Using thread and socket connection with other machines

Hi all!
we are using weblgoic 5.1 SP9 JDK1.2.2
we already using java.net.Socket and java.lang.Thread
to communication TANDEM Machine on the weblogic.
the reason why we use to socket and thread even though it is not
recommanded is that below
1. once we connect Socket, then we using until server shutdown or
connection may has the problem, so we're using thread to wait
java.io.Inputstream to read from socket.(if I using EJB, It can't
wait socket inputstream indefinetly, because it has timeout)
2. we're logging Database date sent or received with TANDEM Machine.
so we need Database Access. so we using Database Access
thru Weblogic.
3. EJB Application using (other EJB Application - send Module)
to send data to TANDEM Machine. So "Send Module" should
be implemented EJB.
but. Now I see there might be problem this framework.
so, is there some way by just using J2EE spec, to implement this kind of
framework.
wait for your great help !!
regards.

Yes i've tried interrupt method and it doesn't have any effects on the thread... it stay in connect() method...
And for the timeouts, in fact i use an API : J2SSH, to connect with SSH protocol, and the setting of connection timeouts is not implemented yet... and the default timeout is about 4 minutes...
so i don't know how to solve this problem...

Using Threads And Sockets

Hello,
I want to create a program that can send 2 or more files through the socket to the same client at the same time. Is it possible? I am trying to use threads to do this but I am not sure what to do in those threads. Should I send the socket to the thread class and create BufferedReader and DataOutputStream again in the thread?
Also should I create threads in the client-side?
Thanks

Also should I create threads in the client-side?No.
You need to send the files one at a time. While you could basically send the data interleaved, it would still only involve only one thread, one socket and one set of streams. And it would be a silly thing to do.

A730 keyboard and mouse compatibility with other machines

I would like to have a USB keyboard mouse with the machine. Unfortunately there is not an option for that with this machine. I would like to sell the k/m that comes with the machine.
What machines including ones not made my Lenovo would the k/m be compatible with?
According to the Lenovo support page for the drivers for this k/m the drivers are compatable with various Lenovo machines.
http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS031648
Does that mean the k/m are compatable with those machines?
Is a certain piece of hardware other than the k/b required for it to work? If so, is that piece of hardware available after market?

Thank you Assaf for taking the time to install the game to check to see if you got a similar problem
honestly i'm not sure its my 865PE Neo2 LS or not,it may be a software issue. I'm just guessing because that was a the biggest change in my system before I started to experiance this problem.
I have experianced this problem with the default windows drivers as well as with logitechs current Mouseware drivers, although i have not tried to install older mouseware drivers
I've had lockups with CoreCell installed as well as removed.In DirectX 8.1 as well as DirectX 9
I thought perhaps it might have been my soundcard because prior to buying that I didnt have any problems...so I removed that...but i still got the same problem (although as i type this i realize i didnt uninstall the Audigy software before i tested....hhmmm. I'll have to test that)
I have noticed it happens more often in OSP/Quake3 (a competition mod) than in plain vanilla Quake3, but it does happen in both.
One intersting thing i discovered by trying out a Belkin KB with my set up was that when i hit a certain combination of keys it would exec a chat bind i had bound to a whole other key ?!?
the combination was r + g + spacebar = keypad home
That particular problem stopped once I went back to original Keyboard. It did stick in my mind however that when playing Q3 i am hitting combinations of keys all the time and that maybe I'm hitting a combination that is problematic for my system. I have not been able to figure out what that combintion is yet (I tried for quite a while ...but was unable to find the correct combination to reproduce the problem )

Using the Bluetooth Transceiving Key with other machines

'lo
I have recently got a Bluetooth phone and I'm looking for an easy way to give my PC Bluetooth connectivity so that they can talk to each other.
I don't have an MSI motherboard in any of my machines so I'm wondering if the transceiving key (6967) would give any machine it was connected to a standard Bluetooth connection?
i.e. can I just plug it into my PC and use it to synchronize with my phone?
Any advice would be greatly appreciated.
Thanks

Can I connect my Mac (Mac OS X) with other machine (Windows OS) on same LAN using telnet in terminal? For example, telnet ip address of other machine

Can I connect my Mac (Mac OS X) with other machine (Windows OS) on same LAN using telnet in terminal?
For example, telnet <ip address of other machine>
I m a networking student and I have learned to connect 2 machines on Red hat Linux OS on same Ethernet LAN which has same subnet mask. As Mac OS X is also a linux based OS I m trying to connect my Mac with my friends windows based machine using telnet <ip address of his machine>. However, I get a message "unable to connect to remote host".
Can anyone please tell me is this the problem because of different OS or it is something different!
Please reply...it will of great help..

The machine you're trying to connect to needs a Telnet server running on it - telnetd listening on port 23 (usually).
Incidentally, Mac OS X is not a Linux based OS, it is based on BSD Unix.

Josejanko,
You don't supply much info other than your machine is old, so here is some info for you to check thru.
Before doing anything you should have a back up, preferably 2, in the event something goes wrong.
You would have to start by upgrading to Snow Leopard, you would need to buy the disk for about $20 here http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
Check the the requirements to see if your machine meets them.
You would then need to run the 10.6.8 v1.1 combo update to get it to 10.6.8 Mac OS X 10.6.8 Update Combo v1.1
You can then access the APP STORE and possibly upgrade to to further OSX.
You may have applications that will not be compatible with any thing past Snow Leopard, you can check those here Upgrading to 10.7 and above, don't forget Rosetta!
http://roaringapps.com/apps
Office 2008 will not work with anything newer than Snow Leopard for an wxample
You may be able to upgrade to Lion or MT Lion or Yosemite, depending on your machine, from the APP STORE.
OS X Lion - Technical Specifications Lion

I have an original iPad 32 why can't I connect on my home wi-fi but can connect anywhere else? No problems at home connect with other iPads and MACs.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Hi
I am experiencing wireless connection problem on 4s after ios 8.1 upgrade. The wireless icon appears showing that it's connected but webpages do not load. I have checked my internet connection with other devices and seems to be alright. what to do?
I have tried reseting the network settings and forgetting my wireless connection and re-connecting to it. I even backed up my phone on itunes and restored it, factory reseted it. Nothing seems to work.
Also after my upgrade to ios 8.1 my personal hotspot option under cellular data has disappeared.
Would you please help me out? I would really appreciate it.

Hi..
Restart your router then restart the iPhone to test.

Screen sharing option no longer works after updating to iOS Maverik. I am using AIM and so is the other person who i am trying to share my screen with. .

I am using AIM and so is the other person who i am trying to share my screen with. I log into AIM with an @aol.com account. I can request to share my screen and share the other person's screen. The window will pop up on the other computer, but after clicking accept it will go back to saying that there is a request for screen share. What should I do to fix this?

HI,
To be clear, iOS = iPhone and iPad and some iPod Touches and the Operating System they use.
Mac OS X = the Operating System Mac computers use.
Regarding the AOL account, is this actually from AOL and have the Chat/Messaging option enabled ?
Or is it a Name registered with the AIM part of AIM ?
You can have AOL as your ISP and have an email and User ID from them.
This needs to have the ability to use the name as a Chat name enabled (or at least it used to)
AIM, which actually stands for AOL Instant Messaging has it's own registration site.
Nowadays you register for a AIM email (although activating it for mail is another additional step).
It used to be that the bit before the @aim.com bit was the user name you used in Chat applications that could use AIM.
Previous to the current system you could in fact register just a Screen Name with them.
Apple (and a few US based ISPs) also have agreements with AIM that their (Apple, etc.) emails are recognised as Valid AIM Screen Names.
This means those issued by Apple ending in @mac.com, @me.com issued from the iCloud registration and @icloud.com.
(You do have to keep your password to 16 characters or less.)
From what you are saying you seem to be sure that you can see each other as On Line in your respective AIM Buddy lists ?
In Messages in both Mountain Lion and Mavericks you do not have to display the Buddy lists
(See the Window Menu plus the General Section of the Preferences to separate them)
Are you also saying that in the Video menu the option to allow Screen Shares is Enabled ?
Is it done at both ends ?
In iChat you could offer to Share your Screen with a Buddy without the option being On (they could not ask to share yours or offer theirs). I have not tested this in Messages.

Time Machine spends hours partially backing up and then fails with "Time Machine couldn't complete the backup due to a network problem." Tried suggestions I've seen on the forum.

Time Machine spends hours partially backing up and then fails with "Time Machine couldn't complete the backup due to a network problem." I've tried various suggestions I've seen on the forum but nothing has worked. TIme Machine worked fine for the last two years and just suddenly started having this problem every time. The only thing that was a little different is that the computer was off for a week while on vacation and then I added a large amount (20 GB) of photos. Now the requested backup size is 82GB, which is large, and process proceeds very slowly for 2-3 hours before failing with the message mentioned. I have more than enough available backup storage space for it. Before failing, Time Machine has backed up no more than 12GB or so of the backup. It fails during different files each time.
I've turned off the computer sleep feature, and I've checked that the NAS is set to never automatically power down. I normally backup over Wi-Fi, but I've also tried connecting to Ethernet and it still has the same problem. It's odd because I also have a MacBook Pro that is still backing up fine to the same NAS using the MacBook's Time Machine.
I am using an iMac with OS X 10.6.8 and an Iomega StorCenter ix2-200 NAS.
I have system logs that I can share if helpful. The logged messages vary a bit from run to run, but here are some messages that I've been seeing:
I always get this message near the beginning of the backup:
Event store UUIDs don't match for volume: Macintosh HD
I've gotten this messsage a number of times:

Something caused a disconnect. Can't tell from the log what it was.
I doubt it's a problem with something in OSX being damaged or corrupted, but reinstalling OSX isn't a major hassle, so might be worth a try.
To be incompatible with Snow Leopard, this NAS must be at least a couple of years old. It may be beginning to fail.
Contact the maker. See if there's an update to make it compatible with Snow Leopard. If so, that might fix it.
If not, or if that doesn't fix it, see if they have any diagnostics that will shed any light.

How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

Use user account to connect to other computer

Hi everyone,
I'm running windows 7 machine and i have a domain for study purpose so i was using file sharing option and i checked use users account to connect to other computer.
Advanced sharing and i select use user accounts and passwords to connect to other computers
so after selecting this option it logged me out and bring me to the log in option but i can not see my computer log-In name i see only remote log In name and other user option so how do i log into my
Windows 7 computer? not the remote computer
Please help i want to get back to my windows 7 computer because im logged out and i don't know how to log-In
i can only log-In the domain user account but i want to log in as windows 7 account not the domain account
please help

Perhaps the GPO prevent you from logging locally with user account that is NOT member of domain users. You should change GPO and either wait for applying it of force the update. Remember that some GPO may need restart.
