How do I find which Java version is being used to

问题:

I am executing my rules on the Business Rules service on Bluemix, and want to know which Java runtime version is used. How do I find this information?

回答1:

This information is available if I enable tracing for the payload, for example by invoking it using https://brsv2-instanceID.domain/DecisionService/run.jsp?path=/ruleApp/1.0/ruleset/1.0&trace=true

(for example: https://brsv2-12345678.ng.bluemix.net/DecisionService/run.jsp?path=/myRuleApp/1.0/myRules/1.0&trace=true)

I made sure that infoSystemProperties was set to true for JSON.

The trace after execution of the request contains a "systemProperties" element/entry, which includes the Java information.

The answer How can I trace rules in the Business Rules service on Bluemix? has more information on tracing.
