Dear friends,

I have this problem spoiling my development.
I have written the following JSP in NetBeans 5.5.1

<%@ page language = "java" %>
<%@ taglib uri = "/WEB-INF/struts-tiles.tld" prefix = "tiles" %>
<%@ taglib uri = "/WEB-INF/struts-html.tld" prefix = "html" %>
<%@ taglib uri = "/WEB-INF/struts-logic.tld" prefix = "logic" %>
 
<html:html>
    <head>
        <title>First Struts Application</title>
    </head>
    <body>
       <html:form name="lookUpForm" type="my.servercomp.practice.lookupForm" action="Lookup.do">
        <table width="500" border="0" cellspacing="0" cellpadding="0">
            <tr>
                <td> </td>
            </tr>
            <tr bgcolor="#36566E">
                <td height="68" width="48%"> 
                    <div align="left">
                        <img src="C:\Documents and Settings\168825\Desktop\2RowRedBarBG3.jpg" width="220" height="74">
                        </div>
                </td>
            </tr>
            <tr>
                <td> </td>
            </tr>
       </table>
    
       <table width="45%" border="0">
            <tr>
                <td>Symbol:</td>
                <td><html:text property = "symbol" /></td>
            </tr>
            <tr>
                <td colspan="2" align="center"><html:submit value="Submit"/></td>
            </tr>
      </table>
    </html:form>
</body>
</html:html>

Following is the Form class:

Following is the Action class:

package my.servercomp.practice;
 
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
 
public class LookupAction extends Action
{
    protected Double getQuote(String symbol)
    {
        if(symbol.equalsIgnoreCase("SUNW"))
        {
            return new Double(25.00);
        }
        return null;
    }
    
    public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
    {
        Double price = null;
        // Default target to success
        String target = new String("success");
        if (form != null) 
        {
            // Use the LookupForm to get the request parameters
            lookupForm lookForm = (lookupForm)form;
            String symbol = lookForm.getSymbol();
            price = getQuote(symbol);
        }
        // Set the target to failure
        if (price == null) 
        {
            target = new String("failure");
        }
        else 
        {
            request.setAttribute("PRICE", price);
        }
        // Forward to the appropriate View
        return (mapping.findForward(target));
    }
}

The following are the entries in struts-config.xml:

When i deploy the JSP, i am getting this error:
org.apache.jasper.JasperException: Unable to find setter method for attribute: name

So friends, kindly provide your patience to go through this problem and help me get out of the pit.

Thanks in advance,
Vijay

Other than in your struts form tag, I don't see anyplace in your JSP where you would be trying to set a name property.
I would start by going through stack traces in the logs to see if there is a line number in either the JSP or the generated servlet code where you can go for more hints.

Since this is a Struts project and since you aren't getting any help here, I'm going to move this to our Struts forum.

I believe NetBeans uses Struts 1.2.9. In this version of struts, the name and type attributes of the <html:form> tag are deprecated. Just remove them, and your page should work fine. They aren't really necessary anyway as you've already defined this information in your struts-config.xml file.
