Change default VM from "client" to "server"

Hi,
By default, java uses the "client" VM on my system, as you can see:
java -versionjava version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Client VM (build 1.6.0_01-b06, mixed mode, sharing)
I've made the server VM available by copying it from the SDK to the JRE's folder, though:
java -server -versionjava version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Server VM (build 1.6.0_01-b06, mixed mode)
What I would like to do, is set the server VM as the default VM. This is on Windows Server 2003 (which I use as a desktop), so I've gone to the control panel -> java -> java tab -> view java applet runtime settings -> added "-server" to the java runtime parameters. AFAICT this is only for applets though, and the java control panel doesn't contain anything to change runtime parameters for my desktop applications (e.g. netbeans, azureus).
What's the correct way to change the default VM? I'm interested in doing this on both Windows (2003) and GNU/Linux (Debian).
Thanks!

I figured out how to change it, posting it here in case anyone else wants to do this.
You simply need to find the file "jvm.cfg" and put this line above all others: "-server KNOWN" (no quotes of course).
On Debian GNU/Linux with Sun Java 1.5.0, the file in question is at /etc/java-1.5.0-sun/jvm.cfg.
On Windows, somewhere in c:\program files\java.
Edit: by the way, you can't have a blank line between the comments and the statements - this will give you an error.
To test if it worked, run "java -version" - it should say "[...] Server VM [...]".

  • Change VTP mode from Client to Server in a production VTP Domain

    Dear all,
    we have a production VTP Domain with some switches acting as VTP Client and 1 as a VTP Server. now the master is dead, and we would like to change the mode of one of the remaining switches from VTP Client to VTP Master. IMHO this change should not have any impact on the current configuration of the switches (and on the VLAN database), but we would like to have your opinion about this.
     Any help/feedback will be greatly appreciated
    thank you

    That should be fine.  The real difference between a VTP server vs. VTP client, the former allows (manual) VLAN configuration changes and the latter doesn't.

  • How to transfer passwords encrypted from client to server?

    Hello dear community,
    I have already some experience with programming and did a lot of web-software, but I never was facing the problem that passwords are transfered as plain text to the server when using a login-form.
    For my front-end, I use Java ServerFaces 2.0.
    I read a lot of hints like using a javascript based MD5 library and send the password as MD5 but this can be sniffed an decrypted easily.
    Do you have some hints to easily implement a secure transfer of values from client to server?
    best regards,
    Berni

  • Sending an object from client to server always on button press

    What I need is to send an object from client to server but I need to make server wait until another object is sent. What I have is the JFrame where you put the wanted name and surname, then you create a User object with these details and on button press you send this object to the server. I just can't hold the connection because when I send the first object, server doesn't wait for another button click and throws EOFexception. Creating the while loop isn't helpfull as well because it keeps sending the same object again and again. The code is here

    Current code fails because it's sending still the same entity again(using while loop)No it's not. You are creating a new User object every time around the loop.
    which makes the system freezeWhich means that you are executing network code in the event thread. Don't do that, use a separate thread. At the moment you're doing all that sending inside the constructor for ClientFrame which is an even worse idea: you can never get out of there to the rest of your client program. This is a program design problem, not a networking problem.
    and doesn't allow me to set new parameters of the new entityI do not understand.
    I need to find a way to keep Server running even when the client doesn't send any data and wait until the client doesnt press the send button again to read a new object.That's exactly what happens. readObject() blocks until data is received.

  • Date converting to less one day while transferring from client to server

    Hi,
    I have very typical problem. My application is in java, we are using oralce 9ias. The problem when the server is running in german locale and client is running in english. We the date value is passed from client to server it is converting to one day less.
    i.e.
    If i want to search with records jan 02,2005,
    on server side if we print the value it is getting as jan 01,2005.
    Can anybody help me in solving the above problem.
    Its bit very urgent.
    Thanks in advance
    regards
    Kalyan

    well, i have had nightmares with this problem. here are the reason and soln:
    reason:
    in ur DB, u r using a field "Date" which does not include time information. Hence, any date will be taken at 00:00:00. If such a date is opened in some other timezone, which is ahead of the server timezone, the date differs by one. This is becoz java always considers the millisecond info encapsulated in the date, calendar.
    soln:
    Step 1:
    u must be able to get the "timeZoneOffset" from a calendar object. This timeZoneOffset will give the number of minutes/seconds/hours... by which the system is offset from GMT.
    Thus if u create a calendar in India, the timeZoneOffset will be 330. If you create the calendar in UK, it will be 0.
    To achieve this, we have made an object-UTCDate. This class encapsulates a Calendar. It has a function called "getTimeZoneOffset".
    Step 2:
    Once u get the timeZoneOffset, here is what u need to do in ur code. (assume that the timeZoneOffset is in minutes. the variable names will be self-explanatory)
    at the client side code:
    long timeInMillis = calendar.getTime().getTime() + (timeZoneOffsetOfTheCalendarReceivedFromServer * 60 * 1000 ) - (timeZoneOffsetOfClient * 60 * 60 )
    use timeInMillis to make a new Date Object and use this date object.
    at the server side code:
    long timeInMillis = calendar.getTime().getTime() + (timeZoneOffsetOfTheCalendarReceivedFromClient * 60 * 1000 ) - (timeZoneOffsetOfServer * 60 * 60 )
    hope this helps.

    <Side A>
    You'd just need to write an application that doesn't have a GUI (so, a console-based application) that listens on some pre-determined port for a message to start broadcasting. Maybe you'd send it the IP/PORT number to start broadcasting on. Once it receives that message, it'd start broadcasting the web cam to the IP/PORT number until it received a message to stop. Once it stops, it'll just go back to waiting for the next "start" signal.
    <Side B>
    On the other side, you'd write an application that sends the start messages, receives/displays the videos, and then sends the stop signal. This will have a GUI, and be your "control program" so to speak.
    Then, once of have both of those programs working...if you're using Linux, you're done. If you're using Windows, you'd need to modify the <Side A> program so that it can run as a Windows service.
    There are a lot of ways to do this, you can google it or look at the following link:

  • How to deploy Forms, Reports and Menu from Client to Server machine

    Dear Experts,
    I have one requirement to deploy the Forms, Reports and Menu from client machine to server machine.
    Deployment involves the following steps :
    1. Firstly we have to search the selected file in a folder where the .fmx is present ( in Server machine) and take the back up of the the existing file in the server (Source and destination paths will be available).
         Ex. If the existing FMB name is TEST.fmx then the backup file should be TEST_sysdate.fmx.
    2. Secondly we have to transfer the file from the client folder (or from another folder of the same server) to the server folder where the back up exists.
    Please help me to search/rename/copy/replace the _.fmx/.rdf/.rep/.mmx_ files from client to server.
    We are using
    9i Database.
    10g Forms and reports.
    SQL Developer tool.
    OS is Windows (Client and Server).
    Help me out to attach a file of front end screen which we are planning to develop. It will give a clear picture on this requirement.

    Welcome to the forum. Please take a while to go through the FAQ to be found to the top right of the page.
    Your issue is more to do with batch files rather than Forms. The only relation with Forms, as I see it, is that you will be using HOST/CLIENT_HOST to start a batch file with the file name to be deployed as a parameter passed to it.
    You need to rewrite either a CMD batch file or a Powershell script to achieve what have set out to do.
    For CMD batch files look up http://www.robvanderwoude.com/battech.php , or any of the other excellent resources available on the internet.

    They haven't been checked as Solved, it's an option for you to choose one if the answer has solved your problem. You can mark one answer as Solved, and two as helpful. Only you, as the originator of the topic, can see these buttons.
    Sorry for the goofed answer. Most people are looking to set the margins and I looked over that you were interested in the tabs.
    To save tabs in fixed positions that will appear with every new document, you must modify the default template. You can't open the template from the desktop. If you do, it will open as a standard document. You must open it from the Open dialogue box from within Word. With Word in the foreground, press Command+O and navigate to:
    /Users/your_account/Library/Application Support/Microsoft/Office/User Templates/
    Open the file Normal.dotm
    Set your tabs and save the file. Close the template. All new documents will now open with those preset tabs.
