> Key: TUSCANY-3540
> URL: https://issues.apache.org/jira/browse/TUSCANY-3540
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Misc Binding Extensions
> Affects Versions: Java-SCA-1.6
> Reporter: Simon Nash
> Assignee: Simon Nash
> Fix For: Java-SCA-Next

>
> When using the distributed SCA binding on a reference, the code in
> Axis2SCAReferenceBindingProvider throws an exception if no servlet host is
> present, even though a servlet host is not required or used in this scenario.
> Here's the stack trace:
> Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0,
> Size: 0

> The problem is caused by the following line in the constructor for
> Axis2SCAReferenceBindingProvider:
> ServletHost servletHost = servletHosts.getServletHosts().get(0);
> This sets a local variable servletHost which is not used anywhere, but throws
> an exception if a servlet host isn't present. It appears that this line has
> been incorrectly copied from Axis2SCAServiceBindingProvider, which does need
> a servlet host. To avoid this exception the user has to configure an
> unnecessary servlet host. The fix for the problem is simply to remove the
> above line.
