Java Beans properties not recognized

Question

I'm trying to access a javabean property from jsp, but however this is what I get when I try to do so:
org.apache.jasper.JasperException: Cannot find any information on property 'PatientIcNo' in a bean of type 'Action.Profile'
my bean is Profile.java which is class in the package Action. I think i've compiled this successfully. But why am I still getting this error.
In my bean I've declared the getPatientIcNo() and setPatientIcNo() methods.
Thanks in advance.

Answer 1

But how did you declare patientIcNo?
private String patientIcNo;
or
private String PatientIcNo;
Believe it or not, it makes a difference.
Pay attention to the Java Bean Standard.
The JavaBean spec states that properties are case sensitive and start with a lower case character.
So in the JavaBean you should declare:
private String patientIcNo;
and the getter is:
public String getPatientIcNo() {
return patientIcNo;
In the JSP the syntax are:
<jsp:useBean id="patient" scope="request" class="Action.Profile" />
<jsp:setProperty name="patient" property="patientIcNo" value="RickyBobby" />
<jsp:getProperty name="patient" property="patientIcNo" />
<%= patient.getPatientIcNo() %>
<% patient.setPatientIcNo("Sidecar"); %>
If by chance you name the property PatientIcNo instead of patientIcNo,
<%= patient.getPatientIcNo() %>
and
<% patient.setPatientIcNo("Sidecar"); %>
work, but the others won't.
setPatientIcNo maps to the property patientIcNo.
But there isn't such a property in your bean!!
You named it PatientIcNo.
