Code Challange - Code for extracting content from a file in KM

Question

Hi,
  I want to extract content from a file which is in KM Repository using the Webdynpro View.  I wrote the following code for the extraction. But it is throwing some exception.
Code Written:
<b>  
  URLConnection conn = null;
      DataInputStream data = null;
      String line;
      StringBuffer buf = new StringBuffer();
     wdContext.currentContextElement().setTextdisp("Hello");
     try {
      URL theURL = new URL("http://ctssap1:50000/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/News/New%20text.txt");     
        conn = theURL.openConnection();
       // conn.connect();
        wdContext.currentContextElement().setTextdisp("Inside Try");      
        data = new DataInputStream(new BufferedInputStream(
                           conn.getInputStream()));
        while ((line = data.readLine()) != null) {
           buf.append(line + "\n");
        data.close();
        String buffer = new String(buf);
        wdContext.currentContextElement().setTextdisp(buffer);
      catch (IOException e) {
          wdContext.currentContextElement().setTextdisp("IO Error:" + e.getMessage());
      }</b>
Exception Got:
<b>IO Error:Server returned HTTP response code: 401 for URL: http://ctssap1:50000/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/News/New%20text.txt</b>
Can anyone help me out in this process... or please suggest some other way to extract the content.
Thanks in Advance.

Hi Srinivas,
VaPath will have the path of ur document.
Check this modified code snippet which will answer ur  questions and solve ur problem.
IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
IUser sapUser = wdClientUser. getSAPUser();
com.sapportals.portal.security.usermanagement.IUser ep5User = WPUMFactory.getUserFactory().getEP5User(sapUser);
IResourceContext context = new ResourceContext(ep5User);
/Specify the path of ur document here./
RID pathRID = RID.getRID("/documents/file2");
IResource resource = ResourceFactory.getInstance()
.getResource(context);
InputStream in = resource.getContent().getInputStream();
ByteArrayOutputStream out = new ByteArrayOutputStream();
byte[] buffer = new byte[4096];
int bytesread = 0;
while ((bytesread = in.read(buffer)) != -1) {
out.write(buffer, 0, bytesread);
String myData = out.toString();
/*myFile will containS the content of the document./
wdComponentAPI.getMessageManager().reportSuccess(myData);
Hope this solves ur problem.
