Re: [aspectj-users] How to run compile time weave with ant? Simple case.

Working example:

--- C.java ---
public class C {}
---

Run: ajc C.java -outjar xxx.jar

--- X.aj -- (in aspects subdir)
public aspect X {
before():staticinitialization(C*) {}
}
---


--- build.xml ---
<project default="build">
 <taskdef resource="org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties">
     <classpath>
       <pathelement path="c:/aspectj163-dev/lib/aspectjtools.jar"/>
     </classpath>
 </taskdef>

  <target name="build">
    <iajc srcdir="aspects" inpath="xxx.jar" classpath="yyy.jar;c:/aspectj163-dev/lib/aspectjrt.jar" outjar="xxx_delta.jar" showWeaveInfo="true">
    </iajc>

  </target>
</project>
---

Run: ant
Buildfile: build.xml

build:
     [iajc] weaveinfo Join point 'staticinitialization(void C.<clinit>())' in Type 'C' (C.java) advised by before advice from 'X' (X.aj:2)

BUILD SUCCESSFUL

It means in order for the weaver to do what you asked, it needed to weave ServiceUnit and because you only gave it to the compiler on the classpath rather than something it could operate upon (via the inpath) then it could not weave it because it couldn't see it.

I have an aspect

public aspect FilterAspect {

in file FilterAspect.aj

How do i run iajc "ant" task to weave jar xxx.jar that depends on jar yyy.jar and place into file xxx_delta.jar

I know how to do LTW but can't get compile time weave to work.


In my attempts i saw this

     [iajc] warning at (no source information available)
     [iajc] C:\workspace\new\EnterpriseManager\gui\esbConsole\lib\jbi\jbi_rt.jar:0::0 this affected type is not exposed to the weaver: com.sun.jbi.framework.ServiceUnitFramework [Xlint:typeNotExposedToWeaver]
     [iajc] warning at (no source information available)
     [iajc] C:\workspace\new\EnterpriseManager\gui\esbConsole\lib\jbi\jbi_rt.jar:0::0 this affected type is not exposed to the weaver: com.sun.jbi.framework.ServiceUnit [Xlint:typeNotExposedToWeaver]

What does it mean?


I'd like to do something as simple as

<iajc inJar="xxx.jar" classpath="yyy.jar;aspectrt.jar" aspect="FilterAspect.aj" outJar="xxx_delta.jar"/>


I have to ask why is this so hard? I don't get all the options. A few more examples would be awsome.


Thanks much.

Assuming this is a classloading issue, how does one write an aspect using LTW where the aspect is brought into memory before the actual impl jars are?

I had been intercepting objects in the jar file containing com.sun.jbi.framework with other pointcuts but hadn't been referencing specific classes before.

Now that i have to reference specific classes it is no longer working.


import com.sun.jbi.framework.ServiceUnit;
import com.sun.jbi.framework.ServiceUnitFramework;

public aspect FilterAspect {
...
    public pointcut startServiceUnitJoinPoint(
        ServiceUnitFramework framework,
        Component component,
        ServiceUnitManager manager,
        ServiceUnit unit) :
       
        withinFramework() &&       
        execution(private void startServiceUnit(Component, ServiceUnitManager, ServiceUnit)) &&
        this(framework) &&
        args(component, manager, unit);


Can i change ServiceUnit and ServiceUnitFramework above to Object or something more general so i don't reference them at the time the aspect is loaded? What is best practice here? Note this is occuring in an app server.
