Can't found Driver class, but CLASSPATH is set!!!

I know this must be a favorite, but I have searched for 2 hours and can't found a solution for my problem. when I call Class.forName("com.mysql.jdbc.Driver").newInstance(); it throws the following exception: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver.
I have set the CLASSPATH and in Netbeans I have the Driver in fact I can connect to the Database in the Services tag, but I can't connect to it when I run the application.
I have connector/j version 5.1.6
Java Version 1.6.0_03
LinuxMint.
Please help.

I have set the CLASSPATH Believe the class loader - it can't find it. That means you did it incorrectly.
If CLASSPATH is an environment variable for you, I can assure you that it's incorrect. All IDEs and app servers ignore any CLASSPATH environment variables. It's worthless. I don't have one on any machine I work on.
and in Netbeans I have the Driver in fact I can connect to the Database in the Services tag, but I can't connect to it when I run the application.Best to add those JARs to the CLASSPATH the way NetBeans uses it. It's got to have a way to add 3rd party JAR dependencies.

Content server can not load javax classes in classpath

I have added a jar including javax.* classes to classpath of content server.
I can see the jar in content sever configuration page of classpath.
But those javax.* class can not be loaded into content server.
Content server is throwing java.lang.ClassNotFoundException.

ITunes 11 adding songs to Library which don't show up but can be found by Searching - but can't be player

Hello,
I got a little problem here...
My iTunes 11 won't show the titles of a new album i tried to import!
I imported them the normal way, after this i recognized there was a problem, i had the album two times. I tried to fix it by changing the album name on every track again... It didn' work so I removed the tracks from my Library... then I wanted to reimport them, but... they just didn't come up...
I looked for them and found them in my Media folder. I deleted them there again and tried to import again... Nothing... they just won't appear in iTunes but are always present in the Media folder!
I can also search for the band in iTunes and can find it, but if i press play (also if the songs can be found in the Media folder) it won't do that... it just doesn't show them, i can't remove them from my Library and can't play them!
Does anyone have a solution for a problem like this?
Sorry If my english is bad at the moment, but i'm very tired and the day wasn't funny at all...

Please,please help, this drives me crazy,can not find the class but...

The story is:
I have alot java class files under directory: c:\myproj\com\pin\sa
in each of the file, the package signature is: package com.pin.sa
Then I set the JavaVMInitArgs fVM_args; by setting the classpath to:c:\myproj
then I use: cls = (*fEnv).FindClass("com/pin/sa/frameWork") to find a class file called frameWork, but failed.
then i build a test file called test.class (it is just a simple file pls see below for the code)and put package com.pin.sa in it and put it in directory : c:\myproj\com\pin\sa, this means the test.class is under the same directory as the frameWork.class,
then I use cls = (*fEnv).FindClass("com/pin/sa/test"), and it SUCCEEDED!!!
I really don't understand why like this, they have same package signature and under same directory why different results.
In frameWork file, there are some imported packages, does this matter? And there is a static main() in it.
if you can give an example of how to set the classpath in JavaVMInitArgs fVM_args, and how to deal with the package signature, I will appreciate it very much
==test.java==
package com.pin.sa;
public class test
public void printHello()
System.out.println("Hello World from Java!");
cls = (*fEnv).FindClass("com/pin/sa/test");
cls = (*fEnv).FindClass("com/pin/sa/test");
C:\\myProj\\resiprocate\\myAnalysis\\sipphone\\sipXphone\\main\\softphone\\lib");

Hi Hufuman,
What are the packages that you are using in frameWork Class. Add the class path to those classes also. Also check the name of the .class file is exactly the same as frameWork and not FrameWork or framework etc.
Check whether you have correctly given the package declaration in the frameWork class.
If you dont have any problem, post the frameWork class definition also here or atleast the packages imported and the classpath set for those referred packages.

Other thing that I don't know if is important for this is that I can't find the page using my IP or 127.0.0.1, it only works using localhost.
And yes, my jar is signed. In fact it works perfect on a non Windows-Vista machine, so I suppouse is something with the browser here or something like that. The port is on the exceptions list of the firewall but I've even disabled the firewall with no changes. I can load applets from other hosts, but I can't pointing to my machine, so I don't know if is windows, tomcat, or whatever. Please help!
I'm using Tomcat 5.5, JK 1.6 and Windows Vista as server. Using the 2000 port which is on the exceptions list in the firewall. I have also IIS7, but it gives no problems. I mean if I do http://myhost (port 80) the IIS7 initial page shows, but if I use http://myhost:2000 (which is the port configured in Tomcat) then can't find the page. I don't know if is something on the firewall, on the tomcat, or what ever.
Please help!

I've seen this sort of thing happen when the server is misconfigured and reports the content MIME type incorrectly.
I'd suggest using a tool like curl or the Firefox LiveHeaders extension, to confirm that that's correct.

Some contacts can be found by search but don't show in list view

A few of my contacts (some of them are favorites) don't show up in the list view in my address book just by looking alphabetically. I can search for them using spotlight or the search field at the top of the list and there they are. Why is that? Is it a bug?

Nah. None of those that I looked through on the first 8 pages or so BUT I checked Address Book on my computer and I have the same quantity of contacts listed on my computer as on the phone under "all groups." So, I went hunting around for the missing contacts and, although the last name starts with "Sw," they were listed at the top of all the "S" contacts. Why? Beats me. Makes NO sense at all. They are listed in proper order on my computer. They are marked as "favorite" contacts, but so are some of my other contacts and this behavior doesn't happen with those.

My JSP can't find a class file

Hi
I am trying to view a JSP but I get ClassNotFoundException. I know that it means that it can't find the class but I can't understand why.
my directory structure:
Intranet->source
->jsp
->WEB-INF->classes->source-><class file here>
first line of .java file:
package source;
JSP code:
<%@page import="java.sql.*, source.*, java.util.*;" %>
<jsp:useBean id="dbConnect" scope="session" class="source.DBConnect">
<jsp:getProperty name="dbConnect" property="jdbc:odbc:Auto_Intranet" />
</jsp:useBean>
Must I create an environment variable for 'Windows': with classpath " .....\WEB-INF\classes"
The Windows environment variable doesn't exist----using XP Pro

Looks right to me.
You don't need a classpath variable. Web containers ignore it anyway.
Which class is not found? source.DBConnect?
Is DBConnect in a package called source?
Is your database driver in the web-inf/lib directory?
Please post the full error message with stack trace - it will be easier to sort out.
Good luck,

Driver Classes

I am using BlueJ and I was wondering where the arrow points from the driver class.

but when I run the applection as desktop one it is work.Does it work when you don't provide a classpath and let the jre find the needed files in ext?
If you have a jdk installed there is a jre in jdl/jre and jre (under program files).
How can I make the applet connect to the database in good way from the web like Oracle wise?Use a web server with (for example servlets) to get data from the database.
Applets run on the client and besides not finding the needed classes you get
problems with sandbox security, users decompiling your applet and knowing how
to connect to your database and cached versions of your applet failing or
inserting corrupt data when you changed your logic.

I just sold my iPhone 4s after doing a reset and deleting data and settings. Is there anyway the buyer can see any of my old photos, texts, or data? I have confidential info for work and family photos and freaked out that they can be found somehow.

No, but if the answer was yes it's a little late to start getting freaked out about it.

Why we can't instantiated System class.

Hi All,
I can't undersatnd what type of class is "System". We can't instantiated system class but we can use it like a Static class.

There are number of classes like that. You don't
instantiate them because you don't need to.Objects
have state and behavior. State is captured inmember
variables. None of the functionality the Systemclass
provides requires an object to be instantiated and
maintain state in member variables. It's pure
behavior.I beg to differ. Given he fact that it has attributes
(e.g. in, out and err), it does have a state...They're static attributes, so no instance (if one existed) would have its own state that would potentially distinguish it from other instances. That's what I was talking about.
I, personally, think that static classes are rather
bad OO (it's objects doing the work, not classes),
but singletons are too burdensome to create.You mean uninstantiable classes with only static methods? (System is not a static class. Only nested classes can be static.)
If your goal is to write pure OO, then, yeah, they might be bad. But then I don't think "perfect OO" is a particularly important or useful goal. Tool for the job and all that.

I can introspect a db successfully, but at RT the driver cannot be found?

Not sure what to do here - I have the ms db driver sqljdbc-2.5.jar added as an external resource, I have it in umpteen lib directories under my studio directory and at runtime the albpm engine still cannot find it, even though design time introspection works perfectly. Any ideas what is going wrong? I am running the dev engine within studio on my localhost.
Output on startup of engine:
Cannot initialize External Resource [IdSeqTracker:SQL:MSSQL2005].
Detail:An exception has occurred while initializing external resource [IdSeqTracker:SQL:MSSQL2005].
This external resource will not be available until the problem is fixed.
The server will start normally but any execution that attempts to access this resource will fail.
This only affects code execution, not the base server functionality.
Caused by: The JDBC driver library files for the connector were not found.
Detail:Connector [IdSeqTracker:SQL:MSSQL2005] caused an exception when initializing.
The driver class [com.microsoft.sqlserver.jdbc.SQLServerDriver] was not found.
Verify that the JDBC driver libraries are defined as external resources in the environment.

did that, and also under studio/lib, studio/library, to no avail.
Got round it by doing the jdbc stuff manually in a java activity. Obviously there's a bug somewhere.

JDBC driver - Class oracle.jdbc.driver.OracleDriver not found.

Greetings:
When I tried to compile an test script (as attached below) to test the driver, I always ended up with the following error message:
....java:17: Class oracle.jdbc.driver.OracleDriver not found.
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Could somebody shine some light on it? I would very much appreciate it.
By the way, I have an Oracle DBMS (8.1.7) with jre1.1.7. My Java is jdk1.2 and the driver is ocijdbc8.dll
Wil
*************** The test script *************

check out what thomas Fly wrote on another discussion forum about connection with JDBC, i tried it and i haven't gotten it
to work yet but at least i don't have the "... not found" error,
you should try it too, and i think it's good to tell you that i
still haven't installed the oracle client on my windows Me PC.
Hope this help you
This may help also... I have Oracle installed on a Linux PC at 192.168.1.4 on my LAN, listening on port 1521. I can connect from another PC (Linux / Windows ME dual boot, though running Windows at the time of this experiment) using the following program:
import java.sql.*;
public class sqlLookup {
public static void main(String[] args) throws SQLException, ClassNotFoundException {
String dbUrl = "jdbc:oracle:thin:@192.168.1.4:1521:ORA8";
String user = "thomasfly";
String password = "maverick";
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection c = DriverManager.getConnection(dbUrl, user, password);
Statement s = c.createStatement();
// SQL code:
ResultSet r = s.executeQuery("select * from members");
while(r.next()) {
// Capitalization doesn't matter:
System.out.println(r.getString("Name") + ", " + r.getString("id") + ": " + r.getString("email") );
s.close(); // Also closes ResultSet
I downloaded classes12.zip for Oracle 8.1.7 and put it into the C:\Windows directory, and mounted C:\Windows\classes12.zip in Forte for Java (equivalent to adding it to the classpath if I were running the program from a DOS window, rather than in Forte).
ORA8... capitalization may be important... is the name of my database, which may be found in the tnsnames.ora file in $ORACLE_HOME/resources.
The query gets the Name, id, and email fields from the table "members" in the database.
This is just a barebones program, and each time it's run, the Oracle listener has to be stopped and restarted before the program can be successfully run again.

Access of MySQlL Driver class by eclipse but not from Outside Jar file

Dear All,
I have done a standalone application having access with MySQl database.
I could access it when i execute it from eclipse. But when i export it into Jar file and running I get MySQL Driver class not found exception.
Give me a better solution for this issue.

CLASSPATH, CLASSPATH, CLASSPATH.
You have defined the Eclipses Project Library Path to include the MySQL jar, but ar not including it on the classpath when executing the jar.
Either modify the MANIFEST.mf file in the jar to include a reference to the MySQL driver jarfile or call java in the following manner
java -cp /full/path/to/MySQL/Driver/jarfile.jar -jar yourJarFile.jarObviously, if this is on Windows and you are executing through a double click, the first option is the best option.

I have seen this error when I'm executing inside one of the (j2ee sun reference implementation) server containers (either web or ejb). I believe its caused by "something" having previously loaded the "sax 1 driver class". In my case, I think the container or server is loading the sax parser from a jar that contains a sax 1 version. If you can, ensure that nothing is loading the sax 1 parser from another jar on your system. Verify that you are loading the sax parser from a jar containing the latest version so that you get the sax 2 compliant parser. Good luck!

I know that the jdbc driver is in the classpath, and to confirm that I have created a java program in the IB (repository) which import the class oracle.jdbc.driver.OracleDriver. I can compile and run that program without problems.
Here you can see my jdbc adapter configuration file:
jdbc adapter java class
classname=com.sap.aii.messaging.adapter.ModuleDB2XMB
mode=DB2XMB
Integration Engine address and document settings (example, see docu)
XMB.TargetURL=http://<host>:<port>/sap/xi/engine?type=entry
XMB.SenderBusinessSystem=ExtAdapterSender
XMB.SenderInterfaceNamespace=http://sap.com/xi/xidemo
XMB.SenderInterfaceName=ExtAdapterSenderIF
XMB.QualityOfService=EO
##DB Adapter specific parameters (example for SQL-Server, see docu)
db.jdbcDriver=oracle.jdbc.driver.OracleDriver
db.connectionURL=jdbc:oracle:<user>:<password>/hello@<url>:<port>:<instance>
db.processDBSQLStatement=Select * emp
db.pollInterval=600
xml.recordsetsPerMessage=1

Hi Ernesto,
Can you try to the following:
1. Remove your JDBC driver entries from the CLASSPATH.
2. Put those jars into your jre/lib/ext directory.
3. Restart the whole adapter engine, and
4. Config the driver java class for the adapter. the class name to be used can be found in your JDBC driver document.
Let me know whether it works.
Hart

Can't found Driver class, but CLASSPATH is set!!!
