Make a JavaFX application calling a BAPI, using your SAP NetWeaver 7.1 Composition Environment

[Former Member]

Try this five minutes tutorial and run your first JavaFX application calling a BAPI

Prerequisites:
1. Install JavaFX Eclipse plugin in your Developer Studio 7.1 .
https://openjfx.dev.java.net/javafx-eclipse-plugin-install.html

2. Make the JavaFX HelloWorld tutorial
http://www.mrbool.com/articles/viewcomp.asp?comp=5549

JavaFX BAPI Call Tutorial:
1. Reference JCO library
Click right button over helloworld proyect at Package Explorer, Properties, Java Build Path, Libraries, Add External JARs, search sapjco.jar in your Developer Studio plugins folder ( something like "C:\Program Files\SAP\IDE\IDE71\eclipse\plugins\com.sap.mw.jco\lib" )

2. Create a Java class with Backend Call
Click Right button over helloworld proyect at Package Explorer, New, Class, name: BAPICall, put this class code and change attributes to connect to your SAP system:

import java.io.StringWriter; import com.sap.mw.jco.JCO;  public class BAPICall {            public static String getResult(String airline)  {                      String result = "";                      try {              JCO.Client mConnection;              JCO.Repository mRepository;              JCO.Function mFunction;                           JCO.Table mTable;               mConnection =                   JCO.createClient("100", // SAP client                                            "USER", // userid                                            "PASSWORD", // password                                            "EN", // language                                            "myhost", // application server host name                                            "00"); // system number                            mConnection.connect();                           mRepository = new JCO.Repository("SDNSample", mConnection);              mFunction = mRepository.getFunctionTemplate("BAPI_FLIGHT_GETLIST").getFunction();              mFunction.getImportParameterList().setValue(airline, "AIRLINE");              mConnection.execute(mFunction);              mTable = mFunction.getTableParameterList().getTable("FLIGHT_LIST");              StringWriter writer = new StringWriter();              mTable.writeHTML(writer);              result = writer.getBuffer().toString();                                        mConnection.disconnect();                      }         catch (Exception ex) {              result = ex.getMessage();         }                 return result;      }            }

3. Create JavaFX main file
Create BAPICall.fx JavaFX file ( like in new JavaFX file creation in Helloworld tutorial ), put this code:

import javafx.ui.*;  class ModelAttributes {     attribute strTable: String;     attribute strFilter: String; }  var model = new ModelAttributes();          Frame {             title: "JavaFX application calling a BAPI"              content:             SplitPane {                     orientation: VERTICAL                     content:[                     SplitView {                          content:                          FlowPanel {                               alignment: LEADING                               content:[                              SimpleLabel {                                                                text: "Airline:"                                                                },                              TextField {                                   columns: 50                                   value: bind model.strFilter                              },                              Button {                                   text: "Search"                                   action: operation() {                                              model.strTable = BAPICall.getResult("{model.strFilter}");                                   }                              }]                     }                 },                 SplitView {                     content: Label {                         opaque: true                         preferredSize: {height: 250 width: 250}                                              text: bind "{model.strTable}"                     }                 }]             }              visible: true         }

4. Set JavaFX class to run.
In main menu: Run, Run..., JavaFX application, HelloWorld JavaFX, Arguments, Program arguments, change "HelloWorld" to "BAPICall", Apply and RUN!!!

5. Runtime:
You are going to call to BAPI_FLIGHT_GETLIST with an AirlineID filter.
