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.

JDBC Adapter Error - SAPClassNotFoundException: oracle.jdbc.driver.OracleDr

Hi,
I am trying to implement JDBC to File scenario.
Trying to connect to Oracle Database. Oracle drivers are installed on XI server
JDBC Adapter parameters:
JDBC Driver - oracle.jdbc.driver.OracleDriver
Connection - jdbc:oracle:thin:@10.25.228.156:1521:databaseName=XE
Error which I can see in Communication Channel Monitoring is:
Error during database connection to the database URL 'jdbc:oracle:thin:@w4inpusyga6:1521:XE' using the JDBC driver 'oracle.jdbc.driver.OracleDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Cannot establish connection to URL 'jdbc:oracle:thin:@w4inpusyga6:1521:XE': SAPClassNotFoundException: oracle.jdbc.driver.OracleDriver'
All your inputs are welcome!
Thanks

Hi
we are integrating XI with IBM DB2 database.
we have used 2 Jar files ( DB2jcc4.jar & DB2jcc.jar ).
but after deployment the jar file was deployed in different location, not in D:\usr\sap\XR3\DVEBMGS00\j2ee\cluster\server0\bin\ext\
trying many times this deployment, we manually copy/paste
our driver jar file to legitimate directory..
Now the error has change as .UnsupportedClassVersionError: com/ibm/db2/jcc/DB2Driver (Unsupported major.minor version 50.0)
Any one could through some light on it..
Regards,
Ashutosh

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...

Load Oracle JDBC Driver by reflection.

Hi!
I'm trying to load driver by reflection like this,
try {
URL ora8libURL = new URL("file:///C:/oracle/product/10.2.0/clientDev/jdbc/lib/classes12.jar");
Class.forName("oracle.jdbc.OracleDriver", true, URLClassLoader.newInstance(new URL[]{ora8libURL}));
    Enumeration<Driver> drivers = DriverManager.getDrivers();
    while(drivers.hasMoreElements())
      Driver drv = drivers.nextElement();
      System.out.println(drv.getClass().getName());
conn = DriverManager.getConnection("jdbc:oracle:thin:@//192.168.186.13:1521/rdb817","user","password");
catch(ClassNotFoundException ex) {ex.printStackTrace();}
catch(MalformedURLException ex) {ex.printStackTrace();}
catch (SQLException ex) {ex.printStackTrace();}but i've got this error:
sun.jdbc.odbc.JdbcOdbcDriver
java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@//192.168.186.13:1521/rdb817
     at java.sql.DriverManager.getConnection(Unknown Source)
     at java.sql.DriverManager.getConnection(Unknown Source)
...However, when i specify driver explicit in classpath it works fine.
Help.

I had the same problem you have, until i read your post :-).
Now, with your help, i found a solution.
The problem with your code is that the DriverManager that you are using doesn't "see" the driver you are loading. But you can create the driver instance directly:

}Has you can see, the DriverManager doesn't know about the divers loaded with the new ClassLoader.
The only thing you have to pay attention is not to have the classes for "oracle.jdbc.OracleDriver" in your system classpath.

"Error loading native JDBC driver library" received when connecting to a DB

I recently installed 10g client onto my PC. After installation I now recieve an "Error loading native JDBC driver library" error when attempting to connect to a database.
This is a dual core Dell loaded with XP sp 2. I am attempting to connect to a 10gR2 instance. I tried the solution mentioned in another post to no avail. I am using SQL Developer v 1.2.1 build main-32.13.

For those who can get SQL Developer to work, could you please detail what properties you have in your installation? Could you please describe what we are supposed to see in the SQL Developer Properties tab? I found this tab in Help>About>Properties but have no idea where SQL Developer picks up those attributes. And it does not seem we can change any of them within SQL Developer. How frustrating!
Even more frustrating is that I am able to access the database I want to connect to with SQL Plus (right click on the connect node in SQL Developer)...
Thanks,

Win2000+weblogic510+oracle8i,Could not load 'oracle.jdbc.driver.OracleDriver'

星期四 三月 23 20:30:17 GMT+08:00 2000:<E> <JDBC Pool>
Failed to create connection pool "ejavaPool"
weblogic.common.ResourceException: Could not load 'oracle.jdbc.driver.OracleDriver'
because
System.loadLibrary threw java.lang.UnsatisfiedLinkError
with the message 'oracle.jdbc.driver.OracleDriver'.
This could occur if the JDBC driver is not in the weblogic.class.path.
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 environment.
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.

any idea?

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.

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 {

// Close the result set, statement, and the connection
rset.close();
stmt.close();

Hi ,
In first look it seems a classpath problem. Means that your DB driver is not in the current class path .
But if it is not that the try to find the exact exception for that use exception's printstacktrace() and get the exception message . So in the following block of of code put e.printstacktrace()
catch(ClassNotFoundException e) {
out.println("Couldn't load database driver: " + e.getMessage());
}

ORA-24816 error with oracle 10 driver

Friends,
I am getting the following error with Oracle 10 driver while trying to insert data > 4k into a LONG column. The table also contains another column of type varchar2(4000). The code works perfectly fine with Oracle 9i driver.
ORA-24816: Expanded non LONG bind data supplied after actual LONG or LOB column
Kindly let me know if this is a programming error or a driver problem.
Thanks,
Vinay

this driver you mentioned, is it the jdbc driver?
ORA-24816:     Expanded non LONG bind data supplied after actual LONG or LOB column
Cause:     A Bind value of length potentially > 4000 bytes follows binding for LOB or LONG.
Action:     Re-order the binds so that the LONG bind or LOB binds are all at the end of the bind list.

Load oracle jdbc driver error when run applet via the web

Hi All,
I have built an applet which connect to database via jdbc thin driver. It works fine when I run it through the applet viewer, but got a problem when run it through the web.
java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver
I am using jdev9i 9.0.4 and jdk 1.4.2. The jdbc version is 9.0.1
I have added both the classes12.zip and ojdbc14.zip in the class path and also pack them together with my applet class. Here is the code
public class MyApplet extends Applet
implements Runnable
public void start()
if(theThread == null)
theThread = new Thread(this);
theThread.start();
Retrieve R = new Retrieve();
this.MyMap = R.retrieveDesc();
public class Retrieve
public Retrieve()
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn=DriverManager.getConnection("jdbc:oracle:thin:@babyruth.wvu.edu:1703:devdw", User, Password);
conn.setAutoCommit(true);
connectStatus = true;
public HashMap retrieveDesc()
return map;
I have also built one HTML page NewApplet like this
<HTML>
<HEAD>
<TITLE> My New Applet</TITLE>
</HEAD>
<APPLET CODE="MyApplet.class" CODEBASE="menu" ARCHIVE="MyApplet.zip" WIDTH=300 HEIGHT=485>

<param name="bgcolor" value="255,255,255">
</HTML>
Any advice is highly appreciated
Mei

Sir,
Well you haven't "packed" them correctly. Why don't you just add the driver bits to the soucebase tag? or something like that anyway...
Sincerely,

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.

Steps to load Oracle JDBC Thin driver onto Tomcat

I have Oracle JDBC working with thin driver on my local Tomcat container and now need to put it on a server but forgot how I set it up and want to make sure I do it correctly when I put it on the server.
Please advise if this is correct?
1- Load the thin driver (ojdbc14.jar ) in Tomcat 4.1.27 Container into the common/lib directory
2- Set the classpath on the Windows server to allow me to use the ojdbc14.jar driver?
If so then I need to do this using Windows DOS where I add the thin driver to my Classpath?
Set CLASSPATH=%CLASSPATH%;C:\TomcatHome\common\lib\servlet-api.jar;C:\TomcatHome\common\lib\ojdbc14.jar
Or do I NOT need to set the classpath and just restart the Tomcat container??

Thanks,
I loaded the ojdbc14.jar file in common/lib and restarted the container and I can now connect to Oracle.
What you mean by not needing ojdbc14 for compilation and it would be better to use a build tool[b] to do what?

Web Logic 6.1 JDBC Pooling with the Oracle Thin Driver

Hi,
We're slowly getting through a WebLogic 4.5.1 to 6.1 conversion for a small application
at my company. Initially, we had trouble getting the Oracle thin driver working.
We've finally cracked this nut. Now we're trying to get pooling working, and
cannot find an example of doing this with the Oracle thin driver.
Would anyone be able to provide:
1. the portion of the config.xml that pertains to building a connection pool using
the Oracle thin driver
2. the two lines of code for loading the driver and getting a connection from
this pool
i.e.
Driver d = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Connection c = d.connect("jdbc:weblogic:pool:myPool", null);
Thanks very much!

You don't usually edit the config.xml unless it is absolutely necessar. Instead,
you can config the pool in the GUI admin console, quite easily. After you successfully
configed the pool in the console, it is written into the config.xml file for you.
Only thing special when config the pool is the name of the driver and the url.
url: jdbc:oracle:thin@dbhost:dbport:dbinstance
driver: oracle.jdbc.driver.OracleDriver
If you prefer, you can also config the pool from the command line. It is detailed
in the "Weblogic Server Command-line Interface Reference".
2. the two lines of code for loading the driver and getting a connection
from
this pool
i.e.
Driver d = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Connection c = d.connect("jdbc:weblogic:pool:myPool", null);
Again, you don't use the connection directly. Instead, you use "Data Source".
Data source in weblogic is just a connection object factory associated with a
JNDI name. You can therefore lookup the data source with the JNDI name and from
the data source object, you get the connectin object. No need to explicitly load
the driver class.
There are plenty of example codes available in the weblogic examples installed
with 6.1, that uses the data source.
