JAVA通过JCO连接SAP例子

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();
}
}
