Applet connecting to Mysql on serverside?problem

hi all
i am having some problem in Applet
The problem is i am drawing on an applet.
which is taking input from database(Mysql)
it is running fine on konsol in appletviewer,
but when i run in Browser(NetScape 4.*) it is giving error
Applet not started , code is as follows
/*<applet code="AppletSql" width=100 height=100></applet>*/
import java.sql.*;
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
import org.gjt.mm.mysql.Driver;
public class AppletSql extends Applet{
Exception e1;
Button b ;
public void init(){
try{
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
}catch(Exception e){}
b= new Button("Hi");
add(b);
i am using Tomcat as my server, now i am keeping my this applet in my /usr/local/jakarta..../weapps/examples/jsp .is it the problem of my server, do i have to configure my server for mysql-connector..
or is it like this as appets are running on client side,so u cannot
connect to Drivers on Server,or i have to write socket prog.. for
connecting to Applet can i do the same thing swings or beans,or can i draw graphics with beans
Thanking you
sunil

In your html page, you need to have the applet tag e.g
<applet code="classname" codebase="serverurl" height="" width="">
</applet>

Why JApplet and JSP cannot connect to MySQL

When i use applet connect to MySQL, it show that no suitable driver.
My program is

If I using JSP, it also have some condition

Clearly it is in the classpath, otherwise the error would have been "Class not found". But here's a quote from the documentation for the driver, the part that explains how to make a connection:// The newInstance() call is a work around for some
// broken Java implementations
Class.forName("org.gjt.mm.mysql.Driver").newInstance();The "broken Java implementations" it refers to are certain JVMs that run applets in browsers...

Problem connecting to MySQL thro Applet using JDBC

Hi,
I'm trying to use an applet to connect to MySQL thro JDBC. The applet, the IE client that loads the HTML, and MySQL all reside on the same machine. But I'm getting the following error:"ClassNotFoundException: com.mysql.jdbc.Driver". But I'm able to connect using a Java application and run and display SQL query results. Any ideas are highly appreciated. Here're are the two pieces of code:
/****** Java Application *****/
import java.sql.*;
public class MySQL_App {
public static void main(String args[]) {
          String url = "jdbc:mysql://localhost/test";
     try {
               Class.forName("com.mysql.jdbc.Driver");
     catch(java.lang.ClassNotFoundException e) {
               System.err.print("ClassNotFoundException: ");
               System.err.println(e.getMessage());
/****** Java Applet *****/

     catch(java.lang.ClassNotFoundException e) {
               args[0] += "ClassNotFoundException " + e.getMessage() ;
     win.call("showMessage", args);
}

mmm i, think that may here we've 2 possibles answers:
1) Did u read about "Applet Security"? my point is that you haven't acces to your local var "path" or "classpath".
2) Maybe u didn't especificate the MySQl path in ur classpath;
Check this 2 points

Connecting to MySQL from an Applet

Hi !
I have some serious Problem connecting from within my Applet to a MySQL-DB. Everything is fine until i try to establish a Connection ( I use mm.mysql-driver ). The Driver seems to be correctly loaded, but when it comes to connection I get the following Error : Connection failed, Are you sure, that there is a MySQL-Database running at the specified target bla bla bla .....
I guess, that it is some Problem with the Applet not beeing certified, but as it is only intended for INTRAnet use, I don't really care about security. Has anybody a quick workaroud for my Problem ?
Thanx in advance
Regards
Markward Schubert

i would try to connect to that database with application, if that fails as well then there is no applet certification problem
usually this kind of error is printed when you try to connect to some database that is not there
and with an applet you need to put applets binaries and database in the same server, because applet can connect only to the host where from it was loaded
i hope that some of it helped

Applet connection to remote MySql - HELP

Hi:
I've got an applet that connects to a MySql database (4.1).
As long as I try to connect to the MySql server on the machine the applet is running on (my development computer), everything works great.
I'm using this jar as the MySql connector:
mysql-connector-java-5.0.3-bin.jar
I can connect to the remote MySql server (also 4.1) with MySql Administrator and also with .NET, no problem.
BUT - when I try to connect to the remote MySql server from the Applet I get an 'access denied' error.
I also tried it from the applet set up as a Java application with a main function. If I try to connect to the local MySql server, no problem. If I try to connect to the remote machine I get a 'connection timeout' error.
I should add that when I connect to the remote machine from MySql Administrator, the connection is almost instantaneous and with no problem.
Any help would be greatly appreciated.

Well, I've been over it and over it. I've read and tried everything I could find.
No matter what I do it won't connect.
The applet is signed, I don't need to learn how to do that.
The popup comes up and asks if I want to run it: I click YES
The connection works fine for the local database but not the remote one.
Again, I can connect to the remote one with MySql Admin just fine using the same parameters.

Problem to connect to mysql from servlet using a javabean

Hi,
I'm new here and beginner on java to.
I have problem to connect to MySql database, by a connection javabean.
It's the following: a HTML page calls a servlet and this servlet imports the package connection javabean.
It has no problem when I establish the connection inside the servlet, with all its methods (public and private). But i want to separate the code connection from servlet.
Detail: there is no problem, using the javabean to connect to MS Access database.
I put "mysql-connector-java-3.1.12-bin.jar" file inside WEB-INF/lib application and common/lib directories.
I set the classpath:
SET CLASSPATH=%CATALINA_HOME%\COMMON\LIB\mysql-connector-java-3.1.12-bin.jar;%CLASSPATH%
I think that the servlet cannot create an instance of javabean, because passed by catch exception of the servlet init method.
But I don't know why.
Please Why?
Below there are the fragment of errors, servlet code e javabean code.
Thank you.

Read/Write problems with multiple connections using MySQL & Tomcat

hello all,
I am developing a web-based java application that runs on a 4.1 tomcat server and uses MySQL 3.23.52 as db server.
this program uses hundreds of tables with hundreds of rows each.
when two or more users are connected, we are experiencing several problems:
1. when a query is started, they get cross-results that come from both connections.
2. when inserting/updating (most queries are long and take a few seconds), sometimes data are crossed too, sometimes they are saved incorrectly but get no error message, sometimes they are not saved and get 'null pointer' sqlexception (but tables and queries are correct).
3. using SHOW PROCESSLIST and SHOW STATUS, we saw that MySQL server hosted no more than 3 max_used_connections, even when my.cnf parameters where set with more. when 3 or more users try to access the database, they get a bad handshake error until other connections are freed.
any suggestions?
thanks

I am not using a connection pool. I read that when two different connections try to access the same data simultaneously, mysql is not secure. maybe a connection pool could solve that? or maybe is it a mysql limit?

Problems with connecting to mySQL

Hi,
I'm using JSP for web development and I want to use mySQL as my database.
My problem is:
When trying to create a new instant
Class.forName("com.mysql.jdbc.Driver").newInstance();
I get the following exception:
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
Please note that I'm using NetBeans as my IDE. The IDE itself successfully connects to mySQL and gets the schema.
Anybody helps?

I get below error on excecuting the code.

Problems with connecting my Mysql db to visual studio 2013

Hey all,
I tried connecting my MYSQL db to my visual studio 2013
after installing all db connectors from MYSQL and tried following multiple guides its still not working.
I first had VS Express but it seems the express versions don't support that so then i went to get a VS Professional 2013 (trial i think) and this didn't work either.
Does anyone know any solution other than installing connectors (reinstalled them like 2 times already) or getting another VS ?
Thanks in advance

Hi Weffke,
The forum supports VS setup and installation. And I think your issue isn't related to the forum.
>>after installing all db connectors from MYSQL and tried following multiple guides its still not working.
I think your issue is more about MYSQL. So I suggest you post your issue to the related forum below.

Connection to MySQL via ODBC not working

Hello all together,
I've got a problem with the ODBC connection to MySQL. The connection via ODBC is established and things like tnsping are working.
When I select some data within the SQL*Plus environment, I get no real result. For example "select table_name from all_tables@mysql;" returns nothing.
My entry in listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME=odbc_mysql)
(ORACLE_HOME=D:\oracle\product\11.0.1\db_1)
(PROGRAM=dg4odbc)
My entry in tnsnames.ora:
MYSQL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA = (SID=odbc_mysql))
(HS=OK)
The initodbc_mysql.ora in ORACLE_HOME/hs/admin/:
HS_FDS_CONNECT_INFO = odbc_mysql
HS_AUTOREGISTER = TRUE
HS_DB_NAME = hsodbc
I tried some modifications but I still get no data from mysql database. When I try "select * from customer@mysql;" I get the correct number of records, the correct column names, but the content is always "¬¬¬¬". The odbc driver works, because with MS Access I can fetch the data. I'm using Oracle 11g Release 1 EE and MySQL ODBC 5.1.5.
What could be the reason for this?
Greetings,
Joerg

created in my UTF-8 Mysql DB your table and inserted a record; the select shows:
SQL> select * from "movieclass"@mysql;
idClass
ClassName
123
H e l l o
As you can see the content is there, the "space" between the letters is related to unicode. Each character is interpreted by 2 bytes and SQL*Plus wrongly displays both. Using iSQLPLus or SQLDeveloper does not show the "space" between the letters.
Here the data type mapping:
SQL> desc "movieclass"@mysql;
Name Null? Type
idClass NUMBER(3)
ClassName NOT NULL NVARCHAR2(50)
What's the exact version of DG4ODBC you're using? 11.1.0.7?
According to the listener file you're using DG4ODBC on Windows. There was a high/low byte issue in DG4ODBC for Windows. This issue is fixed in 11.1.0.7 and a certain patch. So I recommend you to get first the 11.1.0.7 patchset (if you don't already have it installed):
6890831 Oracle Database Family: Patchset

Can't connect PHP/MySQL 404 error

Wow, the learning curve is killing me. Yet another challenge. I'm using Dreamweaver CC and this tutorial http://www.adobe.com/devnet/dreamweaver/articles/setup_php.html
I'm at this step:
Open comments.php. You must have a PHP page open in the Document window to create a MySQL connection.
In the Databases panel (choose Window > Databases), click the Plus button on the panel and select MySQL Connection.The MySQL Connection dialog box appears.
Type connTest as the connection name.
For the MySQL Server, type localhost.If you are using the MAMP default ports on a Mac, use localhost:8889.
For the User Name, type phptestuser.
Type the password you chose for the phptestuser account in the Password field.
For the Database, type php_test.Note: You don't need to precede the underscore with a backslash here. It was inserted by phpMyAdmin in the previous section (see Figure 20) only because phpMyAdmin uses a query that permits wildcard characters.
Click Test.Dreamweaver attempts to connect to the database. If the connection fails, do the following:
Double-check the server name, user name, and password.
Check the settings for the folder Dreamweaver uses to process dynamic pages (see Specifying a Testing Server for Dreamweaver).
Verify that the web and MySQL servers are both running.
Temporarily disable any firewall or security program. If the connection works, you need to configure the security program to permit communication between Dreamweaver and MySQL.
Click OK. The new connection appears in the Databases panel.
Expand the connTest connection, and then expand the Tables branch. You'll see the comments table in the database, which you can expand to reveal the details of the table columns (see Figure 23).
As far as I can tell I have followed this tutorial to the letter.
As far as I can tell, XAMPP/php mySQL are all running fine, the files are in the correct place and everything should be working. However when I hit test I get a 404 error. (Same error when I hit the select button.)
The suggested problems on the 404 message are:
1. There is no testing server running on the server machine.
Pretty sure the testing server is running. Is there any way to test this, other than to note that xampp is definitely running right now and that I can log into phpMYadmin no problem?
2. The testing server specified for this site does not map to the http://localhost/php_test/_MMServerScripts/MMHTTPDB.php URL Verify that the URL Prefix maps to the root of the site.
Ummm...I'm pretty sure I put things where I was told to put them in the tutorial, but I'm lost at this point where I should verify what. A clue here? The files are where they are supposed to be, but maybe I entered something wrong? Except...I'm not sure what that could be or where to find it. Whatever IT is.
Everything in local files is looking good.
Thanks for your help!
PS: Extra points to anyone who figures out how to make copy/pasteable error messages! These buggers are the bane of my life!

Bgupta, you rock!
I hope you have copied the "mysql.php" and "MMHTTPDB.php" files from "C:\Users\username\AppData\Roaming\Adobe\Dreamweaver CC\locale\Configuration\Connections\Scripts\PHP_MySQL\_mmDBScripts" to "C:\xampp\htdocs\phptest\_mmServerScripts"
This was EXACTLY the problem. I checked the tutorial and I couldn't even find where the tutorial said to do this. (If I missed it, let me know where in the tutorial it was, please.)
Fixed!

I read this doc - [http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html], this applicable if I Tomcat Admin, but i'am not Admin
I simply user, i.e. I want to place its database on virtual host (Tomcat+(JSP-JSTL)+MySQL).
There is idea how can resolve this problem
Thank you in advance ;)

For all how have similar problem.
Decision instead of these ways
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql" %>
it is necessary to indicate these
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

How can I connect to MySQL external database

Hello.
I have a SAP system running in SQL Server 2003.
I need to connect to external MySQL DB., to operate with this information in ABAP program.
I have done the step necesary... I mean I go to DBCO transaction and configure the connection like this:
DB CONNECTION --> AFIS
DBMS --> MSS
user name --> xxxxxx
DBpass -->xxxxxx / xxxxxx
Conn Info -->MSSQL_SERVER=192.168.1.233 MSSQL_DBNAME=alliance OBJECT_SOURCE=alliance
I do a test program, when I do the statement CONNECT TO, sy-subrc 0 and connection = DEFAULT... I mean, with this form I cannot connect to MySQL Database...
Can you help me to do this?? I think the problem it's the connection string in DBCO... but I'm not sure...,
Would be possible to connect by MySQL ODBC??? I mean , installing the ODBC driver in my SAP server, and using this in ABAP Program??
Thks.
DATA: BEGIN OF wa,
cod_modelo(20),
END OF wa.
DATA: dbs TYPE dbcon-con_name.
DATA: con(20) TYPE c.
DATA : ls_wa LIKE wa.
con = 'AFIS'. "DB Connection in DBCO above
EXEC SQL.
CONNECT TO :con
ENDEXEC.
WRITE sy-subrc. ---> The result it's 4
EXEC SQL.
GET CONNECTION :con
ENDEXEC.
WRITE : con. --> The result it's DEFAULT
EXEC SQL.
SET CONNECTION DEFAULT
ENDEXEC.
write : con. --> The result it's DEFAULT

> It's for it, that when I go to DBCO... in DBMS ---... I can select Oracle, MSSQLServer, DB2... for this Databases..., exists the library (lib_dbsl)???
yes, for all those databases exists the database interface library.
> In resume:
> IT'S NOT POSSIBLE CONNECT TO MYSQL!!! ... I cannot believe it!!!...
Well - as far as I remember there were some times ago efforts to port SAP applications to MySQL. That would explain why there's also a file "DDLMYS.TPL" created if you execute R3ldctl during a system copy - amongst DDL files for all other databases. I believe this was at the time MySQL was promoting SAPDB/MaxDB.
MySQL is historically not a database engine for software, that requires transactional integrity; there were extensions to support that (InnoDB or others) and there was no customer demand in getting MySQL as engine for SAP applications. And only develop an interface to be able to connect to an external MySQL engine is not worth the effort.
However, there is hope Some BusinessObjects applications also run with and against MySQL engines, depending on how the strategy to integrate those into the SAP software stack there may (or may not) be an interface for that database in the future.

guy pls help me to solve this problem. I tried several times to connect my mysql database with dreamweaver but ended up having this error I reinstalled dreamweaver cs4 and XAMPP still the error is not rectified my both remote and local files are stored in XAMPP server location called in c:\xampp\htdocs\htdocs\myweb

MM serverscripts must be at the root level of the virtual server, that is directly in the htdocs folder.
