Couldnt load database driver: oracle.jdbc.driver.OracleDriver

Hi,
I could appreciate some help here.
I have saved my classes12.zip and nls_charset12.zip in my c:\work\WebDev and I have added this to my classpath. But when I run my servlet, I still get the error of "Couldnt load database driver: oracle.jdbc.driver.OracleDriver"
I also tried using jar files but still got the same error.
Any sggestions to solve this?
Thanks!!

If it is Tomcat, extract the classes12.zip and place
in the tomcat-home\common\classes folder.
I am rather certain that it does not need to be extracted. I am also rather certain that the documentation for Tomcat points out the correct way to install it (which includes changing the extension from zip to jar.)

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;

nother pool: MultiTransactionTestHi. You can't domultiple DBMSes in one transaction unless you use an XA driver and
an XA transaction. Your workarounds are:
1 - Use an XA driver, datasource, and tx
2 - If you're just reading, you can use non-transactional datasources. Do make sure you
always close your connections...

Oracle jdbc driver problems in netbeans 5.5

need help again....i'm experience a problem. the problems are :
i connect from netbeans 5.5 to oracle database express client 10g using jdbc driver ojdbc14.jar. the connection succeded (all the tables appears and i even can view the data). but when i trying to bind data to a drop down list component (with right click to the dropdown list component and then bind data), the dataprovider of that table appear in red color and there's no field appears in that. i'm so confused? i already add the ojdbc14.jar driver to the following path :
1. i create a new class library in netbeans with consist of that driver,
then added to my project (right click in my project then add library).
2. then i added the ojdbc14.jar driver to my tomcats lib at "C:\Program
Files\netbeans-5.5\enterprise3\apache-tomcat-5.5.17\common\lib".
Is there any additional settings in using oracle jdbc driver? Does anyone knows? thanks a lot for the answers...

Hi!
I'm using NetBeans 6.5 and I'm having some troubles to connect.
The steps I've made:
- Create the connection pool in Glassfish, nothing special, just standard parameters (Based on javax.sql.DataSource and including URL, Username and Password).
- Create the JDBC resource associated with that connection pool,let's say jdbc/test.
Now in NetBeans I register the driver:
- New driver -> Find the ojdbc14.jar and from the options that I can choose it shows: oracle.jdbc.OracleDriver and oracle.jdbc.driver.OracleDriver.
If i choose without +.driver+ I got the thin drivers (the ones i want) and if i chosse the one with the other one I got the OCI drivers. So I choose the first option oracle.jdbc.OracleDriver
- Then I go to my project and click New -> Entity Classes from Database and from Datasource I select jdbc/test and it shows the following error message:
Unable to find the driver oracle.jdbc.driver.OracleDriver. Please register this driver in the Databases.
I can fix it if while registering the ojdbc14.jar I select the second option (*oracle.jdbc.driver.OracleDriver*) but with this option I need to specity the connection to use OCI instead of the desired thin driver.
I hope you'll understand and help me somehow

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

Oracle jdbc driver class and classes12.jar whether deprecated.?

Hi All,
1. In one of the post, it has been told that oracle.jdbc.driver.OracleDriver will be deprecated and also recommended to used oracle.jdbc.OracleDriver.
According to that post, I changed the driver class name in my code as below:
Class.forName("oracle.jdbc.OracleDriver");
Then to check the driver name, I insert the below code:
Enumeration<Driver> driverEnum = DriverManager.getDrivers();
+while (driverEnum.hasMoreElements()){+
System.out.println("driver : "driverEnum.nextElement());+
+}+
Below is the output:
driver : oracle.jdbc.driver.OracleDriver@addbf1
Even after specifying the driver class name to be used as oracle.jdbc.OracleDriver, why it is taking oracle.jdbc.driver.OracleDriver..?
INFO : The Oracle JDBC Driver (classes12.jar) version is 10.2.0.4.0.
2. We are using classes12.jar for developing all JDBC code. In Oracle Database 11g Release 2 (11.2.0.2.0) JDBC Drivers, there is no classes12.jar. Is this deprecated? Which jar can be used instead of classes12.jar?
Thanks in advance.

Oracle jdbc driver spending 40 seconds to make connection to Oracle db 11g

we are using weblogic 10.3.3 and teh default Oracle11.1.0.7 Driver ojdbc6.jar to talk to Oracle db 11.2.0.1
After reviewing weblogic logs I see that it takes 50 secodns for each connection to db
HHere is a snippet (note I put in a 10 sec login dleay as i was experimenting, butt eh problem still occurs with or without login delay)

<Dec 21, 2010 1:29:09 AM GMT> <Info> <JDBC> <BEA-001068> <Connection for pool "acm_repository" created.>
There is someting wrong in this environment
I donwloaded the _g version fo teh exact same driver and had weblogic use it so I could generate verbose logs
Here is a snippet fo teh oracle drivers verbose log file . If you notice the key parts
it seems like its spending 40 second to make the connection, goes into a setConnectionDuringExceptionHandling method and creates the connection
can someone shed light on what causes itto go into an exception state
This happens for each and every connection but only in one specific environment
we have other environments which seem towork fine with the exact same product versions except for this environment
Thank you for any guidance on troubleshooting this further

I would file an oracle jdbc bug to begin with, but I am guessing the driver is simply waiting
for the DBMS to respond, so yo may need a good DBA to see what the DBMS thinks is going
on at the time. I did hear of a case where the DBMS was doing some auditing, logging
some info during every login. This info was being written to an OS file which just happened
to be remote-mounted and would occasionally take 30 seconds, which caused connection
requests to timeout at the driver end.... WebLogic is just asking the driver for a connection
using your properties, so it's not involved directly with the problem....

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...

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.

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

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

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.

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.

I use Java Web Service Developer Pack 1.0 on Win98 SE, database Oracle 8.1.7 is installed on dedicated IBM server (AIX 4.x).
I put these lines in autoexec.bat:
set PATH=C:\Perl\bin\;"C:\j2sdk1.4.0\bin";%PATH%
set CLASSPATH=.;C:\j2sdk1.4.0\lib\tools.jar;C:\j2sdk1.4.0\lib\classes12.zip;C:\j2sdk1.4.0\lib\classes111.zip;%CLASSPATH%
set CLASSPATH=C:\jwsdp_1_0\common\lib\servlet.jar;C:\jwsdp_1_0\common\lib\jasper-compiler.jar;C:\jwsdp_1_0\common\lib\jasper-runtime.jar;%CLASSPATH%
set JAVA_HOME=C:\j2sdk1.4.0

I have the same problem. I created a JSP page that uses a class to retrieve database information. I added a main method to the class so I would be able to test it. When I test the class using the main method the method returns all the information from the database. When I try it using Tomcat, I get the following error: java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver
Does anyone have an idea of what is going on?
My CLASSPATH configuration is the same.

CLASSPATH=/tools/oracle/9.2.0/jdbc/lib/ojdbc14.jar
