Hi Freunde!
Ich versuche aus einer Applikation den Standard Browser zu Öffnen. Dieser gelingt mir auch in "Eclipse". Wenn ich jedoch diese Applikation in eine Jar Datei Exportiere funktioniert der Aufruf nicht mehr. Als Bemerkung: Die Jar Datei startet ordnungsgemäß, es besteht keine Fehlermeldung
Hier der Code:
[HIGHLIGHT="Java"]String classDirectory = getClass().getResource(".").toString();
classDirectory += "home.htm";
new BrowserControl(classDirectory);[/HIGHLIGHT]
[HIGHLIGHT="Java"]import java.io.IOException;
public class BrowserControl
{
public BrowserControl(String url) {
boolean windows = isWindowsPlatform();
String cmd = null;
try
{
if (windows)
{
// cmd = 'rundll32 url.dll,FileProtocolHandler http://...'
cmd = WIN_PATH + " " + WIN_FLAG + " " + url;
Process p = Runtime.getRuntime().exec(cmd);
}
else
{
// Under Unix, Netscape has to be running for the "-remote"
// command to work. So, we try sending the command and
// check for an exit value. If the exit command is 0,
// it worked, otherwise we need to start the browser.
// cmd = 'netscape -remote openURL(Welcome to JavaWorld.com)'
cmd = UNIX_PATH + " " + UNIX_FLAG + "(" + url + ")";
Process p = Runtime.getRuntime().exec(cmd);
try
{
// wait for exit code -- if it's 0, command worked,
// otherwise we need to start the browser up.
int exitCode = p.waitFor();
if (exitCode != 0)
{
// Command failed, start up the browser
// cmd = 'netscape Welcome to JavaWorld.com'
cmd = UNIX_PATH + " " + url;
p = Runtime.getRuntime().exec(cmd);
}
}
catch(InterruptedException x)
{
System.err.println("Error bringing up browser, cmd='" +
cmd + "'");
System.err.println("Caught: " + x);
}
}
}
catch(IOException x)
{
// couldn't exec browser
System.err.println("Could not invoke browser, command=" + cmd);
System.err.println("Caught: " + x);
}
