Hi, I love Java Chat.

Hi, I'm interested in learning more about java chat. How it works and how to do all the special functions. It seems really popular and I feel like a novice because I only know how to type and log in.
Oh, pardon me, I'm Eanus. I like fishing, history and such.
Nice you meet you.

Hi,
I'm nice to meet you.
Sorry to say but this is a programming forum, and not a forum where you can ask about how you use a certain program.
Good luck
Kaj

Java Chat applet won't send messages

So i got a brand new MacBook Air yesterday with Mac OS X 10.8.2 and installed Java 7 Update 9 from Oracle.
When using Safari 6 i run into a problem with a browser based Java chat applet.
First of all: Java and Javascript are actibated in Safari.
So I go to the chat's website and start the chat.
Java works fine at first and the chat starts.
People can send me private messages and i can type in a reply.
However I cannot send these replies. Neither in the private messages (applet) nor in the main chat (browser).
Any idea how to fix this issue?
(BTW: Java 7 was the first Java ever installed on my Air, so no going back to Apples Java 6)

And Java 7 Update 10 did not solve the problem either.
Can anybody offer any ideas for a solution?
Help would be much appreciated.

Java chat console not appearing

hi there. please help. i am trying to use java chat console but cannot get it to work. i have tried everthing that the chat site tech asks of me, but still no luck. anyone else had this problem PLEASE let me know how u solved it.
many thanks

This isn't really a Java programming question... it's more a "something's disconfigured on someone's computer" question... but, just for fun, here are the things you need to check:
Does your browser have a Java plug-in installed? Is the version of the Java plug-in compatible with the Java chat version the server is using? Do you have Java enabled in your browser? Do you have this problem with other Java applets from other sites, or only this one?
I'd recommend upgrading your JVM (or downgrading it, if the site is really that broken), checking your browser settings, and possibly testing with another browser.
Sincerely,
Dylan

Java Chat Servers???

I hope this isn't an inappropriate query for this forum. I'm looking for a Java Chat Server and was told that Sun/Java provides a free, open source implementation but haven't been able to find it. I've also looked at some of the commercial offerings such as Volano and RealChat. Would anyone like to offer advice on the best options?
Thanks for any help.

I've coded my own very basic version but it would be
much cheaper for my company to buy one than to try
and do a full-blown, commercial-grade, fully
de-bugged implementation from scratch or demos, for
me at least ;-)I'm sure it would be cheaper. I'm sure that chat servers are extremely common, too. By the way, where does Java come into your picture? I don't see any benefit to having a chat server that happened to be written in Java.

Java Chat, server/client*x

Hey,
I'm trying to make a chat and I've made the server and client, and the server can accept several clients. Only; they communicate client-server, and not client-server-client (if you get what I mean) like I want them to, pretty obviously, since its a chat. I'm still very new to this, heres my code anyhow:

}I want to make it graphical too, but I want to make it work like it should, before i tackle trying Swing out. This code isn't completely complete yet, as you can see. It doesn't handle the clients messages correctly yet.
What I want to know is how i should send a message from a client to all the other Sockets on the server.

It compiles, but it gives an error when the client connects.

Java chat closing when the page looses focus

I just got a mac about two weeks ago, switching from being a lifelong NT/2000/XP user. So far I love it, but there is one thing really bugging me.
I am a regular in an online chat for a radio station I listen too. They don't use irc, just some java based chat software. Whenever I switch to another safari window or tab, the chat room's connection seems to close, and I have to log back in.
Anyone know what is causing this, or how to fix it?

Still need help with this issue!

Trying to produce a java chat server

Would like produce a working client/server chat system, as basic as possible but able to listen and talk to each other. Any chat servers how-to examples I've come across never seem to work.
Would like to understand why applets don't work when I open the web page but do work when I view using the appletviewer. I use Internet Explorer 4 i think, java version 1.3.0_02
would you understand at least part of this error which appears when I run a chat server

Java chat issues in Safari & Firefox

Hello everyone,
I've been a Mac person for a long time, and my whole life runs through an apple product of some kind, and while I was an apple sales rep for awhile, I'm not the most tech guy on the back end. Here's what's happened. I convinced my mother in Canada that she needed to get a mac, as she was having a **** of a time with her PC. After years of sitting on the fence, she jumped in with a mac mini and I was so proud. Trouble is, she hates it.
A very big part of what she uses the computer for is online chatting in her support groups, they all use Java, and she tells me that what's happening is that she won't see a message for a few minutes and then a hundred of them will stream in all at once. These lags or delays can't be a result of the connection, as when I was there in summer her bandwidth was huge, there is clearly just some issue with Java's chat and safari. I tried to get her to use Firefox and she says it was better, but is having the same problem.
She's frustrated to the point where she's talking about pulling the PC out of the Ewaste pile in the garage and hooking it back up.
I mean how hard can it be to get a 62 year old women on a chat page?
I'm in australia, and she's back in canada, but I can get any info anyone might need. These groups are support groups for parents who have lost children, her having lost my little brother at 19 only 3 years ago. They're very important to her, and I'd really appreicate if someone could help me get them back for her.
Thank you

HI,
It would help if you posted back and told us which Mac she has, which Mac OS X it's running, and which online chat software this is. iChat ?? We need more details.
What type of internet connection is she using?
*"and she tells me that what's happening is that she won't see a message for a few minutes and then a hundred of them will stream in all at once."*
That sounds more like her internet connection speed more than a Java issue.
If she has broadband, have her go here and see what her upload and download speeds are.

Broadband download should be approx. 16mb/s
Upload approx. 11mb/s
What happens when she's using Safari?
