How to transfer parameters between two iViews?

Hi all,
I have two WebDynpro based iViews (StartView and SecondView). when I press the button in the StartView, the EP will navigate to the SecondView. During this process, I want send a parameter value from the StartView to the Second View. In the StartView, I use the follow method to navigator:
WDPortalNavigation.navigateAbsolute(
 "ROLES:portal_content/com.sap.itsamtest/com.sap.secondpage",
 WDPortalNavigationMode.SHOW_INPLACE,
 (String) null,
 (String) null,
 WDPortalNavigationHistoryMode.NO_DUPLICATIONS,
 (String) null,
 (String) null,
 "value=From Start Page");
In the SecondView, I use the WDWebContextAdapter to get parameter's value.
String Name = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("value");
It works fine. But I found there is a warning message:
The method getRequestParameter(String) from the type IWDWebContextAdapter is deprecated
So is there any other good mechanism to implement the data transfer between two iViews.
Thanks and Best regards

How can I communicate between two simulated software

Hallo,
I have confusion regarding this topic "How can I communicate between two simulated software".
1: PC with CAN simulation
2: PC with AFDX Simulation
Now i have to communicated these two pc with each other.
How can i communicated? which module from ni is best for it.
thanks in advance
BR

I recommend looking at the Simple Messaging Reference Library that NI has released. Use the TCP/IP version of it.
FYI, TCP/IP is a communication protocol that is used to communicate between two computers. It is what the internet uses. So you just need a network switch or router between your computers and you can talk to each other with their IP address.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Interaction between two iViews on one page

Hi Everybody!
I have have one question and if you think I am blind, then I apologize for this.
I have two iViews on a page. The First (iView 1) is showing a Link List from KM
and the second (iView 2) is showing the content of an external link.
I would like to implement the following logic:
When the user clicks on a Link in iView 1, the content should appear in iView 2.
Can this be done with standard iView parameters or do I need to implement it on my own?
Thanks a lot and kind regards
Ingo

var design = Login {};
Stage {
title: "Main"
scene: design.getDesignScene ()
}

I'm not looking for a "tutorial created especially for me".... Just perhaps someone that can copy and paste some code from a similar project that they have done so I understand how to do it.
You could have simply put here's a tutorial for how to use TweenLite to crossfade between four pages, and here's one that will let you pass information between two .swf files. If you recently watched the tutorials then it wouldn't take long to find them (maybe you have them bookmarked) and post a couple links.
Anyways, I just found an excellent tutorial on how to crossfade using TweenLite (found here) and an article that explains how to pass information from one .swf to another (here). It took some searching and knowing exactly what I was looking for to find them, but that's a much better answer for someone looking to do those two things than I've found here (or elsewhere for that matter).

Communicate between two desktops

Can anyone lead me to a resource, or briefly describe the process, to address the scenerio below:
I have two Windows computers on a LAN. I need to develop an application for each computer that (when both computers are runing the application) allows communication between the two machines. For example: pressing a button within the application on one computer would execute a function in the application of the other computer). I am comfortable building stand-alone air apps and web-based PHP/MySQL apps with Flash/Air/Dreamweaver; however, I don't know where to start when creating a connection between two computers. Any suggestions? Thanks!

I've worked on several projects where we did this. We used a "client/server" architecture where one of the AIR apps acts as the "server" (conceptually it's the same as a web server) and the other AIR app is the "client" that connects to the server the way a web browser would talk to a web server.
For your "client" use the Socket class.
For your "server" use the ServerSocket class.
Alternatively, we also used UDP sometimes, so we'd use the DatagramSocket class on both sides (both act as "sender/receiver"). However, my recollection is that we ended up moving away from UDP since it's unreliable (by design) and switched to using TCP sockets (Socket/ServerSocket).

Communicate between two backing beans

Hi !
How can I communicate between backing beens ?
I would like to put data from Bean1 to Bean2.
This is my code in Bean1, I try this:
Bean2 b = new Bean2();
//... b settings...
//Map map = facesContext.getExternalContext().getRequestMap();
//map.put("Bean2", b);
HttpServletRequest request = (HttpServletRequest)facesContext.getExternalContext().getRequest();
request.setAttribute("Bean2", b);
So I put Bean2 instance in request, but JSF created new instance :(
How can I solve this problem ?

Dependency between two iViews

Hi all,
I have got the following problem. Maybe there is someone out there, who knows how to solve it?
I have got two WebDynpro-applications, which are bound into the portal as two webdynpro-iViews.
If one of those WebDynpros-is loaded/changed, the other WebDynpro-iView should be reloaded too.
Does anybody know to implement/customize this dependency?
Thank you in advance for your help!
Best regards, Patrick.

Hi Patrick,
You can use EPCF for this, which is also accessable from WD side. See http://help.sap.com/saphelp_nw04/helpdata/en/79/3857422d095542e10000000a1550b0/frameset.htm for details.

To communicate between two process

I have two processes running on two different machines. They have to communicate with each other by sharing messages in a peer to peer manner. What is the best possible way to achieve this. I have finalised upon using sockets, but reestablishing connections after other peer is brought down is a pain with sockets.
thanks and regards.

To exactly put it there's a GUI running on one machine and a process on other. both of these share messages. Now it must be something like bringing one down then other should not be affected it should keep buffering messages and wait for other side to come up and then start sending messages. I looked into JXTA it seemed to be a big API to work with for such a small applicaiton. It won't be a good idea to provide client with hardly some 500K of class file(or less probably) and 1.4 MB of API's. So thats why thought of writing my own communication classes which will handle this on both ends. How complicated JMS would be to work with. Does it have direct calls like register an application on some machine and then start sending and recieving messages and also take care of any of these processes being up or down.
let me know
thanks a ton for your support.

Communicate between two JInternalFrames

Hello all.
I have a swing application where I have a JFrame that encompasses two JInternalFrame's.
We'll call them AppFrame, IFrame and StatusFrame
I am attempting to create a running log of messages (Strings) that will be shown in StatusFrame.
The IFrame will be generating these messages that need to show up on StatusFrame.
Both are invoked by AppFrame.
My question is: How do I pass the message from IFrame to StatusFrame? I imagine it will involve some object sharing, but my brain is fried.
If anyone could point me in the right direction, I would appreciate it.
Thanks!

Thanks for bringing me up to speed!
Just a couple of questions...please forgive me, I am very new to homegrowing listeners.
1) When you said "which should save off the listener in some collection", how would you go about taking StatusListener listener and storing it, and, how do I access it to send a status? Do I access it by using:
listener.statusChanged("message")?
2) When you say "use the addStatusListener method of the iframe to add itself", just for clarification, I assume you mean something to the effect of:
iframe.addStatusListener(statusFrame) , right?
Again, thank you for helping me understand. I'm not quite there, but I am a lot further than I was yesterday.

Communicate between two (same) Applications

Hi there,
I've written a server application in java.
This Server is always running in the background.
For restart/shutdown or similar purpose I want to communicate with this application.
Is ist possible to start the same application with a args-flag that causes the running server to shutdown.
I know it's easy possible by doing this via the socket connection.
Because of security-reasons I want to avoid this. To limit this to the localhost is to insecure.
Any ideas?

Ok, I will explain it in detail.
I don't want to open a new Port for this,
so it is possible to use the existing open port.
The idea to limit control sequences to localhost can made by Socket.getInetAdress() (maybe insecure (fake IP)) for the existing port or via Konstruktor of ServerSocket for a new port
The point is:
I dont't want to grant access to other users on this machine!
And I don't want to limit a port for localhost from the system-enviroment via root-possibilities.
If there is no other possibility, I think I try to use a new Port for this. I just wanted to know if this is the only possibility or are there other easier ways.
Thanx for helping
