SYSTEM PROPERTY IMPLEMENTATION IN JVM

I want to know how the system properties like java.version, java.compiler is implemented. I once found out the source code in JDK 5.0 distribution from JRL that in System.initProperties native method, some of the system properties are initialised but i want all the system properties.

I want to know how these system properties work too, interested.

  • How does JVM set file.encoding system property?

    The system property file.encoding is changed mysteriously, and we don't have a command line -D option. How does JRockit JVM get the default value for system properties such as file.encoding?
    I am running Jrockit 1.4.2_12.
    Thanks.

    I am running WLS 8.1SP6 on Linux using Jrockit 1.4.2-12. Over the weekend, I bounced WL server, and file.encoding was changed. It used to be ISO-8859-1. Now it is ANSI_X3.4-1968. Neither System Administrator nor WebLogic (farm) Administrator changed anything. Although I can force it with -D, I'd like to figure out what happened.
    Thanks.

  • Setting a system.property twice in a same JVM

    Hello,
    I have got a problem concerning the setting of a system property.
    When I run a first time my program I test a case by setting a system property, that works fine.
    Now I want to change the same property in the same JVM by doing:
    System.setProperties("key","oldvalue");
    System.getProperties("key", "oldvalue"); //I obtain oldvalue
    System.setProperties("key","newvalue");
    System.getProperties("key", "newvalue"); //I obtain newvalueBut apparently it seems the JVM doesn't take the new value of the property even if the getProperty() give me the new value.
    So my question is can I change several times the value of a same property in the same JVM or it is technically not possible?
    I read the tutorial about System and it says :"The setProperties method changes the set of system properties for the current running application "
    Thank you for any assistance

    And I say that it apparently does not work because I run some tests
    to find why my results were wrong even if in setting a new property.Well, one of those tests might be to just check the changed property right after the change.
    Which you do in your code.
    And which results in a correctly changed property, doesn't it?
    So, what are those other tests you've performed, what was it that you've expected them to do and what did they actually do?
    So it is just because if you have initialized the system property once you
    cannot do it again or you have to record the new value in a file and then restart
    your application by take the value of the system property inside the previously created fileNone of both. You can just change the system properties (just like every other properties) and the changes take place immediately (unless you run multithreaded, in which case you should put the "setproperty" stuff into a synchronized block or method.
    Of course, if you try and change the properties of your operating system, then that's different. But I won't start and guess around about what exactly you try to do and what does not work.
    Again, try to state plainly
    1.) what you programmed, perhaps with some line of code
    2.) what you expected your code to do
    3.) what happened instead
    Provided with that information, forum readers should be able to provide you with some help.

  • Coherence Extend: is remote address a JVM/System property?

    Hello,
    I want to pass remote address and port as a JVM argument (not really being part of the cache configuration of the extend clients), is it possible?
    <remote-addresses>
    <socket-address>
    <address>192.168.0.2</address>
    <port>9099</port>

    is it possible to Dynamically inject the Address into the cache configuration file?
    <socket-address>
    *<address>{IPAddress}</address>*
    <port>9099</port>
    </socket-address>
    </remote-addresses>
    Thanks
    Prab

    Hi Prab,
    You do it like this:
    <socket-address>
          <address system-property="my.extend.address"></address>
          <port system-property="my.extend.port"></port>
    </socket-address>You then specify the properties when you start up
    -Dmy.extend.address=192.168.0.2 -Dmy.extend.port=9099JK

    Thank you

    Hi,
    Thanks. But its not possible for us to move to SE 6. Right now we are in JRE 1.5. Is there any other way to pass mulitple/dynamic arguments to the Applicaiton. We will be using only the javaws command line only to invoke the remote application by passing the url(jnlp_url). So we need to pass mulitiple command line arguments to the application through javaws.

    try to look on xml.apache.org for this error. There should be some pages describing how and why setup this property.
    Basically, these properties defines factories for javax extensions. javax defines interfaces and providers than supply implementations, so for example you can use different XML parsers implementations (we use Xalan for one OC4J container and original ORACLE parser for other). To bind this together they use some defined mechanism like setting system property of including special manifest file etc. (I don't know about details)

  • Java.system.property

    I repost Craig Sandin's question, which was post on Feb 06th. I have the same problem
    as him.
    I have used java.system.property in my wls 5.1 weblogic.properties file, and it
    set a system property I could get at runtime. Is there an equivalent in wls 7.0?
    I haven't found anything in the documentation for config.xml. Obviously I can
    pass -D options to the jvm, but I was looking for a way from the config file.

    We don't offer this anymore.. Sorry.
    You could write your own very simple
    wrapper class to start WLS:
    Properties props = new Properties();
    props.load(new FileInputStream("weblogic.properties");
    System.setProperties(props);
    weblogic.Server.main();

  • Problem with file.encoding system property

    Hi all
    I develop a web application with Tomcat app server.
    I have to set file.encoding system property to "Cp1252", but when I set it programatically using System.setProperty("file.encoding","Cp1252") it doesnt affect to my program outcome but when I put it in catalina.bat with set JAVA_OPTS=-Dfile.encoding=Cp1252 it works fine.
    what is the differences and why I cant change that property programatically?
    thanks

    why I cant change that property programatically?It is a system property reflecting the initial settings read when the JVM started. Resetting the system property java.home will not change your home directory either.

  • System property that represents a user's My Documents folder

    Hi! What is the System property that points to a user's My Documents folder on Windows platform? Thanks!

    >
    Define "only".
    I would imagine that there is a highly finite number
    of file configurations on all Win OS 9x onwards and
    System.property("os.name"); would resolve this with
    only a few additional lines of code.
    Actually, that's not true either... In Win 2K and above, the My Documents folder can be located in an almost infinite number of places, that are then mapped to a virtual My Documents folder.
    This can include network locations (in the case where a user's Windows profile is stored on a central server instead of on each workstation), or with phyisical names other than "My Documents". For example, when using Win XP to connect to an Active Directory hosted on a Win 2003 server, the phyiscal location of the My Documents folder is actually named with the user's name - i.e. "John's Documents".
    Even better, the name that is selected is not always the Windows login name - but could also be the alias that the user has created for themselves.
    Anyway, here's the point: If you want your code to work on all Win platforms (today and in the future), you have to get the directory the way the Windows API says you have to get it: using the SHGetSpecialFolderLocation function. If you want to try to hack something together, then it might work in a lot of cases for a little while. But it is going to break at some point. Personally, if I know a piece of code I'm writing is going to cause my app to break in the future, I write it differently so that won't happen - but that's just me.
    There's probably a way to find this info in the registry as well, but there is no guarantee that the location this information is stored in the registry will remain the same - if it changes, then the SHGetSpecialFolderLocation implementation will change.

  • How to display system property in XML forms

    Hi
    We are using XML forms template for publishing news in KM. In the show form we got author field (a label in the form) which is mapped to system property createdby (PropertyReference = /Properties/default:createdby).But while displaying the form author is not getting populated. When I try to edit the form in XML forms builder in data model tab under properties node no property is visible. Nothing is shown up in properties even after reload option is selected from context menu of properties node.
    I cheked by manually editing PropertyReference to some other property (e.g. modifiedby) but nothing is showing up.
    Can you please suggest how the createdby system property can be shown in the xml form?
    Thanks & Regards
    Sudip

    Hi Sudeep,
    Please try to open the formbuilder in another machine and try to see the properties xml form design view.
    You can even directly can create a lable in show form and add the property name along with the nama space name.
    For default properties namspace is default.Create a lable UI element in show form and select the datasource property and add the property value in that.
    With we can show file related system generated properties in show form.

  • Can you set a global EntityResolver (via system property, or static method)

    I'm trying to set a customized EntityResolver (telling the xml parser where to look for XML schema files).
    Usually, you'd use the standard syntax - somehting like:
    SaxParser parser=new SaxParser();
    parser.parser.setEntityResolver(myResolver);
    However, I was wondering whether you can set a "global" EntityResolver, to be used as default for all parsers ?
    Maybe this can be done through some system property, or a static method somewhere in the parsing XML ?
    (BTW, I need it because I'm using some third-party API, that encapsulates a SaxParser, but won't let me access it, so I can't configure it directly).
    thanks.

    I don't think you can.
    What is possible is to set content on the folder resource itself; that would be returned instead of the page you mentioned.

  • Is their a way to set system property in weblogic console

    Hi WL USERS
    Is their a way to set system property in weblogic console ie (http://localhost:8080/console) ? if yes, can we access that property in code using System.getProperty()?
    Regards
    vishy

    Yes, It is Possible.
    Please check the Option-1). Mention in the Following Link: http://weblogic-wonders.com/weblogic/2010/03/26/nodemanager-based-managedservers-setting-mem_args/
    Here i tried to set a Custom Property "*-Duser.dir=E:/MyDirectory*" through the Admin Console.
    NOTE: Setting any Option like JAVA_OPTIONS/CLASSPATh etc through Admin Console will work only when you start your Servers using the NodeManager. It means when you start your ManagedServers through AdminConsole...or Using nodeManager based WLST scripts.
