Using Native Application to open file

This may be of interest to you. I have been looking around the web and found on a post that it is possible to open the real Acrobat viewer from Java, although it is O/S specific.

For windows :
Runtime.getRuntime().exec(new String[]{ "rundll32", "url.dll,FileProtocolHandler", "filename.pdf" });

For a mac:
Runtime.getRuntime().exec(new String[]{"open", "filename.pdf" });

The JDK defines 5 handlers:

* StreamHandler : sends messages to an OutputStream
* ConsoleHandler: sends messages to System.err
* FileHandler: sends messages to a file
* SocketHandler: sends messages to a TCP port
* MemoryHandler: buffers messages in memory

Sun has defined two formatters:

* SimpleFormatter: defines a simple message format containing among other things a timestamp
* XMLFormatter: a message in XML format

A logger with a ConsoleHandler with low priority level:

Logger logger1 = Logger.getLogger("abc.def");
logger1.setLevel(Level.FINEST);
ConsoleHandler c1 = new ConsoleHandler();
c1.setLevel(Level.FINEST);
logger1.addHandler(c1);

A logger with a FileHandler using a home made formatter:

Logger logger2 = Logger.getLogger("abc.def.ghi");
logger2.setLevel(Level.CONFIG);
FileHandler f2 = new FileHandler("%h/mylog.txt", 10000, 2, false);
f2.setFormatter(new MyFormatter());
f2.setLevel(Level.CONFIG);
logger2.addHandler(f2);

Formatters

Every handler must have a formatter defined, and the API has pre-defined a SimpleFormatter and an XMLFormatter which both extend the abstract class Formatter. You may define your own formatter if you like, and it's actually quite simple. You only have to implement the format method. This method receives an instance of the LogRecord class which contains several properties. format returns a string with the data that should be logged. In the next example I've made a formatter that returns the most important properties from the LogRecord:

import java.util.*;
import java.util.logging.*;

public class MyFormatter extends Formatter {
public String format(LogRecord record) {
return
"LogRecord info:\n" +
"Level: " + record.getLevel() + '\n' +
"LoggerName: " + record.getLoggerName() + '\n' +
"Message: " + record.getMessage() + '\n' +
" " + record.getMillis() + '\n' +
"Sequence Number: " + record.getSequenceNumber() + '\n' +
"SourceClassName: " + record.getSourceClassName() + '\n' +
"SourceMethodName: " + record.getSourceMethodName() + '\n' +
"ThreadID: " + record.getThreadID() + '\n';
}
}

Get Java Software Logo

For some reason, ur client might have no or old version of Java Virtual Machine installed.
To ensure they have correct JVM installed. Sun now introduced the "Get Java Logo"

After u signed up the http://logos.sun.com/spreadtheword. You will be able to enbed this logo on ur applet pages.
My registion provided me the follow code snippest:

Small Button

88 x 31

Medium Button

100 x 43

Large Button

170 x 100

For Your Users Who Don't Have Java Runtime Environment Yet

Content owners can dramatically improve their users' experience by embedding the GetJava button within their applet. Doing so means that, if users do not have the Java Runtime Environment (JRE) installed, they will see the GetJava button, rather than a grey box. Here's the sample applet code with the HTML snippet placed within the <applet> tags.

<applet code=applet.class width=425 height=400>

You have visited a page that contains an applet written with Java
technology. Please install the Java Runtime Environment before
refreshing this page. <br>

Mustang's HTTP Server

Alan Bateman has kindly provided me with a link to the HTTP server API documentation. This will soon be hooked up in the Mustang docs.

Several times, I've seen Mustang's inclusion of an HTTP server mentioned. A technical article points to bug 6270015, which asks for support of a lightweight HTTP server API. This bug is marked "closed, fixed". Yet, you won't find anything in the Mustang JavaDoc on it. What's the deal? Well, if we read carefully, Mustang will include an HTTP server API, not JSE 6. If we follow David Herrons recommendation, we should therefore forget about this quickly.

However, that API looks like it had some thinking put into it, is documented and itself distinguishes thoroughly between com.sun.* (sort-of presentable?) and sun.* (don't go there?) packages. Here's how you run a simple server:

HttpServer httpServer = HttpServer.create(new InetSocketAddress(8000), 5);
httpServer.createContext("/", new HttpHandler() {
public void handle(final HttpExchange exchange) throws IOException {
Headers requestHeaders = exchange.getRequestHeaders();
exchange.getResponseHeaders().set("Content-Type", "text/plain;charset=utf-8");
exchange.sendResponseHeaders(200, 0);
OutputStream responseBody = exchange.getResponseBody();
PrintWriter printWriter = new PrintWriter(new OutputStreamWriter(responseBody, "UTF-8"));
for (Map.Entry> entry : requestHeaders.entrySet())
printWriter.println(entry.getKey() + ": " + entry.getValue());

printWriter.close();
}
});

// the server will be single-threaded unless you uncomment this line
// httpServer.setExecutor(Executors.newCachedThreadPool());
httpServer.start();

Simple enough. If this thing sur
