unable to open input stream for resource *.class in archive *.war
12,122
I had compiled with Java 8 and was running on Websphere Java 7.
I am using gradle as my build tool, and by default it uses the underlying JVM to compile java sources. Being JDK 1.8.0_11, this was the reason my classes could not be opened at runtime.
I feel very silly.

I am attempting to start up a simple spring-mvc web app.
I have a DispatcherServlet mapped to
/api/*and a@RestControllerwithGETmethods mapped to/test1.I have encountered this error (when i hit the url:
'http://myserver/api/test1') that no-one in the google-sphere seems to know about:[31/07/14 12:48:32:383 EST] 00000088 ecs W com.ibm.ws.ecs.internal.scan.context.impl.ScannerContextImpl scanClassesDir

when i hit the url
'http://myserver'Any ideas why my classes are unable to be opened?
