Think of integrating with an SAP system. You can have your IDoc and RFC interfaces imported directly into XI, but is it that simple in case of any third party ERP? The diagram below shows the process of importing RFC interfaces in XI.
For comparison, let's look at the case of JD Edwards:
As we have RFCs and BAPI in SAP, we have business functions in JDE. The business functions in case of JDE are written in a JDE-specific language. There is a tool called as GenJava provided by JD Edwards itself, which we can use to create a JAR file of the business function. The output for GenJava produces fully functional Java objects based on the library you use to generate wrappers. GenJava packages these objects in a single JAR file such as XXXInterop.jar or XXXXInteropDoc.jar, where XXXX is the name of function which we provide from the command line. For example the command can be as follows: GenJava /Cat 1 /UserID Devuser1 /Password Devuser1 /Environment DV811 CAEC. Along with the adapter IWAY, it also provides a servlet application called as application explorer which creates XML schema definitions (XSD) for the generated Java objects. Using the servlet "application explorer", we can create request and response schemas (XSD) for that particular Java function. Thus, we get the XSD files for request and response which we can import in external definitions in the integration repository. For one thing, that shows the advantage of being on open standards. Steps for configuring and using the JDE adapter are as follows:
1. JD Edwards adapter software installation.
