In normal use within a proxy/ <in> sequence this code, CreateBasicAuthMediator,
works fine when called in a sequence.. From the debug statement the only line
left not executed is, line 66:
map.put("Authorization", "Basic " + (String)Base64.encode(sAuth.getBytes()));
Need to wrap this in try-catch; but I guess there is no map, as no
TRANSPORTHEADER.
I'l catch that too. I will check this.
So no idea why map is null ?
So how do I do a send from this sequence then ? This is my ultimate goal, this
code was removed
from after the java call to simplify the problem example.
What got me was the Quartz Error, before the stack trace. This seems strange
design that I am still in the Quartz task within a new sequence ?
To me the Synapse tasks are still really weird and do not fit in well with
Synapse. The link between sequences, proxies and tasks needs to be at higher
level. However, Low level java tasks are also required. Synapse should be able
to
Schedule proxies and sequences at a higher semantic level, than the "magic"
code used now. These should be not
In the scope of the quartz task. Even in Jeff Davis' book Tasks seem to work by
magic and the underlying mechanism of sending the message, is inexplicable.
Thanks

Subject: Re: Class Mediator Exception after task schedule
Kim,
The logs show a NullPointerException at line 66 in
CreateBasicAuthMediator. Can you please identify the instruction on
that line?
