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

Could not load 'oracle.jdbc.driver.OracleDriver
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:

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...

If you are trying to use the thin driver you need to make sure you have the
classes12.zip file in the weblogic server classpath. You can download this
driver from Oracle website.

you must be having an administrative console for iplanet
there the classpath can be set to the required location
Open the Administrative console for it..

Runtime error - class not found using JDBC driver and thin client

Hi,
We are running a small Java application on a Sun server which acts as a thin client connecting to an Oracle 8i server running on a different server.
JDK version: 1.3.1_01
OS version: Solaris 7
JDBC classes file: classes12.zip
It compiles fine, but get a runtime error (the DriverManager.registerDriver method )
cruncher [40]% javac -classpath /export/home/mrscot/classes12.zip JDBCtest.java
cruncher [41]% java JDBCtest
Exception in thread "main" java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver

Any ideas? Probably something very, very stupid I'm overlooking!
Thanks

Supplementary question:
Hi,
We are running a small Java application on a Sun server which acts as a thin client connecting to an Oracle 8i server running on a different server.The Oracle version is 8.1.6
Will the 'classes12.zip' for 8.1.7 work with
1.3.1 of the Java JDK, and Oracle 8i 8.16 ??
Thanks Scotty

Bug in Oracle JDBC Driver: NullPointerException when calling clearParameters

There is a bug in the latest version of the JDBC driver that throws a NPE when calling PreparedStatement.clearParameters(). I don't need a response to this, since I have a workaround (just catching and ignoring the exception), but it should probably be fixed. I speculate that the problem only occurs when you try to call clearParameters() more than once on the same PS, but I haven't confirmed it.
It is probably an easy fix. Following is the stack trace:

Take a look at the method that is causing the NullPointerException:
public void clearItem(int i)
if (!m_dynamic && m_vector == null && i < m_vector.size())
m_vector.removeElementAt(i);
if (m_items != null && i >= m_items.length)
return;
m_items[i] = null;
return;
A NullPointerException will be thrown whenever clearParameters() is called when no parameters have yet been bound.
The first IF statement should read:
if (!m_dynamic && m_vector != null && i < m_vector.size())
A simple workaround would be to make sure that your parameter list is never empty before calling clearParameters(). Is there a patch for this anywhere?

Class Not Found: JDBC driver oracle.jdbc.driver.OracleDriver

Does anyone can help?
When I install the OpenBravo, I get the error shown below:
Class Not Found: JDBC driver oracle.jdbc.driver.OracleDriver could not be loaded.
I am using the Oracle XE, jdk1.5.0_06, Apache Tomcat 5.5.17.

include the jar file classes111.jar in your classpath, it will work
The location would be like
C:\Applns\oracle9204\jdbc\lib\classes111.jar;
set the classpath with this jar in command prompt
set CLASSPATH=%CLASSPATH%;C:\Applns\oracle9204\jdbc\lib\classes111.jar;

JDBC driver - Class oracle.jdbc.driver.OracleDriver not found.

Greetings:
When I tried to compile an test script (as attached below) to test the driver, I always ended up with the following error message:
....java:17: Class oracle.jdbc.driver.OracleDriver not found.
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Could somebody shine some light on it? I would very much appreciate it.
By the way, I have an Oracle DBMS (8.1.7) with jre1.1.7. My Java is jdk1.2 and the driver is ocijdbc8.dll
Wil
*************** The test script *************
import java.sql.*;
class Users
public static void main (String args [])
throws SQLException, ClassNotFoundException
// Load the Oracle JDBC driver
Class.forName ("oracle.jdbc.driver.OracleDriver");
// Connect to the database
// You can put a database name after the @ sign in the connection URL.
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@US10", "QM24202E", "QM24202E");
// Create a Statement
Statement stmt = conn.createStatement ();
// Select ... table
ResultSet rset = stmt.executeQuery ("select USERID from USERS");
// Iterate through the result and print the ... names
while (rset.next ())
System.out.println (rset.getString (1));

check out what thomas Fly wrote on another discussion forum about connection with JDBC, i tried it and i haven't gotten it
to work yet but at least i don't have the "... not found" error,
you should try it too, and i think it's good to tell you that i
still haven't installed the oracle client on my windows Me PC.
Hope this help you
This may help also... I have Oracle installed on a Linux PC at 192.168.1.4 on my LAN, listening on port 1521. I can connect from another PC (Linux / Windows ME dual boot, though running Windows at the time of this experiment) using the following program:
import java.sql.*;
public class sqlLookup {
public static void main(String[] args) throws SQLException, ClassNotFoundException {
String dbUrl = "jdbc:oracle:thin:@192.168.1.4:1521:ORA8";
String user = "thomasfly";
String password = "maverick";
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection c = DriverManager.getConnection(dbUrl, user, password);
Statement s = c.createStatement();
// SQL code:
ResultSet r = s.executeQuery("select * from members");
while(r.next()) {
// Capitalization doesn't matter:
System.out.println(r.getString("Name") + ", " + r.getString("id") + ": " + r.getString("email") );
s.close(); // Also closes ResultSet
I downloaded classes12.zip for Oracle 8.1.7 and put it into the C:\Windows directory, and mounted C:\Windows\classes12.zip in Forte for Java (equivalent to adding it to the classpath if I were running the program from a DOS window, rather than in Forte).
ORA8... capitalization may be important... is the name of my database, which may be found in the tnsnames.ora file in $ORACLE_HOME/resources.
The query gets the Name, id, and email fields from the table "members" in the database.
This is just a barebones program, and each time it's run, the Oracle listener has to be stopped and restarted before the program can be successfully run again.

Error class not found with Class.forName("oracle.jdbc.driver.OracleDriver")

sorry Got the solution...!!!!
Hi
I am trying to connect to oracle database on the server, oracle client installed on working m/c, I have placed classes111.zip (from oracle 8) in jdk1.1.8demojrelibext folder and I have set the classpath to the ext folder. The code
try
Class.forName("oracle.jdbc.driver.OracleDriver");
catch(Exception e)
when I run this code , error as

Please reply what are settings I should to to load this oracle driver,
Thanks

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.

Please help to suggest me. How should I do to let out this error?
Thanks

many people use the two interchangeably, though technically it can mean something different.
What you get back from a call to newInstance() is the same as what you'd get when using the new keyword and no constructor arguments, a reference to an instance of a class (there are other ways to dynamically create an instance using other constructors).
"Creating a class object" technically means loading the class which causes a Class instance (so an instance of the class Class) to be created for that particular class, making the class available to the JVM for instantiation of instances.
newInstance() and its sisters are useful for when the class to be instantiated is not known (or even doesn't exist) when compiling the class that needs to instantiate it.
This is of course the case with JDBC. The people creating the JVM can't know what driver classes will be out there at some point in the future (and if they did know and have access to all of them in the past it would still be foolish to have them all hardwired into the JVM).

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.

Oralce 10G2 JDBC Driver - Error Loading oracle.jdbc.driver.OracleDriver

When attemping to use the 10G2 jdbc driver the following NoClassDefFoundError is encountered:
Exception in thread "main" java.lang.NoClassDefFoundError: while resolving class: oracle.jdbc.driver.OracleDriver
<<No stacktrace available>>
Caused by: java.lang.ClassNotFoundException: oracle.security.pki.OracleWallet not found in [file:./, file:ojdbc1410g2.jar, file:/usr/share/java/libgcj-3.4.4.jar, file:./, core:/]
<<No stacktrace available>>
The error does not occur when reverting back to the 9 jdbc driver. Does anyone know what is causing this behavior?
Regards,
Paul

Paul,
Actually, class "oracle.jdbc.OracleDriver" extends class "oracle.jdbc.driver.OracleDriver".
So check the JAR files in the list displayed by your error message and see if any of them contain the [missing] class, for example:
jar tvf ojdbc1410g2.jar oracle/jdbc/driver/OracleDriver.classGood Luck,
Avi.
