I need aspectize some X classes at runtime, without using SystemClassLoader and
jboss-aop.xml,
You couldn?t find such a sample in the examples folder and tried to run one of
your examples in that way.
I have custom URLClassLoader which loaded with classpath of JBossAOP jars and
that classes the code I have used
public static void main(String[] args) {
|
| try {
| AdviceBinding binding = new AdviceBinding(
|
| "call(int java.util.ArrayList->size()) AND withincode(void
Driver->caller())", null);
|
|
|
| binding.addInterceptor(CallerInterceptor1.class);
|
|
|
| AspectManager.verbose = true;
|
|
|
| AspectManager am = AspectManager.instance();
|
|
|
| am.addBinding(binding);
|
|
|
| org.jboss.aop.standalone.SystemClassLoader sc = new
org.jboss.aop.standalone.SystemClassLoader( createURLClassLoader() );
|
|
|
| am.registerClassLoader(sc);
|
|
|
| byte[] b = am.translate("Driver", sc);
|
|
|
| Class c = sc.defineClassFromBytes("Driver", b, true);
|
| System.out.println("c="+c);
|
| Method m = c.getMethod("main", new Class[] {String[].class});
|
|
|
| m.invoke(null, new Object[] {new String[] {} });
|
|
|
| }
|
| catch (Exception ex) { ex.printStackTrace(); }
|
| }
|
|
|
|
|
| static URLClassLoader2 createURLClassLoader() throws Exception {
|
| URL urls[] = null;
|
|
|
| File f = new File("resources/aop/jars"); //the path where JBossAOP jars
and that classes located
|
|
|
| if (f.isDirectory()) {
|
| File ff[] = f.listFiles();
|
| urls = new URL[ff.length];
|
|
|
| for (int i = 0; i < ff.length; i++) {
|
| urls = ff.toURL();
|
| }
|
| }
|
|
|
| return new URLClassLoader2(urls, null);
|
| }
It fails to transform bytecode and return null,
Could you help me and send similar working code or indicate where I should look
for that.
