Jsp and asp integration

This might sound like a stupid thing to do.
If I have a main website developed in jsp and I want to pass information (variables) from it to another component of the same site developed in asp on a separate server is this possible?
If so how might one do it?
Many thanks
Paul

It's not a stupid question! You can even have both ASP and JSP on the same server - IIS! Of course, you have to have JSP container installed to process your JSP/Servlets.
How to do that? Install IIS (Microsoft Internet Information Server) (usually working on standard web port 80), also install Tomcat on the same server. After that you have to install ISAPI filter on IIS. That's the component that will filter all HTTP requests for pages with JSP extension from your IIS server and redirect them on Tomcat for JSP/Servlet processing.
E.g. if you have installed ISAPI filter for Tomcat container and you have INFO.ASP and INFO.JSP on your site. IIS will process ASP and send the result to your client. Also, if client requests INFO.JSP, ISAPI filter will recognoze from HTTP request that this client is asking for JSP page and it will redirect this request on Tomcat which will process this JSP and return the result to the user again.
APS and JSP pages can communicate among each other through POST or GET methods. For example if you request INFO.ASP?user=John or INFO.ASP?user=John both of them are capable of dealing with parameters (user) and each of them can redirect request to other one.

Difference between JSP and ASP

Whatz the diff between JSP and ASP

Hello msdnexpert,
Active Server Pages (ASP) allows you to build rich, data driven, dynamic complex applications. ASPs are written in Perl, VBScript, C/C++. They run on machines running Microsoft Windows. With ASP, an HTML page on a web server can contain snippets of embedded code. This code is read and executed by the web server before it sends the page to the client (usually a browser such as Netscape Navigator or Microsoft's Internet Explorer.) For more information on ASP see:
http://www.microsoft.com/workshop/server/default.asp
or
http://www.activeserverpages.com
Java Server Pages (JSP) also allows you to build rich, data driven, dynamic complex applications. JSPs are written in Java. They run on any Java enabled machine, including Solarlis, Windows, Linux, and Mac OS. JSPs also makes available all of Java's industrial strength security for free. JSPs uses a syntax similar to ASP except that the scripting language is Java. Unlike ASP, JSP is an open standard implemented dozen of venders across all platforms. JSPs are closely tied to servlets because a JSP page is transformed into a servlet as part of its execution. For more information on JSP see:
http://java.sun.com/products/jsp
A servlet is a generic server extension -- a Java class that can be loaded dynamically to extend the functionality of a server. Servelets are commonly used with web servers, where they can take the place of CGI scripts. A servlet is similar to a proprietary server extension, except that it runs inside a Java Virtual Machine on the server side, so it is safe and portable. Servlets operate solely within the domain of the server: Unlike Applets, they do not require support for Java in the web browser.
Unlike CGI, which must use multiple process to handle separate programs and/or separate requests, servlets can all be handled by separate threads within the same process or by threads within multiple processes spread across a number of back end servers. This means that servlets are also efficient and scalable. Because servlets run with bi-directional communication to the web server, they can interact very closely with the server to do things that are not possible with CGI. Another advantage of servlets is that they are portable: Both across operating systems and across web servers.

HTMLDB webapp's scalibility, relibility, and performance vs JSP or ASP apps

I am new to HTMLDB. It seems that HTMLDB is getting more attention now than before. I am interested in it, does anyone who knows it inside out regarding its pros and cons vs JSP and ASP apps shed some light about HTMLDB apps?
I heard that asktom.com is created by it, but it seems that users are limited, is there any enterprise apps created by it, if yes, could you list the url?
Thanks a lot,
John

JSP , PHP, ASP???

i read somewhere that php is far more powerful than JSP and PHP? is that rue??
also for which is finding hosting, cheaper and easier???
Ali

PHP more powerful? Depends on what you mean by power.
In terms of features, no. JSP and ASP have many more features. They have full fledged OO programming languages and API libraries backing them up.
In terms of speed, it can be faster, just BECAUSE it doesn't have to bother with all the features that JSP/ASP provide.
In terms of memory requirements, PHP wins hands down. Java/ASP can be quite memory hungry.
They all do basically the same stuff at the end of the day - generate dynamic web pages.
For a lot of simple small-medium size websites PHP is perfectly fine.
ASP and .NET can provide many more features, but you are tied to MIcrosoft platforms.
Java/JSP is the best (of course - how can I say other on a java forum) - provides a good balance of speed/power without tying you down to a specific platform
You will probably find hosting easier for PHP/MySQL than you will for the other technologies, though I can't say with any certainty. I haven't really looked myself :-)

Integration of JSP and xhtml in jsf project

Can we use both jsp and xhtml in single jsf project. Actually I encountered a problem while configuring jsp and xhtml in web.xml of jsf project. The web.xml configuration file allows to use only one view handler (jsp or xhtml).By default it use jsp view handler. For xhtml view handler, we need to define following context param -:
<context-param>
<param-name>javax.faces.DEFAULT_SUFFIX</param-name>
<param-value>.xhtml</param-value>
</context-param>
Please let me know any possibility to configure both jsp and xhtml in jsf project(web.xml).
My actual requirement is that I need to forward to new page(xhtml) from an xhtml page without using faces-config. I am not able to find any facelets tags which let me forward to new xhtml page. So I am thinking to use jsp to exploit the jsp tag called forward. But the constraint is that we can use only one view handler with jsf project.

JWSDP and J2EE Integration: Doesn't work. What's the point?

My problems involve the integration of JWSDP and J2EE as described in these two documents:
http://developer.java.sun.com/developer/technicalArticles/WebServices/wsj2ee/
http://java.sun.com/j2ee/documentation/windows_guide.html
It looks like a long one, but it�s really not that bad. All comments are appreciated.
I�ve numbered each line-paragraph-section for easy reference later.
(1) My ultimate goal is to setup a website that displays data from a database. I will use Java, Apache, Oracle, and whatever else I need to create a website that uses servlets, JavaServer Pages (JSP), and JDBC.
(2) I�ve got four Pentium III computers:
1. Windows 2000 Server to be the web server (MyWebServer, IP = 10.10.1.1).
2. Windows 2000 Professional to be the database server (MyDatabaseServer, IP = 10.10.1.2).
3. Windows 2000 Professional that I use to develop and test (MyDeveloperPC, IP = 10.10.1.3).
4. Windows 2000 Professional that I use as a client to connect to the website (MyClientPC, IP = 10.10.1.4).
(3) On MyWebServer I installed the following:
Java 2 Standard Edition (J2SE)
Java 2 Enterprise Edition (J2EE)
Java Web Services Developer Pack (JWSDP)
The JWSDP tutorial
Apache HTTP Server
(4) The files I downloaded and installed are as follows:
j2sdk-1_4_0-rc-win.exe
j2sdkee-1_3_1-win.exe
jwsdp-1_0-ea1-win.exe
jwsdp-1_0-ea1_01-tutorial.zip
apache_1.3.23-win32-x86-no_src.exe
(5) After installing these products, I set the environment variables as follows:
JAVA_HOME = c:\j2se
J2EE_HOME = c:\j2ee
JWSDP_HOME = c:\jwsdp
Path = c:\j2se\bin;c:\j2ee\bin;c:\jwsdp\bin; [and other previous statements]
(6) I checked to see that Apache is running as a service. It is.
On MyWebServer I start Tomcat and J2EE. Both start properly and are operating simultaneously.
(7) From MyClientPC I open Internet Explorer and in the address box I type:
http://10.10.1.1
This displays the page c:\ApacheHTTP\apache\htdocs\index.html.en (The Apache default server installation page.)
(8) I then enter this address in IE:
http://10.10.1.1:8080
This displays the page c:\jwsdp\webapps\root\index.html (The default JWSDP page).
(9) I then enter this address in IE:
http://10.10.1.1:8000
This displays the page c:\j2ee\public_html\index.html (The J2EE 1.3 Default Home Page).
(10) So far so good. Now I want to test JWSDP as a container for JSP pages.
(11) I use ant to build the converter app found in the tutorial examples (in folder c:\jwsdp\�\tutorial\examples\gs). I then deploy the converter app to the c:\jwsdp\webapps\gs folder.
(12) From MyClientPC I open Internet Explorer and in the address box I type:
http://10.10.1.1:8080/gs
The converter app works perfectly.
(13) To eliminate the need to enter the port number, I create a link from the Apache default server installation page to the converter app. From MyClientPC and enter this address into IE:
http://10.10.1.1
I then click on the link to the converter app and it works perfectly.
(14) Question: Is this the best way to display JSP pages without having to enter the port number?
(15) Now it�s time to integrate JWSDP and J2EE as described in these two documents:
http://developer.java.sun.com/developer/technicalArticles/WebServices/wsj2ee/
http://java.sun.com/j2ee/documentation/windows_guide.html
(16) After I complete this integration I cannot start both Tomcat and J2EE at the same time. This makes sense because they both share port 8080.
I start Tomcat.
(17) From MyClientPC and use Internet Explorer to test the various relevant addresses. Everything works the same as it did before except this one:
http://10.10.1.1:8000
The page cannot be displayed. The J2EE default home page is not displayed, which makes sense because the J2EE port is no longer 8000; it has been changed to 8080.
(18) Now I shutdown Tomcat and start J2EE.
From MyClientPC and use Internet Explorer to test the various relevant addresses:
(19) http://10.10.1.1:8080
Displays the JWSDP default home page.
(20) http://10.10.1.1:8080/gs
The page cannot be displayed. The converter app no longer works.
(21) From MyWebServer and use Internet Explorer to test localhost:
http://localhost:8080
This displays the J2EE default home page.
(22) Question: Why does localhost give me a different page than the IP address?
(23) Question: What was the point of integrating JWSDP and J2EE?
(24) I want to get the converter app working, so I create a .war file and attempt to add it to the J2EE deploytool (see the two integration documents listed above at section 15.) I create the .war file following the instructions in the JWSDP tutorial:
http://java.sun.com/webservices/docs/ea1/tutorial/doc/WebApp3.html#64606
(25) I change to the c:\jwsdp\�\tutorial\examples\gs\build folder.
I then type:
jar cvf converter.war .
A .war file is created.
(26) I open the deploytool: File, New, Application, and I name it �converter�.
I attempt to add the .war file: File, Add to Application, Web WAR.
(27) When I attempt to add the converter.war file I get this error:
�converter.war does not appear to be a valid web JAR.�
I tried a few different attempts, all with the same result. I�m stuck.
(28) I ask again, What was the point of integrating JWSDP and J2EE?
(29) If this is the preferred configuration, how do I display my JSP pages like the converter app?
Please help!!!

The JWSDP tutorial says to be in the �build� folder of the example when issuing the jar command to create the .war file. The build folder is created when I run the �ant build� command.
Attempt 1 from the command prompt in folder c:\jwsdp\tutorial\examples\gs\build>
I typed this command:
jar cvf c:\jaxmservices\converter.war .
In this case I directed the .war file to be placed in a different folder as you suggested. Here�s the output:
added manifest
adding: index.jsp(in = 921) (out= 525)(deflated 42%)
adding: WEB-INF/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/classes/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/classes/Converter.class(in = 582) (out= 358)(deflated 38%)
Didn�t work. Same error as before.
Attempt 2 from the same folder:
I typed this command as you suggested (I tried it with and without the final dot):
jar tvf converter.war
Here is the output:
java.io.FileNotFoundException: converter.war (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:103)
at java.io.FileInputStream.<init>(FileInputStream.java:66)
at sun.tools.jar.Main.run(Main.java:185)
at sun.tools.jar.Main.main(Main.java:904)
I tried a few other variations on these attempts with no luck. I�m stuck.
I�m attempting to create a .war file out of two files: index.jsp and converter.class.
Now that I�ve integrated JWSDP and J2EE, is there some other way that I can run the converter app instead of a .war file and the deploytool? In other words, if I go back to using ant to build and deploy converter, where would I deploy it so that it will work with J2EE?
By the way, it doesn�t have to be converter. I�d be happy if I could get any JSP page to work in J2EE after the integration.
Forever grateful,
Logan

What's the difference between jsp and jsf?

who can tell me what's the difference between jsp and jsf?
I'm puzzled when I found some of the technology in jsp is so similar to the ones in jsp( javaserver page)

Hi,
Find the difference between JSP and JSF
1. A developer has more control with JSP, but (should) get easier development with JSF
2. Event handling is done differently in JSP (HTTP) and JSF (Java)
3. The UI is designed differently (or should be at least) with JSP (markup) and JSF (components).
4. The end product should also be defined differently - JSP page versus a JSF application.
Is this the only thing that is need to make a decision for either or? Probably not. There are other pieces that need to be taken in account when deciding which technology to use - tools support, enough components, type of application etc.... At this point there are not enough JSF components (although there are some interesting projects underway - Ajaxfaces, Myfaces, ADF Faces, and WebChart 3d) and enterprise tools support is still limited to a few tools vendor. Looking at our ADF Faces components they are currently available as early access (not production) and demands for these components are stacking up, literally, outside my office doorstep. Although I would love to make them production - now! - it is not a viable solution since we are still checking features and fixing critical bugs.
All this combined - not enough enterprise level components in production, lacking tools support etc... - leave customers in a vacuum where the decision is either to continue with JSP, since it is mature and has a wide developer base, or move forward with JSF not sure if the support, or the developers will be there. This is particularly sensitive to customers that need to get started now and be production by summer.
If you are in this vacuum here are some key points promoting JSF:
1. Fundamental unit is the Component
2. Built in event and state management
3. Component sets can be provided by any vendor
4. Closer to ASP.Net or Swing development
5. Choice of UI technology
6. Scale up (rich clients)
7. Scale down (mobile devices)
8. Built into J2EE containers in J2EE 5.0 (tentative)

MVC JSP and Servlets

I'm creating JSP pages to represent the view of the site and servlets to get the request and decide which JSP page to load next.
When the servlet recibes a request it generally has to query the database to get some data and then show it back to the client. To do this the servlet calls other object that is responsible to query the database and fill a ResultSet.
My question is: what is better, to load a Vector with special objects containing the data in the ResultSet and then return this vector to the jsp page for it to use it, or may a return directly the ResultSet to the jsp page? With the first option I have to cycle in the resultSet to load the vector and then cycle through the vector to show the results. With the second option I cycle only once, but I isolate from the database (column names, order in which the things are returned...)
I hope anybody can give me an opinion.
Thanks

There are a few things wrong with this:
1) MVC -> The View should have no Model work init.
For the MVC pattern, the database is Model. Use
a
a ResultSet in JSP, and now your View is lockedto
a
database with a specific column format.
Huh? I think that's backwards. The View willalmost
always require Model data unless it is a staticpage.
The Model, however, should be agnostic about what
t View technology it serves. (The Controllerbridges
the two). Also, I would call the database the
Persistence or Integration tier, a separateconcept
from the Model, though intimately coupled to it.I meant the work of the model (gathering the data to
a presentable form) is moved to the View. Yes, the
View needs to know the Model to be able to display
its data. But the Model should handle the data
collection.
Fair enough. I might have read it backwards as well.
>>
2) Any web application (or any application in
general) wether it uses MVC or not, should still
follow a 3 tier approach: Persistance (Data),Domain
(logic), Presentation (View, output) (note, thisis
different then MVC.) By moving the ResultSet inthe
JSP you would be dragging the Persistancemechanism
up two layers. Generally, a layer should only
see
the layer just below it (Presentation seesDomain.
Domain sees Persistance. Persistance never sees
s Domain or Presentation. Domain never sees
Presentation. Presentation never seesPersistance).
>
I agree that Persistence and View should not seeeach
other. However, Model and Persistence must. How
else do you write a DAO? Or even use a mapperlike
Hibernate?First the Model doesn't fit into just one of the
three tiers (Persistance Domain and Presentation).
The Model of MVC is both the Domain logic and the
e Persistance mechanism.
To me, at least, Domain logic = model. The terms I have normally read is either "business tier" or "model domain". "Patterns of Enterprise Application Architecture", M. Fowler. Though, I will concede that this tier has the least well defined set of terms.
But for the three tier architecture: the domain sees
the persistance. You always see one layer down. So
Domain sees the persistance and pulls the data into
the model. So a DAO would be part of the Domain, the
logic of collecting the data from the database to be
used in the application (in the correct object graph
and all that). The persistance though, doesn't see
the domain.
Hmm, I'm not sure which direction 'down' is. And even if 'down' meant towards the back-end or away from it, what about the controller? It parses view requests and delegates them to the model. The results are then normally returned to the controller for dispatch to a view. So, the controller seems to have its fingers in all the tiers except integration and persistence, at least to me. I think of the controller as the 'middle man' between model and view that lets the model be agnostic to the view. The view and controller will to some extent always be coupled. However, the model theoretically exists on its own.
Half of me thinks that I have a different view on
where the Domain and Persistance border is. I
thought the DAO or the Data Mapper would be in the
Domain, whereas you seem to be saying they are in the
Persistance layer?
That's interesting. I don't know if there is an absolute answer. We are dealing with the O/R boundary, and the DAO straddles the boundary. However, one could, at least theoretically, change persistence strategies. What would change? Not your model objects, but your persistence tier objects. Though, again, the definition is nebulous.
3) From a Practical matter:
In many DBs, if you close the connection fromwhich
the ResultSet was derived, the ResultSet is
closed
and you get errors if you try to access it. Ifyou
don't close the connection in the Servlet beforeyour
JSP, then you have to do it in the JSP. Thatmeans
even more DB bleed through to the JSP, and theM->V.
Or, you could just not close the Connection and
d allow it to hang around and create memory
leaks.
>
Yepper.
4) Also practical:
To use the ResultSet in JSP is going to require
scriptlet code. This is ugly and hard to manageand
update later. You have to wrap your code in
try{}catch(SQLException e) {} finally {}, so
the
code is even uglier and harder to manage(especially
if you end up not touching the thing for monthsand
forget what you had done - or god forbid someoneelse
has to keep up your code). You could make acustom
tag to handle it, which makes the JSP easier toread,
but does further damage of spreading the dataaccess
code all over the application.
Definitely!
5) Practical:
When you do this sort of thing, then later
decide
to
change the way the database is set up, digging
all
the places affected by the simple renaming of a
column, or refactoring of which columns are inwhich
tables becomes a heavy effort. Keep it all in a
DataAccessObject, and changes in DB becomestrivial
to keep track of in your code. It is all in one
place, and can be tested off line. Harder stillis
if you change persistance from a database to anXML
library, or some directory lookup or something.You
would have to completely refactor your Servlet
and
your JSP. Put it in a DataAccessObject and allyou
have to do is switch out the DAO instance. The
change is transparent to the Servlet and the JSPas
long as you maintain an interface.
Just keep in mind that for the vast majority of
projects, the RDBMS technology is rarely switched.I
generally program to interfaces in my Model, butmy
Persistence tier is always so tightly coupled thatI
simply use POJO's without an interface.
6) Practical:
I have elluded to this several times, but I will
state it specifically. When you isolate the
persistance and data access to its own layer
then
you
can swap out the presentation (the View and the
Controller) when testing all your persistance
operations. This means the data is independent
of
the container. You can run it out of theServlet/JSP
environment and it will behave EXACTLY as it
will
inside the JSP environment. You can designrobust
tests, debug, redesign, re-edit, etc... muchquicker.
Then, when all done, plug it into your web app
p without worry.
Great point.
Of course, Numbers 3 -> 6 are the reasons why
following 1->2 (MVC and the 3 Tier architecture)are
such good ideas.- Saish
BTW, please take all the above just in the interest of having a good discussion. I have been wrong many times before! ;^)

JSP vs ASP

can someone here tell me the pros of using jsp against asp? benefits contras, why use one (i use jsp but i need to explain why not using others) and explain me well the reasons please

If your looking for info on a client then for
them to be a client means that they must
have sent an http request. You can use the
following jsp to get all sorts of information
about the client:
Request URI: request.getRequestURI()
Request Protocol: request.getProtocol()
Servlet path: request.getServletPath()
Path info: request.getPathInfo()
Path translated: request.getPathTranslated()
Query string: request.getQueryString()
Content length: request.getContentLength()
Content type: request.getContentType()
Server name: request.getServerName()
Server port: request.getServerPort()
Remote user: request.getRemoteUser()
Remote address: request.getRemoteAddr()
Remote host: request.getRemoteHost()
Of all of the above the request.getRemoteUser()
method is probably the one you want to use.
These methods are part of the httpservletrequest
interface under /javax/servlet/http/

Dreamweaver and Database Integration - XML. Windows 7

Hi
Looking to see where the bounds of where Dreamweaver can assist me.
I am looking to use Dreamweaver to develop a site that will need to manage the import of an xml feed from an external site to a database and then split some of the data to xslt for display and some of the other to R studio to calculate and create statistical analysis to be brought back to the website for display as calculate and graphical.
Can Dreamweaver help much with handling data and queries or is there another adobe program that will assist with that as well?
Most of the sites I create will be data intensive and while I can code websites I was looking to speed that section up to allow more time for data analysis.
Sayth

When you say Windows 7, do you mean Windows Server 2008 R2? Or are you talking about your development computer OS?
Dreamweaver is essentially an HTML editor that has website management features. The project you describe requires back-end programming with a language like PHP, RUBY or ASP.NET.
You don't mention which kind of server you are working with (Microsoft or LINUX) or what programming language you intend to work with.
You can write PHP, javascript and ASP code in the Dreamweaver code editor, and DW will do some pretty good syntax checking, but DW is not a real IDE (integrated development environment) for any language except HTML. Also, although you can edit XML in Dreamweaver, there are other environments that work with XML better.
So the short answer to your question is: yes, Dreamweaver could probably be used as your only (or primary) environment for building such a website, but that doesn't necessarily mean it's the best choice. But since you have not given us info about your server environment and programming language of choice, this is about all we can say.

Invoking Forms from JSP and Vice versa

Hi,
I am in to a requirement like invoking a screen developed using Oracle Forms 6i from JSP and vice versa.
1. Could you please anybody help to get the documents to be refered to get more idea on this?
2. Is it possible only by Oracle ADF?
Please help me on this.
Thanks & Regards
M Thiyagarajan

Hi All,
Thanks a lot for the clarifications.
Actually, integration should happen between forms and JSP. Parameters need to be passed to and forth. I will go through the specified link.
Also could you please clarify me where exactly, ADF comes into picture? or what are all the advantages when we go for ADF?
Thanks & Regards

Help with jsp and frameset

i have a dozen of asp pages which talk with MSSQL. I want to build an interactive menu with dozen of links ( probably like a tree structure with dozen nodes each pointing to these asp pages).
1) I intend to build the menu in jsp using the tree structure available.
My Question is when a user clicks on a node, i want the asp page to open in a frameset style, opening in a different frame.
this is a fragment of the jsp tag:
<ui:treeNode binding="#{Page1.treeNode1}" id="treeNode1" target="_parent" text="Tree Node 1" url="http://myserver/page1.asp">
how do i change the target attribute so that it opens the asp page in a new frame?

Build a page with 2 frames with one frame's name as say "left" and the other as "right". Assuming that you would want your menu jsp on the left, set the src of that frame to your menu jsp. and set the target as target="right" (name of your right frame) instead of _parent..

Help with jsp and servlets(litterature)

I'm planning on converting a asp website to jsp and I need to figure out the following:
1: servlet that gives out connection objects from a pool and manages "lost" connections to a mysql db
2: a bean that has getConnection and closeConnection that is used on every jsp page.
3: servlet/bean that can check size/dimesions/filetype on a remote url image
4: Figure out what users are logged in at every given moment. result: x users are on, these are user1, user2, user3. automatic removal when session runs out. probably need a servlet for this.
I got these books:
deitel java how to program 3rd edition
deitel advanced java 2 platform how to program
The last book has a servlet and jsp section ut I suspect that java has evolved since then so thats why I'm asking if you have any other suggestions that offer more than 2 chapters. Its really basic the stuff i have :)
Its been 3 years since I've touched java so i hope you guys can recomend jsp/servlet books that can answer these questions for me and help me get started with this project?
Thanks :)

1. apache dbcp commons library.
http://jakarta.apache.org/commons/dbcp/
2. tomcat DataSource, which already has the dbpc logic incorporated into it.

3. no idea, google may help
4. HttpSessionBindingListener. This allows you to monitor when a bean (such as a User bean) is added to the session and when it is removed from the session. This way you can track yourself which users are online.

Jsp and Code Behind

Is it possible to create a Jsp Page the Same way that an aspx (asp.net) Page is created.
With your basic design I.E. your html and controls in one file and then your class that extneds System.Web.UI.Page which is in you code behind file ??
if so Are there examples of this ??

Jsf is somewhat comparable to the asp.net controls yet I was asking if there is a way to do codebehind like asp.net pages.
the reason for this :;
I am converting from asp.net to jsp and want to move with the least pain.
thanks in advance
