Unable to get values of form fields using FormBean using Struts

[advan]

Hi,

I am new to Struts 1.2.x wish to have immediate help on the following issue.

Issue : Unable to get values of form fields using FormBean using Struts

Details :
----> JSP page having 3 fields Cityname, state name and country name. having HTML tags as follows :

<form action=""../CityAction.do?action=submitCityMasterData"" name="form2" method="post">

------> Input type line
<input type="button" value="Submit" class="g_button" onclick="createCity()" />

-----------
On submit following javascript function is called :

<script> function createCity(){ alert("create City - submit is called") var is = validatePage(); if(is==0){ // var goToServlet='<%=PageMappings.CITY_MASTER_SUBMIT_CI TY_ACTION%>'; //window.location=goToServlet; document.form2.submit(); } } </script>


----------------------------------------
struts-config.xml file has following entries for beans and mappings :

<form-beans>
<form-bean name="cityMasterFormBean" type="com.buhariwalas.app.form.cityMaster.CityMast erFormBean"/>
</form-beans>

<action-mappings>
</action>
<action path="/CityAction"
type="com.buhariwalas.app.action.cityMaster.CityAc tion"
parameter="action"
scope="request"
name="cityMasterFormBean">
</action>

--------------------------

can anyone tell me why the following code in SubmitCityAction.java prints null values :

public class SubmitCityAction {
private ActionForward nextPage = null;
private CityMasterFormBean cityForm = null;
/*-----------------------------------------------------------------------*/
public ActionForward submitCityMasterData(ActionMapping mapping, ActionForm form,
HttpServletRequest request,HttpServletResponse response){

private CityMasterFormBean cityForm = null;

cityForm = (CityMasterFormBean)form ;

System.out.println("City Form Values = "+
"\ncity = "+cityForm.getCity_name()+","+
"\nstate = "+cityForm.getState_name()+","+
"\ncountry = "+cityForm.getCountry_name() );


nextPage = mapping.findForward("mainPage");

return nextPage;
}
}

Can you try to make it without java script?

Can you try to make it without java script?

And with Code Tags next time around?

[advan]

even without Javascript i.e. submit() called from input type submitt button also resulted in the same way.

Following is the partial error log printed in my console.

[Petr]

There are snippets, which you posted is correct. Hence can you show the full code? That we can testing it.

Please find all the code as files mentioned below in ZIP file attached.

SubmitCityAction.java
CityAction.java
CityMasterFormBean.java
CityMaster_Create.jsp
struts-config.xml
CityMasterDao.java

[advan]

Is I am missing in DAO file ???

[Petr]

)) How you think how Struts need understand what variables from jsp to due with variables from form bean?
