Java cookies problem

I have been writing a proxy server.
when client(web browser) send the request to the proxy server, the proxy server will parse the request, and access to the web server.
rmRequest is a class to parse the request.
URL u=new URL(rmRequest.url); // rmRequest is a class to parse the request.
HttpURLConnection conn = (HttpURLConnection) u.openConnection();
if there is cookies,
conn.setRequestProperty("Cookie",rmRequest.cookie);
will be added.
When the respond come back to proxy server, the proxy server will divert it to the web browser with InputStream.
The problem comes when I am trying to login to some web site.
I could POST the request with the content and getting back to the logged in page.
but the cookie is not saved to the web browser.
Which means when i click on any button later on, the GET request does not contain any cookie.
for example, i login to a forum.
after typing username and password, and click on the 'login'.
The web browser send a POST request to the proxy server and so does the proxy server to the webserver.
The webserver return the page with 'login successfully, welcome back!'.
but when i click on other link of the website, it return the login page and saying that i have not log in yet.
The web browser is not saving the cookie after logging in to the forum!
I wonder how could I get the cookie and ask the web browser to set the cookie for the logged in website.

If you are going to use "second" method then you should take care about all HTTP staff. Cookies' basics are easy - just look for "Set-Cookie" strings within server answer and remember specified cookies for future use.

Can't load Netflix - Firefox says something about cookie problem and recommends try again button. ("The page isn't redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies.)" Hit the try again button repeated ly - nothing???

I decided to give Netflix a call about this problem.
On a recording while waiting for a support rep, it said if you're having problems logging in to go to:
http://www.netflix.com/clearcookies
It works for me. Now I have to logon everytime I go to their site though versus it had kept me already logged in before this problem.
I will be using that link to get to their site until they get it fixed.

Java Session problem while sending mail(using javamail) using Pl/SQL

Hello ...
i am using Java stored procedure to send mail. but i'm getting java session problem. means only once i can execute that procedure
pls any help.

props.put("smtp.gmail.com",host);I doubt javamail recognizes the 'smtp.gmail.com' property. I think it expects 'mail.host'. Of course since it cannot find a specified howt it assumes by default localhost

Java Programming Problem

Hi all,
I was looking for this java programming problem which had to do with a large building and there was some gallons of water involved in it too somehow and we had to figure out the height of the buiding using java. This problem is also in one of the java books and I really need to find out all details about this problem and the solution. NEED HELP!!
Thanks
mac

Yes, it will. The water will drain from the bottom of
the tank until the pressure from the water inside the
tank equals the pressure from the pipe. In other
words, without a pump, the water will drain out until
there is the same amount of water in the tank as in
the pipe The water pressure depends on the depth of the water, not the volume. So once the depth of the water inside the pipe reaches the same depth as the water inside the tank it will stop flowing. This will never be above the height of the tank.
I found this applet which demonstrates our problem. If you run it you can drag the guy up to the top, when water in his hose reaches the level of the water in the tank it will stop flowing out.

Java Uninstall Problem

Java Uninstall Problem
This all came about because of a failed uninstall, using Your Uninstaller.
The {Java runtime which is all I want) is not listed now & I tried all the other fix bad uninstall type features, all to no avail.} )
When I DL & run the latest package (jxpiinstall-6u11-fcs-bin-b90-windows-i586-25_nov_2008.exe}
& run it I get:
1st message:
     "This software has already been installed on your computer.
     Would you like to install it?"
If I say no, it exits.
If I say yes, I get this second message:
     :This action is only valid for products that are currently installed."
So Now I have no Java & have no idea what to do.
Any help would be greatly appreciated.
Thanks, Neuromancer23

Sorry...after posting it i realized there was a more appropriate forum, of which it took quiet awhile to find.)
Now that I know where to find the forum list I will never double-post again.
I'll close the question if I can

Cookie problem in APEX 4.1.1

After upgrading from APEX 4.1 to 4.1.1 the first time a user visits a particular application they see a line at the top of the page of the form:
"Set-Cookie: PUBLIC_WWV_CUSTOM-F_1047528391177278_666=1316663583787701; HttpOnly "
As soon as they refresh the page, the text disappears. I believe this is related to the issue of larger cookie sizes in 4.1.1 that a lot of people seem to be experiencing with NTLM authenthication. However, this is occuring at the login page prior to authentication. There is an application process with a processing point of "On New Instance (new session)" with the following code to create a cookie:
owa_util.mime_header('text/html', FALSE);
owa_cookie.send(
name => 'PPP_SESSSION',
value => to_char(v('APP_SESSION')),
domain => '.dooda.com',
path => '/');
owa_util.http_header_close;
As soon as I remove that process, the issue goes away. Of course that raises more troublesome issues. :)
The workaround for the NTLM/cookie problem doesn't seem applicable here. Does anyone have any suggestions?
Am I leaving out any helpful information? (I'm not so familiar with APEX and I don't know jack about web development).
Thanks for any help.
Chris

Chris,
This is a little bit of a guess here, but can you try removing the line:
owa_util.http_header_close;
from your On New Instance process?
What appears to be happening is APEX is attempting to write the session cookie, but the HTTP headers have already been closed.

Cookie problem with this forum?

Today I am no longer able to connect with this forum with my Safari browser. All I receive in a page with the 6 categories and nothing else. Also, I am not able to log in. However, I can log in using Foxfire with all the topics correctly displayed. I suspect it must be a cookie problem and if that is so, I'm not sure where to go in Safari to delete cookies.

Same problem is back after only one day. When using Safari (latest version), if I click on the following link...
http://discussions.apple.com/category.jspa?categoryID=218
All I see is the Category headings (no latest posts) and I'm NOT automatically signed in. When I attempt to sign in, I then go the the "new user" data page. After signing in, I get very restrictive access to the forum.
When I sign in with Firefox, everything is normal. Yesterday when I had this problem, I erases the cookies from Safari and everything returned to normal. I hate to have to erase my cookies everyday to get access here as I prefer to use Safari.
Is this happening to anyone else?

OS X Lion - JAVA SCRIPT PROBLEM

Would you please write some more details? explain the problem and what web site backend you use. Thanks.

Cookie problem using safari

Hi all!
I seem to have a cookie problem on Safari on my iPhone. This makes that it's very difficult for me to Ise forums, Google Reader, etc. I tried all three settings but apparently Safari doesn't store my cookies.
Anybody else have this problem? I'm using firmware 1.1.4.
Thanks,
Ton.

The first step you should take is a reset of the phone to potentially clear up the problem. To do this, hold the home button and the top button simultaneously until you see the apple logo. If this doesn't cure the problem, a restore is in order, and this can be accomplished from iTunes. First try a restore from backup. If this doesn't work, you can do a restore to factory from iTunes, which should clear up the problem if the prior steps haven't worked.

"Java enabled" - "accept cookies" PROBLEMS

Just today I ran accross 2 big problems:
1. A discuission group I regularly post to won't allow me too as it says "Java must be enabled to post" - it IS enabled in my prefs?!?
2. A secure commerce I've logged into before told me "must be set to accept cookies" - again, it IS in my prefs.
All I've done to try and fix, is restart.
My version is: OS X 10.2.8, Safari 1.0.3

I am having the same probem with the "must be set to accept cookies". I get the message when I try to log onto a secure banking site. Firefox works fine. Anything I can do to remedy? I emptied cache, deleted cookies from site, and emptied the icons folder.
One more thing I should add. When I registered for the site originally, I was able to log on and view my account, but only that one time. Now i get the cookies mssg when I enter my log and pass and hit "log in".
Running Tiger and Safari 2.0.1 with all updates installed.
Thanks

Problems enabling Java/cookies to work on firefox macbook pro

I am running Firefox. I've checked that Java is enabled and I have the latest update. Yet it is only this one site that it keeps giving me the same message " enable java and cookes" to view site. Is this the issue where firefox does this on sites it deems unsafe? and if so how do I sort it out. Up until 2 days ago I was able to access this site without any issues like this. This is on my macbook pro. I went into system setting and found Java upload so it's there. when I go into preferences on firefox though there is nothing at all about enabling cookies or java?? Should I revert back to Safari to stop this issue?
Cheers

As I said in your other post this is the iPod touch forum. Post in the MacBook Pro or OSX forum

IE 6.0 Cookies Problem

I am trying to use iSQL*Plus with Microsoft Internet Explorer 6.0. I can sign on just fine, but every time I try to run a query, I get the following error:
SP2-0915 Cookies may have been disabled
iSQL*Plus works fine with my old Netscape 4.72, but I would really like to make it work with IE 6.0.
I have gone to the Tools, Internet Options, Privacy and set it to "Accept All Cookies". No luck.
Does anyone have any Ideas?

Thanks for trying, but still no luck. I have 5 PCs on my network at home. Two are XP machines and 3 run Win 98. iSQL*plus works using Netscape and fails using IE 6.0 on all 5 machines.
I sign on to the HR database, and I get into the iSQL*Plus screen just fine. I then type:
SELECT * FROM employees;
I click on execute and I get the following:
SP2-0915: Cookies may have been disabled
I then went to the Tools - Internet Options - Security tab and set security to "Low" for the Internet Zone, Local Intranet Zone and Trusted Sites. On Trusted Sites, I clicked the Sites button and added the URL for iSQL*Plus to the list of trusted sites.
I closed IE and reopened it. I checked to verify that all my changes had "taken". I logged into HR. No luck. Same problem.
I logged into Scott/Tiger. I tried "Select * FROM EMP". No luck. Same problem.
I disabled my antivirus software (McAffe). No luck. Same problem.
Is there possibly some Java setting that I have messed up?

HttpURLConnection & cookie problem

Hi,
Well I did have the solution to my problem a few days ago, but it seems that I somehow didn't save the changes to my code.
I'm wanting to log into a website and download some customer information. Upon logging in, the login page sends cookies. Basically, I collect the cookies and go to the main page which requires another username and password which the login pages sends. The new username/password & cookies then needs to be sent to another page to login. Hopefully, you understand; otherwise, I'll attempt to expalain again.

This may be difficult to read due to all the debug info I have coded.

P.S. I do apologize if this has been posted in the incorrect forum
Like I said, I did have this working a couple of days ago, yet it fails now.

Not sure why you would use a substring to send the cookie. I have this code sample to
make a request to an asp page and send contiues request to that asp page within the
session set the first time (session is done with cookies in asp).
here is the asp page:
<%
if Session("mySession")="" then
     session("mySession")=1
else
     session("mySession")=session("mySession")+1
end if
response.write(session("mySession") & vbcrlf)
