Hello there, the classes RmiClientInterceptor and RmiProxyFactoryBean that fzhong has mentioned as a model implementation are both parts of Spring. In particular, the invoke method is in the RmiClientInterceptor.
Both classes sit in package org.springframework.remoting.rmi in jar org.springframework.context-sources-3.1.0.M1.jar of the Spring framework source distribution. -- Sebastian > -----Original Message----- > From: ant elder [mailto:ant.el...@gmail.com] > Sent: Thursday, March 17, 2011 12:17 PM > To: user@tuscany.apache.org > Subject: Re: Tuscany 1.6 RMI bug: ConnectException after component > restart > > I'm having some trouble finding where that code is you're suggesting > to change, where is that invoke method - is it a Tuscany class or a > Spring - what is the class and package name? > > ...ant > > On Wed, Mar 16, 2011 at 1:44 AM, fzhong <fzh...@travelsky.com> wrote: > > Hi all, > > I had encountered this problem,In fact,the implementation of RMI > references > > is simple,it lacked the capacity to respond to some exception.The > Spring rmi > > client is a good > > job(org\springframework\remoting\rmi\RmiProxyFactoryBean,you can find > more > > details in class RmiClientInterceptor),it provides a > > refreshStubOnConnectFailure property,that indicate > > whether to refresh the RMI stub on connect failure.
