Hi surya,
You can follow this procedure to upload the file
i) Take One Context Attribute named as "D1" of Type "binary".
ii) Take one FileUpload UI Element in the Layout Tab.
iii) Bind FileUpload UI Element's data Property to the taken Context Attribute. Here it is "D1".
iv) Take one Button UI Element in the Layout Tab named "Upload" and in the Action of that Button write the following Code.
v) The following code Generates one Folder in the Server & inside that Folder given file is Uploaded.
File ff=new File("FolderXYZ"); // Creates One Folder with the given Name ( Here Folder name is "FolderXYZ")
ff.mkdir();
try
byte b[]=null;
IWDAttributeInfo objAttinfo=null;
IWDModifiableBinaryType binType=null;
File f=null;
FileOutputStream fos=null;
if(wdContext.currentContextElement().getD1()!=null)
b=wdContext.currentContextElement().getD1();
objAttinfo=wdContext.getNodeInfo().getAttribute(IPrivateAttachView.IContextElement.D1);
binType=(IWDModifiableBinaryType)objAttinfo.getModifiableSimpleType();
f=new File(ff.getName()+"
"+binType.getFileName());
fos=new FileOutputStream(f);
fos.write(b);
fos.flush();
fos.close();
objMessageManager.reportSuccess("File uploaded to server");
} catch (Exception e)
objMessageManager.reportException("Unable to upload file to server, error is:"+e,false);
return;
The Uploaded file is stored in the folder & that folder is stored in the Server's following Path.
<Your Server>\c$\usr\sap\J2E\JC00\j2ee\cluster\server0
You can access your Uploaded file from the following Path
<Your Server>\c$\usr\sap\J2E\JC00\j2ee\cluster\server0\FolderXYZ
