Ava.lang.IllegalArgumentException: No bean specified

Question

config
<form-beans>
<form-bean name="FileUpload" type="roseindia.net.StrutsUploadForm"/>
</form-beans>
<action-mappings>
     <action path="/FileUpload" type="roseindia.net.StrutsUploadAction" name="FileUpload" scope="session" validate="true" input="/pages/FileUpload.jsp">
<forward name="success" path="/pages/uploadsuccess.jsp"/>
     </action>
     <action path="/popsup" type="roseindia.net.StrutsUploadAction" name="FileUpload" scope="session" validate="true" parameter="parameter" input="/pages/uploadsuccess.jsp">
<forward name="success" path="/pages/uploadsuccess.jsp"/>
     </action>
</action-mappings>
my first jsp is <B>FileUpload.jsp<B> like this
<html:form action="/FileUpload" method="post" enctype="multipart/form-data">
<html:file property="theFile"/>
<html:submit>Upload File</html:submit>
</html:form>
after clicking the Upload file button, the <B>uploadSuccess.jsp<B> looks like this
<html:form action="/popsup?parameter="show" method="post">
<html:select property="valueObj.id">
     <html:optionsCollection property="objectList" value="id" label="fullName" name="FileUpload"/>
</html:select>
<html:submit/>
</html:form>
The correspondin form beans are
public class StrutsUploadForm extends ActionForm
{ //assume all the methods are publlic
FormFile theFile;
ArrayList objectList;
valueObject valueObj;
FormFile getTheFile() {
return theFile;
void setTheFile(FormFile theFile) {
this.theFile = theFile;
void setValueObj(valueObject valueObj){
     this.valueObj = valueObj;          
valueObject getValueObj(){
     return this.valueObj;
void setObjectList(ArrayList objectList){
     this.objectList = objectList;
ArrayList getObjectList(){
     return this.objectList;
my value Object is
public class valueObject
String id;
String firstName;
String lastName;
String fullName;
valueObject(String id,String firstName,String lastName){
     this.id = id;
     this.firstName = firstName;
     this.lastName = lastName;
void setId(String id){
     this.id=id;
String getId(){
     return this.id;
void setFirstName(String firstName){
     this.firstName = firstName;
String getFirstName(){
     return firstName;
void setLastName(String lastName){
     this.lastName = lastName;
String getLastName(){
     return lastName;
getFullName(){
     return firstName+lastName;
and my action class is
public class StrutsUploadAction extends Action
public ActionForward execute(..){
StrutsUploadForm myForm = (StrutsUploadForm)form;
if(!"show".equals(request.getParameter("parameter"))){
valueObject v1 = new valueObject("3","Babu","Prasad");
     myForm.setValueObj(v1);
     ArrayList valueList = new ArrayList();
     valueList.add(new valueObject("1","vijay","ks"));
     valueList.add(new valueObject("2","Ram","Kumar"));
     valueList.add(v1);
     valueList.add(new valueObject("4","Raju","sundaram"));
     valueList.add(new valueObject("5","Kamal","Batch"));
     valueList.add(new valueObject("6","Ragu","varan"));
     myForm.setObjectList(valueList);
}else{
     System.out.println("myFORM OBJECTS "+myForm.getValueObj().getId());
return mapping.findForward("success");
But i try to select one of the value form the combo box and submit the uploadsuccess.jsp ,i am getting the following error

Could you give us the code of your JSP where you think things might go wrong ?
