1.把librfc32.dll,sapjcorfc.dll 放到服务器的系统的c:\windows\system32目錄下

(不然会报错：sap Field IT_TABLnot a member of TABLES)

2.下载 sap.jar;sapjco.jar;sappool.jar加到JAVA应用下. 3.下面类代码可以查物料数据 import com.sap.mw.jco.*; import com.sap.mw.jco.JCO.Function; class SAPServer extends JCO.Server { public SAPServer(JCO.Repository repo) { super ("10.10.10.50", "sapgw00", "ABC", repo); } } class SAPLogon { public JCO.Client mConnection; public JCO.Repository mRepository; public SAPLogon(String client, String userid, String password, String language, String ip, String system_number) { try { mConnection = JCO.createClient(client, userid, password, language, ip, system_number); mConnection.connect(); mRepository = new JCO.Repository("Lee", mConnection); System.out.println("SAP连接成功"); //调用RFC函数 IFunctionTemplate ft = mRepository.getFunctionTemplate("BAPI_MATERIAL_GET_DETAIL"); JCO.Function f = ft.getFunction(); //1.传入参数为Field f.getImportParameterList().setValue("931029BA", "MATERIAL"); f.getImportParameterList().setValue("1000", "PLANT"); mConnection.execute(f); //1.返回参数为Field JCO.Structure struct = f.getExportParameterList().getStructure("MATERIAL_GENERAL_DATA"); String name = struct.getString("MATL_DESC"); System.out.println("物料名:"+name); String MATL_TYPE = struct.getString("MATL_TYPE"); System.out.println("物料类型:"+MATL_TYPE); mRepository = new JCO.Repository("my_repository", mConnection); mConnection.disconnect(); } catch (Exception ex) { ex.printStackTrace(); System.exit(1); } } } public class Main { public static void main(String[] args) { SAPLogon mySAP = new SAPLogon("800", "userid", "passwork", "zh", "21.4.13.2", "00"); SAPServer myServer = new SAPServer(mySAP.mRepository); myServer.start(); } }
