Dmk,

Can you post the file or the code please

Andrew,

I figured it out. But thanks for the reply.

Andrew Sorry for wrong reply last time. Its still not working. I am attaching My code file.

Dmk,

It's going to be hard to give you a solution but I can give you some more information about what's supposed to happen and perhaps you can figure out what's different in your environment.

At the bottom I've pasted a sample XML response that the GetNamespaces method is parsing.  This is what it's supposed to look like, I believe yours is different.

You're failing on this line:

Code Select Expand

if (dob[i+1].getName().equalsIgnoreCase(("CAMNamespaceDisplayName")))

dob is the node for the CAMNamespace.  We know that it is there because we passed a check on line 506.
dob[i+1] is supposed to be the CAMNamespaceDisplayName node (example below) which can be expected if the first node is CAMNamespace.  I believe that this is missing, in fact you only have the CAMNamespace node, nothing else.  Hence the Index error when you try to index [i+1].

The next thing to look at is your configuration.  How many namespaces do you have set up and what are they?


There is another thing you can do which is a workaround, not a solution.

Replace this code:

Code Select Expand

if (dob[i+1].getName().equalsIgnoreCase(("CAMNamespaceDisplayName")))
{
   namespaces = new String[2];
   namespaces[0] = dob[i+1].getValue();
   namespaces[1] = dob[i].getValue();
}else
{
   namespaces = null;
  }

With this:

Code Select Expand

   namespaces = new String[2];
   namespaces[0] = dob[i].getValue();
   namespaces[1] = dob[i].getValue();

This will show the Namespace ID as the ID and Display Name.  Perhaps this can also help you uncover the real issue.

Andrew,

I have 2 NameSpaces configured, one is cognos (Which comes default with BI) and another which is mentioned in my java code (Its a Custom Java Provider)

[Andrew Weiss]

Ah hah! That there's your problem.  The Customer Authentication Provider provides the prompt information to the Logon Screen.  The sample logon scripts that IBM ships assume that you're following the standard that there's a namespace id, namespace name, username and password.  With a customer provider it's up to you to provide this information or something different.  You'll need to modify the script to match what the custom authentication provider actually uses to authenticate (which may not be a username and password).  At this point you're working on something custom so I'm not sure that there's much more I can provide. However if you want to consider using our MetaManager API as opposed to the Cognos SDK I think yo will find more success with working with Custom Authentication Providers.  We have full support custom authentication providers.   You can find some more information and example MetaManager API Scripts here: http://www.bspsoftware.com/products/metamanager/api/

Thank you,
-Andy
