when i am trying to connect to project while giving
host name ********
user name ********
password *********

and trying to select the project, the following error occurs.

javax.security.auth.login.LoginException: A communication failure occurred while attempting to obtain an initial context
with the provider URL: "iiop://tds:2809".

Make sure that any bootstrap address information in the URL is correct and
that the target name server is running.

A bootstrap address with no port specification defaults to port 2809.
Possible causes other than an incorrect bootstrap address or unavailable name server include the network environment and
workstation network configuration.

Note: I am using DATASTAGE VERSION 8.0.1

ANY ONE PLEASE TELL ME HOW TO RESOLVE FROM THIS ONE

You don't connect to a project any more.

You connect to IBM Information Server (machinename:9080) and authenticate there. That having been done, you will be presented with a drop-down list of DataStage server/project combinations, and can choose one from that list.

While I am clicking Drop down list only I got that error msg.

Is that related to ports for DSserver to be opened for my machine.,

If that is the case I have one port to be opened still

9080 port is opened for my machine.

All my ports for connecting to Datastage Server has been opened, still I am having the problem in attaching to the project

Failed to authenticate the current user against the selected Domail:

can you, from a DOS shell window, execute "telnet {dsserver name} 9080"? If it works you will get a response and a timeout after a minute or two, if it isn't opened then you won't get a connection.

check your hosts file
I assume you have a windows client there it is under C:\WINNT\system32\drivers\etc .
Here you need to add the IP and name of your datastage server.

I had copied HOSTS file from another system which is working and pasted.

now its working

thanks for your guidance
