Best practice for database access in flow layer

[Adam Ratcliffe <ad...@premasys.com>]

I'm looking for a little direction on the most appropriate way to access
a database from the flow layer. 


function searchCategories(locType, class1, class2) {
    var categories = Search.searchCategories(locType, class1, class2);
    if(categories != null) {
 // if search returned categories, search again on expanded categories
 cocoon.sendPageAndWait("page/showCategories.xml", {"categories" :
categories} );
 
 // when user request arrives
 class1 = cocoon.request.getParameter("class1");
 class2 = cocoon.request.getParameter("class2");
 
 // recursively calls itself with 
 searchCategories(locType, class1, class2);
    }
}
