Hello AOP-Experts,

I have some code using threads like this:

public void run() {
  try {
    while (true) {
       /* some code */
       Thread.sleep( 2000 );
    }
  } catch ( InterruptedException e ) { e.printStackTrace(); }
}

Now I would like to know how much time it tooks from the moment a thread wakes up to the moment it goes sleeping again.
My problem is that I can't easily match on /* some code */ because it is not a simple function call. All code whose execution time I want to measure is included in the run method.

Can I formulate an adequate pointcut for this?

Can anyone help to fix this problem, please?

Thanks in advance,

Andreas

Hi,

I was preprocessing the OracleDriver (oracle.jdbc.driver.OracleDriver) using aspectwerkz and it failed while preprocessing. I got the following error.

I did some research and found that if oraclepki.jar which has the OracleWallet class is not in the classpath, we get this error. If I add that to the classpath along with ojdbc14.jar, we do not get this error. However the oraclepki.jar is not mandatory for oracle driver to work, so aspectwerkz preprocessor should be able to preprocess the OracleDriver even if oraclepki.jar is not in classpath.

I tried to look through the source code and saw that even if we fail to obtain a dependent class as stream, we still call new ASMClassInfo(stream) on it which causes this exception and hence complete preprocessing fails. I looked at the CVS repository and see that there has been some change in version 1.15 of AsmClassInfo which probably resulted in this. (http://cvs.aspectwerkz.codehaus.org/browse/aspectwerkz/aspectwerkz4/src/main/org/codehaus/aspectwerkz/reflect/impl/asm/AsmClassInfo.java?r1=1.14&r2=1.15)

if (componentClassAsStream == null) {
                // might be more than one dimension
                if (componentName.indexOf('[') > 0) {
                    return getClassInfo(componentName, loader);
                }
                System.out.println(
                        "AW::WARNING - could not load class ["
                        + componentName
                        + "] as a resource in loader ["
                        + loader
                        + "]"
                );
                componentInfo = new ClassInfo.NullClassInfo();
            }
//The 1.14 version returned the ClassInfo.NullClassInfo() if componentClassAsStream was null and did not proceed further
            try {
                componentInfo = AsmClassInfo.getClassInfo(componentClassAsStream, loader, lazyAttributes);
            } finally {
                try {
                    componentClassAsStream.close();
                } catch (Exception e) {
                    ;
                }
            }


Any help with this will be greatly appreciated

Thanks Much
Amit

Hello,
 
In the below scenario,  Once I run the client, the aop.xml gets recognsied by -Daspectwerkz.definition.file=path/aop.xml but the application is not getting pointcut.  Any clues why ?
Thanks and Regards,
Lalithamba.

Hi,
 
I am using Aspectwerkz to pointcut a standalone CORBA application which is running under naming service TAO in LINUX.
 
I have the following files :
 
Hello.idl
HelloClient.java
HelloServer.java
 
 
Now I execute the idl file using idlj utility of Java as follows : 
==============================================
idlj -fall Hello.idl (this creates the stubs)
 
Compile the Client and Server file : 
========================
javac HelloClient.java HelloApp/*.java
javac HelloServer.java HelloApp/*.java
 
set ASPECTWERKZ_HOME=D:\aspectwerkz-2.0

======================================================================
 
Now the naming service is running on linux.
 
I run HelloServer as follows : 
 
java -Xbootclasspath/p:.:/opt/ALNA/bin/avalon-framework-4.1.5.jar:/opt/ALNA/bin/jacorb.jar:/opt/ALNA/bin/logkit-1.2.jar: -DORBInitRef.NameService=corbaloc:iiop:10.116.69.123:23000/NameService HelloServer
 
This shows : HelloServer ready and waiting ...
 
Next I am running HelloClient using aspectwerkz as :
 
/opt/aspectwerkz/bin/aspectwerkz -javaagent:/opt/eprofiler/Hello/eProfiler.jar -cp /opt/eprofiler/Hello/eProfiler.jar:/opt/eprofiler/Hello/aopfile.jar -Xbootclasspath/p:.:/opt/eprofiler/Hello/aopfile.jar:/opt/eprofiler/Hello:/opt/eprofiler/Hello/eProfiler.jar:/opt/ALNA/bin/avalon-framework-4.1.5.jar:/opt/ALNA/bin/jacorb.jar:/opt/ALNA/bin/logkit-1.2.jar:/opt/aspectwerkz/lib/aspectwerkz-core-2.0.jar:/opt/aspectwerkz/lib/aspectwerkz-2.0.jar: -DORBInitRef.NameService=corbaloc:iiop:10.116.69.123:23000/NameService HelloClient
 
After I run this, the application is not getting cross-cut.  Only the SOP of the program is getting printed.  My thought is aop.xml is not getting recognised.
aop.xml is present in META-INF directory and also I have placed it in aopfile.jar which just has META-INF directory with aop.xml file in it.  
 
Any help in recognising the aop.xml is appreciated.
 
Thanks in advance.

I am using websphere portal server 6.0. I am putting all aspectwerkz jar
files in ws.ext.dirs class path. but these jar files are not recognised, is
it because of aop.xml or any otherway so that i can put all these jar files
in classpath. I am getting the error shown below. 

org.codehaus.aspectwerkz.aspect.management.NoAspectBoundException:
NoAspectBound: NoAspectBound: Could not find AspectDefinition -
samples/com.wipro.eprofile.aspect.metrics.aspect.WebTierAspect 

Please let me know how I should add these files in websphere portal server.

Thanks in advance.

Shylaja.

Hi!

I have two aspects (A1 and A2) which both derive from a base class. Is it
possible to define these aspects in a way that depending on the calling
class A1 or A2 is used? I tried several things in the pointcut definition
but always the first aspect mentioned in the aop.xml file gets used... 

So for beeing in class "myotherpackage.Sample_AOPConfiguration" I want to
use aspect "A1" and for the the second class
"myotheroackage.TestCase_AOPConfiguration" I want to use "A2". Consider this
like an attempt to use a different aspect implementation in testing/mocking
than production or something similar.

My "aop.xml"


<aspectwerkz>
    <system id="MySystem">
        <package name="mypackage">
            <aspect class="A1">
                <pointcut name="pcn1"
                         
expression="within(myotherpackage.Sample_AOPConfiguration) and
                          execution(@mypackage.MyInject mypackage.ResultData
*.*.get(..))"/>
            </aspect>

            <aspect class="A2">
                <pointcut name="pcn2"
expression="within(myotherpackage.TestCase_AOPConfiguration) and
                          execution(@mypackage.MyInject myPackage.ResultData
*.*.get(..))"/>
            </aspect>
        </package>
    </system>
</aspectwerkz>


Thanks in advance

Dmitry Negoda commented on AW-478:
----------------------------------

The patch turned out to be wrong. All we need is to use ReferenceIdentityMap from commons-collections. The m_perInstance should be declared as:

    protected final Map m_perInstance = new ReferenceIdentityMap(ReferenceIdentityMap.WEAK, ReferenceIdentityMap.HARD);

> When using perInstance aspects and calling aspectOf inside an advise, it calls hashCode() on the instance, which may cause recursive calls to an aspect. AOP should not call any of the instance methods to avoid side-effects. The following AbstractAspectContainer.aspectOf(instance) implementation fixes the problem:

>     	Ref ref = new Ref(instance);

             Project: AspectWerkz
          Issue Type: Bug
          Components: core
    Affects Versions: 2.0
         Environment: Java 1.5
            Reporter: Dmitry Negoda


When using perInstance aspects and calling aspectOf inside an advise, it calls hashCode() on the instance, which may cause recursive calls to an aspect. AOP should not call any of the instance methods to avoid side-effects. The following AbstractAspectContainer.aspectOf(instance) implementation fixes the problem:

    public Object aspectOf(final Object instance) {
    	Ref ref = new Ref(instance);
        synchronized (m_perInstance) {
            if (!m_perInstance.containsKey(ref)) {
                m_perInstance.put(ref, createAspect());
            }
        }
        return m_perInstance.get(ref);
    }

    static class Ref {
        Object object;
        int hash;
        public int hashCode() { return hash; }
        public boolean equals(Object object) {
            if (object instanceof Ref) {
                return ((Ref)object).object == object;
            } else {
                return false;
            }
        }
        Ref(Object object) {
        	this.object = object;
        	hash = System.identityHashCode(object);
        }
    }

Alex,
  I would like to know, what would be the right approach to bring the parallel execution of advice functionality up in the solution. 
  Should I tweak the framework code or own solution (means create a thread in advice and execute localize concerns code in run method)?
   
  Code snippet to add in own solution---
   
  MyAdvice() 
  {
       MyConcerns concerns = MyConcerns ();
       new Thread(concerns).start();
  } 
   
   
   
  ------------------
  Class MyConcerns ()
  {
     public void run()
    {
      System.out.println("Log info");
    }
  }
   
  -----------------------------------
   
  Note - If we need to tweak in the framework code then where I need to do. Please do let me know.
   
  Thanks
Akhilesh

  Alex,
  I have some doubt.  Because, attached document section 5, 6 and 7 describes that AOP advice run in parallel with the application code. 
   
  In this url http://www.sdtimes.com/editorial/opinion-20020101-01.html article explain in the same line.
   
  Still, my understanding is not clarified, because your reply defer from the article. 
   
  Is that all Java AOP framework inherently not support parallel execution of advice with the application code?
   
  Please let me know.
   
  Thanks

Hi All,
  Is this the only mechanism to run advice in parallel with the
application methods for that cross cut defines?
  Or, any other option comes inherently with AOP framework to do the same.  Please do let me know.
   
   
  Thanks
  Akhilesh

  Hi All,
  I would like to get clarify my self about AOP advice execution sequence along with the application code. Does AOP advice execute in parallel with application methods for that cross cut defines?
   
  For example 
  Application method - foo()  (for cross cut define)
  Takes execution time T1
  Advice – fooAdvice() takes t1 time
   
  If AOP advice runs sequentially with application code then additional performance hit because of advice code execution. 
   
  Total time will be – T1 +t1
   
  From my understanding it runs in parallel therefore it takes time equal to whichever is higher for ex – T1
   
  Please correct my understanding
   
  Thanks
  Akhilesh

Thx for the reply, in the end I got it working by changing the
deployment-model to perJVM. 

 

No Instance of com.xxx.core.audit.Log is ever created (it's a static
singleton ) so maybe the aspect could never get bind wih the perinstance
setting?

Just a guess on my part..

Here is the working xml snippet

 

       <!-- Aspect to capture username in trxns-->
     <aspect class="GetUserAspect" deployment-model="perInstance">
           <pointcut name="SetUser" expression="execution(* void
com.xxx.core.audit.Log.setUser(..))"/>
           <advice name="storeUserName(StaticJoinPoint jp)" type="after
returning" bind-to="SetUser"/>     </aspect>

an "after returning" joinpoint kind on a "void method(stuff)" will likely
not match

use simply after perhaps

Yes it is possible, but you will have to define a so-called
'deployment scope' and preweave the classes (will just add tiny hooks,
but no aspects). Then you can do hot deploy and undeploy in a running
system.
Details here: http://aspectwerkz.codehaus.org/new_features_in_2_0.html#Hot_deployment_and_undeployment_of_aspects

Does AspectWerkz support the remote weaving? Let me explain my scenario in
detail.
Suppose there is a running Java application. It don't know AspectWerkz. I
want to insert an aspect into the running application. This is called the
remote weaving. Is there any way to weave already running Java classes?
