Spring Hessian Exception

Question

Im looking into handling recovery from Spring Hessian connection being down. What are the exceptions possible that hessian proxy can throw if the connection is down?

Answer 1

Here is a sample stack trace that you'll get every time you’ll try to connect to a hessian remote service which is unavailable:

Exception in thread "AWT-EventQueue-0" org.springframework.remoting.RemoteConnectFailureException: Cannot connect to Hessian remote service at [http://localhost:17026/remoting/TestService]; nested exception is java.net.ConnectException: Connection refused: connect at org.springframework.remoting.caucho.HessianClientInterceptor.convertHessianAccessException(HessianClientInterceptor.java:262) at org.springframework.remoting.caucho.HessianClientInterceptor.invoke(HessianClientInterceptor.java:235) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:172) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:202) at $Proxy1.getNameFromKassa(Unknown Source) …

BTW, the hessian proxy won't throw you any exception for the simple reason of being down ;)
