the class POIXMLDocument method write.

/**
     * Write out this document to an Outputstream.

     * Note - if the Document was opened from a {@link File} rather
     *  than an {@link InputStream}, you <b>must</b> write out to
     *  a different file, overwriting via an OutputStream isn't possible.
     *  
     * If {@code stream} is a {@link java.io.FileOutputStream} on a networked drive
     * or has a high cost/latency associated with each written byte,
     * consider wrapping the OutputStream in a {@link java.io.BufferedOutputStream}
     * to improve write performance.
     * 
     * @param stream - the java OutputStream you wish to write the file to
     *
     * @exception IOException if anything can't be written.
