Axis2SCAReferenceBindingProvider throws exception if servlet host not present
-----------------------------------------------------------------------------
Key: TUSCANY-3540
URL: https://issues.apache.org/jira/browse/TUSCANY-3540
Project: Tuscany
Issue Type: Bug
Components: Java SCA Misc Binding Extensions
Reporter: Simon Nash
Assignee: Simon Nash
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.
