Hi Hara,

Hope you have created two attributes

att1.type string for file name

att2.binary for the data stream

In init create an instance of this code

IPrivate<view name>.I<nodename>element elementname = wdcontext.create<nodename>element

Then bind it to the node

Create a simple trype using the following code

IWDAttributeInfo attinfo = wdContext.node<node name>().getNodeInfo().getAttribute("att2");

ISimpleTypeModifiable modinfo = attinfo.getModifiableSimpleType(); IWDModifiableBinaryType bintype = (IWDModifiableBinaryType)modinfo;

String location = "";

String file = wdContext.currentcontextelement.get<att1>;

String filename = location+file

File destinationFile = new file(filename);

fileOutputStream out = new fileOutputStream(destinationFile);

Check whether att2 is null or not

If not

out.write(<node element>.getatt2)

This error may be because you are not properly writing to the file

N.B.:- Settings needed to be made in server for uploading a file.

In VisualAdmin&#61664;Services&#61664;Web Container, set the parameter MultipartBodyParameterName to com.sap.servlet.multipart.body

Hope this helps you

Regards

Rohit
