Muliple process interactions with client

Is it possible to have multiple interactions with the client?
I have a BPEL process that calls a web service and then replies to the user what is sent back. This is then used by the user to invoke another web service through the business process.
In other words: the client initiates the process, the process uses this to invoke a service. The reply is sent to the user. The user then sends another message to the process which uses this to invoke another service. The result of the service invocation is sent to the user by the process.
This seems really simple but I am having trouble achieving this and all examples seem to be one invocation by the client and then one repliy. If anyone knows if/how this can be achieved it would be greatly appreciated.
thanks,
Clive

yes, its pretty much possible to call the same BPEL instance again and again. This is called Asynchronous call back, and is possible with WS-Addressing or you can use the BPEL Correlation set to achieve this functionality.
Here is a step by step tutorial on how to achieve this,

Web interaction with client application

Hi all,
I have self taught myself Java over the last 4 years on and off.
I am in the mid stages of developing an MRPII application with various modules. These modules are effectively JTabbedPanes within JInternalFrames. The JInternalPanes are within a JDesktopPane which also has JTabbedPanes.
This enables me to have departmental tabs at the top of my app and module functions at the left hand side, dependant of which departmental tab is selected.
I have created a class that connects to MySql and can do various functions which I then can derive specific MRPII classes.
I have a desktop PC which I have MySql configured as a server and a laptop which is configured as a client. Both machines run WindowsXP and my router is a linksys.
With this setup both machines can check inventory, take orders, produce purchase orders, create customers & vendors etc....
My next step is to try and incorporate a web component into this.
My ideal goal is to have a database that is set up and hosted on the web and works in the same way as my home network. This would enable me to deploy this application and configure the ODBC data source to point to an IP address. Is this possible and if so how would I go about it.
The other option is to create web pages with forms that interact with my local server. If this is the better option, I am unsure whether I should learn about servlets or possibly XML, as all I have learned so far is about applications.
Your guidance would be greatly appreciated.
thanks
Jim.

I wouldn't let client applications connect to a database directly. What if you make a change to the database in order to fix a bug for example, that would mean rebuilding the clients and redistributing them and in the mean time any old client is most likely broken.
I would let the server communicatie with the database locally and expose either an XML-RPC or a SOAP connection to clients. This makes your framework extendible and abstract, all you do is implement SOAP methods on the server that your clients will invoke. As long as the response of such a call never changes you do not need to change your clients. And who knows, you may even use additional data sources (other databases for example) on your server, your clients will never have to know about it.
If you want to learn about SOAP, check out Apache axis.

How to authenticate BPEL process to a PL with Client SSL Cerificate

Hi,
I need to invoke a partner link which requires authentication with Client SSL certificate. So, here is the use case:
- The PL's endpoint is https://some.server.com/web_service;
- I have a client SSL certificate supplied by the web service provider in the form of PKCS12 (PFX) file. I should use this certificate for authentication.
I read carefully the BPEL Administration Guide, the part about SSL authentication (http://download.oracle.com/docs/cd/B31017_01/integrate.1013/b28982/security.htm#CHDHIBEG), but in this guide is described how outer services can be authenticated by the BPEL Process Manager with client SSL certificates, not the vice versa.
So, I completed the following tasks:
- I imported the server certificate of https://some.server.com/web_service into $ORACLE_HOME/jdk/jre/lib/security/cacerts file;
- since I didn't find a way to import the client certificate as a PFX file, I converted it PEM file, using OpenSSL utilities and manage to import in cacerts client certificate's public key, but not the private key. Of course this didn't help me in any way to get authenticated.
I would appreciate any help on this topic!
Thank you!
Simeon

i get this action plan and works for me...
1. Download the new Client Certificate.
2. Convert the Client PFX to JKS as per:
http://www.cb1inc.com/2007/04/30/converting-pfx-certificates-to-java-keystores
3. Using firefox go to the WSDL site:
* Add the exception, if Firefox ask for it.
* Import the server certificate to Firefox following the instructions displayed
4. Once you imported the certificate on Firefox, go to:
* Tools -> Options
* Select Advanced and click on "Encryption" tab
* Click on View Certificates
* Go to the Servers tab
* Select the "servercfa" and click on "Export"
* Save the certificate adding the .cer extention to the name.
* Ensure that you select in Save as Type "X.509 Certificate with Chain (PEM)"
5. Import using keytool the exported certificate from step 4 to the JKS obtained in step
2:
* i.e: keytool -import -alias servercert -file servercfa.crt -keystore client.jks -storepass welcome1
6. Add both keyStore and trustStore properties to the jdev.conf pointing to the same JKS :
AddVMOption -Djavax.net.ssl.keyStore=C:\jdevstudio10133\jdk\jre\lib\security\client.jks
AddVMOption -Djavax.net.ssl.keyStorePassword=welcome1
AddVMOption -Djavax.net.ssl.keyStoreType=JKS
AddVMOption -Djavax.net.ssl.trustStoreType=JKS
AddVMOption -Djavax.net.ssl.trustStore=C:\jdevstudio10133\jdk\jre\lib\security\client.jks
AddVMOption -Djavax.net.ssl.trustStorePassword=welcome1
7. Open Jdev and retest the issue.

How Client interact with Server in regular interval

Hi friends,'
I want to develop a chat server where the user should sent the request to server in background(as server can not sent response unless the request appears).So on regular request from the Client the server check the updation in database and sent the correspong message to user.
How can i do this where the Client should interact with server in regular interval?
Is there any other way to accomplish this ,any reference guide /tutorial to develop this ?
Regards,
Sachin Warang.

You could add an <meta http-equiv="refresh" content="5;http://yourhost/context/servlet/"> to the HTML which will refresh the page every 5 seconds (change the 5 to 10 for every 10 seconds, etc.). The other way is to set up a JavaScript timer and use an XmlHttpRequest to make an asynchronous call to the server and update the HTML dynamically (using DOM) when a response is received (AJAX). Lastly, you could implement the client as an Applet, which gives you a much richer feature set and is a lot cleaner (having half of your app in JavaScript/DHTML is kind of messy).
There are some vendors, such as IceSoft (http://www.icesoft.com/) producing JSF components that do the AJAX stuff transparently, so you just code a normal JSF app using their components and wire up to bean action methods where you need to.

Interact with extern process by Runtime.exec()

Hi,
I want interact with a extern process by Runtime.exec(), but I don't Know the way for introduce the params required for the extern process.
So, Is posible, interact with the extern process from Java?
Thanks

Exactly, I would like to know how exec can pass a PIN
number when the proccess already has been launched. Sounds like you're doing it through the process' stdin. Read that article I linked.
You'll have to call Process.getOutputStream() or whatever that method is. To you it's an OutputStream, to the process, it's input. You'll write the stuff to that stream that you'd type to the command line. If you want to get that from the user interactively, you'll do it like you would any interactive user input in any Java program--get it by reading System.in or from some GUI element, and then take that and write it to the process' stream.
If you're not familiar with I/O in Java, look here:

Math Interface Toolkit in Matlab: Can I interact with a VI as a parallel process

I'm curious if it's possible to create a Matlab MEX file using the LabVIEW Math Interface Toolkit (MIT) that can be called in matlab and accessed while running?
I'd like it to effectively work just like any other object in matlab. I'd like to be able to query the object while it's running, dump values out of a buffer, and even hook events if possible.
As it currently stands, the VI to MEX setup seems to just allow me to call a VI, run it, and then drop out. I want to be able to continuously acquire and access the data as it's coming in and interact with it from matlab (i.e. fully integrate the VI into my matlab code as a separate object).
Is this possible in some form or am I stuck with dedicating the matlab interface to the VI whenever I want to call it?
Thanks

Hi GusLott,
You are correct that when you call a VI the command line will not continue until the output is obtained. This makes sense since in LabVIEW that is how a VI operates (a subVI does not ouput until all outputs are obtained). I believe this is also how commands in MATLAB work as well (correct me if I am wrong). On the otherhand this is not a disadvantage in labVIEW since you can run VIs in parallel. If you can create some way to run parallel threads in MATLAB then you will be able to do two (or more) MEX calls at once.
As far as object oriented programming goes, there is a labVIEW OOP, but I do not think it has been tested in conjuction with the Math Interface Toolkit.

Interact with another process

Does anyone know how can I make my program send/read text from another program? Let's say that my active window is Notepad. I would like to be able to insert text and also read what has been typed (i.e. it would copy & paste).
Any macro program can do that, but I want to treat the data with Java.
Thanks.

If what you want is just a copy&paste tool wich can interact with other programs, you can try the api clipboard from awt:
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.ClipboardOwner;
import java.awt.datatransfer.Transferable;
import java.awt.datatransfer.StringSelection;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.UnsupportedFlavorException;
import java.awt.Toolkit;
it can be useful:
// clipboard
public void getClipboardContents() throws Exception
     BufferedReader in;
     Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
     Transferable contents = clipboard.getContents(null);
     boolean hasTransferableText =(contents != null) && contents.isDataFlavorSupported(DataFlavor.stringFlavor);
     if ( hasTransferableText )
          in = new BufferedReader (new StringReader((String)contents.getTransferData(DataFlavor.stringFlavor)));
          String linea = in.readLine();
          while (linea!=null)
               linea = in.readLine();
          in.close();
public void setClipboardContents( String aString )
     StringSelection stringSelection = new StringSelection( aString );
     Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
     clipboard.setContents( stringSelection, this );
the clipboard can be fullfilled from any app and read from java because it's a sysyem pool, but you cannot receive events from windows apps like notepad, you can copy notepad's text and paste it to your java app.

Interact with web site

I'm programming a chatbot that will be able to get information from web site if it isnt in the script. Im at the stage where I want to use a web site's search engine, namely www.imdb.com/search to continue. The idea is I will send the search term on java program, the program connect to the web site, uses the search engine on the site and get the resulting web page. The program get the html code, process it and exact whatever user want to know.
Problem: I have no idea how to make a program that will be able connect to imdb, to do a search on imdb's search engine and get the html for further process. Can anyone advice me on how to interact with their's search engine and get the result?
The code i got so far can only exact the html code, however this will not work because imdb connection refuse.
     URL yahoo=new URL("http://www.imdb.com/");
     BufferedReader in = new BufferedReader( new InputStreamReader (yahoo.openStream()));
     String inputLine;
     while ((inputLine=in.readLine())!=null)
          System.out.println(inputLine);
          in.close();
          }

Thank for the direction and tips. Now I have more understanding of what I needed to do. However, I still cant come up with an solution for what I needed to do. I read the wiki page on
HttpClientPowered A list of applications that use HttpClient
Client HTTP Programming Primer
What I need to do is to use those API to perform search and get the resulting html code, with my limited understand of both Java and web technology, I can find which method I need to perform a search and get the resulting html code.
Can anyone give me more details please, I need to decide what I need to do within a week depend on if I can make that part of the program.
Thank
Also I tried some of those example code, I cant make them run cause im missing org/apache/commons/logging/LogFactory, cant find it on the download section. Im thinking of getting the html code from .Net now...can you show me what is the code to do it in .Net please? I know nothing in .Net btw.

Can Director Interact With Other Applications?

Hello,
I am a CBT/E-Learning Developer looking for a way to author
Guided Help. I am thinking of how to develop interactive tutorials
that, instead of using screenshots of an application, interact with
the application itself.
For instance, let's imagine that a person is working in MS
Word and doesn't know how to save a file. He can click the icon for
the "Saving A File" lesson, and a caption displays on top of MS
Word that reads something like "Click FILE", along with some type
of indicator of the FILE button, such as an outline, highlight,
arrow, etc. The user clicks FILE, the File Menu drops down in MS
Word, and the next step of instructions is displayed. In this way,
the usre is guided through the steps of saving a file as he
actually performs the task in the software.
Can Director create this type of thing?
Thanks a lot,
Mike

Hi Chunick,
Thanks for replying. I used MS Word as just an example; the
type of software I'm wanting to use this for is police records
management software. I've been doing the interactive simulation
tutorials for them since 1999, using multimedia authoring tools
Demoshield and Opus Pro, and demo authoring tools RoboDemo and Demo
Builder. However, I wanted to get away from interactive tutorials
for 3 reasons:
(1) My client's software is frequently updated, and keeping
up with taking new screenshots is a hassle.
(2) I'm of the opinion that "at the moment of need", process
embedded "guided help" in the actual application is a much more
useful form of training than working through a simulation.
(3) It will greatly help my client's support staff and
training staff
I've been researching process embedded e-learning and guided
help for almost a year now. I've looked at everything from
multimedia authoring to macro software. I even found two programs
that do exactly what I want, but they are very very expensive, much
more expensive than Director.
Thanks for the tip on Hook Xtra; I'll check that out. Last
night I found an xtra called MasterApp, which may also do what I
need. I appreciate the concern about the difficulty of programming,
and I'm not a programmer (except HTML, and we all know how easy
that is). But I'm in this for the long haul, and would be using it
for potential new clients, not just my current client. I love
learning new software, and I have a membership to the IEEE Computer
Society, which gives me over 1300 online e-learning courses I can
take, including Director.
Thanks again for the lead!
Mike
