selecting 

this

 object (see picture in chapter 6.5), clicking 

Events

 tab in 

the panel right and double clicking on the event. 

7.1.1  Action event 

The server application object has a few events defined that do not appear in Delphi/Web FixIT. The most 

important is 

action

 event, which occurs when 

call(String fileNumber)

 method of the application is 

called from the 

application

 JSP script (see chapter 5). The action event is best used to create logic that 

responds to the end user clicking submit/image buttons on the form. 

For example, when the user clicks 

First

 (<<) button on the HTML form, an key/value pair of 

 action=<< 

 is set (i.e, 

setAction( << )

) is called on the server application. When the call method is 

placed, the server application forwards the operation to corresponding source component, which is 

connected to the FileMan database file described by 

fileNumber

 parameter in the call method header. 

Thus the HTML form reloads to show the first record of the file. 

The call method processing can be influenced by adding an 

action

 event to the server application. For 

example, the intercepting code could look like this: 

  void this_action(ActionEvent e) { 

   if (e.getAction().equals("<<")) { 

    // do some stuff here 

    e.consume(); 

   }  

Now the event code 

consumes

 the event and the source component will not receive the operation. 

The 

action

 event can also be used to add custom events: You can define a submit button such as 

and intercept the button in the 

action

 event. 

The e FixIT Application wizard creates a default action event for the server application object.
