Problem connecting a webservice to a 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.

** END NESTED EXCEPTION **
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.

The driver is in right place
Originally I placed him in wrong directory and got an error, indicationg, that Driver class is not found, but then I corrected it, The problem is in connection to database - it doesn't work.
I tired to load the same driver into Netbeans and could easyli create a connection to database, but I get it not working ander Sun Application server

The wireless security setting that the Actiontec modem/router is using may be different...and not compatible....than the setting that the Comcast product was using.
If you think that might the case, and you have the time to troubleshoot......
Temporarily, turn off the wireless security on the Actiontec modem/router
Reset an AirPort Express back to default settings, then see if it will connect using no security and allow an Internet connection when you do the Ethernet port test in the post above again.
If the AirPort Express cannot connect correctly using no security on the wireless network.....then it is a no brainer to know that it will never connect when security is enabled. So, if the AirPort will not connect using no security, you may have an incompatibility issue between the Actiontec and Apple products.
However, if the AirPort Express connects OK with no security, then this tells you that you will need to use a different setting for security on the Actiontec...the same that the Comcast router was using before.....so the Express will have a better chance of connecting.
That setting would be something like WPA/WPA2 Personal, or the same setting stated another way would be WPA-PSK-TKIP.

Problem connecting to webservice in AIR app

Ok, bare with me, I am a newbie to flex development. I am having a problem connecting to a SOAP web service through my AIR app.
I have the service running on a Glassfish server and I have verified that it is working fine.
I have the following cross domain file in my server root (though I'm not sure if this is necessary with an AIR app):
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*"/>
<site-control permitted-cross-domain-policies="all" />
<allow-http-request-headers-from domain="*" headers="SOAPAction"/>
</cross-domain-policy>
I want to create an AIR application that connects to this webservice but every time I connect I get this error message:
"Unable to load WSDL. If currently online, please verify the URI and/or format of the WSDL....."
But...... when I change my AIR application to a web application and run it in the browser it connects to the web service perfectly.

Does anyone have any ideas on this?

Can not connect Fusion Web Application with MySQL database

Hello to everybody, I have installed jDeveloper since 3 days ago and I am still not able to run a simple web application just to try! I have worked previously with Eclipse and NetBeans but none of them had sooo much errors related to everything. I pasted the JDBC driver everywhere in the jdeveloper folders, to JDK and JRE. To be clear, I created a Fusion Web Application, created an AppModule, tested the conncection with the database and it was fine, created a simple jsf page and added one DataView from the AppModuleDataControl to the jsf file. Everything is ok and when I want to run the jsf file I receive this error:

I pasted the JDBC driver everywhere in the jdeveloper folders, to JDK and JRE.
The MySQL Connector Java JAR files are not found in the runtime class of the web application as indicated by the error message java.lang.NoClassDefFoundError, msg=com/mysql/jdbc/DatabaseMetaData

How does J2SE 1.4 connect to Mysql database?

Could anyone please tell me how to connect J2SE 1.4 to MySql database?
I tried to modify "CreateCoffees.java", I don't know how to replace the following two statements:
url = "jdbc:mySubprotocol:myDataSource" and
Class:forName( myDriver:ClassName);
Thank you in advance.
Rayson

It depends on the JDBC driver you are using. If you don't have one for MySQL try out the MMMySQL driver at http://mmmysql.sourceforge.net/. The doc with it explains how to connect to a database.

How to connect to mysql database using a proxy

Folks,
I wrote a program to connect to both webpage and mysql databases. Because my internet has a firewall (proxy) I set up the internet connection like this:
      System.getProperties().put( "proxySet", "true" );
      System.getProperties().put( "proxyHost", proxyHost);
      System.getProperties().put( "proxyPort", proxyPort);
      Authenticator.setDefault(new MyAuthenticator());The http connection works fine. However the mysql database connection gives me an error:

Connecting to multiple mysql databases......

hi everyone,
I had some question, if I'm connected to more than one mySQL database, and I want to create such a table at specified database, what syntax should I write at the executeUpdate() statment ?
thanx

hi everyone,
I had some question, if I'm connected to more than
one mySQL database, and I want to create such a table
at specified database, what syntax should I write at
the executeUpdate() statment ?
thanx
--------The only way this question means anything not completely ridiculous is if you are asking the following.
Your MySQL server is hosting several databases and you want to specify which one in your query.
Yes you can do this but I don't think I would highly recommend it. The syntax is as follows.
Creating a table called mytable in a database called testing
CREATE TABLE testing.mytable (firstname VARCHAR(20) NOT NULL,
lastname VARCHAR(20) NOT NULL,
PRIMARY KEY(firstname,lastname));Basically DATABASENAME.TABLENAME

Update command overwrites 1st record in mysql database

hi
I'm having a bit of a problem with a form I created in livecycle designer.
I have connected the form to a MySQL database.
whenever I try to update a record , retrieved via navigation buttons or search box, the 1st record in the mysql database is overwritten.
I'm using the xfa.sourceSet.DataConnection.update() with and an click event
I have my Stay BOF and Stay EOF set on the data connections.
I'm not sure what I am doing wrong.
The forms Data connections are using sql select query because the table in the database has an auto incrementing column.
any suggestions you guys provide will be appreciated.

Guys, I am still racking my brain. I have taken some screenshots to show you how I have my database tables set up. I was able to get the tables over to the InnoDB type so I can make foreign keys. Here is how I currently have them setup, can someone check this out and see if it's correct?
Table 1 (carinfo)
Table 2 (images)
Thanks

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.
Regards,
Ljubo.

Is it possible to insert data into a MySQL database with Java?

Hello everyone!
I would like to know, if it's possible to insert data into a MySQL database, with a JFrame inside a servlet?
When the JFrame is first created it calls this method:
     * Connects the servlet with the MySQL database.
    private void connect(){
        try{
            Class.forName("com.mysql.jdbc.Driver");
            connection = DriverManager.getConnection(
                    "jdbc:mysql://localhost:3306/data", "root", "omfg123");
        }catch(ClassNotFoundException cnfe){
            cnfe.printStackTrace();
        }catch(SQLException sqle){
            sqle.printStackTrace();
    }Then, when you click the "Add" button, it executes this code:
            add.addActionListener(new ActionListener(){
                @Override
                public void actionPerformed(ActionEvent ae){
                    String employee = employeeName.getText();
                    String[] args = employee.split(" ");
                    firstName = args[0];
                    lastName = args[1];
                    execute();
            });And this is my "execute()" method:
     * Connects the servlet with the MySQL database.
     * - And executes the SQL queries.
    private void execute(){
        try{
            PreparedStatement statement = connection.prepareStatement("insert" +
                    " into employees values(" + firstName + ", " + lastName
                    + ")");
            ResultSet result = statement.executeQuery();
            String fullName = firstName + " " + lastName;
            printer.write("Employee " + fullName + " added.</br>");
        }catch(SQLException sqle){
            sqle.printStackTrace();
    }But when I click the "Add" button, nothing happens.

This is what I use to insert into mysql. It works on windows.
try {
            Class.forName("com.mysql.jdbc.Driver");
            String connectionUrl = "jdbc:mysql://" + loadip + "/custsig?" +
                    "user=root&password=";
            Connection con = DriverManager.getConnection(connectionUrl);
            newproc = jTextField1.getText();
            newsoft = jTextField2.getText();
            newdeb = jTextField3.getText();
            newcust = jTextField4.getText();
            if (newcust.equals("")) {
                errorsig12 = 1;
                jLabel1.setForeground(new java.awt.Color(255, 0, 0));
            } else if (newsoft.equals("")) {
                errorsig12 = 1;
