ZIPPING IN JAVA WITHOUT PATH STORE

Hello,

I've searched the API's but didn't see anything about the following
problem : I'm using java.util.zip to create a zip file containig some
xmls. No trouble creating the zip but when opening it, I see the files
all have the folder structure of the location(where the xmls were)
and where I made the zip file. To avoid this in winrar I normaly
chose in options the "do not store path" option. Can I do this in
java?

TIA, D

    private void zip (){

    File[] xmls = getFileArray(BASE_PREFIX, XML_EXTENTION);

        byte[] buf = new byte[1024];

        try {

            String outFilename = OUTPUTZIP;
            ZipOutputStream out = new ZipOutputStream(new
FileOutputStream(BASEDIR + SLASH + nbrTreated + outFilename));

            for (int i=0; i<xmls.length; i++) {

                String filename = BASEDIR + SLASH + xmls[i].getName();

                FileInputStream in = new FileInputStream(filename);

                out.putNextEntry(new ZipEntry(filename));

                int len;
                while ((len = in.read(buf)) > 0) {
                    out.write(buf, 0, len);
                }
                out.closeEntry();
                in.close();
            }

            out.close();
        } catch (IOException e) {
         e.printStackTrace();
        }
    }
