aw does not work on jdk 1.5?

 

I wrote an simple Advice to print a hello world message, and use xml model
to bind it to a pointcut.

 

<aspectwerkz>

    <system id="examples">

        <!-- ============================================= -->

        <!--  Advices                                      -->

        <!-- ============================================= -->

        <advice-def name="hello"

                    class="HelloAdvice"

                    deployment-model="perJVM"/>

        <!-- ============================================= -->

        <!--  Concrete aspects                             -->

        <!-- ============================================= -->

        <aspect name="Hello">

            <pointcut-def name="hello" type="method"

                    pattern="int Hello.hello(int)"/>

            <bind-advice pointcut="hello">

                <advice-ref name="hello"/>

            </bind-advice>

        </aspect>

    </system>

</aspectwerkz>

 

It works well when I use jdk 1.4

C:\j2sdk1.4.1_05\jre\bin\java

00,server=y -Xdebug

But when I use jdk 1.5 to compile and run the code, it doesn’t work, and
there is no error message.

If you want to access Java 1.5 metadata, use Java 1.5 API and class
retention policy for your metadata.

This issue does not relates to how AspectWerkz currently handles doclets for
self defined Aspects.

 

The only restriction for now is that AspectWerkz does not support yet Java
1.5 metadata *to define its own aspects*.

Thank you for your answer.

I want read some metadata in some Advice classes. Since this aop framework
do not support java 1.5 metadata, would you tell me if there is another way
to write and read some metadata from the class? Or if there is any other aop
framework support java 1.5 metadata.

Thanks

I forgot to mention we will have "Java 1.5 metadata" (and not doclet)
support for Aspect development in around october 2004 at latest.

I used jdk 1.5 to compile a simple aspect like this

 

 

import org.codehaus.aspectwerkz.attribdef.aspect.Aspect;

import org.codehaus.aspectwerkz.attribdef.Pointcut;

import org.codehaus.aspectwerkz.joinpoint.JoinPoint;

import org.codehaus.aspectwerkz.joinpoint.CallerSideJoinPoint;

import org.codehaus.aspectwerkz.joinpoint.MethodJoinPoint;

 

import java.util.Map;

import java.util.HashMap;

 

 

@Aspect("perInstance")

public class CachingAspect extends Aspect {

 

    // ============ Pointcuts ============

     @Call("*->int Pi.getPiDecimal(int)")

    Pointcut invocationCount;

 

     @Before("invocationCount")

    public void invocationCounter(final JoinPoint joinPoint) throws
Throwable {

        CallerSideJoinPoint jp = (CallerSideJoinPoint)joinPoint;

        System.out.println("invocation me");

        joinPoint.proceed();

    }

 

    protected Map m_cache = new HashMap();

}

 

But I got some compile errs.

 

compile:

    [javac] Compiling 1 source file to
E:\NieLinJie\working\testaspectw\classes

    [javac] E:\NieLinJie\working\testaspectw\src\CachingAspect.java:17:

    [javac] symbol  : class Call

    [javac] location: class CachingAspect

    [javac]       ^

    [javac] location: class CachingAspect

    [javac]      @Before("invocationCount")

    [javac]       ^

    [javac] 2 errors

 

 

 

Would you pls tell me where to find the declarations of the annotation types
(such as @Aspect, @Call, @Before).

Thanks.
