Re: How to generate the output for a given java collection object

    Have you tried without removing the parenthesis? I'm just guessing...

   [#list (itemMap?keys) as key]
       ${key} [#list (itemMap[key]) as item]${item}[/#list]
    [/#list]

Or
 
   [#assign keys = itemMap?keys /]
   [#list keys as key][#assign items = itemMap[key] /]
       ${key} [#list items as item]${item}[/#list]
    [/#list]

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
