    SQL Developer tool giving error Network Adapter could not establish

    user8904001
      Hello,

      I installed oracle 11.2 client on my windows 7 machine.

      When i connect sql developer, i get the below error.

      status : Failure - Test failed : The network Adapter could not establish the connection

      I am using network Alias to select SID name.

      I am able to connect the same database through sqlplus. I am able to ping the tnsname. I am able to telent the server for 1521 port.

      What else could be the issue?

      Any help is appreciated.
