[JBoss-user] [JBoss AOP] - Re: Dynamically adding annotated aspect classes without
Hi,
I'm not sure if I'm doing something wrong in the way that I get the ClassFile
object? but I'm getting some strange behaviour using this new feature.
Using the annotated-aspects test as a starting point I run the test specifying
the classpath using -Djboss.aop.class.path=myclasspath - all works as expected.
I adjusted Driver.java it so it looks as below and removed
-Djboss.aop.class.path from the JVM args. The aspects are no longer added as
expected.
If you remove the try-catch block around the POJO creation and method/field
calls the method advice is added but not the ones for the contructor or field
access. No info/error message are thrown is either case.
public class Driver
| {
|public static void main(String[] args)
|{
|
| try {
| AspectAnnotationLoader aspectLoader = new
AspectAnnotationLoader(AspectManager.instance());
|
aspectLoader.deployClassFile(getClassFile(MyAspect.class));
| } catch (IOException e) {
| e.printStackTrace();
| } catch (Exception e) {
| e.printStackTrace();
| }
|
| try{
| System.out.println(--- pojo constructor ---);
| POJO pojo = new POJO();
| System.out.println(--- pojo.method(); ---);
| pojo.method();
| System.out.println(--- pojo field write ---);
| pojo.field = 1;
| System.out.println(--- pojo field read ---);
| int i = pojo.field;
| }catch(Exception e){
| e.printStackTrace();
| }
|}
|
|
|
| public static ClassFile getClassFile(Class clazz) throws IOException {
| String tName=clazz.getSimpleName() + .class;
| if (clazz.getPackage() != null) {
| String tPackageName = clazz.getPackage().getName();
| String tClassName = clazz.getSimpleName();
| tPackageName = tPackageName.replace('.', '/');
| tName = tPackageName + '/' + tClassName + .class;
| }
| InputStream input =
clazz.getClassLoader().getResourceAsStream(tName);
| BufferedInputStream fin = new BufferedInputStream(input);
| ClassFile cf = new ClassFile(new DataInputStream(fin));
| return cf;
| }
|
|
| }
I ran all these tests within Eclipse and using the runtime instrumentor and
latest code from jboss-head.
regards
James

[JBoss-user] [JBoss AOP] - Re: Dynamically adding annotated aspect classes without
Its just dawned on me I need to prepare the objects for runtime instrumentation as in the dynamic-aop example using a jboss-aop.xml defined in the jvm args using -Djboss.aop.path=jboss-aop.xml. ?xml version=1.0 encoding=UTF-8? | aop | |prepare expr=all(POJO)/ | | /aop When I do that it works fine, but its was hard to find. Thanks again for adding this feature.

Thanks for this, I haven't had a chance to play with it yet but hopefully will do next week.

I have added this to cvs The API is | void AspectAnnotationLoader.deployClassFile(javassist.bytecode.ClassFile) | void AspectAnnotationLoader.undeployClassFile(javassist.bytecode.ClassFile) | See the deployInputStreamIterator() method for how to obtain the class file.

[JBoss-user] [JBoss AOP] - Re: Dynamically adding annotated aspect classes without
I see that AspectAnnotationLoader iterates through the list of FileInputStreams of the classes in the jboss.aop.class.path turning each one into javassist.bytecode.ClassFile before checking each one for annotations. I think a public method on AspectAnnotationLoader that allows the user to do something like; aspectAnnotationLoader.addAnnotatedClass(MyAnnotatedClass.class); would be useful, for me at least :) best wishes James View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3946923#3946923 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3946923 --- All the advantages of Linux Managed Hosting--Without the Cost and Risk!
