Sending a url to the server

hi.. can somehody help me on this..
im currently using the oscache facility to cache my pages.but the caching only happens when the page was first displayed.the loading time for the page is pretty long.
now, im tasked to create a batch job that would send all the url's to be cached into the server.so that when a user views the page it will only be cached pages.
has anyone done this kind of program??

I send a cookie to the server, but it doesn't come back.

Hey all:
I'm attemping send a cookie via an application to the servlet, and then pull that cookie back out from the servlet's response. I want to do this whole process repeatedly while retaining the same cookie.
Pulling the cookie out on the first request to the servlet works fine because I do not send a cookie to the servlet, and the servlet instantiates a new session. Next, the cookie is sent back to the servlet successfully because it is printed out on the server-side exactly as it appeared on the client side. However, after the servlet responds to that second request and on subsequent requests, I can not pull the cookie out again. On the method call, connection.getHeaderField("Set-Cookie"), the result is null. I've even inspected the connection object, and it seems empty of any cookies whatsoever. Why doesn't the cookie come back on requests after the initial request? Is there anything I can do to make it come back?
Thanks a ton in advance. Have great day!!!

you must check that cookie's path set by Tomcat is the one expected by your browser. Otherwise the former won't send it back to the server. I had the same problem because Tomcat sets the cookie path to "/webAppName" and the browser expected it to be "/".

AOL email cannot send PASSWORD securely to the server???

Hi, When I set up any aol account in mail, and click create, it always comes up with cannot send password securely to the server. This problem happened right after updating to snow leopard. Any one else have the same problem? Any solutions? Thanks.

For years and years most email servers accepted connections that were insecure, meaning that passwords were transmitted in plain text, and the email messages came back as plain text as well.
Now many servers encourage the use of SSL connections, which encrypts the data in both directions. Mail is trying to warn you that the SSL connection cannot be established, and therefore your data could be intercepted in transmission.
AOL's website (http://about.aol.com/faq/openmailaccess) states that they do not support SSL connections, therefore your only method of accessing your email is to use an unsecure connection.
Alternatively you could go to AOL.com (not use Mail.app) and read your email here as this will establish a secure HTTPS connection.
The best solution though is to stop using AOL and get either a MobileMe or a gmail account.

"cannot send email message using the server icloud" on 10.6.8

I use mail from my desktop, not from iCloud on the Internet. I have a MacBook Pro with 10.6.8 Snow Leopard. My mail was working fine until yesterday.
It says "Cannot send message using the server iCloud. connections to the server smtp.me.com on the default ports timed out. Select a different outgoing mail server from the list below.
The list has:
ICloud offline
and Icloud
Neither of them work.
What has Apple changed regarding this in September?
(I know others have posted similar message, but they were on 10.7)

Same problem here.
Recently an @icloud.com version (alias) of my existing @me.com email address appeared on my account. I can still send messages form the OSX build in Mail client as long as I am using the @me.com version of my email, but I do get this message when I try to use the new @icloud.com account.
My account with iCloud states that both @me.com and @icloud.com versions of my email are active.
Would be nice to know if this is a temporary problem of if this is a permanent one.
The settings on the outgoing mail server are default as retrieved from apple when I configured the @me.com email for the first time. I went through the troubleshooting suggestions as provided on Apple website, double checking all the settings, no joy. At the very list I can still use the old @me.com alias with no problem (for now)
MacBook Pro / Mountain Lion 10.8.2

Having problems in sending email..always saved in outbox and cannot send mail bcoz of the server failed

Having problems in sending email..always saved in outbox and cannot send bcoz of server failed

The email server you are using to send mail through requires the password, if any is required it needs to be set in the location that I pointed out in the earlier post.
It is usually the same password you use for receiving emails.
I don't use either Facebook or Twitter so I am not sure how to help with those.

Mail can not send was rejected by the server because it does not allow relaying i can not send mail i get this error every time

everytime i try to send email i get an error message saying was rejected by the server because it does not allow relaying. how can i correct this and get my mail to send from my iPhone 4s

Hello fightnfire,
Thanks for using Apple Support Communities.
I'd like you to please follow the "basic troubleshooting" steps in the article linked to below:
iOS: Troubleshooting Mail
http://support.apple.com/kb/TS3899
Take care,

Sender address rejected by the server

Stupidly, I tried to send an email to everyone in the address book without splitting them up into smaller groups. I think I have been flagged as a spammer. This is the error message I get:
This message could not be delivered and will remain in your Outbox until it can be delivered.
The sender address [email protected] was rejected by the server.
I am unable to send any emails from Mail. How do I resolve this???

It looks like you've exceeded the .Mac sending limitations, as described in the following article:
.Mac: Email Account Specifications
The problem should fix itself by just letting enough time to pass so that you're within the limits again.

Cant send email. rejected by the server

unable to send email. i can receive and view but get the error message " rejected by the server because it does not allow relaying"

No, All data and contents will not be lost.
All settings will be reset to default, so these are a few you may need to reset if you have changed them:
Enable Location Services
WIFI - to connect again
Bluetooth - Re-Pair again
Sound(Ringtone)
Wall Paper
Passcode Lock (Setting, General)
Brightness
Battery Percentage (Setting, General, Usage)
Mail (Default Account, Show Recent Messages, Fetch New Data, Time Zone Support)
Auto-Lock (Setting, General)
Messages (Notification, Messages, Show Preview) (Messages, Character Count)
Contact (Sort Order, Display Order)
Application Store Itune Account (Use existing account)
Restriction (if you want it On)
Call Forwarding, Call Waiting...... if any
World Clock (Application)

TS2621 sending message content to the server failed - on my iPhone and iPad?

How do I fix this. Thank you very much

Does the mail account work on other devices?
Have deleted the account from the devices and recreated it?

Object can't be send over to the server.

Hi to everyone,
I'm doing a connection between client and server. The client will send image from the platform to the server. The server will then create an folder in the server-side to store the images.
Thank you for reading. Hope to hear from you soon. Anytime you need clarifation, you could ask. I'll be more willingly to feel you in in more details.

/* =============================== getImage() =================================
* getImage() assumes that a connection already exists to the server.
* First, getImage transmits the image we want to get.
* Then, we wait to read the 3 objects sent by the server's ObjectOutputStream:
-- an Integer object, representing the width of the image
-- an Imteger object, representing the height of the image
-- an Image object
* The first two are Integer objects, NOT primitive int types. This
* is because the ObjectOutputStream can only transmit objects, not primitive
* types (to transmit primitive types, use a DataOutputStream).
* 1: Read the three objects sent by the server. Note each object must be cast to
its appropriate type, since readObject() returns an Object. To get the value
of an Integer object, we use its intValue() method, which returns the primitve
int value of the Integer.
* 2: The buffer object is an array of integers, which represents the image
data. In other words, buffer is an array of integers in memory which is
the source of the raw image data. Java has a special MemoryImageSource
class which is used to construct Images from raw data in memory. So, in
step 3, we create a MemoryImageSource object using the width, height, and
buffer objects.
* 3: We want to create an Image object using the MemoryImageSource object we
created in step 3. To do this, we use the createImage() method of the
Component class. Since this client class extends Frame, and Frame is a
subclass of Component, we can call createImage() directly.
* 4: Once the Image is created, it will be passed into the folder for storage
private void getImage()
Component c=null;
try{
objectOut.writeObject(img);
objectOut.flush();
int w = ((Integer)inObject.readObject()).intValue();
int h = ((Integer)inObject.readObject()).intValue();//1
int [] buffer = (int[])inObject.readObject(); //2
Image img = c.createImage(new MemoryImageSource(w, h, buffer, 0, w)); //3
//create an new folder to store those sent images
File f = new File ("C:\\Sweet_Memory");
//you can also check whether such folder exists or not.
if (!f.exists ()){
f.mkdir ();
//how to store image into the file????
}catch(Exception e){
System.out.println("Server-side: "+ img);
System.err.println("Receiving failed: "+ e);

The codes below have error message showing "IO error in initSocket() " which is in the initSocket method and "Sending failed" which is in sendObject method. HOwever i can't figure out why this error message is shown. Can anyone kindly help me out? Did i declare the wrong thing?
Please clarify with me if i'm not clear, thank a lot. Any help will be appreaciated.

Detecting the server url dynamically

I am finding it difficult to get url of the server dynamically
I am getting it through java script using window.location.host
is it possible using java

Hi,
The solution depends on the specific WL version you are using, but chances are you should be looking at the constructor of the implementation of the service provider for your specific WS. There is usually a default constructor, and a constructor that takes an URI, this second one is the one you should use to set the URI to something different than the default URI.

LG
