Seeking answers to some (Javamail Gmail reading) problems I'm facing!

I've this code which works ok but don't meet my requirements. It fetches the total list of messages from a Gmail account and prints the sender address, subject, in numerical order.
To print all the messages it takes up a lot of bandwidth and fails to load the target page ( if there are more than 20 messages ). Also, everything that gets printed on the target page is static.
So, my questions are:
(i) if is it possible to fetch messages for upto a desired number, can someone please tell me?
(ii) I don't get it. After so much work, this page is printing data in static manner and I don't have any idea how to read the message contents. I was hoping to read the contents like I would, in my Gmail account. So, if anyone could tell me what I'm doing wrong and what I should be doing, I would be really greateful to that person!

Answer to some of the K7N2 problems

Well I've had to go thru three weeks of mind numbing pain and 30 dollars worth of sending back RMA's. Your board is dead. Probably because you followed the manual like I did. The bluetooth connector does not go where the manuall says to plug it in. It goes where the where the manual says to plug in the front usb connector. Does MSI not even test there manuals? Needless to say after 3 weeks and $30. I will not be buying MSI again.

It maybe the board. I have the delta. The manual says to plug in the bluetooth to the pins that are closest to the amr slot. One time I got the board powered off quick enough that it didn't kill it, but at the time I wasn't sure what the problem was. I powered it on one more time with nothing connected to those pins it ran fine. I plugged the bluetooth in again and I could smell the smoke. After that when you it the power the fans spin for a second but die. Can anyone else confirm this. Am I a retard? Does it not say in the manual to plug the front usbs into the pins that are in the blue package and to plug the bluetooth ( blue connector on diag) into the pins that are directly next to the amr. There are also no directions as to how that blue plug fits on those pins. I had the end with no wires hanging off the end not plugged into anything.

JavaMail Gmail Exception when reading mails

I know that I have to use a keytool to do something that I have not understand.
Can you please give me some instructions?
Or the forementioned exception has any other solution??
Thanking you in advance

After I updated Safari to its latest version (5.1.4), some Google services stopped working!
I can't access Gmail, Reader or Docs. Their interface just won't load.

Looks like Takohashi figured out that UNchecking "Open in 32-bit mode" under "Get Info" should do the trick: https://discussions.apple.com/message/17843743#17843743.
Would be curious if this helps solve your issue, too..?

JavaMail SPI design problem

I'm planning to support a corporate proprietary mail system through JavaMail SPI extension. The problem I'm facing is the fact that the system
has such functions that don't fit well in JavaMail api (Store or the Transport). Most of the functionality can be tweaked to follow the api but in order
to fully support the underlying system some extra methods must be introduced thus 'breaking / extending' the JavaMail api. The problem with this is
that one must use concrete classes (ie casting to concrete implementation class) instead of for example Store or Transport.
The way I see it this kind of cripples the abstraction the API is supposed to give. The idea of using JavaMail is the fact that someday these proprietary
systems will be replaced with standard smtp / imap protocols.

I need to upgrade my 10.5.1 os on my G4/1.25 (I'm having some audio-midi setup problems), but it's a machine that is not connected to the internet. Do I have any options? Thanks!

Friends,
I'm having some audio-midi setup problems on my G4/1.25/10.5.1 machine. I'm thinking that a routine OS upgrade might help. However, this machine is not connected to the internet. Are there any alternate methods for upgrading system software? Thanks in advance!

OK, what you should do is download the updates on another machine and burn them to a disc. Start at this link http://support.apple.com/downloads/#leopard for downloads and find, among other things, the 10.5.8 combo updater that works on PPC machines, plus security, QuickTime and other updates. Going from 10.5.1 to 10.5.8, there will probably be a bunch of things that you should install. Being off the internet with the machine, you can't have Software Update sort it out, so something might get missed, unfortunately.
My suggestion is this: if it looks like you might need a download, get it onto that disc.

That means that one or more of these apps was obtained using that ID. All apps are forever tied to the ID used to originally obtain them & they cannot be transferred to another ID. Your only option is to delete this content, then re-purchase using your ID.

Ok.Heres what happens.
When I send emails to the same account using gmail webbase application , those mails (which the sender is "me") are read from my Java-POP3 code.
But when I send mail using my Java-SMTP code , and try to retrieve them using same Java-POP3 program,those mails are not read.
Here is my temp account that I am using
user : [email protected]
password: umanga123
You can see there are 3 mails (please dont delete them) , which were sent using my Java-SMTP code.And one mail which is,sent from my yahoo account.
Below Is the java-POP3 code that I am reading my messages.You can run them your self and see that the messages with "me" and not reading,only the message from yahoo is reading.
You can test following code without any modifications..
Please help,

SSL reading problem in server-side

Hi guys,
I have a problem in my server implemetation with SSL Server Socket. I have created a server socket with a specfic port and bind address. Whenever a client connecfed, i grap its inputstream and starts to read as bytes. There is no problem to open server socket and certifacate authorization, and also a client successfully connects to server. But when client writes some data to its connected socket, server cannot read anything. Server throws no exception and there is no problem in writing. But the available bytes in inputstream is always 0. When i replace SSL socket with normal socket, everything is ok, server can read everything. I confused very much. since i have no concrete exception and stack trace, I know it is hard to explain and get help about my problem. I have added some parts from my code.
Could you make any suggestions?
Listening and connection part
ServerSocketFactory socketFactory = SSLServerSocketFactory.getDefault();
socket = socketFactory.createServerSocket(port,backLog,bindAddress);
Socket clientSocket = socket.accept();
in = new BufferedInputStream(clientSocket .getInputStream());Reading part
          while (continueRunning){
               try {
                    Thread.sleep(1);
                    if(in.available()<1){
                         System.err.println(in.available());
                         continue;
                    MessageDecoder decoder= new MessageDecoder();
                    Message msg = decoder.decode(in);
                    if(msg == null){
                                       System.out.println("Decoded message is null");
                         continue;
                    handler.messageReceived(msg);
               } catch (IOException e) {
                                e.printStackTrace();
                    continueRunning=false;
                    try {
                         clientSocket.close();
                    } catch (IOException e1) {
                         e1.printStackTrace();
               } catch (InterruptedException e) {
                    continueRunning=false;
                    e.printStackTrace();
                    try {
                         clientSocket.close();
                    } catch (IOException e1) {
                         // TODO Auto-generated catch block
                         e1.printStackTrace();
          }

I process bytes whenever they are available in the
stream, thus i use available() for checking wheter
there is any bytes to decode.You are looping and sleeping and calling available(). What's the point? As you have nothing else to do in the loop except sleep according to the above code, the whole sleep/available business is still a waste of time. Why not just read()? You are also burning a lot of CPU cycles for nothing.
The problem is there is no data in the stream althogh client seems write some data. The problem is that regardless of whether there is data in the stream or not, SSLSocket.getInputStream().available() always returns zero. It always does this, and so you cannot use it for the purpose you intend.
This is no loss, as the purpose you intend adds no value to just doing a read(). Try it and see.
I discover the debugging utilities of JSSE and make
some debugs. I find that client is blocked on its
socket when it tries to write stream. I am not using
nio, so my sockets are blocking but i cannot find any
reasonable explanation for this SSL write blocking on
socket.The 'reasonable explanation' is that the peer is never reading, so its socket receive buffer is full, so the writer's send buffer eventually fills too, at which point the writer is blocked.
When i change my implementation and used
non-SSL socket, everything is ok and there is no
blocking.That's because Socket.getInputStream().available() returns positive numbers whereas SSLSocket.getInputStream.available() always returns zero.
Is there anyone who knows something about some kind
of SSL blocking?There is.

Example-CD : "Tracy Chapman , Telling stories" is not able to import . I have more such negative cases. But in other cases it works fine and the sound is great.
The firmware at the inbuild CD/DVD DS-6E2SH is the latest version.
What can I do??

hi b noir,
I don't no about virtuel drives like you mententioned. In the mean time I have rebooted the XPS and run again the iTunes diagnostics. I think the back - chance in the registry was not ready to use. Now there are another results. They are the same in case of a running CD or a not running CD. The difference in total is like before. It takes more time that iTunes reads the (bad) CD and at the there is no good sound. In both cases ( running or not running CD) iTunes diagnostics gives as a result :

I purchased Photoshop CS5 for my windows vista operating system. I purchased a canon 7 D some yrs ago no problem. I purchased canon 7D mk 11 in December 2014. The supplied software will not work with vista. Photoshop CS5 will not accept canon7D mk11. Can someone please tell me how i process canon 7D mk11 photos ?????. (is it possible to bypass camera raw and open the photo straight into CS5 without using camera raw first. if so how do i do that. if not how do i process pictures).
Thank you.
Brian in the UK.

Photoshop by itself cannot process raw image data. That is why the Camera Raw plug-in was developed. You could try the DNG converter and convert your images to the DNG format and then the Camera Raw that you have would be able to open them. I can't recommend Lightroom because you are using Vista, and Lightroom 5 cannot be used with that operating system. It may be time for you to get a new computer and upgrade your software.

Telnet read problem -- Telnet read back

I am trying to use telnet to send TL1 command to my UUT and expect to read back measurement data. I was able to read proper data once in a while but most of the time I read back the TL1 command that I sent. I tried different read mode and timeout period but nothing seem to matter. My vi was written in Labview 8.2.1 with Internet toolkit. I read in the forum about some limitation of the telnet read problem of the vi from the internet toolkit, Is there any better read driver around?
Thanks,
Patrick

Hey! I have a few questions for you that should help us solve this problem. First, have you tried out the telnet shipping example "Telnet Line Client.vi". This will help us minimize programming errors, etc. Also, what type of device are you trying to communicate with? Are there other forms of communication available? For example, does the device also have a serial port, GPIB Port, etc.? Also, is it possible to write to the device using TCP/IP (This is what telnet is based on)? Let me know the answers to these questions and I will be better equipped to help you out!!
Thanks!

MacBook shuts down abruptly after some time, then has problems starting

I have 13" MacBook that I'm having some problems with. I have OS X and Windows XP in a dual boot configuration, and the problem happens in either OS. I can only use the computer for anything from 3 to 30 minutes before it suddenly shuts down.
When this first happens, I get trouble restarting it. It often just comes as far as intialising the DVD-ROM (you hear the sound), then it shuts off again. It can take up to ten starts before it powers up again. And then it's just a matter of time before the whole thing starts again. This happens regardless if I have the charger connected or not, or if I use just the charger and remove the battery.
At first it was thought that the battery was faulty, and I received a new one last spring. However, the problem quickly returned, and I haven't bother to do anything more about it before now. Suffice to say, I miss using my shiny MacBook, and I hope that someone can point me out in the right direction. As the computer is 2 years this may, I doubt I can get it repaired for free on the warranty(?).
Long post, but I hope I've explained the problem thourough enough. I believe I did the SMC reset and software update last summer, though I'm not sure which revision I'm on. If there's any more information I can provide, please let me know. It just takes some time to get the computer to stay on long enough to check stuff

Thank you so much for answering! I've actually read your answer to other similar forum, and have just installed iStatPro. it says that my fan is "exhaust" and at 0rpm. do i HAVE to replace the fan to a new one? can I just open up my mac and clean out the fan? if so, would you recommend this instead of buying a new fan? one last thing, if I buy a new fan, is it easy for me to replace it by myself? again, thank you so much for your answer.

I have been using xfinity for some time with no problem. Now when I open it, it shuts down. I have reset, restarted, and done a sync. I also deleted and reloaded to no avail

I have been using the xfinity ap for some time with no problem. Now every time I open the ap it shuts down. I have updated software, reset, done a sync, rebooted to no avail any ideas

My Xfinity App does the same thing. Hope they are coming out with a app update.
