What does it mean same JVM?

What does it mean "located in the same JVM"?
For example, when using local interfaces for EJBs, the EJBs must be located in the SAME JVM?

When you type the following at the command line on windows....
notepad
An "application" called notepad starts.
If you type it again a second application called notepad starts.
There are two applications and nothing (for terms of this discussion) is shared between them. So if you write "abc" in the first one, then there is no way for the second one to ever see that.
When you start jboss/weblogic on server A that starts one application.
If you start jboss/weblogic on server B then that starts another application.
The 'local' EJBs run in the application where they are called from. While a remote on might run on A or might run on B, you have no idea where it really is.
And a local on A will never be visible to anything on B. Where that isn't true for remote objects.

  • 'Device sharing same IP address as your computer' - what does this mean?

    I purchased an Airport Express yesterday and was having connection problems after setting it up to only join my existing network (to play wireless audio to speakers in the kitchen) - I seem to have solved the issue by switching off WPS on my base station (provided by my ISP)
    My question is: after making this change to the settings, I got a message saying 'this device' (presumably meaning the Airport Express) was now sharing the same IP address as my MacBook Pro.
    What does this mean, and will there be any detrimental effects?

    Thanks BTF. Presumably only my MacBook Pro and the Apple TV are connected to the internet as the Airport Express is only set up to join the existing network with the crappy router as the base station. Neither the ATV or AE have static IPs assigned.
    I have since restarted my MacBook Pro and at present have Airplay audio streaming to the AE and video to the ATV simultaneously without any (at the moment) problems.

  • Multiple JVMs - What does it mean

    Hello,
    I was trying to understand this for quite a while. Googling around just obscured the use of the term.
    Could you please tell me what does it mean when I hear someone say :
    "This machine has multiple JVMs....." and ofcourse, how you can bring up just one amongst the many JVMs (by locally doing something or remotely instantiating it ) existing and running code there,
    How can I setup multiple JVMs on my desktop ?
    Thanks,

  • What does it mean when a pop up comes up and says that someone else is using the same IP address as myself?

    It only comes up a couple times, but what does it mean? Does it mean I've been hacked or something? It also says to change my IP address if it happens again but how the heck do I do that? I don't even know how to contact my network manager to find out what's going on? Is this something I really need to worry about? Please help I need to know what's going on?! Thank you!

    It means that your router doesn't assign IP addresses based on a hash of the devices MAC address but instead assigns them in sequential order.
    On Monday device A had IP address X and device B had IP address Y because they were turned on in the order A then B.
    On Tuesday device B was turned on first and it got IP address X for whatever reason.
    When devfice A was turned on it asked for IP address X but was rejected because X was already in use.
    That's when the error message was displayed.  It's complaining that the IP address it had yesterday isn't available today because it's already in use by another device.
    If the router has the ability to do DHCP reservations, configure the router to assign IP addresses based on the device's MAC address.
    Or always turn devices on in the same order.
    Or get a high end router.

  • Backup failed . Make sure your computer and backup drive are on the same network. What does this mean?

    Backup Failed.  Comment is "Make sure your computer and backup disc are on the sme network and the backup disc is turned on".  What does this mean?

    Just back from the dentist.
    Did a hard reset and when i asked time capsule to do a backup it tells
    me
    "Time Machine could not complete the backup. The backup disk image is already in use"
    I think I misunderstand how this back up device works.
    Is it to be plugged into the back of the router with an ethernet cable?
    I have the Time capsule sitting beside my Imac.
    The cable modem and router are in another room
    I am new at this stuff.  Thank you for patience and help

  • I bought the iPhone 4s and my battery used to reach 32% and then the phone would shut off. Then it reached 46% and the same thing happens, and now it shuts off at 53%. And it start recharging from the percentage it shut off at. What does this mean?

    What does this mean?

    My iphone 4s just developed a similar problem.  Ultimately, after a visit to the Genius Bar at which I was offered a replacement phone for $149, I took the phone to a non-Apple repair shop which diagnosed the problem as tarnished pins in the docking connector and replaced the connector for $49.
    The symptoms I experienced were that the phone would not pull a charge.  I tried different cables, wall outlet versus computer USB connection, etc.  The screen stayed black until I depressed the sleep button, at which time the red battery / lightening bolt symbol would flash three times and then the screen would go black. 
    If your battery is dead, that icon will not show up at all.  If you get the icon, it means your battery is run down and needs to recharge, but the defective docking connector is preventing the battery from taking the charge.

  • Why has my monitor suddenly begun to have a moiré pattern all over – it is even showing up on my icons on the dock? It appears to be very thin bright green vertical lines. I have a 2008 iMac which is running 10.6.8. What does this mean?

    Why has my monitor suddenly begun to have a moiré pattern all over – it is even showing up on my icons on the dock? It appears to be very thin bright green vertical lines. I have a 2007 iMac which is running 10.6.8. What does this mean? I've attached some screen shots below.
    Also experiencing some funky issues with my wireless keyboard. With new batteries, it will just stop functioning. Certain keys intermittently won't work. Also the fans go on as soon as I turn the computer on - some times they stay on and sometimes they don't. Ever since upgrading the operating system - I've been having many issues with this iMac. Not happy. Any answers out there?

    Thanks for your reply LexSchellings, There is no disc in the drive and I went through the suggestions you put forward on the phone with Apple support without any luck. I can put a disc in but it pops straight back out again without registering on finder.
    The idea of using an external drive was to enable me to avoid the cost and loss of productivity whilst machine in repair... if I have to take it in to get the old drive removed than I might as well have a new internal drive put in, although I do worry about the reliability of these apple drives given my experience with this one coupled with my limited online research ... on line forums seem to be full of people with the same problem (although perhaps searching such forums is bound to make it seem a common problem as users with perfectly working machines are less likely to post (?)) Your reply suggests that no external drive will work whilst the existing drive is in place.
    As a postscript: I do realise that this is a user forum ...my secondary question was asking if anyone knows how to put forward a case/complaint to Apple... I can't find a link on the support page that would enable me to do so and I was wondering if anyone on this user forum had any ideas/experience..

  • TS1424 When I click to play my songs in the library they will not play and show a circle with an exclamation point in the middle of it, what does that mean and how can I get them to play?

    When I click to pay my songs in the library they will not play and it shows a circle with an exclamation point within it. What does that mean, how do I fix it, and how will it play my songs again? They used to play before on my Iphone4 with no problem, but since I upgraded to the Iphone4s there is an issue.

    I am having the same problem. I have just tried this. Unplug iphone > open itunes > delete all music from itunes library > close itunes > re-open itunes > add music from original folder > plug in iphone > select songs > press sync > unplug iphone using eject button onscreen > checked phone .... still nothing in music folder on phone. On itunes the "On this iphone" tab the songs remain there but greyed out.

  • HT1710 What does it mean if the blue screen appears and stays on with no further activity?

    My disk failed. Apple store replaced it with a disk with OS X. I tried to load from valid time machine backup. eventually I got a blue screen.
    What does this mean and what should I do?
    Here is more of this story:
    When I picked up my computer after the disk was replaced, I was told I could do a time machine recovery. After about 6 hours the recovery said it had less than a minute to go and was transferring "your" network settings. at 9 hours it said the same thing.
    I rebooted DVD to try to reload MAC OS X but it crashed with "INSTALL FAILED  MAC OS X could not be installed on your computer Click restart and try again"
    I did but it would not boot.
    I reloaded the disk utility and and it showed no problems but the next OS X install failed (hung).
    I then wrote zeros to all the disk (could not find a reformat command). This went tith out error.
    I restarted the OSX install and it appeared to work.
    I started the install from time machine again and it hung in the same place. (less than a minute remaining. The completion bar had a sliver of white at the end but was mostly blue)

    It just means it's hungup just before completing, we can get more info with Verbose boot...
    CMD+v keys on bootup...
