You need to use the same API to extract the text fields as you've used to get the file content. Assuming that you're using the (de facto standard) Apache Commons FileUpload for this, then you need to act on whenever FileItem#isFormField() returns true.

try {
    List<FileItem> items = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : items) {
        if (item.isFormField()) {
            // Process regular form field (input type="text|radio|checkbox|etc", select, etc).
            String fieldname = item.getFieldName();
            String fieldvalue = item.getString();
            // ... (do your job here)
        } else {
            // Process form file field (input type="file").
            String fieldname = item.getFieldName();
            String filename = FilenameUtils.getName(item.getName());
            InputStream filecontent = item.getInputStream();
            // ... (do your job here)
        }
    }
} catch (FileUploadException e) {
    throw new ServletException("Cannot parse multipart request.", e);
}
