DataSource problem in Jdev10.1.3.4

Question

I am running OC4J in Jdeveloper 10.1.3.4 and setup a DataSource to connect to the DB on remote machine.
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/name");
if I am trying to get connection this way :
Connection con = ds.getConnection();
I am getting "java.sql.SQLException: User credentials doesn't match the existing ones" exception , though I am 100% sure username/password are correct.
If I am trying to get connection like :
Connection con = ds.getConnection("username","password");
then : "java.sql.SQLException: Io exception: The Network Adapter could not establish the connection"
any ideas?

Answer 1

I had a problem with URL and after I fixed it I was able to connect using :
Connection con = ds.getConnection("username","password");
however while trying to connect using :
Connection con = ds.getConnection();
still gives me an exception "java.sql.SQLException: User credentials doesn't match the existing ones"
