Failure loading native JDBC driver

When i go into sql developer and try to create a connection for oracle using TNS connection identifier i get a failure loading native JDBC driver. any ideas?
thanks

Can you create a basic connection? Which platform are you on? What version of sqldev are you running? What version of JDK do you have?

"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.

Hi,
I found this thread from googling and am having the same problem for four days now...
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,

Help - Could not load 'oracle.jdbc.driver.OracleDriver ...

I'm using oci8 to connect to the Oracle database.

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.

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.

Question about load Microsoft JDBC driver for Sql server 2000

Hello,
I have some problem while trying load the sqlserver2000 jdbc driver
My program is a third party application and it works with the other type 4 JDBC driver well. So I tried to use Microsoft SQL server 2000 JDBC driver instead.
I installed JDBC driver and set up the classpath.
My error message is:
"Driver class 'com.microsoft.jdbc.sqlserver.SQLServerDriver' could not be loaded"
Is above message means that my classpath setup correctly but the application could not load the class or the application could not find the jar file which containes the driver class?
By the way, the third party application I was using to load this JDBC driver does not certified to use microsoft JDBC driver. But I don't think it matter?
Thanks for your help

Hello,
I have some problem while trying load the
sqlserver2000 jdbc driver
My program is a third party application and it works
with the other type 4 JDBC driver well. So I tried to
use Microsoft SQL server 2000 JDBC driver instead.
I installed JDBC driver and set up the classpath.
My error message is:
"Driver class
'com.microsoft.jdbc.sqlserver.SQLServerDriver' could
not be loaded"
That is an unusual message. Presumably you did not see "NoClassDefFoundError". If you see that it means the class could not be found.
Is above message means that my classpath setup
correctly but the application could not load the class
or the application could not find the jar file which
containes the driver class?
By the way, the third party application I was using to
load this JDBC driver does not certified to use
microsoft JDBC driver. But I don't think it matter?
It could. Perhaps the app expects a certain functional level and the driver doesn't support that. And so it bails with the message that you see.
Or it could mean that you have do something special because it has its own class path, and the driver is not in that.

Separating native JDBC driver JAR from applet JAR - best way?

Since I want to allow the customers/users of my applet to choose their own native JDBC driver to purchase at their site, I don't bundle the JDBC driver into my applet's JAR file. During my testing, here's what I've done:
1. Deployed my applet HTML and JAR files to a web server folder.
2. Extracted my JDBC driver JAR file's contents to that same web server folder.
(My applet HTML contains 2 parameters that allow the applet to use the JDBC driver -- class name and connection string template.)
This works fine, but I'm wondering if I'm using the best techniques.
Questions:
1. Do the contents of the JDBC driver need to be extracted from its JAR file? If not, what do I do, if anything, to allow my applet to "see/find" the driver class within the JAR?
2. If the JDBC JAR file DOES need to have its contents extracted, is there a way to extract them to a central folder somewhere on the web server and have a variety of applets use them? If so, what do I need to do to make my applet "see/find" the file(s) in the central folder?
Possibly looking for this stucture on the web server:
/WebApps/JDBCfiles
/WebApps/MyDbApplet1
/WebApps/MyDbApplet2
/WebApps/MyDbApplet3
Any advice/recommendations? Thanks.

Is it possible for a client application to access a jarred JDBC driver? I'd like to deliver a JDBC driver packed in a jar file, however, it won't work, here is what I am tring to do
try {
Class.forName("mfg.jdbc.myDriver").newInstance(); //--> throw an exception
m_Connection = DriverManager.getConnection(szURL, props);
catch(Exception e) {/...}
Before class myDriver and other classes from package mfg.jdbc were jarred, a client application used to get the connection just fine, now I get an exception "java.lang.ClassNotFoundException: mfg.jdbc.myDriver"
I am using Java 2 Platform, no problem in running a jarred command like java -jar jarredclass.jar
Any tips and hints would be gratfully received!

database but if faced 2 problems
1- I don't know the name of the jdbc driver. if any
body can show me how can i know it.
It depends on what driver you are using. Look it up and search the Oracle site. Or look through the gazillion examples in the JDBC forum.
2- when connecting to the database i have to provide
the server name and the port number unfortunatly i
don't know both.
Talk to your DBA. There is no way we could or should be able to help you on this one.

Pre-loading a JDBC driver

Hi, is there a simple way to load a JDBC driver in Tomcat at startup, to avoid the call to Class.forName() in every JDBC page that accesses the dB?
I also would like to change it when I like in a simple way, say something like changing a property file, if possible.
Thanks for your help.

Geez, use a connection pool.In fact I'm planning to do it
>
Tomcat lets you set up a JNDI data source for your
app. Go read those docs. - MODThanks for the advice.
Are you sure? I would have thought you'd only have to load the class >once.In fact I would like not to ever load it in my pages...

SWING GUI blockes when doing a DB action with microsoft nativ JDBC driver

hi,
in a bigger project i have the problem that if i perform a DB action the GUI is blocked. It does not matter if i do the DB Action in invokeLater or
in a SwingWorker or in a new Thread if i call the DB Action and i move another window over my window it is not refreshed.
normally the GUI shouln�t be blocked if i use invokeLater. maybe it
has something to do that i use the native DB driver? I am using JDK
1.4. has anyone ever encounterd the same problem?
alex
package swingtest;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.sql.*;
public class GUIProblem extends JDialog {
// this method does a simple DB call to generate some load
public void doMyDBCall()
try {
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection con = DriverManager.getConnection ("jdbc:microsoft:sqlserver://abgvdr71:1433;databasename=v52li;","sa","");
Statement question0 = con.createStatement();
ResultSet rs0=null;
rs0 = question0.executeQuery("select * from intercept_24");
boolean more=rs0.next();
while (more) {    more=rs0.next();}
catch (Exception sql)
{ sql.printStackTrace(); }
public void doItinvokeLater()
SwingUtilities.invokeLater(new Runnable(){    public void run(){
doMyDBCall();
public void doItSwingWorker()
SwingWorker worker = new SwingWorker() {
public Object construct() {
System.out.println("worker start");
doMyDBCall();
return null;
worker.start();
System.out.println("finished .....");
Object view = (Object) worker.get();
public GUIProblem (){
super((JFrame)null,"",true);
JButton button = new JButton("do it");
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event)
// calls it direct -> GUI blocked
//doMyDBCall();
// with invoke later -> GUI blocked
//doItinvokeLater();
// with the swingWorker -> GUI also blocks
doItSwingWorker();
getContentPane().add(button);
setSize(200,200);
setVisible(true);
public static void main(String [] args)
{ new GUIProblem(); }
}

The invokeLater runs the Runnable in the event thread, so yes, that will block your GUI. You ALMOST got the SwingWorker right. DB call in the construct() method -- the construct() method executes outside the event thread, the finished() method executes in the event thread. The only problem is, you did a worker.get() method in your event thread (right after worker.start(0, and get() blocks until result is ready from construct() -- so, bingo, you're jammed up waiting in you event thread.

Porblem loading Microsoft JDBC Driver for SQL Server

Hi all !!
Well, it seems there is a naming problem for the MS Driver, when Netbeans creates server resources for the Connection Pool and the DataSource, the default name for the connection pool's datasource classname is com.microsoft.jdbc.sqlserver.SQLServerDataSource, but the actual name of the class within the driver's jar is com.microsoft.jdbcx.sqlserver.SQLServerDataSource, note the 'x' after jdbc.
I changed this and the resource is created correctly (from the admin console, it pings to the DB server), but when I try to deploy the project, I get this error:
RAR5038:Unexpected exception while creating resource
RAR5117 : Failed to obtain/create connection. Reason : Class name is wrong or classpath is not set for : com.microsoft.jdbc.sqlserver.SQLServerDataSource
RAR5114 : Error allocating connection : [Error in allocating a connection. Cause: Class name is wrong or classpath is not set for : com.microsoft.jdbc.sqlserver.SQLServerDataSource]
WebModule[WebApplication2]java.sql.SQLException: Error in allocating a connection. Cause: Class name is wrong or classpath is not set for : com.microsoft.jdbc.sqlserver.SQLServerDataSource
java.lang.RuntimeException: java.sql.SQLException: Error in allocating a connection. Cause: Class name is wrong or classpath is not set for : com.microsoft.jdbc.sqlserver.SQLServerDataSource
I guess I must change the name of the classname in some other place, but I searched the admin colsole and Netbeans and failed to find where it should be.
I'm using Netbeans 5.5 and SQL Server 200 with the MS JDBC Driver sp 3.
Thanks in advance,
Daniel

Thanks for your answer !!
Yes, the datasource classname is correct in domains.xml.
I had the driver files copied into Appserver/lib, now I placed them also where you suggested me and restarted the server.
Now I get a different error:
LDR5202:Exception in EJBClassLoader

I guess it may have something to do with any of the classpathes, there is a system or environment CP, one for the App server (with prefixes, suffixes, etc, and there is another in the Netbeans IDE tools Options....
I also tried to debug into java.io.WinNTFileSystem.canonicalize0(Native Method) just to see the name of the file who raised the exception, but I couldn't attach the BPEL debugger, it gives me this error:
11:57:24 Connecting to localhost:3343
11:57:24 Unable to start a debug session : Unable to connect to localhost:3343 : Connection refused: connect
I'm using a proxy but the system settings are set to not use the proxy for localhost addresses and so is netbeans.
How much I miss the simplicity of the old Turbo Pascal days !!
Thanks for your help !!

Accessing Informatica File Archive Service using its native JDBC driver

Good morning,
Using the Informatica ILM suite, we've retired a number of database applications (which ran on Oracle) into the so-called Optimized File Archive, or OFA.
The information stored in there can be accessed using their File Archive Service, or FAS.
To allow access for certain tools, they've also got an ODBC and JDBC driver (from the original company that created the archive bit, RainStor), to be able to get to tables in archives.
I've been able to set it up for Aquafold's Aqua Data Studio (ADS), but given that that is shareware I've only got an evaluation version, expiring in 2 weeks.
Since SQLdeveloper, like ADS, is a Java-based tool, and it also allows for third party JDBC drivers, I'm inclined to think that somehow SQLdeveloper should also be able to connect to those archives. Unfortunately, I always get an error message: "Invalid connection information specified. Verify the URL format for the specified driver"
There are some slight differences between ADS and SQLdev in setting up such a JDBC connection.
In ADS, apart from providing user/pw, I have to specify following:
- name of the JDBC driver ("com.simba.client.core.SimbaJDBCDriver")
- location of the JDBC driver (e.g. "C:\Ora\RainStorJDBC-3.0.1.2.jar")
- JDBC URL of format "jdbc:simba://<host>:<port>;Archive=<archive>;ConnectionTimeout=3600;Parser=ORACLE"
In SQLdev I can import the JDBC driver (menu > Tools > Preferences, then under Database > Third Party JDBC Drivers), and in the Database Connection Screen create a new connection, provide the user/pw of the so-called Service Manager (from FAS), and choose Connection Type "Advanced" to then specify the "Custom JDBC URL", which would have to be the same as above. If I test the connection, I get an instant error:
"Status: Failure -Test failed: Invalid connection information specified. Verify the URL format for the specified driver".
Informatica's Global Customer Support are saying that SQLdev can't do it, but I'm just wondering whether some really bright lights in the Oracle community have found an alternative route to be able to connect to such FAS/OFA archives. Given the similarities between ADS and SQLdev, to me it seems it - somehow - has to be possible as well...
Thanks in advance for thinking about this problem/challenge.
Cheers!

Did some further investigations, on other third party drivers. Those ones (e.g. for SQL Server) - when loaded - create an extra tab in the connection screen.
The RainStor JDBC driver does not do that, and I can imagine that that's where it falls short.
If indeed the case, what could be done to overcome this?

Hi,
Did some further investigations, on other third party drivers ... If indeed the case, what could be done to overcome this?That is the case. Currently browsing and migration support for third-party databases is limited to the following:
http://www.oracle.com/technetwork/developer-tools/sql-developer/supportedmigplatforms-086703.html
See section 1.1 for currently supported databases and section 1.3 for those planned for a future release.
To see an example of some (all?) of the extra bits needed to support browsing of a third-party database, find the extensions directory in your SQL Developer installation, look for
oracle.sqldeveloper.thirdparty.browsers.jarthen browse it to see the various class, properties, and xml files necessary for supporting connections to databases like mysql or sybase. You may conclude adding browsing support is not all that complicated. Migration support is an entirely different matter, however. Oracle is the thirdparty.browsers extension owner. Support for more third-party databases would normally be added by the SQL Developer group based on a database's general popularity or a feature request on the SQL Developer Exchange -- obviously a long-term proposition.
If you look at the [Extensions Exchange|http://www.oracle.com/technetwork/developer-tools/sql-developer/extensions-083825.html] maybe you can get some ideas how best to proceed if you have the resources to build your own extension to support RainStor.

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.

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,
Slappy

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.
