CREATING JCo RFC Provider Service. The RFC enables the execution of predefined functions in a remote or local system. This is done by registering the server Program to the ABAP gateway and the service is technically based on the JCo. Based on JCo 2 API, this service dispatches the incoming RFC requests to Java Beans. Introduction. When writing my first JCo server for I found it very cumbersome to find guiding code snippets and as well as a self-contains, fully working example. Hi Sebastian, Great Blog! I am not an abaper, it may be a basic question, appreciate your help on this. at the moment the standard SAP structure W3HTML length is 255 chars. how can we increase this length, becuase of this the JSON output is limited to 255 chars only not more than that. or JAVA screen as Frontend but for Backend they use ABAP code.

Configure RFC Destinations in ABAP & JAVA Environments Posted by ITsiti — December 21, 2011 in SAP BASIS — Leave a reply You need to create the following RFC destinations with both transaction SM59 ABAP and the Visual Administrator Java. In a Java-only system we have to use the Netweaver Administrator NWA or Visual Admin to unlock any user. But if all Admin users in a Java-only system are locked then we have to activate the emergency user SAP to unlock them. This can be done via Configtool. Once SAP is activated all other users will be deactivated untill SAP is disabled again.
In this course, participants will gain knowledge in configuring SAP Java Process Integration and learn how to implement different integration scenarios with SAP and non-SAP applications. The course comes with hands-on exercises. Also, the classic JCo framework is not integrated with SAP’s AS Java. For example, connections to ABAP systems cannot be configured in the NetWeaver Administrator. This is why the JCO RFC Provider was created. It is the JCo for the Java EE server environment, suited especially to the SAP AS Java. Using Java RFC packages In order to use Java BAPI Proxy Classes, the application programmer needs to be familar with some aspects of the Java RFC package: com.sap.rfc and com.sap.rfc.exception. The application programmer needs to provide IRfcConnection objects for logging on to R/3 so that the proxy objects can communicate with their corresponding instances.

Purpose. The purpose of this is to show you how to download, decompress, install NW RFC SDK, and set enverioment variable step by step. Overview. As of kernel 720 rfcexec.exe and startrfc.exe are no longer delivered together with kernel, however you want to use any of these programs. Calling RFC function module in SAP ABAP programs, call rfc function module with RFC destination A A- In the above example we have created a RFC destination and RFC function module, now we need call this function module in our program, see the example program for calling RFC.
