File I/O

Hi,
I'm reading and writing to the same file in one class. It seems that the file input stream is not closed before i open the file output stream even though I do these things at different times in different methods in my code and always 'finally' close the streams after use.
Reading:

Writing:

How do I make sure these things happen one after the other instead of at the same time?
Thanks,
Brendan

What are the symptoms you're getting?
Have you tried explictly flushing the first stream before closing it?
You got threads somewhere in there?

Getting someone to think and try something out is much more useful than just telling them the answer.

Thanks for the reply
The exception is as follows:-
java.io.FileNotFoundException: keno.xml (Permission denied)
I can write to a second file in the second part with no problems.
I get an error on compilation if I try to flush a fileinputstream and flushing the outputstream doesn't seem to do anything.
It's possible the marshal/unmarshal method is threaded.. I'll have to research it.
