How to get applets running with Java Plug-in on Win but also on Mac OS X???
I've converted to the use of Java Plug-in for my applets, but I need to have those same applets executable from browsers on Mac OS X platform. Surely this has been done, but I don't see how. The browsers I've tried on Mac OS X (Netscape, IE) don't seem to recognize the <OBJECT> tag used for the java plug-in. I've seen no news about the Java plug-in being ported to Macs. How can one get the same applet to run with the Java plug-in on Windows browsers, and also to run with at least one of the common browsers on Mac OS X? Any help would be SO much appreciated!
Those ten dukes look good to me. But the passing of fifteen months has me thinking you've probably moved on. In any case, here's my effort.
I've been through a trial trying to get my applet, developed with 1.4.1_03, to run on my Mac OS X v.10.2.6 in multiple browsers. I'm posting my results here. Comments and feedback are welcome.
JVM support for 1.4.1 is limited to the Safari browser. All other browsers running in Mac OS X that I've tried ( Camino, Opera, Internet Explorer, Mozilla ) are using the 1.3.1 plugin. According to a bug report by Mozilla on this topic ( see Bugzilla Bug # 197813 http://bugzilla.mozilla.org/show_bug.cgi?id=197813 )
with the release of Apple's version of Sun's Java 1.4.1 the applet programming model has changed, and only Safari has adapted with this change. Other browsers, according to the report, could not because of a lack of documentation. The use of the MRJCarbon plugin offered by Mozilla (here - http://www.mozilla.org/oji/MRJPluginCarbon.html) only allows Mozilla to use the J 1.3.1. And I have not found any information on the Microsoft site about how to get IE 5.2 to recognize the newer version of Java.
Regarding the use of the OBJECT tag in Safari, it is a matter of debate. A current post on this topic exists in the Applet Development forum:
http://forum.java.sun.com/thread.jsp?forum=421&thread=441002
In my experience, I have not been able to determine that Safari v1.0 recognizes the OBJECT tag. My experience is that the APPLET tag is required to run applets in Safari. The Bugzilla report echoes the problem with the BadMagicNumber error that can arise in Safari. Nonetheless, I enjoy Safari and I enjoy Mac OS X.

How i get hardware info with Java Applet
Hello Everybody.

Can i get client hardware info with Java Applet
Ýf i can How i do get hardware info with Java Applet.
I need sample code or documentation.

Hello;
Can i get hardware info with Java ?? Have not a know people ?Applets are restricted, unless, as already noted, they are signed and accepted by the user. See

http://java.sun.com/docs/books/tutorial/deployment/applet/properties.html
In general, since Java is designed to run on multiple operating systems and machine architectures it does not provide much access to the underlying hardware. As mentioned, you can access the os via methods in the java.lang.ProcessBuilder and Runtime classes. -
How to get php content with java ??
i have made a php file what will display a number,
here's a example
<?php
if ($action == "answer"){
echo "18274926";
?>
no i want to get the number with java
so here's my java code
import java.io.*;
import java.net.*;
import java.util.Date;
class URLConnecties
public static void main(String args[]) throws Exception
int teken;
URL url = new URL("http://www.gamer.mineurwar.nl/net/javachallenge.php?command=DaTe");
URLConnection urlconnection = url.openConnection();
System.out.println("Type inhoud: " +
urlconnection.getContentType());
System.out.println("Datum document: " +
new Date(urlconnection.getDate()));
System.out.println("Laatst gewijzigd: " +
new Date(urlconnection.getLastModified()));
System.out.println("Document vervalt: " +
urlconnection.getExpiration());
int lengteinhoud = urlconnection.getContentLength();
System.out.println("Lengte inhoud: " + lengteinhoud);
if (lengteinhoud > 0) {
InputStream in = urlconnection.getInputStream();
while ((teken = in.read()) != -1) {
System.out.print((char) teken);
in.close();
}if you change the url ro a .html file it displays the code correctly(source),
but when trying to get the content of a php file (the number)
it says that there is no content from the php file
yhe source of the original php file what's in the code can be found at
www.gamer.mineurwar.nl/net/javachallenge.txtThe 'content' is generated dynamically by a PHP script so the "content lenght" can't be known in advance by the server. For this reason connection.getContentLenght() returns -1; it doesn't mean that there is no content, only that it can't be known how much there will be.
To solve the issue, remove the if statement from around the while-loop:// if (lengteinhoud > 0) { DELETE THIS LINE
InputStream in = urlconnection.getInputStream();
while ((teken = in.read()) != -1) {
System.out.print((char) teken);
// } and this too -
How to make sure an applet runs with Java 5?
Hi all,
First let me say thanks for all the help in the past. You've help me go from noob to intermediate noob. I've just about finished my first applet game which can be checked out here .
Now I've been reading about problems with mac and 1.6. (note it works on Linux). I want to make sure that it runs fine and of course I don't own a mac. So I downloaded the 5 JDK. Selected it as the java platform in Netbeans, compiled and it ran fine.
Questions:
Do I have to always use 1.5 to compile and perhaps set it as default?
Since it works in 1.5, do I compile it with 1.6 and just upload?
I'm worried I'm not testing it correctly. I mean if I have both 1.5 and 1.6 installed on my machine, how to I make sure the applet is only using 1.5 to run?
Thanks

I haven't got a clue RE your problem other than for max-portability you should compile with [-target 1.5|http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/javac.html].
I must say I'm impressed, except I suspect my PC must be substantially faster than any of your test platforms... can you throttle it to CPU performance somehow? Or maybe it's just that my reflexes aren't what they once where.Thanks.
There seem to be two issues. The first is what people are using. This web stats shows pretty poor penetration of 1.6.
[http://www.statowl.com/java.php|http://www.statowl.com/java.php] Penetration: 54% with JRE1.6 + 19% with JRE 1.5. Total 73%.
The second is I've read that mac and 1.6 do not get along except on a 64bit platform.
So for applets there is not much choice but to compile on 1.5 for the broadest user base. I guess the good news is 1.4 and earlier are almost non-existent.

JAI extension automatic installation fail with Java Plug-in 1.4.1_01
Hi everyone,
i have a html page with an applet that use the JAI (Java Advanced imaging) extension. I used to run it with java plug-in 1.3.1_03.
When the JAI extension was not installed, it was automatically downloaded and installed. I use the sun "Signed Auto Installation for browsers" jar available on the JAI download page.
But with Java Plug-in 1.4.1_01, it seems to have a security problem. Is the "Signed Auto Installation for browsers" only java plug-in 1.3 compatible or is there a way to install it with 1.4.
If anyone has encountered the same problem with another extension, it could help me to know how to have it installed automatically with java Plug-in 1.4.
I tested on IE 4 and 6 on Windows NT4 & IE 6 on Windows 2000, and i have the same results.
Thanks
Philippe

I cannot see my Iphone 4 in my device window in the finder anymore. It use to appear so I could copy the camera pictures off of it and transfer them to other folders. Does anyone have and idea how to get it back when you plug it in initially. Thanks
You will want to open iPhoto, go to the iPhoto menu and select Preferences. Under the General tab, next to Connecting camera opens: select iPhoto. Close the preferences and quit iPhoto. Reconnect your iPhone 4. iPhoto should open automatically and offer to import your pictures. Import them and then do what you want with them.
Best of luck. -
Up an running with Java. What tools to download?
Hello, I use to work with Java applications about three years ago, but had switched over to another language. Now I need to develop code using Java again. In fact, I need to reuse some of the code I developed a few years ago. The code does alot with animations. So here is my question.
"What tools do I need to get up and running with Java?"
1. What compiler to use (recommend the best open source editor, or one that is not that expensive)?
2. Where is the Java SDK that I need to download?
3. Will my three year old code still be compatible with the SUN, Java code I wrote 3 years ago?
RalphActually Jwenting is right, IntelliJ is by all measures the best IDE.
I have used textpad, programmers notepad (which I still use for some things), VIM, eclipse for a number of years, intelliJ for a short time, and Netbeans since earlier this year.
textpad - Great place to learn the basics, but once the basics are down you need to find an IDE.
Programmers notepad - love it, still use it for some languages, has some features you will find nowhere else
VIM - You have your vi lovers and your vi haters, I would say I fall into the haters camp but still keep up with it because when you need an editor to make a quick change on some obscure system with very little on it, some version of Vi will undoubtedly be there. Once you get into the flow it is not bad, but there is lots of annoying things about vi and its offspring.
Eclipse - Great IDE, was the better of the free ones for a long time. For me eclipse's strength became it's albatross. That is plugins ofcourse. There are literally thousands of plugins that can make eclipse do just about anything you want. The problem is there is very little oversite so some plugins are great, some good, some ok, some suck, and some are deliberately hostile. You don't really know what you are going to get until you try it, but removing it can be a pain so sometimes you are stuck. Plus getting the plugins to play nice with each other can be a chore, the more plugins you have the harder it gets to get new ones to play nice. It was after a whole day stint trying to get eclipse to work again after picking a bad plugin that i simply decided to give netbeans 6.0 a try since it had what I wanted packaged in already.
IntelliJ - Only got to use this for a short time as they went ahead and bought it at my last job after I gave my months notice for leaving. Guess they figured it would be easier to replace me that way. From the little I got to play with it, it was extremely user friendly to the point of being a pleasure to work with, You definitely got what you paid for.
Netbeans 6.0 and higher - Netbeans pre 6.0 sucked. Even 5.5 was not as good as eclipse at the time of it's release, but was a sign they were headed in the right direction. After releasing version 4 only to have it suck and laughed at in the java community since eclipse was hundreds of times better Sun realized netbeans was making them look bad. So they decided to fix that and decided the best way to fix it was to model netbeans as closely after IntelliJ (which was the best even back then) as legally possible. With each release they get closer to realizing this goal, and since it is free with each release netbeans picks up more and more former eclipse fanbois. It is now at the point where most people following the eclipse vrs netbeans war will agree that netbeans has taken the lead and has more current users than eclipse. I would even wager that most of the people who said netbeans was best in this thread were not long ago eclipse fans. Bottom line, of the free IDEs netbeans is the better choice at this point.
But I got to ask, when you say a salary of R8,000 - R12,000 do you mean monthly income or annually? If annually can you even survive on about $1,000 in US dollars for a year? I mean I make about 8 times that in a month, after uncle sam takes his portion, and i wouldn't call myself rich by any means.
Also jwenting have you tried the newer netbeans? I think if you do you will see they are strikingly similar to IntelliJ in many ways.

How to compile and run a .java file from another java program
hello,
can any one tell me how to compile and run a *.java* file from another java program which is not in same directory?Well a smarter way of implementing this is by using a solution provided by Java Itself.
If you are using J2SE 6.0+ there is an in built solution provided along with JDK itself and inorder to go ahead with solution the below are set of API which you;d be using it for compiling Java Programs (Files)
http://java.sun.com/javase/6/docs/api/javax/tools/package-summary.html
How do i do that ??
Check out the below articles which would help you of how to do that
http://www.ibm.com/developerworks/java/library/j-jcomp/index.html
http://www.javabeat.net/javabeat/java6/articles/java_6_0_compiler_api_1.php
http://books.google.com/books?id=WVbpv8SQpkEC&pg=PA155&lpg=PA155&dq=%22javax+tools%22+compiling+java+file&source=web&ots=XOt0siYe-f&sig=HH27ovuwvJgklIf8omTykUmy-eM
Now once we are done with compilation.In order to run a Specific class all you ought to do is create an object and its specific methods of a specified class included in the CLASSPATH which you can manage it easily by usage little bit reflections.
Hope that might help :)

How can i create messenger with java tv API on STB
deal all.
how can i create messenger with java tv API on STB.
how can Xlets communicate each other?
how?
i am interested in xlet communications with java tv.
is it impossible or not?
help all..You can create a messenger-style application using JavaTV fairly easily. JavaTV supports standard java.net, and so any IP-based connection is pretty easy to do. The hard part of the application will be text input, but people have been using cellphone keypads to send SMS messages for long enough that they're familiar with doing this. This doesn't work well for long messages, where you really need a decent keyboard, but for short SMS-type messages it's acceptable.
The biggest problem that you need to work around is the return channel. Many receivers only have a dial-up connection, ties up the phone line and potentially costs people money if they don't get free local calls. Always-on return channels (e.g. ADSL or cable modem) are still pretty uncommon, so it's something that you nee to think about. Of course, if you do have an always-on connection then this problem just goes away.
This is really one of those cases that's technically do-able, but the infrastructure may not be there to give users a good experience.

I have a client.jar that has a bunch of vm parameters and relies on a few other jars. The jar has the main class specified in the manifest. Ultimately I would like to take the dependent jars and put them in the client jar and use the manifest classpath option. I have been unable to get this to work. What I am finding is that running with java -jar basically ignores all of my vm parameters. I have tried removing the dependent jars and referencing them from the command line classpath argument. This still did not work. The only thing that has worked is not using a client.jar at all and just running my main class with all the vm parameters. This is not an acceptable solution for me. Thoughts?
Thanks,
HowardYes, this is what is so weird about the problem. Neither the manifest class-path option or running with cp is working when the main class lives in a jar.
