Oh, boy, so if you have 1 GB of a file, you want to store it ALL in memory?
If you want to put your file in a temp directory, read it in chunks
(e.g. 1kB at a time) and write it in chunks.
You can also use Commons IO, in particular IOUtils.copy:
http://jakarta.apache.org/commons/io/api-release/org/apache/commons/io/IOUtils.html#copy(java.io.InputStream,%20java.io.OutputStream)
