Re: [aspectj-users] Unable to access new ITD in a successfully woven rt

[Michael McCray <mike@xxxxxxxxxxxxxxxxx>]

I think you need to try:
javac -Xbootclasspath/p:woven-rt.jar Main.java
you need to add /p to say "prepend.
also, you might need to add aspectjrt.jar as well for certain things:
javac -Xbootclasspath/p:woven-rt.jar;aspectjrt.jar Main.java

Hi all,

I'm adding ITD to rt.jar and so far I've weaved rt.jar successfully.
But, for some reason I'm not able to access the new ITD from my woven-rt.jar.
I've done my homework (6-hour googling to find some hints), but no luck.
So, I'd deeply appreciate if I can get any help here.

Here's my simple aspect, where I just want to add "String test" to the
claas java.io.File:

  package mytest;
  public interface ClassWC { };
  public aspect weavert {
    declare parents: File implements ClassWC;
    public String ClassWC.test;
  }

I compiled that, and ran javap on my woven-rt.jar:

  javap java.io.File -bootclasspath woven-rt.jar

I get this:

  public class java.io.File
    extends java.lang.Object
    implements java.io.Serializable,
               java.lang.Comparable,
               mytest.ClassWC {
    ...
    public java.lang.String ajc$interField$mytest_weavert$mytest_ClassWC$test;
    ...
 }

So up to this point, everything seems okay.
Now, here's my simple test program (Main.java) where I just want to
see if File.test is accessible or not.

  main() {
    File f = new File("file.txt");
    String test = f.test;   
  }

I compiled that:

  javac -Xbootclasspath:woven-rt.jar Main.java

I get this following error:

  Main.java:21: cannot find symbol
  symbol  : variable test
  location: class java.io.File
            String test = f.test;


I totally have no clue why I cannot access File.test.
I try to make the original rt.jar unreadable (chmod 000)
to verify that javac is not reading the original rt.jar.
It turns out I get this error:

  java/lang/ClassNotFoundException: error in opening JAR file <Permission denied>


I believe I use bootclasspath properly.
Please help me point where I did wrong.
Thanks again for your time!

Harry
