SecurityExceptionEx[Host], how to get over it ??

I have written a Java applet, which is supposed to work as a client for a server
which is already running and well (and is'nt at the same computer as the client).
The applet should connect to the server (Socket) via Internet and then move the information back and forth between itself and the server.
The applet doesn't work, although the code does (when executed as a stand-alone application), and it is propably due to the Java security restrictions for applets. It complains about SecurityExceptionEx[Host] ...etc.
I would be VERY greatful, if someone struggled with the same problem and solved it could kindly tell me what kind of procedures I have to make in order to get the applet running aswell. I have tried to find information from the Net and I've come to the conclusion that it's not a piece of cake to overcome this problem. I'm totally unfamiliar with the " ini-files, cab-files, signing applets etc." and messing around with them so some kind of lesson starting at the very basics would be just great.
Thank You already in advance !

Probably, what you are doing in your applet is not allowed unless you have a certificate granting you permission.
Here is a link to a page that describes how to create a self-signed certificate.

Hope this helps!

    Go to the  menu/About This Mac - what OS version shows there?
    Do a backup, preferably 2 separate ones on 2 separate drives.
    Revert to a Previous OS X
    Revert to Snow Leopard
    If you do revert, I'd use Setup Assistant to restore your data. This process takes a while, so do it when you won't need the computer for several hours, based on my experience.

  • How to get over DYNPRO_SEND_IN_BACKGROUND?

    Hi,
    I have the following problem:
    I connect via ECC5 to R/3 4.6C.
    I need to enter data into an R/3 transaction.
    I wrote a BAPI that does a batch input (yes, it is a sin).
    The problem is that I get the error (actually dump from the R/3) - DYNPRO_SEND_IN_BACKGROUND.
    This is because I try to do a batch input on foreground while the system does it in the background.
    Does anyone have a nice idea how to get over this?
    Thanks,
    Itay

    Hi,
    I am not sure about this, but if you launch the Batch input using standard program RSBDCSUB, should it not be launched as a background process ?
    best regards,
    Guillaume

  • After having no internet for over 24hrs, my IPad has completely shut down. I have tried everything I can think of, including a reset but think that was a really bad move!! Any ideas for how to get my pad back? Simple words please..I am not a pro AT ALL.

      My internet was down for over 24hrs after a storm. During that time, my IPad completely shut down and I can't get it going again.  I studied the manual but couldn't find a similar topic.  I reset it and now it is totally goofed up.
       Does anyone have any ideas or should I just take it to an Apple store and pay??  Any solutions you may have, PLEASE use simple words as I am not a pro, by any means....probably why I'm in this situation.
       Thank you in advance.

    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

  • How to get information about creation of a virtual machine on a Hyper-v host.

    Hi,
    How to get information about creation of a virtual machine on a Hyper-v host?
    I need: host name, time created, creator user.
    I saw in Hyper-V-VMMS but I found info about movements of VM between hosts.
    Thank's in advance.
    Denius Valiant

    For Host Name * Created Time Use This Command In PowerShell 
    Get-VM -Name (Read-Host "Type Your Vm Name") |select CreationTime , ComputerName
    and for Create User , As i know you should see on Event Log . 
    Go To Event Log Viewer--->Applications And Services Logs--->Microsoft--->Windows--->Hyper-V-VMMS--->Operational 
    You can see in Event Log who create the Vm.

  • How to get notified when changes happen on Hyper-V host or VMs

    Is there a way to get notified on Hyper-V host or VM changes? Our intention is to notify the system-administrators on any changes.
    1. How to get notified when new VM is created (or deleted) on Hyper-V.
    2. How to get notified when any memory/CPU/disk is added (or deleted) on any VM(s).
    In general: 
    - Get notified when any changes happens to Hyper-V host.
    - Get notified when any changes happens on any VMs.
    Our target servers are Windows Server(2008, 2008 R2, 2012, and 2012 R2)
    We tried to get the notification using "Event Viewer" on different Windows servers (2008, 2008 R2, 2012, and 2012 R2)
    We were able to get event-logs only on one of our 2012 R2 server as described below on creation/deletion of VMs (on another 2012 R2 server, we did not got any such event, Is there any setting required on host computer to get Hyper-V event-logs in "Event
    Viewer"?)

    Thanks for your reply,
    Just to make it more clear:
    In our environment we have enabled Hyper-V on following Windows servers: 2012 R2, 2012, 2008 R2, 2008. The environment is very dynamic, VMs are getting created and deleted very frequently. Our intention is to get notified by any means on VM creation/deletion,
    currently we are relying on event-logs (we are OK with any different mechanism for such notification if there exists, i,e other than event-logs)
    We were able to get event-logs only on few of our 2012 R2 server on creation/deletion of VMs. On another 2012 R2 server, we did not got any such event (do we need to make some settings on 2012 R2 to get events? If yes, what are those settings).
    Also we are not getting any such event of VM creation/deletion on our Windows Server 2012, 2008, 2008 R2. Is there any setting required on hese host computer to get Hyper-V event-logs in "Event Viewer" for VM creation/deletion?

  • How to get low performances alert for Hyper-v Host ON scom

    Hello Expert,
    We have to implement a scenario VM Live migration which involved (SCOM,SCVMM,SCORCH Parts).
    where SCOM parts  will monitor the performances of SCVMM 's Hyper-V hosts and VMs running the within the Hyper-v hosts.
    when the VMs utilization exceed the threshold and then scom monitor checks the performances of Running Hyper-v Hosts ,then using SCORCH automation ,VMs are moved to one of the best performances the Hyper-v hosts.
    To implement this ,I have integrated SCOM 2012 R2 AND SCVMM 2012 R2 AND enabled the PRO Tips.
    but don't know how to get alerts and configured related to performances of VMs and Hyper-v host.
    What will be next  needed to achieved this from SCOM PARTS.

  • HT4889 Replacing System hard drive with a new one. How to get everything over to the new boot drive?

    Replacing System hard drive with a new one. How to get everything over to the new boot drive? Should I use Carbon Copy or does apple have a better untility to do this?
    I can't get my current system drive (OSX 10.8.3) to start on the first try. I always have to shut down and restart again to finally see the Apple logo.
    Have used disc utility to repair the disc and permissions several times and that works. The next time I boot up, it works fine and I get the apple logo, but then the second time I boot up, it's back to the blank screen again and it only boots after the second try.  I have tried this repair three different times now always with the same result. Works right the first try (after the repair) then from the second time on it doesn't work. I just get the white screen until I reboot a second time.
    Thinking I should change drives but what's the easist and best way to move everything over to the new drive so it will boot correctly with all my data on it. This is the system drive for a Pro Tools 10HD setup. MacPro 3,1 with 16 gigs ram and OSX10.8.3 on it.
    Thanks for any help!

    If you have a time machine back up of your current drive you can do this
    Shut down your computer, install the new drive. While the computer is off plug in the external hard drive that you have your time machine back up on. Hold Option key while the computer turnes on, let go of the option key once you get a grey screen. Shortly after you'll see  a list of bootable drives, select the one that has your time machine back up on it and boot into that drive.
    From there go into disk utility, format your new drive too, osx extended journaled ( I think, double check that, its been awhile since ive had to do this), hit format
    Exit disk utility and then you can use time machine to copy all your exisit data to the new hhd and then your pretty much done.
    There is also a program called Carbon Cloner that will do esentially the same thing however I've never uesed it.

  • How to get text when mousing over image?

    Hey there, I am extremely new to Flash, but know other Adobe programs so tend to learn quickly.
    I desperately need to find out how to get text to pop up when i mouse over PART of the image and i havent been able to find any help online in the last two days (pulling my hair out in stress).
    Now i uploaded a rough mock up i did on Photoshop, so you can see when i mouseover the top layer of the cake i need a line to stretch out and the text to pop up at the end of it. Similarly if i moused over the cherry another piece of text needs to come up in the same manor.
    Also since i need it to be a website link so what format do i open it with when i go to FILE- NEW?
    Honestly thank you so much in advance to anyone that helps

    First you have to choose if you want to handle devices. If not and you want to stay in Flash I'll stick on topic.
    In the HTML version you could either use a good old fashioned image map (they're still fine in the HTML5 era) or you could use a layering technique (here's a random layering example).
    In Flash you can do it a few different ways. If you intend on keeping the image intact as a single object then you'll be essentially doing the same as an image map. You can draw invisible hitareas on the various parts of the object and have those areas trigger a specific function that will display your text. If you break up the image into the separate parts then you can directly assign those parts to fire off a function themselves.
    First I'd like to know your desired direction.

  • My link preview has disappeared from the bottom left of the page (it no longer pops up when I hover over a link.) Thoughts on how to get it back? I really LIKE having it!

    My link preview has disappeared from the bottom left of the page (it no longer pops up when I hover over a link.) Thoughts on how to get it back? I really LIKE having it!

    It is possible that the screen is too high and that the scroll bar and the find bar and add-on bar fall off at the bottom.
    If that works then close Firefox (File > Exit/Quit) to save that setting.
