how to make a connection to datastore inside jstl tags <p>I'm making a project on Google App Engine and in one of my jsp files, I want to search an entry in my datastore. I normally do this search by clicking on a button on this jsp page, then I make the connection to datastore in a servlet and then I send the query results to jsp back . Well, I want to query datastore without clicking this button. When I load the page, I want to see the query results on my page. When I was using EL tag lib, I could do that by just typing &lt;% %>, now I'm using jstl tag lib. So is there any way to do ? After using jstl tags, I'm not able to use EL tags.</p>
