How to load a MediaFile in an Applet?

Hi,
I am new at Java programming.
For a project I have to implement a media player and open a media-file via FileChooser. I managed to load files via HTML-Task "value". My question is: how can I use the FileChooser to do that?

Yes you can create a signed Applet to do this but what is the point? If you want to make an Applet to play media files then surely the media files to be played should reside on your server. If this is the case then there is no point in opening a file dialog to browse the client machine but rather your Applet should hold a list of files available to the user and present them with some means of choosing which one they want loaded - a JList or a JComboBox perhaps?

How to load a java card applet into a java card

Dear All,
I am a novice to java card technology..
I have done some search on how to load a java card applet into a smart card but haven't found a satisfactory answer. I have read about installer.jar and scriptgen tool but I want to load the applet from a java program and not from command line. It would be of great help if somebody can help me out.
If somebody can share a sample program which load a javacard applet(.CAP file) into a smart card, I will be very thankful.
I am able to find some client applications which help us send APDU commands and recieve response APDU's to interact with an applet loaded on to the smart card but not application which actually load the applet.
I have heard of OCF and GP.. some say that OCF technology is outdated and no longer in use.. can somebosy throw some light on this too..
cheers,
ganesh

hi siavash,
thanks for the quick response.. i checked out GPShell as suggested, it looked like a tool by which one can load an applet on to card and send some sample apdu commands... but I want to load the applet from the code.
My application should look something like this.. it will be a swing applicaton where I have a drop down with a list of readers, I select the one desired and then click on "LOAD" after inserting a blank java card, at this point my applet which is stored in my DB should get loaded on to the java card. The next step should be to personalize it where I enter the values for the static variables of my applet and click "PERSONALIZE", at this point all these values should be embedded into APDU commands and sent to the java card for processing.
For achieving this I am yet to find a comprehensive sample or documentation on the net.
Please help...
regards,
ganesh

Info on how to load jdk 1.1 applet

I am totally new to this technology.
How do I load a jdk 1.1 applet onto a geocities website?
Do I need a special program to run the applet?
I have uploaded the applet and cannot figure out how to operate it, I can find no html or class files.
this is an applet for creating islamic tiling and interlacing, here is the url, if you are willing to come this far with me
http://www.cs.washington.edu/homes/csk/tile/islam/
Sorry, But I'm an artist and not a web site designer.
Please explain in very simple terms
Thank you
Storm

Use the HTML applet tags, if you know HTML. If all you want to do is the applet and nothing else, then just create the following HTML file in simpletext (save it as FileName.html), or even geocities file manager:
html
<applet code = "ClassName.class" width = 400 height 400>
</applet>
/html
The numbers and file name listed above are just ones I used as an example. Use whatever ones you need to make it big enough and to load the class you want. And remember to put the < and > in the HTML tags, I didn't so that it would show up on this forum.
This procedure WILL NOT work with Yahoo! PageBuilder, in case that's what you are using.
Remember to upload the CLASS file into your geocities file manager/directory or it will not work.
If all you want to do is load an applet and it doesn't work, then their is something wrong with your browser (probably because it doesn't support JAVA).
Another good idea would be to download jdk 1.2.2 or jdk 1.3, probably found at sun.com somewhere (I'm still trying to find it, hehe!)
Tell me if it works or not and whether or not you understand what I'm talking about. Thanx.

How to load an Applet application for 1000cards?

Hi Friends..
I want to know How to load an Applet application for 1000cards?..
Assume that, i have an Applet application that need to loaded into 1000cards..
So, how to solve this?
Do i must to load an application manually for each card?
Is there any another way?
Thanks in advance..

for 1000 cards you can use a "small" printer like an evolis "dualis" or something like that
we've produced thousands of cards with this method in my company.
the pro is that you can also print the cards in the same time.
they usually have simple APIS like get_new_card_from_loader(), put_card_on_contacts(), eject_card()
you can connect any reader on the printer , the raw card contacts are available on a connector.
some printers also have contactless couplers.
but remember that deploying cards in the field is not just loading an applet.
it's also a cryptographic challenge, you need to change the card keys or anyone will be able to play with your cards, adding and removing applets as they want.
typically this is achieved by using an ultra secret mother key and whatever derivation algorithm you like using data from INIT UPDATE as diversifier. example, you can TDES cipher part of the INIT UPDATE data using the mother key as TDES key, or use something involving SHA1, using a HSM if you are serious, etc.
for your entertainment here is a high volume card personnalization machine. That's amazing.

How to load an applet in a swing frame?

Hi All,
Can any one tell how to load a HTML applet in a Swing frame, I have a requirement where in the swing frame must contain a HTML applet.
Thanks in advance...

Also, what is an "HTML" applet and how is it different from a regular applet or JApplet? I feel a case of jargonitis coming on.

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 load an applet using custom classloader ?

Hi All,
How to load an applet using custom classloader rather than using default browsers classloader i.e AppletClassLoader usually ?
Regards,
Kumar.

I would guess that that would require two applets.
The first does nothing but create the custom class loader and then load the second applet.

Loading an image into an Applet from a JAR file

Hello everyone, hopefully a simple question for someone to help me with!
Im trying to load some images into an applet, currently it uses the JApplet.getImage(url) method just before registering with a media tracker, which works but for the sake of efficiency I would prefer the images all to be contained in the jar file as oppossed to being loaded individually from the server.
Say I have a class in a package eg, 'com.mydomain.myapplet.class.bin' and an images contained in the file structure 'com.mydomain.myapplet.images.img.gif' how do I load it (and waiting for it to be loaded before preceeding?
I've seen lots of info of the web for this but much of it is very old (pre 2000) and im sure things have changed a little since then.
Thanks for any help!

How to load .cap on a smart card

I am very confused with java cards. I wrote an applet for java card. Tried it in Eclipse+JCWDE. Send some APDUs to it with apdutool.bat. Works fine!
However, I want to go further and try it on a real smart card. The only problem is I do not know how to load .cap file onto my card. I tried to find some forums, references or something like that, but all I found was "I tried to load, but get error" or something like that.
I use JCOP tool for Eclipse (if that to any help)
Can someone explaine to me how loading works in princip? Is their any classes that can be used to simplify the task?
Any help is appreciated

How do I enable capability to run applets?

I was trying to access and online course from a site I had success with a few weeks ago (February, 2014). Today, March 3, 2014, I was unable to load the course from the course menu.
I used the site system requirements check and all was well except capability to run applets.
I am running OSX version 10.6.8, Safari 5.1.10, Java SE 6 version 1.6.0_65-b14-462.

How to load a Jar file in the class path?

How to load a Jar file which contains class files, images, etc.. in the classpath without using URLClassLoader.

You don't "load" jars. If it's on the classpath, you can obtain individual resources from it using various methods on either Class or ClassLoader. Do you mean "how to add a jar to the classpath at runtime"? Can't be done without using a classloader, typically URLClassLoader or a subclass thereof. Why you want to not use the proven method is beyond me. Presumably because you don't understand classloading. In which case, forget it.
