Trying to connect to Sybase with Java jdbc

Question

Hoping someone can help me to connect to Sybase database (version is Sybase Adaptive Server Enterprise 12.5.3). I am using a technique I read that worked with Access and adapting by some examples for Syabase I found on the web but keep getting errors. Below is my code with some of the examples Ive been using commented out.
I have created a DSN on my Windows Xp o/s named GPTS_SYBASE via ODBC Use DSN set-up wizard, driver is Sybase ASE ODBC Driver.
import java.sql.*;
public class DBConn {
public DBConn(){
public static void main(String[] args) {
try {
//Class.forName("com.sybase.jdbc2.jdbc.SybDriver.class.getname()");
//Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Class.forName("com.sybase.jdbc2.jdbc.SybDriver");
String sourceURL = "jdbc.odbc.GPTS_SYBASE";
//String sourceURL = "jdbc.sybase.Tds:GPTSPSYB1:5000/gpts";
Connection conn = DriverManager.getConnection(sourceURL, "gptsdbo", "gptsdbo");
//Connection conn = DriverManager.getConnection(sourceURL);
System.out.println("Success");
} catch (Exception e) {
System.err.println("Got an excpetion! ");
System.err.println(e.getMessage());
Error message from this code is
Got an excpetion!
com.sybase.jdbc2.jdbc.SybDriver

Have you read the Sybase docs or the Java JDBC docs? ODBC != JDBC. They sound the same but are totally different. The DSN is totally irrelevant for type 4 JDBC drivers.
It would help to actually print the stack trace by changing your code to:
catch (Exception e) {
    System.err.println("Got an excpetion! ");
    e.printStackTrace();
}Also, you're mixing the wrong class name with the URL. You need "com.sybase.jdbc2.jdbc.SybDriver" and, in your case jdbc:sybase:Tds:GPTSPSYB1:5000/gpts - note the change to colons, not periods! - when in doubt read the docs!
