URL string format for connecting to Oracle database with JDBC

Question

I m a newbie to Java-related web development  and I can t seem to get a simple program with JDBC working  I m using off-the-shelf Oracle 10g XE and the Eclipse EE IDE  From the books and web pages I ve checked so far  I ve narrowed the problem down to either an incorrectly written database URL or a missing JAR file  I m getting the following error      java sql SQLException  No suitable driver found for jdbc oracle   127 0 0 1 8080   with the following code   import java sql     public class DatabaseTestOne       public static void main String   args            String url    jdbc oracle   127 0 0 1 8080           String username    HR           String password    samplepass            String sql    SELECT EMPLOYEE ID FROM EMPLOYEES WHERE LAST NAME  King            Connection connection          try               connection   DriverManager getConnection url  username  password               Statement statement   connection createStatement                System out println statement execute sql                connection close              catch  SQLException e                System err println e                       What is the proper format for a database URL  anyways   They re mentioned a lot but I haven t been able to find a description   EDIT  the resolution    Based on duffymo s answer  I got ojdbc14 jar from Oracle s download site and dropped it in the Eclipse project s Referenced Libraries  Then I changed the start of the code to         jdbc oracle thin   lt hostname gt   lt port gt   lt sid gt  String url    jdbc oracle thin  GalacticAC 1521 xe         and it worked

The correct format for url can be one of the following formats:

jdbc:oracle:thin:@<hostName>:<portNumber>:<sid>;  (if you have sid)
jdbc:oracle:thin:@//<hostName>:<portNumber>/serviceName; (if you have oracle service name)

And don't put any space there. Try to use 1521 as port number. sid (database name) must be the same as the one which is in environment variables (if you are using windows).

if you are using oracle 10g expree Edition then  1  for loading class use    DriverManager registerDriver  new oracle jdbc OracleDriver     2  for connecting to database use    Connection conn   DriverManager getConnection  jdbc oracle thin username password localhost 1521 xe

There are two ways to set this up  If you have an SID  use this  older  format   jdbc oracle thin   HOST   PORT  SID   If you have an Oracle service name  use this  newer  format   jdbc oracle thin     HOST   PORT  SERVICE   Source  this OraFAQ page  The call to getConnection   is correct   Also  as duffymo said  make sure the actual driver code is present by including ojdbc6 jar in the classpath  where the number corresponds to the Java version you re using

Look here   Your URL is quite incorrect   Should look like this   url  jdbc oracle thin  localhost 1521 orcl    You don t register a driver class  either   You want to download the thin driver JAR  put it in your CLASSPATH  and make your code look more like this   UPDATE  The  14  in  ojdbc14 jar  stands for JDK 1 4   You should match your driver version with the JDK you re running   I m betting that means JDK 5 or 6

I m not a Java developer so unfortunatly I can t comment on your code directly however I found this in an Oracle FAQ regarding the form of a connection string  jdbc oracle  lt drivertype gt   lt username password gt   lt database gt    From the Oracle JDBC FAQ  http   www oracle com technetwork database enterprise-edition jdbc-faq-090281 html 05 03  Hope that helps
