Answer 1

As a cleaner alternative to creating an extra anonymous inner class and adding side effects to protected methods, use FormBodyPartBuilder:

StringBody stuff = new StringBody("stuff");

StringBuilder buffer = new StringBuilder();
    buffer.append("form-data; name=\"");
    buffer.append(getName());
    buffer.append("\"");
    buffer.append("; filename=\"-\"");
String contentDisposition = buffer.toString();

FormBodyPartBuilder partBuilder = FormBodyPartBuilder.create("file", stuff);
partBuilder.setField(MIME.CONTENT_DISPOSITION, contentDisposition);

FormBodyPart fbp = partBuilder.build();

Answer 2

Try this

StringBody stuff = new StringBody("stuff");
FormBodyPart customBodyPart = new FormBodyPart("file", stuff) {

    @Override
    protected void generateContentDisp(final ContentBody body) {
        StringBuilder buffer = new StringBuilder();
        buffer.append("form-data; name=\"");
        buffer.append(getName());
        buffer.append("\"");
        buffer.append("; filename=\"-\"");
        addField(MIME.CONTENT_DISPOSITION, buffer.toString());
    }

};
MultipartEntity entity = new MultipartEntity();
entity.addPart(customBodyPart);
