Below I have tried to give you solution that you want. It would be helpful if you explain your exact requirement?
[1] define your attibute formhandler
//your XXXFormHandler.java
package a.b.c;
public class XXXFormHandler extends GenericFormHandler{
     String name;
     String successURL;
     String errorURL;
     //anyogher property(ies)
     //getters and setters
     //handler method
     public boolean handleDoIt(DynamoHttpServletRequest pRequest, DynamoHttpServletResponse pResponse)throws ServletException, IOException{
          preDoIt(pRequest,pResponse);
          //your operation goes here
          postDoIt(pRequest,pResponse);
          return return checkFormRedirect(getSuccessURL(), getErrorURL(), pRequest, pResponse);
     void preDoIt(DynamoHttpServletRequest pRequest, DynamoHttpServletResponse pResponse)throws ServletException, IOException{
          if(getName()==null||getName().IsEmpty()){
               addFormException(new DropletException("name should not be null"));
          //other varification goes here
     void postDoIt(DynamoHttpServletRequest pRequest, DynamoHttpServletResponse pResponse)throws ServletException, IOException{
               //code you want to do after handle method operation goes here
     //other code .............     
[2] make component config/a/b/c/XXXFormHandler.properties:
$class=a.b.c.XXXFormHandler
$scope=request
[3]use dsp:form in page1.jsp
page1.jsp:
<dsp:form action="" method="post">
     //print error message
     <dsp:droplet name="Switch">
          <dsp:param name="value" bean="XXXFormHandler.formError"/>
          <dsp:oparam name="true">
               <dsp:droplet name="ProfileErrorMessageForEach">
                    <dsp:param name="array" bean="XXXFormHandler.formExceptions"/>
                    <dsp:oparam name="outputStart">
                         <ul>
                    </dsp:oparam>
                    <dsp:oparam name="output">
                         <tr><td><li><font color="red"><dsp:valueof param="message"/></font></li></td></tr>
                    </dsp:oparam>
                    <dsp:oparam name="outputEnd">
                         </ul>
                    </dsp:oparam>
               </dsp:droplet>
          </dsp:oparam>
     </dsp:droplet>
     <dsp:input type="text" bean="XXXFormHandler.name">
     //set error/success urls
     <dsp:input type="hidden" bean="XXXFormHandler.successURL" value="page1.jsp"/>
     <dsp:input type="hidden" bean="XXXFormHandler.errorURL" value="page2.jsp"/>
     <dsp:input type="submit" bean="XXXFormHandler.doIt" value="Send"/>
</dsp:form>-RMishra
