Is it possible to access system api using java

can i catch the processor( Intel Processor) id (unique no. for each processor provided by Intel)

Not in pure java. Try using native libraries.

  • Access System Resources using Java Applet via Java Script

    Hello
    I can access my Applet public methods (and this methods access system resources) via Java Script if I do the following: System.setSecurityManager(null);However, I'm making this post because I don't like this solution.
    Supposedly, setting the SM to null is like making the Applet (which is signed and was accepted by the user via a prompt from the browser) behave like a normal Java program that has no restrictions. (http://java.sun.com/docs/books/tutorial/essential/environment/security.html, second paragraph)
    However, this feels like a workaround of something that is supposed to be there (the SM).
    Also, if I make the methods invocation from inside the applet (using swing buttons and textboxes for example) I can use the standard SM without no problems.
    From my readings, the problem regarding Java Script invocation, comes from the fact that the Java Script is not a secure (not signed) source (because you can invoke public methods the way you wish from it i guess) on the contrary to the applet methods invoked by the buttons.
    Possible solutions I found in the web range from using the public static Object doPrivileged(PrivilegedAction action) method or imaginative things like creating new threads on the public method that call the private methods that access the system resources (supposedly because the new thread runs under the safe environment of the applet)
    I almost got a glimpse of hope with this post http://forums.sun.com/thread.jspa?threadID=5325271&tstart=0
    However, none of these solutions worked, the only results were with the setResourceManager(null)So, any one can contribute with a solution for this? Should I keep trying to find a solution other then the one I already have?

    1. yes
    2. yes
    Note for 2. the converter will run the applet with SUN jre for sure if the user has IE.
    IE will use the ActiveX technology to run the applet (as with Macromedia Flash).
    For Netscape I am not sure, but I would think Netsape will use the plug in provided by
    SUN.
    Note for SUN jre 1.3. If this applet is to be used within a company that uses a proxy with
    ntlm authentication the 1.3 applet cannot connect (to the Internet) through this proxy since
    ntlm athentication is supported since j2re1.4.2_03. There is one version before that but
    that one will pop up a window asking for the user's domain account and password wich
    is both lame and crappy.
    As for the IE settings, IE has a default setting that askes users the "do you trust"
    queston for AciveX controls within the Internet securety zone (tools -> internet options
    -> security).
    Sincy anybody can make ActiveX controls (allso sign them) a user that has a problem
    to find the "no" button will sooner or later install a malicuous ActiveX control (spy ware
    or a virus).
    If this user's desktop is within your company's network it will cause serious harm.
    This is why most company's disable this by changing the default internet expolorer
    settings. Since I assume you are writhing this applet to be used by a company I allso
    assumed that company has someone to maintain the desktops. In that case I
    assume that person would want to control the security within the SUN jre instead of
    letting the user deside what to trust and what not.

  • Stoping System Clock using Java code.

    Is it possible to do so if yes then some code idea for
    Stoping System Clock using Java code.
    [email protected]

    The system clock is controlled from the BIOS, and as such, I don't think even windoze can stop it, though it can be continually reset. I don't believe that Java provides a sufficiently low level of control to set the system clock, although you could use a native method to accomplish the task.
    Why would you want to do such a thing?

  • Can i change system time using java

    hi guys can i change system time using java iam doing one app in that i have to change the system time (my os is windowsXP) please tell me how to change the time

    What does this have to do with Swing?
    Well, there is no Java API that I'm aware of.
    However you can execute any Windows command by using the Runtime class. So you should be able to invoke the Time command.
    Search the Java Programming forum. There are plenty of examples on using the Runtime.exec(...) command.

    How to read system eventlog using java program in windows?
    is there any java class available to do this ? or any one having sample code for this?
    Your friend Zoe

    Hi,
    There is no java class for reading event log in windows, so we can do one thing we can use windows system 32 VBS script to read the system log .
    The output of this command can be read using java program....
    we can use java exec for executing this system32 vbs script.
    use the below program and pass the command "eventquery"
    plz refer cscript,wscript
    import java.io.*;
    public class CmdExec {
    public static void main(String argv[]) {
    try {
    String line;
    Process p = Runtime.getRuntime().exec("Command");
    BufferedReader input =
    new BufferedReader
    (new InputStreamReader(p.getInputStream()));
    while ((line = input.readLine()) != null) {
    System.out.println(line);
    input.close();
    catch (Exception err) {
    err.printStackTrace();
    This sample program will list all the system log information....

  • How to access sharepoint logs using Java?

    Is there a way to access Sharepoint logs using Java from a remote machine? 
    Any help / pointers would be appreciated. Thanks.

    Hello,
    I am not aware about any client modal class for log but if you create your own service and host in SP server then you can call this web service in JAVA. (i am not sure whether JAVA supports .NET web service or not).
    You can refer this for web service:

  • How to access Websphere variables using java

    Hi
    I want to access Websphere variables using java.
    Any help is appreciated!!
    Thanks
    P

    WebSphere Application Server has a bunch environmental variables such as log locations. These are held at the "server", "node", and "cell" level.
    To access them, you have to get the right context. Something like this, I believe...
    InitialContext initialContext = new InitialContext();
    initialContext.lookup("foo:bar/baz/blah"); //correct context hereGo to the IBM website for WAS and do a search on namespace bindings. That should give you some more information.
    Good luck.

  • How can i get system variable using java

    Hi,
    I just want to know how can i get system variables using java code.
    for example i want to get the the date for today or i want to get the number of processes that's running.
    Thanks alot

    Hi,
    I just want to know how can i get system variables
    using java code.
    for example i want to get the the date for today or i
    want to get the number of processes that's running.
    Thanks alotSome generic "system variables" are available though Java, usually through the System class.
    Date today = new Date();
    is instantiated with the current date and time.
    Other system values, like environment values, should be passed to java through the command line (-D option) by setting system properties.
    Finally, platform specific values like the number of processes running will have to be written in platform specific code and executed by JNI (java native interface).
    Java is platform or system agnostic. Common system values, like time, are implemented. Hopefully you won't need platform specific values.

  • Access mirror site using java, download files and other information?

    Hi, I have 2 nodes/servers on the system both running webservers and having the same interface, but at a time user will access one node at a time from their browser, but this interface will be able to allow the user to get information from the both the nodes. the information that the user can get is DB stored as well as files on the disk of either node.
    i can manage the DB, cuz there is nothing to it, but how do I get files from the other node?
    currently any files/web documents are all stored in a application directory of the web root and protected by htaccess i believe, so when a user logs on to node one he can access all plain text/binary files along with web content since the web server authorizes the user to access anything in that dir. but at the same time from the same session I want to be able to access files in a mirror site using the same username and password and not having him to enter it again. the username/pass combo is replicated on both the servers, it this possible?
    currently i use the http password protection provided by apache to access one node, but can i use the same session on another machine with the same credentials?
    If this is not possible how can i do this programatically using java? can i do can "ls" on the directory i want on another server and display the list to the user and then when he clicks on that file name i fetch it from the backup/mirror server and have him save it using http or ftp?
    It would be great if we can get a solution to this.
    Thank you very much in advance.
    Ankur

    If you install the web server on different machines, It is possible to share the informations between them.

  • Accessing BAPI's using JAVA with out using webdynpro URGENT

    hi Experts,
    What is the procedure for calling RFC/BAPI's using JAVA with out using the webdynpro. Please let me know what are the possibilities with step by step implementation.
    Regards
    Vijay

    Hi Boris Rubarth,
    Thaks for relavant information.
    I have kind of the requirement. The clinet is asking for connecting the SAP RFC using java application. The build Jar or .war or .Ear for which are going to develop should be compatible for running on any of the Applications server like they have Tom cat, weblogic, websphere server.
    so the .jar for or .ear file which we are going to develop should be able to run accessing the RFC/ BAPIs from any of these servers other than SAP WAS that is what their target.
    Please give me your suggestion, which is better approach. currently their SAP system is 4.6c . So presently it is not possible the webservice approach. But they have plans to go for upgrade to ECC6.0
    In that case only JCO option is possible. If use this option . Is it possible to access application which is deployed irrespective of the WAS by doing the required configuration.
    Basically i am aware of the ABAP webservice work bech steps and also the JAVA coding also.
    Please suggest me what is the better way to achieve this.
    Regards
