Sending parameter between JSP and CGI

How to send parameters from CGI to JSP ? And how to receive returned value from JSP to CGI?

When you mention "rest of params" as a parameter, would the request not include all of the parameters within that bean????
You might be calling ur bean from the JSP right, for
eg assume your bean name is "myBean".
From JSP you pass the request object ie,
myBean.executeTransaction(request,<rest of the
params you need>)Your bean should be like
import javax.servlet.*;
//methods
public String executeTransaction(HttpServletRequest
request, <rest of the paramss){
//do you check here
//if request.getParameter("actionPerformed")==null(?)

Troubles of transfering parameter between jsp and flash

I have a problem in programming. I can't actualize the
parameter's transfer from a jsp file to my flash. It could run
normally when I first design this program some weeks ago. But now,
it can't work! I don't know why.
My flash player's edition is 7. The flash code is :
var id;
var flash;
_root.onLoad = function() {
loadVariables("
http://localhost/exonline/flashtest/jspfile/flash.jsp","_root","POST");
_root.onData = function(result) {
_root.reply_clientData = id + flash;
The jsp code is:
out.println("&id=this is flashid from
session&&flash=flashfilename &");
I have completed the security settings following the
instruction on the web that always allow and adding the flash file
into trust fields, but it still don't work. Who can help me? Thank
you very much!

Is there anybody can help me?

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.

Communication between jsp and abstractportalcomponent

Hello All
Communication between jsp and abstractPortalComponent.
jsp contains one input text field and one submit button.
when the user clicks on submit button it will call the component and that input value will
display in same jsp page.
how this communication will happen?
Rgrds
Sri

Hi Srikanth,
In the JAVA File,
OnSubmit Event,
String inputvalue ;
InputField myInputField = (InputField) getComponentByName("Input_Field_ID");
if (myInputField != null) {
               inputvalue = myInputField.getValueAsDataType().toString();
request.putValue("textvalue", inputvalue);
request is IPORTALCOMPONENTREQUEST Object.
In JSP File,   to retreive the value,
<%
String textstring = (String) ComponentRequest.getValue("textvalue");
%>
In PORTALAPP.XML File,
<component name="component name">
      <component-config>
        <property name="ClassName" value="classname"/>
        <property name="SafetyLevel" value="no_safety"/>
      </component-config>
      <component-profile>
        <property name="tagLib" value="/SERVICE/htmlb/taglib/htmlb.tld"/>
      </component-profile>
    </component>
Using the code above, You can pass and read values between abstract portal component and Jsp Page.
Instead of this, I suggest you to use JSPDYNPAGE Component for Data Exchange.

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)

How to deliver variable between jsp and EL ?

this is the code of my *.jsp
<%
int g_nAge=12;
%>
${g_nAge}
I suppose that "12" is showed in my web-page,but actually I see nothing.
This is an example in my jsp book showing the delivering variable between JSP and EL !
how can it do that ?

EL cannot pick up scripting variables. It picks up attributes from scope only.
Similarly it doesnt set any scripting variables too.
<%
int g_nAge=12;
pageContext.setAttribute ("g_nAge", new Integer(g_nAge));
%>
${g_nAge}cheers,
ram.

Difference between JSP and JSF

What is the difference between JSP and JSF?
Is it necessary to learn JSP before starting with JSF?

JSP is a view technology providing a template to write plain HTML/CSS/JS in. JSP supports Java based taglibs to generate output and/or control the page flow dynamically. A well known example is JSTL. JSP also supports access to backend data with help of EL (Expression Language).
JSF is a component based MVC framework which provides taglibs for use in JSP, the JSF core tags in <f:xxx> and the JSF HTML tags in <h:xxx>. Those tags generate HTML output and are tied to JSF component tree in the server memory so that the FacesServlet can work on them to gather request parameters, validate/convert them, update the model values (javabean properties), invoke some actions (javabean action methods) and render the response.
You can use JSF on top of either JSP or Facelets. Facelets is another view technology. JSP is ancient and has its shortcomings when JSF comes into picture. Facelets is designed with JSF in mind and much more well-suited for it and provides great templating/composition capabilities to reuse specific groups of components without the need to wrap them in another custom component (so that you don't duplicate the same code over and over, e.g. label+input+message.

Passing values between jsp and php

hi there, is it possible to pass values between jsp and
php? i really need to find out the way if there is
any. thanks in advance
-azali-

Yes, there are a few ways to do this.
1) Think about using Cookies.
2) Maybe use a Redirect passing the values in the Query string.
3) Retain the data in a repository in the back end.
4) Using Hidden fields within your pages.
I am sure you can use these Idea's for a base to develop other methods on how to pass values back and forth from JSP -> PHP and vice versa.

Passing session data between jsp and servlet

I have a servlet that I pass data to my jsp.
I do a session.setAtrribute in the servlet. No problem.
I get the data no problem in the jsp that I call.
How do I pass this same data to the another servlet?
I basically have an array of values that I already have in the existing jsp that has been set in session.
When I call the secondary servlet, I don't have anything in this session variable related to my array.
Prior to posting to my next servlet, do I need to do another setAttribute inside the jsp to get the data passed to the servlet?
Thanks.

Two different things. The encoding adds this to the URL (after the page, before the query string
;jsessionid=ABC123 but only if the user isn't using cookies.
So in your example, you would do this (maybe):
<%
String url = response.encodeURL("Servlet");
%>
<form name="form1" method="post" action="<%= url %>?cmd=pay"> ... Or some modification.
So the difference between encodeing and using a post is that
1) encoding adds the jsessionid to the url string if necessary. It does nothing else
2) POSTing will send a request to the provided URL via the POST method, including the inputs of the form as parameters to the URL.
They really don't interact with each other. It is like asking what is the difference between the Color Orange and thr Size Big? They can both be applied to the same thing, or not... and have no real relation to each other.

Whats the difference between *.jsp and *.jspx

Hi
When I create a new jsf page the first step prompts me for the "type". I am wondering what is the difference between JSP Page and JSP Document? Which should I be using? Are there any white papers or documents that explain the advantages of each?
Also, someone suggested that I use Facelets, has anyone else used these from inside jdeveloper? Any thoughts / tips would be appreciated.
Thanks
troy

JSPX uses an XML doument for you page code - it is the way we recommend you build your page. Makes for cleaner code and easier customization.
JSP uses HTML with embedded JSF tags in it.

RFC Sender problem between 46D and RFC adapter

Hi,
I have this simple integration scenario where I want to send data to a archiving system;
SAP -> (tRFC) -> XI -> (MQ) -> BizTalk -> (MQ) Arch.syst.
SAP side ***
A Z-program using a Z func. like;
    CALL FUNCTION 'ZSD_DCF_SEND_TAG'
      IN BACKGROUND TASK
      DESTINATION 'XISYSTEM_TRFC_DCF'
      EXPORTING
        pt_filing_info = gt_filing.
    COMMIT WORK AND WAIT.
XI side ***
Both IR and ID is configured correctly, in the development environment everything works just great. I have created a test program where I can define how many calls I will do, looping over the func. call with a commit inside the loop - 500 or more msgs are ok.
The integration scenario is transported to quality enviroment using CMS, and the RFC sender comm.ch. is configured accordingly.
The problem in quality ***
When sending just 1 msg, everything is just fine, message received and delivered to MQ.
When sending >= 2 msgs, the 1 msg is always ok, BUT all others fails due to the following from Adapter monitor;
RFC_HISTORY
- Error: 2006-01-19 10:55:18 CET: com.sap.aii.af.rfc.afcommunication.RfcAFWException: lookup of alternativeServiceIdentifier via CPA-cache failed for channel 'RFCSender_XI0002' (02d4d30de3593874942ed0659add0827, party '', schema 'TechnicalSystem', identifier 'Q93#120')
- OK: 2006-01-19 10:55:17 CET: Message processed for interface ZSD_DCF_SEND_TAG
My sending system is Q93 CLI 505 so I can understand the error, BUT I cannot understand why the RFC adapter is saying the TechnicalSystem is Q93#120 - it should be Q93#505. My Q XI has client 120...
It seems to me that the RFC adapter is kind of confused about the sender..
I have created a OSS message and SAP has looged on and looked into it with both a XI expert and RFC expert without being able to answer - all is configured correctly.
- The SLD config. for bus.system Q93 is ok -
- The bus.system in ID is showing correct vaues for
Adapter Specific Identifiers (SID Q93, client 505)
- Both Dev. and Qual. environment are running on XI 3.0 SP 14 latest patch, RFC component version on the SAP side is identical between dev. and qual. SAP systems
- It doesn't matter which gw I use (Q93 gw or XI gw), the error is persistent
- It doesn't matter if I increase initial conn, max conn.
I have also tried to use qRFC instead, but with the same result.
Anyone using tRFC for asynch. communication from SAP to XI seeing something similar?
Meanwhile, I will do RFC trace on GW and RFC Adapter on AE....
Please, do not say SP15, oss msg for FAQ RFC adapter or links to RFCAdapter config....
best regards
Torstein

Hi,
SAP Note 730870 FAQ: XI 3.0 RfcAdapter Q.no 15
<i>Q 15: Whats wrong when the error message "lookup of alternativeServiceIdentifier via CPA-cache failed" shows up while sending a RFC call to the RfcAdapter?
A: A RFC sender channel is located beneath a service within the Integration Directory. Within this service choose "Service" -> "Adapter-Specific Identifiers". The values in the fields "R/3 System ID" and "Client" has to be maintained with the correct values of the system, that sends the RFC call to the RfcAdapter. It normaly only makes sense to have these values filled for services of type "Business System". If maintained in SLD, this fields will be filled automaticaly for services of type "Business System" and can be updated with the button "Compare with System Landscape Directory".</i>
- Give correct appserver and gateway service details in XI.
- Open the service holding the RFC adapter you are trying to use. On the top menu, goto Service -> Adapter Specific Identifiers..

Prateek

What's the difference between *.JSP and *.DO?

Hi. I'm new to JSP programming and noticed that form actions call something like pageName.do -- what's the difference between the .JSP and .DO? When do you call one vs. the other? Thanks.

A request including the jsp extension usually refers to a single JSP file on disk that will be loaded and rendered directly.
A request including the do extension usually refers to a call into a special servlet that will redirect the request to another "controller" class which will in turn do some processing, and then load one or more JSP files to render the response.
The commonest form of the latter is the usage in the Struts framework. The do extension is not mandatory, it just presents a convenient way to distinguish calls that should be handled by Struts from requests for JSPs and other content that are mostly handled by the container (e.g. Tomcat) directly.

Jsf passing parameter between jsp's

Hi
I have my main.jsp and another screen which i call object.jsp
the object.jsp can present an object in multiple ways : add, edit, view
i have 3 buttons in my main.jsp add, edit, view. I want to pass a parameter from main.jsp to object.jsp such that object.jsp will know in what state its being loaded... how do i do this?
Thanks..

session?
as the article says :
To avoid these problems, developers might use session-scoped variables instead. This fixes both of those problems, but adds new ones:
A single user cannot have two windows open simultaneously; session-scoped variables are global to the user. So, for instance, a user could not work with two different search results simultaneously.
Back button support is highly limited, since navigating back can't magically restore the session to its old state.

Passing parameter between JSP

Hi All,
I want to pass a parameter (let us say data from a text box) from one JSP to another on an event (when 'Submit' button is clicked.). Can you please let me know how to go about this? Any sample codes or any other kind of help will be greatly appriciated.
Thanks in advance.

hi,
It's quite easy, just go thru the following code.
one.jsp
<form action="two.jsp" method="post">
<input type="text" name="name"/>
<input type="submit" value="Press"/>
</form>now receive the value in two.jsp and print the same.
two.jsp
<%
String name=request.getParameter("name");
out.print("Your Name -->"+name);
%>Bala
