Call RFC using java procedure

Hi
How can I to use java procedure and call RFC for to access tables of SAP ?
Thank You

RFC? That term in the IT environment usually means "+Request For Comments+" and refers to Internet protocol and usage standards.
Do you perhaps means RPC (Remote Process/Procedure Calls)? Or something else?
Also, SAP is a company. Not a product. SAP has a product called R3. This runs inside a database.
Connecting from Java to a database typically requires nothing more than a JDBC driver. So why can't you use a JDBC driver and need to call the database (and access tables) using another method?

Problem when call rfc using function control

i try to call rfc using functin control but error "wdtfuncs error '800a03eb' Fail to call Remote Function Module" be popuped.
my code like that:
Set objSAPFunction = Server.CreateObject("SAP.Functions")
          Set objSAPFunction.Connection = objSAPConn.NewConnection
          IsLogOnSAP = False
          If objSAPFunction.Connection.Logon(1, True) Then

          End If
These code can run on the A machine, but do not run on the B machine. And both two machines have been installed SAP FrontEnd.
which problem about it?

To change all definition of parameters of the function from type to like may be solution.

Without BPM:Call RFC using JCO in interface mapping using java mapping

Hi all
I have a very small scenario where REQUEST from the customer comes via Web Service all i have to do is to read the request using SOAP adapter and call an interface mapping(lets say the name is IM_TEST) inside which there is a JAVA MAPPING program written which will call an RFC in CRM using JCO.
Now this was really simple and i cud test the Interface mapping successfully, but the problem is when loading the scenario in integration directory i have certain things to do
1. to set the SENDER AGREEMENT which i did correctly
2. set the RECEIVER DETERMINATION, INTERFACE DETERMINATION AND RECEIVER AGREEMENT now here i am stuck because there is no receiver in my case as the RFC is called inside the mapping only.
can i call one more message mapping in IM_TEST which will write file onto the XI directory and then in RECEIVER DETERMINATION, INTERFACE DETERMINATION AND RECEIVER AGREEMENT i can mention the reciever as FTP.
I tried it but i gives the following error
Runtime exception occurred during execution of application mapping program com/sap/xi/tf/_MM_TEST_WRITE_FILE: com.sap.aii.utilxi.misc.api.BaseRuntimeException; Parsing an empty source. Root element expected!
Please help me how to complete the scenario so that customer can run it end to end.

Stefen
What do i do then...actually this is the project requirement. They want a very fast response from PI and thats why they wnt us to omit BPM and the Graphical mapping from the scenario.
I am able to test the interface mapping which calls the the Java mapping inside which there is an RFC call, but i cannot implement it end - to - end as there is no receiver business system in this case. The only business system i have is the SOAP sender.
I am really troubled now, please help me with a solution.
Is there any other possible way through which the process can become very fast whic hcan meet their requirement.

Call RFC from java (j2ee) / call to j2ee from R/3

hello
i´ve browsed the forum for some time to find how to:
1.) call ejb from r/3 system via rfc
2.) call rfc enabled function modules on r/3 from within an j2ee enviroment
but i didn´t quite get it, because i was a bit confused about all the mentionend techniques
what i found out about
1.) use ejb (session bean) and jndi; configure RFC-Engine Service (we use sap webas)
2.) use jco / jca
(or all rfc enables rfm´s are available as web service, but didn´t find anything about this)
so my question:
are these the preferred techniques to connect j2ee (webAS) <-> r/3; if not are there any others, maybe easier methods?
and last but not least: are there any good online tutorials for this topic?
thanks in advance
franz

Just as a short partial reply.
The generic Java --> RFC method is JCO (it will work on older versions as well), you can think of it as a JDBC driver where R/3 is the database, it behaves very similar in many ways.
EJB development on SAP WAS is really not any different from EJB development on any other J2EE server. The deploy tool is superb. very easy to use and the JNDI registry, etc. are standard stuff...
ABAP to EJB calls, haven't looked at this in over a year now, but back then we did a Proof Of Concept based on information at http://help.sap.com and it did work indeed. The only thing was back then that you needed to do a few tweaks to get it to work properly.
As mentioned above, look at the JCO examples and then you can ask more specific questions once you get stuck.
Good Luck!

Kalle

venujTry this simple webservice client.
You will need apache-axis.jar in your classpath. The following client is apache axis based. A similiar client can be built also using the JAX-WS only[without apache-axis.jar].
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
public class WEBSERVICE_CLIENT{
public static void main(String [] args) {
try {
String endpoint ="<YOUR WS ENDPOINT>";
        Service service = new Service();
        Call     call    = (Call) service.createCall();
        // YOU CAN SET VARIOUS PROPERTIES IN THE "CALL" OBJECT...LIKE
        // USERNAME,PASSWORD,PROPERTIES OF HTTP HEADER. SEE "CALL" OBJECT'S API FOR MORE PROPERTIES.
        call.setTargetEndpointAddress( new java.net.URL(endpoint) );
        call.setOperationName(new QName("<YOUR WS SERVICE NAMESPACE>", "<WS SERVICE TO BE INVOKED>"));
        String msg = (String) call.invoke( new Object[] { "data" } );
        System.out.println("RETURNED MESSAGE : "+msg);

Calling RFCs in Java WebDynpro

Hello Experts,
I'm new to WebDynpro. I'm a novice at best and have just learned the basics. I'll probably be asking a lot of questions about this soon. Here is one problem I recently encountered:
I managed to call RFCs from R/3 using a user input and then another one by using one field retrieved from the first called RFC. Now i have to call a BAPI recursively from the data I got from the 2nd RFC that I called.
Here is the code so far:
public void executeBapi_Network_Getdetail_Input( )
    //@@begin executeBapi_Network_Getdetail_Input()
    //$$begin Service Controller(246259973)
    IWDMessageManager manager = wdComponentAPI.getMessageManager();
    try
      BigDecimal plannedCost = new BigDecimal(0);
       for (int i=0; i<wdContext.nodeZps_Fm_Get_Network_Num_Input().nodeNetworks().nodeEx_Networks().size(); i++) {
          wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Network(false);
          wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Network_Activity(true);
          wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Relation(true);
          wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Activity_Element(true);
          wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Activity_Milestone(true);
          wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Component(true);
          wdContext.currentBapi_Network_Getdetail_InputElement().setNumber(
            wdContext.nodeZps_Fm_Get_Network_Num_Input().nodeNetworks().nodeEx_Networks().getEx_NetworksElementAt(i).getAufnr());
          wdContext.currentBapi_Network_Getdetail_InputElement().modelObject().execute();
          wdContext.nodeNetworkDetails().invalidate();
          plannedCost.add(wdContext.nodeBapi_Network_Getdetail_Input().nodeNetworkDetails().nodeE_Network().getE_NetworkElementAt(i).getPlanned_Cost());
sorry if this is totally wrong. I'm totally a newbie here.
Hoping for your kind and helpful responses.
Cheers,
Alfonso

Hi Alfonso,
Can you please try this code:
       IWDMessageManager manager = wdComponentAPI.getMessageManager();
         try
           BigDecimal plannedCost = new BigDecimal(0);
           // Initializing a IWDNode to make code more readable and clean
           IWDNode nodeEx_Networks = wdContext.nodeZps_Fm_Get_Network_Num_Input().nodeNetworks().nodeEx_Networks();
           // I have initialized the int variable because you should never calculate the size() in for loop.
           // It is major performance hit.
           int size = nodeEx_Networks.size();
           for (int i=0; i<size; i++) {
               wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Network(false);
               wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Network_Activity(true);
               wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Relation(true);
               wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Activity_Element(true);
               wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Activity_Milestone(true);
               wdContext.currentBapi_Network_Getdetail_InputElement().setI_Without_Component(true);
               wdContext.currentBapi_Network_Getdetail_InputElement().setNumber(nodeEx_Networks.getEx_NetworksElementAt(i).getAufnr());
               wdContext.currentBapi_Network_Getdetail_InputElement().modelObject().execute();
               // WHY IS THIS INVALIDATE DONE.. WHICH IS THIS NODE???
               wdContext.nodeNetworkDetails().invalidate();
            IWDNode nodeE_Network = wdContext.nodeBapi_Network_Getdetail_Input().nodeNetworkDetails().nodeE_Network();
              int sizeNetwork_Getdetail = nodeE_Network.size();
              for (int i = 0; i < sizeNetwork_Getdetail; i++) {
                   plannedCost.add(nodeE_Network.getE_NetworkElementAt(i).getPlanned_Cost());
              // Now you can check the plannedCost by printing it using the manager you have initialized above.
I hope this solves your issue. If you have any further issue please revert back.
Thanks and Regards

How to calculate call duration using java card API

Hi,
I am developing an application using Java card API. I want to calculate duration of otgoing calls in it. I am trying to start timer at the beginning of call in Call Control event. Can someone kindly check following code of Call control event? Here timerManagement function is sending proactive command for starting timer for 3 hours. Here I am asuming that maximum call will be of 3 hours. In callDisconnect event i can get current value of timer and use it to calculate duration of call. But this scenario is also not working.
Problem is that during code execution program stuck at send command (proHdlr.send();) of timmerManagement function. I am sending postAsBERTLV command before starting timer so may be reason is that it is not possible to send proactive command while phone is busy.
But I also cannot send postAsBERTLV after timerManagement function. Because it is mention in specification that "The EnvelopeResponseHandler content must be posted before the first invocation of a ProactiveHandler.send method or before the termination of the processToolkit, so that the GSM applet can offer these data to the ME (eg 9Fxx/9Exx/91xx). After the first invocation of the ProactiveHandler.send method the EnvelopeResponseHandler is no more available"
Take a look at following code
                 * Method illustrating the use of the Call Control event.
                private void callControlService() {
                                /** @todo: Replace following sample code with your implementation */
                                ProactiveHandler proHdlr = ProactiveHandler.getTheHandler();
                                EnvelopeHandler envHdlr = EnvelopeHandler.getTheHandler();
                                ProactiveResponseHandler rspHdlr = ProactiveResponseHandler
                                                                .getTheHandler();
                                EnvelopeResponseHandler envRspHdlr = EnvelopeResponseHandler
                                                                .getTheHandler();
                                durationCount = 0;
                                 // allow call with no modifications
                                envRspHdlr.postAsBERTLV((byte)0x9F, (byte)0x00);
                                // start clock using timer
                                timerManagement(proHdlr, rspHdlr, (byte) 0x0, timer_id, tempBuffer);
                                return;
                }Please help me in this regard
Thanks
Yasir

I am also unable to start timer in call connected event. I cannot send any proactive command while phone is busy. I am using Gemalto development Suite and there simulators (Simulation 2G chain).
Is it limitation of simulator that you cannot send any proactive command while phone is busy?
Is there any other work around for getting call duration?

How to create database connection and how to call it using Java

Hi,
Good day! I'd like to know how I can create a db connection in JDev, then use this connection to retrieve data using a Java Class? I've seen using New Gallery > Database Connection. But I'm not sure how I can access this connection using Java and display some output from the retrieved records.
Any steps/tutorial link is appreciated.
Thanks in advance,

Hi,
If you need to access the connection in the entity object then refer http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/bcadvgen.htm#BABEIFAI i.e in MODEL.
But if you want to access connection in ViewController part of application then you need to do it manually.For this i am giving you my code for reference.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Problem while calling RFC in java

hi,
I writed a java program calling a batch input RFC. The RFC return an internal table which storing the system messages of the batch input process. My problem is:

hi,
i had resolved my problem in other way.I don't upload my data using ws_upload now,but upload with table.
here is my code.Maybe helpful to somebody:
       JCO.Table C_XYORDERTable;
     JCO.Table C_XYORDPR_FINALTable;
     public void getXyordprFinalElement(Element e) {
          try {
               for (Iterator i = e.getChildren().iterator(); i.hasNext();) {
                    Element child = (Element) i.next();
                    if (child.getName().equals("ORDER_ID"))
                         C_XYORDPR_FINALTable.setValue(child.getText(), "ORDER_ID");
                    else if (child.getName().equals("ID"))
                         C_XYORDPR_FINALTable.setValue(child.getText(), "ID");
                    else if (child.getName().equals("PRODUCT_ID"))
                         C_XYORDPR_FINALTable.setValue(
                              child.getText(),
                              "PRODUCT_ID");
                    else if (child.getName().equals("MATNR"))

Call rfc from Java Web application.

Hi:
I am new to SAP Java programming.
I am developing a java web application on SAP NW SP16.
I need to call a rfc and process the data to be displayed on a jsp page.
I have few questions...
1) Can I use the JCO destination created in thru wed dynpro content administrator, to connect to sap and execute the rfc/bapi?
2) How would I create and access the model (rfc)?
3) Are the required jar and dll(rfc32.dll ... ) files available on the server?
Any help would be greatly appreciated.
Thanks.

Hi,
See the follwoing links which contains sample code to ceate JCO and execute BAPI.

Pointbase database using java procedure in trigger

Hi,
I use Sun Creator to create my Single.war archive.
�\src\db contains package db;
In it is public class braincreate;
Inside of braincreate is public void triggerInsert1 (aa,bb);
�\src\single contains package single;
In it is public class Page1;
Inside of Page1 is code to create and execute Pointbase Trigger. The Trigger calls stored procedure triggerInsertxx, which in turn executes CALL which has \"db.braincreate::triggerInsert1\" declaration.
All other issues, including connection, settings and so on are resolved. When ran in debug mode the following error is raised:
"The external \"db.braincreate::triggerInsert1\" routine had the following runtime exception \"java.lang.ClassNotFoundException: db.braincreate\""
I also tried to put the method to class Page1, but it still did not work. I tried to change CLASSPATH to point to compiled Single.war, but it still did not work.
Question:
How to set the code so triggerInsert1 is found and executed? Maybe I need to put .war file or package in some specific place?
I tried to rename Single.war to Single.jar and put it in ...\Creator2ea\...java\lib\ext (does anybody know if it makes sense?), but it did not work.

Please find further discussion in:
http://swforum.sun.com/jive/thread.jspa?forumID=123&threadID=63068

Calling RFC using UDF

Hi,
I have a small doubt.
In file to IDOC mapping, I am mapping two fields using a UDF.
That UDF in turn calls a RFC.
But that RFC is not moved to quality server.
If now I try to test that in quality environment, the mapping works fine and IDOC is posted because the error handling is done in ABAP.
My doubt is why did the messge did not failed in XI, saying the RFC not available??
I tried to search in sdn, by did not get anything related to this.
Please try to clarify my doubt.
Regards,
Sachi
