Easy way:
--------
You can always use the "unstandard" tags. Works great for me:
<un:bind type="com.company.project.Const" field="SOME_CONST" var="yourVar"/>
<c:if test="${$yourVar == 'some value'}">
<c:out value="${yourVar}"/>
</c:if>
Not so easy way:
---------------
(by Kris Schneider on taglib-users)
Put something like this in a startup servlet or a plug-in:
public static Map getConstantFieldsAsMap(Class cls)
throws IllegalAccessException {
Field[] allFields = cls.getDeclaredFields();
int numFields = allFields.length;
Map propMap = new HashMap(numFields);
for (int i = 0; i < numFields; i++) {
Field f = allFields[i];
int mods = f.getModifiers();
if (Modifier.isPublic(mods) &&
Modifier.isStatic(mods) &&
Modifier.isFinal(mods)) {
String name = f.getName();
Object value = f.get(null);
propMap.put(name, value);
}
}
return Collections.unmodifiableMap(propMap);
}
In JSP:
<c:set var="responseMap"
value="${applicationScope['javax.servlet.http.HttpServletResponse']}"/>
SC_NOT_FOUND: <c:out value="${responseMap.SC_NOT_FOUND}"/>
