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

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

Jens

yes you can code for that, but the AOP framework won't create any thread for you
those papers are about use case, and not about framework features

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

no it runs in the same code path - as if you wrote it
this said it is easy to have your advice produce an async task that
will be consumed by some thread queue if you want
it is all up to you

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.

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?

DK

a UnsatisfiedLinkError usually means a .dll or .so is not in the path /
classpath
(please check but I believe the folder has to be in PATH, possibli
LD_PRELOAD and not the .dll/.so itself ie this is NOT like jar files in
classpath)
