EL comparison with equalIgnoreCase

Question

How to check equalIgnoreCase in EL?

String a = "hello";
a.equalsIgnoreCase("hello");

Now on JSP page..

<h:panelGroup rendered="#{patientNotePrescriptionVar.prescriptionSchedule ==  patientNotePresBackingBean.sendPrescription}">
            ... Some code here ....
</h:panelGroup>

Is there any way to compate patientNotePresBackingBean.sendPrescription as equalIgnoreCase?

Answer 1

If you're using EL 2.2 (part of Servlet 3.0) or JBoss EL, then you should be able to just invoke that method in EL.

<h:panelGroup rendered="#{patientNotePrescriptionVar.prescriptionSchedule.equalsIgnoreCase(patientNotePresBackingBean.sendPrescription)}">

If you're not on EL 2.2 yet, then your best bet is passing both strings through JSTL fn:toLowerCase() (or fn:toUpperCase()) and then comparing it.

<%@taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
...
<h:panelGroup rendered="#{fn:toLowerCase(patientNotePrescriptionVar.prescriptionSchedule) == fn:toLowerCase(patientNotePresBackingBean.sendPrescription)}">

Better, however, would be to not make them case sensitive. If they represent some kind of constants, better make them enums or something.
