Connecting JAVA to Oracle?

Hi Folks...I am an absolute newbie in JAVA....I have Windows Media Centre installed on my machine...Also I have Oracle 10g release 2 for the same....But I haven't installed it(oracle) yet....I have also not installed Java....First and foremost give me the link to download java so that I can run my java programs from Windows Command line...also this version of JAVA should be compatible with Oracle 10g release 2 for Windows.....Actually I want to connect my JAVA to ORACLE using JDBC...I have no idea what so ever on how to achieve it..So can any one please give some online link or resource to use JDBC or suggest some good book for it........

For the JDBC Drvier:
www.oracle.com and search for the newest JDBC Driver
For Java:
java.sun.com and follow the links for JSE (Java 6) and download the JDK (not just the JSE). Then follow the links to the API documentation and bookmark that, then, in that documentation, there is also a link to the Tutorials. Bookmark that, too.

How to connect java with oracle

can any body show me the code of how to connect java with oracle database.
thank you

To configure Oracle JDBC:
1. Add Oracle JDBC JAR file classes12.zip or ojdbc14.zip to classpath.
2. Load and register the JDBC driver.
Class.forName("oracle.jdbc.driver.OracleDriver");
3. Obtain a connection:
String url="jdbc:oracle:thin:@<host>:1521:<database>
Connection con = DriverManager.getConnection(url,
"myLogin", "myPassword");
4. Create a SQL statement.
Statement stmt = con.createStatement();
5. Obtain a result set.
ResultSet rs = stmt.executeQuery(
"SELECT ...");

Please Help Me
Thanks For Reading
Thanks a lot in Advance For your ANSWERS

maybe if you asked nicely instead of ordering people around we might tell you.
As it is all you're going to hear is that you don't need both those jars, as they contain different versions of the same driver.
I'm not going to tell you which you need, as you should have the documentation to tell you that. But then you also should have the documentation to tell you how to set your classpath properly and you failed to read that too.

Cant connect java with oracle

i am new to oracle.
i cant connect java(jdk1.3) to oracle using 'oracle.jdbc.driver.OracleDriver' in Class.forName() and DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl","scott","tiger")
it shows "class not found" error.
is there any one to suggest or help me?

Hi,
you are posting in wrong forum, as this one is for SQLDeveloper-related issues only. You should post java-related issues in this forum:
SQL Developer
However, about your exception you have missed to put the oracle jdbc driver in the classpath.
Download it from here:
SQL Developer
and see more info here:

Problem connecting java to oracle

new to jdbc so might appear stupid, but i have tried to create a basic connection from a java application to oracle using the following code
Class.forName("oracle.jdbc.driver.OracleDriver") ;}
system.out.println("msg1");
con = DriverManager.getConnection
("jdbc:oracle:thin:@//(local host)","(username)", "(password)");
system.out.println("msg2");
but when i run the application it displays msg1 fine, but then seems to run into a problem because it is contiuously running without carrying out the other commands, and needs to be stopped manually. problem is i done the exact same thing on another computer and works fine. Was wondering if a firewall problem or something, any help would be appreciated.

It looks like the connection URL is not complete. Need to specify the database port number and SID (1521, and XE, for example).
The examples in Oracle's JDBC FAQ page:
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@//myhost:1521/orcl", "scott", "tiger");
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:scott/tiger@myhost:1521:orcl);

You "don't get things", that is a problem you have to solve before you can be helped. Maybe you just need to spend more time on it or find better documentation; API documentation is only a reference, not a manual.

I am pretty sure , i am using proper credentials since am able to java cloud service console with same credentials.
Please help me out on this.
Thanks

Hi Thanks for the reply
I check check-box of proxy settings and restarted the jdeveloper and tried again but still it throws the same error? one doubt here...what all we need to include / exclude in our proxy settings...
and the I tried providing service name as both java and javatrial8477 but no luck i followed the same steps which are mentioned in the below document
Part 2: Deploying ADF Applications to Oracle Java Cloud
Do i need to do any other configuration? Or i can directly deploy my ear file to java service console rt instead of creating connection tot the server from IDE.

Can anyone send me the sample code to connect to a database
<b>very urgent</b>
Thanks in advance

Hi Sushma
Ask your system Admin for servername,portnumber of database server
Connection conn=null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn =DriverManager.getConnection ("jdbc:oracle:thin:@<servername>:<portnumber>:DB","uname", "pwd");
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("select * from <tablename>"); // select statment
while(rs.next())
IXXElement nodeConnection=wdContext.createXXElement(); //creating a node to store the data from oracle
nodeConnection.setYY(rs.getInt("YY")); // setting the values into input fields
nodeConnection.setAA(rs.getInt("AA"));
nodeConnection.setBB(rs.getInt("BB"));
wdContext.nodeXX().addElement(nodeConnection); // adding the node
catch(Exception ex)
finally
try
conn.close(); // closing the connection

WebDynpro java and Oracle Connection

Hi,
I'm trying to make a simple connection to an Oracle database within a custom webdynpro component. Using NWDS 7.0.08 and EP 7.0 SP 10.
Here is a sample of the java code I use :
Connection conn = null;
Class.forName("oracle.jdbc.driver.OracleDriver");
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn =DriverManager.getConnection ("jdbc:oracle:thin:@hostname:port:DATABASENAME","schema", "password");
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("select * from MYTABLE");
But when I run this WebDynpro, the following error appears :
"oracle.jdbc.driver.OracleDriver".
I have also catched the exception stack but it doesn't seem meaningful. If you need it, I can provide it in another thread.
So What should I do to connect to this oracle database ? Is it the right provider ?
Thanks,
Loïc LEVEUGLE

Hi!,
please try following code, this is working fine for me.
String serverName = "172.21.1.62";
String portNumber = "1526";
String sid = "vision";
String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;
String userName = "scott";
String password = "tiger";
Connection connection = null;
try {
    // Load the JDBC driver
    String driverName = "oracle.jdbc.driver.OracleDriver";
    Class.forName(driverName);
    connection = DriverManager.getConnection(url, userName, password);
    Statement stmt =connection.createStatement();
    PreparedStatement pstmt = connection.prepareStatement("insert into club (Name,EmpID,Location,Extention,MailID,InstPlay) values(?,?,?,?,?,?)");
               pstmt.clearParameters();
    pstmt.setString(1,Name);
    pstmt.setString(2,EmpID);
    pstmt.setString(3,Location);
    pstmt.setString(4,Extention);
    pstmt.setString(5,MailID);
    pstmt.setString(6,Instrument);
    pstmt.executeUpdate();
} catch(Exception exc) {
     exc.printStackTrace();
put classes12.jar in your class Path.

Webdynpro java and oracle DB connection..

Hi,
I have a good knowledge of WD (web dynpro java) projects having ECC as backend as i have done lot of projects where ECC is backend and WD JAVA is front end.
but in my new project i have wd java as front end but my backend is oracle DB. I want to know how to create/setup connection betwen webdynpro java and oracle DB, how to proceed on this ? wat all settings I have to do in VA (visual admin) and all.
please let me know how to proceed on this. Any document/tutorial on this will be very helpful..

Hi Rahul,
Create a DataSource to the oracle db in Visual Admin, give the datasource an alias name and connect to the db from WebDynpro by calling the alias name.
These document might be useful:
