Cann't load Oracle driver from servlet

I develop a servlet with VisualAge.
This code works fine:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbc:odbc:SCOTT";
Connection con = java.sql.DriverManager.getConnection(url, "SCOTT", "TIGER");
But I cann't load Oracle driver. I suppose it is path problem. In option of my application I have set path to
classes12.zip, nls_charset12.zip and rt.jar.
But there isn't option ClassPath for Servlet in VisulaAge.
What can I do?

What do you use to test your servlet?
In Visual Age, i use WTE (WebSphere Test Environement). You can find it in WorkSpace - Tools - WTE.
In WTE, click on servlet engine. You have 4 buttons on the right (sorry i use the french version so i do not know theirs english label) use the last one to change classpath.

ClassNotFoundException raised when attempting to load Oracle Driver in jsp

ClassNotFoundException occoured when attempting to load Oracle Driver in jsp
I am using oracle 9i server.here is the code that i have try
Connection connection = null;

connection = DriverManager.getConnection(url, username, password);
catch (ClassNotFoundException e)
// Could not find the database driver
} catch (SQLException e)
// Could not connect to the database
can i have to set classpath for this, pls help me.

Do not modify the serverclasspath in WebServer 6.1.
Add the path to the driver to the classpathsuffix attribute.
change
classpathsuffix=""
to
classpathsuffix="/usroracle/driver/classes12.zip" (Unix)
or
classpathsuffix="C:/Oracle/driver/classes12.zip" ( Windows )
Replace the path in the example with the actual path to the driver file.
HTH,
Hari.

PS: Sorry for my english.

Yes, the Oracle driver jar/zip file has to be in the classpath of the webapp or the server.
For webapp, drop the jar file in the webapp's WEB-INF/lib.
For server, add it to server-classpath or drop it in <instance-dir>/lib

Load oracle driver

Hello;
i got a problem to load the orocle driver, could anyone tell how to do that, thanks.
The oracle driver is sit in "C:\apps\Oracle".
when I run my code, then it tell me that Could not load the oracle driver.
The following is my code for load the driver.
//try to load the driver
        try {
            Class.forName("C:apps.oracle.jdbc.driver.OracleDriver");
        catch (ClassNotFoundException e) {
            System.out.println( "Cannot load the Oracle driver. Include it in your classpath.");
            System.exit( -1);
    }

You are confusing class name with class path.
The class is inside the driver jar. The driver jar needs to be in the classpath available to the application when it runs.
Class.forName() will load the named class.
In other words, you need to make sure your classpath is properly set (outside of Java), and the Class.forName() line should be exactly this:
Class.forName("oracle.jdbc.driver.OracleDriver");

Classpath problem instatiating oracle driver

Hi everybody,
I have made a little desktop application that fetches sum data in a oracle database and processes it. The program runs fine when I run it from my IDE. I have downloaded the oracle driver classes ojdbc14.jar . My problem is that I cant seem to set the classpath correct when running the application from commandline.
I use the command:
java -classpath .:ojdbc14.jar:jdom.jar QueryBox
where jdom.jar is for postprocessing the data i fetch out, and QueryBox is the GUI that starts the application.
The program is started correctly but when I come down to this part in the code:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());Then an execption occurs because for some reason it cannot find the OracleDriver class when im runnin from commandline. Any help wud be much appreciated!

Don't register the driver that way - just do this:
Class.forName("oracle.jdbc.driver.OracleDriver");That registers the driver class. - MOD

Can't load oracle driver...

h
i'm trying to connect to my oracle db from my jbuilder application and get the following error...
jdbc:oracle:thin@devserver05:1521:xxx_xxx
error loading class.forname

this is created from my code...

System.out.println(URL);
System.out.println("error loading class.forname");
e1.printStackTrace();
Connection con = DriverManager.getConnection(URL, userID, password);
return con;
}

and when i type the following into the command
line...
C:\jtm>java oracle.jdbc.driver.OracleDriver
i get the following so i guess my path is ok.....
Exception in thread "main"
java.lang.NoClassDefFoundError:
oracle/jdbc/driver/OracleDriverHi ,
try adding the import statement for the oracle driver, which is
import oracle.jdbc.driver.*;
and don't forget to add your oracle driver in the classpath..
hope this helps..

Problem with Oracle Drive Advanced Properties

I was able to successfully set up Oracle Drive however I cant use any of the advance features such as set properties and change access control lists. When I right click on a file I get an option for Advanced Properties but when I click on that selection I receive a message Advanced Properties is not supported by this server. This would be a big help to many of our users so any troubleshooting tips would be much appreciated.

We are using Portal version 10.1.2. We were able to get the options when we signed in a as the Oracle Admin but we dont want the users to have that kind of access.

Problem loading jdbc driver in Tomcat

Hi,
I have got a connection to MySQL5.0 from TomCat 5.5.13, that was test correctly in development (JSC Upd 1) but I encounter the following deployment error :
com.sun.rave.web.ui.appbase.ApplicationException: org.apache.jasper.JasperException: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot load JDBC driver class 'com.mysql.jdbc.Driver'
When I verify, I found that if I put the mysql Connector JDBC driver in <tomcat>/common/lib, there is no error.
But when the MySql Connector JDBC driver resides in <tomcat>/shared/lib, the error persists.
What's the difference ? shouldn't it work for both ?
Thanks in advance for any pointers and advise.

hmm... i guess that it's a must to include the lib at /common/lib instead of shared/lib .
Is there a Tomcat resource that I can read up on ?

Problem loading interclient Driver

Hello,
I have a problem with connection to interbase using jdbc :
I try to do like this :
try{
class.forname("interbase.interclient.Driver");
}catch (ClassNotFoundException e){System.out.println(e.getMessage());}
but allways the compilator show error message...
I Know I have installed InterClient on my windows machine and the CLASSPATH cotain the path of the "interclient.jar"...
also I tested the command : "java interbase.interclient.utils.CommDiag" and it show me the following message :

InterClient compatible IB versions: 5, 6
InterClient driver name: interbase.interclient.Driver

I hope that anyone can help me :-(
thanks

try{
class.forname("interbase.interclient.Driver");
}catch (ClassNotFoundException
e){System.out.println(e.getMessage());}Is this piece of code exactly the way you have written? The I think you have a problem of case-sensitivity. Your code should be:
try { Class.forName("interbase.interclient.Driver");
} catch(ClassNotFoundException e) {e.getMessage(); }Check this!

Problem with path length when using oracle drive

Hello!
Does anybody else experience this problem with Oracle Drive?
When I create a deep or nested hierarchy in which the path length is longer than 250 (the limit might be 255) characters, I cannot access the deeper subpages.
Example:"X:\INET\START1\pfadlaengentest\das istein langer ordnername mit etwa 50 zeichen\and this is another veryveryvery long\and this is another veryveryvery lon2\and this is another veryveryvery lon3\and this is another veryveryvery lon4\and this is another veryveryvery lon5".
I can access the page "and this is another veryveryvery lon4" but not "and this is another veryveryvery lon5"
Is this problem due to WebDAV?
What can I do - I think it is a critical error / bug?
Regards Joerg.

I opened a service request and oracle support could help me.
The problem is the windows file system: the path length cannot be longer than 256 chars.
There's a workaround with MS-Webfolders.
More information is available via metalink: watch out for SR-Number 5659267.992.
PS: Thanks to Bert

Oracle Drive Problem

I am having a strange problem with Oracle Drive (v10.2.0.0.5 WinXP)
I am connecting to Portal on AS10g R2 10.1.2 SEOne (SLES 9.3)
http://myportal.com:7779/dav_portal/portal
The installation went smoothly, and I can connect to the portal, login, and see the folders, but there are no files inside (I tried logging in both as a user with priviliges to manage content and as orcladmin).
When trying to copy items to the folders, only the folders are copied, and not the files inside them. I get the following error for each file:
There was a problem saving filename.pdf. Error 5, Access is denied.
Subsequently, I can see the folders in the portal (with no files, of course). What is going on? Why is it saving the folders but not the files?
Thanks,
DC

One more thing. I did find an FAQ doc for Oracle Drive, and it describes this error, but the suggested workaround did not fix it for me.
http://www.oracle.com/technology/products/cs/user_info/ocontent_services/drive_index.html#015010
FAQ ID: 015010
Updated: 2006-08-14
Version: 10.1.1, 10.1.2, 10.2
When viewing a list of files in a folder, a message says "There was a problem saving filename. Error 5, access denied."
You may see this error message if you are viewing a list of files in a folder to which you only have read access. To prevent this error message from appearing, set your Windows Explorer windows to open in List view or Details view.
