Hello folks,
Recently, I had another problem connecting to an Oracle 10g R2 database with the Oracle Call Interface. Well, this was not about the driver actually. Having passed 2 weeks from my first problem, this time I was deploying the servlet, Tomcat 6 and Oracle 10g R2 to a OpenSUSE 10.3 machine. It still was stopping at this line:
connection = DriverManager.getConnection(url, username, password);
