Problems loading classes rutime.

HI.
Imagine you have a program which calls some method from a class. I'd like to let the user load this class while the program is running, just like a plug-in. How can I do it?
thank you in advance.

ClassNotFoundException trying to load classes in a .war file inside an .ear file

Hi. I've deployed an EJB2 enterprise app as an ear file on WebLogic 6
          without errors. The ear file contains web app and ejb components in war and
          jar files. The web component is set to be the default web app in the
          config.xml file. Everything deploys without error messages.
          My problem is that I get ClassNotFoundExceptions when I try to invoke a
          servlet (via its servlet-mapping) or do Class.forName() on any class file in
          the war file.
          I see in '.wl_temp_do_not_delete' that the ear file has been decomposed into
          the ejb jar and web war files. The war file is not 'exploded' into a
          directory structure, however (as the console.war is). Is this an error
          (should the class packages in the war file be 'exploded'?)
          I don't see a tag in the web.xml, config.xml, or application.xml that tells
          the server to explode the war file--is there one?
          Note that if I manually copy the exploded class folders into the
          '_tmp_war_myserver_myserver_<<webappname>>' directory (and not, curiously,
          into a WEB-INF/classes subdirectory of that directory), the servlets and
          other classes load correctly. Also, jsps and html files load just fine
          without exploding the war file.
          Note also that the server complains about not being able to find the
          classes, even though it reports that the decomposed war file is in the
          classpath. Is there a problem loading class files from a .war file (because
          the namespace is different, with root classes located in WEB-INF/classes
          rather than the .war file's root?)
          Also, in the application.xml file, what is the meaning of the
          <context-root></context-root> element? What should its value be? What if
          you leave it blank?
          Thanks for any help,
          Reid


Is there a way to add jar libraries to the Oracle JVM CLASSPATH? Is this the same as the system's CLASSPATH env. variable?
Thank you!
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Alex McClennan ([email protected]):
The package prefix in the code extract was correct - i.e. "oracle.aurora.jndi". A value of "oracle.aurora.jndi.*" would be incorrect.
The problem is that the context factory implementation specified (com.evermind.server.ApplicationClientInitialContextFactory
) can't be found, the mostly likely reason being that the library containing the class isn't on the classpath.

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.

Can't load class problems migrating from PE 8.1 to PE 8.2

Hi. I'm in the process of migrating an application from an old server that runs PE 8.1_02 to a new server that runs PE 8.2.
The application is coded and built in Creator 2.0; the resulting .war file deploys alright into both servers, and operates correctly on the 8.1 server, but throws various "Can't load class" errors on my 8.2 server. One of them looks like this:

The class that is "missing" (TextBoxField) is very definitely there in the usual place under WEB-INF/classes. I can't figure out why it can't be loaded. The weird part is that a lot of the code still works, but these errrors have broken many of the major functions of our software.
On a hunch I realized that perhaps Creator 2.0 was using some 8.1 specific libraries to build, so I replaced the following libraries with versions found in my appserv tree:
activation.jar
appserv-jstl.jar
appserv-tags.jar
commons-logging.jar
j2ee.jar
jax-qname.jar
jaxr-api.jar
jaxr-impl.jar
jaxrpc-api.jar
jaxrpc-impl.jar
jsf-api.jar
jsf-impl.jar
mail.jar
saaj-api.jar
saaj-impl.jar
Rebuilding with those copied libraries made no difference.
Anyone know what could be causing this? Is there a workaround or fix? Do I need to update Creator with something? Should I revert to 8.1? Should I try moving to 9.0?

I solve this problem by doing a remote deployment via creator2 remote deployment server.. first you must take care of JNDI stuff..
I hope this help.. give me feedback

WARNING: Problem validating implementation class. Failed to load class:

when i am running plsqlAssembler.jar file for wsa.jar with all other atributes , i am getting this warning WARNING: Problem validating implementation class. Failed to load class.
Please if anybody knows about this reply me,
thanks in advance.

If you are using Ex in the implemetation class, make sure that you also include the same in the interface (or SEI).
If the implementation looks something like:
public void doSomething() throws Ex {
System.out.println("Is there something to do, now ?");
then the SEI should be:
public void doSomething() throws Ex, RemoteException;
If your have ommited Ex, then you will have the warning you are seing, and there wont be any artifact generated for Ex in the WSDL.
Because the Ex exception was not mapped to any WSDL artifact, there is no way you will see the Ex exception generated on the client side (or proxy).
I have been able to reproduce your error message, so you should be all good.
WARNING: Problem validating implementation class. Exception declaration mismatch between Implementation: bugyyy.MyServiceImpl and Interface: bugyyy.MyWebService. Impl class Method: doSomething declares exceptions not declared by the interface (bugyyy.Ex)
Hope this helps,

What types of problems stem from high number of loaded classes?

Currently we are in the process of testing our code for long-ish periods of time, between 4 hours and 24 hours+ non stop. The code is not interactive/user based. I first noticed that our garbage collection times were very high (about 15-25% of our total processing time). I then looked at loaded classes and there is a pretty steady rise over team of loaded classes. At the time of start up it is around 6-7k. After appproximately 4 hours its up around 25k loaded classes. Only 35 or so classes have been unloaded over this time. I'm wondering if the high number of loaded classes occurs because objects aren't fully dereferenced but then when a new object is created it reloads the class. My knowledge of class loading is fairly limited. Any help would be appreciated. Also, if you need more info let me know.
Heap Size: ~2GB

Take a look at this example and the output:
public class Example {
      * @param args
     public static void main(String[] args) {
          StaticBlocks a = new StaticBlocks();
          StaticBlocks b = new StaticBlocks();
          a = new StaticBlocks();
class StaticBlocks {
     static {
          System.out.println("A static init block. Only happens when class is first loaded.");
          System.out.println("\tInstance init block. Happens every time a class is instantiated.");
     StaticBlocks(){
          System.out.println("\tYou instantiated a class!");
}Output:
A static init block. Only happens when class is first loaded.
     Instance init block. Happens every time a class is instantiated.
     You instantiated a class!
     Instance init block. Happens every time a class is instantiated.
     You instantiated a class!
     Instance init block. Happens every time a class is instantiated.
     You instantiated a class!I'm really not sure where to go from here... hopefully someone else that knows the JVM better can provide some insight.
Take a look at this link. It gives some details on class loading... might help you out a little.

Problem with loading classes!!!

I am loading classes using
// Open File
InputStream jarFile = new BufferedInputStream(new FileInputStream(
pluginPath));
// Get Manifest and properties
Attributes attrs = new JarInputStream(jarFile).getManifest().
getMainAttributes();
jarFile.close();
// Read Main Class
String mainClass = attrs.getValue("Protocol-Class");
// Load all classes from jar file without giving classpath
URL url = new URL("jar:file:" + pluginPath + "!/");
JarURLConnection jarConnection = (JarURLConnection) url.openConnection();
URL[] urls = new URL[] {
url};
ClassLoader classLoader = new URLClassLoader(urls);
// Create new instance of protocol
Protocol protocol = (Protocol) classLoader.loadClass(mainClass).
newInstance();
I am loading classes one by one say a order A, B, C. In my case class c extends class A. So I am loading class A first and later B and finally C. But I am getting exceptions when loading class C that Class A is unknown.The following exception is thrown
java.lang.NoClassDefFoundError: com/a/A at java.lang.ClassLoader.defineClass0(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:537)
Please give me a solution to make it run.

You create a new class loader for each class. The class loaders are independent, and so the class hierarchies they load are independent. Class A loader by classLoaderOne doesn't see class B loader by classLoaderTwo - they are loaded into their own sandboxes.
Either load everything with one class loader or create the class loaders in a hierarchy. To create a hierarchy use the class loader constructor that takes a parent class loader as a parameter. One class loader may be easier because then you don't need to worry about loading order.

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

Eclipse Plugin Creation - "Plug-in name was unable to load class " error

Hi everybody and happy new year to you all,
i got a little problem again. I have written the first lines of code of my plugin and wanted to test it (run as Eclipse Application). I got the following error-msg, when clickin either on the menu item or toolbar button:
"Could not create action delegate for id: org.eclipse.tui.inpulse.actions.InpulseStart
Reason:
Plug-in org.eclipse.tui.inpulse was unable to load class org.eclipse.tui.inpulse.InpulseStart."
My project has the following properties (of which i read they are important):
Source folder: org.eclipse.tui.inpulse/src
Output folder: org.eclipse.tui.inpulse/bin
Dependencies: org.eclipse.ui, org.eclipse.core.runtime
Extensions: org.eclipse.ui.actionSets
ExtensionsPoints: none
The following is my plugin xml:
<plugin>
   <requires>
          <import plugin="org.eclipse.core.resources"/>
        <import plugin="org.eclipse.ui"/>
    </requires>
    <runtime>
          <library name="Inpulse.jar"/>
    </runtime>
    <extension
          id="org.eclipse.tui.inpulse.InpulseActionSet"
          name="org.eclipse.tui.inpulse.InpulseActionSet"
          point="org.eclipse.ui.actionSets">
        <actionSet
            id="org.eclipse.tui.inpulse.InpulseActionSet"
            label="Inpulse"
              visible="true"
         description="The action set for the Eclipse Hello World example">
         <menu id="org.eclipse.tui.inpulse.InpulseMenu" label="Inpulse">
               <separator name="samples"/>
         </menu>
         <action id="org.eclipse.tui.inpulse.actions.InpulseStart"
               menubarPath="org.eclipse.tui.inpulse.InpulseMenu/samples"
               toolbarPath="Normal"
               label="Inpulse"
               tooltip="Start pattern search."
               class="org.eclipse.tui.inpulse.InpulseStart"/>
        </actionSet>
   </extension>
</plugin>The javafile "InpulseStart.java" is in the "org.eclipse.tui.inpulse" package and has the first line "package org.eclipse.tui.inpulse;". The class "InpulseStart" implements "IWorkbenchWindowActionDelegate".
So the following members are implemented:
public void run(IAction proxyAction){...};
public void selectionChanged(IAction proxyAction, ISelection selection){...};
public void dispose(){...};
//and some additional ones ;-)I really dont know what i do wrong. If you have an idea, what i just miss out or do wrong, id be glad if you helped me out!
Cya

Aye, you are right, i should/could have posted this somewhere else. I just hoped, that i can get a good answer here, cause ppl helped me out very nice before.
Im sorry if i offended users of this forum...
The "advice" is recognized and i will post somewhere else in case i have a eclipse specific problem.

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.

Load:Class * not found - in portal

In the webgui /portal a link is provided.
when you click the link , which is mapped with the transaction
code of the ABAP program. gets displayed.
THis program is used to download PO into the File
server.
so File output path is given.
The user uses F4 help to select the directory / filename as well
In the bottom we are getting a messge
load: class FileName not found
and load: class Directory Select not found
I use cl_gui_frontend_services=> directory_browse
and kd_get_filename_on_f4.
wat might be the problem for this?
Give me your valuable suggestions
This is urgent.

Hi,
the abap code you use, uses java for getting a filename and for directory browsing. So first of all you have to check,
if java is activated in your browser. Second, you have to test the frontend services in webgui with transaction se37, ws_query, enter "cd" into field query and executer this. Then you will get a security popup, which you have to accept. If all runs ok,
you will get the current home directory as result. If you get a java exception again, you have to check the network configuration
in the java control. It should be the same, as in the browser. If this does not help, try to request the applet ws.jar from the mimerepository .../sap/its/mimes/webgui/2002/applets/ws.jar
directly. Do you get the security dialog? The error you wrote above means, that the java applet ws.jar could not be loaded.
Is this an inhouse problem? external or integrated IITS. Which browser, which java version?
Regards,
Ralf

Load Class in Interface Builder 3

Hello,
i am trying to get started with Cocoa after having worked a while with Xcode & smaller AppleScript based projects.
As my idea was to create a menubar-based (NSStatusItem) service app for myself i started with this tutorial:
http://files.semaja2.net/NSStatusItem%20-%20ObjC.html
Unfortunaly it seems like there was a change in Interface Builder regarding loading Classes from Version 2 to IB version 3
The tutorial tells me to (about the middle of the tutorial):
Rename the “NSMenu1” to “StatusItem”, following this in “Interface Builder” >>choose from the menu “Classes > Read Files..” now select the AppController.h >>file, Once the file has been read it should change out project view to “Classes” >>from here find the AppController item and right click on it and select >>“Instantiate AppController”:
I was able to follow the tutorial until there without problems but it looks like the Classes-Tab is gone in IB 3.x.
So i feel somehow unable to finish this small tutorial.
how would i do this step in Interface Builder 3.x ?
Any help is heavily appreciated.
Best regards

You're right, this has changed. I'm currently using IB 3.1.1 but I believe the changes appeared in IB 3.
Once you've done the "Read class files" and selected your AppController.h file IB should know about your class.
In order to instantiate your AppController in IB first go to the Library window and find the "NSObject" (it will appear as a blue cube). Drag one of these NSObject's from the Library window and drop it into your MainMenu.xib window along with the other icons that appear there (File's Owner, First Responder, Application... etc).
Now you will have created an instance of an NSObject in your MainMenu.xib file. And, since your AppController class is a subclass of NSObject (and IB knows this since you've had it read in your AppController.h file) you can now change this NSObject instance into an instance of your AppController.
Select the NSObject icon in the MainMenu.xib window then go to IB's Inspector window and click on the next to last icon in the top tool bar. This should change the Inspector window's title bar to say "Object Identity" and the Class Identity in the first text field should be set to NSObject. You should be able to type "AppController" into this field (or click the popup and it should show up in the popup list. Once you've done this it will transform the NSObject instance into an AppController instance.
You'll see another slight difference between IB 3.x and the tutorial when you do the <Control>-Drag between items to connect up the outlets and actions. Instead of finalizing the connections in the Inspector window like the tutorial says you'll get a small popup window right next to the item you're connecting to that will list the available outlets/actions you can connect to. Simply click the one you want. You can still double-check your connections in the inspector window though.

"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?
iTunes for Windows: "Unable to load data class" or "Unable to load provider data" sync services alert

Windows Vista "java.lang.ClassNotFoundException: loader.class" error.

Hello,
Whenever I try to visit websites that have a java applet I get a dialogue with the following error:
java.lang.ClassNotFoundException: loader.class.
I have tried uninstalling/reinstalling java, and also adding the -xmx and -xms parameters for java applet runtime setting in control panel with various values from 128m to 1g.
The applet at http://www.java.com/en/download/installed.jsp?detect=jre&try=1 does work and reports "CONGRATULATIONS, you have the Latest version of Java!", "Java Runtime Version 1.6.0."
I have been experiencing this problem ever since I installed Windows Vista Home Premium a day or two ago. Any help is appreciated.
Regards
Greg
