can't help you directly, but there seems to be a book on it: www.amazon.com/exec/obido...638-1512167

sadly, given the bleeding-edge nature of the thing and the Java world's obsession with Ant, it's worth being open to the possibility that there's no way to use AspectJ without Ant, or that doing so will take a lot of work.

Hey

I'm looking into AspectJ as well and have a question - What is the difference between a Concern and an Aspect? Is an Aspect just an implementation of a Concern?

Thanks

I just wrapped up a talk on AOP, so thought I'd post my example. From what I've seen, I don't think you *need* Ant for this, but it will definitely help.

Anyway, let's take two classes, Logger, OrderProcessesor. Very simple:

public class Logger
{
public static void log(String msg)
{
System.out.println(new java.util.Date()+" - "+msg);
}
}

public class OrderProcessor
{
public static void processOrder(String productID, int quantity) throws Exception
{
System.out.println("Product ID "+productID+" ordered");
}

public static void main(String[] args) throws Exception
{
for (int i = 0; i < args.length; i++)
{
OrderProcessor.processOrder(args[i], 1);
}
}
}

Now let's take a simple crosscut: log before and after each method. Let's write the aspect for it.

public aspect OrderProcessingAspect
{
pointcut callProcessing() : call(public static void OrderProcesser.process*(..));

before() : callProcessing()
{
Logger.log("starting method");
}

after() : callProcessing()
{
Logger.log("Ending method");
}
}

Then compile using "ajc" and run the OrderProcessor as normal. One snafu I ran into was during compilation. In order for the weaving to work properly, all files must be given to ajc at once. Maybe that's where you ran into problems.
