JavaME and Http.

[mik]

I'm trying to use Java Me ,
My first simple app would connect to a webpage and show html code in a
textbox.
I use code that i found in javax.microedition.io.Httpconnection,but I have
some error.
here is function :

void getViaHttpConnection(String url) throws IOException {
HttpConnection c = null;
InputStream is = null;
int rc;

try {
c = (HttpConnection)Connector.open(url);

// Getting the response code will open the connection,
// send the request, and read the HTTP response headers.
// The headers are stored until requested.
rc = c.getResponseCode();
if (rc != HttpConnection.HTTP_OK) {
throw new IOException("HTTP response code: " + rc);
}

is = c.openInputStream();

// Get the ContentType
String type = c.getType();

// Get the length and process the data
int len = (int)c.getLength();
if (len > 0) {
int actual = 0;
int bytesread = 0 ;
byte[] data = new byte[len];
while ((bytesread != len) && (actual != -1)) {
actual = is.read(data, bytesread, len - bytesread);
bytesread += actual;
}
} else {
int ch;
while ((ch = is.read()) != -1) {
}
}
} catch (ClassCastException e) {
throw new IllegalArgumentException("Not an HTTP URL");
} finally {
if (is != null)
is.close();
if (c != null)
c.close();
}
}


I call function with a button click:

public void commandAction(Command command,
Displayable displayable) { // Insert global
pre-action code here if (displayable == helloForm)
{ if (command == exitCommand)
{ // Insert pre-action code here
exitMIDlet(); // Insert post-action
code here } else if (command == itemCommand1)
{ // Insert pre-action code here
getViaHttpConnection("www.libero.it"); }
} }
When I build ,I have this error:

\myapp\src\HelloMidlet.java:102: unreported exception java.io.IOException;
must be caught or declared to be thrown
getViaHttpConnection("www.libero.it");


1 error\myapp\nbproject\build-impl.xml:183: Compile failed; see the compiler
error output for details.BUILD FAILED (total time: 1 second)
Suggestion?
What is step by step procedure?
thanks,Mike.

You'll have to catch the IOException that getViaHttpConnection may
throw or catch it inside the method.
