reading Data from an HTTP Connection

[komomo]

I tried to read Data from an HTTP Connection as a first time.
But it does not work.
The message is
javax.microedition.io.ConnectionNotFoundException: Could not resolve hostname

I tried to open http://www.jimkeogh.com/index.htm. that is the web site really exist.
What steps I have to do?

StreamConnection connection;
		try {
			connection = (StreamConnection)Connector.open("http://www.jimkeogh.com/index.htm");
			
			InputStream in = connection.openInputStream();
			StringBuffer buffer = new StringBuffer();
			int ch;
			while (( ch = in.read()) != -1)
			{
			if (ch != '\n')
			{
			buffer.append((char) ch);
			}
			else
			{
			System.out.println(buffer.toString());
			buffer.delete(0, buffer.length());
			}
			}
			


		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		


	}

Hi Komomo,

Please see this link for make connection in j2me http://www.java2s.com/Code/Java/J2ME/HttpConnection.htm

What I wrote is from the book and it is the first program of that chapter.
I just want to test whether I could access the Internet from my program.
Is there anything wrong in the program or do I need to do other steps?

[komomo]

Can I test that with the emulator?

[quangndba]

Can I test that with the emulator?

Yes, please do it and let me know the result

I am saying that I can't do that.
How I have to do?

[komomo]

I am using eclipse-pulsar-galileo-win32.
java(TM) ME platform SDK 3.0 is used.
The emulator is Defaultcldcphone2.
I have no real device to test.

Hi,
I know that eclipse is great IDE but you have to find J2ME plugin for your eclipse IDE so for easy to instruction you i suggest you to download and install Netbeans then i will follow and help you to build J2ME app. OK
Download netbeans IDE here http://netbeans.org/downloads/start....en&option=java

[komomo]

I cann't access the web site u point out.
The website declined to show this webpage

[komomo]

Have you got what I meant.
I cannot download netbeans.
in eclipse, the local host is ok.
Is there any step to access from the internet?

[quangndba]

Please follow this to install j2me plugin for your eclipse IDE
1. From the eclipse IDE go to Help->Install New Software...

2. Cick on Add... button to add the url for install plugin for J2ME
Name : eclipseme.org
Location : http://www.eclipseme.org/updates/

3. Config J2ME platform (you have installed version 3.0) with eclipse using Platform Components
Window-->Preferences-->J2ME-->Device Management then Import the J2ME SDK 3.0 for Eclipse

4. Open your project then create an J2me environtment to run the J2me app

Before you change your working environment let me tell you that this is issue with the URL and hence the exception was thrown.

Why dont you use the demo URL like the http://www.forum.nokia.com and test the results.

[komomo]

I have tested that URL.
But it does not work.

[komomo]

I have also added as quangndba said.
There is an error message when I add as he said.
But I don't remember the message.
To show u that message, when I add new s/w again, it said that it is duplicate.

And there is still javax.microedition.io.ConnectionNotFoundException: Could not resolve hostname
