[aspectj-users] How to wrap an unchecked exception in a business uncheck

[Dmitri Mamrukov <dym@xxxxxxx>]

Greetings!

A business application may have methods like this:

   public void doSomething() throws BusinessException
   {
      try
       {
         doLogic();
       }
       catch (Exception e)
       {
           throw new BusinessException(e.getMessage());
       }
   }

That is, any checked exception thrown is wrapped with an unchecked 
business exception. So I'd like to aspectize this concern. I've tried 
this advice (I've read articles that suggest this way):

   Object around() throws BusinessException : operations()
   {
       try
       {
           return proceed();
       }
       catch (Exception e)
       {
           throw new BusinessException(e.getMessage());
       }
   }

And modified the above business method:

   public void doSomething() throws BusinessException
   {
      doLogic();
   }

However, this does not work since the compiler complains about unhandled 
checked exceptions.

I've also tried

   declare soft: Exception : operations();

but this wraps checked exceptions in unchecked (run-time) exceptions.

Thanks,
Dmitri
