Displaying a list in JSP

Question

Hi guys,
I'm struggling to find any examples of how to display a list of data in a custom JSP page. I will have some type of holding object to contain an array of BPM Objects. I would like to display one table row in the JSP for each object.
Does anyone have any examples of what format the instance variable should be and how i can map this into the attributes and iterate over this in the JSP.
thanks!

Here is some js code that calls the method 'getByRegion' on the myInfo view object, that I had passed into the jsp. Here is an example of how to populate a Dropdown list in the jsp, with the returned values... Its not on the same line as what you wanted, but will give you an example of using ajax to call a bpm method.
function regionSelect(regionValue){
     var sel = document.getElementById("entity");
     sel.options.length=0;
     var myurl = '<f:invokeUrl var="myInfo" methodName="getByRegion"/>';
          $.get(myurl, {name: regionValue}, function(data){
               for(i=0; i<data.length;i++){
                    sel.options=new Option(data[i].key + ' - ' + data[i].value,data[i].key, false, false);
          }, "json");
And the BPM Method code:  Note, its returning a JSON string here.
This takes a java.util.map (requestParams) as an input argument.inAr as String[] = String[](get(requestParams, arg1 : "name"))
inVal as String = toLowerCase(inAr[0])
entity as String[]
entityId as String[]
sql as String = "select ENTITY_ID, ENTITY_DESC from vm_opts_coun_reg_entity where region = '" + toUpperCase(inVal) + "' order by entity_id"
for each row in executeQuery(DynamicSQL, sentence : sql, implname : "AppDB") do
     entity[] = String(row["ENTITY_DESC"])
     entityId[] = String(row["ENTITY_ID"])               
end
retString as String = "["
for i in 0..length(entityId)-1 do
     key as String = entityId[i]
     value as String = entity[i]
     retString = retString + "{\"value\" : \"" + value + "\",\"key\" : \"" + key + "\" },"
end
if length(retString) > 1 then
     retString = substring(retString, first : 0, last : length(retString)-1)
end
retString = retString + "]"
return retString
HTH!
