How to start java applet with netbeans 6.1

hey,
I want to learn how to start java applet (with database) with netbeans.. I'm new to java...can you show me how can i start..if you have any doc about it can you send it to me..thank you..:)

You really should be asking this NetBeans question at the NB site - these forums are for Java language topics, not NB support.
[http://www.netbeans.org/kb/61/web/applets.html]
Almost any NB question you have can be answered by either the NB web documentation or the NB program's Help.

How to start java app with many jar files

Hi,
I have an application that makes use of 50 jar files. When I try to start the application, I need a very long command line like
java -classpath file1.jar;file2.jar;file3.jar; ... de.me.myapp.myclass
This is not very handy. Is there a shorter way if all jars are in the same directory? I would like a command like this:
java -cp /usr/local/my_jars de.me.myapp.myclass
but this does not work.
Any Idea if there is an easy solution?

How relevant is Java Applet technology in 2006 for wide web deployment?

How relevant is Java Applet technology in 2006 for wide web deployment?
I'm developing a website which requires deployment Internationally to as many users as possible. Many people advise to stay away from Java applets, others say only use Java 1.1 (AWT limitation), some say use Flash, others say stay away from applets and plugins altogether.
Of course it depends on the content. I have interactive 3D content currently powered by Java 1.1 applet BUT I have been using Swing to introduce custom GUI functionality but which I know may limit compatibility. I'm torn by this whole debate and what impact it will have on the relevancy of my website.
How many users out there have browsers that will cope with my content?
Then there's the issue of all the various different browsers nowadays. I'm testing for IE and Netscape on Windows platform, but what about other browsers and OSes on other platforms? I notice that some websites have a page with tables to show users what browser is and is not compatible with their web content. How far must a web developer go to test all these things exhaustively?
Then there's the issue of a 16MB download for the latest Java plugin if a user's system is not up to date. Can all modern browsers handle Java even with the latest Java download?
Or should I just tell the user to get a compatible browser? Another 10-20MB download, depending.
Or how about Flash? That reportedly has a vast International deployment base, but do I need to pay for a Flash editor / IDE / compiler? So far I've been using freeware (HTML, Java, NetBeans, PHP, MySQL, PNG images) to achieve excellent results within my ludicrously limited budget. The Flash Player is only a 930KB download, and that is quite user friendly even if I must tell a user to get the latest version � only 2 minutes download on a 56K modem or about 15 seconds on DSL followed by a 2 second really easy install.
Look here to see where Java ranks against Flash and others :
http://www.macromedia.com/software/player_census/flashplayer/
I know Java. I use it for apps and now applets. I get it to communicate with my server's PHP and MySQL. It works well on my machine, but will my applets work for millions of users world wide with few technical problems? Looking through Java forums I see developers struggling with Java Applets in Safari on OSX but not on Windows. Then another has problems with Applets in IE on Windows but not on Netscape. Then one browser struggles with key events . . . it's like a mine field out there and I'm struggling for clear direction.
Microsoft's support for Java has been poor. If I depend on Java Applets now and for the next year, then will they still be supported 3 or 5 years from now? Or will I have to write off this investment in Java development effort and then switch to something else? Or switch to something else now?
Does Sun Microsystems somewhere reveal how ubiquitous their JVM deployment is?
Perhaps I'm totally misinformed, but Java Applets seem to be dying out. I'd really love to hear from other active web developers out there doing stuff for wide deployment to mass markets.

Since my zwebsite is already using Java 1.1 for 3D visualization I've decided to standardize on Java 1.1 to gain maximum browser compatibility. To add another technology like Flash at this point may just complicate matters, especially for me.
I'm now converting my Swing GUI to AWT. It wastes a lot of time, but the effort should be worth it in terms of the deployment success rate - in theory at least :-)
Just imagine if Java 1 had Swing . . . dream on!
In the deployment stats noted in my first post on this thread they state that Java has 86% world wide desktop deployment. Problem is that I bet that figure only relates to Java1. I wonder what pathetic percentage is true for Java2?
Regarding the use of Java for content rich dynamic content for world world wide web browser deployment . . . I'm rather disillusioned at this point. It seems for this application Java is stuck indefinitely at Java1 and the cool things they developed after that cannot be used effectively. Please note that I am ONLY referring to wide browser deployment. For stand-alone apps and targeted web deployment (where you can reasonably expect your user to upgrade his/her system for a good reason) Java is still very cool.
As for Java WebStart: I can see the uses for it, but it just does not fit into the browser application where the general public enter your web pages and see cool content inside the essential context of your webpage. This last point is vital for any serious web site. If the object of the site is to deploy a useful app to the user (like a forex trading front-end with GUI) then use Java WebStart by all means.
After this website, I'll invest in Flash. I'm sure Flash is not without its share of issues, but it has 97% deployment of nearly the latest versions and user download/upgrade is under 1MB. On top of that it does not seem to suffer from corporate relationship woes like those between Sun and Microsoft.
After all, Flash is labelled as a 'player' and not a Virtual Machine. Mass users out there want to play rather than know about complex and bulky IT stuff.

how to use Java WebStart with EJB ? examples ?Well, for starters these are complementing, not 'cooperating', technologies. I presume, since EJB's do not - directly, at least - communicate with a web browser, that you intend for "Java WebStart" to somehow invoke an EJB?? Java WebStart is a technology for running client-side (Java) applications from the web browser - perceptively, the application resides on the server, but technically it, like an applet, is downloaded to the client and run there. Unlike an applet, however, it is not constrained by "sandbox" restrictions and does not have to be re-downloaded each time it is invoked - though the process allows for automagically updating the client-side with new versions of the application. ;) So, with this in mind, to "use Java WebStart with EJB" means little more than deploying an EJB client application with Java WebStart as the distribution channel.

I don't have any experience with GTO's cards, but one would expect they provide a user guide or a data sheet how to load applications.. Reasons could be:
1. Issuer policy to have a certain security level for content management --> raise the security level to C_MAC + ENC
2. Issuer policy this card is static --> no post-issuance

How to start a application with a login window?

hi there
does anyone have any idea on how to start an application with a login window? a login window is the first frame or window to be displayed when an application starts running. and only correct login id and password have been entered the real application will start. any sample out there? thank you.

You can start a new thread by making a thread object and passing it an implementation of a runnable object. Runnable has just one method, public void run(), this is was gets executed in a second thread. perhaps the code you would use would look something like this.
<code>
// set up thread for login window
new Thread(new Runnable() {
public void run() {
// construct your login window here
// when you are done processing the
// password....
if(goodPassword) {
authorized = true; // a global variable
notifyAll(); // don't forget this
else {
System.exit(42);
}).start();
// control does not stop this code gets executed while
// the above thread is running.
// Set up main program here. This is done in the
// backround.
while(!authorized) {
synchronized(this)
{ wait(50); }
// now when the user logs in this frame pops
// up real quick.
myFrame.setVisible(true);
</code>
Hope you can figure it out.. good luck :)

How to sign the applet with verisign certificate?

Hi,
I got a test certificate from the Verisign.
Now I want to know, how to sign my applet with that certificate?
Thanks,
Siva E.

Hi!
You have to create a keystore wich contains the certificate. I think you call keystore -import "verisign.cert"Try the command, and it will tell you what it needs.
To do the acutal signing of an applet (jar-file), you write somehting like this:
jarsigner -keystore "NameOfKeystore" -keypass "PasswordToPrivKey" -storepass "PasswordToStore" "YourJarFile.jar" "CertAlias"The cert alias is an alias you created when importing the certificate. Hope it Helps!

How to run an applet with .java files in 2 dirrerent directories ?

I have an applet with :
5 .java class files and its .html file in one directory and
2 .java class files ( with identical names) and its .html file in another directory .
How do I go about executing this applet ? In the past all the applets
I have run had all the classes in one directory.
Thank you in advance

If you want them both in the same page, put both applet tags in 1 page,
I could do that but both directories have a SpaceDunes.class
and both directories have a Shot class (diffferent immplementations
but the same name)
so the applet tag
<APPLET CODE="SpaceDunes.class"
CODE="SpaceDunes.class"
This can't be the right approach ? ?
Thank you for your advice

Starting an Java-Applet with https

Is it possible to start a java-applet
from a secure web-page?
https://..../applet.html
If yes - HOW?
null

My code looks something like this
StringBuffer queryString = new StringBuffer(Applet.getCodeBase().toString());
// append all the variables I need here
URL dataUrl = new URL(queryString.toString());
BufferedReader br = new BufferedReader(new InputStreamReader(dataUrl.openStream()));This works from both http and https The protocol is the same as the how the page itself was loaded.

How to start an applet offline with JNLP?

I want my applet to work offline. It uses Java3d and that is why it needs JNLP. I have made sure that it doesn't make any network connections. I have also put the JNLP file that it uses, java3d-latest.jnlp in the same directory as the applet. It finds this jnlp file, but it doesn't find the applet-launcher class. I get "java.lang.ClassNotFoundException: org.jdesktop.applet.util.JNLPAppletLauncher". I try to solve this by putting the applet-launcher.jar in the same directory as the applet, but it still doesn't find the applet-launcher class. What can I do to make the applet start offline?
I need it to work offline, because I am going to make a screensaver from the applet. This is the applet code in the page:
<applet code="org.jdesktop.applet.util.JNLPAppletLauncher"
width=100%
height=100%
archive="astrals.jar,
applet-launcher.jar,
http://download.java.net/media/java3d/webstart/release/j3d/latest/j3dutils.jar,

</applet>
You can view my 3d applets here, they work online:
http://astral.mobile-visuals.com/3d_visuals.php

I think you can do that you have to use a combination of javascript and html. use the Onclick event handler to call a java script function let say startApplet and in this function open a new window and write the <html><applet code= width= height=> </applet> </html> in that window and you will be able to start your applet that way.

Problem Launching Java Applet with Plug-in: Version 1.4.2_01

Hello out there:
I recently installed j2re-1.4.2_01 on my home computer but have been unable to access Web sites emmploying JAva applets. The following is an email exchange with Jeff Hall of Lowell Observatory, manager of an educational site hosted by Lowell, trying to resolve my problem. The messages are better understood if read in reverse order.
I'm hoping that someone will recognize the source of my problem and can recommmend a solution. I would appreciate any help offered.
Thanks,
Mike Coucke
Hi Jeff:
Well, I guess the problem lies with me somewhere. Here's my answer/status to your questions/suggestions:
1) I'm using MS Windows Me version 4.90.3000
2) I do have the directory C:\Windows\.jpi_cache\jar\, but the only thing in it is an empty folder labeled "1.0". The file LP.jar does not exist anywhere on my hard drive.
3) I tried several game sites that utilized Java applets and got the same results: the Java cup in the upper left corner followed a few seconds later by the red "X". So, evidently the problem is somewhere on my end.
I'm going to post our email exchanges in a Java Users Forum managed by Sun to see if anyone out there can solve my problem. However, if you have any more suggestions, I'll be glad to try them.
Thanks for the help.

Mike,
Rats! What version of Windows are you using? It's a little strange to
see the user directory set to C:\Windows; if you're using XP, I'd expect
it to be something like C:\Documents and Settings\Mike Coucke. In any
event, the output that is of concern is these two lines:
java.lang.ClassNotFoundException: LPRemote.class
Caused by: java.net.UnknownHostException: proxy
It looks like your browser is not finding our server's IP when it comes
time to download the necessary Java code.
LPRemote.class is the fundamental code that runs LOPARC, and your
browser should be downloading it automatically when you click connect.
LPRemote.class is stored along with a bunch of other classes in a file
called "LP.jar" that you download from our server. So, if you go to C:
in Windows Explorer and do a file search for LP.jar, you should find it.
On my machine, it's stored in a directory called ".jpi_cache\jar\" in my
user home directory. Let me know if you have this file, or the
jpi-cache directory.
One other thing you might try is going to a different site that you know
uses Java applets -- I think some of the online game rooms at Yahoo use
Java. See if other sites that use Java load correctly. Then we'll know
if it's our server specifically, or a more general problem on your end.

Hello Jeff:
I still have the Java "blues". I followed your instructions, but am still unable to launch a LOPARC session. After an initial failure, I uninstalled all three Java versions I had (1.4.0, 1.4.1, 1.4.2), then reinstalled 1.4.2_01 from the Sun website.
Now, when I try to launch LOPARC, I initially get a blank window with the Java cup in the upper left corner. After about 20 seconds, the cup changes to a red "X". During those 20 seconds, the following appear in the IE message bar at the bottom of the window: "Applet LPRemote notinited" (their spelling) which changes to "Loading Java Applet Failed..." when the red "X" appears.
Following is a copy of the log from my Java Console during all of this:

I'm not a Java expert, so this may be more information than you ever wanted to see.
Once again, I hope that you can help. My experience has been that I usually have some obscure option set incorrectly and that causes me great grief.
Thanks fo your help,

Hi Mike,
Try it now. I think this problem has arisen because Sun just
released a new version of the Plug-in (1.4.2), and when we released the
public beta of LOPARC, only one relevant version (1.4.0) was available
and the LOPARC code was written to look for that by default. I have
just recoded the relevant routines so they should now cause your browser
to simply pick up the latest 1.4 version of the Plug-in you have
installed, whatever it is. I "broke" Java on my machine to replicate
your problem, and the code I inserted today did fix it. Hopefully it
will have the same effect for you. I am running IE 6 and plugin
1.4.2_01 (as accessed via Tools->Sun Java Console).
One broader problem: some (non-LOPARC-specific) users on the Sun
forums have reported the "JRE collision" you are seeing when multiple
versions of the Plug-in are installed on the same machine. So if the
fix I made to our code doesn't work, one option would be to uninstall
all Java components from your computer and do a fresh install of the
latest runtime environment.
Let me know how/if this works. Thanks for the feedback and for your
patience.
Best regards,
Jeff Hall

Hello Jeff:
So far, I have been unable to launch a LOPARC session. I repeatedly
get the following error message:
"Exception: java.lang.ClassNotFoundException: LPRemote.class"
My browser is MS Internet Explorer version 6.0.2800.1106 Initially I was
using Java Plug-In version 1.4.1 and received the error message. I went
to the Sun website and downloaded/installed Java Plug-In version 1.4.2
and still get the message.
Before I try to launch LOPARC, I can select Tools->Sun Java Console from
IE's pull down menu to check my Java Plug-In version. When I try to
launch LOPARC, I get the following message:
"Applet(s) in this HTML page requires a version of Java different from
the one the browser is currently using. In order to run the applet(s)
in this HTML page, a new browser session is required, press 'Yes' to
start a new browser session." If I select 'No', I get the following
message: "Java Plug-in detected JRE collission"
If I select 'Yes', a new browser window opens and then I get the first
message above.
Can you help?

Dear Michael Coucke:
Thank you for registering with Lowell Observatory's online education
site. We hope you enjoy using it and visit regularly as we continue to
expand its features and capabilities. This is a one-time welcoming
email.
For your records, your user ID is xxxxx, and your password is #########.
You'll need to supply these each time you log in.
This site gives you access to research-grade equipment including a 16"
telescope, CCD detector, and image processing software. Our online
archive of data is now available 24/7. The telescope will be opening to
our onsite users in May, and on select nights to the Internet at large
in June.
We have designed this site so you don't need a huge monitor or a
supercomputer to use it. All pages are viewable on screens running at
800x600 resolution or higher. To use LOPARC, you'll need a Java-enabled
browser with the Java 1.4 plug-in installed. If you don't have the
plug-in, you'll be prompted to download it the first time you attempt to
connect. This is an admittedly large (9 MB) but one-time-only download.
This site works correctly under Internet Explorer version 5 or higher.
If you use Netscape, you must be running version 6 or higher, and
display or applet behavior anomalies may occur.
If at any time you can't connect to our server, simply try again later.
We do experience several power outages each year, particularly during
Flagstaff's summer thunderstorm season. Our server is fully protected
and backed up, and can be quickly brought back on line, but any active
user sessions will be lost. Thanks for your patience during these
inevitable downtimes.
Your questions, comments, suggestions, and bug reports about this site
are always welcome. On behalf of the LOPARC development team, thanks
for signing up!

Hi Mike,
I see this in your logs:
Java(TM) Plug-in: Version 1.4.2_01
Using JRE version 1.4.2_01 Java HotSpot(TM) Client VM
User home directory = C:\WINDOWS
Proxy Configuration: Manual Configuration
Proxy: http=proxy,https=proxy,ftp=proxy,gopher=proxy
Proxy Overrides:
I just helped my Dad set up his computer with a new
cable modem, and had the situation where we couldn't
access any secure Web sites. The cable folks had us
disable the proxy. It looks like the error message is
saying it can't find your proxy server, and the logs
you posted say that you've decided to configure your
proxy manually, rather than using the settings from
IE (which is how mine is set up in the plugin
control panel.)
Could that be the problem?
