While open socket,why JDK1.4.2 open additional port byt JDK 1.4.1 do not?

Dear All:
I am programming swing client project
I found an interesting difference betwen JDK1.4.1 & JDK1.4.2
While open socket to server ,jdk1.4.2 stub in server will open random port to the "request" client
(see below)
==============================
client ----------port:7001---------->ejb server JDK1.4.2
<--------port : ? (random)--
=================================
but in jdk1.4.1 ,only
====================================
client ----------port:7001---------->ejb server JDK1.4.1
======================================
This phenomenon ,confuesed me these days.Have any parameter to fix the socket connection rule for the latter JDK version?
Best Regards
john

There's not enough info there: there should be a local and a remote port number per connection; but it's not possible the way you describe it. It's probably another connection from the client to the server, maybe for DGC?

When opening numbers why do all spreadsheets open

upon opening numbers, all of my saved numbers files open. why is that happening and how do i stop it

If you close all documents before quitting Numbers or Pages, you won't have them reopening when you launch the app again. You can quickly close all open windows in an application by typing ⌘ ⌥ W (Command + Option + W) or hold down the Option/alt key while clicking the red close button.
Other things you can do to turn off this resume feature:
In Moutain Lion you can set System Preferences > General to close windows when quitting an application.
Try Mountain Tweaks. The option to turn off resume is at the bottom of the left-hand column under Lion.

On VMM managed cluster hosts, I can't figure out why most of my hosts answer port 5900 and the others 2179, but not both

Below, you see a netcat list of my hosts. Most are answering port 5900, but not 2179. The list on the bottom is answering 2179, but not 5900. I need to know for 3 reason why this is, (1) to setup our enterprise firewall, (2) for port health
monitoring of our hosts, and (3) just what is going on. I thought that 2179 should be open on all hosts, and that 5900 was only used in legacy cases (at least from what I read from googling around). Why aren't all of my hosts answering 2179?
My hosts are all Server 2008 R2 Datacenter SP1 64-bit. We have a mix of VMs with Server 2008 R2, Win7, and RHEL6, all 64-bit.

Brian,
This is specifically related to Hyper-V hosts, where the following ports may be used by the VMM to communicate to each host:
VMConnect (RDP) to Hyper-V hosts 2179
VMRC connection to Virtual Server host 5900
These ports are outlined here...
technet.microsoft.com/en-us/library/cc764268.aspx
I am not running independent VNC servers on my hosts. They are VMRC ports. My confusion is why some of my hosts are only answering 2179, while the others are only answering 5900, but not both ports on all hosts (or for that matter just 2179 on
all hosts).

Why can't I open a FCE project file that I have saved? (It now says ZERO kb

Hello...
I have just started working on a project in Final Cut Express - I render, save, and close out of FCE - but, when I go back to FCE, the project I was working on does not open.
Why can't I open a project file that I have saved?
Here was my process in a nutshell:
~ When I opened FCE, I went the System Preferences and set the Scratch Disks to a folder on my external hard drive.
~Then, I went to File - New Project - worked on the project for a while (including creating bins, importing images and video, and creating a sequence.
~I saved the project file to the same folder that I set my Scratch Disks to.
as often throughout this process.)
~When I was done, I saved again andd closed FCE.
~Then, soon after, I opened FCE again and my project did not open automatically.
~So, I clicked File - Open Recent - browsed to and chose the project file name and FCE gave me a "Unable to open file" message.
~When I check to see if the project file actually saved to my external hard drive, the name appears, but it says the file size is ZERO kb.
I have done this twice with the same unfortunate result. What am I doing wrong? I have worked on FCE on this same computer before, setting the Scratch Disks the same way, and I did not have this problem.
Please help. Thank you so much for your feedback.
...Rae

Are you sure you are trying to open the project file you actually saved ?
Try using Spotlight to search for your project file name. I might be wrong, but I guess you try to open an empty copy while your real project file (what you saved) is somewhere else in either your startup disk (Documents folder ?) or the external drive. If so do not use Open Recent in FCE but simply double click the "real" project file.

Why does reader freeze while opening some pdf files and others open instantaneously?

I use pdf files created from CamScanner and shared from DropBox. In DropBox, many times (over 50%) while opening the PDF the process freezes and the error message is Adobe Reader is not responding. If you close the program, and re-open the file, it opens fine. I have saved these files to my computer and the same issue occurs. The files are 100-500kb, so I do not think size is the issue. I have reinstalled Reader (11.1.10) and there is no improvement.

This appears to have reduced the time to load a document. Thanks Jimb From: Anubha Goel <[email protected]>

Why can't I open email pdf ad administrator, while computer user can?

I can't ope email pdf file as administrator, while computer user can?

When I opened outlook yesterday, there was a 7 mb pdf I needed to review. I moved my cursor over the pdf. A description window opened detailing the pdf specs. However, Double clicking did not open the pdf. Right clicking did not open a drop down options window. I had the file sent to me three times under different names but the pdf would not open. Opening up older emails I discovered that I could no longer open any pdf from outlook.
You can go to top highlight attachment and then save attachment.
But what changed and how to I change it back to be able to open pdf from outlook when reviewing email.

Too many open socket connections causing ColdFusion to crash?

I’m currently working on an e-commerce site which sends and receives information to/from the client’s order management system via XML over a TCP/IP socket. It uses a very old java-based custom tag called CFX_JSOCKET (which appears to have been written in 2002) to open the socket, send the data, and get the response. The code that calls the custom tag and sends/receives data from the OMS pre-dates my working on the site, but its always worked, so I haven’t paid it much attention.
Back in the summer of 2009 we started experiencing issues with ColdFusion (v.7 on Window 2003 at the time) locking up on a more and more frequent basis, until it ultimately became a daily issue. After extensive research we narrowed the issue down to the communication between the web server and our client’s order management server. It seemed the issue with ColdFusion hanging was either related to there being too many connections open, or to these connections hanging and resulting in dead threads. This an educated guess based on a blog post I’d seen online, not actual monitoring of either CF or the TCP/IP connections. As soon as we dialed back the timeout on the CFX_JSOCKET tag from 20 seconds to 10, the issue disappeared, so we left it at that and moved on.
Fast forward to this January. The site is hosted at a new location, on a 64-bit Windows 2008 box running ColdFusion 9. Over the years traffic on the site has continued to grow. The nature of the clients business means that August and January are their business times of the year (back to school for college kids) and in January ColdFusion once again started locking up on an almost-daily basis.
One significant difference is that the address cleansing software that previously ran on the box and was used to verify shipping addresses is not available for 64-bit, so when we moved to the new server last summer, that task was moved to the client’s order management software and handled via XML like all other interaction with that system. However, while most XML calls to that server (order input, inventory check, etc) take under a second to complete, the address cleansing call regularly takes over 5 seconds to return data, and frequently times out.
Once we eliminated the address cleansing call from the checkout process, ColdFusion once again stopped locking up regularly. So it appears that once again it’s the communication between the web server and the order management server that’s causing problems. We currently have that address cleansing call disabled on the web site in order to keep ColdFusion from crashing, but that’s not a long term solution.
We don’t have, nor can I find online, the source code for the CFX_JSOCKET custom tag, so I decided I’d write some CF code utilizing the java methods to open the socket, send the data, get the response, and close the connection. My test code is working fine (under no load). However, in trying to troubleshoot an issue I had with it, I started monitoring the TCP/IP connections using TCPView. And I noticed that all the connections to the order management server, whether opened via the custom tag or my new code, remain open in either a TIME_WAIT or FIN_WAIT2 status for well over 2 minutes, even though I know for a fact that my new code is definitely closing the connection from the web server side.
They do all close eventually, but I’m wondering 1. Why they’re remaining open that long; 2. Is that normal; and 3. If all these connections remaining open could be what’s causing ColdFusion to choke.
Does this sound plausible? If so, does anyone have any suggestions/recommendations about how to fix it? My research seems to indicate this might be a matter of the order management system not closing the connection on its end, but I’m in way over my head, and before I go to client and tell them it’s their OMS causing the issue, I need to feel a little more confident that I’m on the right track.
Any help or advice would be very greatly appreciated. And thanks for taking the time to read through my long-winded explanation of the problem.
Set-up details:
ColdFusion Version: 9,0,0,251028 Standard
Operating System: Windows Server 2008
Java Version: 1.6.0_14
Java VM Name: Java HotSpot(TM) 64-Bit Server VM
Java VM Version: 14.0-b16
Thanks,
Laurie

Hi Laurie,
Not aware of custom tag called CFX_JSOCKET. I guess the process you described very well is consuming a resource then you are getting a problem. Trick is what parameter to adjust. Perhaps you are running out of one the threads in CFadmin > Server Settings > Request Tuning.
I expect if you enable CF Metrics logging where you can log the threads and other resources then you can find out which parameter needs adjusting. Let me know if you want some details on enabling CF Metrics. Perhaps others will have much better idea than me and help without the overhead of logging.
The other interesting thing is you are using CF9.0.0. Do you have some reasons for not being on updater1 CF9.0.1?
HTH, Carl.
PS I posted before however seems to have gone, just hope does not come back and then I have posted twice.

Too man open sockets?

After running tests on weblogic server 5.1.0, sp6 for a few days, we noticed
that the number of open sockets for the Java VM slowly creeped up to 472.
This test was run with 75 simulated users with
weblogic.system.executeThreadCount=15
The question is: why are there so many open sockets? We did have a JDBC
connection pool of size 100, but that does not account for the 472 open
sockets.
Any ideas?

If you don't kill WL properly it will leave all of those extra java processes running. try using this to shutdown your server:
$JAVA_HOME/java -cp ./classes/boot:./classes:./lib/weblogicaux.jar weblogic.Admin t3://localhost:(WL PORT) SHUTDOWN system password
this won't kill the ones that have been stopped incorrectly already but it will kill the ones on the current WL instance.
To make sure this is the problem just stop the server the way you have been and if the java proceses are still there then it was the way you were shutting down.
Hope this helps

Unable to open socket in MIDlet

I am using jdk1.4.2_012, CLDC1.4 & MIDP2.0.
I have written the MIDlet in which I want to open socket on localhost. But it is not opening the socket. what is the problem? Code module is given below:
private static String url = "socket://127.0.0.1:8100";
StreamConnection conn = (StreamConnection)Connector.open(url);
Can anybody help me out in this scenario?

Hi,
to check if it works;
If your app doens�t need a well-known (registered) port-number, use dynamic port-asignment and omit the IP-address of local host, as following:
private static url = "socket://";
Why StreamConnection and not SoketConnection as the data- type of returend object by open(url) - method?!
Note there are big differende between these 2 types connection. Socket is higher level connection than StreamConnection. It has the implementation of TCP trasport-protocol inside.
Bye,
Asghar

DirectoryService[67]: socket(PF_ROUTE) failed: Too many open files

Hello!
On MacOSX 10.4.10 which is an OD master, my log are filed with this:
DirectoryService[67]: socket(PF_ROUTE) failed: Too many open files
It happens at exactly every hours 44 minutes 18 seconds 161 times. At the same time, it makes a lot dns request for "kerberos-master.udp.XXXXXXXXX.COM IN SRV +"
The server works fine, but there's probably a cronjob that go crazy and i would like to know why it's happening.
Thanks a lot!
Fred

Hi,
Cause might The server got an exception while trying to accept client connections. It will try to backoff to aid recovery.
The OS limit for the number of open file descriptor (FD limit) needs to be increased. Tune OS parameters that might help the server to accept more client connections (e.g. TCP accept back log).

I have a brand new macbook pro 15" with latest Lion.Can anyone tell me why, when I open word or preview etc that multiple files open?For eg if I open a word doc, the last 1-3 docs that I have worked on all open. why?

I have a brand new macbook pro 15" with latest Lion. Can anyone tell me why, when I open word or preview etc that multiple files open?For eg if I open a word doc, the last 1-3 docs that I have worked previously on all open. Can anyone tell me why?

You have a choice as to whether or not applications in Lion like Word or Preview (or even Safari) save and re-open previous documents or windows... just hold down the option key while quitting a program and when you re-open it you won't get the previous documents or windows when you re-open the application. You can see this by selecting the open program in the menu bar and when holding down the option key the quit function will change to quit and discard open windows. This feature in Lion is referred to as "Resume" and is great if you want to restart an app and return to what you're doing (for example in Safari re-opening existing windows and tabs from your previous session). You still have the option to close individual windows within an app before quitting and they will not re-open when the app is launched again.
This Resume function is not related to saving your work (a word or text document for example). This is handled by Lion's "Auto-Save" and "Versions" functions. See http://www.apple.com/ca/macosx/whats-new/auto-save.html
Hopefully this is the complete answer you're looking for.

Why does illustartor CC open then crashes and i get a message saying windows don't know the prob?

why does illustartor CC open then crashes and i get a message saying windows does not know what the problem is. everytime i open it, Now i know it works on my computer becuase i've used illustartor plenty of times on my current desktop but ever since today its been acting wierd and work so i've unistalling and reinstalling but still nothing works then i tried installing on another hardrive still did not work and i cleaned out my registryies, optimized my disk, and cleaned temp files tooo so i just do not know what went wrong and i really need help i have class assignments that i have to get done in illustartor so if anyone can help me and let me know what the problem is and what i have to do i would really apreciate it.

Hi J,
- Do you see an AICC splash screen? If yes then could you please let us know where exactly it crashes i.e. while loading which plugin or font?
- Do you have any 3rd party plugins installed? Can you please remove those (do take a backup of them) and see if AI launches fine? This way you would be able to find the plugin creating the problem.
- Did you install any OS or Ai update after which it started showing the problem?
- Please check if you have all the Verdana family fonts installed.
Let me know if any of these work.
Thanks,
Dhirendra

I used iphone 3gs iOS 6.1.6 why i can't open an application camera 360 ultimate

I used iphone 3gs iOS 6.1.6 why i can't open an application camera 360 in my iphone

Hello Kunmon,
The following article provides some useful troubleshooting that can help get your iPhone's camera working correctly.
Camera isn't functioning or has undesired image quality
If the screen shows a closed lens or black image, force quit the Camera app.
If you do not see the Camera app on the Home screen, try searching for it in Spotlight. If the camera does not show up in the search, check to make sure that Restrictions are not turned on by tappingSettings > General > Restrictions.
Ensure the camera lens is clean and free from any obstructions. Use a microfiber polishing cloth to clean the lens.
Cases can interfere with the camera and the flash. Try gently cleaning the lens with a clean dry cloth or removing the case if you see image or color-quality issues with photos.
Try turning iPhone off and then back on.
Tap to focus the camera on the subject. The image may pulse or briefly go in and out of focus as it adjusts.
Try to remain steady while focusing:
Still images: Remain steady while taking the picture. If you move too far in any direction, the camera automatically refocuses to the center.
Note: If you take a picture with iPhone turned sideways, it is automatically saved in landscape orientation.
Video: Adjust focus before you begin recording. You can also tap to readjust focus while recording. Exiting the Camera application while recording will stop recording and will save the video to the Camera Roll.
Note: Video-recording features are not available on original iPhone or iPhone 3G.
If your iPhone has a front and rear camera, try switching between them to verify if the issue persists on both.
My issue is still not resolved. What do I do next?
Contact Apple Support.
