Document management server in web dynpro abap

Requirement : Based on different project types , we had to store any type of file in SAP . So i found the concept of DMS(document management server) where we can store any type of file But my problem was when i was doing this activity from SAP GUI document number was generating and document was getting stored in DMS using BAPI BAPI_DOCUMENT_CREATE2 but from Web dynpro it was not getting updated so what i did is below :
FILE UPLOAD UI element in webdynpro takes the file from presentation server (desktop) and convert it to hexadecimal format...after that we have convert into binary format.
