Question

I am a novice in struts and I have been trying to build a simple struts application. I have errors which I have been trying to resolve for the past couple of days but unable to solve it. The following are the files that I have used-

web.xml

    <?xml version="1.0" encoding="ISO-8859-1"?>

    <body>
        Welcome!!!!!!!!

        <bean:write name="myForm" property="st"/>
    </body>
</html>

myForm.java(Bean class)-

package com;

public class myForm extends org.apache.struts.action.ActionForm {

    private String st;

    public String getSt()
    {
        return st;
    }

    public void setSt(String st)
    {
        this.st=st;
    }

    public myForm(String st)
    {
        this.st=st;
    }
}

myAction.java(Action class)-

package com;

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;
import com.myForm;

public class myAction extends Action {
    public ActionForward execute(ActionMapping mapping, ActionForm form,
    HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException {

        myForm form1=(myForm) form;

        String s="Karthikeyan";

        form1.setSt(s);

        //RequestDispatcher reqDispatcher = getRequestDispatcher("view.jsp");
        //reqDispatcher.forward(request,response);




        return (mapping.findForward("success"));
    }
}

When I compile myAction.java, it gives the following error-

myAction.java:11: cannot find symbol
symbol  : class myForm
location: package com
import com.myForm;
          ^
myAction.java:18: cannot find symbol
symbol  : class myForm
location: class com.myAction
                myForm form1=(myForm) form;
                ^
myAction.java:18: cannot find symbol
symbol  : class myForm
location: class com.myAction
                myForm form1=(myForm) form;
                              ^

Also, when I run the tomcat server, I get the following errors-

org.apache.commons.digester.Digester error
SEVERE: Parse Error at line 9 column 43: Element type "bean" must be declared.

and

org.apache.commons.digester.Digester error
SEVERE: Parse Error at line 10 column 15: The content of element type "form-beans" must match "(form-bean)*".

Please help me.

Was it helpful?

Solution

you wrote the wrong struts-config.xml, you should change form-beans as below format:

    <form-beans>
        <form-bean name="myForm" type="com.myForm"></form-bean>
    </form-beans>
