Problem in adding attributes to an iView

Question

I am facing some problems while working with PCD api.
My requirement is to get an existing iView and add attributes to that. I am using the below code to do this.
My problem is that
1.  I am not able to add attributes using obj.addToEnvironment("test",myAttrs);
2.  Using IPcdContext obj = (IPcdContext)myPcdContext.lookup(iView_ID); when I do a lookup, I was supposed to get an object of type IiView. But getting IPcdContext.
IUser user = null;
try {
     user = WDClientUser.getCurrentUser().getSAPUser();
} catch (WDUMException e) {}
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,IPcdContext.PCD_INITIAL_CONTEXT_FACTORY);
env.put(Context.SECURITY_PRINCIPAL, user);
env.put(Constants.REQUESTED_ASPECT, IPcdAttribute.PERSISTENCY_ASPECT);       
InitialContext   iCtx = null;          
try {
     iCtx = new InitialContext(env);
      // Get the top-level context
     IPcdContext myPcdContext = (IPcdContext) iCtx.lookup("");
     <b>IPcdContext obj = (IPcdContext)myPcdContext.lookup(iView_ID);</b>
     Attribute attr1 = new BasicAttribute("attribute_created_by_figi1","one");
     attr1.add("two");
     Attribute attr2 = new BasicAttribute("attribute_created_by_figi2","three");
     Attributes myAttrs = new BasicAttributes();
     myAttrs.put(attr1);
     myAttrs.put(attr2);
     <b>obj.addToEnvironment("test",myAttrs);     </b>           
} catch (NamingException e) {
     // TODO Auto-generated catch block
     e.printstacktrace();

Hi Figi,
It is best to use the semantic interface. So you need to:
Change the aspect in the environment variable to the semantic aspect
Get an IiView interface
Set the property there, and call the save() method to have the change take effect.
All of the procedures for this is described in:

Hope this helps.
