Guidelines to create Instant Messaging Program.
Good day everyone who is reading this.
Simply speaking, I would like to HardCode a simple, Instant Messaging Program for my School Project.
By simple, it just means a plain messaging software that works like MSN, where I can log in and see the contacts available.
When engage in Contact, I can send messages and small-sized files to the other entity.
So the question I would like to ask is, I have no leads on how to start on this. Therefore, I hope the experts here would suggest some GuideLines or Tutorials I needed to learn before starting this project.
Also, are Java RMI and Multi-Threading essential factors to create this program?
[_So, You Need to Write a Program but Don't Know How to Start_|http://home.earthlink.net/~patricia_shanahan/beginner.html]
RMI is just one way to approach this, you could also use other protocols.
Multi-Threading will probably come into it at one point. You might be able to avoid it, but that would probably become even more complex.
Generally, start with the [Custom Networking|http://java.sun.com/docs/books/tutorial/networking/index.html] and/or RMI tutorials.

Command Line Instant Messaging Program Developing Help
Does anybody know a good tutorial for developing instant messaging programs?Or has anybody developed a similiar program like MIRC using java?
If u have any ideas please help me.There are quite a few java implementations for irc out there. Take a peek at sourceforge.net and search for Java IRC, that should get you started. This is a quite complex matter, so please get a first overview and get back with more detailed questions.

Instant Message User Names have Codepage Problems
Hi,
We're using NW 70 SPS13 Portal System and using RTC. But when we use Instant Message program, users Name and Surname displayed normally, but have character problems. Here we're using Turkish Characters in Name/Surname's and they're displayed incorrect on chat windows although they're displayed correct on LaunchPad.We too (with russian characters).
Our typing with SAP:
We: We have characters problem with displaying user Names in chat window (NW 70 SPS12 Portal System)
SAP: Can you please check if the issue is reproducible when the user has no
special characters in his name ? You can simply create a new user with no special characters and check
this.
We: No, when we using english characters in user Name/Surname, they displays properly in the chat window.
SAP: Please check if the following Java Arguments are included in SAPJ2EE. If not, please add the following Java Arguments to your server and restart the Server after that. Edit the services.ini (located under ..:\SAP_J2EEngine6.20\configtool) or start the SAPJ2EE Application Server > Tools > Config Tool.
o -Dhtmlb.useUTF8=X
o -Dfile.encoding=ISO-8859-1
If you want to support non-latin characters in Filesystem based Repositories you have to set the same encoding as used for the UNIX Filesystem (For Example if you want to support special charaters such as 'umlaute' and japanese characters you can use):
o -Dfile.encoding=UTF8
o -Dcm.decode=X
We: Thanks for your reply but problem remains. Now i have added following java parameters to my server node:
-Dhtmlb.useUTF8=X
-Dfile.encoding=UTF8
and view of characters in user Name/Surname has changed to some trash.

How to iChat / Instant Message without Internet?
I need to be able for two computers to talk to each other via a instant messaging program weather it be AIM / iChat / Third Party software but without a internet connection.
I know there are programs that work for the PC that are called LAN Messengers or LAN Chat, but I can't seem to find one that works with a OSX.
Any help is greatly appreciated.
Thanks!If on the same network use Bonjour.

I can write an instant message program, but my only hurdle is...how do I get the message to pop up automatically to the online user?
I'm not at all familiar with ajax, could you give me an example of how to do that?
User table is users, checking user_name and if message = 1. Thanks! -
.. I am currently in a class for java programming, and the such, so I have an understanding of the outline of java, and a desent amount of its workings... this is my second year with it, and my third class.
ok... to my point. I want to write an instant message program the I can use for 2 people... as in me and my brother, on the same network.
we are in the same house, but I wanted to experiment with it, and see what I can get it to do and things of that nature.
I was looking at the knock knock client server app, to see what ind of things it implimented, and method calls and the such.
What would I need exactly to send a message from one computer to the next, and vice versa.
I know I need to open a socket, and have the client server listen for a connection. but how do I get the message to send to it?The both alternates you are thinking over are fine. But the later one may cause some performance and memory issues.
If you want to go with the first alternate, I suggest you to develope your owen server using ServerSocket and use your own protocol for communication between client and server over the sockets. Because using HTTP protocol will slow down your entire application. It adds overhead because each request passes through the servlet container. -
Hi, I am curently in my final year of my Computer Science degree and have decided to develop a J2me instant messaging program for my final year project.
My problem is that i am unsure of how to implement the message exchange between phones, as to recieve asynchronously the connection must be held open, is this possible with http posts and gets?
And are servlets the best solution for the server tier?
My ideal solution would be MIDP 1.0 compatible as i would like to deploy it onto a mobile for demonstration.
Any Ideas of how to go about this?I've done this. Hmm, ok to be honest it's on early stage now, but working. I haven't yet released it for the public but the time will come.. soon but not yet :)
If you want to assure most compantibility with phones, you don't want to use socket connections. Socket connections do not require midp2 but are rare on midp1 phones. I did this by using basic httpConnection. You want to think through if you would really be willing to chat on realtime with your phone's crappy keypad ;) In my case I thought to have just a cheap alternative to sms. You can use a thread to invoke polling every once in a while to check if there are any new messages waiting on the server. Polling period is up to you, but if you want realtime chatting it has to be less than 10 seconds which also makes it a bit more complex so you won't mess the stuff with the threading. On Nokia S60 there is an awful ArrayIndexOutOfBounds bug waiting for you with the commands :D -

Service desk error creating support message "help- create support message"
Hi
I'm customizing SM 7.0 SP Stack 15 service desk scenario. I'm in a VAR SAP, so It's a mandatory scenario.
I've done all basic settings from General Settings, Connection to SAP, Online Documentation, ...,
Business Partners, iBase, Basic BC-Sets for Configuration, Number Ranges. After them , for Scenario-Specific Settings-> Service Desk->Service Provider I've done all these steps. At SAP System Solution Manager, I've created solutions at dswp transaction and EW Alert are centralized these steps works. Transaction notif_create works and iBase are well mantained.
The problem is when I try create a support message from satellite SAP system. I logged With a SAP user which is BP, key user and has authorizations in a satellite system and I choose help->create support message, so a pop-up appears and I fill the fields, and I press button (Save/Send). An error appears:
Error in Local Message System: Access via 'NULL' object reference not possible. Message was Not Created
In order solve the error I review:
- The satellite SAP system is at the iBase installed components.
- I've Assign Number Range for ABA notifications at SLF1 transaction.
- I've Checked number range for Service Desk Message at SLFN transaction.
- I've configured ABA Message transaction DNO_CUST01, transaction DNO_CUST04
- (satellite system) Transaction sm30, table BCOS_CUST:
Appl. + Dest. + +
OSS_MSG W SM_SMGCLNT010_BACK CUST620 1.0
TST_CUS 0120009939
RFC SM_SMGCLNT010_BACK works, SM recollects EW Alert from this satellite system
- (satellite system) I logged with a SAP user with these roles:
SAP_SUPPDESK_CREATE
SAP_BC_CUS_CUSTOMIZER according SAP NOTE 834534
SAP_BC_CUS_ADMIN according SAP NOTE 834534
SAP_SV_FDB_NOTIF_BC_CREATE
SAP_SV_FDB_NOTIF_BC_ADMIN
All these roles are mantained.
- I've review SAP Notes 834534, 864195, 621927(I haven't applied this SAP Note because it's older)
Please could you help me?
Thanks and Regards
RaulHi,
When I try create a SAP message via help->create suuport message, I get the same error so I run help->create support message in a satellite system so I run help->create support message in Solution Manager
system. Also, a dump is generated in Solution Manager when I try create support message or from satellite or from solution manager.
========================================================================
Runtime Errors OBJECTS_OBJREF_NOT_ASSIGNED
Date and Time 10.07.2008 10:17:26
Short text
Access via 'NULL' object reference not possible.
What happened?
Error in the ABAP Application Program
The current ABAP program "CL_BOR_SERVICE_PPF============CP" had to be
terminated because it has
come across a statement that unfortunately cannot be executed.
Error analysis
You attempted to use a 'NULL' object reference (points to 'nothing')
access a component (variable: " ").
An object reference must point to an object (an instance of a class)
before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the
CLEAR statement.
How to correct the error
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"OBJECTS_OBJREF_NOT_ASSIGNED" " "
"CL_BOR_SERVICE_PPF============CP" or "CL_BOR_SERVICE_PPF============CM004"
"PROFILE_CONTAINS_PARTNERDEP"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
Information on where terminated
Termination occurred in the ABAP program "CL_BOR_SERVICE_PPF============CP" -
in "PROFILE_CONTAINS_PARTNERDEP".
The main program was "SAPMSSY1 ".
In the source code you have the termination point in line 41
of the (Include) program "CL_BOR_SERVICE_PPF============CM004".

Thoughts are to allow groups of individuals mobile numbers to be shared across larger organizations, from within a PDF document, that the mobile numbers would be clickable, and open up a Text or instant messaging application on either the computer, tablet, or smart phone, for instant communication.

NehaHi Nicole,
Thank you very much for the reply. You are correct, but I checked the SICF set up was ok. Currently we are not using the workflow. Recruiter's role assignment was also proper.
This problem was related to business partner number range assignment for internal/external candidates, since it was not creating new business partner. It is ok now.

With SP16-17 we can't create support message from satellite system anymore
hello,
We have implemented the support package 16 and 17 SAPKITL427 in solution manager last week-end and since then all satellite systems can not create support message anymore.
The process is perfectly working in solman itself and we don't think we have thus a process customizing issue here but who knows...
The key user creates the message with the help -> create support message
and when he saves it (clicking the mailbox button) he gets the following error
Error in Local Message System: Function not available Message was Not
Created
In fact the error Message is BCOS088
We debugged the function BCOS_CREATE_MSG and we found out that the function
DNO_OW_CREATE_NOTIFICATION is returning error code 1.
We checked out RFC connection and it looks ok
There is no dumps in ST22, no error in SLG1 in both system...a nightmare
The notification SLF1 is created in solman but the status field of the notification is empty and it looks that the record is somehow corrupted because you can't modify it with dnotifwl.
Due to the fact that the notification is not correctly created the support message is also not created.
SAP and our solman consultant are working on it since 2 days but don't have a clue. Maybe some program where no regenerated correctly ?
If you would have any idea in which direction to look, i would greatly appreciate
thanks a lot

itunes install error message - program not found ...x64/difxinst64.exe
no problems with ITunes on Dell Inspiron Windows 7 until yesterday. ITunes version 11.0.2. iphone won't connect stating required software is not installed. uninstall and install 64 bit version of iTunes. I have 64 bit version already. I have uninstalled and reinstalled 5 times already. When re-installing ITunes get error message c:\programdata\34be82c4-e596-4e99-a191-52c6199ebf6\x64\difxinst64.exe. file does not have a program associated with it for performing this action. please install or create an association in the Default Programs control panel. iTunes install continues after the difxinst64.exe error message but then get the iphone cannot be used error message again. therefore, I can't sync my iphone with iTunes until I figure this out.
can't win for losing. had iTunes on my windows 7 laptop for 4 years. first time I've ever encountered this.I am a PC Tech and had a customer with this issue. Ran across this post in my search and ended up finding the solution on my own. The problem isn't with the iTunes software but the installer for the GEARAspi drivers. Really the issues is with the file type asssociations in the windows registry. On the system I was working on the HKCR key for .exe should point to the exefile key but pointed to nothing. To fix it create a new txt document and paste the following in (only paste what is in between the [code][/code] tags):
[code]
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.exe]
@="exefile"
"Content Type"="application/x-msdownload"
[HKEY_CLASSES_ROOT\.exe\PersistentHandler]
@="{098f2470-bae0-11cd-b579-08002b30bfeb}"
[/code]
Now change the extension from .txt to .reg. Then right click and select merge. iTunes should now install properly.
