Access Enum value using EL with JSTL

Question

I have an Enum called Status defined as such:

public enum Status { 

    VALID("valid"), OLD("old");

    private final String val;

    Status(String val) {
        this.val = val;
    }

    public String getStatus() {
        return val;
    }

}

I would like to access the value of VALID from a JSTL tag. Specifically the test attribute of the <c:when> tag. E.g.

<c:when test="${dp.status eq Status.VALID">

I'm not sure if this is possible, so any help would be much appreciated.

Answer 1

A simple comparison against string works:

<c:when test="${someModel.status == 'OLD'}">

Answer 2

For this purposes I do the following:

<c:set var="abc">
    <%=Status.OLD.getStatus()%>
</c:set>

<c:if test="${someVariable == abc}">
    ....
</c:if>

It's looks ugly, but works!

Answer 3

I generally consider it bad practice to mix java code into jsps/tag files. Using 'eq' should do the trick :

<c:if test="${dp.Status eq 'OLD'}">
  ...
</c:if>
