Hi, all. Iam new to struts. As a part of starting my journey towards struts, I started with a simple struts application. But I am facing problem with either actionForm or actionClass or someother. Here is entire application. Please go through this and help me.

My application location : C:\Tomcat 5.5\webapps\myStruts (In this, My application name is myStruts.)
Contents of myStruts folder : WEB-INF folder, First.jsp, Second.jsp.

C:\Tomcat 5.5\webapps\myStruts\First.jsp code
==============================================
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>

<html:html>
<head>
<title>First.jsp</title>
</head>
<body>
<html:form action="/first.do">
<html:errors />
<table>
<tr>
<td>Enter Your Nick Name: </td>
<td><input type="text" name="nick" /></td>
</tr>
<tr>
<td>Enter Your Lucky Number: </td>
<td><input type="text" name="lucky" /></td>
</tr>
<tr>
<td></td>
<td align="right"><input type="submit" value="Submit" /></td>
</tr>
</table>
</html:form>
</body>
</html:html>

C:\Tomcat 5.5\webapps\myStruts\Second.jsp code
================================================
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>

<html:html>
<head>
<title>Second.jsp</title>
</head>
<body>
<html:errors />
<p><h2>Hai, you are redirected from First.jsp</h2></p>
</body>
</html:html>

Contents of myStruts/WEB-INF folder :
actionForms folder (contains FirstActionForm.java, FirstActionForm.class),
actions folder (contains FirstAction.java, FirstAction.class),
classes (empty) folder,
lib (containing jar files) folder, and
xml files (struts-config, web, tiles-defs, validation, validator-rules).

C:\Tomcat 5.5\webapps\myStruts\WEB-INF\actions\FirstAction.java code
==========================================================================
import javax.servlet.http.*;
//import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.*;
//import org.apache.struts.action.ActionForm;
//import org.apache.struts.action.ActionForward;
//import org.apache.struts.action.ActionMapping;

public class FirstAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
System.out.println("This is from Action class");
return mapping.findForward("success");
}
}

C:\Tomcat 5.5\webapps\myStruts\WEB-INF\actionForms\FirstActionForm.java code
=============================================================================
import org.apache.struts.action.*;
import javax.servlet.http.HttpServletRequest;


public class FirstActionForm extends ActionForm{

private String nick = null;
private String lucky = null;

public String getNick() {
return nick;
}

public String getLucky() {
return lucky;
}

public void setNick(String nick) {
this.nick = nick;
}

public void setLucky(String lucky) {
this.lucky = lucky;
}

public void reset(ActionMapping mapping, HttpServletRequest request) {
this.nick=null;
this.lucky=null;
}

}

Actually you didn't mention the error details. So it is quite difficult to guess.
But i am thinking you may have mistake in thse lines.
use only one tag library bcz you are using only html tags so
<%@ taglib uri="/tags/struts-html" prefix="html" %> is enough.
Then instead of using this <html:form action="/first.do"> tag use only <html:form action="first.do"> no "/" slash is required bcz you are mentioning clearly first.do
use <html:text property="nick"/> instead of <input type="text" name="nick" />, bcz you are using struts specific html tags.

in struts-config.xml file just modify like below

<action-mappings>

<action
path="first.do"
name="formbean1"
type="actions.FirstAction"
validate ="false">
<forward name="success" path="/Second.jsp"/>
</action>

</action-mappings>

Try it. It may solve your problem.
