Getting error while Creating a JDBC connection from Java Class

Question

Hi,
I am getting the exception pasted below:
Exception in thread "main" java.lang.AbstractMethodError

at java.sql.DriverManager.getConnection(java.lang.String, java.lang.String, java.lang.String) (/usr/lib/libgcj.so.5.0.0)
The code raising this error is :
try
               Class.forName("oracle.jdbc.driver.OracleDriver");
          catch (Exception Exp)
               System.out.println("Error while getting the class : "+Exp);
try
               String url = "jdbc:oracle:thin:@hostname:port:SID";
               String user = "apps";
               String password = "password";
               con = DriverManager.getConnection(url,user,password);
catch (Exception ex)
               System.err.println("SQLException: " + ex.getMessage());
Any help in this is appreciated.

Why do you have the Class.forName() in a separate try-catch block than the DriverManager.getConnection()?
Try placing everything in the same try-catch block to see if that resolves your problem.
You may also want to try using an OracleDataSource.
OracleDataSource ods = new OracleDataSource();
String url = "jdbc:oracle:thin:@//hostname:port/SID",
ods.setURL(url);
ods.setUser("apps");
ods.setPassword("password");
Connection conn = ods.getConnection();
