Web Service implementation on the client I will be creating a web service as part of a group project for university, which will be developed using Java within the Eclipse IDE. 

Having no prior experience using web services, I managed to find some tutorials that were useful, but struggled to find enough database code examples which suited my needs (though, perhaps I was looking in the wrong places).

My team member has failed to produce even the slightest example of a web service client, so I have taken it upon myself to develop both the web service and client. 

I would like to know whether or not my web service example method is suitable for client-side implementation: i.e - Do I have to change the method in order for the client to execute the method or is it acceptable as is?

(I have been creating basic web services using the axis2 framework and running them on the Apache Tomcat server. However, I am open to any suggestions or recommendations in regards to alternative servers and frameworks.)

public void addProduct(String name, String genre, String platform, String developer, String publisher,
int ageRating, double price, int quantity, String description)
{
try
{
// 1. Connects to the database
Connection connection = DriverManager.getConnection("jdbc:mysql://localhost/Products", "root", "root");

// 2. Executes SQL query
String SqlString = "INSERT INTO Games(Game_Name, Genre, Platform, Developer, Publisher, Age_Rating, Price, Quantity, Description) VALUES(?,?,?,?,?,?,?,?,?)";

PreparedStatement prepStatement = connection.prepareStatement(SqlString);
prepStatement.setString(1, name);
prepStatement.setString(2, genre);
prepStatement.setString(3, platform);
prepStatement.setString(4, developer);
prepStatement.setString(5, publisher);
prepStatement.setInt(6, ageRating);
prepStatement.setDouble(7, price);
prepStatement.setInt(8, quantity);
prepStatement.setString(9, description);    

// 3. Updates the database using the SQL query
prepStatement.executeUpdate();

// 4. Closes database connection
connection.close();
}
catch(Exception e)
{
System.out.println("Problems were encountered when trying to insert new records to the database. (Ref. to SQL statements)");
}
}
}
Looked briefly into your program, here are few points:

  suitable for client-side implementation


Web Client implementation doesn't need the actual implementation, if the service is hit able, it's client can surely be written. 

addProduct(String name, String genre, String platform, String developer, String publisher,
int ageRating, double price, int quantity, String description)


Why not create a Product bean and pass it instead of so many params?

This seems fine but from the learning perspective, give Jersey a try.
