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 ...");

    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:

    if there are any resoures, or any other silution may help me
    please tell me about it

    I've found two loaders to load 3ds files, so if you export your models from 3ds max that should work.

  • How to connect Java Application with database!

    Dear all, now I am create a dababase application. My database use JData Store. But I don't know how to connect application with it. Can you tell me this proplem?
    Thank!

    Do a google search for JDBC, or go buy a book.
    You will need a JDBC driver which supports your database. Or you might be able to use the JDBC-ODBC bridge if there's an ODBC driver for your database.

  • Problem in connecting JSP with Oracle 9i.

    Hi,
    I am having problem in connecting JSP with Oracle 9i.
    I am using windows XP and my JDK version is 1.4. For executing JSP I am using
    "jakarta-tomcat-5.5.4-preconfigured". My database name is global.
    I have set java_home, j2ee_home, oracle_home, path, classpath as follows:
    j2ee_home=c:\sun\appserver
    java_home=c:\sun\appserver\jdk
    oracle_home=C:\oracle\ora92

    My code is as follows:
    <%@ page language="java" %>

    Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:global","scott","tiger");
