Can you do something like this in a velocity template?
#set ($map = $myobject.getMap() ) #foreach ($mapEntry in $map.entrySet()) <name>$mapEntry.key()</name> <value>$mapEntry.value()</value> #end it outputs blank tags like so:
<name></name> and
<value></value> What am I doing wrong?

Use the forEach() method to iterate over a Map object. The forEach method takes a function that gets invoked for each key/value pair in the Map , in insertion order. The function gets passed the value, key and the Map object on each iteration.
No, you can't; if you try this, you will get a ConcurrentModificationException when you use the iterator after modifying the map.
Your mistake is referring to key and value as methods (with trailing "()" parenthesis) instead of as properties. Try this:
#set ($map = $myobject.getMap() ) #foreach ($mapEntry in $map.entrySet()) <name>$mapEntry.key</name> <value>$mapEntry.value</value> #end In other words, use either a property, like mapEntry.key, or the method, like mapEntry.getKey().
