RE: Iterate Hashmap with s:iterate
IIRC OGNL supplies a pseudo-property "keys" that will
return a list of keys present in the map.

RE: Iterate Hashmap with s:iterate
If I remember correctly, to use the s:iterator tag, you have to use an
object that has an 'iterator()' method. HashMap does not implement
java.util.List...
To iterate over a Hashmap, get the keyset [tempMap.ketSet()] from it.
The keyset is a List and you can get an iterator from there.

Subject: Iterate Hashmap with s:iterate
I have an action that returns a hash map that I need to output both the
key and value, but I can't figure out how to access each property with
s:iterate. Any suggestions would help.
The HashMap is being set in my action and returned populated (verified
with ).
// Action snippet
Iterator categoryPhysPropsItr = getCategoryPhysProps().iterator();
Map tempMap = new HashMap();
tempMap = new TreeMap();
while (categoryPhysPropsItr.hasNext()) {
DruglistDrugproperty prop = new DruglistDrugproperty();
prop = (DruglistDrugproperty) categoryPhysPropsItr.next();
tempMap.put(prop.getDruglistDrugclass().getDrugClassName(),
prop.getDrugService());
}
setDrugClassPropsSrvc(tempMap); // HashMap that needs to be
iterated through // end Action Snippet
// Display JSP
Key (
Value ()
// end Display JSP
Thanks,
Cory
