Hi Alejandro,
Compliance 1.6 in Eclipse 3.4.2 should be fine. I just created the
AspectJ Bean example project (File>New>AspectJ Examples>Bean
Example) and changed the compliance to 1.6 and it was ok. What
happens to you when it doesn't work - do you get an error?
I don't have any error, it runs normally but without any output in the
console. I tried it once again but no luck.

If compliance level is 1.5 or above, you will get warnings when
advice does not match - are those the warnings you see? To comment
on why i isn't matching, I would need to see the code - are you able
to post any of it here?
I see the warnings....I also attached the code... as I said is very
simple and is from a book. the warning is in MinimumBalanceRuleAspect.
Thanks a lot for your help, I really appreciated.
Alejandro
public class Account {
private float balance;
private final int accountNumber;
public Account(final int accountNumber) {
this.accountNumber = accountNumber;
}
public void credit(final float credit) {
this.balance = credit + balance;
}
public void debit(final float debit) throws
InsufficientBalanceException{
if(this.balance < debit) {
new InsufficientBalanceException("Not enough money in the
account");
}else {
this.balance -= debit;
}
}
public void setBalance(final float balance) {
this.balance = balance;
}
public float getBalance() {
return balance;
}
}
public final class InsufficientBalanceException extends Exception {
public InsufficientBalanceException(final String mssg) {
super(mssg);
}
}
public final aspect MinimumBalanceRuleAspect {
private float Account.minimumBalance;
public float Account.getAvailableBalance() {
return getBalance() - minimumBalance;
}
after(final Account a) : execution(Account.new(..)) && this(a){
a.minimumBalance = 25;
}
//ADVICE WITH WARNING!!!!!!
before(final Account account, final float amount) throws
InsufficientBalanceException :
execution(* Account.debit()) && this(account) && args(amount){
if(account.getAvailableBalance() < amount) {
throw new InsufficientBalanceException("----- Insufficient funds
-----");
}
}
}
public final class TestAccount {
public static void main(final String[] args) throws
InsufficientBalanceException{
final Account account = new Account(1234);
account.credit(1000);
account.debit(500);
}
}
cheers,
Andy.

Hello I'm Alejandro and also a newbie in this area.
I have the following problems: I've been trying to use Java JRE 1.6
and Compiler compliance level 1.6 in Eclipse 3.4.2 with AspectJ but
it seems not to be working. If I change it to JRE 1.5 and compiler
1.5 works fine.
Is this correct? Could you point me to any place where I can find
this information?
Also, I tried some examples and sometimes I've got that some advices
are not being apply (raised a warning!). I checked it with an
experienced aspect user (not in eclipse) and there is no reason not
to be working (the aspect and the example class are very simple).
Any idea?
Thank you very much in advance for any help,
Alejandro Garcia
