Java Multicast on Internet

Hi every body,
I have a multicast application and
i want to make it running on Internet.
Knowing that i have no multicast IP address,
how i can configure windows 2000 (or XP)
to accept multicast packet on Internet.
Regards

I think the question is how do you get the routers on the internet to support multicast?

Java Docs for Internet sales

I was looking for the ISA Java docs and tried to download the file ISAWAC40SP09P_9-10002109.SAR, but I cannot find it anywhere. SAP site has file ISAWAC40SP08_0-20000529.SAR but the javadocs are missing. Could anyone please let me know the location from where I can download the file ISAWAC40SP09P_10-10002109.SAR or alternatively Java docs for Internet sales

Hi Pankaj,
you can try with the first patch of the SP 9 - for example try the file ISAWAC40SP09_0-10002109.SAR. Extract the file using the sapcar program and search for docs.sar file where the documents are.
I hope this will help you.

Hi I nede Java for my Internett banking, but I can't download this. Any ideas ?

Hi I need Java for my Internett banking, but I can't download this on my new I pad. Any ideas?

The iPad doesn't do Java. (Why'd your bank choose Java of all things for their internet banking?!)
If, on the other hand, you mean JavaScript - which is entirely different from Java - that isn't something that needs to be downloaded. Your iPad should be just fine with JavaScript out of the box, though obviously some things won't work (like anything dependent on mouseover events).

How to do a program with java user intarface (internet app) and c++ core

I want to do a program to run on the internet with java
but to run the mathematical core with c++ on a SUN machine.
so, any help will be cool!, any tip about this subjet
will be apreciate!

thanks!

One option is to use Java Native Interface (JNI).

Invoking a specific version of java over the internet

According to [this page|http://java.sun.com/j2se/1.5.0/docs/guide/plugin/developer_guide/using_tags.html], the applet tag should be used if the web page is accessed through the internet and object or embed ought to be used if it's through an intranet. Why?
Later, that article says that if you want to invoke a specific version of Java that you can do so with either of the intranet tags (using a specific classid for the object tag or a specific type for the embed tag), but doesn't say anything about doing it with the applet tag, making be conclude that, with the applet tag, it's not possible.

You said "I will not try to guess what that doc. meant." That doesn't necessarily mean that there are others who can't. Maybe there are people who post on forums.sun.com that don't post on comp.lang.java.programmer? If anyone there knew, it seems like they would have responded?
The <https://jdk6.dev.java.net/deployment_advice.html> link... I dunno... it didn't seem as comprehensive as the one my first post linked to. Doesn't discuss embed, for instance, nor does it mention anything about intranet's vs. internet's. Maybe Sun decided between 1.5.0 and 1.6.0 that the whole internet / intranet distinction was pointless, but if so, that'd be nice to know.
Besides, sometimes hearing people explain it in different ways helps. Whether or not it'd help here is something I can't say until I've heard other explanations (if there are any to be had).
(I'm yawnmoth, btw - I was logged out when I tried to make this post so I tried to login with 'yawnmoth' as my username and it asked me for a new username? maybe my 'yawnmoth' username is actually my email address?)

Java vulnerability on Internet Explorer?

I've noticed that when I try to enter a certain site with Internet Explorer a Java written virus tries to attack me. Does anyone know anything about this? How can I fix it?

The first thing that the antivirus locates is a .exe. If I turn on Emergency Block right away the JVM doesn't start. However, if I don't turn on Emergency Block right away, the JVM starts and the antivirus detects a .class file. After that, the PC freezes for a while and I reset it (I won't wait to see what happens). When I restart, I find a folder named Sun with a lot of .class files inside.

Java swing on Internet Explorer Urgent

hello,
I have simple applet. Which can be viewed on appletviewer , But if I try to view in Internet Explorer ,it gives nothing.
Plz help Me.

Go to this page to find out what version of Java your browser is using:
http://javatester.org/version.html
If it is not JDK 1.2 or higher, it doesn't support Swing or a whole lot of other really useful features that have been in Java for years. Blame Microsoft for that.
Then go and download the Sun Java plugin so that your browser will be using an up-to-date Java implementation.

Java runtime problem Internet Sales

I am getting a runtime error in the SAP Internet Sales Shop Management tool when I try to create a new shop. I am quite sure my problem is java related because the SAP generated webform fails too fast. There doesn't seem to be any time for abap processing.
Has anyone experienced this before. How can I find out where the problem is?
Thanks very much,

Hi Pankaj,
you can try with the first patch of the SP 9 - for example try the file ISAWAC40SP09_0-10002109.SAR. Extract the file using the sapcar program and search for docs.sar file where the documents are.

Java Applications and Internet

Is there a way to make a java application able to upload or download files from a secure internet site?
i.e. I want o make a program that when I push a button, it uploads my documents to www.boneheadfiles.com (not a real site).

Then you need to make a dos console-based ftp application. Actually I've never done this per se but it isn't so hard;-
1. Make a connection
2. open a socket on port 21
3. write bytes & send it
4. Write another class to receive bytes
Do a search here and in the Java Form for ftp and you'll get lots of source code samples

Java with the internet

I didn't know if there was a way to create a java application that went to an internet site and typed into a textfield my username and password, and logged in. Is there any way to do that???
Thanks.

On the web, forms are submitted either with the GET method or with the POST method.
It is certainly possible if the site use the GET method to send the data.
The GET method pusts the data directly in the URL. That means that you can directly make a link with the appropriate fields and values filled.
However, all people with half a brain use the POST method in this
case.
It's more difficult with the POST method. But all you have to do is to send a POST request to the site (using a socket perhaps ?) with the appropriate headers.
Learn how POST request are structured in the HTTP specification.
It's even possible that existing software tools allow you to do that.

Java keeps closing internet

Whenever I try to play a game or visit a site that uses Java, it closes my internet. Every time. I have no idea what is wrong with it. Anyone know what to do about this?

Nope. The page closes right as something that runs on JAVA comes up.

Connecting Java programs to Internet

How do we allow two users running the same Java program communicate over the internet via the same Java program ??
For instance, if I were to make a two player game like tic-tac-toe, how would I make the changes one player makes appear over the computer of other ?
[PS - About the tic tac toe game, is there an open source available anywhere ? ]

For instance, if I were to make a two player game like tic-tac-toe, how would I make the changes one player makes appear over the computer of other ?There are many ways to do that... Probably the simplest is a pier-to-pier socket setup. You just have to define your own simple "top-level network protocol".
>
[PS - About the tic tac toe game, is there an open source available anywhere ? ]Why of course there is. Is google broken or something? Hint: Keep looking past the first page... and/or search these forums. Look right, see the search box?
If you wanted to get really funky I suppose you could even do it pure ECMA version using ajax'y sockets to talk page-to-page... but that's not java, and you asked about java.
So... Start here... go through the Sun tutorial... and then I suggest you dig for IBM's chat-app tutorial (sign up for it, it's worth it)... then you need to write a single swing tic-tac-toe (again search these forums, or google it)... then you get to figure out how to merge in the comms-stuff with the swing stuff... which will almost inevitably lead you to MVC (google again) to "drive" the UI's from the protocol.

Hi All,
I have recently started working on java,i need to a create a plugin which can launch any file type(say any file which draws a cube with some extension .abc).Where should i start my work from.What do i need to do first.Please help me out coz it is very important for my project work.
Any suggestions would be much appreciated.
Regards,
Deepti.

Hi Viravan,
I signed my applet as u said but for some reason the browser is not recognising the cert.The applet is reading a wrl file from my local C drive.I'm creating a plugin to show this applet in the browser window.this is all i have to do.i guess u will have an idea by looking at this program of mine.
Curves.wrl is the file which i'm reading from the Cdrive.
i even changed my policy file but in vain.

Java on 770 Internet Tablet

I just received a Nokia 770 and when I go to certain websites (i.e. Pogo.com) it will tell me that Java is not installed on my system and will not open a window to access the games.
How do I get Java installed on my 770 or can I?
Thank you.

There is no Java implementation for the 770 (without using a handheld PC, I don't know of any handheld devices with "full" Java - J2SE - support required by some web sites).

Java not working in Internet Explorer

I normally use another browser (Google Chrome) but need to use Internet Explorer for a particular online banking service. This service requires a Java applet.
I have the current Java environment (as at 21.3.12), SE 6 Update 31.
Java works in Chrome but does not work in IE8 or IE9.
I have un-installed and re-installed Java several times, tried going back to IE8, turned off ActiveX filtering, confirmed Java scripting is on, checked add-ins are managed correctly and so on and so on, without success. Given Java works it is not a Java
issue but must be an IE issue.
Are there any additional steps or diagnostics I can run to try to identify the problem as I need this to be resolved for the purposes of running my business.
Many thanks!

Hi guys.
I'm having an issue like this and none of the solutions above helped me.
I'm trying to open a specific web page that is not working with Java only on Internet Explorer (7, 8 nor 9). If I try to open in Google Chrome or Firefox it goes fine.
I've tried various versions of Java and all my tries were done both on Windows XP Professional and Windows 7 Professional.
The weird thing is that when I test it through Java webpage or some other page, it goes fine. It is not working only for this specific webpage.
This is the webpage:
http://iweb03ds.magnaclosures.com/stconf.nsf/meeting/mid3FC5EBB1D59C830685257A2900420436
It is a meeting webpage for our company to present their work to our clients and suppliers. I've also followed their own step-by-step advises, but no good either.
Could anyone help me on that?
