Hello I am trying to create a single select parameter drop-down list (input box) where the values for the parameter drop down list are populated by values from a database field and/or query. Every example I see for a tutorial on this subject, tells me to use the java.util.collection class for the paramter. When I try and select the java.util.collections class from the parameter advanced properties definition, it is not listed. Do I need the java.util.collections class to make a parameter (input box) drop down list work or is it not required now? If I need it, where do I get it and how to load it so that it appears in the parameter class selection. thank you Tony
