Hi Vincent,
          I had alreadry referred the Note:353597 and created the RFC connection for program "RSLSAGDS" but while testing the connection it shows the following error:

JCO.Server Error while trying to execute a RFC program from SAP

Hi,
We are connecting to an external registered server program from SAP via Web Methods.
The external server program is registered with the SAP Gateway. We have created a TCP/IP RFC destination and are able to connect to the destination successfully via SM59.
An RFC function is created in SAP and is called using the syntax CALL FUNCTION "/NGN/BAPI_STRE_SEARCH_PROCESS" DESTINATION 'PRDB2B'. We have also handled the COMM_FALIURE and SYSTEM_FALIURE exceptions in the function call.
We are monitoring the gateway via SMGW and see a connection log to the RFC destination as below
Number - 10
LUname - dev01
TPName - sapgw00
User - KRAORANE
Status - CONNECTED
Symbolic - PRDB2B
Conversation - 86520353
Prot - REG
SAP return code - 0
CPIC rtn code - 0
The external program returns results as expected.
However sometimes the RFC fails and returns the message JCO.Server could not create server function /NGN/BAPI_STRE_SEARCH_PROCESS.
We are not able to figure what exactly is causing this error. Any help will be highly appreciated.

JCo server programming, properties and connection settings

Greetings, SAP professionals.
The reason I come to this forum is that I'm hoping to gain some insights into the use of the SAP Java Connector (JCo). I am a developer who was tasked with making a new component for a systems integration application. As is typical of integration software, our app can link together various different systems using a variety of protocols, as well as providing the means to apply business logic on messages passed from one location to another. We already have a connector acting as an SAP client which was implemented using JCo. Now, we were asked to develop a new component: a server capable of accepting RFCs from a remote SAP system acting as client. The server is to be created using the JCo classes, so basically an extension of JCo.Server, with some logic for creating function templates from configuration files.
However, while I'm understanding the structure of the Java API, it's not entirely clear to me just what the classes do. I've found the JavaDoc for JCo to be mostly descriptive of the interface of classes and methods, but not really explaining what these achieve, or how. So I'm hoping to be set straight, as I fear I'm kind of misunderstanding the functionality of JCo... Being mainly an integrations developer, I unfortunately often have to settle for gaining a superficial knowledge of a variety of systems to quickly interface with them, so I don't have any prior knowledge of SAP but still need to be able to implement something with JCo without too much delay.
The most important question I have is this: when a JCO.Server implementation is started, does it act as a fully standalone component capable of receiving calls, or does it merely act as a sort of listener for some main SAP system? I'm not talking about a reliability on the two .dll files (or .so for Linux) that are required for the use of JCo, I just wish to know if the JCo package is entirely self-sufficient for server functionality or if it is intended to be linked to some SAP system.
A second problem I have is that the parameters passed to various constructors aren't clear to me... I'm not familiar with SAP terminology, nor have I worked with any client apps that make use of an SAP system.
The meaning of client strings, gwhost, gwservice, ashost, system IDs and program IDs mostly elude me, especially when it comes to knowing what client parameters must match what server parameters.
In order to familiarize myself with the classes, I've tried playing around with them a bit trying to create a small test app that first starts a JCO.Server instance, then tries to make a remote function call to it with a JCO.Client (within the same class, for simplicity and debugging purposes). I was wondering if this actually makes sense... Would a JCo client be capable of connecting to a JCo server, all running purely in Java, or is that nonsense?
To eliminate some common troubleshooting options, I'll quicly describe the steps I've taken:
Both librfc32.dll and sapjcorfc.dll were placed in the Windows system32 folder. Maybe only librfd32 needs to be placed there, but I copied both anyway to make sure.
The directory containing the jar file and both dll files is included in my environment path variable.
I've added a line to the C:\Windows\system32\drivers\etc\services file as follows:
sapgw00 3300/tcp #SAP System Gateway Port
I've opened port 3300 in my Windows firewall. In fact, I also tested with the firewall completely turned off.
However, I do not manage to get my test class to work. I've tried ports 3300, 3200 and 3600. I've tried various permutations of the client and server properties. I've tried removing the line from the services file, which would prompt the client to state upon connecting that the service "sapgw00" is unknown. When I add it back in, the error changes to "partner not reached", so it is definitely picking something up.
The server itself starts just fine, but connecting through a client doesn't work. My class source code is posted below. Maybe what I'm trying to do doesn't make any sense, but at the moment it's my best guess.
I realize this is a pretty long post and the class, while not exactly big, also implies a bit of reading of its own. But if anyone could give me any answers that are new to me, I'd be hugely grateful. Right now I'm kind of stuck, and just setting up the service and letting our customer test on it is a somewhat slow approach that can't match developing and testing on one and the same host.
Preliminary thanks to everyone who took the effort to read this.

If I understood you correctly, you want to provide a "service" that can be called from SAP. To provide this service you've chosen to implement an (external) RFC server program via JCo. One common method for RFC server programs is to register in SAP on the gateway - you do this by supplying the three parameters
<ol>
<li>jco.server.gwhost - SAP gateway host on which the server should be registered (so this would be the server name or IP address of the SAP gateway; localhost is only correct, if your RFC server program runs on the same server as the SAP gateway)</li>
<li>jco.server.gwserv - Gateway service, i.e. the port on which a registration can be done</li>
<li>jco.server.progid - Program ID under which your RFC server program can be reached (free, made-up case sensitive name, that should represent the service your RFC server is providing)</li>
</ol>
So essentially you're creating a listener, that is registered in SAP and waits for any invocations. Within SAP they will define a RFC destination, which basically represents a TCP/IP connection pointing to the SAP gateway where you registered with the given program ID. If you want more details, check the SAP help pages for <a target="_blank" href="http://help.sap.com/saphelp_nw04/helpdata/en/22/04262b488911d189490000e829fbbd/content.htm">RFC destinations</a> (you're looking for destination type T, see explanations <a target="_blank" href="http://help.sap.com/saphelp_nw04/helpdata/en/22/042652488911d189490000e829fbbd/content.htm">here</a>).
Usually gateway host and service (port) are given to you by the SAP basis folks and you tell them which program ID you're using. They will then enter those parameters in an RFC destination of type T in SAP. So no need for any of the client parameters you've mentioned. Although, I'd like to repeat, it's usually handy to also have SAP logon parameters maintained on your RFC server program, so that you can utilize the repository data from SAP (might be irrelevant in your case).
Hope this clarifies it a bit...

Calling JCO RFC Server program from JCO RFC client

Hi,
I have an RFC registered server program which implements JCO.Server. It seems to be working fine, when called from SAP.
For testing purposes, I was trying to write a JCO client program which would take the place of the SAP client.
This program opens a connection to the RFC server and executes a function e.g.
JCO.Client client = JCO.createClient("xx.yy.com", "sapgw35", "MYPROGID");
client.connect();
client.execute(function);
The RFC server program receives the call fine, when I test with a simple function which has no table parameters. However when I tried a more complex function with table parameters, I get an serverExceptionOccurred from the RFC server program:
com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: connection closed without message (CM_NO_DATA_RECEIVED)
    at com.sap.mw.jco.rfc.MiddlewareRFC$Server.nativeListen(Native Method)
    at com.sap.mw.jco.rfc.MiddlewareRFC$Server.listen(MiddlewareRFC.java:1368)
    at com.sap.mw.jco.JCO$Server.listen(JCO.java:6805)
I have tried to initialize the repositories in both server and client programs correctly, so that the function is in the cached function list and the table structures in the cached structures list before the function is invoked. But I am not sure if there is still something I am missing, so any ideas would be welcome.
Thanks,
Richard

JCO example 5 is a very good one for server side programming.
try the example,somethings you 'd better make clear.
1) JCO.server
2) repositories--data mapping
3) parameters: export import,table...
further topic:
1) JCO pool
2) tRFC,qRFC
After you have success in Client side programming,try example 5.

Issue in registering program id to SAP gateway using JCO

Hi All,
In our java application we are registering a program id to SAP gateway so that we can listen the data sent from R/3 systems.
I need some basic information about the gateway registeration. I have following queries :-
1. If I register a program id, till what time this registeration remains in the R/3 system.
2. Is there any way to do the permanent registeration.
3. In our scenario we have clustered java server which is set up on a clustered OS. That means one java server is on one hardware machine and other java server is on another machine. Once we register a program id from one of the java server ,it
gets registered with that particular machine IP address. Now if one of the java server gets down ,other java server should start listening to SAP system. But this is not happening because our other java server is on another machine whose IP address is different and is not registered with SAP system.Is there any way to deal with this situation. One thing we could think of is to register all the machines permanently with SAP system. So that whichever machine gets down communication will not break.All the machines will remain registered in the R/3. But I am not sure how to do that.
Can anyone help me here.
Thanks and Regards,
Reena

1.) The registration remains active until you unregister it, or until the SAP gateway recognizes that the connection has been interrupted somehow. If there are multiple registrations of the same programID, this is valid for each single one. So one could say, that a programID's registration is valid as long as at least one registration is still valid.
2.) There is no such thing. What do you mean with permanent registration?
3.) You already gave the answer by yourself. Just register all RFC servers from all nodes simultaneously. The RFC requests will be dispatched to any of the nodes all the time. If one server node gets down, the connections to this particular server will be interrupted and it won't receive any RFC requests any longer.
And you don't know how to do that? Just start the RFC servers on all server nodes and they will register at the SAP gateway. I don't understand this question.

Registering a program on the SAP gateway

Hi All
I have to setup an interface to an external application from SAP using ALE and IDocs. The external application needs to register an instance on the SAP gateway server. If this is complete then you only need to setup an RFC connection with a programID (The ID that is used in the gateway instance) and it will allow a connection between SAP and the external application.
The problem I am having is that I dont know how to register the external application on the SAP gateway. Can anyone help me with this problem?
Thank you.

No ehs management server is currently logged on at SAP Gateway

Hi,
I have installed EHS management server and WWI server on a separate server. The RFC between ECC Dev to WWI server is running fine. The ECC Dev server is able to call the registered program on SAPRFC.ini.
But when I run TCD CGSADM notthing is coming up and it throws error as "No ehs management server is currently logged on at the sap gateway".
I have checked and done whatever was required as per the sapnote 839750, 580586, but still CGSADM is not working.
Also in SMGW i can see the EHS server as Remote Gateway.
Kindly let me know how to rectify the Issue.
Thank You!

Hello

Same Program ID registered two times at SAP gateway

Hi Experts,
I Developed RFC to File scenario. In the sender rfc adapter i provided program id PID_SAP_ID. I used this program id in TCP/IP rfc destination.of r/3 system. I am running one report ZPM_SCHEDULE_OUTBOUND in r/3 to send data to XI. The problem is that, there are two instance of program id PID_SAP_ID registered in sap gateway because of this some times when I run the ZPM_SCHEDULE_OUTBOUND program, nothing is being passed to XI. What could possibly cause two instances of PID_SAP_ID program to run?
If anybody knows solution please let me know.
Thanks,
Venky

Hi Jakub Turminski ,
I am using that program id in one communication channel.

How to copy a Module Pool Program from one SAP server to another SAP server

Hi Experts,
My requirement is to copy some Module pool programs from one SAP server to another SAP server which do not have any link.
Please advise on this.
Regards
Dipak

put all relevant objects inside a transport request and release it. this will generate two files, a control file in /usr/sap/trans/cofiles/ and a data file in /usr/sap/trans/data/
you can take these two files, zip'em up and e.g. email them to your destination. There they have to be put into the same directories of that other server and can then be added to the import queue and finally imported.
These last steps would usually be done by an administrator.
Both systems should be on the same release, as far as I know.
Cheers
Thomas

Connect from SAP gateway to RFC server failed

Good day and a happy new year to you all!
I am failing to connect to my SAP BW system from BEx. The logon fails with this message:

I only experience this problem when connecting using any BEx component, but, I can successfully connect to the SAP BW system from SAP gui.
Additionally, I have the service 'sapdp02' defined in the services file, both on the workstation and the server.
What could be wrong or missing in my configuration?
Regards,
Joao.

hi Joao,
check if oss note 447882 relevant
you may ask basis for help
Symptom
You want to access the customer system using the BEx Analyzer.The connenction fails:The system displays the error RFC_ERROR_COMMUNICATION.In the detail screen, the system displays message "Partner not reached" (host 192.168.4.2, service sapgw 00).
Other terms
SAP Gateway, RFC_ERROR_COMMUNICATION, partner not reached
Reason and Prerequisites
The SAP gateway host is deactivated or the TCP/IP port 33xx (where xx corresponds to the system number) is not open.
Solution
Issue statement ping <IP address> (In this example:192.168.4.2) No reply: Boot SAP Gateway host required.
An answer:Check whether the TCP/IP port 33xx is open (where xx corresponds to the system number) and start the SAP gateway.
The TCP/IP port is also partially defined in the services file as an sapgw<SID> or sapgwxx entry (where xx corresponds to the system number). The services file is in the Windows directory or in WinNT/System32/drivers/etc.

Hi K Patil,
Acording to me you are faceing this issue because the entry of your backend System is not in the SLD (System Landscape Directory ) of your server.
to make this work you have to make entry in the SLD of your server

Unable to connect to SAP gateway to RFC server failed(hostname unknow)

Hi All,
I am trying to create a new Model(to connect to SAP R/3 server) using the following steps:
1.Selecting Import Adaptive RFC Model
2.Entering Model name,package,default logical system names
3.Selecting the single server option and giving the details of the SAP R/3 server.
When I try to connect it gives me the following error :
-Connect from SAP gateway to RFC server failed.
Also it mentions :
"ERROR hostname 'sapR3' unknown "
Where sapR3 is the entry corresponding to the IP address in the host file.
Further I am able to establish a telnet session using the same hostname in command prompt.
I have searched the Internet for solutions, but I haven't found any yet.Any ideas?
Regards,
Kshitij Agrawal

Hi,
Please check if the hostname that you specify in the "Reimport Model" GUI of NWDS matches with the application server name specified in your R/3 system.The same can be verified by following three simple steps:
1) Open the SAP LogOn.
2) Choose the server to which you wanted to connect and right click on it to get the "properties" in the context menu.
3) Look for the value entered in the field "Application Server" in the properties window.
Hope this helps.
