Servlet and JSP combination and design issue

My task is to generate the list box dynamically based on the input XML file.
I create a JSP page and a servlet.
http://www.myserver.com/page1.jsp
In page1.jsp, I have the following to call servlet from JSP page
<jsp:include page="myproj.TableGeneration"/>
In my case, I think I don't need servlet at all, but just Java Bean
class to generate the table. And JSP page call that Java Bean class.
But in what situation we need the combination of servlet and JSP?
What do you think? Any ideas? Thanks!

Trying to keep the data separate from the view is always a good idea
I have used XML in a similar way - the XML is the data, this is read and it is uses to populate various page beans - the beans are then simply used in the JSP page to get the information only

Flex and JSP tutorials and articles?

I found one that doesnt really answer most of my questions: http://cookbooks.adobe.com/index.cfm?event=showdetails&postId=7746
I am looking for more information on setting up flex applications that can sit ontop of JSP pages and utilize the code to interact with the back end data base to display, gather, send and retrieve data. I like the whole "not having to refresh when new data comes in" concept.

It depends on how Flex is getting the data, and how it's generated. If you refresh the page, then the Flex app will be reset, and won't have any knowledge of previous data. One thing you could do is store the data on the server and access it via some web-service calls (eg AMF or REST). The server could manage the user's session, store data, and generate or retrieve previous data.

I want to copy video, cutaways and audio combined and use in another project. So far I can only copy the video clip or one of the other elements at a time. How do I group all of them?

I want to group my video clip with its audio and cutaway clips so that I can copy the segment and move it to another project. So far I can only move one element at a time. How can I group all the elements?

You can select multiple objects in the timeline in the usual Mac way - hold down the shift key while you click on the objects then copy, select other project, position playhead where you want to insert then paste.

How to master good design with EJB and JSP?

I use JSP to calling EJB. But the .jsp file is complex and it's difficult to maintain...I just want to work higher efficent with EJB,JSP and JavaBean. I want to know is there a good design with EJB and JSP? and is there any good material about MVC for EJB,JSP and JavaBean?

You should read the J2EE blueprint available on this website. Better download the PDF, and print it for yourself so you can read it anytime.

How to combine servlet and jsp

I'm doing a project. My friend using jsp. and i using servlet..
we are confused, how to combine servlet and jsp. or we can just use redirect??
but it's still doesn't work properly...thanks for your helpp

You can use RequestDispatcher interface for calling a JSP from a Servlet, or vice-versa.
Following is the code for sending output to a JSP page from a servlet:
javax.servlet.RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(�/Ashu.jsp�);
request.setAttribute(�Name�,�Ashutosh�);
dispatcher.forward(request,response);

InterMedia Java Classes for Servlets and JSPs and Netscape

I am using the interMedia Java Classes for Servlets and JSPs to upload and retrieve multimedia data. I have found that it is much more performant in Internet Explorer (5.5) than in Netscape Communicator (4.7). In fact, I cannot upload images larger than 10K at all using netscape. However, the same image can be uploaded into the same application using IE. Is this a known issue?
Thanks in advance.

Hi,
We have successfully uploaded multimedia data in the giga-byte range (Quicktime and AVI files) at the same speed with both the Netscape (4.7n) and MS IE (4.n and 5.n) browsers. One thing we have noticed is that its very important to set the manual proxy settings correctly if you have an environment with a proxy server. If you don't, then uploads can go via the proxy server and, for some reason, that seems to take considerably longer. For example, suppose you are in the www.xyzco.com domain and are connecting to a host named webserver.www.xyzco.com, then specify webserver and webserver.www.xyzco.com (to cover both cases) in the "Do not use proxy servers for..." box in the manual proxy server configuration screen. Also, if you're using a tool such as JDeveloper that uses the host IP address in the debugger environment, then you also need to add the numeric-based (nnn.nnn.nnn.nnn) IP address to this list.
Hope this helps.
In order to better understand the variety of ways in which our customers are using interMedia, we'd be very interested in knowing a little more about your application, the interMedia functionality that you are using, and how you are developing and deploying your application. If you are able to help us, please send a short email message with some information about your application, together with any comments you may have, to the Oracle interMedia Product Manager, Joe Mauro, at [email protected] Thank you!

URGENT.........File Upload using Servlets and jsp

I am a new servlet programmer.......
iam using tomcat server......
can any one pls help in writing code for file upload using servlets and jsp without using multipart class or any other class like that....
Please URGENT..

Slow down! "Urgent" is from your perspective alone. I, myself, am not troubled or worried in the least.
hi ugniss
thanks for ur reply....sorry i was not
y i was not asked not to use multipart class or any
other class like that...is there any other
possibility to do file uploading from jsp to
servlet...
Just as an aside, a JSP is a Servlet. But even if I move beyond that, the question does not make sense. If you want a "JSP to upload to a Servlet", then simply do so in memory. You are still (likely) within the same scope of a given request. However, if instead you are referring to a JSP that is displayed on a browser, then really you are talking about HTML, which is what the browser will receive. And since you are now talking about a browser, your only real, viable option is a multi-part file upload. So, it is either server or it is browser. And either way, the question leads to very established options, as outlined above.
the main concept is.. in the browser the user selects
a particular file and clicks the button upload..after
clicking upload the jsp should sent the file to the
servlet in streams...there the servlet gets in and
saves in a server location........this is wat i hav
to do...
Okay. So, after reading my previous (redundant) paragraph, we have arrived at the crux of the issue. You have a JSP that will be output as HTML to a client (browser) which you want to upload content to your server (handled by a Servlet). So, you are now stuck again with multi-part. The requirement to not use multi-part is non-sensical. You can overcome it, say, if you write your own applet or standalone Swing client. However, if your users are invoking this functionality from a browser, you are limited by the options that W3C has provided you. Use multi-part.
is there aby possibilty to do this.....can any one
pls help....Take the advice to download and review Jakarta Commons FileUpload. Inform your management that their requirement makes no technical sense. Research on your own. There are dozens of examples (and tutorials) on file upload using multi-part. Embrace it. Live it. Love it.

How to use servlets and JSP for my homepage?

servlets and JSP are server-side program. If my homepage is on some web-hosting websites, can I upload the servlets and JSP to run it? if possible, where can I find such a web-hosting place?
sraiper

Not many hosts offer JSP or Servlet support (and some do but then stop and never give you a refund, grrrrrrr!!!!).
Also, ones that do support it can often be more expensive. There are some free ones but all the one's I've come across have problems that made them unsuitable for my needs.
Here is a list of hosts that support Java:
http://www.thejspbook.com/resources/category.jsp?id=1005&name=JSP+web+hosting
I can't comment on any from that list, however I use http://www.positive-internet.com they are a bit pricey but they have excellent support and are always happy to help with any Tomcat (the JSP/Servlet server they use)configuration issues or needs that you may have.

How to install servlet and jsp on win xp?

I am new in jsp and servlets. I would like to follow some jsp books and examples. The j2eesdk-1_4-dr-windows-eval.exe is already installed on my computer. I can write and run java codes. I downloaded the jsp-2_1-edr-api.zip file from http://java.sun.com. I extracted and moved to dir:\Sun\AppServer\ folder. When I search, I cannot see any jsp.jar file as some documents say, nor servlet.jar. How can I install jsp and servlet on windows xp? Any help? I will be very grateful.

For starters, you would probably have better luck getting an answer on the general Java forums, since this a very general question- it is hard to see how this is specific to the Web Application Framework technology, except of course that it uses JSP and servlets naturally,
But to try to help you here, more information is needed: from exactly where are you do\wnloading the file jsp-2_1-edr-api.zip and what is the product title of this file? I ask this since a general search of sun.com returns no evidence of the existence of this file.
Also, what documents are being referred to here?
Thanks

Creating FOrums with Servlet and JSP

Hi everyone,
Is there a good resource that explains how to build a forum using servlets and JSP technology?
Regards,
Basil Mahdi

please let me know here if you find any useful resources...I am in the process of writing my own searchable threaded forum for my company with JSP's/servlets. It's a very slow process at the moment though...if I ever finish it, I'll gladly share it.
