Java Runtime Parameters patch

I currently have a signed applet which uses more than 96MB. To solve this obstacle I want to increase the memory heap. Is there any way, from a signed applet, to alter the Java Runtime Parameters? Ofcourse the user can alter the parameters but I want to take that trouble out of his hands. I am hoping to run a small "patch-applet" which adds the "-Xmx xxx" parameter to the JRE.

After Java VM is launched, I don't think it is possible to change the classpath onfly. If you goal is to load test.jar on fly, you can always rely on classloader to do it. You can make your own classloader and let it to download and define the class you need.

  • How to set plug-in Java Runtime parameters on JRE setup command line

    Hi all:
    I need to install JRE and set the Java Runtime Parameters -Xmx
    by command line ..
    I mean I don't want enter Control panel and set this parameter manually in Java Runtime Parameters textBox..
    thanx.
    Best regards
    w.shiha

    Documentation for controlling the installation is sadly lacking in detail. This is the best I have seen for the Windows environment:
    http://java.com/en/download/help/silent_install.xml
    But, there are numerous other PROPERTY variables that are not discussed. Particularly annoying is the addition of yet another JavaUpdate item with the release of 1.5.0_05. If you can get more information, please post a link to it here.

  • JRE 1.4.2 Java Runtime Parameters

    Does anyone happen to know where/how these settings are saved on a Windows OS? I'd like to write a program to automatically set this on client machines to make deployment easier as we need to set the -Xmx for each user. I've searched the registry and all files on my machine and turned up nothing. Thanks for any help/suggestions you might have.

    The settings are saved in a file named
    <windows
    folder>\.java\properties<version>e.g.
    C:\WINDOWS\.java\properties141_02. The keyname
    is javaplugin.jre.params=<runtime params>.You
    can see this directly, if you change the runtime
    parameters in the Java plugin configuration dialog.
    What version of Windows are you running and what JRE
    version..only b/c it would be helpful to know if these
    settings are saved in different locations depending on
    versions. On Win2K Pro & XP Pro w/ JRE 1.4.2 the
    settings are in the location I specified in my last
    post. Thanks!Sorry, I only checked 1.4.1
    My (wrong) idea was, that it wouldn't change frome 1.4.1 to 1.4.2

  • Java Runtime parameters- setting trace/log levels and enabling by default

    Hi,
    I have a user reporting that a Java app that I support is unexpectedly quitting, and our developers are having trouble tracking down exactly what's causing the problem.
    I'm trying to enable the maximum possible logging/tracing for this user, but I don't want to have to rely on them remembering to hit '5' on the console window to enable tracing on everything. Having read through the runtime documentation, I have added the following to my JRE runtime parameters:
    -Xdebug  -Djavaplugin.trace=true -Djavaplugin.trace.option=basic|net|security|ext|liveconnect -Djavaplugin.outputfiles.overwrite=falseHowever, I still get nothing in the log file until I manually hit '5' on the Java console, then everything I do after that gets added to the log.
    Does anyone know how can I get the maximum logging/tracing enabled by default as soon as the JRE is loaded?

    >>
    -Xdebug  -Djavaplugin.trace=true-Djavaplugin.trace.option=basic|net|security|ext|livec
    onnect
    -Djavaplugin.outputfiles.overwrite=false
    One problem is that -Djavaplugin.trace.option=basic
    OR net etc ... pick one of the options which are
    separated with pipe symbols or use "all" without
    quotes.
    I'm having a similar problem with Java 6 - it seem
    that nothing I put in the runtime parameters takes
    effect. I had to edit
    /home/USERNAME/.java/deployment/deployment.properties
    and add deployment.trace=true.On second thought, I could be wrong about the trace options. I really don't know if you can combine options but I did see "all" somewhere.

  • Java Runtime parameters at System tab

    Did install Java Runtime 1.6.0.18 silently, for many workstations, but after install I checked "Control Panel/Java". The "System" tab i "Java Runtime Environment Settings" are disabled, and can not be revised. How can System tab be enabled? (User tab is OK)

    I think this has been discussed previously in a thread on this site.

  • Setting Java Runtime Parameters from HTML

    I am launching a java program from HTML, using java plugin 142_08, and I need to set -xms and -xmx in the java plugin from the HTML that is launching the program. Is this possible to do? It is used by many various people, so it won't be easy to go into everyones computer and manually set these params.
    Any ideas?

    There will soon be a solution available for this problem. There is an early access program for the "6uN" consumer-focused release of Java at http://jdk6.dev.java.net/6uNea.html . Build 08, which should be out in a few days, will contain as an option a new implementation of the Java Plug-In which supports what you want. You will need to go into the Java Control Panel, Advanced Tab, Java Plug-in node, and enable it, then exit, to turn on the new plug-in. At that point you will be able to write in your applet tag
    <param name="java_arguments" value="-Xmx128m"></param> for example. It has the same notion of "secure" command-line arguments as Java Web Start; using "non-secure" command line arguments requires a signed applet, but unsigned applets can utilize secure command line arguments and system properties. More documentation will be available on the new Java Plug-In soon.

  • Multiple Users on one PC sharing Java Runtime Parameter setting

    Is there a way to have mutiple logins share the -Smx512m setting in Java Runtime Parameters. It seems that when each person logs into the PC to use the application we have to enter the same Java Runtime Parametes again. Is there a way to add it once and every login uses it?
    Thanks,
    DLS

    I have read the Deployment Configuration file and Properties and do not see how the -Xmx51m should be added to the deployment.properties.
    Also it would seem you would need to use the deployment.system.config file so it would be used by all users on the PC.
    Again I can not see an example of how to put in the "Java Runtime Parameters" in the deployment.system.properties file.
    Has anyone done this before and could lead me in the correct directions?
    Thanks,

  • Java runtime parameter (-classpath)

    Hi,
    Does anyone know how to programmatically set the java-runtime-parameters?
    I need to set them to: "-classpath c:\jar\test.jar"
    My goal is to access test.jar thru the ActiveX Bridge, and test.jar is not inside the "applet" folder (nor the "ext" folder). Note: ActiveX bridge uses the java plug-in which has a default path to the applet folder, I need to programmatically set a java-runtime-parameter "-classpath" to c:\jar\test.jar...

    Gene.

    People I have tried this after trying all that I could fine on the internet,
    What did not work is as follows:
    1) Setting "-Xmx512m", where "512" should be replaced by 3/4 of the system
    physical memory size.
    2) Also enable "<APPLET> tag support" for Internet Explorer. Apply settings.
    This worked for some.
    3) Also tried uncheking the box for <APPLET> but that was not to work.
    "What --WORKED-- for me at last was:"
    1. Uninstall Internet Explorer 7.
    2. Restart System.
    3. Uninstall Java 1,5 with Update 9(that was installed)
    4. Install Java version 1.5 with upgrade 5 from the link:
    http://www.tucows.com/preview/194327
    5. Then go to Start, Run, type
    iexplore
    and hit Enter.
    Try the sites now.. It works:)
    6. Then disable update for Java in Control panel. (Also do not update IE or
    JAVA after that)
    Hope this help ya all!!!

  • How to redirect "-verbose" Java Runtime Parameter setting to text file

    Simple question: I am adding a "-verbose" Java Runtime Parameter in the Java Applet Runtime Settings of the Java Control Panel. When I run my applet, a Windows console opens which outputs all the method calls, classes, and jar file information. How can I redirect this output to a text file?
    I noticed Xloggc:+filename+ but there does not seem to be an equivalent for redirecting the '-verbose' output to a file.
    Thanks!
    Edited by: zillius on Dec 14, 2007 1:47 PM

    Thank you both for the reply, but unfortunately that is not quite what I am looking for. The console Window I am talking about is a DOS console screen, not the Java Console
    What I am really after here is the ability to redirect a thread dump of a running applet to a text file. When the applet is active, and the "-verbose" parameter is set in the Java Runtime Parameters", I can see all the classes, methods etc. being loaded in the DOS window. Hitting Ctrl-Break at that point will produce a thread dump in the DOS console screen. I would like to be able to redirect THAT output to a text file. It is not in the Java Console. To me it looks like tracing and logging are only for the Java Console, no?
    Thanks again for your help.

  • The Java Runtime Environment cannot be loaded

    When viewing my website I get the above message. I click on ok, go into the site, but when changing pages I get the following "several java virtual machines running in the same process caused an error". On other computers there is no problem. The website was developed using Serif WebPlus 10 on Windows XP SP2.

    The Java Runtime Environment cannot be loaded, followed by multiple java machines in the same process causing an error. I had the same thing happen to me in IE version 7. Eventually I did a few radical things to fix the issue. One of the things I did, or combination of things, eventually fixed it. I'd close and re-open IE7 with each different thing I tried so as to reset it. I uninstalled every Java RTE update, and there were about 5 of them, and then reinstalled the latest (1.5 Update 10). I turned off Tabbed browsing (once it was fixed I turned it back on). From MS Control Panel - Java, General Tab, Delete Files... I deleted everything Java cached. From the Java Tab, View... Button, I removed all Java runtime parameters for the 1.5.0_10 line so it just starts up with defaults. (Basically undoing memory parameter fixes another thread said to try, I typed in to try and fix it, and this did not work "-Xmx256M" this setting caused more harm than good). Well, that's what I did, and now I can browse websites with Java again. It's probably a little radical, but the error message wasn't very helpful in pinpointing what exactly caused the problem in the first place. Good luck.

  • Where are Java Preferences (Applet Runtime Parameters) saved on Mac OS X?

    Hi.
    If you want to modify the Applet Runtime parameters in Mac OS X, you need to use the "Java Preferences" application located under /Applications/Utilities.
    Suppose that I open the "Java Preferences" application, I select a specific JRE version, and I set a runtime parameter of "-Xmx300m" for Applets, in order to increase the max heap size.
    Now, where is this setting saved to?
    Until recent past, these values used to be saved in the <UserHome>/Library/Caches/Java/deployment.properties file.
    But this does not seem to be the case any longer.
    Does anyone knows where are these settings currently saved in Mac OS X? I am currently running Mac OS X v10.5.8 with Java 1.6.0_20 installed.
    Any help / hint would be greatly appreciated.
    Thanks,
    Marco.

    Check this out:
    http://developer.apple.com/documentation/Java/Conceptual/Java141Development/Core_APIs/chapter_6_section_3.html
    Hopefully that all fits on one line. Click around that website for just about any Mac-specific info you'll ever need.

  • How to override runtime parameters of Java programs in web browser windows?

    Hi Oracle forumers,
    There's a Java based program that is accessed through a web browser. The program somehow sets its own runtime parameters. However, those parameters don't always work well for running the program on every computer. Is there a way to override the runtime parameters that the program would normally set with my own parameters? I was expecting the Java Control Panel applet to be the place to set my own runtime parameters but the last time I checked that didn't work with this program.

    Sangeetha Kalyani,
    Use SWF de-compiler.. and get the source of your SWF.. i think this will simplyfy your JOB...!
