I'm getting serialization errors when I attempt to run the
ParserDemo.java example.
 
Outputting status messages to standard out.
ca.uhn.hl7v2.util.Status: Standard status messages will be output.

Here is the source..
 
import ca.uhn.hl7v2.parser.*;
import ca.uhn.hl7v2.model.Message;
import ca.uhn.hl7v2.model.v24.message.ACK;
 
public class ParserDemo {
    
    public static void main(String args[]) {
        //for demo purposes, we just declare a literal message string 
        String ackMessageString 
            =
"MSH|^~\\&|foo|foo||foo|200108151718||ACK^A01^ACK|1|D|2.4|\rMSA|AA\r";
        
        //instantiate a PipeParser, which handles the "traditional
encoding" 
        PipeParser pipeParser = new PipeParser();
        
        try {
            //parse the message string into a Message object 
            Message message = pipeParser.parse(ackMessageString);
            
            //if it is an ACK message (as we know it is),  cast it to an

            // ACK object so that it is easier to work with, and change
a value            
            if (message instanceof ACK) {
                ACK ack = (ACK) message;
 
ack.getMSH().getProcessingID().getProcessingMode().setValue("P");
            }
            
            //instantiate an XML parser 
            XMLParser xmlParser = new DefaultXMLParser();
            
            //encode message in XML 
            String ackMessageInXML = xmlParser.encode(message);
            
            //print XML-encoded message to standard out
            System.out.println(ackMessageInXML);
        } catch (Exception e) {
            e.printStackTrace();
        }       
    }
}
 
 
Thanks for any help.
