RMIClassloader same class name different versions

I am writting a system so that I can have a task server send tasks off to a computing node and return the results. The plan is to set these clients up on a bunch of unused pcs around my university. Something that I am starting to wonder about though is if I run a distributed application once, then change parts of that application, will the RMIClassloader on the client know to redownload the applicable jar or will it try to use the old jar file which (I assume) it has cached or loaded already? The reason is, is that I I am in a development stage and my codebase might be changing although once the client and server are built I don't plan on making many changes to it after it is degugged.
Thanks,
RDL

The same JVM will use the same downloaded class, but a new JVM will do a new download. There is no caching between JVM invocations. You do need to consider the effect of local HTTP proxy caches as well if there are any in the network.

  • Same class name, different packages

    Let's say I have two classes called Team, and each are in their own package. I go to import a.Team and b.Team, what do I have to do to make this work?

    Import them both if you need them both. When you go to use them, refer to them by their fully qualified name.a.Team aTeam = new a.Team();
    bTeam bTeam = new b.Team();You don't really need the import statements from a programatic point of view, but it helps make your code more legible to other developers.

  • Firefox Sync on same computer with different versions of Firefox

    Hi,
    I know how to use Sync on two different computers and a mobile device, but how can I Sync two or more different versions of Firefox (Nightly, Beta, Aurora, Release Candidate)? I can't get the code from the other computer/firefox because I can only have one version of Firefox open at the same time. I tried it. This is my setup. I have a different Profile for each version of Firefox I have. I also have each version of Firefox installed in a different directory, for example:
    Nightly - C:\Program Files\Mozilla Firefox\Nightly\
    Aurora - C:\Program Files\Mozilla Firefox\Aurora\
    Beta - C:\Program Files\Mozilla Firefox\Beta\
    Release Candidate - C:\Program Files\Mozilla Firefox\Release Candidate\
    and my Profiles are in my
    Nightly - C:\Users\David\AppData\Roaming\Mozilla\Firefox\Profiles\David-Nightly\
    Aurora - C:\Users\David\AppData\Roaming\Mozilla\Firefox\Profiles\David-Aurora\
    Beta - C:\Users\David\AppData\Roaming\Mozilla\Firefox\Profiles\David-Beta\
    Release Candidate - C:\Users\David\AppData\Roaming\Mozilla\Firefox\Profiles\David-Release Candidate\
    and I run Firefox with the following command (Properties/Target)
    "C:\Program Files\Mozilla Firefox\Nightly\firefox.exe" -P "David-Nightly"
    "C:\Program Files\Mozilla Firefox\Nightly\firefox.exe" -P "David-Aurora"
    "C:\Program Files\Mozilla Firefox\Nightly\firefox.exe" -P "David-Beta"
    "C:\Program Files\Mozilla Firefox\Nightly\firefox.exe" -P "David-Release Candidate"
    Can anyone help me so that I can Sync all the accounts (basically, just the bookmarks), so I will have access to all my bookmarks, instead of going to the firefox version I saved it in? I would appreciate any and all assistance concerning this matter.
    Thank You.

    Use the -no-remote command line switch to open another Firefox instance with its own profile and to run different Firefox instances simultaneously, but do not use -no-remote with the default browser and the default profile.

    Enter all details like the account name (email address) and password and the 26-character Sync key manually to connect to an existing sync account instead of using the 12-character code to pair a device if pairing isn't possible.
    # open "Tools > Options > Sync" or "Firefox > Set Up Sync"
    # click "Set Up Firefox Sync" to go to "Firefox Sync Setup"

  • Different plan for same SQL in different version of DB

    Hello,
    At client side i have upgraded database from 11.2.0.1.0 to 11.2.0.2.0 . and after that i am facing performance related issue.
    is this happen because of up-gradation ?
    for testing i have created two different version db (i.e 11.2.0.1.0 to 11.2.0.2.0 ) with same volume and same parameter. now i am executing same query then i am getting different plan.
    please help me to resolve this issue..

    Which issue? CBO is upgraded with every new release! So, yes, execution plans may change because of that.
    And sensible DBA's first upgrade a test database.
    Also no statement is to be seen.
    Secondly, you can always set optimizer_features_enable to the lower release.
    Finally, please look up 'upgradation' in an English dictionary. You won't find it!!!

  • Can we have two clusters in same domain running different versions of WLS

    I have not tested this yet but was looking for help from people who might have done this already.. Is it possible to have this scenario:
              create two independent clusters, say C1 and C2 as part of a single domain D. C1 has 2 managed servers running WLS8.1 and C2 has 2 managed servers running WLS7.0
              Can this be done?
              Thanks,
              Raghu

    It is definetely inviting for trouble.
              We can have two clusters from same version of weblogic server within a domain.
              If we have a WLS8.1 domain, the managed servers that we create from that domain should be from WLS8.1.
              As far I remember, its not a supported configuration to have different versions(major versions) of Admin and managed servers.

  • Same circuit design-different versions of multisim now fixed

    remade circuit model 74LS244N, now pattern16t file works in different versions of multisim.
    how much do you think pattern16t cicuit could be worth.
    this circuit interfaces with gpib, scsi, usb computer interface circuits.
    this is just the hardware. software still would have to be made for each computer.
    basicly there are the computers with a different interface.

    Hi there,
    The application sounds interesting for interfacing instruments or devices with these buses. Of course, you have to take into consideration that there are off-the-shelf products that come with drivers, etc.
    By the way, I really liked how you organized the schematic in Multisim with buses, etc.

  • Same class in different package

    I am facing a design decision, I have a set of classes which defined the values of all variables. However, I realized that I need to prepare
    separate set of these classes for different countries (as they may vary), i.e
    my.package.us
         PriceList.java
    my.package.ca
         PriceList.java
    PriceList.java
    ===============
    Public class PriceList {
    public final static Price directFlightPrice = new Price(13500,2); // where 0 is the decimal places
    public final static Price connectFlightPrice = new Price(11000,2); // where 0 is the decimal places
    I am not sure how I can achieve this, would you guys please help? Thank you!

    Isn't this more what you need? You don't want to create a new class, you should create a new instance of a class.
    class PriceList {
        private Price directFlightPrice;
        private Price connectFlightPrice;
        private String country;
        public PriceList(String country, Price directPrice, Price connectPrice) {
            this.country = country;
            directFlightPrice = directPrice;
            connectFlightPrice = connectPrice;
        ... methods to use pricelist variables
    class PriceListTest {
        public static void main(String[] args) {
            Map<String, PriceList> pricesPerCountry = new HashMap<String, PriceList>();
            // This is where you could load data from file and put it into a PriceList object...
            PriceList plUK = new PriceList("UK", new Price(...), new Price(...));
            PriceList plAu = new PriceList("Australia", new Price(...), new Price(...));
            pricesPerCountry.put(plUK.getCountry(), plUK);

  • Same file name - Different extension - Viewing problem

    I know this has been written about quite a bit and I have searched through the posts but I cannot find a solution to my problem. I shoot RAW, import then into Lightroom, make changes, import into CS3 & make more changes, save as a .psd file; no problem so far. I use Neat Image on some files that need the noise reduction so in CS3 I save the .psd as a .tif, run it through Neat Image and save it to the same directory where the RAW and .psd files are. Go back to Lightroom and no .tif file. If you "find" the file in Lightroom it shows up but shows as the .psd file. I have tried unstacking and everything else I can think of but I cannot make the .tif file display. I can go back to CS3 and locate the file through it but if in a few months or however long it takes me to forget that the .tif is there, the .tif will be lost in never never land. Bottom line, how do I get Lightroom to show ALL files, no matter name, extension, etc?
    I am using Version 1.3.1 on Windows XP, 2Gigs ram, 3.4 Gig P4 processor

    This issue was argued down to skeletal remains in beta and after. Adobe finally rlented somewhat and allowed the importation of files with same name and the RAW and jpeg extensions, because for one good reason some cameras produce both and some shooters utilize both for differring purposes.
    Jao,
    I will disagree with your reading of what is standard. That MS's stupid explorer or anything else won't show extensions is immaterial. First, anyone wanting to work at any speed and efficiency will be using something like Total Commander instead of Explorer, and it and virtually every other app I own shows extensions and treats files with the same name but differing extensions as unique files unto themselves--as it should be.
    After all it is digital data in the file that is unique. The extension is a tag to tell you and the computor how to deal with that data. The content is not identical, and therefore it ought not be treated as if it were by any application.
    Anyone with an interest in wasting several hours can trace the arduous wailing at the LR team to treat the extension as part of a unique name. As I said bdefore, they did make some concessions. Hopefully, they will go the whole distance soon.

  • 2 Jars with same class name. NoSuchMethod. Can't change classpath

    I have overloaded a method in a class that came with an openSource package.
    Things were fine until I implemented my components in a new version of the Server application; when I discovered that the it uses the same openSource package bundled in its classpath.
    This results into a NoSuchMethod exception since I have overloaded the method with new argument types.
    1. I cannot remove or shuffle this JAR from the Server's classpath, since that would stop something else.
    2. I cannot change my code since it is implemented in a lot of places.
    Has anyone called a specific method of a jar? like E.g. "someJar.jar".SomeClass.someMethod (arg);
    If yes how?
    The above code is not possible syntactically, but I have put it for ease in interpreting the problem.
    Any input will be appreciated.
    NOTE: I cannot disclose the names of products for company policy issues.

    Just some ideas...
    1. I cannot remove or shuffle this JAR from the
    Server's classpath, since that would stop something
    else.Some servers allow for multiple classpaths - i.e. you can separately specify the classpath that the server itself uses from the one that your hosted applications will be using.
    Also, if your changes to the openSource code are only the addition of an overloaded method, why couldn't you just substitute your jar for the one the server is using, why would that break the server?
    2. I cannot change my code since it is implemented in
    a lot of places.That sounds lame. You can't do a global replace? How about just changing the package name?
    Has anyone called a specific method of a jar? like
    E.g. "someJar.jar".SomeClass.someMethod (arg);
    If yes how?Yes, but it's not as simple as your pseudo-code...
    You can use URLClassLoader to load a specific class from a specific jar file URL, and then use reflection to get the method you want from it, and then call it.
    good luck

  • Cant' create preset to scan to PDF using same scanner but different version of Acrobat

    Hello,
    We upgraded 3 out of 4 workstation to Acrobat Pro XI and since then we've been unable to use the Create PDF from scanner.
    The scanner hasn't changed (Dell MFP) and the driver hasn't changed either. Our colleague who's still using v9.2 PRO is able to create PDF from scanner (using B&W preset) with no issues.
    We on the other hand are no longer able to create PDF from scanner - it throws an error message saying the scanner model does not support presets: it DOES! (since the other user can do it).
    The only difference is that we've upgraded.
    The only way we can get the scanner to work is through a Custom scan and then a helper app pops-up to do scan or preview which never happened before.
    Can you please help? this is very frustrating. Should we cancel our subscription and go back to v9?
    Thanks!
    Best,

    Hi msfdr,
    I assume you are facing problem on windows machines.
    You may try following steps.
    1. Click on Start button > search > run.
    2. Launch Run.
    3. type %appdata%, hit on ok.
    4. You will get browsed to C:\Users\(xxxxx)user name\AppData\Roaming
    5. Go to Adobe folder > Acrobat.
    6. If it is Acrobat 11.0, there should be 11.0 folder. Rename the folder as Old_11.0.
    7. Launch Acrobat again and try.

  • How to load the same classes of the same name, from different jars

    Hi,
    I have several different versions of my project in respective jars. I am trying to develop a configuration app, which will have the most current version of my app packaged within it. Then the user will make a selection, and if that selection is an older version, a specific class from one of the jars...which will continue to load other classes within that same jar. If it is the current version, the class will be found within the codebase.
    My question is if this is even possible? Can I load a class from a jar file which has the same file name and package as what is in my current code?

    nasch_,
    So I have been searchin around, and found some good tutorials on classloaders, But i still see a problem.
    Whether I use the same classloader for different sources or not, the problem lies within the reference to the class i am loading. Since this class (a different version of it), is also in the classpath, how does the code know which class is being returned?
    I am having trouble putting this into words, but basically. i don't see how my application will know that i am returning an instance of a class which is not in my classpath.

  • Class name and package name clashing

    When i have a class and a package with the same name, I cannot access classes in the package. For example I have 3 classes and 1 package as below
    - Test.java
    - PackageName.java
    + PackageName // this is a directory
    - MyClass.java
    Below are the codes of .java files
    Test.java
    =======
    public class Test { PackageName.MyClass a = new PackageName.MyClass ();}
    PackageName.java
    ===============
    public class PackageName{ }
    MyClass.java
    ==========
    package PackageName; public class MyClass { }
    I can compile PackageName.java and MyClass.java but not Test.java. It says
    cannot resolve symbol
    symbol : class MyClass
    location: class PackageName
    PackageName.MyClass a = new PackageName.MyClass ();
    But if I remove the PackageName.java, I can compile Test.java perfectly. I think when I use PackageName.MyClass, java thinks that I try to access an inner class MyClass of PackageName class, and that does not exists. Is there any way to solve this ambiguation, other than making the package name and class name different? Thank you very much.

    This works fine: just add an import to Test.java.
    import PackageName.MyClass;
    public class Test
        public static void main(String [] args)
            MyClass a = new MyClass();
    public class PackageName {}
    package PackageName;
    public class MyClass {}It's a pretty wacky, useless example, but it works.
    Plus I thought inner classes would have a dollar sign in their .class file names. When I compile this:
    public class OuterClass
        public static void main(String [] args)
            OuterClass outer = new OuterClass();
            System.out.println(outer);
        public String toString() { return "I'm an OuterClass"; }
        class InnerClass
            public String toString() { return "I'm an InnerClass"; }
    }I see two .class files: OuterClass.class and OuterClass$InnerClass.class
    Why make up examples like this? It's hard enough writing code, and it's easy to disambiguate for the compiler.

  • Using same class for duplicate movieclips

    Hello everyone,
    I have created an external class for a particular movieclip and I would like to link a duplicated version of this movieclip to the same class file.
    Problem is I can't seem to do it. Even if I state the class as the BASE class of the new movieclip and create another random class name for it.
    Is there a way I can get around this so I can assign my duplicated clip the same class name ??
    Thanks in advance

  • How can OIM provision users with same Display Name in AD?

    I can create users with same First Name, Middle Name and Last Name (same Display Name) in OIM if they have different UserId.
    But I can not provision two users with same Display Name to one Organization Unit in AD, the resource provisioning shows
    Status: Rejected
    Response: AD user already exists
    Can AD be configured to create users with same Display Name (different UserId) in one OU, or would I have to create logic in OIM to modify the display name so it gets accepted by AD?
    Thanks!

    Thanks Nitesh. Also, I can create the user with same DN in different OU's, not in same OU.
    I agree once we determine that same cn exists in one OU , I can modify the display name by appending a number at the end or something. I understand the logic but I need more details on how to specify this logic in the pre-pop adapter, can you please share more details.
    Thanks a lot!

  • How can i deploy two different versions of the same application on the same server??

    I have two different versions of an application. One is a released version. And another version under development. I need to port this version of the application to the same server. I'm using the same classes and packages(except for some new ones). Is it sufficient if i change the name of my ear(application name). Or should i change my code also.

    Hi
    You can repackage the new versions of ear,jar and war with different names. I hope that should work well.
