Remote Service through Hessian

Hi all,

 

I'm trying to expose a service through Burlap, which works fine. Now, I want to change it to Hessian, so I say: static expose = ['hessian'], instead of Burlap.

 

This doesn't work. When starting up the application (with Java 5 on Windows XP), I'm getting this stacktrace:

Spring supported debug support for Hessian, but this breaks the Remoting plugin, since HessianDebugOutputStream is not available in Hessian 3.1.1 (the currently used version). It is available in Hessian 3.1.3, so I guess upgrading the plugin to the newer version should fix this problem!

My guess is you need the hessian jars in your lib

Cheers

Hi Graeme,

The Hessian jars are already in the plugin, so they are in the classpath.
The problem is that the version is to old: it needs to be upgraded to 3.1.3
instead of 3.1.1.

Please raise an issue against the Remoting plugin. In the meantime,
you can simply replace the JAR file inside the installed plugin.

Thanks,
