Hi Anil,
1) Create a Web Dynpro appliaction.
2) In the view, create a file upload UI element
3) In the context of the view create a context element of type "binary"
4) In the doInit() method create a modifiablesimpletype for that context element.
wdContext.getNodeInfo().getAttribute("<contextelementname>").getModifiableSimpleType();
5) Now, bind the context element of type binary to the UI element.
6) Now create a button UI element on the action of which we shall fire an event of uploading the file.
7) In the event method for the button,
- Create a File object using
File f1 = new File("<path of the file to be stored on server>");
- Create a fileoutputstream object to be associated with the above created file object
FileOutputStream fop = new File OutputStream(f1);
- Now the context element created previously contains the uploaded file in binary format. Convert this to outputstream format
- And assign this to the fileoutputstream object
- Flush and close the fileoutputstream and file objects.
8) Deploy and run this web dynpro application
