Hi

I dont know how to connect mysql with ECLIPSE in RCP application. Please send me the sample code of connecting mysql sever with ECLIPSE in RCP application.

Here i have created menu File->Member->Addmember and when i click the items which i have specified appears on the screen such as label,text,button controls etc...

But when i click the submit button the mouse down procedure invokes and the validation code which i have specified executes.

Also i want the details to be updated in mysql database. Plaese send me the connection procedure....

Please help me....

You can't compary strings like that; use the String.equals() method instead or
in this particular case you can check the String.length().

Connecting to your database is the same as it was in your previous two posts.

Hi

I want to use those connectivity codings in mouse down procedure. But i can't use public static void main(String args[]) throws Exception, in this RCP application. Also i want to use throws Exception. What can i do? I want these connectivity codings to be worked when i click the submit button.

Please help me...

Please rephrase your question; all I can see now is that it is certainly *not* about
MySQL connectivity. (btw, use those [ code ] ... [ /code ] tags when you post
code and also don't post *all* of your code all the time).

kind regards,

Hi

Sorry for posting all the codes. Can you please send me the example code for connecting mysql server with Eclipse in RCP application. I dont know how to do this.

Since RCP application doesn't use public static void main(String args[ ]) method, i dont know how to include the connectivity codings as shown below,

Connectivity Code to mysql server:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class MysqlConnect {

public static void main(String[] args)throws Exception{
System.out.println("MySQL Connect Example.");
Connection conn = null;
String url = "jdbc:mysql://localhost:3309/";
String dbName = "ananthu";
String driver = "com.mysql.jdbc.Driver";
String userName = "root";
String password = "sa";
try {
Class.forName(driver);
conn = DriverManager.getConnection(url+dbName,userName,pa ssword);
System.out.println();
System.out.println("Connected to the database");
System.out.println();
Statement stmt = conn.createStatement();
ResultSet reset = stmt.executeQuery("select * from customer");
System.out.println("Name\t\tAge");
System.out.println();
while(reset.next()){
//System.out.println(reset.getString(1));
//System.out.println(reset.getString(2));
System.out.println(reset.getString(1)+ "\t\t" + reset.getString(2));
}
conn.close();
System.out.println();
System.out.println("Disconnected from database");
} catch (java.lang.ClassNotFoundException e) {
e.printStackTrace();
}
}

}

I want to include these codings in mouse down procedure of my project in RCP application as i have sent in the first post of this topic.

Please help me...

I know nothing about RCP nor SWT; I guess that you have to supply some callback
class or method or implement some interface; that will be the starting point of
your application and somewhere in there you should build a connection with
your database.

Hi

Ok. I will try.Thanks for your kind guidance. Your cooperation and guidance is good. Carry on...

We will meet in the next discussion...

Hi

I have included the external jar file of mysql driver in the project in the java bulid path. Please can you send the solution for me?

I have included the external jar file of mysql driver in the project in the java bulid path. Please can you send the solution for me?

This is the same classpath issue again: the jvm simply can't find that class; you
must've made a mistake somewhere; all you have to do is check it all and fix it.
(typo? set the buildpath in another project mayhap?)

kind regards,

Jos

Hi

I have added the jar file of mysql driver in this project in the java build path. But my project is a plug-in project which is RCP application. Then how can i add the jar file in this type of application.

Same errors which i have specified continue to appear in the console window.

What can i do?

Please give me the suitable procedure so that i can complete my project...

Please help me...I am too tired...
