[the goal]

This example is based on the previous example "simplest struts program" (see "How to implement the simplest Struts program"), its goal is to implement a radio box in the input page, displayed in the output page. The radio box is selected.

The project is expanded on the basis of the previous Simple project, and it is of course a new project.

[step]

1. Run JavaWebStudio to open the Simple project:

Select menu: "File" - "Open Project", select the simplest Struts program item Simple directory, open the project via Simple.PRJ project file.

2, open the helloword.jap file:

Open the helloword.jap file from the JavaWebStudio file manager, then switch to the toolbar, select the Struts tab, drag the "Radio Label" to the Code Edit window (or Web Visual Edit window).

Right-click on the code editing window: Select Refresh View, the Web Visual Edit window get refreshed.

3, join the bean variable:

In the Web Visual Edit window, the mouse light is shifted on one of the radio boxes and click the right mouse button, select "Add Bean Variable", add the bean variable of the variable name "Radio" (or right click in HelloWordform.java. Take the same operation):

The above "Add Bean Variable" operation is complete, and hellowordform.java automatically joins the SELECT variable and setRadio () and getradio () functions (code of the black body part).

Package EmptyPRJ;

Import javax.servlet.http.httpservletRequest;

Import org.apache.struts.Action.Actionerror;

Import org.apache.struts.Action.Actionerro;

Import org.apache.struts.Action.actionform;

Import org.apache.struts.action.actionmapping;

Public Final Class HelloWordForm Extends Actionform

{

PRIVATE STRING RADIO;

Private string mybeanvariable1;

Public string getMyBeanvariable11 ()

{

Return (this.mybeanvariable1);

}

Public void setMyBeanvariable1 (String MyBeanvariable1)

{

THIS.MYBEANVARIABLE1 = MyBeanVariable1;

}

Public void setradio (String newradio)

{

Radio = newradio;

}

Public String getradio () {

Return Radio;

}

}

Replenishing the code of the black body part in the HelloWord.jsp file (other code is automatically generated):
