Hi, Is getResult() being called? If not, try adding an explicit javaType="java.util.UUID" to the resultmap.
If I may suggest an optimization: replace getter.getObject() == null with getter.wasNull().

I follow this example http://opensource.atlassian.com/confluence/oss/display/IBATIS/How+do+I+u se+a+Custom+Type+Handler+with+complex+property+or+Type+Safe+Enumeration and created my TypeHandler. In my person class, I have the following: public class Person { UUID id; //get and set method... } and in UUIDTypeHandler: public class UUIDTypeHandler implements TypeHandlerCallback{ public Object getResult(ResultGetter getter) throws SQLException { String value = getter.getString(); if(getter.getObject() == null){ return null; } UUID uuid = UUID.fromString(value); return uuid; } public void setParameter(ParameterSetter setter, Object parameter) throws SQLException { if(parameter == null){ setter.setNull(Types.VARCHAR); }else{ UUID uuid = (UUID) parameter; //System.out.println(uuid.toString()); setter.setString(uuid.toString()); } } public Object valueOf(String s) { return s; } } in the sqlmapconfig I added this: <typeHandler javaType="java.util.UUID" callback="domain.UUIDTypeHandler"/> I tried to do a select query, but the result is always null, is there something else I am missing? -- View this message in context: http://www.nabble.com/TypeHandler-UUID-tf3264136.html#a9073293 Sent from the iBATIS - User - Java mailing list archive at Nabble.com.
