"ClassCastException when modifiying JOptionPane behaviour" To view the discussion, visit: https://community.jboss.org/message/725909#725909 -------------------------------------------------------------- I'm triying to modify the JOptionPane behaviour to log all the user responses. If do it when the class is loaded with HotsSapper is OK, but i can't do it whith the HotSwapper because the application it's launched by Java Web Start and i haven't be able to open the needed socket. If i try to modify the class before it's loaded i have an ClassCastException throwed by BasicOptionPaneUI. there is the code i use: public class Test2 { public static void main(String[] args) throws Exception { ClassPool cp = ClassPool.getDefault(); CtClass cc = cp.get("javax.swing.JOptionPane"); CtMethod[] methods = cc.getMethods(); for (CtMethod method : methods) { if (method.getName().equals("showConfirmDialog")) { if(method.getLongName().equals("javax.swing.JOptionPane.showConfirmDialog(java.awt.Component,java.lang.Object, java.lang.String,int,int,javax.swing.Icon)")){ String after = "System.out.println(\"User answered: \" + $_ );"; method.insertAfter(after); } } } try{ Class c=cc.toClass(); c.newInstance(); }catch(CannotCompileException ex){ ex.printStackTrace(); } JOptionPane.showConfirmDialog(null,"Yer or Not?"); } } Why is this happening? how can i fix it? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/725909#725909] Start a new discussion in Javassist at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2062]
