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

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 ...");

the error message is

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.

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
path=C:\Sun\AppServer\bin;C:\Sun\AppServer\jdk\bin;C:\oracle\ora92\bin
classpath=C:\Sun\AppServer\lib\j2ee.jar;C:\oracle\ora92\jdbc\lib\ojdbc14.jar;C:\oracle\ora92\jdbc\lib\nls_charse
t12.zip
My code is as follows:
<%@ page language="java" %>
<%@ page import ="java.sql.*"%>
<%
try
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
Connection conn = DriverManager.getConnection ("jdbc:oracle:oci8:@global", "scott", "tiger");
catch(SQLException e)
out.println(""+e);
out.println("Connected");
%>
I tried other program:
<%@ page language="java" %>
<%@ page import ="java.sql.*"%>
<%
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:global","scott","tiger");
out.println("Connected");
%>
I am getting following error:

Hi,
Go to technical landscapes and create a technical landscape for your ECC backend system.

Connect JAVA with ABAP

Hi,
I have a requirement in my project to connect Java with ABAP. I want to access ABAP tables from my java application. I am not sure but I think we can use SAP JDBC drivers to do that.
I found this link to connect JAVA with ABAP :
SAP DB JDBC Driver
My doubt from this link is where can I get the Host Name for the sandbox system I am using and what is the Database Schema name for the tables created using se11.
Regards,
Prateek

Hi
If you have direct connection to data base then you can use
the JDBC driver for the data base that is in use (We have oracle).
But usually you have to go through the application server this mean you have to use "SAP Java Connector" that connect to SAP using RFC .
Talk to your basis people.
Regards.

Can' t connect Java with MySQL

My goal is to connect Java with MySQL. I found many solutions on Internet, but I always get the same mistake:
SQLException: No suitable driver
SQLState: 08001
VendorError: 0MySQL works fine alone or with php.Only thing left me to think is that the installed versions are not compatible for this mysql-connector-java-5.0.4
I don't believe that could be a reason.
Installed versions are:
Apache Tomcat 5.5.20 Server
Apache HTTP Server 2.2.4
PHP 5.2.0
MySQL 5.2
jre 1.5.0_11
jdk1.5.0_11
Apache Tomacat JK2 connector Version: 1.2.20 File Name: mod_jk-apache-2.2.3.so
mysql-connector-java-5.0.4
I also set connector in class path: C:\mysql-connector-java-5.0.4;C:\mysql-connector-java-5.0.4\mysql-connector-java-5.0.4-bin.jar;C:\mysql-connector-java-5.0.4\src\com\mysql\jdbc
For installation I used manulas from:
http://apacheguide.org/jsp.php
http://doc.51windows.net/mysql/?url=/MySQL/ch23s03.html
Here is also a test code in java:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
   public class Connect
       public static void main (String[] args)
           Connection conn = null;
           try {
    conn =
       DriverManager.getConnection("jdbc:mysql://localhost/first_test" +
                                   "user=monty&password=greatsqldb");
    // Do something with the Connection
} catch (SQLException ex) {
    // handle any errors
    System.out.println("SQLException: " + ex.getMessage());
    System.out.println("SQLState: " + ex.getSQLState());
    System.out.println("VendorError: " + ex.getErrorCode());
   }i'm desperate, please help or tell me someone who'll know the answer.
Thank You in advance

hey buddy .. it seems yr code is wrong .. in getconnection () method u should also specify the port ,which u r not doing ...
the default port for MySQL is 3306 ... see below i am giving you a sample code ... its working fine .. and dont forget to put the MySQL driver jar path in to classpath and also copy the jar into common/lib folder of your tomcat ....
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class MySQLConnectionTest {
     public static void main(String[] args) {
new MySQLConnectionTest().connTest();
public void connTest() {
          String tableName = "portfolio"; //change as per setting
          String hostName = "10.81.9.39"; // please change for the target database ip or hostname
          String dbPort = "3306"; //change if not using the default
          String dbName = "tradingsystem"; //change as per the given DB name
          String username = "root"; //change as per setting
          String password = "password"; //change as per setting
          System.out.println("before try");
          Double data=0.0;
     Double data1=0.0;
          try {
Class.forName("org.gjt.mm.mysql.Driver");
               System.out.println("before driver manager");
Connection conn = DriverManager.getConnection("jdbc:mysql://"+hostName+":"+dbPort+"/"+dbName, username, password);
String query1 = "select * from "+tableName+" where User_id='trader1' and Stock_Type='Equity'";
System.out.println("quesry1="+query1);
Statement stmt = conn.createStatement();
ResultSet rs1 = stmt.executeQuery(query1);
while(rs1.next())
     System.out.println("hiiiiii for rs1");
     System.out.println(rs1);
     Quantity=(Integer)rs1.getObject(5);
     MarketPrice=(Double) rs1.getObject(8);
     data=Quantity*MarketPrice;
     data1+=data;
     System.out.println("data1="+data1);
     i=0;
rs1.close();
stmt.close();
conn.close();
} catch (ClassNotFoundException e) {
e.printStackTrace(System.err);
} catch (SQLException e) {
e.printStackTrace(System.err);
i hope it will work for u...

Unable to connect forms6i with oracle 10g

hi:
i am facing a problem to connect forms6i with oracle 10.2 g. i already make a entry in TNSNAMES.ora file in forms folder.
while i am trying to connect it dispaly "ORA-12203: TNS:unable to conect to destination" error.
please help. Thanks in advance.
Regards,
Abhishek

Hi
i already make a entry in TNSNAMES.ora Another option...
1. Pls Verify that the net service name you entered was correct including no spaces.
2.Verify that the ADDRESS portion of the connect descriptor which corresponds to the net service name is correct.
3.Ensure that the destination process (for example the listener) is running at the remote node and the cabel of ur local net work connecting to ur server is well connected and working well.
4. Test ur local network cabel and try to make the connection to another computer set.
5.u can check from Start > control panel > administrative tools > services that the service name is started or not if it is Started Restarted or refresh it.
6. Ensure that the listener is running at the remote node and that the ADDRESS parameters specified in TNSNAMES.ORA are correct.
and the more ....
Hope this helps...

Abdetu...
