public enum TheEnum {
	LOCALE_BASENAME("value1");

	private final String value;
	private TheEnum(final String value) {
		this.value = value;
	}
	public String toDbValue() {
		return value;
	}
}

Need to use page directive to import enum class:

<@page import="mylib.myenums.TheEnum">

<c:if test="${'value1' eq TheEnum.LOCALE_BASENAME.toDbValue()}">
</c:if>
