Hi,
I am trying to do the following,
I have one CommonForm which extends DynaValidatorForm
The i have a DispatchAction class which populates the
value for CommonForm and stores it is request and then
forwards it to a jsp,
Then in the jsp i have defined a bean with request
scope, and then use the bean to display value in text
field
But I am getting "Null pointer exception" while
loading this page,
I am giving below all the snippets of my code please
help
my form definiation
public class CommonForm extends DynaActionForm
implements Serializable
{
private String input1;
public void setInput1(String input1)
{
this.input1 = input1;
}
public String getInput1()
{
return this.input1;
}
}
then in my DispatchAction class i do the following
CommonForm commonForm = new CommonForm();
commonForm.setInput1("This is test");
request.setAttribute("PL1820UpdateForm", commonForm);
this is my jsp code
<jsp:useBean id="PL1820UpdateForm"
class="com.pfizer.maps.form.CommonForm"
scope="request">
</jsp:useBean>
<html:hidden name="PL1820UpdateForm" property="input1"
write="true"/>
But if i do
System.out.println(PL1820UpdateForm.getInput1() );
I get the value
