File upload problem in java servlets

Question

hello,
I want to upload my files.i have used Multipartrequest object.In my form i had included enctype="multipart/form-data".
I want to upload one or more files .
So, I made a file input box and then a select option box. With the help of java script i stored the values of the file input box to the select option drop down box.In this way i stored the name and path of the file in the select option drop down box also. Now when i tried to upload all the file in the select option box it is uploading only one file which is the last one selected from the file input box.
I hope that file name is also getting from the file input box, and that is the reason why it is uploading that file only.I write this code to execute it.
MultipartRequest multi=new MultipartRequest(request,".",5*1024*1024);
I want to upload all the files, so what should i do,
Please help me to solve this problem

Hi,
First go through the Multipart code and try to study what it does.it does not upload all the fields u submit in a form.it will first parse the servletInputStream which seperates the normal form fields and the "File" field.when u say ENC-TYPE="multipart/form-data" the way in which it is sent is different for normal fields and the "File" field.there'll be boundaries for each field.also for "File" field the filename will be passed in the Content-disposition info(which contains the values of form fields,their names and filename(only for File input)in specific format) .so if u want to upload more files in the same submit use two or more "File" fields.
If any one else has a better option let me know
