Hello everybody,
I'm new in struts technology and I wanted try a simple struts example, but it didn't work. Here are listings of code:
*** struts-config .xml (is located in WEB-INF/) :
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.0//EN"

<struts-config>
<form-beans>
<form-bean name="registerForm" type="app.RegisterForm"/>
</form-beans>
<action-mappings>
<action path="/register"
type="app.RegisterAction"
name="registerForm">
<forward name="success" path="/success.html"/>
<forward name="failure" path="/failure.html"/>
</action>
</action-mappings>
</struts-config>
*** RegisterAction.java (located in WEB-INF/classes/app):
package app;
import org.apache.struts.action.*;
import javax.servlet.http.*;
import java.io.*;
public class RegisterAction extends Action {
public ActionForward perform(ActionMapping mapping, ActionForm form,
HttpServletRequest req, HttpServletResponse res) {
// b Cast the form to the RegisterForm
RegisterForm rf = (RegisterForm) form;
String username = rf.getUsername();
String password1 = rf.getPassword1();
String password2 = rf.getPassword2();
// c Apply business logic
if (password1.equals(password2)) {
return mapping.findForward("success");
}
// E Return ActionForward for failure
return mapping.findForward("failure");
}
}
*** RegisterForm.java (located in WEB-INF/classes/app):
package app;
import org.apache.struts.action.*;
public class RegisterForm extends ActionForm {
protected String username;
protected String password1;
protected String password2;
public String getUsername() {return this.username;};
public String getPassword1() {return this.password1;};
public String getPassword2() {return this.password2;};
public void setUsername(String username) {this.username = username;};
public void setPassword1(String password) {this.password1 = password;};
public void setPassword2(String password) {this.password2 = password;};
}
