RE: Form bean -> null

[Andres Marcel (KASO 211)]

Hi Konstantina,

How do you call your page? If you first call is not like ".do", then the action will 
not be invoked, therefore the form bean is not initialized.

Subject: Form bean -> null


Hello,
I need to use a  form bean  in struts and this is the first time I'm doing that .So as 
newbie I feel I'm missing something basic. Can U help me? This is my case.
I have my struts-config :

 <form-beans>
   <form-bean      name="MyForm" type="provider.test.MyForm"/>
</form-beans>


 <action    path="/editStream"
                type="provider.test.MyFormAction"
                name="MyForm"
                scope="request"
                validate="false">
      <forward name="success"              path="/streaming.jsp"/>
 </action>   


I have MyForm Bean with set and get methods and I have MyForm Action   which just 
initializes my form:


.........................

if (form == null) {
  
  System.out.println("Form is null");
            
     form = new MyForm();
            if ("request".equals(mapping.getScope()))
                request.setAttribute(mapping.getAttribute(), form);
            else
                session.setAttribute(mapping.getAttribute(), form);
 }
 MyForm strmform = (MyForm) form;

and finally my .jsp is the following:

<html:form action="/details" >
   <tr> <font size="5" color="#0000A0"> Destination IP Address : </font> 
        <html:text  property="ip1" size="3" /> <font color="#0000A0"> . </font>
        <html:text  property="ip2" size="3" /> <font color="#0000A0"> . </font>
        <html:text  property="ip3" size="3" /> <font color="#0000A0"> . </font>
        <html:text  property="ip4" size="3" /> <font color="#0000A0"> . </font>
   </tr>     
   <tr> <html:text  property="port" size="3" /> <font color="#0000A0"> </tr>
   <tr> <html:text  property="lan" size="3" /> <font color="#0000A0"> </tr>
   <tr> <html:text  property="autostart" size="3" /> <font color="#0000A0"> </tr>   
    
   
 </html:form>     


When I callthis page I get a :

javax.servlet.ServletException: Cannot retrieve definition for form bean null

error, and I cannot fingure out what I 'm doing wrong.

I would appriciated if U could provide me with any info regarding this problem.

Thank U in advance,
Konstantina
