There are a lots of different ways of doing that. What I would do is:
1. add a field for the first action wit getters and setters for the params
2. in the jsp do something like:
<script>
var param1 = "<s:property value=''param1' escapeJavaScript='true'/>";
var param2 = "<s:property value=''param2' escapeJavaScript='true'/>";
</script>
3. Call the second action passing the params to Dojo like:
{ 'param1': param1, 'param2' : param2"}
Dojo accepts a map that it serializes into a query string (if it is
GET request). I forgot the dojo method signatures, google it up :).
This way you can avoid building the query string yourself, which is
always error prone.
