How to share Singleton in different JVM?

How to share Singleton in different JVM?
Suppose we have two application installed at different server, how to share the same Singleton?

You could use the sun game server's persistence mechanism. That would work, at possibly too great an expense than technically needed to make a shared singleton.

HT1203 iTunes: How to share music between different accounts on a single computer - I tried to use the instructions to configure 2 different windows users sharing the same iTunes library. I could not get this to work per the instructions.

I tried to configure 2 windows users accounts using a single library per the instructions in HT1203. My iTunes library is on an external drive. I cannot get this to work. Any suggestions?

To give other users read-only access to your iTunes library, use the Sharing features of iTunes. Sharing works over the local network as well as on the same computer. See the built-in help for details.
If you want to give full read/write access to more than one user, see the support article linked below.

There is a way to share the library without moving it to a secondary volume. If you really need to do that, ask for instructions.

It is almost as if the program does not exist on my computer. If I search for it, the only thing that comes up is the installer. I cannot find it anywhere despite the fact I have installed it numerous times, uninstalled it and conducted a fresh install, and the Adobe website checks says that it is installed.

How to share memory between different VMs?

Hi, dear all!
I don't know if it is possible to share memory between different VMs. I know its easy for threads. Now my problem is that I want to start serveral applications which share only one copy of data, I don't know what's the right way to do that.
Thanx

They are some volume data for visualization. I want to
serveral rendering servers on a single machine, the
data size can be up to 1024*1024*1024 ( or even larger
I don't know if I HAVE TO use threads in order to
share the data, however, threads are not preemptive as
processes I think, is that true?
Not really sure what that has to do with it.
I believe the VMs for most common OSes use preemptive thread scheduling. I know windows does and I am rather certain that solaris/linux also do that.
A number of suggestions were made above for your problem. Memory mapped files allow multiple VMs if memory mapped files work for your VM/OS. Or you can use a single VM.
Given that your dataset is 1 gig or larger you might want to keep in mind the limitations of modern OSes. Windows for example will not normally allow any application to have a process space larger than 2 gigs. And on all OSes the VM heap limitations for 32-bit VMs are below 2 gigs by several hundred mega-bytes.

How to share ibooks between different accounts?

I have a friend with the ipad and she would never give me it. Is it possible to tranfer the book from the ipad to my mac without deleting her other data? because when you connect a new device it asks you to delete all files.

How to share HttpSession between different web application ?

I have two web application ( ie two different war files), I discovered that the jsp in the two war files are not able to share the HttpSession, may I know how to you share the HttpSession between two different web application ?

From the api doc:
"Session information is scoped only to the current web application (ServletContext), so information stored in one context will not be directly visible in another."
You can not share a Session object between web apps. You can create your own sessions using a database, textfile or hashmap. Do a search on the O'Rielly web site for psuedo-sessions.

How to share music between different accounts on a single computer. Using this, I can out one account into a shared public folder, but when I want to put a second one there, it says it already exists and do I want to replace it?

I followed the instructions, but when I got to move a second folder to the new shared folder, it told me it already existed and did I want to repalce it? Not prepared to do this, and lose my wife's itunes songs. I am still in trouble from losing her play lists when I went to IOS 5!

Hi, remember to set the ownership & permissions for files/folders if you want to be able to amend files or change them from both accounts. If a file is created in one account. it may only be viewed in the other account. but if you change the ownership & permissions from "read only" to "read and write" then files can be amended from both accounts. To get the info, simply click once on the folder or file then command-i to get the file/folders info. you can change things there. Permissions can only be change from the account the file/folder was created in.

iTunes: How to share music between different user accounts ...

HT3819 How do I share music between different users on the same computer?

I understand Home Sharing helps me share music across different computers. How do I share between different users on the same computer? We have a few instances of iTunes on a single computer and have to download from the same CD each time. I must be doing something wrong - seems crazy to have several copies of the same song on one hard-drive when Home Share allows for sharing across computers - how do I share within the same computer? Please outline specific steps. THANKS.

Hello Whigged-out,
It sounds like you would like to share one library between two different users on your iMac. I found an article with steps you can take to accomplish this:

How to share my iTunes Music Library

My wife and I each have our own iPod and we want to share one Music Library on our desktop computer. I follwed the instructions in iTunes:" How to share music between different accounts on a single computer". This entailed moving the iTunes Music Folder to a publicly accessible location:
c:\Shared Documents\Shared Music\iTunes Music
I can access my library, but my wife cannot. I used EDIT, Preferences, Advanced to change the location in her account to the above path, but still no luck.
The path actually displays as:
c:\Documents and Settings\All Users\Documents\My Music\iTunes Music
What to do?
Tom

We share a library by using separate playlists for each iPod.
I'll try to explain.
If your iPod is connected to your computer And iTunes is up and running , you should see it listed along the left hand side of iTunes. If you single click on its name, you can also change its name.
1) Create a playlist that you would like associated with that iPod. Give the Playlist a name that is useful to you - perhaps similar to the name you gave the iPod. eg. "Person 1's iPod" and "Person 1's Playlist."
Go to the EDIT Menu at the top of iTunes and select PREFERENCES
Click on IPOD tab.
Click on MUSIC tab
select AUTOMATICALLY UPDATE SELECTED PLAYLISTS ONLY
select the Playlist or playlists that you want on that particular iPOd (eg. ""Person 1's)
That's how We've been doing it.
If up until now , you've been doing it manually, be aware of what the difference is. (between manual and automatic update)
If you have nothing in Person 1's playlist, then the result will be nothing in Person 1's iPod.
You should be able to go back to your old way just by de -selecting those options in the same Preferences area if you don't like this system.
I hope this helps. Good luck.
