The Apache Commons FileUpload API is able to do that.

can you see, this code is having both file upload and jdbc script. but there is some mistake. when used in differnet file like fileupload.jsp and processform.jsp the code is working fine. when i club is not working. please help me
Why aren't you just using the FileUpload API?
Also rather use servlets instead of scriptlets.
can you please help me with the code as i am beginner and dont know where to start ..
I'll repeat myself:

So:
1) Open http://www.google.com
2) Enter "apache commons fileupload api" in that input field.
3) Hit that button next to the field.
4) Explore the results, one of the first hits should point to http://jakarta.apache.org/commons/fileupload/
5) There is a link called User Guide here which points to http://jakarta.apache.org/commons/fileupload/using.html
That ought to be sufficient. You've written a heap of code here above which parses a simple multipart request, I may assume that you know at least how it works. Or is it just copypasted code and haven't you interpreted how it works?
both the file upload and data storing scripts were written by me. but when i combine them into one peice so that file upload will work along with form data upload. can you check the code and make any modifications please
