Hi .
Greetings.
I am new to AspectWerkz.
I am trying with following example(in Eclipse , without Plugin) :
Target class:
public class Target {
public void step1() {
System.out.println(" --> invoking step1");
step2();
}
public void step2() {
System.out.println(" --> invoking step2");
}
}
Aspect Class :
public class Aspect_Tenant1 {
/**
* @Expression execution(void examples.cflow.Target.step1())
*/
Pointcut myDynamicAspect;
/**
* @Before myDynamicAspect
*/
public Object myAdvice(final JoinPoint joinPoint) throws Throwable {
Object result =3D joinPoint.proceed();
System.out.println(" --> ADVICE : invoking advice triggered by ste=
p3 for Tenant 2");
return result;
}
AOP.XML in META-INF folder under src:
<!DOCTYPE aspectwerkz PUBLIC
"-//AspectWerkz//DTD//EN"
"http://aspectwerkz.codehaus.org/dtd/aspectwerkz2.dtd">
<aspectwerkz>
<system id=3D"samples">
<package name=3D"examples">
<aspect class=3D"cflow.Aspect_Tenant1"></aspect>
</package>
</system>
</aspectwerkz>
I set JVM argument as "-javaagent:C:\aspectwerkz-2.0\lib\aspectwerkz-jdk5-=
2.0.jar"
Then I am I try to run the following code :
public class Weaver_Tenant2 {
public static void main(String[] args) {
Target t =3D new Target();
DeploymentHandle handle1 =3D Deployer.deploy(Aspect_Tenant1.cl=
ass);
t.step1();
}
}
RESULT :
AspectWerkz - INFO - Pre-processor org.codehaus.aspectwerkz.transform.Aspec=
tWerkzPreProcessor loaded and initialized
Deployer::INFO - deploying aspect [examples.cflow.Aspect_Tenant2] in class =
loader [sun.misc.Launcher$AppClassLoader@92e78c]
--> invoking step1
--> invoking step2
Here advice is not weaved.
Am I doing any mistake ? or am I missing any settings...?
Please help me to run this...
Thakns lot.
Thanks and Regards,
Kumaravel Ganesan
