Different weblogic JNDI Connections sharing the same dbms session

Question

Hi,
we have setup JDBC Datasource on the weblogic server. Creating connection using JNDI lookup is sharing the same session across different connections, which is causing invalid data generation in global temp tables. The data in the global temp table is accessed accross db sessions.
I have created a test case, using JDBC connection, the global temp table data is not accessible across session (this is correct behavior).
where as using JNDI connection the data from the temp table is accessed across different connections. (This is not expected behavior)
I tried setting statement cache = 0, Remove Infected Connections Enabled = true / false but no use.
is there any other setup in the weblogic to avoid db session sharing across connections??
Thank you,
Ranga

I am using a single thread, This can be easily reproducible on any machines.
@ Sequence to follow
@ public static void main(String[] args) {
@ for (int i =0; i < 3; i++)
@ try{
@ conn = getJNDIConnection();
@ printSessionDetials();
@ insertValuesToTempTable();
@ QueryRecordsFromTempTable();
@ }finally
@ conn.close();
@ Test Results:
@ JNDI connection found: jdbc/xdo120DBDS
@ V$Session Details....
@ SessionId:299:serial#:909:Seq#:31:dbmsSessionId:012B038D0001
@ Number of Records:1
@ connection is closed.....
