    1. COI changed it to VelocityViewServlet, and the Properties class to ExtendedProperties ( had an error over there, after changing to extends VelocityViewServlet) and now, when i run the program i get an error like this one: type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: Servlet.init() for servlet velo.Login threw exception What does it mean?

    2. COI changed it to error= request.getAttribute("error").toString(); to see why do i have a java null pointer exception, and the error, is at this line, it all works fine, till it gets to it. I tried putting a request.getAttribute("error").toString() in other parts of the code, not in the Template function and no errors. PS: In the template (login.vm) how do i declare <%@page import="a.userBean"%>

    3. COInternal errors generally have a root cause which gives more informations. You should check your servlet container log file if the displayed internal error is not explicit enough. If you don't solve related problems by yourself, please try to identify and post here only the most relevant lines. Your P.S. has nothing to do with your original question. I guess you will have to put your userBean somewhere (why not as a session attribute?) from your Java code. Remember that you can reach J2EE attributes from within your templates with $request, $session and $application.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
