Loading classes through RMI

I have a client server app with some classes stored on the server.
DefaultModule extends JPanel {
ItemModule extends DefaultModule {
The server app has both DefaultModule and ItemModule in it's classpath, but the client has only DefaultModule in it's classpath.
If the client requests a DefaultModule from the server, and it sends an ItemModule, can the client read this as DefaultModule and perform method calls as defined in DefaultModule, or will I get a ClassNotFoundException?
I'm trying to install modules onto a server and have the clients load them automatically. I do not want to have to install ItemModule on all clients (which could be 100s).

The files on the server can be put on a webserver.
While starting the server, pass in the remote codebase
java -Djava.rmi.server.codebase=http://myserver:8080 Server
While running the client, it would try to load the classes from the classpath, if not it would dynamically download from the server codebase.
This would work for rmi and rmi-iiop based distributed apps.

  • Mysterious NullPointerException when loading class by RMI

    Hi,
    I have a distributed application where an RMI server puts tasks in a queue and clients connect to the server to obtain tasks to process. My problem is the following. When I install the task code on the clients, and just use RMI to obtain tasks from the server (i.e. no dynamic code loading is being done), everything works fine. However, this approach is not efficient since every time the task definition changes, I'll have to reinstall code on the clients. Therefore, I use RMI to load the task class dynamically and instantiate it on the client (note: a task does not implement Remote, nor is it serializable, for reasons that I'll explain below. Instead I obtain the task class from the RMI server and instantiate it on the client). When I take this approach, I get a NullPointerException inside the task code, that does not occur when I install exactly the same code manually on the clients. The exception always occurs at the same point in the code, but not at the same moment (e.g., sometimes a client processes 100 tasks before it happens, another time 5000, etc.). Moreover, when this happens, all client processes running on the same physical machine (but different JVMs) stop processing, but without throwing any error.
    My question is if anyone has seen this kind of problem before. I know the above description is rather vague, but the specifics are a bit of a long story. Here they come:
    RMI server code snippet:
    public interface ConcurrentEvaluationManager extends Remote {
    //An Individual is serializable and constitutes the data needed for the task
    Individual pollNextToEvaluate(long timeout, TimeUnit unit) throws RemoteException;
    //A FitnessFunction is not Remote nor serializable and constitutes the task algorithm
    //(Performance evaluation of Individual, involving some heavy physics simulations)
    Class<? extends FitnessFunction> getFitnessFunctionDef() throws RemoteException;
    }Code for the class that loads the FitnessFunction code dynamically:
    public class RemoteEvaluatorLoader {
    public static void main(String args[]) {
    //Obtain evaluation manager from RMI registry
    ConcurrentEvaluationManager evalMgr = getRemoteManager(hostName, rmiServerName, port);
    //Obtain fitness function definition and instantiate it
    Class<? extends FitnessFunction> fitnessClass = evalMgr .getFitnessFunctionDef();
    FitnessFunction evalFunction = fitnessClass.newInstance();
    //Start getting Individuals from the manager and evaluate them using the fitness function until the
    //manager says there will be no more Individuals to evaluate
    Evaluator eval = new Evaluator(evalFunction, evalMgr);
    eval.run();
    }Specifically, a task consists of evaluating the performance of a robotic controller using some heavy physics simulations. A task is therefore made up of two things: the encoding of the controller (an Individual, basically a list of numbers), and the performance measure/simulation (the FitnessFunction). The latter is subject to frequent change, so I want to load this code dynamically on the clients using RMI. I can't pass an instance (either serialized copy or remote reference) of the simulation to the client, since it involves communication with a native DLL.
    Stack trace of the error:

            at jbeagle.concurrent.RemoteEvaluatorLoader.main(RemoteEvaluatorLoader.java:33)The line where the error happens is where the insect robot tries to move its legs. One of the legs is null. Again, this doesn't happen when I run the application without loading the code dynamically and install the code for the InsectFitnessFunction, Experiment etc. on the client manually. In the current scenario, all code (InsectFitnessFunction, Experiment, Insect, and other necessary classes) is loaded dynamically and instantiated locally on the client (of course, the necessary native library and the JNI wrapper for it are installed manually on the clients).
    Has anyone encountered something like this before? Might there be a problem with the way I am dynamically loading and instantiating the class? At first I thought it might be due to some problem with distributed garbage collection, but I don't see how since the relevant classes are instantiated locally, even though they are loaded from a remote codebase.
    An alternative version of the error is one where my JVM crashes (error log below). I believe this is basically the same problem, except when the JVM crashes the null pointer happens in the native library.

    Never mind. I have now managed to reproduce this condition without RMI, so it seems to be due to something else after all. Marking this thread as answered.

    Hi Manish,
    It seems that you are using a custom security provider and the weblogic server is not able to find the class / jar file that contains the class.
    java.lang.ClassNotFoundException: Failed to load class com.msl.security.providers.SessionPrincipal]
    Make sure you have all the required jar files in the server classpath.
    You can use the JarScan utility to find the jar that contains the class.
    Refer the below link regarding the jarScan.

  • Passing interface through rmi

    Hi,
    I would like to know if its possible to pass an interface through RMI. I have currently 2 applications connected through RMI. In application A, we have the full running simulation, so is it possible to pass the whole running simulation over to application B through RMI such that whatever is happening on application A would be shown on application B dynamically.
    If rmi cannot do this, what other alternatives do I have. Thanks in advance!

    Yes, you can do this.
    You would not be passing an interface however, you would be passing object A. So make sure A is serialisable, as well as all the objects it is using.
    The receiving VM will need the class files for the objects being used by A, so you have two options:
    The classes can be in the static classpath of VM B.
    The classes can by dynamically loaded from a file server, as needed.
    The first option is simplest, the second is the most flexible.
    One more thing; when you send the simulation A to VM B, you have performed an object 'pass-by-value' which normally does not happen in Java. Therefore, A will be running in VM B, but you will also have your original version, still running in VM A.
    I hope that made sense, for additional insight, you may want to take a look here:

  • Get all th loaded classes

    Dear ppl,
    I have been trying so hard to get a solution to the following problem:
    I needed to know the name of the classes currently loaded in the jvm in a dynamic fashion ie any time I should be able to query jvm and get the list of currently loaded classes (which should not show the unloaded classes). I wanted to keep it simple so I avoided using jpda api. I found an article in java world which says:
    If you really insist on monitoring classes loaded by absolutely every possible classloader in the JVM, it is hard to do so in pure Java.
    You might try forcing every classloader instance to register itself in some global data structure. For example, if you modify both java.lang.ClassLoader constructors:
        protected ClassLoader() {
        SecurityManager security = System.getSecurityManager();
            if (security != null) {
                security.checkCreateClassLoader();
        this.parent = getSystemClassLoader();
        initialized = true;
        ClassLoaderRegistry.register (this);
        protected ClassLoader(ClassLoader parent) {
        ClassLoaderRegistry.register (this);
    to call into the following class:
    public abstract class ClassLoaderRegistry
        public static void register (final ClassLoader loader)
            if (loader != null)
                synchronized (CLASSLOADER_SET)
                    CLASSLOADER_SET.put (loader, null);
        public static ClassLoader [] getClassLoaders ()
            final List /* ClassLoader */ resultList = new LinkedList ();
            synchronized (CLASSLOADER_SET)
                // We are using a weak map: be careful when traversing the key set
                // [it's unsafe to use resultList.addAll(CLASSLOADER_SET.keySet())]
                for (Iterator keys = CLASSLOADER_SET.keySet ().iterator (); keys.hasNext (); )
                    // Note that WeakHashMap guarantees that the weak key will not be
                    // cleared between hasNext() and next():
                    resultList.add (keys.next ());
            final ClassLoader [] result = new ClassLoader [resultList.size ()];
            resultList.toArray (result);
            return result;
        // This field is used as a 'weak set' to avoid interfering with class
        // and classloader unloading and garbage collection:
        private static final WeakHashMap /* ClassLoader->null */ CLASSLOADER_SET
            = new WeakHashMap ();
    } // End of class
    you will in fact track every classloader instance created in the JVM. This happens because every classloader constructor eventually chains all the way down to one of the above two constructors. Then you can use ClassLoaderRegistry.getClassLoaders() followed by the usual ClassScope.getLoadedClasses() to get a full class listing snapshot.
    Of course, you need to deploy both the modified java.lang.ClassLoader and ClassLoaderRegistry in the JVM's bootstrap classpath (using the -Xbootclasspath/p: JVM option) to make this work. This approach is probably only for dedicated Java hackers.
    Now I did exactly what they said. But I get compile time error with the modified ClassLoader.
    So now is there any other workaround? Can you please help me out?

    hi,
    Let me explain u in detail.
    I have a JTextPane through which i load an image.Here is a code snippet
    HTMLEditorKit kit = new HTMLEditorKit();
    JTextPane jtp1=new JTextPane();
    jtp1.setEditorKit(kit);
    jtp1.setEditable(false);
    jtp1.setSize(100,100);
    jtp1.setText("<img src="top1.gif">");
    I add this JTextPane jtp1 to a panel.There are two JTextPane holding different images which are added to apanel in turn.
    When i add these(jtp1,jtp2) to a panel ,then i sometimes see the blank panel.jtp1 and jtp2 does not appear on that.
    So what should i do so that only when all the components are loaded (here jtp1 and jtp2) then only my panel holding jtp1 and jtp2 is displayed.
    Thank you

  • ITunes 10.5.3, Unable to Load Class Data from Sync Services, Crashes Repeatedly

    Ever since iTunes 10.5.3 on my Windows 7 x64 box, I've been having serious problems keeping iTunes running:
    1)  Any time I connect my iPhone or iPad, or any time they attempt to sync over WiFi, I get the 'Unable to load class data from sync services' error.  It's worth mention that the iPhone or iPad do actually then proceed to sync correctly, and all media / data is synchronized successfully, as far as I've been able to tell.  I've reset sync history, restored the iPhone and iPad, manually moved the SyncServices directory, set both the iPhone and iPad up as new, completely uninstalled iTunes and the mobile device software, re-installed, and *nothing* I do fixes this issue or even seems to impact it.  Uninstalling iTunes 10.5.3 and reinstalling iTunes 10.5.2 resolves this error.
    2)  iTunes 10.5.3 has serious crashing problems on my machine, though I've searched through forums and found a lot of other people with the problem.  In my case, sporadically as iTunes access the iTunes store (for example, I can always make it happen by subscribing to the Diggnation podcast and telling it to refresh the podcast), I get a full application crash which generates the following event in the event log:
    Faulting application name: iTunes.exe, version: 10.5.3.3, time stamp: 0x4f14cc3d
    Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
    Exception code: 0x80000003
    Fault offset: 0x0001280c
    Faulting process id: 0x564
    Faulting application start time: 0x01cce78789dc009a
    Faulting application path: D:\Program Files (x86)\iTunes\iTunes.exe
    Faulting module path: C:\Windows\syswow64\KERNELBASE.dll
    Report Id: ecc77400-537a-11e1-b809-00248c196007
    Again, uninstalling iTunes 10.5.3 and re-installing iTunes 10.5.2 fixes this issue as well, but I really shouldn't have to do that.  Is there any actual solution to these problems other than dowgrading to an older version?
    Yes, I'm running current malware protection (and my system is clean) and yes, I've already checked any other obvious culprits to make sure I don't just have a corrupt library or file somewhere that's causing it.  My Windows 7 install is completely up to date from a Windows Update perspective and also from a driver perspective (even including the motherboard and chipset drivers).  I made sure to do a system file integrity check (sfc /scannow) and it confirmed my install of Windows isn't suspect, but beyond all that I was able to reproduce these failures on a completely separate machine running Windows 7 x64, without any of my media library or data on it -- iTunes 10.5.3 just seems to be bad news on Windows 7 x64 for me, even though I know there are definitely people are using it successfully.  I don't get any other application crashes for any other applications, and I've never had an issue like this with any previous version of iTunes...
    Last but not least, in case it matters, I'm running iOS 5.0.1 on both the iPhone4 and the iPad2.  The iPhone4 is the GSM AT&T model and the iPad2 is the CDMA Verizon model.

    OK, I've given up.  Uninstalled iTunes 10.5.3 permanently.  It's a shame, 10.5.2 works perfectly but 10.5.3 is a complete and total cluster for me.
    Anyone with the same problems who hasn't done this already, just uninstall iTunes and the Apple Mobile Device Service in your Add/Remove Programs, then re-install iTunes 10.5.2.  You won't lose your library or any settings or apps, it will just go back to working again.
    I wish Apple would acknowledge this so that I'd at least know it would be fixed in the future.

  • "iTunes was unable to load class data information from sync services"

    I own iTunes 10.5 beta 3 64-bit for my 64-bit windows 7 pc, and it gives me this message whenever I try to sync ANY of my devices: "iTunes was unable to load class data information from Sync Services". I own an old iPod video and an iPhone 4 with iOS 5 beta 3. I've tried uninstalling all Apple products, searching through my hard drive and deleting everything Apple, cleaning the registry, EVERYTHING. I've reinstalled at least 4 times now. The problem refuses to become fixed. I've searched every article online possible, and none of the solutions have worked. Is there anything I can do to get my stuff back on to my devices???

    In the course of your troubleshooting to date, have you worked through the following document?

  • Error in adding attachment to the workitem. load:class Query.class not foun

    Hi,
    We are using WebGui to access the Business Workplace(SBWP transaction) through Portal. For any work item, when i try to import a file from the local PC, i get a screen with the header -"Enter Some FIle attributes". Text displayed in the screen is "Please wait. You will be forwarded automatically. This page had to be included for techincal reasons". And i am struck in that screen. I believe a java popup winddow should come up at this point to select the PC File but it never happened. The screen also has a status message "
    Loading Java applet failed. Applet Query.class not inited ".
    WHen i look at the java console, i find the following error trace. Please let me know if anybody experienced this problem before and how to fix it. Thanks for the help.

    Hi all,
    I have encountered same problem in ITS 6.20.
    Query.class is packed in ws.jar which is stored at C:\Inetpub\wwwroot\<SID>\sap\its\mimes\webgui\99\applets and C:\Inetpub\wwwroot\<SID>\sap\its\mimes\webgui\2002\applets in ITS server.
    I increased the trace level to 3 in the Java console to inevestigate the problem further.
    == Java console (Trace level 3 ) ===
    network: cache entry not found URL: https://hostname.domain.co.jp:443/sap/its/mimes/webgui/2002/applets/ws.jar、version: null
    network: Connect to https://hostname.domain.co.jp:443/sap/its/mimes/webgui/2002/applets/ws.jar (Proxy=DIRECT)
    network: Connect to http://hostname.domain.co.jp:443/  (Proxy=DIRECT)
    java.net.ConnectException: Connection refused: connect
    load: class Query.class not found.
    java.lang.ClassNotFoundException: Query.class
    ==========================
    Then I found out that when system tried to load class Qery.class the connection to ITS was refused becase the incorrect protocol ( https ) was chosen.  In my case, SSL was not setup, therefore protocol must be http.
    I activated http by changing the configuration file for WGate in C:\Program Files\SAP\ITS\6.20\config\ ItsRegistryWGATE.xml
    After that, I restarted the WGate by accessing to http://hoostname.domain.co.jp:port/scripts/wgate/wgate-restart to activate the configuration.
    And also I restarted the AGate by restarting the Windows Service "SAP ITS Manager - <SID>".
    Anyway, the html (BHTML) file that displays the message below is stored at C:\Program Files\SAP\ITS\620\templates\system\dm\itsdoc.html
    "Please Wait. You will be forwarded automatically"
    "This page has been loaded due to technical Reasons"

  • Error loading class problem with applet (Newbie)

    Hi,
    I am new to Java applets. I try to display a simple sample. I put this into html file: <APPLET codebase="classes" code="NewApplet.class" width=350 height=200></APPLET>
    And it always appears one problem:
    Error loading class: NewApplet
    java.lang.NoClassDefFoundError
    java.lang.ClassNotFoundException: NewApplet
         at com/ms/vm/loader/URLClassLoader.loadClass
         at com/ms/vm/loader/URLClassLoader.loadClass

         at com/ms/applet/AppletPanel.processSentEvent
         at com/ms/applet/AppletPanel.run
         at java/lang/Thread.run
    Can anybody help please? Thanks in advance.

    Now I am able to load the applet on MAC OS X 10.4.11. This is due to network issue.
    Now my problem with the applet functionality. My applet will display the map image. Applet contains the navigation arrow keys at the top left of my applet. These keys will be used to navigate through the map.
    The problem is while user using the navigation buttons, the image got squash and stretch.
    This is happened only on MAC OS X 10.4.11 and Its working fine on PC and MAC OS X 10.5.5.
    Please anyone help in this regard. Thanks in advance.

  • Failover to loading classes from codebase?

    The Java Plug-In fails over to loading class files from codebase when the jars specified do not contain the class in question.
    I need this same behavior from Java Web Start -- in part because I'd like to convert some applets and in part because due to customization, reflection, etc, it is not possible for me to force all class files to reside in the jars. Some will only be found in the codebase.
    Is there any way to accomplish this with Java Web Start? Or do we have to use another JNLP implementation? I understand performance is best when the jars are complete, but why did Sun make Java Web Start's behavior so inconsistent. [This is not the only case of this, but I'll keep my other questions/gripes on this matter to other threads.]

    I fully agree with your opinions on the environment variables such as CLASSPATH, PATH etc.
    But my problem is: I want to force the application to load the classes over RMI from the codebase specified by the other machine first before trying to load the classes from its own class path specified by -cp or whatever mechanisms.
    In other words, I want to load the classes remotely instead of locally on the hard drive if the classes with the same names exist locally.

    Hi Manish,
    It seems that you are using a custom security provider and the weblogic server is not able to find the class / jar file that contains the class.
    java.lang.ClassNotFoundException: Failed to load class com.msl.security.providers.SessionPrincipal]
    Make sure you have all the required jar files in the server classpath.
    You can use the JarScan utility to find the jar that contains the class.
    Refer the below link regarding the jarScan.

  • Load class in Oracle

    Hello!
    I wrote the java class that uses classes from jar files that are not in Oracle. Jar files I added to the environment variable CLASSPATH. When I load my class through the program loadjava you get an error ORA-29521 referenced name (the class from the jar file) could not be found. How do I fix this problem? Oracle 10.2.0.4

    Hi,
    I think you are not pointing to the jvm inside the database, please look at the 10g2 documentation
    http://download.oracle.com/docs/cd/B19306_01/java.102/b14187/chone.htm#BABCFDJH
    it states:
    "In this release, the system classes are upgraded from J2SE 1.4.1 to J2SE 1.4.2"
    So if you use generics you have to remove then or try to to use
    If you want to keep the code with generics you can try retrotranslator and see if it works with the Oracle jvm (I didn't try)
    ciao,
    Giovanni
