[jboss-user] [JBoss AOP] - Re: jboss-aop.xml is trying to apply an already existing met

Thu May 15 12:51:56 EDT 2008

Hello Kabir.

Thank you for your response. I really appreciate your help.

Well... what I posted is all I have that talks about VacanteVO in my AOP coding. I made sure of it. (unless I made a mistake while checking it... a lot of times, hahaha)

I'm adding a separate mixin for each class that need to get new methods and/or attributes. There are two classes (VacanteVO and CriteriosBusquedaConsultarVacantesVO) that have almost the same attributes, but I don't think that should matter.

Following is the process I do to deploy my project. In case you find something wrong, or have a comment.

I enabled the verbose flag in the file:
C:\jboss-4.2.1.GA\server\default\deploy\jboss-aop-jdk50.deployer\META-INF\jboss-service.xml

Every time I test it, I do the following:
a) Stop the jboss server
b) Delete the the following directories or files, just to make sure there is nothing left form a previous test:
  C:\jboss-4.2.1.GA\server\default\data\
  |   C:\jboss-4.2.1.GA\server\default\log\
  |   C:\jboss-4.2.1.GA\server\default\tmp\
  |   C:\jboss-4.2.1.GA\server\default\work\
  |   C:\jboss-4.2.1.GA\server\default\deploy\bolsaDeTrabajo-1.0-SNAPSHOT.ear
  |   C:\jboss-4.2.1.GA\server\default\deploy\bolsaDeTrabajo-ds.xml

c) I start the server and when it's finished starting, I make a copy of
  C:\jboss-4.2.1.GA\server\default\log\server.log

d) I copy the ear file to:
  C:\jboss-4.2.1.GA\server\default\deploy\bolsaDeTrabajo-1.0-SNAPSHOT.ear

e) When it finishes the deploy, I make another copy of the log file

Analizing the log file

In the log file copied after deploy, I can't find any message saying something like:

but talking about VacanteVO

Here are the lines containing VacanteVO (with the linenumber at the beginning)

So, apparently it's being waved before line 33559, because line 33566 is reporting "getRequisitos ()Ljava/lang/String;] matches no pointcuts". That means it already has a getRequisitos method, Right?

I don't understand enough the log messages, maybe.

I'm completely clueless about what could cause this problem.

----------------

If you have some free time, want and can give me a hand, please download the source code, .ear file and log file from:

http://www.mitalteli.com/thesis-2008/

And take a look. I hope it's a simple rookie mistake. (I really hope)

Note that I deleted all the ".class" files and the uncompressed ear from the sources zip (bolsaDeTrabajo-200805150947.zip) .

You can find the jboss-aop.xml at:

<path to the uncompressed zip>\bolsaDeTrabajo\aop\src\main\resources\META-INF

You can find the aop sources at:

<path to the uncompressed zip>\bolsaDeTrabajo\aop\src\main\java\com\mitalteli\bolsaDeTrabajo\useCaseSlices\specific\consultarVacantes

The sources that are being modified with the AOP coding are spread in the directories:

[common|core|web]\src

and 

[common|core|web]\target

If you need to compile, I have some tweeks to do every time. So, once you are in the unziped source in a cmd black window, execute:

mvn clean
mvn install
copiarCapaPresentacion.bat
mvn -f web/pom.xml
mvn -f app/pom.xml

and to deploy it:

mvn -o -f app/pom.xml -Ddeploy

The .ear file gets created at:

<path to the uncompressed zip>\bolsaDeTrabajo\app\target

Thank you very much in advance.

Ely
