Hi,
I was trying to add an interface introduction to a class during runtime, i.e.
by dynamic AOP, but so far without success.
I was able to do it by "static" AOP, i.e. adding the respective tags in the xml
files as described in the reference manual or the tutorial.
The important excerpt from my (static) xml-file:
<introduction class="MainClass">
| <mixin>
| <interfaces>
| Printable
| </interfaces>
| <class>Printer</class>
| <construction>new Printer(this)</construction>
| </mixin>
| </introduction>
Intending to use dynamic AOP, I tried it with the following:
MainClass myMainClass = new MainClass();
| String[] interfaces = {"Printable"};
| // use InterfaceIntroduction-Constructor found in the API for
jboss-aop_1.5.3.GA
| InterfaceIntroduction ii = new
InterfaceIntroduction("SomeArbitraryName","MainClass", interfaces, "Printer",
"new Printer(this)");
| AspectManager.instance().addInterfaceIntroduction(ii);
|
| // use reflection to invoke the method "print" which is implemented by
Printer.
| // this worked using "static" AOP. However it throws an exception now.
Therefore
| // something must have gone wrong :-(
| try {
| myMainClass.getClass().getMethod("print", null).invoke(myMainClass,
null);
| } catch (Exception e) {
| e.printStackTrace();
| }
I don't know whether I have to prepare anything for my issue, but I tried both
without and with the following: <prepare expr="all(MainClass)"/>
I tried both running in loadtime mode as well as in HotSwap-mode.
Any ideas what I made wrong? Is it possible at all to add an interface
introduction using Dynamic AOP?
Thanks in advance for your help!
Hannes
