[Javassist user questions] - Using Javassist inside Mojo
by ad-rocha
Hi all,
Iôm trying to use Javassist inside a Mojo. The code is very simple, but the program fails with a java.lang.ClassNotFoundException.
First I collect all dependencies of Maven project:
| // maven dependencies
| List<String> classpath = new ArrayList<String>();
| classpath.addAll(project.getCompileClasspathElements());
| classpath.addAll(project.getTestClasspathElements());
| Set<Artifact> artifacts = project.getDependencyArtifacts();
| for (Artifact artifact : artifacts) {
| classpath.add(artifact.getFile().getAbsolutePath());
| }
|
After that, I append all dependencies to ClassPool:
| ClassPool pool = ClassPool.getDefault();
| // add dependencies to classpath
| for (String element : classpath) {
| pool.appendClassPath(element);
| }
| // get class
| CtClass cc = pool.get(className);
|
The error is caused by method.getAnnotations() call below:
| ...
| if (object instanceof CtMethod) {
| CtMethod method = (CtMethod) object;
| annotations = method.getAnnotations();
| ...
| }
|
The error is: java.lang.ClassNotFoundException: org.testng.annotations.BeforeMethod
But, org.testng.annotations.BeforeMethod is inside testng-5.8-jdk15.jar, wich was added to classpath. What am I doing wrong?
Thanks in advance,
Andre

[JBoss AOP] - Deploy AOP Application on JBOSS AS
by wandxinho
Hello, i was join jboss aop and a standalonne aplication works perfectly, but when i was deploy a web application on JbossAS it doesnt work. Please, wht is necessary for my application work on JbossAS ? i just follow this steps:
To upgrade your jboss instance:
1) Copy the contents of the lib folder into the JBoss-5.x/lib/ folder
2) Copy the jboss-aop-jdk50.deployer over the JBoss-5.x/server/xxx/deployers/jboss-aop-jboss5.deployer/ folder
Note that this will not replace the jboss-aspect-library.jar, which is tied to application server version
my JbossAS is 5.0.1GA and my aop version is 2.0.0GA.
and the error is
15:44:36,912 INFO [TomcatDeployment] deploy, ctxPath=/HelloWorldAOP
15:44:47,877 ERROR [[MyServlet]] Servlet.service() for servlet MyServlet threw exception java.lang.IllegalArgumentException: Can not set static org.jboss.aop.MethodInfo field Apecto.Actions.aop$MethodInfo_alterar_N_6055099272587152912 to java.lang.ref.WeakReference
Thanks!

[Installation, Configuration & DEPLOYMENT] - Re:

here's that line, where exception is being thrown (line 516), although I don't think it would help:
startupObject = withPropFileConstructor.newInstance(args);
|
the code loads some startup classes in that method and one of them requires a context initialization, which can't be performed because (I guess) the proper JAR file is not visible to the current classloader (why??).
It's an old legacy app and I can't really change much in this scheme. It works properly with Jboss 3.2.7.
My guess is I need to reference the jar file with that NamingContextFactory somewhere in Jboss config file. But it is already present in jboss common\lib\ folder and my current conf\jboss-service.xml has standard references to load default Jboss libs:
<classpath codebase="${jboss.server.lib.url}" archives="*"/>
| <classpath codebase="${jboss.common.lib.url}" archives="*"/>
|
so, what could be a reason for this class not being visible?
