When does java start

I would like to know when java starts upon reboots of Solaris machines. I cannot seems to find any startup scripts in the rc directories. Any ideas?

FWIW, Solaris and Linux don't do any reboots (or
anything else nasty) during WS install.

  • When does java deallocate memory for objects;

    um i'm working on a midp application that is very memory consuming. i would like to optimise it and make it just the oposite of what it is. now i would like to know when does java dellocate memory for an object, is it when it can find no more references to that object? or some other time, well i know its not when it can find no more references to that object because i've already tried that.
    or to make things simpler is there any explicit way to make java deallocate memory for a specific object, like if i have a thread, which is executing a while loop, and i want java to end the thread and free its memory. is there any way to do this?

    I happen to have quite some J2ME experience and it's not overly wise to count on extensive garbage collection. The garbage collector in limited device VMs isnt as advanced as it's big brothers. Try to avoid excessive object allocation and reuse instances whenever possible.
    As for garbage collection, objects will be garbage collected if they can no longer be reached by any of the active application threads and if the garbage collectors deems it necessary to collect garbage, which will probably be when free heap memory becomes sparse or when there's some idle time in your application.

  • When does Java Web Start install want to reboot?

    Hi,
    I'm installing JWS 1.0.1_02 and at least in one case I'm seeing that the install wants to reboot the machine during the install process. I'd like to avoid that if possible, so I would like to understand in what circumstances the install process wants to reboot the machine.
    I've seen references in other topics regarding the use of the javawebstart dll that causes a reboot, but I don't think it is the case here.
    I have a machine that is W2K that I've installed numerous times and the install has never asked to reboot. I have another machine that is NT that it seems to always want to reboot.
    Is it related to OS type? (I need to install on W2K, NT, and 98)
    Is it related a running JRE version?
    Is it related to a dll running?
    Are there other forces at work?
    Any help on this would be greatly appreciated.
    Thanks,
    Beth

  • When does Web Start try and connect to Sun

    How can I make it so web start doesn't try to connect to sun ever? I want it to check for updates only to our application and I don't want it to try and access the Internet. Thanks.

    I've heard the JWS installer looks in the Windows Registry for already installed Java Runtime
    Environments (JREs), version 1.2.2 and higher, and automatically configures Java Web
    Start to use them and that it also installs version 1.3.0_03 if it is not there. Does this mean that if I already have that version installed it won't go out to Sun's website? It seems to me that after JWS is installed it tries to access the internet each time it is run. Anyone know?

  • When does Java load classes?

    Hi there,
    I have a question about when Java is loading class? Does it load the class when use it or it will load all classes in the scope in one shot?
    Let's say I have a projectA java program which has classA:
    class classA{
    I have a jar file: my.jar which uses classA if it is used in projectA:
    class myClass{
    if( enviroment.equals("projectA") )
    classA a = new classA();
    This works no problem.
    Now let's say I have another program call projectB, which does NOT has classA; Now, can I link my.jar to this projectB and run??
    Thanks

    Java loads classes only upon access.

  • New iPhone - when does service start?

    Just picked up a couple new iPhones - one for me, one for my wife.
    The guy at AT & T store said it would take a few hours before we were able to use the phones...well, it's been 5-1/2 hours now and no service. Is this normal???

    Did you port your number over from a different carrier? If so, when I got my iPhone the guy said it can take up to 3 hours for it to complete but mine took 1 1/2 days before everything was complete. Until then I had to use my iPhone to make calls and my old phone (Verizon) to receive calls/text messages.
    It was only a matter of minutes before my iPhone was activated however (able to make calls from it).
    If you're not in the same situation then I'm not sure what to say except wait it out, maybe the AT&T servers are chugging along slowly but surely tonight.

  • When does the tick count start

    I see that the tick counter rolls over at 2^32 ms, that's 49 days.  So if the counter started when Labview or the VI starts, I would never care about the rollover. 
    So when does it start?  Can I control when it starts?     I need a resolution less than 1 sec, so the second timers don't help me.
    Also do other funtions or VIs continue to operate when a Wait (ms) function is running?

    The tick count does not begin when you open LabVIEW or the VI. The on-line help says that the base time is undefined. There is however, no problem with you taking the tick count when you first start the VI and using that later in the VI. It's also untrue that the other time functions in LabVIEW only have 1 second resolution. They have the same millisecond resolution as tick count. If you have code in parallel with the Wait (ms) function, they will exeucte in parallel.
    Also, in the future, post questions of this nature to the LabVIEW board. This board is for the NI counter/timer boards.

  • When does GC happen

    I used -verbose:gc flag with java and found that GC seems to happen too many times, as I see a big number of stmts like
    [GC 5829K->4727K(130816K), 0.0299689 secs]
    As you can see there is no need of memory(130k is free), so GC is not really necessary. My question is, when does Java do GC? The answer might be different for JDK 1.2, 1.3 & 1.4, I have started using 1.4 now.
    Thanks.
    santosh

    why would my code depend on GC time? Usually it doesn't, but some programs are depend on running consistently without stopping execution at random times to run the garbage collector.
    Here's an example. Suppose you were writing a program that controlled a robot like the honda p2 (http://world.honda.com/robot/), and more specifically how to make the robot walk down stairs. Now the robot can make a step, and in mid stride it could run the GC. If the robot is not balanced when the GC runs, it would fall down & break. You would need to controll when the GC runs so it only runs when there is no movement.
    Now this situations does not apply to most people, but it demonstrates the point that for some programs the execution time is critical, and the GC could cause serious problems to the entire system if it executes at bad times. A few months ago I saw a post from a person who had problems with this very thing.

  • Applet does not start after Java 1.5 installation

    Hi,
    When I go to my webpage where I have an applet that requires Java 1.5..the browsers are prompting for Java installation (ActiveX component install on IE or Firefox plugin for JRE installation). But once the Java install completes the applet does not start automatically. The same code used to work nicely with Java 1.4. The applet used to automatically start and run once the JRE install completed. But with JRE 1.5 it does not start. If I do a refresh on the browser it again prompts for java installation. If open new browser window and go to the URL the applet starts. Please let me know how to get the applet to start automatically after JRE 1.5 installation.
    Thanks,
    Vijay

    We figured out the problem. the CLASSID was not the right one. Once we changed it...its working fine.

  • J2EE Does Not Start During JAVA Add-In Installation

    I'm installing Java Add-In onto ERP 2004 (Windows 2000, Oracle 9.2, Java 2 SDK 1.4.2_08).
    The J2EE does not start during the installation. It gives up after some time. java -version shows the correct path.
    dev_jcontrol shows the following:
    [Thr 2624] Tue Aug 02 09:49:32 2005
    [Thr 2624] JControlExecuteBootstrap: execute bootstrap process [bootstrap]
    [Thr 2624] [Node: bootstrap] java home is set by profile parameter

    [Thr 2624] JControlCloseProgram: started (exitcode = -18)
    [Thr 2624] JControlCloseProgram: good bye... (exitcode=-18)

    In that case, do u have multiple versions of JDKs installed ?
    Maybe some earlier version is installed too ! In that case there is a program that comes along with the JDK to choose the version of the JDK that needs to be loaded into memory.
    We faced this problem when we were doing our stints with JAVA Add-In wherein the system required the newest version of java where as some tool which was installed on the system required the older version.
    So we used the java program to select the version to be loaded whenever the operating system tried loading the jdk.

  • When does a value help in Java webdynpro 2004s get created automatically

    HI All
    when does drop down value help get created automatically (without coding) in java webdynpro NW 2004s application for a view field mapped to a abap dictionary like currency(Domain:waers) having a value table  TCURC but has to be created for a field like UOM(Domain:meins) having a value table T006
    the only differnce I can see in the 2 domains in my current set up is, meins has a conversion routine & wears doesnt
    this is a question that applies to both java webdynpro & abap so please dont ask me to post it in another forum.
    Im sure some one has asked this question before. please guide me!!
    Thanks
    Prasad

    Question:
    If I start a java thread from the �main� thread of
    execution and that thread I just created finish�s
    executing its �run� method is that threads resources
    automatically clean up? Or do we have to do this
    clean up ourselves?Depends which resources you mean. There's nothing special about threads in that respect.
    Memory is automatically reclaimed when it is no longer reachable, so unless the run method set some member variables in some object that remains reachable after it completes, no worries there.
    Files, sockets, etc. remain open unless you close them.
