Problems connectig my webservice to my mysql database.

Hi,
I am trying to connect a webservice to a mysql database. I am using sun application server 8.1 and Mysql 4.1.
I have been using the application servers examples to achieve my goals thus far. I have made the following progress.
- I have got a simple jdbc web application on the application server to access my mysql database.
- I have got a web service on the application server to work properly, in regards to performing a simple rpc method such as 'sayHello'.
- I now want my webservice to have similar functionality to the jdbc application. A simple query or update to the database installed on the application server invoked from the webservice deployed on the application server.
I have been having difficulty in achieveing this. I don't understand why I can't get this to work as i can achieve access to the database from the jdbc app. I am getting the following errors on the application server log:

I can't think of what the problem may be other then the following issues:
- the mysql database would allow access from the jdbc application as it is seen as a local process whereas it may not for the webservice as it is seen as a remote process???
- I may need to utilize a different datasource class to give the webservice access rights?
Any help or advice in how this problem might be resolved or even just what it is would help me greatly. Thanks for you time in advance.

I am getting this problem from java nio server to java nio client. I get it intermittently on windows. Have not tried other os's. It almost seems like some kind of race condition as my unit test case was passing for the past few weeks and when i changed some code today, it started failing intermittently with this error.

I can't think of what the problem may be other then the following issues:
- the mysql database would allow access from the jdbc application as it is seen as a local process whereas it may not for the webservice as it is seen as a remote process???
- I may need to utilize a different datasource class to give the webservice access rights?
Any help or advice in how this problem might be resolved or even just what it is would help me greatly. Thanks for you time in advance.

Problems with UD Connect to a MySQL database

Hi SAP BI experts,
I am trying to extract data from a table in a mysql Database to SAP BI 7 using UD Connect. I have followed the instructions at http://www.bi-expertonline.com/downloads/Schroeder0604.doc . However, I get an error as soon as I try to create a UD Connect Data Source to an InfoSource using "Create BW DataSource with UDConnect" from the Extras menu. I can set up the RFC destination as well as the UD connect source. Regarding the UD Connect source object I get an error message "RSSDK|100|Connection could not be established". I already checked if my settings in the connector container service of the Visual Administrator are correct. They are. I have tried to access the data using a simple java programme and it worked fine. My configuration properties are:
DriverName       com.mysql.jdbc.driver
Password         xxxxxxxxxx
URL                 jdbc:mysql://brainsapgw:3306/bi_test
UserName        sap
Does anyone have some hints for me what could have gone wrong with it? As far as I can see, the properties should be fine as they work with a normal java programme.
Thanks in advance
Martin

Hi SAP experts,
it's now working. The problem was that I provided "com.mysql.jdbc.driver" as Driver Name instead of "com.mysql.jdbc.Driver".
Cheers

Problem connecting my webservice to mysql database

Hi,
I am trying to connect a webservice to a mysql database. I am using sun application server 8.1 and Mysql 4.1.
I have been using the application servers examples to achieve my goals thus far. I have made the following progress.
- I have got a simple jdbc web application on the application server to access my mysql database.
- I have got a web service on the application server to work properly, in regards to performing a simple rpc method such as 'sayHello'.
- I now want my webservice to have similar functionality to the jdbc application. A simple query or update to the database installed on the application server invoked from the webservice deployed on the application server.
I have been having difficulty in achieveing this. I don't understand why I can't get this to work as i can achieve access to the database from the jdbc app. I am getting the following errors on the application server log:

Mysql database, counting records

Hi!
I have to store measured data to MySQL database. During this process I would like to count a number of records in a database table. It is also necessary to filter records. I'm using the SQL statement as follows:
SELECT COUNT (fieldname) AS cnt FROM table WHERE condition
Because I haven't got any result I've created a small database "mysweetdb" and table "icecream" to test my VIs (see picture bellow).
The VI is attached. The result of counting is a 2D array (DB Tools Fetch Recordset Data.VI output) with one element (one row and one column). This element contains no data.
I usually don't give up easily so I've created a similar MS ACCESS database and counted data in it. I've got a correct answer: 3. So it might be possible that there is something wrong with MySQL driver. But I've created a small Delphi project and I've counted records in MySQL database and MS ACCESS database. Both results were correct.
Can anyone explain where is the problem in communication between LabView and MySQL database?
Versions: XAMPP for Windows 1.7.3, LabView Developer Suite 2010 SP1, MySQL 5.1 ODBC driver
Thanks in advance for your suggestions.

ContDivConsult,
thank you for your answer. An updated version of my VI is attached. It uses two options: LabSQL library and DB Connectivity Toolkit. LabSQL gives correct results.

Problem with connection in Mysql database in struts application

Helllo
i've just started learning struts for my new project where i'm having problem in accessing mysql database
the datasource being defined in struts-config.xml is as follows:
<data-sources >
    <data-source type="org.apache.tomcat.dbcp.dbcp.BasicDataSource">
      <set-property property="driverClassName" value="com.mysql.jdbc.Driver" />
      <set-property property="user" value="root" />

      <set-property property="readOnly" value="false" />
      <set-property property="autoCommit" value="true" />
      <set-property property="loginTimeout" value="" />
    </data-source>
</data-sources>as i run the application
it gives the errors HTTP status 404-Servlet action is not available
Thx in advance

student-java wrote:

HTTP 404 is a "Page not found" error. The request URL is simply wrong. Either there's a typo in the URL, or there is a typo in the servlet mapping, or the servlet is not there where you think.

Strange problem with MySQL database

Hello,
I'm totally puzzled by a strange error occurring with PHP/MySQL on my website... I hope someone has got an idea of what's going on and can let me know.
In short, I have a MySQL database set up on the remote server where the website is hosted. Some pages of my website access this database with PHP.
If the website is viewed with a browser in Windows (Firefox), it works well, the database data appear on the pages.
If the website is viewed with a browser on Mac OS (Firefox, Safari), it doesn't work: the database isn't accessed, I get no error, just everything on the page below my PHP code is missing.
I've attached two screenshots to show this. The website URL is: http://www.cerc.co.uk/CERC/v02/
The pages were this occurs are: the home page (index.php and alternative index2.php), the Abous us/News page and the About us/News/Archives page.
I really don't get where my mistake is. I would like to keep the remote server connexion details outside the root folder, but I guess that if there is no solution to this problem, then I'll have to move it back (I think it might have worked like that).
Thanks in advance for any comment,
Emilie
More details
I'm using DW CS4 on Windows XP emulated via VMware on Mac OS 10.5 (don't ask why, I wasn't given any choice). I've set up a localhost server on XP via XAMP and the news database is also there.
Because I'm currently flipping often between the testing server and the remote server, I quickly got fed up to change all the time the connexion mode to the database (localhost or remote server) and have to resynchronise the files each time. Hence I decided to automate a bit the way the database is connected to.
1. These 4 HTML pages with PHP code have got the below two lines when the PHP code starts:
$pathpfx = "../.."; // see mysqlconnexion.php
include('assets_design/php/mysqlconnexion.php');
2. mysqlconnexion.php (see code below) calls a "connexion" file (in PHP) depending on the value of one parameter ($conxchoice). If $conxchoice = 1, the "connexion" file on the localhost is called. If $conxchoice = 2, the "connexion" file on the remote server is called. I've stored the appropriate version of mysqlconnexion.php on the localhost and the remote server (and I have checked it a million of times, they're in the right place).
<?php
// This code is called by and therefore included in the code of some PHP pages,
// independently of where the pages are located within the website folder.
// - Connexion to local server: I couldn't get the function include_once to work
//   with a relative path, hence the use of an absolute path.
// - Connexion to host server: I couldn't get the function include_once to work
//   with an absolute path, hence the use of a relative path. This leads to the
//   following problem: the path of conxsrv.php needs to be adapted to the
//   position of the calling PHP page within the website, in order for
//   conxsrv.php to be found on the server (it is located outside the website
//   root folder). The variable $pathpfx is used for this purpose.
$conxchoice = 2; // connect to 1 = testing server, 2 = host server
// Connexion to database
if ( $conxchoice == 1 )
{ include_once('C:\xampp\htdocs\CERC\assets_testing_server_only\conxloc.php'); }
if ( $conxchoice == 2 )
{ include_once("$pathpfx/cgi-bin/sqlconx/conxsrv.php"); }
?>
I would guess that a first hint of solution lies in the comment block, but I've really tried everything I could think of to work with relative path/absolute path respectively, unsuccessfully.
3. The "connexion" file looks like:
<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_conx = "aaa";
$database_conx = "bbb";
$username_conx = "ccc";
$password_conx = "ddd";
$conx = mysql_pconnect($hostname_conx, $username_conx, $password_conx) or trigger_error(mysql_error(),E_USER_ERROR);
?>
With aaa, bbb, ccc and ddd the appropriate value depending on the file. The # lines were introduced by DW when these files were created (I've then changed the variable names and moved the files to another place).
Screenshots

Well, my question has actually not been answered yet but the problem, as strangely as it appeared, has now disappeared. Best but scariest of all, I didn't do anything. Weird.
Hope it never comes back,
Emilie

Any problem with a single MySQL database used on more than one site?

I have a set of multiple sites hosted separately I'm working on. I'd like to set up a PHP/MySQL database on one site, and be able to pull data from it for completely separate sites. Seems like it shouldn't be a problem. Are there any problems with doing this I need to be aware of?

I've set up databases on three different hosts, and in all cases I could access the databases from outside the domain of the site itslef. GoDaddy is one of them, they used to restrict it, but now they give you the option when setting up a new database on your account.

MySQL database - Recordset's echoing problem

Gary, David & any other PHP wizards, listen up -
Today I decided to use a MySQL database to hold my articles
in, and then
call them with a recordset when applicable. Everything works
really, really
nicely except for one thing.
If you go here:
http://sourtea.com/articles2.php
And select "Read this article" for any of the articles,
scroll down to the
bottom where the comment form is and you'll see some PHP code
being
echo'ed - which isn't supposed to be.
I've noticed in IE - it's always displayed with all articles,
but on
Firefox, it seems to only happen with the first article you
open up, then
all the others are fine.
I'm calling the recordsets inside of my php cases, for
example:
<?php
break;
case 10:
?>
<?php echo $row_getArticles['textfields']; ?>
<?php
break;
case 20:
?>
And so on.
Now, everything in the "textfields" row is the physical HTML
and PHP code
that will write and display the article and the comment form.
It seems that something is getting scrambled, or that I need
to write the
PHP code differently inside the table...
Help?
Thanks for your time,

Delivering accessible websites to all ...
=============================================

Hi Joe -
I did cut and paste the code from DW into the table. I just
finished up,
actually, with another solution. I entered the code for the
comment form
into a .txt file, and used it as a PHP include for the
articles.
Also, for the action of the form (since it's the same form
being used for
three different pages) - I set a variable when it calls a
certain Recordset,
and then did an "if, elseif" statement inside the .txt file
where it will
echo out the appropriate page, depending upon which article
the user is at.
For example (from my code):
<form id="contact_form" action="articles.php?ref=<?php
if($var == 10) { echo
'10'; } elseif($var == 20) { echo '20'; } elseif($var == 30)
{ echo '30'; }
?>" method="post">
That's was really the only problem I had to overcome because
I'm using the
same form for all three articles (assigning the proper
action).
Thanks for the help, Joe - though, I'm not sure if your
suggestion would
have worked! Maybe I'll try it sometime...

It's not common to create databases with Java. I'd say this is especially true of JSPs. You'll have to GRANT permission to access and create tables to every single user that comes in? Are those tables cleaned up when users are done, or does the number of tables grow as the number of users grows? One table per customer? Sounds more like session or cookies to me. Do you validate users to make sure that only authorized users can create tables? Lots of problems, and it doesn't appear that you've addressed any of this from the code you've posted.
It's a bad idea to have code like this in a JSP. Those are for view only. Better to put database code on the server side where it belongs.

Problem Seeing MySQL Database

I am trying to migrate a MySQL 5 database to Oracle. Using these forums, I successfully resolved my connections problems, but now I have a new issue. When trying to capture my database, the capture screen connects to the server and then gives me a list of databases that I can capture. The problem is that it only lists the "test" database, not the "mysql" database where the data is.
Any ideas why it does not see all the databases?

the user root must have
mysql>grant all on *.* on root;
How did you get run the mysql 5 plugin?
I just see plugin for mysql v 3 and 4.
Thanks

use this ...

Connvehicle_details.prepareStatement("INSERT INTO

Connecting to a Mysql database using CF Administrator and DW

I can't create a mysql datasource in CF Administrator.
If I use the following datasource settings in CF
Administrator:
JDBC URL: jdbc:mysql://localhost:3306/test
Drive Class: MySQL Connector J
AND (note the emphasis) I set my local and remote folders in
my DW site local folder, remote folder and testing server folders
all to C:\CFusionMX\db\, I can connect to my mysql database in CF
Administrator.
However, with these DW site folder settings, DW doesn't
recognize any databases (Access or Mysql) at all.
When I change my DW site folder settings to 'wwwroot'
(e.g.local folder C:\CFusionMX\db\' is changed to
'C:\CFusionMX\wwwroot') DW now lists all my CF Administrator
databases.
The problem is CF Administrator can't connect to my Mysql
data sources. It gives me the error:
"Connection verification failed for data source: javaserver
[]java.sql.SQLException: SQLException occurred in JDBCPool
while attempting to connect, please check your username, password,
URL, and other connectivity info.
The root cause was that: java.sql.SQLException: SQLException
occurred in JDBCPool while attempting to connect, please check your
username, password, URL, and other connectivity info"
I've tried changing the 3306 port to 8500, but this doesn't
help.
My java path and connector file is:
C:\CFusionMX\wwwroot\WEB-INF\lib\mysql-connector-java-3.0.17-ga-bin.jar,
Is this a ID/password problem? I've tried both 'root' and
leaving the ID field in the CF Administrator add data source block,
both to no avail. I don't have a password set in Mysql for 'root'
either.
Any help would be gratefully appreciated. I've been working
on this for weeks and keep running into one problem after another.
Thanks a million in advance.
Sincerely,
Graham A. Kerby

1) ensure mysql server is running
2) there are numerous tutorials for mysql installation out
there
3) there are good free mysql admin tools out there
4) use both the above to verify your mysql installation is
correct
5) please tell me you do have your zonealarm DISABLED
