HotRod Java client allows execution of remote scripts like JavaScript. There are 4 several internal objects which are exposed as pre-defined bindings while the script is executed. It is also possible to call another Javascript from the Javascript and the pre-defined bindings should be passed to the inner script as well. Unfortunately currently the "cache" and "marshaller" objects are not passed to the inner script. This is a known issue in JBoss Data Grid 7.0.0.Beta To workaround the issue just get the "cache" and "marshaller" objects from the "cacheManager", which is passed properly.
