FileUpload java.lang.OutOfMemoryError: Java heap space

[morellik]

Dear,

uploading a big file (900MB) using rich:fileUpload give me java.lang.OutOfMemoryError: Java heap space. There is a way to solve the problem?

  <rich:fileUpload fileUploadListener="#{fileUploadBean.listener}"  
                                             id="upload" acceptedTypes="txt,csv,pdf,iso,tar,zip,tgz,gz"  
                                             ontyperejected="alert('Only Text and CSV files are accepted');"
                                             doneLabel="#{fileUploadBean.uploadDoneLabel}"
                                             maxFilesQuantity="5">  
                                <a4j:ajax event="uploadcomplete" execute="@none" render="info" />  
                            </rich:fileUpload>  

 public void listener(FileUploadEvent event) throws Exception {
        ufile = new UploadFile();
        UploadedFile item = event.getUploadedFile();
        UploadedText file = new UploadedText();
        file.setLength(item.getData().length);
        file.setName(item.getName());
        Date date = new Date();
        String epoch = fDir + String.valueOf(date.getTime());
        File fPath = new File(epoch);
        fPath.mkdir();

        //file.setData(item.getData());
        files.add(file);
        String filename = epoch + '/' + item.getName();
        FileOutputStream fop = null;
        File fout;
        if (file.getLength() > 0) {
            try {
                fout = new File(filename);
                fop = new FileOutputStream(fout);

                if (!fout.exists()) {
                    fout.createNewFile();
                }
                fop.write(item.getData());
                fop.flush();
                fop.close();

Thanks

I increased the heap space in Glassfish to 2048 but I've the same problem.
