Folks,
I am relatively new to HAPI.
Please help me extending HAPI for the custom Z Segment.
The message that i have is:

99999999999";
In this, i have one segment "ZCC".
I could successfully extend "AbstractSegment" to create this particular
segment.
But when i am trying to get the values from field(1), i don't get any
results or null results.
I then tried creating a new DataType having three fields of Type SI. But i
still had the same problem.
Can somebody throw some pointers on where i have been doing wrong.
The code that i have is:
import ca.uhn.hl7v2.HL7Exception;
import ca.uhn.hl7v2.model.AbstractSegment;
import ca.uhn.hl7v2.model.Group;
import ca.uhn.hl7v2.model.Message;

import com.etipl.v23.datatype.ZDT;
public class ZCC extends AbstractSegment{
/**

private static final long serialVersionUID = -1837490858393615628L;
public ZCC(Group parent, ModelClassFactory factory) {
super(parent,factory);
Message message = getMessage();
try {
this.add(ZDT.class, true, 4, 60, new Object[]{message});
}
catch(HL7Exception hl7e) {
System.out.println("Can't instantiate");
}
}
public ZDT getDetails() {
ZDT ret = null;
try {
Type t2 = this.getField(1,0);
ret = (ZDT)ret;
} catch (ClassCastException cce) {
throw new RuntimeException(cce);
} catch (HL7Exception he) {
throw new RuntimeException(he);
}
return ret;
}
