Communication between servlet(client behavior) and stand alone java program

Hello all:
I need to send a message (ascii characters sequence) from a servlet to a java program, but I'm not sure what is the best way to get it: socket, JMS or other mechanism that I don't know.
Is the servlet who is operating how client behavior.
Please, any comment will be appreciated, regards,
Ulises.

You can always start a ServerSocket on the client (kinda sounds funny, doesn't it) which will accept connections. You then open a plain old Socket on the server to connect to the client's listener. (Note, this is the reverse of a normal set-up). Once you have the connection established, you will call getOutputStream() to get a stream to write to. Likewise, you will call getInputStream() to read the data sent. You will want to investigate the java.net.* and java.io.* libraries.

Diff was java add in and stand alone java instance

Hi Guys ,
What is the diff between was java add in and stand alone java instance ?
Thanks
Sonam

Hai,
SCS is nothing but the SAP Central Services, it is AS Java instance of an SAP system containing the enqueue server and the message server.
JAVA Addin is inserted in exsisting ABAP only instance to have JAVA functionality. JAVA instance is assigned to an ABAP instance. The Internet Communication Manager (ICM) of the ABAP instance starts and stops the associated Java instance as required.
Netweaver JAVA (Stand alone) vs JAVA Addin:
Netweaver JAVA Addin installation is a dual installation that consists of Java and ABAP stack. Addin is required when you are implementing SAP XI (Exchange Infrastructure). Stand alone JAVA is required when you implement SAP EP (Enterprise Portal). It is generally not recommended to use dual installation for EP because this will expose the ABAP layer to the public Internet. So the ABAP stack is often used to host SAP ERP ECC (Enterprise Central Component), SAP CRM, SAP SCM, etc.,
Since the information hosted on ABAP stack is more sensitive in nature you are recommended to install Portal on the Netweaver AS Java server (Stand alone JAVA server).
By doing this you will be able to fully utilize the system resources for the portal and ensure good performance.

Problem while calling a Webservice from a Stand alone java program

Hello Everyone,
I am using a java program to call a webservice as follows. For this I have generated the client proxy definition for Stand alone proxy using NWDS.
Now when I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
public class ZMATRDESCProxyClient {
     public static void main(String[] args) throws Exception {
          Z_MATRDESC_WSDService ws = new Z_MATRDESC_WSDServiceImpl();
          Z_MATRDESC_WSD port = (Z_MATRDESC_WSD)ws.getLogicalPort("Z_MATRDESC_WSDSoapBinding",Z_MATRDESC_WSD.class);
          String res = port.zXiTestGetMatrDesc("ABCD134");
          System.out.print(res);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>Material Not Found</b> -
> This is the output of webservice method and it is right.
Can any one please let me know why I am getting the warning and error message and how can I fix this.
Thanks

Hi Abinash,
I have the same problem. Have you solve that problem?
I am using a java program to call a webservice too. And I have generated the client proxy definition for Stand alone proxy using NWDS. When I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
MIDadosPessoaisSyncService service = new MIDadosPessoaisSyncServiceImpl();
MIDadosPessoaisSync port = service.getLogicalPort("MIDadosPessoaisSyncPort");
port._setProperty("javax.xml.rpc.security.auth.username","xpto");
port._setProperty("javax.xml.rpc.security.auth.password","xpto");
String out = port.MIDadosPessoaisSync("xpto", "xpto");
System.out.println(out);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>The result of the WS is correct!!!</b>
The Java project does not have any warning. But the stand alone proxy project has following warnings associated with it.
This method has a constructor name     MIDadosPessoaisSync.java
The import javax.xml.rpc.holders is never used     MIDadosPessoaisSyncBindingStub.java
The import javax.xml.rpc.encoding is never used     MIDadosPessoaisSyncBindingStub.java
The constructor BaseRuntimeException(ResourceAccessor, String, Throwable) is deprecated     MIDadosPessoaisSyncBindingStub.java
It is very similar with your problem, could you help me?
Thanks

Error 2032 in communication between Flex Client and WCF

Hi All,
I'm trying to establish communication between Flex Client
and WCF service.
WCF service accepts gZip compressed data and returns gZip
compressed results.
So I used Flex ByteArray.compress() and
ByteArray.uncompress() for this purpose. However, it throws error
2032.
The gZip compression/decompression uses MemoryStream class in
C#. Based on my previous experience, memory stream communication
between Flex and C# gives erro 2032.
Is there a work around for this?
Thanks,
Vishal

I read some thread in the forum, and found somebody had the similar problem with me. Just want to know how to settle this problem.
In the client/server program. Client is a JAVA program and Server a
VC++ program. The connection works, and the problem appears after some time. The Client sends a lots of requests to Serverm, the server seems receive nothing. But at the same time, the server is able to send messages to Client. The Client also can get the messages and handle them. Don't understand why there this problem and why it appears when it wants.
The client is a Win2k platorm with JDK1.3.1 and the server is also a Win2K platform with VC++ 6.0.
In the Client, using:
inputFromServer = new BufferedReader(new InputStreamReader(socket.getInputStream()));
outputToServer = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
Hope can get your help.

Can I backup between a testversion and stand-alone version?

Can I backup between a testversion and stand-alone version?

You are correct, the CC version is activated with your Adobe ID and password after you have signed up for the creative cloud plan. You can uninstall that CC version and install the standalone. It is the same program, and will open the same catalog. You don't need to back up anything. Just change over to the standalone program and start Lightroom. Everything will function just the same6.

Communication between two clients

In Java Networking, communication between server-client or bwtween server-multiple clients is general. But How will be the communication between two cients, means two clients can send & receive messages to & from each other(being guided by server).

Sorry,
I didn't get your reply clearly.
I want, if Server is running, and two clients(two instance of a same program) are opened, whatever message(string)client1 send to Server,then the Server needs to send those to client2.Again, the some response should come from client2 to client1 thru Server.
How can I implement this?
If you have idea, or some sample code about this, please let me know.
Regards.

You didn't post the stack trace from the server, but I'm guessing it's complaining about the QName class. Sun changed the QName class in JDK 1.5 wreaking havoc on JDK 1.5 clients that use JDK 1.4 servers and attempt to pass a QName object from one to the other. If your client uses JDK 1.5, your sever will need to use a QName class which is compatible. The file liquiddata/lib/wls90interop.jar contains a QName class that is compatible with the one in JDK1.5. You can put it first in the classpath of your server.
If you already have wls90interop.jar first in the classpath of your server, then, for your client, you need to either (1) use the Sun JDK 1.5; or (2) put wls90interop.jar first in the classpath of your client (if you are running JDK 1.4).

Communication between PC/RM Backend and ERP System

Hi,
Is it possible to have communication between PC/RM Backend and ERP System by cresting RFCUSER with user type communications data instead of Dialog user.
Because of audit policy , none of DIALOG user should have SAP_ALL profile.
Is there a option to set up communications between PC/RM Backend and ERP System without a Dialog user setting.
Pravin

Hi Pravin,
You are right and the user should be always communication or system. GRC AC allows for the user to be communication or system. Can you try with PC/RM RFC user and see if it works? It should work

How do I set my firewall settings in Avasti to allow communications between my HP 8600 and my comput

How do I set my firewall settings in Avasti to allow communications between my HP 8600 and my computer

Something to Consider:
If you are talking about "Avast!" Security Software, either the free or the paid version, the following may apply to you:
There are three main levels of Security in the Avast! software: Home, Work, and Public
Home is the setting many people use when "at home", that is, connected to the home network. The home network is sometimes defined as the "192.168" network: these are the computers and printers that you have and use in your home environment. The network is (most usually) private and (should be) secured with with a passphrase at your router. The Avast! Software sees the "Home" network as a "safe" environment: devices connected within the "Home" network are allowed to "talk" (communicate) with one another without undue restrictions.
Work is the next setting. The software places some restrictions on this level of communication. Home users can certainly use this setting -- in many (most) cases, the "Work" setting is a solution that provides for communication and a bit more security for the home network and its devices.
Public is the strictest setting and is meant to keep your computer safe in a public place: the library, coffee shop, on a street corner. Outside "prying eyes" are prevented from peeping and outside communications are restricted.
If you have set (or left) your Avast! software set to Public, or even Work (and you do not know how to handle the restrictions), then you may have simply locked out the communication between the printer and the computer(s) on your home network.
Open your Avast! Software and set the security level to either "Home" or "Work".
You can find out more about how to use the software settings at the Avast! website.
Advanced Users Only - You will know if you changed the Rules... this is not something one does by accident.
If you have changed the rules within the settings, you may have locked yourself out. Make sure you have both "in" and "out" traffic settings adjusted correctly for each rule you change / adapt / add.
Kind Regards,
Dragon-Fur

Email links out of Practice Fusion are not active (as they are in IE), which they say is a problem with "something lost in the communication between the Flash engine and the browser". Does anyone have experience with this?

This is a medical records system, cloud based. I use Firefox to get into the system, but any browser would work. Other than this problem, Firefox works fine (better than IE, in my opinion).
Patient demographics include their email, which is hyperlinked and should go right to Outlook (my default email program). This works in IE, but nothing happens on the click when using Firefox as the browser.
I queried Practice Fusion, which replied: In regards to your previous question about the email hyperlink in the patient information, it looks this is not something that can be fixed on our end right now. It is the web browsers' responsibility to handle these types of links, and there seems to be something lost in the communication between the Flash engine and the browser. I apologize for any inconvenience.
Thanks for any help anyone can provide.

See if this helps you:

Encrypt communication between SharePoint Web App and SSRS

Hi
I have SharePoint 2010 in multi server farm. The SharePoint web app has SSL enabled. The Reporting Server (SSRS) is http URL.
So when the Report Viewer web part is used, the communication between SharePoint web server and SharePoint Reporting Server is unsecured. The existing SSL has hard coded hostnames and for business reasons we prefer not to modify it.
Does anyone know how can I make that communication secured? Do I need to apply new SSL for SP Reporting Services? Is there any other option?

This should get you off and running on SSL

and if you haven't go SQL on SSL - ->

Differences between Remote Client copy and Client export and Import

Dear All, I am new to SAP. Please let me know the Differences between Remote Client copy and Client export and Import. Any response is greatly appreciated. Thanks a Million

Hello Mallikarjuna,
Follow the below note,
https://service.sap.com/sap/support/notes/552711
which describes the answer to question - Which is better or faster, a client transport or a remote copy?
Basically client transport would be preferred if the network connection between the source and target system is slow.

which profile allows communication between iOS 4/later and Bluetooth Health Monitor(such as Fetal Heart Rate/Motion/respiration etc. )

Thank you!
We are developing a monitor with Bluetooth 4.0 moudle, also programing an iOS App for this wireless monitor. We want to transfer the monitor data to iphone/ipad(which installed the App) through bluetooth.
As you know, many bluetooth device are not allowed to connect to iphone/ipad through bluetooth. So I'd like to know that which of the iOS supported bluetooth profies should I use when programing, to ensure the monitor can connect to the Apple device and upload data. Of course, if they can connect successfully, both of the monitor and Apple device would be acknowledged "connected".
