If so, you may need to somehow track the state of your session between your portlet and the servlet it is 'hosting'. One simple way is to write the state into a query param or directly into the HTML(into an INPUT) A more complex way would be to completely proxy the whole session.... Also, you will also need to rewrite your links (something like in the WebPagePortlet, but you want to rewrite back to Jetspeed) > Q: > If I want to add a portlet for user to do database search, what is the > best/easist way to do it? any advice? > You can use whatever you like to access the database in Java (JDBC comes to mind...), callout to any methods. Don't recommend putting db code in the portlet, abstract it out, layer your data access.
