Hi Krishna.
You mean catch, not cache. What you can do is intercept the method which is actually throwing the exception if it is accessible/weavable for you. I.e. if that joinpoint is in an external library, you need to weave the library. If it is in the JRE, you need to weave the JRE. That way you could also intercept the creation of exceptions by targetting their constructors. -- Alexander
Thanks Andy for clarification.
My confusion is on how to handle the
cache exception such as follows.
If the cache block throws exception
i can use a handler on get the exception.
cache(Exception e){
throw e;
}
Where as if the developer just did like
below, handler cannot caught it. How to proceed in this case.
cache(Exception e){
log.error("Exception occured");
}
Thanks,
Krishna
There is no joinpoint for array access
so you cannot catch the exception unfortunately.
Some form of support could be added
to AspectJ, but is not currently on the radar.
cheers,
Andy

Hi ,
Can anybody faced a similar situation like this.
How to specify a pointcut and advice for caching this type of exception.
try{
int array[]={10,20,30};
System.out.println("The value of array is" +array[5]);
}
catch(ArrayIndexOutOfBoundsException
aiob){
aiob.printStackTrace();
}
Thanks,
Krishna
