URGENT JAVA HELP NEEDED A question to all you Java coders

kelso · Mar 24, 2015

A friend needs some java help and as he is not a member of BHW and does not know anything about it so I reckoned I?d try to help him by sourcing some advice from here.

So the task in hand is (so I?ve been told) pretty simple:

There?s a mySql database with 2 columns: cars and pictures.
In netbeans we have a class connector with which we are making a connection to the database.
He?s made a simple GUI (JFrame) with 2 buttons.
He wants 1 of the buttons to fetch car1 with picture1 and the other to fetch all cars with their appropriate pictures.

So the question is: what code should he add to those buttons so that they would fetch and display that data?

This is the code that handles button events.

And in that button event you need to query the DB and then display it on some component, which you can learn here: http://docs.oracle.com/javase/tutorial/jdbc/basics/jdbcswing.html

So my friend managed to get to a point where he wanted. Thanks bartosimpsonio for the try, and thanks to the others that contacted me and chimed in to help (not in the thread apparently).

So now I have another question on his behalf:

How to deploy an application in a web server?
He made an application in netbeans which reads from a database and shows the result in UI. When he secelts to deploy the project in a glassfish server what happens next is that localhost:8080/myapp opens but it only says "TODO write content".

In the project he has a file index.html with the following contents:

<html>
<head>
<title>TODO supply a title</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<div>TODO write content</div>
</body>
</html>

And apparently his browser displays only this: <div>TODO write content</div>

So the question now is: How to upload the whole application on the server?

I hope I've paraphrased him correctly but I think that someone who understands thiss will know what I mean. Is it something that needs to be added to that index.html so that it connects to the application or what idk...

He wrote a lot of code to make this app - that shows users and pics. Now he needs to display it in a browser and for that purpose he needs to deploy it on a server. BUT when he opts to deploy it it only shows that body part from that html and the program is nowhere to be seen...

Thanks a lot for the input! Also could you shed some light and details about the war file necessity? Thanks again!

Anyone else?
