Serialize/Deserialize problem

2002-05-08 02:22

As I generate reports on a server and pass the results to a client I must serialize and deserialize the JasperPrint object.

 

Once deserialized, newline characters have been damaged; when viewing the report I can see little squares and no line break where the newline character was. Prior to serializing the JasperPrint it views ok.

 

Here is how I serialize and deserialize it:

 

ByteArrayOutputStream out = new ByteArrayOutputStream();

ObjectOutputStream objectOut = new ObjectOutputStream(out);

objectOut.writeObject(jasperPrint);

 

ByteArrayInputStream in = new ByteArrayInputStream(out.toByteArray());

ObjectInputStream objectIn = new ObjectInputStream(in);

JasperPrint jasperPrint = (JasperPrint) objectIn.readObject();

 

Is there any workaround to this problem; could I do some kind of substitution on the bytes to correct the newlines before (or after) deserializing?

 

Thanks

John
