Read an Object that is Serialized

Question

Hi All,
I am trying to read back in a file that has been serialized and created by ObjectOutputStream.
So I am using Object Input Stream.
The catch is this file was created with a call to a class that does a List, which calls another class.
How can I read this file back? The List part is throwing me off.
Any examples or help would be great.
Here is my try statement:
FileInputStream inFile = null;
ObjectInputStream input = null;
try{
inFile = new FileInputStream("RDD_BeamPositionTrackReportMessage.bin");
input = new ObjectInputStream (inFile);
//deserialize the List
BeamPositionTrackReportMessage test = (BeamPositionTrackReportMessage)input.readObject();
I want to read the whole file.
Thanks
Tim

Hi,
Here is my samples:
ReportMessage.java
import java.util.*;
import java.io.*;
public class ReportMessage implements java.io.Serializable
public List bPTR = new ArrayList();
Which is used with TrackReport.java:
mport java.util.*;
public class TrackReport implements java.io.Serializable{
          long MessageCreationTime;
          int ActivityID;
          float Reserved_1;
          int BeamNumber;
          float Reserved_2;
          int ScanCount;
          long MeasurementTime;
          int ActivityType;
So basically my serialized log looking for ReportMessage Class and not TrackReport Class which has all the variables.
So then I have a java program called ReadFile.java
ile file = new File("TrackReportMessage.log");
FileInputStream fileInputStream = new FileInputStream(file);
BufferedInputStream bufferedInputStream = new BufferedInputStream(fileInputStream);
ObjectInputStream objectInputStream = new ObjectInputStream(bufferedInputStream);
BeamPositionTrackReport beamobject = (TrackReport)objectInputStream.readObject();
Maybe I am confused, but with the ReadFile.java I want to read the TrackReport, but some how need to go through ReportMessage first. Basically the List is being Serialized.
Hope this makes more sense.
Thanks
