Struggling with how to make a simple poincut [message #543264]

I would like for some code to be called after a certain JButton is created, in this case:

JButton commitButton = new JButton("Commit");

When that button is called, I would like to insert some lines of code right after that. I can do that based on it being a JButton or based on the fact that it is a JButton and the arg is "Commit" right?

Here is what I have so far, but it is syntactically incorrect. Any suggestions?

public aspect HelloAspect {
after() : call("new JButton("Commit")") && !within(HelloAspect)
{
System.out.println("Commit button constructed");
}
}

Also, I am kinda struggling with the AOP lingo, so correct me if I am wrong, but I am asking for help on how to write my pointcut on a JButton initialization join point?

I got it

after(String s) : call(javax.swing.JButton.new(String))
&& args(s)
&& if(s.equals("Commit"))
&& !within(HelloAspect)
{
System.out.println("Commit button constructed");
}
