JCA Issue with migration from EP 6.0 SP2 to SAP NW2004s (EP 7.00 SP7)

Question

We are currently using JCA on EP 6.0 SP2 platform to connect to SAP R/3 backend system for custom java iviews as shown below ...
Context ctx = null;
IConnectionFactory connectionFactory = null;
IConnection client = null;
IConnection aConnection = null;
try
     //Obtain the initial JNDI context
     ctx = new InitialContext();
     //Perform JNDI lookup to obtain connection factory
     connectionFactory = (IConnectionFactory) ctx.lookup("EISConnections/SAPFactory");
     connectionFactory.setConnectionTimeOut( 900 );          
     IConnectionSpec spec = connectionFactory.getConnectionSpec();
     // FOR MiniP     
     ((Map) spec).put("client", "100");
     ((Map) spec).put("UserName", "USER_ID");
     ((Map) spec).put("Password", "password");
     ((Map) spec).put("logonmethod", "UIDPW");
     ((Map) spec).put("Language", "EN");
     ((Map) spec).put("ashost", "10.14.17.44");
     ((Map) spec).put("sysnr", "02");                              
     aConnection = connectionFactory.getConnectionEx(spec);
catch (Throwable th)
     StringWriter sw = new StringWriter();
     th.printStackTrace( new PrintWriter( sw ) );
     log("Caught an exception (Throwable) : \n" + sw.toString() );                 
When we migrated the code, the connection to SAP R/3 system is failing. Searching servicemarketplace for some solution, we found a note 820857 and made the necessary code change for JNDI lookup from "EISConnections/SAPFactory" to "deployedAdapters/SAPFactory/shareable/SAPFactory" but we are still getting the following connection failure errors ...
(R3/BW) Failed to get connection. Please contact your admin.
com.sapportals.connector.connection.ConnectionFailedException: Connection Failed: Nested Exception. Failed to get connection. Please contact your admin.
     at com.sapportals.connectors.SAPCFConnector.SAPConnectorException.getNewConnectionFailedException(SAPConnectorException.java:107)
Also, the help link is not updated for any changes ...

I really appreciate any help being provided for solving the issue.
