Dynamic class loading issue with XmlBeans and Axis2
Hi,
Since support to web services is not enough in JDeveloper I am using apache axis2 to consume web services from an ADF web application.
Everything works fine if I use jdk 1.5 but our app servers require jdk 1.4.2_08-b03 so I switched jre settings to jdk 1.4.2_08-b03 in the JDeveloper and I started to get these issues.
I debugged the application and this line is the cause of the exception. It is in request document class.
return (org.htng.pws._2008a.guestselfservice.name.types.FetchProfileRequestDocument)org.apache.xmlbeans.XmlBeans.getContextTypeLoader().newInstance(type,
null);
I did some further testing and found that it is happening when I call org.apache.xmlbeans.XmlBeans.getContextTypeLoader()
The error messages that I am getting are
1. J*BO-29000: Unexpected exception caught: java.lang.IllegalAccessError, msg=tried to access field* org.htng.pws._2008a.guestselfservice.name.types.FetchProfileRequestDocument$1.class$org$htng$pws$_2008a$guestselfservice$name$types$FetchProfileRequestDocument from class org.htng.pws._2008a.guestselfservice.name.types.FetchProfileRequestDocument
2. tried to access field org.htng.pws._2008a.guestselfservice.name.types.FetchProfileRequestDocument$1.class$org$htng$pws$_2008a$guestselfservice$name$types$FetchProfileRequestDocument from class org.htng.pws._2008a.guestselfservice.name.types.FetchProfileRequestDocument
As I understand somehow the application server is not allowing the XMLBeans APIs to dynamically load the classes ..But I couldn’t find a way to convince it..
Does anybody have any idea by any chance?
Thanks a lot
Some more details ..
I could make it work if I change the below getClassLoader with Thread.currentThread().getContextClassLoader()
org.apache.xmlbeans.XmlBeans.typeSystemForClassLoader(FetchProfileResponseDocument.class.getClassLoader()This is a generated code and normally works fine with jdk 1.5 .. I guess there should be some setting to make it work in 1.4 as well..
Any Idea ?

Class loading issue with JDK 1.5
I have recently loaded JDK 1.5 on a laptop that previously had version 1.3. The java code I need to run stopped working and I getget a java.lang.NoClassDefFoundError. I am logging the classpath and I see the jar file with the offending class is there.
I checked my pathing even, since I know java will have a problem with slashes at the beginning of the path when it is called via command line. But all my pathing is absolute.
In the code, I am using C to start up the JVM and then use JNI to communicate between java and C. Because of this complexity, I have searched the forums for problems with JNI and JDK 1.5. I found a case where turning off the JIT compilation kept the JVM from crashing for some users having issues with 1.5, but this approach did not work for me. Not too surprising, though, since this is really a classloading issue.
Where do I go next? Anyone else having this problem?[http://java.sun.com/javase/6/docs/technotes/guides/security/SunProviders.html]
Reminder: Cryptographic implementations in the Sun JDK are distributed through several different providers
("Sun", "SunJSSE", "SunJCE", "SunRsaSign")
for both historical reasons and by the types of services provided.
General purpose applications SHOULD NOT request cryptographic services from specific providers. That is:
getInstance("...", "SunJCE"); // not recommended
vs.
getInstance("..."); // recommended
Otherwise, applications are tied to specific providers which may not be available on other Java implementations.
They also might not be able to take advantage of available optimized providers (for example, hardware
accelerators via PKCS11 or native OS implementations such as Microsoft's MSCAPI) that have a
higher preference order than the specific requested provider. -
EP 6.20 Class loader issues with irj application
Hi All,
I have a servlet to interface with the SAP UM API. I had deployed this as a WAR, but the SAP UM cannot be initialised outside of the irj application (SAP Support advised this it is abailable outside the irj application in 6.40).
As a result, I tried to deploy it within the irj application - I copied my jars to the WEB-INF\lib directory, and modified the WEB-INF\web.xml to include a new servlet and servlet-mapping.
I also had to copy some other SAP supporting jars into WEB-INF\lib (the XML parser impls).
This works fine for the UM stuff. Ideally I'd like to redeploy the irj application so I don't have to hack the files and it would allow me to specify the additional libaries required, however there is now way I've found in the Deploy Tool to do this (you need the WAR of the irj application, or the project file). So this is problem 1.
Problem 2. The next extension included support for user mapping data.
Using -
IUserMapping iUserMapping = UMFactory.getUserMapping();
iUserMapping.getUserMappingData(systemAlias, iUser, mapLogonData);
I was able to read the mapping data, but this required knowing beforehand, all the system aliases. With a response from SAP Security, it was suggested
IUserMappingService iums = (IUserMappingService)PortalRuntime.getRuntimeResources().getService(IUserMappingService.KEY);
IUserMappingData mappingData = iums.getMappingData (systemAlias, iUser);
be used to obtain mapping data, and that
com.sap.portal.pcm.system.ISystems sysSrv = (ISystems)PortalRuntime.getRuntimeResources().getService(ISystems.KEY);
String[] systemAliases = sysSrv.getAliases();
be used to obtain the system aliases.
The problem is with the class loader. If I copy the jars with the classes for the IUserMappingService and the ISystems, to the irj WEB-INF\lib I cause a class def not found with other EP6 applications. This is also the case when I add them to the JVM classpath (I know this is bad - but it was a last resort!).
Hoping someone can help me redeploy irj with my application that will resolve problem 2! If not, maybe some advice on problem 2?
Cheers,
Scott...Hi Scott,
THis isnt an answer to ur Question, but could u tell me which jar files are needed for the packages:
com.sap.portal.pcm.system.ISystems
com.sap.portal.pcm.system.ISystem
and under which path I coul dfind them.
Thnx
Regards

Dynamic Class Loading and Unloading
I am trying to create a system where the class name and method name is
picked up from a meta-data database and executed.
This was accompanied using Dynamic Class loading. I tried to extend this to
support versioning of meta-data. Here depending on the version of meta-data
different libraries can be loaded and different implementations of object
with the same name can be executed. This does not seem to work with Forte
3.0.
When the second Library is loaded the method execution does not work.
(Even though the unload flag on the LoadLibrary is set)
If the application is stopped and restarted pointing to the second library
there is no problem. In a running application a dynamically loaded library
does not seem to unload and reload a new library for the same class names.
Has anyone tried sometime similar, is there a workaround for this type of
problem.

Dynamic Class Loading and Stubs
How Dynamic Class Loading is used on Java RMI, since stubs are generated on clients using Reflection API?
I was reading Dynamic code downloading using JavaTM RMI (http://java.sun.com/javase/6/docs/technotes/guides/rmi/codebase.html), it seems to be out of date.
For example, "The client requests the class definition from the codebase. The codebase the client uses is the URL that was annotated to the stub instance when the stub class was loaded by the registry. Back in step 1, the annotated stub for the exported object was then registered with the Java RMI registry bound to a name.""Enhancements in J2SETM 5.0
Dynamic Generation of Stub Classes
This release adds support for the dynamic generation of stub classes at runtime, obviating the need to use the Java(tm) Remote Method Invocation (Java RMI) stub compiler, rmic, to pregenerate stub classes for remote objects. *Note that rmic must still be used to pregenerate stub classes for remote objects that need to support clients running on _earlier versions_.*
When an application exports a remote object (using the constructors or static exportObject methods(1) of the classes java.rmi.server.UnicastRemoteObject or java.rmi.activation.Activatable) and a pregenerated stub class for the remote object's class cannot be loaded, the remote object's stub will be a java.lang.reflect.Proxy instance (whose class is dynamically generated) with a java.rmi.server.RemoteObjectInvocationHandler as its invocation handler.
An existing application can be deployed to use dynamically generated stub classes unconditionally (that is, whether or not pregenerated stub classes exist) by setting the system property java.rmi.server.ignoreStubClasses to "true". If this property is set to "true", pregenerated stub classes are never used.
Notes:
* If a remote object has pre-5.0 clients, that remote object should use a stub class pregenerated with rmic or the client will get an ClassNotFoundException deserializing the remote object's stub. Pre-5.0 clients will not be able to load an instance of a dynamically generated stub class, because such a class contains an instance of RemoteObjectInvocationHandler, which was not available prior to this release.
* Prior to the J2SE 5.0 release, exporting a remote object would throw a java.rmi.StubNotFoundException if the pregenerated stub class for the remote object's class could not be loaded. With the added support for dynamically generated stub classes, exporting a remote object that has no pregenerated stub class will silently succeed instead. A user deploying a server application to support pre-5.0 clients must still make sure to pregenerate stub classes for the server's remote object classes, even though missing stub classes are no longer reported at export time. Such errors will instead be reported to a pre-5.0 client when it deserializes a dynamically generated stub class.
(1) The static method UnicastRemoteObject.exportObject(Remote) is declared to return java.rmi.server.RemoteStub and therefore cannot be used to export a remote object to use a dynamically generated stub class for its stub. An instance of a dynamically generated stub class is a java.lang.reflect.Proxy instance which is not assignable to RemoteStub."

This is the code i'm using and i've encountered following problem, if i put this code into an application without webstart, anything works fine, but with webstart i'll get a: java.lang.NoClassDefFoundError
Then i've put the MyFrame-classes into the downloaded jar-file, but this won't work either, i'll get a ClassCastException.
What do i have to do, to become it working ?
Thanks for any conclusions and help.

Dynamic Class Loading with interface
Hello
I would appreciate any help on the following problem.
I need to load all classes in a particular directory and its subdirectories (top directory is known but not in the classpath) which implement a predefined interface. At the moment I am using a lot of reflection to accomplish this and believe it can be avoided somehow using the fact that I know these classes have to implement a predefined interface.
At the moment, I am searching through the directory and subdirectory, loading all names of classes into a vector using a custom URLClassloader, and then load all classes in the vector into modulecontainers to populate a defaultmutabletree which is displayed on the gui.
I'm sure that knowing the interface means there's a more straightforward way.

Hi all,
Couple of questions. Is dynamic class loading using classloaders supported in any, if not all versions of J2ME? I guess I should ask first, what exactly does J2ME cover? I see KVM, but do watches and PDA's, set top boxes, refrigerators and so forth all run the same J2ME JVM? Or are their "less feature full" versions? I was hoping the J2ME spec would be the "lowest common denominator" to program for, but I thought I read somewhere that small devices like watches may even have a "smaller" J2ME JVM or something, less capable. So can I write code for J2ME and it will run on all small devices like cell phones, pda's, and so forth? Or is there another J2ME version, perhaps small than J2ME.
So, from what I have found so far, it appears dynamic class loading is done at startup from a DB (of sorts) as opposed to being able to dynamically find/load classes. If this is so, is there any way to support downloading and reloading new classes like you can with J2SE, such as the hot-swap feature of web servers? Does Class.forName() at least work in that you can "replace" a class with a new version, even if it is not able to have a separate classloader instance? My guess is that J2ME supports only a single classloader space, but I thought I read somewhere that Class.forName() is available. J2ME API shows it I believe, but I could be wrong.
Any help on this topic would be appreciated.
Thanks.Dynamic class loading is not available in most (if not all) J2ME profiles and configurations. Class.forName() is available (at least in the MID profile), but not to be used for dynamic class loading. It can be used when using device-specific APIs where you can try to load a class containing device specific methods (for example a class that works only on certain Nokia phones, and has methods playSound() and vibrate(), which are not available in MIDP), and if you catch a ClassNotFound exception you can load a class that doesn't use the device specific APIs and contains stubs of the methods, or you can disable certain features in you application that need those features. For an example implementation you can have a look at Nokia's Block Game example (available from their developer site - http://www.forum.nokia.com/main.html).
As for your other more general questions about different JVM's and such, you should read all about the different configurations and profiles available in J2ME (plenty of information using in the J2ME link on this site). -
Dynamic class loading when CODEBASE is unreachable. A bug?
Let us suppose that we have a large-scale distributed application with ca. 1000 participants communicating via RMI and utilizing dynamic class loading. As we all know, a HTTP code server must be available for this purpose in order to provide dynamically downloaded code, usually the communication proxy code of remote objects. In a real-world scenario, the HTTP server will never be 100% available, so that we will have cases that a Java process will not be able to download the necessary Java classes, causing the RMI communication to fail with a ClassNotFoundException or similar exception. In such a case, a robust application would perform some recovery activities and retry the remote call. Eventually, the HTTP server becomes available again and the distributed system recovers automatically. This seems to work fine with J2SE 1.4.2_10, but not with 1.4.2_11 and newer versions. Considering Java 5, the Update 9 exhibits the same problem.
For tracking down the problem, I've written a simple distributed test application, consisting of a client and a server. A server listens on a port, and sends a MarshalledObject to the client. The code of the MarshalledObject is annotated with the value of the "java.rmi.server.codebase" system property. The annotation contains an URL of the JAR file containing the code of the original object. The client connects to the server, reads data form the socket and unmarshalls the original object. This is basically the same procedure as when objects are accross the wire as arguments/return values/exceptions by the RMI/JRMP engine. This procedure is repeated forever in the loop. Due to the fact that the client's CLASSPATH doesn't contain the code of the original object, this code should dynamically be loaded from the HTTP server using the appropriate annotation provided by the server.
If we start the client while the HTTP server is down, the client will keep generating the ClassNotFoundException over and over again, as expected. So far, so good. If we now start the HTTP server while the client is still running, we will observe different behaviors, depending on the version of the client's JVM:
1. In J2SE 1.4.2_10, the client will download the code from the HTTP server and successfully unmarshal the original object sent by the server. ClassNotFoundExceptions will not be generated again.
2. In J2SE 1.4.2_11, 1.4.2_12 and 1.4.2_13 as well as in J2SE 5.0 Update 9, the client will continue generating ClassNotFoundExceptions. Analysis of the HTTP server's access log shows that there were no attempts to download the JAR file required for unmarshaling the object sent by the server.
It seems that in the newer JVM versions the RMI engine remembers URLs which have failed and does not attempt to access them anymore. Althogh this may have some advantages considering the overall network load, the dynamical class loading becomes practically useless in productive large distributed systems. The very first attempt to load the codebase of the communication peer must succeed, otherwise the whole process must be restarted for the communication to work, which is a very expensive (and for most customers unacceptable) operation in terms of preformance and resources usage.
Should this be seen as a bug or a feature of the JVM? What do you think?

Dynamic class loading from String name
Hello all,
I have a question for dynamic class loading:
If I have a String variable that represents a class name, how can i use it to make dynamically an object of the class tha the string variable represents?
For example i have a string like this
String classname="String";
Using this i want to make a new String object .
Can anyone tell me how can i do this(example plz)?I have worked out the code and this works fine:
import java.lang.*;
class dynamictestname{
public dynamictestname() {
public static Class test(String objname){
try{
Class theClass = Class.forName(objname);
return theClass;
} catch (ClassNotFoundException e)
throw new NoClassDefFoundError (e.getMessage());
public static void main (String [] args){
String classname="java.lang.String";
Class thisClass=dynamictestname.test(classname);
try{
Object instance = thisClass.newInstance();
}catch(InstantiationException e){
}catch(IllegalAccessException ie){
}The new problem i 've faced is that i can't instatiate a new object by the class i have created.I saw some examples with use of the java.lang.reflect but this class i used with user created classes which have methods that the user wants to run dynamically.
I just want to make an object from the class and give it a value.
For example if the object i have created with the
Object instance = thisClass.newInstance();is an object of java.lang.String class
how can i do something like this below dynamically from instance object :
String x="TEST ";
Thanks for the help.. -

An issue with authentication and authorization on ISE 1.2
Hi, I'm new to ISE.
I have an issue with authentication and authorization.
I have ISE 1.2 plus patch 6 installed on VMware.
I have built-in Windows XP supplicant and 2960 cisco switch with IOS c2960-lanbasek9-mz.150-2.SE5.bin
On supplicant I use EAP(PEAP) with EAP-MSCHAP v2.
I created authentication and authorization rules with Active Directory as External Identity Source. Also I applied authorization profile with DACL.I login on Windows XP machine under different Active Directory accounts. Everything works fine (authentication, authorization ), but only for several hours. After several hours passed , authentication and authorization stop working . I can see that ISE trying authenticate and authorize users, but ISE always use only one account for authentication and authorization . Even if I login under different accounts ISE continue to use only one last account.
I traied to reboot switch and PC,but it didn’t help. Only rebooting of ISE helps. After ISE rebooting, authentication and authorization start to work properly for several hours.
I don’t understand is it a glitch or I misconfigured ISE or switch, supplicant?
What should I do to resolve this issue?

endYes. Tried that (several times) didn't work. 5 people in my office, all with vers. 6.0.1 couldn't access their gmail accounts. Kept getting error message that username and password invalid. Finally solved the issue by using Microsoft Exchange and "m.google.com" as server and domain and that the trick. Think there is an issue with imap.gmail.com and IOS 6.0.1. I'm sure the 5 of us suddently experiencing this issue aren't the only ones. Apple will figure it out. Thanks.

iOS 7.0.3 did not fix the mirroring issue with ATVs and AirServer. Anyone have an idea what needs to be done? The only solution we have found is to reboot the iPad. We don't have the option of restarting the wireless as so many people are on and it would further disrupt classes.

Photo file issues with iWeb and Aperture....also too much duplicating!!
A little background, before I get into my iWeb issue.....
Years ago I tried iPhoto, but I didn't like how it duplicated all my photo files and I wasn't very fond of the file structure it created. Years later (last month) I got Aperture. Aperture (still has a long way to go) also duplicates all your files and places them in their own file structure. If I can get along with Aperture (and if it will get along with my other programs), I won't mind putting all my files into the file structure it creates. But for now, I still have my original files in the original file structure I have had for many years as a back up.
On to my issue with iWeb and Aperture....
To add photos to iWeb, you can either go into the iWeb media center or you can drag and drop photos from other locations.
1st: iWeb media center
To get my photos into the media center, I would have to load them into iPhoto (iP 6 does allow you to keep your original file structure, but it still creates .jpg files, which fills up your hard-drive. More duplicates I don't need or want). So that is out for me. iP6 will let you view and use your Raw files.
Another way is to drag and drop your file structure directly into the media center window. I don't think this duplicates any files (at least I haven't been able to find any), but it takes an awfully long time to thumbnail all your photos (several hours and still waiting for 22K + files). Also, it won't show any Raw files. Again, out for me.
Aperture won't let you drag and drop its library into the media center at all. So if I was to move all my files into the Aperture Library, I wouldn't be able to access them for iWeb at all.....Out for me.
2nd: Drag and Drop
I was able to drag and drop Raw files directly into iWeb from C1 Pro, Adobe Bridge and Adobe Lightroom.
As I said before, I am trying to move over to Aperture. However, Aperture won't let me drag and drop photos. What is the deal here??? These are both Apple programs and they won't play nice with each other. Very annoying.
Anyway, I put a link below to my iWeb test webpage I made. All the photos were Raw files that I did a drag and drop from C1 Pro, Adobe Bridge and Lightroom. There were no problems with the publishing.
http://web.mac.com/phil_navarro/iWeb/Site%202/Drag%20and%20Drop%20test.html
So, does anyone know if they can get photos from Aperture to work?? Thanks for any responses.

G5 Desktop Mac OS X (10.4.4)Jedi,
Perhaps you are right.
I am not a web developer and I will never be. I don't feel like spending countless hours learning how to use Dreamweaver or some other Pro web app. iWeb looked like a way to start making websites of my photos for my friends and family (much easier and better than Home Page on .Mac). All I was asking was for a way to drag and drop my photos (especially Raw files) with Aperture. Which I can do with Lightroom, Adobe Bridge and C1 Pro, and without using iPhoto.
I am not a Pro photographer either, but I purchased Aperture based on what was advertised on the Apple website. From that ad, Aperture fit my photo needs almost to a tee. I am looking to adjust Raw files, Crop, Archive and keep my use of Hard Disk space down to a minimum. I can use Photoshop for the other 5% of things I do. However, Aperture has some issues (if you own it, then you already know. If you don't, you can read the Aperture Forum) This is one of the reasons I never went to iPhoto for archiving. I didn't like the way it duplicated all my files, taking up more disk space and its file structure. So even though Aperture won't play nice with other programs, I was surprised that it wouldn't play nice with any Apple programs.
After reading your post and based on what you are saying, everyone either needs to have/learn/use Pro apps only or have/learn/use iApps only. Don't Cross the Streams!!
I guess that means Apple will need to fix DVD Studio Pro. It uses photos that are in your iPhoto library and music from iTunes (iApps in a Pro app??....for shame...."it was never intended"). Also, DVD SP won't read the Aperture library. Does that mean there are 3 platforms? Pro, iApp and Mediocre??
Now I have 2 questions:
1. Can someone please tell me which apps are Pro and iApp, or if there is Mediocre? I don't want to mix them up and "Cross the Streams".
2. Again....is there anyway to use Aperture with iWeb?
TIA,

Dynamic class loading failed, why?
Hi there!
We are using WebLogic 5.1 togehter with Apache1.3.22/Tomcat4.01. It all worked
fine for about 2 month. All of a sudden, dynamic class loading refuses to work.
From one day to the other I got the excpetion: javax.naming.CommunicationException.
Root exception is weblogic.rmi.UnmarshalException: Unmarshalling return
- with nested exception:
[java.lang.ClassNotFoundException: class com.dsh.egb.aks.betrieb.ejbs.AnmeldenEJBHomeImpl_ServiceStub
previously not found]
Why does this happen? I can not remember having touched any properties.
Please help,
HeinerIf you were relying on client network classloading stubs from WebLogic, you
can test if it still works by pointing your browser to
htpp://yourweblogic:7001/classes/com/dsh/egb/aks/betrieb/ejbs/AnmeldenEJBHomeImpl_ServiceStub.class
