Uploading & Downloading Files into DMS Server using Web Dynpro Java

[TusharShinde]

Hello Friends,

I want to Upload a file from Portal to Document Management Server and to Download a file from Document Management Server to Portal, In short, I want to give the user the facility to Upload a File into DMS Sever via Portal and also to download the file from DMS Sever via Portal.

Can anybody give me a Input for the same from Both Java Development End as well as ABAP End, more inputs are required from ABAP end, since i have a very less ABAP Experience on working with DMS. Few Questions i have in my mind?

1. How to actually access the file contents with the help of Document Number?

2. With the help of Doc-Number we can extract the file from DMS sever but to provide a option for downloading in portal, the RFC should convert the File Contents into X-String or is there some other way?

+3. While Uploading the Data should be given in Which format to RFC? Are there any limitation with respect to size or formats. Is there any Standard RFC i can use directly in WD4 Java application to upload the file into DMS Server and which will return me the Document Number? +

Please give me your valuable inputs.

Thank You.

Now, I am able to download the File in Portal via my WD4 Java Application from DMS Server by passing the Document Number, but I am facing the problem in downloading the PDF files, Its not working for PDF files. Please give me inputs for the same.

Thank You.

The above is the RFC Code, I am using in my WD4Java app for downloading the file From DMS Server, Is there any Improvement suggested for above RFC to make it work in more efficient way. Please give me input for my Upload RFC.

Thank You.
