uugh stuck again =P getting client side information with JSP/Servlets
Is it possible to NOT use JavaScript and JUST use JSP Script alone? Specifically I need the user's screen size and images that are placed on their browser window (for click and drag functionality) Maybe use a client-side applet? Or can I get the above info in the servlet Response object? If I have to use JavaScropt can I pass JavaScript Variables to JSP Script Variables/Servlets? all input much appreciated, Rich = __ Do You Yahoo!? Yahoo!

MVC question, when to sync the model with database?
using MVC when do I sync my MODEL data arrays with the DATABASE? I would think you would change the database and THEN update your model objects... Good articles on MVC are well appreciated =) thanks, Rich = __ Do You Yahoo!?

please help! hard returns in TOMCAT what the heck?!
the following jsp code:
out.println(input type='hidden' name='scope'
value=');
out.println(MyArray[i].getScope());
out.println(');
out.println(input type='hidden' name='page'
value='0');
results in this output:
input type='hidden' name='command' value='delete'
input type='hidden' name='scope' value='
8
'
Is there a way to STOP the hardreturns that are being
inserted?
thanks a bunch =)

urgent help please!
I hope this is formated well for this list-serv... problem: application scope objects launched by web.xml In my Tomcat boot sequence (web.xml file) I am launching a servlet called InitTwc. This servlet creates and sets the values for an application scope object called TwcMaxes. I have verified that my TwcMaxes object is created in the application scope and its values are set (TwcMaxes.iMaxBookmarks = 3). However once TOMCAT is done booting and when I go to reference the value in a JSP page OR in another servlet the value for TwcMaxes.iMaxBookmarks is 0 (zero). My guess only is that I cannot set values during the web.xml boot up servlet launch, I hope I am wrong. Any help is much apprecited.

application scope servlets launched by web.xml problem
I have some application scope data that I want to share with all the servlets and JSPs in my application. So I load my class InitTwc from my applications web.xml (load-on-startup = 99, i.e. LAST). It launches successfully however when I call the: getServletContext().setAttribute(com.mycompany.app-param, app-value); I get a null error sent to my Tomcat window and the servlet terminates then and there and the rest of my servlet code does NOT execute. Im thinking maybe I cant use getServletContext().setAttribute while loading servlets in the web.xml file ??? All comments/ideas much appreciated! Richard Diaz = __ Do You Yahoo!? Yahoo!

Session variables RAM vs. DB Queries
I'm currently doing DB Queries and holding the users information in session objects... trying to keep the query load on the database down to a minimum by using these session objects (MVC2). My question is where do I draw the line as far as how much RAM each user gets? When do I free up those session objects and querying the database for information again? Are there any guides on this? thanks in advance, Rich __ Do You Yahoo!? LAUNCH - Your Yahoo!

how do i use session.setAttribute for arrays?
Here's what I'm doing:
int iMaxBookmarks = 25;
Bookmark[] MyBookmarkArray = new
Bookmark[iMaxBookmarks];
while (rs.next())
{
MyBookmarkArray[i] = new Bookmark();
session.setAttribute(MyBookmarkArray[ + i + ],
MyBookmarkArray);
// set all data for MyBookmarkArray[i] (this works
fine)...
}
// Close the ResultSet
System.out.println(bookmarks done);
rs.close();
in my JSP page I get a NULL POINTER EXCEPTION... I can
see all my non array session variables just not this
array one... a scope problem?
Also, anyone know of a good JSP Forum?
thanks in advance.
