Java certificate signer with A1 and A3

We need a J2EE application to sign documents with certificates in format A3(USB card reader), A1 with PFX file upload and A1 with browser certificate detection. 1) Create a simple screen with a single input for file upload. 2) User can choose 3 options: "Sign with A3 certificate" or "Sign with A1 certificate from browser" or "Upload A1 certificate" 3) In case of A1 certificate user can type the password too to send to server. 4) The server side must receive the file uploaded and the format of sign. 5) The server must sign the file with 3 different ways: 5.1) Generate a p7S/p7b file with signer information and original file content 5.2) In case of PDF files sign the file in order to show signer information inside pdf 5.3) Save the original file and the signer information into another file 6) You can create a single boolean in the servlet to configure one of the three ways above. The first person who creates a simple example and send us it working, even withour source code, you'll earn the project. Requirements: a) It must be only in Java b) It must run in apache tomcat 6 c) It must work with A3 and A1 (pfx and certified from browser) d) You must delivery the whole source code e) It cannot depend of online services in the internet f) It cannot depend on commercial third libraries - you can work only with opensource common libraries.
