Hi Kedar,
    here is the JSPDyn page code
package com.lti.portal;
//import bean.myBean;
import com.lti.portal.FirstBean;
import com.sapportals.htmlb.*;
import com.sapportals.htmlb.enum.*;
import com.sapportals.htmlb.event.*;
import com.sapportals.htmlb.page.*;
import com.sapportals.portal.htmlb.page.*;
//import com.sap.htmlb.page.PageException;
import com.sapportals.portal.prt.component.*;
public class Practs_JSPcomp extends PageProcessorComponent {
  public DynPage getPage(){
    return new Practs_JSPcompDynPage();
  public static class Practs_JSPcompDynPage extends JSPDynPage{
     private final static int INITIAL_STATE = 0;
        private final static int WELCOME_STATE = 1;
        private int state = INITIAL_STATE;
        private String name;
    private FirstBean myBean = null;
    public Practs_JSPcompDynPage()
          this.setTitle("Start");
    public void doInitialization(){
      IPortalComponentRequest request= (IPortalComponentRequest) this.getRequest();
       IPortalComponentContext myContext = request.getComponentContext();
      IPortalComponentProfile myProfile = myContext.getProfile();
      //new bean object
       FirstBean UserNameContainer= new FirstBean();
       //Set name
       UserNameContainer.setName("UNKNOWN USER");
       //Store bean in profile for JSP
       myProfile.putValue("myBean",UserNameContainer);
       //setting the state.
       state= INITIAL_STATE;
    public void doProcessAfterInput() throws PageException {
         //get the input from JSP
          InputField myInputField = (InputField) getComponentByName("user_name_input");
          if (myInputField != null) {
               this.name = myInputField.getValueAsDataType().toString();
          IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
          IPortalComponentContext myContext = request.getComponentContext();
          IPortalComponentProfile myProfile = myContext.getProfile();
          FirstBean myNameContainer = (FirstBean) myProfile.getValue("MyNameBean");
          myNameContainer.setName(name);
    public void doProcessBeforeOutput() throws PageException {
          switch (state) {
                         case WELCOME_STATE :
                                   this.setJspName("Practs_JSPFile.jsp");
                    break;
                    default :
                              this.setJspName("Practs_JSPFile.jsp");
                         break;
     public void onSendButtonClicked(Event event) throws PageException {
                state = WELCOME_STATE;
& here is d JSP code
<hbj:content
     id="myContext" >
       <hbj:page
            title="Start">
             <hbj:form
                  id="myFormId" >
               <%Declaration Of Bean%>
               <jsp:useBean
               id="myBean"
               scope="application"
               class="bean.FirstBean" />
                   <hbj:textView
                id="welcome_message"
                design="HEADER1">
                <%
                  welcome_message.setText
                  ("May the force be with you "+myBean.getName());
                %>
              </hbj:textView>
            <br>
            <br>
            <hbj:label
                id="label_input"
                text="Your name please"
                design="LABEL"
                required="TRUE"
                labelFor="user_name_input"
                />
   <%-- inputfield to allow userinput - the inputfield has the id --%>
   <%-- "user_name_input" which is used in the JSP DynPage to     --%>
   <%-- access the input field and retrieve the input of the user --%>
            <hbj:inputField
                id="user_name_input"
                type="STRING"
                design="STANDARD"
                width="250"
                maxlength="30"
             />
             <hbj:button
                id="Send_Button"
                text="Send"
                tooltip="Sends my name"
                onClick="onSendButtonClicked"
                width="100"
                design="EMPHASIZED">
                <%
                    myFormId.setDefaultButton(Send_Button);
                %>
               </hbj:button>
             </hbj:form>
       </hbj:page>
</hbj:content>
