Re: [Resin-interest] Updating Hessian in Resin 4.0 deployments
Hessian was extracted to a separate hessian.jar in the Resin dist a while back, which made it possible to upgrade Hessian without changing Resin version. For some reason hessian was moved back into resin.jar. /Mattias Scott Ferguson wrote (2009-06-18 00:16): On Jun 17, 2009, at 2:10 PM, Rick Mann wrote: On Jun 17, 2009, at 13:58:29, Scott Ferguson wrote: On Jun 17, 2009, at 1:48 PM, Rick Mann wrote: If I download/build a separate Hessian library and drop it into my WEB- INF/lib directory, will it get used instead of the one built-in to Resin? No, you need to put the replacement in the CLASSPATH (so it's loaded before the resin.jar). In Java, the parent classloaders have priority (that order is needed because of class cast issues.) So any hessian in WEB-INF/lib would be ignored. Hmm. I've always tried to steer far clear of putting anything on the CLASSPATH when running servlet containers. I don't know if I learned that back when I used Tomcat, or if it was something Resin recommended. Well, it's normally not a good idea, but it's how you would override hessian. A better alternative would be for me to get to a place where I build resin and run my build; this would allow me to insert logging to help me figure out problems when I run into them all across resin, let alone just Hessian. But Hessian is my most urgent need right now. Are there instructions for building Resin anywhere? You should be able to just download the source and use ant. I think we cleared up the dependencies (with the exception of 'ant dist'). -- Scott -- /Mattias ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest

For some reason hessian was moved back into resin.jar. Because having only two jars is more convenient for most people, and anyone sophisticated enough to want to change hessian is sophisticated enough to put it in front of resin.jar in the classpath. -- Scott /Mattias Scott Ferguson wrote (2009-06-18 00:16): On Jun 17, 2009, at 2:10 PM, Rick Mann wrote: On Jun 17, 2009, at 13:58:29, Scott Ferguson wrote: On Jun 17, 2009, at 1:48 PM, Rick Mann wrote: If I download/build a separate Hessian library and drop it into my WEB- INF/lib directory, will it get used instead of the one built-in to Resin?

[Resin-interest] Updating Hessian in Resin 4.0 deployments
If I download/build a separate Hessian library and drop it into my WEB- INF/lib directory, will it get used instead of the one built-in to Resin? TIA, -- Rick ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
