问题 I'm getting InvocationTargetException and NullPointerException when attempting to bind to custom class run by Task. I have working examples of binding to library classes ObeservableList, Long, Integer etc but now need to bind to values of custom class. I created TaskOutput class that includes StringProperty for binding purposes as follows: public class TaskOutput { private final StringProperty textValue = new SimpleStringProperty(); public TaskOutput(String textValue) { this.textValue.set

问题 Just like the title says: Why do I get java.lang.reflect.InvocationTargetException in browser but not in eclipse applet viewer? When I run my applet (yes, i know applets are outdated) in the browser using html to load it, i get the java.lang.reflect.InvocationTargetException error. I read that this happens when the HTML is trying to load something that is not an applet, but it works when I run it as an applet in eclipse (brings up eclipse java applet viewer and works perfect...that is what

问题 I am developing app in Xamarin Android and have a very strange problem: Breakpoints and Exceptions have stopped working properly. When I set a breakpoint it never gets hit. I have set breakpoints all over my project but none of them were hit. This happens in Visual Studio and in Xamarin Studio as well. I also have second and more annoying problem, every time there is an exception, it throws totally unhelpful "java.lang.reflect.InvocationTargetException" exception in Xamarin Studio and "An

问题 As per the javadocs, InvocationTargetException.getCause() can be null: Returns the cause of this exception (the thrown target exception, which may be null). But the documentation also says that it wraps an existing exception: InvocationTargetException is a checked exception that wraps an exception thrown by an invoked method or constructor. So it seems to me that InvocationTargetException.getCause() can never be null . Am I missing something? UPDATE Yes, I missed something -- the default

问题 I have created a program to convert text to xml by using ReverseXSL API. This program is to be executed by an application by calling static method ( static int transformXSL ). I am able to execute and produce output with running from Eclipse. However, When I ran program (jar) by using application it stuck somewhere and I couldnt find anything. Then, I debugged by "Debug as...-> Remote Java Application" in Eclipse from Application and found "InvocationTargetException" at ClassLoaders

问题 I am making a 2D game in Android with Cocos2D, written in Java. Here is my code for the main stuff: public void gameLoop(float dt) { //Player Gravity if(canExecuteMovement(0, 6)) { guy.moveY(6); } //Player Movement if(direction == 1) { if(canExecuteMovement(-3, 0)) guy.moveX(-3); } else if(direction == 2) { if(canExecuteMovement(3, 0)) guy.moveX(3); } } private boolean canExecuteMovement(int xChange, int yChange) { int projectedX = guy.getBounds().left + xChange; int projectedY = guy

问题 I am currently using Reflection to execute a set of methods in classes which reside in a different project than the one I am working on. These methods will in turn call other methods within this project. Although the method calling is succeeding, an InvocationTargetException caused by NoSuchMethodError is being thrown. I am presuming that this occurred because the methods I am calling using reflection call other methods. For this reason I have added to the class path the other project but
