OracleDriver

Hi,
I have been trying to connect to an Oracle 8i database using jdbc.
Initially I could not get my class to compile with the error, oracle.jdbc.oracle.OracleDriver not found.
Then after correcting my classpath, I got my class to compile.
Now when I run it, it gives NoClassDefFoundException
A small test program will just the connection code compiles and works fine.
What then is the problem with my main program, which just has some package declarations and import statements that the test program does not have?
Thanks in advance,
Vishakha

You need to have Oracles JDBC driver available to your web application.
That means the driver (commonly called ojdbc14.jar) should be in either the WEB-INF/lib directory of your web application, or in the [TOMCAT]/lib directory.
However it is generally accepted that Database connections from JSP pages are a bad idea.
Put this logic in java code/beans.
Even better, set up a [JNDI Datasource in Tomcat|http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html] that your web application can access. That way your code can be database independant.

A sign Applet unable to load "oracle.jdbc.OracleDriver" class

hi,
i am chiranjit , i am now working in a web based ERP. where i am using a signed applet which unable to load "oracle.jdbc.OracleDriver" class but it easily loading "sun.jdbc.odbc.JdbcOdbcDriver", i am also giving my code:
import java.sql.*;
import java.math.*;
import java.io.*;
import java.awt.*;
class JdbcTest extends Applet{
public static void main (String args[]) throws SQLException {
// Load Oracle driver
DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
// Connect to the local database
Connection conn =
DriverManager.getConnection
("jdbc:oracle:thin:@192.168.16.7:1521:kris",

// Query the employee names
Statement stmt = conn.createStatement ();

Hint: The sun.jdbc.odbc.JdbcOdbcDriver is available in any JRE distribution. The Oracle driver is not.

Unable to load oracle.jdbc.driver.OracleDriver class

i want to connect my java application with oracle database but i m getting an error -"class not found exception oracle.jdbc.driver.OracleDriver " which is written in Class.forName() to register the driver for DriverManager.
plz help me..

This is an old class, not included with the JDK anymore. It was made obsolete by
DataSource which is a connection pool and not a single connection.

If this is a type-4 JDBC driver, it could occur if the JDBC
driver is not in the system CLASSPATH.
If this is a type-2 JDBC driver, it may also indicate that
the Driver native layers(DBMS client lib or driver DLL)
have not been installed properly on your system
or in your PATH environment variable.
This is most likely caused by one of the following:
1. The native layer SO, SL, or DLL could not be found.
2. The file permissions on the native layer SO, SL, or DLL
have not been set properly.
3. The native layer SO, SL, or DLL exists, but is either
invalid or corrupted.
For more information, read the installation documentation
for your JDBC Driver, available from:

"thorick" <[email protected]> wrote in message news:<[email protected]>...
Most likely, the OCI libraries could not be loaded.
Before continuing down this path, is there any reason
why you want to use an OCI based Driver as opposed to the
all Java Oracle thin driver ?There is indeed a valid reason for my choice.
I am currently connecting to the Oracle "Rdb" 7.0 database (located on
VMS) - not Oracle Oracle.
The SQL Service software we're currently using is version 7.1. This
version works well with the OCI8 driver (when connecting to the
database from Windows NT). This version of SQL Service however does
NOT work for the THIN driver (unless we upgrade the SQL Service to
version 7.1.5.5 - which we're not prepared to do so because it is not
stable enough from our previous test/trials). SQLSRV Version 7.1.5.5
works for THIN driver but it will result in uncommitted
transactions/unresolved connection/stopping of listener issues and
there is a need to restart the service from time to time. Oracle has
since confirmed that this is a bug that they have yet to resolve...
So we have to stick to OCI8 (THICK) for the time being. I would really
appreciate it very much if you can tell me the various OCI libraries
that I need to load (in terms of WebLogic Server config file settings
etc..).
By the way I have already installed the Oracle 8 client software on
the NT server (where WebLogic Server is) and I have also set up the
relevant SID (using the Net8 Assistant) that points to the Oracle Rdb
database on the VMS. I have also tried using SQL*Plus to connect to
the database and I can connect properly to the database. But WebLogic
simply doesn't seem to load the software.
Help...

Oracle.jdbc.driver.OracleDriver not found in Sun ONE Studio

I get this message when I try to connect to the database while creating an EJB. I have tried adding the path to my CLASSPATH, and to adding it to the various CLASSPATHs within Sun ONE Studio. IDE_HOME is defined correctly but OracleDriver.class is still not found. Anyone know what my problem might be?
Thanks,
Michael A. Moran

Hi Sujatha,
Thanks for responding. My CLASSPATH is as follows:
madonna% echo $CLASSPATH
/export/oracle/jdbc/lib:/export/oracle/jlib:/export/oracle/jsp/lib:/export/oracle/sqlj/lib/runtime.zip:/export/oracle/oem_webstage:/export/oracle/lib/aurora_client.jar:/export/oracle/jdbc/lib/classes12.zip:/export/oracle/sqlj/lib/translator.zip:/export/oracle/sqlj/lib/runtime12.jar:/export/oracle/lib/vbjorb.jar:/export/oracle/lib/vbjapp.jar:/export/oracle/lib/mts.jar:/export/oracle/javavm/lib/aurora.zip:/export/oracle/javavm/utl/ejb/lib/vbj30ssl.jar:/export/oracle/jlib/javax-ssl-1_2.jar:/export/oracle/jlib/jssl-1_2.jar:/export/oracle/lib/servlet.jar:/export/oracle/lib/http_client.jar:/export/oracle/lib/http_server.jar:/export/oracle/oem_webstage/oracle/jdbc/OracleDriver.class:/export/oracle:/export/oracle/jdbc/lib/nls_charset12.jar
Which as you can see includes classes12.zip and /export/oracle/oem_webstage/oracle/jdbc/OracleDriver.class
I have also set all the IDE internal classpath variables to the same settings. It has no effect. I still get the same message.

Am I missing something else?
Jeffrey

Enter this code into your program and then put the Oracle jar file that contains the driver in your run-time classpath.
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
catch(ClassNotFoundException cnfe) {
// driver not found
}The effect of this is that the classloader will load the Oracle driver for you then call it's static initiailizer that does a bunch of magic that results in the Java runtime knowing that there's a JDBC driver out there.
It is a little weird - but that's the way it works.

Thanking you in advance.

1) you don't want to do that in a JSP
2) did you actually add the correct jars to the classpath of your web application? Because if you did, you'd not get this error.
That means adding it to the proper location in your WAR file, as you should have learned when you studied tutorials and books about web application development.

You need to have Oracles JDBC driver available to your web application.
That means the driver (commonly called ojdbc14.jar) should be in either the WEB-INF/lib directory of your web application, or in the [TOMCAT]/lib directory.
However it is generally accepted that Database connections from JSP pages are a bad idea.
Put this logic in java code/beans.
Even better, set up a [JNDI Datasource in Tomcat|http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html] that your web application can access. That way your code can be database independant.

Class Not found : oracle.jdbc.driver.OracleDriver when calling web service

Hi,
I have installed the Oracle Data Integrator Public Web Services on Apache Tomcat 5.5 application server with Apache Axis2
When I try to call the web service OdiInvoke using the operation "listScenario" using only the JdbcDriver as input parameter, the response I get back from the web service call is:
java.lang.ClassNotFoundException: Class Not found : oracle.jdbc.driver.OracleDriver
Using the operator "getWebServiceVersion" I get a successfull response back som the connection seems fine.
Obviously the error has to do with the driver not beeing available but where should I put the driver? Or how do I make it available? When working from Topology Manager, all connections are fine.
Best regards
M

Solved it on my own by putting ojdbc14.jar in the following directory: <Apache-Tomcat install dir>/webapps/axis2/WEB-INF/lib/
Thought I'd share in case some one else has same issue

Oracle.jdbc.driver.OracleDriver cannot be found !

Hi,
I'm using VisualAge 4.0 and WebSphere Application Server 3.5.5
I have an error when i execute my application (with java -jar myapp.jar) :
"Impossible to find jdbc driver class oracle.jdbc.driver.OracleDriver which has been specified"
I have installed an Oracle driver in WebSphere, so what is the problem ??
It's working very well if i start my application in VisualAge
Thanks in advance
Steve

If you use the -jar Option with your application No classpath setting is used. Either place the classes12.zip in the ext directory or class your application without the -jar option.

NullPointerException from oracle.jdbc.driver.OracleDriver.connect()

What is the exact 10g version?
According to MOS note 207303.1, for connection between 11g client and 10g server, there is a minimum version requirement on 10g server side.

NullPointerException at oracle.jdbc.driver.OracleDriver.connect()

I have written a java stored procedure. The method can be executed properly in local PC environment.
but when the java program is load into Oracle DB JVM by loadjava command. such method is called in SQL> prompt as a java stored procedure. I got
java.lang.NullPointerException
at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:379)
at java.sql.DriverManager.getConnection(DriverManager.java:573)
at java.sql.DriverManager.getConnection(DriverManager.java:187)
at WCZSynchronizer.testLocalConn(WCZSynchronizer:901)
as shown in the trace file.
The line in my own java program WCZSynchronizer is simply
Connection conn = java.sql.DriverManager.getConnection(db_connection_string,username,password);
I am sure that the db_connection_string, username and password are correct as it works in my local PC.
I even try to get default connection by
Connection conn = java.sql.DriverManager.getConnection("jdbc:default:connection:");
and
Connection conn = new oracle.jdbc.driver.OracleDriver().defaultConnection();
I got the same NullPointerException in both cases too.
In fact, the java stored procedure worked before. but suddenly it's failed! The Oracle DB server is under my control and I did not change any configuration nor setting on it.
I can't find similar case from this forum. Do any one know why?
thanks.

First try debugging the test case by making sure that none of the parameters passed to getConnection is null.
When you are sure that none of the parameters are null, if the issue still reproduces. Let us know
- The driver version
- The jar file you are using
