Hi Daniel
Disregarding the multiple bindings angle for a moment. For a single remote
binding, looking at you composite I think the reference side should look
like....
<reference name="crawlers" multiplicity="1..n"
target="CrawlerComponent SpecialCrawlerComponent">
<binding.ws/>
</reference>
And the service side should be as you have it, e.g.
<service name="Crawler">
<interface.java interface="interfaces.Crawler"/>
<binding.ws uri="
http://AFA-19393:8088/CrawlerComponent<http://afa-19393:8088/CrawlerComponent>"
/>
</service>
etc.
Does that work?
