Re: [aspectj-users] flow of execution in different threads
|
Valerio,
Since I was creating a regression testing system I could enforce some
assumptions. I had to use the following method, because the
oh-so-nice-and-wonderful IBMJDK 1.3 (Websphere 4) pukes on static
introduction. I only allowed one overall thread of execution to function
at a time. In the system I tested this meant only one call to the
Websphere server at a time. Then I passed context information from one
thread to the next with a singleton (actually, anything that both threads
can reach will work). Not elegant, but it got the job done.
If you can use static introduction, you have a better alternative. You use
static introduction to attach context information to the argument objects
that get passed from one thread to another. This way you can pass any
information you want across thread borders. Your could for instance
generate a unique number per cflow, and pass that along with your
arguments using static introduction. This solution is very close to the
wormhole pattern that you can find in Laddad's AspectJ in Action.
Grtz,
Serge.
