T4CConnection Error while creating datasource in SOA 11g

Question

Hi All,
i getting the below error while creating the data source with an oracle database in oracle SOA 11g. I trying to create the datasource in the weblogic console page. The error is specifically coming while testing the database connection.
However, i am able to telnet the database box on this particular port..  Also this used to be a working connection earlier and i am able to create the same datasource from other similar SOA 11g instance...
the error details are:-

please let me know in case any of you know the fix..

i also used the weblogic jar to do a db ping..  and it errored out with the above error.  however if i db ping from any other app server it works...  below is the success response from another server and the command used..
[applmgr@g3te2soa lib]$ java -classpath /u01/app/Middleware/wlserver_10.3/server/lib/weblogic.jar utils.dbping ORACLE_THIN apps appsuat abc1.xyz.net:1525:oru1
**** Success!!! ****
You can connect to the database in your app using:
  java.util.Properties props = new java.util.Properties();
  props.put("user", "apps");
  props.put("password", "appsuat");
  java.sql.Driver d =
    Class.forName("oracle.jdbc.OracleDriver").newInstance();
  java.sql.Connection conn =
    Driver.connect("jdbc:oracle:thin:@abc1.xyz.net:1525:oru1", props);
is it some netwrok issue..  but why is then the telnet working for the same server on this port ????
