[esb-java-user] How to use Axis client in a class mediator

[Arjan Visser]

A callout mediator works for just 1 call. I need to do a number of calls in
sequence. Also iterator does not work because it processes all calls in
parallel. What I need is a serial iterator.

 

For every <article> in <articles> I need to do a SOAP call in sequence. How
to implement this in the bus?

Try using callout mediator.

Hi,

 

I have to use Axis2 client in a class mediator for calling an external
webservice. This call has to be a blocking call. When I use this client in
the class mediator, I get the following error:

What is the right way to use a blocking SOAP call in a mediator? Using the
same class mediator in a standalone Java projects works fine (using the
Axis2 libraries packed with WSO2).

 

Used version : 2.1.2
