Cost of a jsp site

I'm new to Java Server Pages and want know what the cost of setting up a JSP site would be (ie: what software do i need; is it free or does it cost and if it is free is it worth getting). I am not interested in the cost of hardware.
Thanks,
Chris McCorriser

The downside to both of these is
that there is no technical support. Not strictly true. There is plenty of info in forums and lists like this, for both apache http server and tomcat. It depends what you mean by support. If you want to be a 'Gold customer' and have someone at the end of the phone 24-7 who can sort out any of your problems (**yawn**), then fine... I'm sure it will be great experience for you!You won't get that with Apache Foundation, but not all (hardly any?)new ventures have the money for that sort of setup anyway...
There are loads of survey estimates that put figures of up to 75% of all webservers being apache. Must say something surely?
What I would say tho, is that large amounts of support info for apache assume you are on a UNIX-variant platform... which admittedly is a far better solution, but not so helpful if you are a Gates disciple.

Implementing if-statement in jsp-sites

Hi,
I have a Vector in a jsp-Site as a property that I can refer to in the following way:
<c:set var="mo" value="${requestScope.montag}"/>
Now I want to test if the second element of this vector equals "0" or not.
I tried things like:
<logic:equal scope="request" name="${montag[0]}" value="0">
or
<logic:equal parameter="${requestScope.montag[0]}" value="0">
but they don't work, does anybody of you have an idea?
Kind regards
Thomas

Internal error if pointing on jsp-site

I set up the Sun ONE Webserver 6.1 SP2 and deployed a webapp named prodass3. It functioned, but displaying jsp-sites.
If I point to a HTML-site within the webapp, the HTML-site is displayed correctly. Access-log entry:
192.168.200.53 - - [08/Jun/2004:17:34:55 +0200] "GET /prodass3/index.html HTTP/1.1" 200 1734
But if I point to a JSP-site, I get an internal error. Access-log entry:
192.168.200.53 - - [08/Jun/2004:17:46:42 +0200] "GET /prodass3/index.jsp HTTP/1.1" 500 305
I think the JSP-files would not be compiled. But there is no error or something like that..

I can't find in server.xml a 'wrong' classpath like you mentoined above.
I also copied the jdk (1.4.2) from the developing environment on the server maschine and linked the java home to the new path.
I also restarted the virtual server..
Here the server.xml:

After closing an Applet, how can I say a HTML/JSP Site to load a new site?

Hi!
I have a problem. I�m writting a little chat, and after qutting I want to say my HTML/JSP site to load or go further to another page.
This is possible because a saw this already, but i didn�t got the way how!
Thnx
Ren�

Hi,
I assume you mean with "after quitting" pressing the Quit button.
Your JSP can use the forward-statement to move to another JSP or HTML. You can find it on Suns
JSP-Syntax Card.
I hope I could help you

Jsp sites access control

Hi,
i am new in web-app-programming.
I have developed a few jsp pages. One of them is login page and the other should only be accessable after logging in the login page.
The current state is: the pages can also be accessed directly with the url like this: "http://localhost:8080/application_root/my_url_pattern/somepage.jsp".
I am looking for a solution to avoid the direct access per url.
my ideas are:
1) set the render control of the jsp site-> it works well-> but a bit complex
2) out source the jsp site -> save the jsp sites somewhere else as the applicationroot-> I have the problem that the site could no be found. Can somebody tell me how can i solve this problem.
thank u
Ming

You can set up a servlet filter in the web.xml. That lets you intercept every single request to certain areas of the app, and modify/redirect it if necessary.
Example: This sets up a filter that runs on all requests to the "/tools" directory:
In web.xml:
   <filter>
     <filter-name>testFilter</filter-name>
     <filter-class>com.TestFilter</filter-class>
   </filter>
   <filter-mapping>
     <filter-name>testFilter</filter-name>
     <url-pattern>/tools/*</url-pattern>
   </filter-mapping>And an example java class of a filter. This one just logs the request URI.
package com;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
public class TestFilter implements Filter{
     public void init(FilterConfig arg0) throws ServletException {}
     public void destroy() {}
     public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
          if (request instanceof HttpServletRequest){
               HttpServletRequest req = (HttpServletRequest)request;
               System.out.println("Servicing request for " + req.getRequestURI());
               chain.doFilter(request, response);
}

Using sjsws to host many small servlet/jsp sites on one server

Hello. I visited the web page at http://www.sun.com/software/products/web_srvr/features.xml, which mentions that sjsws supports mass hosting of thousands of domains. Anyone knows more information about this feature? I want to find out whether sjsws is a good choice for hosting many small servlet/jsp sites on one server.
Some time ago, I tried using apache+tomcat to host many small servlet/jsp sites on one server. But the result was not satisfactory. If a private tomcat/jvm is used for each site, too many resources are consumed and as a result, not many sites can be hosted on one server. If a shared tomcat/jvm is used for all sites, the resources consumed are reduced, but it becomes very difficult to isolate the sites. Is it possible to overcome such problems with sjsws?
Thx.

Of course you dont have to use multiple VMs to host multiple applications.
You can either choose to have multiple Virtual Servers, all in one instance of the web server, serving multiple applications. In this case only one java VM is used.
Or you can go in the route posted in the link above, in which there is only one "physical" virtual server, with many dynamic virtual servers.
Whether you chose to have many multiple web applications, or do the server division in a similar way to what is described in the blog, it is up to you.
Many different web applications will give you more fine level control on the application separation, but it will probably also mean greater resource consumption associated to the web application managing.
Less web applications, but with dynamic separation, in a similar way to what is described in the blog, will give a lesser control on the applications, but will save you a good number of resources.
SJS Web Server is known to work in massive web sites, with very high number of JSPs and Servlets. There is some real life examples of this massive hosting. Maybe others can provide some numbers here :P

Listing JSP site on search engines

I am hoping that there are some methods to get dynamically JSP generated webpages listed on search engines. I know that there are issues when using a query string because of spiders avoiding the '?' Is there a mod_rewrite type of option that can be accomplished in web.xml or anywhere else that could translate a site so that I could use:
http://somesite.com/product/id/324
instead of:
http://somesite.com/product.jsp?id=324
Even if there is a completely different approach to solving this, I welcome any and all suggestions.
Thank you all in advance,
Steve

Or, to make your site more portable (if this is an issue), design your pages such that direct access without query variables provides a meaningful result in the first place, and your problem is solved. I know i have a habit of just erasing extra query stuff on pages i'm viewing to try to get to a root page.. it's incredibly annoying when one doesn't exist, or craps out on you because you're missing parameters.
Although using Apache is a good idea... hadn't thought of that.

Deploying against a JSP site using JSTL

I am reviewing Contribute for use at my company. Our current
corp site is deployed in JSP and makes extensive use of the Java
Standard Tag Library, especially for writing dynamic URLs to
content such as images, pdf, and application download.
Can Contribute and/or my site be configured in such a way
that contributors can edit the JSP pages? I've exploded the war and
deployed it as a set of standard files so Contribute can access the
files, but Contirbute doesn't resolve the JSTL references.
Help!

contribute was designed to allow editting of static HTML
content only.. It does not have the capability to edit anything
dynamic.. It would be better to use Dreamweaver..

PHP on jsp site

Hi all,
I have a problem. We have a portal (weblogic) and we want to integrate into portal
sites that developed in php. Is this possible?
Thank you
Tamas

JSP without java is a bit like PHP without html
...only worse.Which is why I'm looking for a book or onlinetutorial
which teaches Java with a focus on JSP.Well that's nice ...but YOU were the one who asked for
advice from people who you may assume to know more
than you do. Take it or leave it, makes bugger all
dif'rence to me ... erm, learn java first.I want to learn Java, but I don't have much use for it outside of JSP. Aren't there any books which teach Java, but in the context of web development?

Cost for Production at Site

Dear All ,
I want to capture the cost of the work caried out at my customers site by employees of my company.
I have near about 100 sites at present and my project tenure is about 2 to 3 years
How can i collect the cost similar to the production order in my plant.
Shall I define the plants for each and every site?
Replies will be highly appreciated.
Regards,
Mandar

Dear Mandar,
1. The request you have posted here, needs a larger discussion interms of integeration with other modules, configuration, Master data Etc.
2. A simple solution is that you can have cost centres to collect the same at the customer leve.
3. This will be simpler, but again it needs to be validated with what cost you are planning to collect and how.
4. Defining a plant alone will not resolve your problem, plant is only a organisationa entity- cost are collected at Cost centres only.

2nd low-cost camera for on-site shoots

I use the Panasonic HVX-200p for my studio work which is almost all green screen and usually shot at 720p30 or 720p60. I capture direct to my workstation using OnLocation CS4 via firewire.
Now I need a 2nd camera to capture on-site, outdoors mostly, but possibly some indoors. End use is educational DVD's and perhaps online courses, probably in H.264, so I don't need broadcast quality.
I need to go cheap on this because of my budget. I have little knowledge, but how about an inexpensive DSLR? My concern with these is that the codec is AVCHD [I think] and I've read about how this strains the PC requirements, is not easily digested (unless that's improved with CS6), etc. (see my Profile for workstation specs). Also, I'm not sure how it would look with the Panasonic keyed footage.
There is another option: carry a laptop with OnLocation CS4 installed and capture with it using the Panasonic. Granted, it is cumbersome and hinders in other ways, but it is possible. This choice, if acceptable, would require me to buy a laptop with a decent battery life (my existing laptop is an older, core 2 duo & the battery died long ago). I'd like to hear opinions on this because I don't know if this option would be cheaper than a new camera and/or give me better quality.
Anyway, I think you get the idea. I am most grateful for all recommendations. I am willing to consider used cameras, if that works.
Paul
P.S. I need at least one wireless microphone.

Hi Paul,
Both my cam's are panosonic, and though a little above the one in question in terms of price range, i can give a little feedback on what is similar between them.
Apart from the dreaded AVCHD problems CS5 and early versions of CS6 had, you shouldn't have to much trouble with it.
Both of my cams;
AG-AC130
Panasonic AG-AC130 AVCCAM HD Handheld ... - B&H Photo Video
& AG-AC160
Panasonic AG-AC160 AVCCAM HD Handheld ... - B&H Photo Video
use the dual SDHC cards, apart from making sure you copy the entire card, you will be fine. The file structure has to be completely intact otherwise timecode, audio and spanning clips will get messed up and cause you headaches.
My cam's are extremely good in low light, stomp all over the famed Sony Z7's of yesteryear. As long as your not shooting anything fast moving, if you need the light lower the shutter speed to 1/25 and open the iris right up you will get decent footage in lower light situations.
One thing you won't get in that model is the DRS function which is revolutionary to say the least, in a nutshell it supresses overexposure and boosts shadows.
In addition you'll have to xlr inputs so add wireless, or even a boom mic (much better price to quality ratio) with ease.
The GoPro's are amazing, but in my opinion totally sh*t in low light situations. People will argue that the newer models are much better, but I hate any grain. Another option with your low light requirements would be to add one of these Z96 LED, They are amazing for the size, easy to attach to a hotshoe, dimmable and unbelievably bright. Color temp isn't bad either, can be a bit cold\blue at full kick but has two magnetic diffusers ( i usually just manually change the temp in cam but lower budget cameras don't often have this function). Even doing an Auto WB would help to correct the temp.
Hope this helps you a bit

Hi Dimitri,
as Astrid said, it is more than probable that the problem comes from the expression within the tag.
If this works on Tomcat, carefully analyse the tab library, check against which JSP version it is developed and should run on, on which server you are and which JSP version there is supported.
In the end, if you are "lucky", you maybe will have determined that it is a bug in SAP's JSP processor. In this case, please open an OSS message to report it.
Hope it helps

Ooops, just saw you gave the info WAS 6.40, that means J2EE 1.3, and that again means JSP 1.2.

What is a Site Link Cost?

I'm a Student trying to get MCITP. Please tell me when i am configuring Replication between sites, What is the site link cost means? What can i do from that? please tell me

Hi Ashane Deshapriya,
The cost setting on a site link object determines the likelihood that replication occurs over a particular route between two site. Relication routes with the lowest cumulative cost are preferred. You can use this procedure to configure replication cost on
the site link object in Active Directory Domain Services (AD DS). When you create or modify site links, use the site link object properties to configure the relative cost of using the site link.
For your information, please refer to the following articles to get more help:

Newbie - JSP & bean shopping cart logic error?

Hello,
I am attempting to bulid a shopping cart facility on a JSP site that I am building.
I am having difficulties adding an item to the basket.
The page below (bookDetail.jsp) displays items for sale from a database. At the foot of the page, I have set up a hyperlink to add an item to a basket bean instance created in this page.
What happens is the page will load correctly, when i hover the mouse over the hyperlink to add the item to the basket, the status bar shows the URL of the current page with the details of the book appended. This is what I want. But when I click the link, the page will only reload showing 20% of the content.
Netbeans throws up no errors, neither does Tomcat, so I am assuming I have made a logical error somewhere.
I have enclosed the Book class, and the ShoppingCart class for your reference.
Any help would be really appreciated as I am at a loss here.
Cheers.

      public Product(
                       String productID,
