struts+Action+netbeans 5.0 problem
Hi all
I am trying to use struts with netbeans 5.0 but having strange problems.
I have wrtten One ActionForm i.e EmployeeForm ,one action i.e AddEmpAction.
then in the struts-config.xml provided following entries:
form-bean type=com.myapp.struts.forms.EmployeeForm name=employee/
action input=/addEmployee.jsp type=com.myapp.struts.actions.AddEmpAction
validate=false scope=session path=/addemp name=employee
forward path=/index.jsp name=success/
/action
and using /addEmployee.jsp as welcomefile.
But when i run my application it is displaying the addemployee.jsp correctly
but when i click on the submit button it just displays a blank screen showing
addemp.do in the address bar.
can anybody provide what i am missing.
the listing of my formbean and action class is following.
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
/**
*
* @author admin
*/
public class AddEmpAction extends Action{
public ActionForward excecute(ActionMapping mapping,ActionForm
form,HttpServletRequest request,HttpServletResponse response){
try{
System.out.println(inside
action**);
EmployeeForm empForm=(EmployeeForm)form;
String name=empForm.getName();
float salary=empForm.getSalary();
String address=empForm.getAddress();
Employee emp=new Employee(name,salary,address);
EmployeeDao dao=new EmployeeDao();
dao.insertEmployee(emp,1);
}
catch(Exception e){
e.printStackTrace();
}
return mapping.findForward(success);
}
}

It might sound stupid, but just check: Your execute method from Action is

having problem Using Indexed properties with Multi select inside logic iterate
Hi i am trying to use a multi select box in logic iterate
in this way
logic-el:iterate indexId=ctr id=admindepartment
name=admindepartments
html-el:select property=bookMapped(${ctr}) multiple=true
size=2
html-el:options name=bean property=dbBookType/
/html-el:select
/logic-el:iterate
in the form bean i have following code.
private Map selectedBooks;
public Object getBookMapped(String index) {
return selectedBooks.get(key);
}
public void setBookMapped(String index,Object value) {
selectedBooks.put(key,value);
}
now in each multiple select box i am selecting
multiple books but in the resulting map selectedBooks
i am getting one value for each multiple selection
then i had also tried using
public void setBookMapped(String index,Object[]
value) {
selectedBooks.put(key,value);
}
but which is throwing an illegelargumenttype
exception.
please help.
thanks in advance.
