Otherwise you can simply follow this code for file download
Use the code like this.
1) Create the button and bind the action for it.
2)then write this code in the action.
3) do not write any thing in the init method.
try {
final byte[] content = this.getByteArrayFromResourcePath("C:
xyz.properties");
final IWDCachedWebResource resource = WDWebResource.getWebResource(content, WDWebResourceType.UNKNOWN);
try {
final IWDWindow window = wdComponentAPI.getWindowManager().createExternalWindow(resource.getAbsoluteURL(), "WD_Filedownload", false);
window.open();
catch(Exception e)
wdComponentAPI.getMessageManager().reportException(new WDNonFatalException(e), false);
5) writr the method getByteArrayFromResourcePath
//@@begin others
private byte[] getByteArrayFromResourcePath(String resourcePath)
throws FileNotFoundException, IOException {
FileInputStream in = new FileInputStream(new File(resourcePath));
ByteArrayOutputStream out = new ByteArrayOutputStream();
int len;
byte[] part = new byte[10 * 1024];
while ((len = in.read(part)) != -1) {
out.write(part, 0, len);
in.close();
return out.toByteArray();
//end
Similarly for file upload
Similarly for upload in to server path also do the same
IWDAttributeInfo attInfo =
wdContext.getNodeInfo().getAttribute("upload");
binaryType =
(IWDModifiableBinaryType) attInfo.getModifiableSimpleType();
uploadedName = binaryType.getFileName();
File filename =new File("
<server name>
<folder name>
"+uploadedName ); );
try {
FileOutputStream out = new FileOutputStream(filename);
out.write(b);
out.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
