create your enum class in the following format. public class SortingTypes implements java.io.Serializable { private java.lang.String _value_; private static java.util.HashMap _table_ = new java.util.HashMap(); // Constructor protected SortingTypes(java.lang.String value) { _value_ = value; _table_.put(_value_,this); } public static final java.lang.String _ASC = "ASC"; public static final java.lang.String _DESC = "DESC"; public static final SortingTypes ASC = new SortingTypes(_ASC); public static final SortingTypes DESC = new SortingTypes(_DESC); public java.lang.String getValue() { return _value_;} public static SortingTypes fromValue(java.lang.String value) throws java.lang.IllegalArgumentException { SortingTypes enumeration = (SortingTypes) _table_.get(value); if (enumeration==null) throw new java.lang.IllegalArgumentException(); return enumeration; } public static SortingTypes fromString(java.lang.String value) throws java.lang.IllegalArgumentException { return fromValue(value); } public boolean equals(java.lang.Object obj) {return (obj == this);} public int hashCode() { return toString().hashCode();} public java.lang.String toString() { return _value_;} public java.lang.Object readResolve() throws java.io.ObjectStreamException { return fromValue(_value_);} } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3984265#...
