How to read or write cookies within Applets?

To make a session between an Applet and a Servlets I want to read and write cookies with an Applet.
Does anyone know if an Applet is allowed to read and write cookies? And how to make it?

All you have to do is type cookies in the search box and click search and you'll find topics such as the one posted below:

How to read and write a string into a txt.file

Hi, I am now using BEA Workshop for Weblogic Platform version10. I am using J2EE is my programming language. The problem I encounter is as the above title; how to read and write a string into a txt.file with a specific root directory? Do you have any sample codes to reference?
I hope someone can answer my question as soon as possible
Thank you very much.

Accessing the file system directly from a web app is a bad idea for several reasons. See http://weblogs.java.net/blog/simongbrown/archive/2003/10/file_access_in.html for a great discussion of the topic.
On Weblogic there seems to be two ways to access files. First, use a File T3 connector from the console. Second, use java.net.URL with the file: protocol. The T3File object has been deprecated and suggests:
Deprecated in WebLogic Server 6.1. Use java.net.URL.openConnection() instead.

How to read and write on ntfs partitions??

Hello everyone, thanks for viewing my post. I want to know how to read and write on ntfs partitions under sata hd on my arch64 system. I'm using kde as my de and dolphin does sees it but can't access it anyway. I didn't had problem so far on mounting usb drives it just automounts maybe because it is a fat partition not a ntfs? Please I need your help...Thanks in advance:)

You will most likely need to rework your fstab. The one from my desktop is shown below. If you want regular users to be able to access the partition, then you will need to change the gid option as I have done. Although you could create a group just for people you want to have access.
You will need to know the device that your windows partition is held on of course. In my case it is my first hard disk, first partition, hence /dev/sda1.
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>
none /dev/pts devpts defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/cdrom /media/cdrom auto ro,user,noauto,unhide 0 0
/dev/dvd /media/dvd auto ro,user,noauto,unhide 0 0

/dev/mapper/nvidia_fbgfhehd3 /var reiserfs defaults 0 1
/dev/mapper/nvidia_fbgfhehd5 /opt reiserfs defaults 0 1
/dev/mapper/nvidia_fbgfhehd6 swap swap defaults 0 0
/dev/mapper/nvidia_fbgfhehd7 /home reiserfs defaults 0 1
/dev/sdd1 /mnt/andromeda vfat defaults 0 0
/dev/sda1 /mnt/windows ntfs-3g defaults,user,gid=users 0 0
My XP partition is set to mount automatically, as I regularly interchange documents between the OS's.
Hope that helps.

So, I am able to convert input data into json format, but how can I able to write and read this data from a json/text file.
How can I do?
Thank you in adv and please, reply soon.

We don't have many samples left for Windows Phone 7 + Azure, the closest one to what you want to do is probably:
Using Local Storage with OData on Windows Phone To Reduce Network Bandwidth
this sample uses the local database feature: 'LINQ to SQL', available to Windows Phone 7.1 and 8.0 Silverlight applications, instead of simple file storage but even if you choose to stick with simple file storage I believe you should be able to adapt the
networking related portions of the sample to your particular application.

How to read and write Unicode text with MS Access?

Hi all, I'm new to Java, so please forgive me if my question is too ... ^_^
I'm writing a small program that read and write data with MS Access. However, when I insert Unicode text into the database, it has wrong encoding like this "h?y l? n?m".
Please tell me how to fix this.
Thanks in advance!

The following forum thread might be enlightening:
http://forum.java.sun.com/thread.jspa?threadID=573855&messageID=2870785
I myself do not use MS Access, but a PreparedStatement is in general the best option.
You can set parameters in the SQL which then get converted and even protected against SQL injection hacking.

How to read weblogic user/password within a J2EE app ?

All,
There is an J2EE that exposes a webservice and the service can not be secured with ws-security since the service is an exact implementation of an standard that does not mandate ws-secutiry and only insists on SSL/TLS. The application however needs a legitimate authenticated weblogic user for the rest of its work and hence the app has to read a known user created in the weblogic and then read its password as well and authenticate within the app and use that authenticated subject. User can create this predefined user in weblogic and we may ask user to store the same weblogic password also in a CSF like OPSS and then have the app read the CSF, but since the password is available in the weblogic internal ldap, we want to leverage that and read the user's password using any of the weblogic mbean's APIs. Can anyone provide a pointer on how to read a user's password within the Weblogic's embedded ldap ?
We referred to this Developing with the User and Role API - 11g Release 1 (11.1.1) & 6 Managing Security Realms with JMX but could not successfully get it working with J2EE app (Servlet/Filter).

You can use JMX

How to read and write(a file .txt) from a URLConnection

I try to read and write on one URLConnection. Is it possible ? How can i make it ?
The reading part of my application work's but not the writting part
That's a part of rhe code that i use to write :
String Line = "Hi";
MyUrl = new URL(this.getCodeBase(), FichierEvenement) ;
Con = MyUrl.openConnection() ;
Con.setDoOutput(true);
Con.setDoInput(true);
Con.setUseCaches(false);
Dos = new DataOutputStream(new BufferedOutputStream(Con.getOutputStream( )));
Dos.writeUTF(Line);
Please help me :)

What are you doing with the bytes written to the OutputStream? This info would help, but i do have a suggestion. I ran into this problem when trying to write strings using writeUTF. The output was all screwed up. So, maybe change your string to a character array. That way Unicode is displayed properly. This in conjunction with writing to an .html file instead of to the connection itself might work.

Mac Mini Sever - Public Share - how enable read and write permissions for new remote files

Hi,
this Sunday a friend ask me to help hum with a problem on is Man Mini Server. He has a small office and uses the mini server to share a public folder to all his employees.
Everyone that creates a file, saves it to the public folder at the mini mac.
That problem is that, who creates the file owns it and remains with read-only permissions to everyone else. The owner has to change the file permission in order to the rest of the employees can work on it.
I do not know mac arquitecture, I only work with windows and linux, but i suspect the principles are the same.
We try to create another folder , and share it, but it happens the same. Have you any ideas on what is wrong?
I suspect it has anything to do with de file Sharing at the mini mac, but it has read and write permissions for everyone.
Thanks for your help.

signed applet. You aren't going to find any easy way to distribute that policy file to users, and that policy file, if you asked me to put it on my PC, I'd tell you to take a flying leap. That would open any applet to access.

How to read and write c

I am trying to store some information received when I login to a web service. However im having a hard time understanding how cookies are handled under CEP. Documentation says that cookies are stored at:
/Users/<user>/Library/Logs/CSXS/cep_cookies
but the file is not there.
Im also using the CEP HTML Test extension to test the cookies. I see the sample works properly, meaning that it loads the cookie the next time the page is requested, however I don't see the cookie file in my file system. Can someone please shine light on where the cookie file is located?
I can see under the cep_cache directory that there is a Cookies file under the folder of my extension, which seems to be a Sqlite file. I have tried to use the example provided in CEP HTML Test extension but I just cant seem to read back the cookie I set.
Here is the code
function setCookie(cname,cvalue,exdays) {
    var d = new Date();
    d.setTime(d.getTime() + (exdays*24*60*60*1000));
    var expires = "expires=" + d.toGMTString();
    document.cookie += cname+"="+cvalue+"; "+expires;
function getCookie(cname) {
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for(var i=0; i<ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1);
        if (c.indexOf(name) != -1) {
            return c.substring(name.length, c.length);
    return "";
setCookie('FOO','BAR',7);
console.log(getCookie('FOO'));
Im running this on a local server using an unsigned extension (still in development). Please help. this is driving me mad!

I also must mention that I did a test with the code in a chrome browser. When I use a webserver (apache) the cookies work, however when I use the file access file:/// the cookies fail. This leads me to believe that there is header information that is not available when using file access.
When I run the extension under After Effects I see that the alert title reads file:///... as the location. Does this change when the extension is signed? would that start including the necessary header information to make the cookies work?

Full memory control: how to read and write memory on any address?

I am programming in Visual Basic Express a long time, and now i want something more. I need to read and write bytes in memory on any possible address, and also to get a handle or first byte's addres of any declared object(Integer, String, Bitmap, ...) and
to declare an object to some memory addres. Does anybody know some API function (function that copies blocks of memory from one to another place and gives an address of an object) or any other way to do this, and if knows please write an example code that
CAN be used and it's VALID in Visual Basic 2010 Express or Visual Studio 2013 Express or similar .net basic tools.
Thanks

Hello Donaastor,
the OS might prevent you from writing/reading to "any possible address" because you could read others memory which is not allowed. You will get a security Exception :)
But of course you can read/write every part of "your" memory. Than you should use Joel's answer.

HELP!: How to read and write to External hard drives? What file system to use?

hey all, this has been really frustrating for me today. i want to be able to write to an external HDD that's formatted in NTFS. today i find out it isn't possible to write to this file system on a Mac and that on FAT32 it is possible. however, FAT32 can't address files larger than 4GB so this hurts me a lot. are there any other file systems that'll allow me to read and write from a Mac? my goal was to use freeNAS to build a NAS with an old tower and connect my external hard drives to it, but if i can't write to them this may not be possible.
thanks guys, i'd appreciate any help!
