Connection to database from jsp.
We have a system consisting of a group of jsps - which have links to one another. There is no controller servlet as it is a simple system. What i want is to access the database from the jsps. The problem is that I do not want a new connection to be established everytime a request is made. What is the solution for this? I had initially thought of having a utility class and in that I can have a getConnection method which returns the connection to a static connection reference in the same utility class. This can then be assigned to the jsps (by making a call from the jsps to some method - returnConn, in the utilily class). Is it true that a new connection will be established everytime. This has confused me a bit. I am infact confused now about the very concept of static references. How do you think this problem can be solved? Will a servlet be of any use? Actually in a servlet, if we have a static connection reference as a class variable, and the initialization is done ( acquiring a connection) in the init method ( as init is executed only once in the lifetime of a servlet), the problem may be solved. In a servlet, the init method is executed only once and the servlet does not go out of memory till the server comes down. So I presume the connection will also be the same. Is this correct? Even if it is, I want to avoid the servlet, as it will be a lot of rework if the servlet has to be fit in. The application would have to be changed. Suggestions invited.

Moving client from one web app into another
Hi, I'm not sure what to do here, I have a general set of jsp pages open to the public, these are in a webapp with its own web-inf directory, classes etc. Then I have a secure webapp, starting with a logon page which you get to from a link in the 'public' website. The secure part of the site uses certificates and ssl and is a self-contained web-app, also with its own web-inf etc. My question I guess is this, can I deploy two or more web applications in the same container at the same time? Would I give each one a different port (connector) in the same Service (in the server.xml), or would each require it's own 'Service' tag altogether? or what? Sorry if my question is confusing, or if I'm making complicated things out of something simple, I'm just a bit confused.

Override jspInit() in a declaration block, create the connection, and save it as an attribute in ServletContext. -- padhu Anoop Kumar V wrote: >We have a system consisting of a group of jsps - which have links to one >another.

Server-Side ActiveX technology
Hi, this question is in relation with Java and JSP. It is possible to create an instance of an ActiveX object (i.e. accesing an automation server like Word, Excel) at server-side with JSP (Java) and achieve the same functionality as at client-side with JavaScript (or JScript)? I already access Word from JavaScript with the function ActiveXObject. I'm searching a similar manner to obtain the same behavior, but at the server, (supposing the server is a Windows server). For those who are Java-JSP-adicted: ASP already do that. :) I'm joking... Himar Carmona Delgado Analista - Programador .. DESIC, S.L. (Desarrollos y Sistemas Informáticos Canarios, S.L.)

Re: about getRemoteHost()

Re: Are servlets faster?
JSPs are just servlets. With servlets there's a marginal amount of performance saving since the JSP model does some initialization for you (getting session, servletcontext). It also uses an array to point to the hard-coded (HTML) source that has slightly more overhead then other data structures. With servlets you could some of the speeding up (setting class as final) of the language that you couldn't with a JSP. The actual rendering that you are probably doing through JavaBean calls would remain the same speed though. - Original Message - From: "Campano, Troy" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, October 16, 2002 3:55 PM Subject: Are servlets faster?

David, Thanks for the quick response, but I was looking for something a little closer to ping. I'd like to send out several packets of the same size and track the time it takes to get them back. But as I say, I'm not knowledgeable about networking, so I'm having trouble figuring out where to start. I looked for an off the shelf product, but haven't had much success finding that, either. -Original Message- From: David Marquis [mailto:[EMAIL PROTECTED]] Sent: October 16, 2002 - Wednesday 2:20p To: [EMAIL PROTECTED] Subject: Re: Checking client connection speed You could send a bunch of characters to the client and measure the time it takes to transfer (with somewhat of a timer) and then, since you know the size of what you're sending, you could easily calculate the speed.

Re: Checking client connection speed
Hi, The first thing that comes to mind is to use a javascript/java in a page running on the client side that would report the results to your JSP/servlet page. The main advantages are that you don't need to wory about firewalls on the client side, and the work is done on the client side, so you don't need to worry about timeouts and stuff like that. There are quite a few sites on the net that let you measure the speed of your connection. Find one, and see if you can figure out how they do it. It doesn't sound like a small task.

Re: Checking client connection speed
Garann, A very simple way to do it is by having a page following this pseudo-code: 1. var start = current time 2. write some HTML (or JavaScript) comment containing n characters 3. var end = current time 4. store 'end-start' in a hidden field of some HTML form and post back the form Because browsers execute JavaScript statement as they are received from the server, if you flush the server output right after steps (1) and (3), you will get in the hidden field the time it takes to send n characters to the browsers (a very good approximation of it, anyway).
