问题 I would like to execute RFC function on explicit destination using JCo. I've modified existing JCo StepByStepClient.java and I'm able to execute RFC function exactly the same way like using Sap GUI "se37" when the "RFC target sys" field is empty . For my demo purposes I was invoking "TH_USER_LIST" function. Then I registered my own JCo server with Program Id "MY_PROG_ID", then added tcpip destination "MY_DEST" using "sm59" with "Registered Server Program"="MY_PROG_ID". I'm now able to invoke

问题 Earlier this year I developed an implementation of the SAP JCO CustomDestinationProvider for one of my Spring MVC tomcat applications. In my application, I use this implementation to call a BAPI in my SAP R/3 system to retrieve data. I am now working on a second Spring MVC tomcat application that I want to have call a BAPI in my SAP R/3 system to retrieve data. It will be a different BAPI that I will be calling, thus it will be different data that I will be retrieving. Since this is a

问题 I'm developing a IDOC server which can connect to multiple destinations on same SAP system(gateway host will be same) and receive IDocs. I'm not sure that I need multiple JCoServer instance running or single JCoServer with multiple destinations. If latter is the case, why would there is a parameter to specify the destination name using jco.server.repository_destination property when providing the server data? 回答1: The property jco.server.repository_destination is for telling the JCoServer

问题 I am a new comer to both SAP and JCo. I established connection to a SAP Server and I would like to print a list of BAPIs in my program . is there any way to do it?? I am using sapjco3.jar 回答1: As far as I know, there is no "BAPI to get a list of BAPIs", so this would be a non-trivial task. You could try to use RFC_FUNCTION_SEARCH to search for function modules named BAPI* , but that's not guaranteed to give you a) only official BAPIs and b) all of the official BAPIs... 回答2: You can also use

问题 In my java web application, trying to connect SAP Server. This error is generated. I have placed the sapjco3.dll and sapjco3.jar in WEB-INF/lib/ and also configured in the Java Build Path. I have also set the Path in servlet as System.setProperty("java.library.path", "/WEB-INF/lib"); But also error existing. 回答1: There are several issues in your approach It is not recommended to change java.library.path programmatically, since the property is cached at the JVM start. See Setting "java.library

问题 I am trying to create a Purchase Info Record (ME11) in SAP using the below JCo code: It executes without fail and throws no error, but i am not able to get the newly created info record in SAP. In ME13 it says info record not found. Can i know what am i missing?

问题 I need to connect to SAP Systems via standard BAPI calls. I already installed JCo (sapjco3) and added the .jar to my build path in Eclipse. But due to the fact that I am rather a beginner regarding network/server programming, I have no idea how to setup a connection between Eclipse and the SAP Systems...can anyone provide a basic solution or some ideas for that? Thank you and greetings! 回答1: I solved the question by myself after having found a good documentation with examples regarding that

问题 I'm Having a problem establishing a connection to SAP in my java program.

问题 I got another JCo-related question and hopefully finding help. With JCo you can easily build up a connection like it is explained in the example sheets which came with the JCo-library. Unfortunately, the only way building a connection is handled with a created property file. It wouldn´t be that bad, if there wasn´t any sensible data in it. But at least, the password for the SAP user stands in the file, so it is a lack of safety in this way of connection-handling. The manual of JCo says so,
