BlobTypeHandlerCallback doesn't support Null-Values
---------------------------------------------------

                 Key: IBATIS-432
                 URL: https://issues.apache.org/jira/browse/IBATIS-432
             Project: iBatis for Java
          Issue Type: Bug
          Components: SQL Maps
    Affects Versions: 2.1.7
         Environment: all
            Reporter: Sebastian Radics


Setting of Null for Blobs results in Error-Message:
At least one parameter to the current statement is uninitialized with derby.

Fix:
Method BlobTypeHandlerCallback#setParameter:

public void setParameter(ParameterSetter setter, Object parameter)
throws SQLException {
   if (null != parameter) {
     byte[] bytes = (byte[]) parameter;
     ByteArrayInputStream bis=new ByteArrayInputStream(bytes);
     setter.setBinaryStream(bis,(int)(bytes.length));
   }else{//NEW - handle null-Values - Use Sql-Type BLOB
	   setter.setNull(Types.BLOB);
   }
 }
