hi,
I'm implementing a component type for running RESTful workflows (or
compositions - whatever you wanna call it) within SCA. The implementation
worked fine but since I updated to the latest SVN head today it get the
following error message when running it. After some time of debugging I
couldn't really figure out what the problem is.
This is the composite file is like this (the location indicates the
directory where to workflows are stored):)
<component name="FeedAggregatorComponent">
<implementation.splice location="c:/somelocation/" ... " />
</component>
Internally in the implementation calls, I register a service called
SpliceService as JavaInterfaceContract which is the business interface for
talking to my engine. In my test program I have to following:
public static void main(String[] args) throws IOException {
SCADomain scaDomain = SCADomain.newInstance("FeedAggregator.composite"
);
SpliceService spliceService = scaDomain.getService(SpliceService.class,
"FeedAggregatorComponent");
spliceService.performReceive("samples/feeds3/"., "getFeeds",
"sortSample3", "text/plain");
System.in.read();
scaDomain.close();
}
The exception I receive is the following:
