Andrew,
Thanks for the lightning response... but the problem has been solved.
I rebooted again, and installed again (didn't download again because the filesize checked out) and now it works fine, and I'm none the wiser as to the root cause of the problem, except that rt.jar has magically appeared:

Problem in running a class inside java_home/jre/lib/ext

I have a class file.
I compiled the class and packaged it to a jar file .
Then i place the jar file at java-home/jre/lib/ext
Now when i try to run this file it shows a NoClassDefFoundError
Do i need to set the path in some .properties files.???
please help me out....

i think its to do with setting the
java.ext.dirs path
if i compile it with like
java -Djava.ext.dirs=D:\jdk\jre\lib\ext Testthen it works and shows the Classloader as "ExtClassLoader"
But this is a run time setting.
How can i set this property "java.ext.dirs" permanently.

what is the purpose of alt-rt.jar in jdk1.6.0_20/jre/lib -- 64bit
thanks

Could this be because of one of these bugs:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6953058
or
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6959816
Actually the flags from the later bug are not set in our JVM but the crash happened between half an hour or several hours (I expect it was depending on the system load).

Mysql-connector-java

Hello with all
I have only one question, how to install mysql-connector-java under the archlinux, because I have to seek, is I do not have to find, it is for me to make a test with opencms, I seek a howto more precisely,
thank you
MM:/

regarde sur le site d'openSI, c'est un logiciel de compta open source et il utilise ce connector.
a l'époque j'avais éssayé mais leur application ne semblait pas en vouloir..
dans l'idée c'est un copier/coller et une modif dans httpd.conf, un fichier workers.xx aussi a creer.
peut etre que sur les sites mysql et apache tu trouveras de l'aide.

Fat Jar Export: Could not find class-path entry for 'C:Java/jdk/mysql-connector-java-

ok friends,
have a normaly running project in eclipse and want to create a jar file...i tried ewerythin in ->export but nothing function
i wanted to create a runnable jar file but that error ecures:
JAR export finished with warnings. See details for additional information.
Exported with compile warnings: ICQJJ/src/ICQJJ.java
Jar export finished with problems. See details for additional infos.
Fat Jar Export: Could not find class-path entry for 'C:Java/jdk/mysql-connector-java-5.1.8-bin.jar'
what's the problem?
ok, i am using a mysql db und using the driver mysql-connector-java-5.1.8-bin.jar....
i improted this jar file like this run -> run configuration -> classpath -> add external jar....
pls help me

That looks like it might be a binary-distribution JAR that you should unjar. The actual JAR for the classpath is probably inside it.

JDBC MySQL connector & autoexec.bat

This what I entered into my autoexec file but when I run my java program it gives me a 'no suitable driver' error. I do not know what I should be entering for the
'CLASSPATH' in the autoexec. Below is what I entered. The file jar file is located in my C:\unzipped\mysql-connector-java-3.1.7/ folder.
C:\unzipped\mysql-connector-java-3.1.7\mysql-connector-java-3.1.7-bin.jar%CLASSPATH%
Can somebody with knowledge in installing the JDBC driver for MySQL give me some help please.

This works perfectly in the Eclipse IDE area that I have but when I run the same program on the Net Beans 3.6 IDE area it gives me a 'not suitable driver' error. To note these are both on the same computer. I would really like to get the Net Beans 3.6 IDE working because that is what I am most familiar with using. If you know of the problem why one IDE area recognizes the driver where the next does not I would sure like to know. Somebody passed the idea that when the 3.6 area is executed there are multiple instances running and it resets the ClassPath(I think they where shooting in the dark but it is a lead none the less). Anyway if anybody has had this problem please enlighten me, Thank-You.
The ClassPath is set to the following:
ClassPath = C:\Program Files\Java\jdk1.5.0_02\lib;C:\unzipped\mysql-connector- java-3.1.7\mysql-connector-java-3.1.7;C:\Program Files
\Java\jdk1.5.0_02\jre\lib\ext;
This is the code:
import java.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class Connect2 {
     public static void main(String[] args) {
          try {

Need help with mysql-connector-j setup!

I have downloaded and installed Tomcat 5.5 and MySQL Server 5.0 and have both up and running. I then downloaded the MySQL-Connector-J and the folder is located at:
C:\Program Files\Java\jre1.5.0_06\lib\ext\mysql-connector-java-3.1.12
My JSP code looks like this:
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>
<%@ page import="java.net.*" %>
<%@ page import="java.util.*" %>
<%@ page import="java.io.*" %>
<%@ page import="java.sql.*" %>
<%
     try{
     Class.forName("com.mysql.jdbc.Driver").newInstance();
     catch (Exception E) {
     out.println("Unable to load driver. " + E);
%>And I am getting the folowing error:
java.lang.ClassNotFoundException: com.mysql.jdbc.DriverNow, before anyone tells me to go read other posts, I have already done this and I have tried changing my classpath with no luck. I have tried these locations as my classpath:
C:\Program Files\Java\jre1.5.0_06\lib\ext\mysql-connector-java-3.1.12
C:\Program Files\Java\jre1.5.0_06\lib\ext\mysql-connector-java-3.1.12\mysql-connector-java-3.1.12-bin.jar
Neither of which seem to work. Can anyone figure out what's happening here?

Ok, I copied it to the <tomcat dir>/common/lib, but I copied the entire folder (which I'm assuming is necessary), with no luck. So, now the location is:
C:\Program Files\Apache Software Foundation\Tomcat 5.5\common\lib\mysql-connector-java-3.1.12\mysql-connector-java-3.1.12-bin.jar
Any other suggestions?
Thanks.

Linux JRE and /lib/ext directory

I know this topic is fairly well discussed, but after reading many, many forum posts I have not found an answer. I've tried JRE 1.3.1_03 as well as a completely different JRE, from Blackdown.
If I run java from /jre/bin, on Linux, how does java know where the /lib/ext directory is?
Do I have to have an environment setup, such as java_home or should it find it by relative paths?
What environment variables must be setup for the JRE to operate correctly on Linux(in this case Redhat 7.2)
I have an application and the vendor just says to put these jar's in ext and the JRE will find them. Unfortunately, the JRE does not find them. I just want to make sure my environment is setup correctly.
Thanks,
James

I'll assume the wording of your response was not meant to be arrogant. lib/etx IS relative and the jars are NOT being found. I'm trying to figure out why.
It looks as though java's bin directory is in your path. Did you have to set that up or did the install set it up for you?
Again, what environment variables on Linux should be setup for the JRE to work properly? Any?
If I run something from the jre/bin directory, like: ./java TestClass, should the runtime be able to find jar's in the jre/lib/ext directory just by relative paths?
Thanks,
James

MySQL and Java - getting program to work

This is what I did.
I created a folder on my C: drive named MySQL.
I downloaded these two zip files form the MySQL website
     * mysql-connector-java-3.0.11-stable
     * mysql-4.0.18-win.zip
Installed both of these in folder MySQL.
I modified this line in the program ("ExecuteSQL" 1st pgm in chapter 17) I got from "Java Examples In a Nutshell" and compiled it into directory jwork.
String driver = "com.mysql.jdbc.driver", url = "jdbc:mysql://", user = "", password = "";
The readme file talks about putting a jar file in $JAVA_HOME/jre/lib/ext.
the word "Java_Home" (I now know) is not literally the name but represents the
name of the folder where the JDK to be used exists. So I put a copy of
mysql-connector-java-3.0.11-stable-bin.jar in folder C:\JDK14/jre/lib/ext.
Then I get a ClassNotFoundException error com.mysql.jdbc.driver.
After finding
http://forum.java.sun.com/thread.jsp?forum=31&thread=439796
and
http://forum.java.sun.com/thread.jsp?forum=31&thread=499888
and others, I copied (a second copy) the jar file to the directory where I am create my java objects.
Then I unzipped it to that directory, creating three folders that hold the unzipped objects.
I tried executing the program again. I get the messages at the top of this post.
The Manifest file is in one of the three folders unzipped to my java work directory.
In the second of the two above threads, jsalonen says:
the problem can be solved by mentioning mysql.jar in the Class-Path attribute
in the manifest of the jar file:
In this "manifest" file, there are only three lines and I added a fourth and it looks like this
(there are two, one in directory MySQL\META-INF and one in directory jwork\META-INF:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.1
Created-By: 1.4.0_01-b03 (Sun Microsystems Inc.)
Main-Class:jwork\ExecuteSQL
How do I "mention" mysql.jar in the class path attribute?
In the index.list file (in the directory with the manifest file, do I need to add anything to refer that "com.mysql.jdbc.driver" is the driver?
Do I need index.list in MySQL\META-INF ?

Don't put those JARs in the lib/ext directory. Only language extensions (e.g., packages that start with "javax") belong in there.
Learn how to set the CLASSPATH properly for starters:
http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/classpath.html
You might want to look at the JDBC tutorial, too:
http://java.sun.com/docs/books/tutorial/jdbc/
Do one thing at a time. Get the program to work, then worry about packaging it into an executable JAR.

Hi,
can you do me a favor got the following exception when I run the below code in the JBuilder4.
java.lang.NoClassDefFoundError: java/sql/Savepoint

Hi Vito,
This issue looks similar to the following thread I believe the problem was with the SAPJSF user

Java Mysql Connector

Hi everyone,
I started to work on JDBC but i have a few questions about the mysql connector.
I downloaded the .zip file and unzipped it to my desktop. Now i have a .jar file , a few folders , a installation guide and a read me file. But i couldn't understand the exact installation.
First of all where do i have to place this files? In which directory? I have a mysql database installed. But only the guide say is "calling the class.forname() function!"
I have no idea , what to place inside the forname function and where to install the connector files!
If u could tell me step by step i'll be really appreciate. Thanks for your helps.
Waiting for your answers :)

Let's see...
C:\Java\AppServer\jdk\bin\javac.exe is "javac
1.5.0_06"
.... That's the complete Java EE 5 SDKNo, javac.exe is part of Java SE. You have to have it for Java EE, of course. This version should match that of java.exe. Why does it not?
C:\Java\bin\java.exe is java version "1.5.0_08"How is it that the versions of javac.exe and java.exe don't match? You're making a mess here.
c:\MySQL50\bin\mysqld.exe is Ver 5.0.22-community
for Win32 on ia32 (MySQL Community Edition (GPL))Very good. Can you connect to MySQL using its client?
I've got copies of mysql-connector-java-5.0.3-bin.jar
all over the shop including:This is wrong. Don't have them "all over the shop".
C:\Java\lib\mysql-connector-java-3.1.13Wrong. Remove it.
C:\Program Files\Java\jre1.5.0_08\lib\ext //how the
flock did that get there?Didn't you say that you put it there? Wrong. Remove it.
C:\Program Files\Apache\Tomcat5.5\common\libCorrect. Leave it there.
C:\Program Files\Apache\Tomcat5.5\shared\libWrong. Remove it.
C:\Program
Files\Apache\Tomcat5.5\webapps\krc\WEB-INF\libPossibly wrong. Remove it.
You should have that JAR in one place from the point of view of your web context.
My system settings look like thisMicrosoft

.jarTomcat ignores that CLASSPATH. It does you no good at all. I don't have a system CLASSPATH on any machine I use.
C:\Documents and Settings\Keith>echo %CATALINA_HOME%
C:\Program Files\Apache\Tomcat5.5Fine. Might be good to put in in quotes, because that space between Program and Files might be problematic. Save for all other paths with spaces in them.
C:\Documents and Settings\Keith>echo %JAVA_HOME%
C:\Java\AppServer\jdk
Notice that Connector/J is not in my class
path.Notice that Tomcat doesn't care.
my code is the same as yours above except for
formatting, better exception messages, and the
username and password are different, which are case
sensitive BTW.import java.sql.*;
public class Connector {
     public static void main (String[] args) {
          Connection conn = null;
          try {
               String userName = "keith";
               String password = "**********";
               String url = "jdbc:mysql://localhost/test";
Class.forName
ame ("com.mysql.jdbc.Driver").newInstance ();
conn = DriverManager.getConnection (url, userName,
me, password);
System.out.println ("Database connection
ion established");
          } catch (Exception e) {
               System.err.println ("getConnection: " + e);
          } finally {
               if (conn != null) {
                    try {
                         conn.close ();
System.out.println ("Database connection
ction terminated");
                    } catch (Exception e) {
                         /* ignore close errors */
}hope this helps... Keith.
corlettk: oh yeah.. and mysqld is installed as a
service, which is running. tomcat isn't running, it's
not required for this test.If you run this test on the command line, you'd better be using the -classpath option to tell the JVM where to find the MySQL connector JAR. The JVM ignores your system CLASSPATH, too.
