Tutorials

Hello,

I'm not sure how to write the authors so I'll put a comment here and hope someone sees it.

Referring to the HelloWorld example I noticed that the second method "greet" is of type String but does not have a return statement in the execution part. I added that and the code compiled fine.

Also the command, in the tutorial, to recompile HelloWorld with AspectWorksz 2.0 is

javac -d target -classpath $ASPECTWERKZ_HOME/lib/aspectwerkz-2.0.RC1.jar MyAspect.java

I could not get this to work because the zip file does not contain aspectwerkz-2.0.RC1.jar. I tried many of the other jar files but I kept getting the following:

C:\testAOP>javac -d target -classpath $ASPECTWERKZ_HOME/lib/aspectwerkz-2.0.RC1.
jar MyAspect.java
MyAspect.java:3: package org.codehaus.aspectwerkz.joinpoint does not exist
import org.codehaus.aspectwerkz.joinpoint.JoinPoint;
^
MyAspect.java:7: cannot resolve symbol
symbol : class JoinPoint
location: class testAOP.MyAspect
public void beforeGreeting(JoinPoint joinPoint) {
^
MyAspect.java:11: cannot resolve symbol
symbol : class JoinPoint
location: class testAOP.MyAspect
public void afterGreeting(JoinPoint joinPoint) {
^
3 errors

I hope someone can advise and fix the problems in this example.

Hello,

I'am trying to build the first simple example but keep getting complains about org/xml/sax/EntityResolver that could not be found. I'v been on this al day now and tried every jdk / xml lib etc. It propbably has got to do with my configuration but it is driving me nuts so every suggestion is highly appreciated , i cannot wait to start with AOP.

Thanks upfront,
Dennis

you have to do this operations to solve the problem:

1) C:\aspectwerkz-2.0\bin>edit aspectwerkz.bat

2) insert this strings after the istruction @ECHO OFF

set aspectwerkz_version=2.0
set aspectwerkz_home=c:\aspectwerkz-2.0
set java_home=c:\programmi\java\jre1.5.0\lib\ext\qtjava.zip

hi 

I want to weave my advice before and after  public methods of public class. I tried using execution  AND within pointcut() together to limit the scope...

The XML is used is

<aspectwerkz>
    <system id="AspectWerkzExample1">
           <aspect class="expressionTesting.ExpressionAspect">
                <pointcut name="greetMethod" expression="within(public expressionTesting.*) AND execution(public * *(..)) "/>
                <advice name="beforeGreeting" type="before" bind-to="greetMethod"/>
                <advice name="afterGreeting" type="after" bind-to="greetMethod"/>
            </aspect>
      
    </system>
</aspectwerkz>

note

expressionTesting is the name of the package

but this doesn't work out ...

seems there is some problem with the expression ....help me to get the correct expression

reply asap...
