HTTP Binding is failing to start due to inimplemented function being called by
toString()
-----------------------------------------------------------------------------------------
Key: TUSCANY-3766
URL: https://issues.apache.org/jira/browse/TUSCANY-3766
Project: Tuscany
Issue Type: Bug
Components: Java SCA HTTP Binding
Affects Versions: Java-SCA-1.6
Environment: Tuscany Java SCA 1.6
Windows XP SP3
JDK 1.6
Reporter: Padraig Myers
Attachments: 3766.padraigmyers.patch
I set up a service using Tuscany that exposes itself using binding.http.
This service is implemented using Spring and will act like a servlet to all
intents and purposes.
However during startup an exception is thrown because the method
org.apache.tuscany.sca.implementation.spring.invocation.SpringImplementationTie
.getURI() is being called, and this method has nothing in it but "throw new
IllegalStateException("Not yet impl");"
However in the scenario above the only reason that getURI() us being called is
because of a toString() that gets run on startup.
By changing getURI() to:
public String getURI() {
return this.component.getURI();
}
the exception is not thrown and no other problems occur and our service works
perfectly. (patch attached)
The solution here is either the code above, however this may have knock on
effects on other components that use getURI() there throwing an exception is
OK, however in this case because it is only being called in a toString() either
we should not throw an exception, or else the toString() should catch and
swallow the exception.
Here is the trace of the exception that happens:
