The second use case is simply a programmatic service or API that you wish to expose. Macros are not supposed to return anything. To implement your second use case you'd create a Script Service component in java, see http://extensions.xwiki.org/xwiki/bin/view/Extension/Script+Module Now there's another possibility which is to: * call your macro using a groovy script. You'll need to look it up and call its execute method. This will return a List of Blocks * still in the groovy macro code, lookup a renderer and tell it to render the list of blocks. This is slightly more tricky and I don't see why you'd want to do this TBH. To help you further we'd need to know more about your specific use case. ----- But I just understood that you simply want to render the macro from inside your velocity script. So you'd just need to do this: {{velocity}} #set($words = ["Some", "velocity", "code"]) #foreach($word in $words)   $word ##   {{mymacro param="$word"/}} #end {{/velocity}} Hope it helps, -Vincent
