Hello, I'm trying to send objects from bundles over a dedicated communication bundle to an other framework. For communication I use Java standard serialization (with ObjectStreams) over TCP/IP. Communication flow is the following: A sender-bundle will pass serializable objects to a transmit-sender which will serialize the objects and ...
Is there a guarantee that (the default, system) Java class loader doesn't attempt to load classes that aren't referred to in the code being run? A couple of examples of what I mean: I'm using a framework.jar which I know to contain references to another library.jar's classes in it, but I'm using only such part of the framework that doe...
hi, I am confused at a point while running my application. My application consists of EJB and servlets. i need to know, whether the class loader for these application types is same or different. I am using weblogic as application container. Please help me. ...
The classes: public interface Inter { ...some methods... } public class Impl implements Inter { ...some implementations... } The issue is that for some freaky reason, I have to load the interface Inter with child ClassLoader and the implementation class Impl with parent ClassLoader.

Hi, I would like to make a single Android app for multiple Android versions (possibly every one of them) My problem is that I want to check what is the version of Android the app is currently running on, and dynamically load a class which is version dependent. This part should be ok. I just wonder how I can achieve that without compila...
When using Scala RemoteActors I was getting a ClassNotFoundException that referred to scala.actors.remote.NetKernel. I copied someone else's example and added RemoteActor.classLoader = getClass.getClassLoader to my Actor and now everything works. Why is this necessary? ...
In the parent delegation model for loading classes, I know that loadclass() is invoked on the parent, all the way to the top of the class-loader hierarchy (assuming the class is not loaded). At which point the topmost parent classloader's findClass is invoked. If this class is not found, how is the control transferred to the next classl...

How can I use JMock on the Android? I've several posts saying its not possible, but surely there's some way to do it? The issue seems to be getting the Android to even recognize the JMock jar file. So maybe there's a solution with putting the jar into assets and making a custom class loader? That seems like a lot of trouble, but do...
I am attempting to load classes dynamically into a component. I am using a file chooser to select the .JAR file that will be loaded and then a option pane to get the name of the class. I have trawled the internet looking for how to convert a java file to a URL in order to load it in URLClassLoader and I have come up with: File myFile =...

I have a simple RMI 'compute' server application (similar to this) that accepts objects of some interface type from clients over RMI, executes the compute() method of the received object and returns the result over RMI to the remote client. The jobs are 'one-offs' and there is no interaction between the different jobs or between objects...

You'll probably ask, why would I want to do that - it's because I'm using a class (from an external library) which does stuff in its static initializer and I need to know whether it's been done or not. I looked at ClassLoader, but didn't find anything that looked useful. Any ideas? ...
Hi, How can I call the method of an object that has already been loaded in the JVM using reflection? I tried Class myClass = Class.forName("myClass"); Method m = com.test.class.getDeclaredMethod("getValue",new Class[] {}); Object result = m.invoke(myClass,null); but i get java.lang.IllegalArgumentException: object is not an instance ...
