Yes, I did. The code snippet was in my original posting. I am including it here
again for the folks out there -
try
{
Marshaller marshaller = new Marshaller(writer);
marshaller.setSuppressXSIType(true);
marshaller.setValidation(true);
marshaller.setDebug(true);
marshaller.marshal(object); // <<<<< this line changes the object
writer.flush();
marshaller = null;
document = convert(writer.toString());
}
catch (Exception e)
{
Logger.throwing(e);
throw new AppException("Unable to create XML: " + e.getMessage(), e);
}
finally
{
try
{
writer.close();
}
catch (IOException e)
{
Logger.throwing(e);
throw new AppException("Error closing the output stream");
}
}
The line of code that changes the values of the attributes of the object is
marshaller.marshal(object);
Please let me know if this is sufficient to resolve the issue.
Thanks

Have you tried to simply create a new Marshaller before marshalling?
