Unable to load Driver Class

Hi There:
When I try to connect to the Oracle 8i via this applet , I get the following run time error.
Any help will be appreciated.
I am using j2sdkee1.3.1, jdk1.3.1_02 and Oracle8.
I also need your suggestion please. I have inserted some BLOB data in the Oracle table. I will need to display the BLOB data to the end users. I plan to convert this BLOB data into string format so that my applet can display the same. Further the string will have to be edited by the end users. I will then convert this modified string back to byte array so that I can insert the same as BLOB.
Please let me know applet or the servlet? Which is better option.
Users are reluctant to use any kind of WebServer because it will introduce the additional layer of complexity.
Any help will be greatly appreciated.
Thanks in advance.

Hi,
maybe I'm too late but try the following :
It seems that Your IDE doesn't check the path to Your classesxxx.zip file.
Or Your classesxxx.zip file is corrupt.
We had this error after downloading the classes12.zip for Oracle versions
higher 8.1.6.
The original size of this file is 1.888kB.
Remember Windows FTP is downloading in ascii mode per default.
Or Your classpath isn't correct
( the Exception souns like this )

Driver Class name and JDBC URL Format

Hi,
I'm trying to use the oracle jdbc driver to connect to an (what a surprise) oracle database.
I need a 'driver class name' and the JDBC URL Format. But I cannot find these anywhere.
Can anyone help me out here?

How can I access the oracle/sql server jdbc driver class files from my cust

I have a war file in which I have custom DataSource i.e mypackage.Datasource class. Its basically the need of my application. In this class we connect to datasource and link some of our programming artifacts .
I have deployed the oracle jdbc driver and deploy my application as ear with datasources.xml in the meta inf file. Inspite of that my code fails to load the jdbc driver classes.
Here is the extract of the code :
        Class.forName("oracle.jdbc.OracleDriver").newInstance();
         String url = "jdbc:oracle:thin:@dataserver:1521:orcl";
        Connection conn = DriverManager.getConnection(url, "weblims3", "labware");
        if(conn != null){
          out.println("the connection to the database have been achieved");
        out.println("conn object achived= " + conn);
Class.forname fails in this case. I can see the ojdbc5.jar the driver jar in usr\sap\CE1\J00\j2ee\cluster\bin\ext\ojdbc5 . I even put the ojdbc.jar in web-inf/lib and application lib but does not help at all. Hope I have explained my problem clearly.
I deployed the jdbc driver in the name of ojdbc5 .
I am stuck here. It will be great help if anyone can help me in this. Thanks in advance.

Bent,
You can access the database from your Java portlet, just like from any other Java/JSP environment. Yes, you can use JDBC, as well as BC4J.
The Discussion Forum portlet was built using BC4J, take a look at it's source to see how it was done.
Also, check out Re: BC4J Java portlet anyone?, it contains a lot of useful information too.

SOA WebLogic : Cannot load JDBC driver class

Hi, I'm new to this Oracle SOA World. Currently I'm trying to configure environment on my system. I found a very useful document to install all related SOA component to my system, the document name was 'Quick Start Guide for Oracle® SOA Suite 11gR1 (11.1.1.5.0)'. I did all the steps written in the document and have installed all the components successfully, component including Database, Jdevelper, WebLogic Server, RCU, SOA suite, service bus, all are installed successfully.
But when I'm trying to Configure Application Server (start -> Oracle SOA 11g-Home1), at one step 'Configure JDBC Component Schema' , here I'm getting this message
* The driver class listed below was not found in product installation
vendor: Derby

A Test will not be performed on any database connections using this driver
In addition, when i just ignore this message and continue installation, after installation when i run weblogic server then it gives error and gets terminated

Hi:
try placing the jars that represent ur driver, here
For both Windows and Linux, you must perform the following steps:
Drop the vendor-specific driver JAR files to the user_projects/domains/soainfra/lib directory.
Drop the vendor-specific driver JAR files to the <Weblogic_Home>/server/lib.
Edit the classpath to include the vendor-specific jar file in <Weblogic_HOME>/common/bin/commEnv.sh
This info was copied, from here: http://docs.oracle.com/cd/E21764_01/integration.1111/e10231/adptr_db.htm#CHDBEJDC
Hope this helps

Post the part of your code that loads the driver and connects. My guess is you are using a variable for the name of the driver and the variable has not been set to anything(intially set to null).

JDBC Driver Class for DB2 databases on OS/390

Hi,
To anybody who can help.
I am trying to connect to DB2 database on OS/390 from my PC - Windows 2000. I have loaded IBM DB2 Application Development Client V7.2 as well as IBM DB2 Administration Client V7.2 I guess this is called using Db2 Connect. I have done proper configuration of host databases.
Anyway, I write this small simple class to connect to Db2 database and I keep getting this error.

Any help on this will let me move further in my project. ThankYou.

Nice trap from IBM: package name starts with COM not
com!
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");---Sure I tried that. Sorry. That doesn't work.
I tried with Class.forName("COM.ibm.db2.jdbc.net.DB2Driver");
That doesn't work either.
Is my connection URL OK? I made several kinds of format changes to the URL
"jdbc:db2://db2test.state.sc.us:50000/DB2DB02";
"jdbc:db2:db2test.state.sc.us:50000:DB2DB02";
etc....For now I am sticking with the first version.
Any more suggestions please. Did you take a look at my classpath. Is that OK? Should I rename db2java.zip to .jar and are there any other dir's where it should be contained?????
ThankYou all.

Exception Description: Unable to process XML tag [driver-class] with value

Hi
I'm newbie with TopLink. I try to write a litle application with TopLink:
- First, I create a session.xml file:

- Second, I create a Java Application ( Application1.java):
package project2;

public class Application1 {
public Application1() {
public static void main(String[] args) {

String statement = "SELECT motdepasse,login FROM bou_courtier";
SessionManager sessionmanager = SessionManager.getManager();
System.out.println("test");
// SessionFactory sessionfactory = new SessionFactory("META-INF/sessions.xml","dbsession");
DatabaseSession session = (DatabaseSession)sessionmanager.getSession(new XMLSessionConfigLoader(),"dbsession",Thread.currentThread().getContextClassLoader());
// Session session = sessionfactory.acquireSession();
System.out.println("test");
SQLCall sqlcall = new SQLCall(statement);
session.executeNonSelectingCall(sqlcall);
ResultSet rs = sqlcall.getResult();
try {
while(rs.next()){
String strPass = rs.getString(1);
String strLogin = rs.getString(2);
System.out.println("Password :"+strPass+"---"+"Login :"+strLogin);
} catch (SQLException e) {
// TODO
- Third, I build and run Application1.java in Jdevelopper 11g preview 3. Sadly, the result is a error:

The internal error: "java.lang.ClassNotFoundException: oracle.jdbc.OracleDriver"
is stating it can't find your driver jar file on the classpath. You'll need to check that you've included your Database driver in the list of libraries on your classpath.
Best Regards,
Chris

Cannot load JDBC driver class 'com.mysql.jdbc.Driver'

Hi,
At the moment I'm trying to get an example working. The error message I get is:
Unable to get connection, DataSource invalid: "org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot load JDBC driver class 'com.mysql.jdbc.Driver'"
The example I tried is http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html.
Configuration:
Wampserver 2.0 (Apache, MySQL, PHP for Windows XP), Tomcat 6.0 and jdk1.6.0_03.
The following files are installed in %CATALINA_HOME%/webabbs/
- Dbtest/test.jsp
- Dbtest/WEB-INF/web.xml
- Dbtest/WEB-INF/lib/standard.jar
- Dbtest/WEB-INF/lib/tomcat-dbcp.jar
- Dbtest/WEB-INF/lib/jstl.jar
Tia,
Abel.

Hi,
I added the jar file containing the requested class to my lib directory. So the current contents of that directory is:
The following files are installed in %CATALINA_HOME%/webabbs/
- Dbtest/test.jsp
- Dbtest/WEB-INF/web.xml
- Dbtest/WEB-INF/lib/standard.jar
- Dbtest/WEB-INF/lib/tomcat-dbcp.jar
- Dbtest/WEB-INF/lib/jstl.jar
- Dbtest/WEB-INF/lib/mysql-connector-java-5.1.5-bin.jar
More importantly, I started my Wamp server.
The example works as it should have. Thanks for the feedback.

Application that handles multiple jdbc drivers. How to load driver classes?

Hi all,
I have a question that arised now while I am developing an application that handles different jdbc drivers.
Do I have to reload the driver class when I want to use a different jdbc driver?
Does DriverMAnager return connection of the last loaded jdbc driver?
thank you in advance, Kostas

No.
No.
Read the docs:
http://java.sun.com/j2se/1.4.2/docs/api/java/sql/DriverManager.html
which says in part:
"When the method getConnection is called, the DriverManager will attempt to locate a suitable driver from amongst those loaded at initialization and those loaded explicitly using the same classloader as the current applet or application."
In other words, getConnection inspects the provided database URL and tries to find a driver that can handle the URL.
I've had no problems with a program that uses bothe Oracle and MySQL at the same time, alternately reading from one and writing to the other.

Java database connection method class for review

Can you guys tell me any specific coding standard has to be followed here(i guess i need not hard code the pwd's)
import java.sql.*;
public class DBLocator {
     * Obtains and returns a connection to database
     * @return database connection
     public static Connection getConnection() {
     Connection con = null;
     try {
          Class.forName("com.informix.jdbc.IfxDriver");
          String url = "jdbc:informix-sqli://151.140.160.201:1527/ssde_db:INFORMIXSERVER=ssde_infx";
     con = DriverManager.getConnection(url,"haha06","123123");
} catch (ClassNotFoundException e) {
               System.out.println("Driver not found");
          } catch (SQLException e) {
               System.out.println("SQL exception");
               e.printStackTrace();
          return con; // returns connection
}

Can you guys tell me any specific coding standard has
to be followed here(i guess i need not hard code the
pwd's)More than just the passwords. Why are the driver class and URL hard-coded?
I wouldn't use this class. It's not very useful as written. It's a poor abstraction for one. There's lots of other useful things that you could include, like methods for closing and rolling back a connection, closing a statement and result set. You don't log any exceptions or messages. You preclude the use of a connection pool managed by an Java EE app server.

Data Modeler 3.3EA2 Driver Class Not Found

When trying to connect to a SQL Server 2008R2 instance I get teh message "Status : Failure -Test failed: Driver class not found. Verify the Driver location"
I have added the SQL Server JDBC Drivers to my PATH environmental variable, and even tried to put the JDBC driver into a folder without any white spaces in the directory name
C:\Progra~1\Microsoft JDBC Driver 4.0 for SQL Server\sqljdbc_4.0\enu\sqljdbc4.jar;C:\Progra~1\Microsoft JDBC Driver 4.0 for SQL Server\sqljdbc_4.0\enu\sqljdbc.jar;C:\Temp\sqljdbc4.jar
I also added the sqljdbc4.jar to the Data Modeler: Third Party JDBC Drivers screen.
Any thoughts on what can be causing this issue?

I was unable to get the JDBC ThirdParty Driver to work, since no matter what I did I could not get the Oracle Data Modeler to map to the JDBC jar file. Here is a work around...
Steps to connect Data Modeler to a SQL Server database.
On Windows 7
1. Go to Adminstrative tools -> Data Sources (ODBC)
2. Select System DSN and setup a connection to your SQL Server database
3. In Data Modeler click File -> Import to bring up the Database connection string
4. Click on the JDBC tab
5. For the OCDBC alias use the connection name you created in step #2
If anyone else is able to get the JDBC ThirdParty driver to work will you please post it here.
