Question

java.util.HashMap cannot be cast to com.sap.conn.jco.JCoTable

private JCoTable table = (JCoTable) new HashMap();
我想new
一个JCoTable ，可是直接JCoTable table = new JCoTable（）是不行的，这个要怎么new呢

Answer 1

Properties logonProperties = new Properties();
logonProperties.put("jco.client.ashost", "10.10.11.22");
logonProperties.put("jco.client.client", "100");
logonProperties.put("jco.client.sysnr", "01");
logonProperties.put("jco.client.user", "username");
logonProperties.put("jco.client.passwd", "password");

File file = new File("sapconnection.jcoDestination");
FileOutputStream stream = new FileOutputStream(file, false);
logonProperties.store(stream, "SAP connection properties");
stream.close();
JCoDestination destination = JCoDestinationManager.getDestination("sapconnection");
JCoRepository repository = destination.getRepository();
JCoFunction function = repository.getFunction("Z_SD_XXXX");
JCoParameterList list = function.getImportParameterList();

//设置输入参数
list.setValue("PLANT", "1000");
...

function.execute(destination);
JCoTable rs = function.getTableParameterList().getTable("TABLE_HEAD");

//获取输出
List<HeadBean> sh = new ArrayList<HeadBean>();
for (int i = 0; i < rs.getNumRows(); i++) {
rs.setRow(i);
HeadBean s = new HeadBean();
s.setCompanyCode(rs.getString("COMPANY_CODE"));
s.setSalesOrg(rs.getString("SALES_ORG"));
...
sh.add(s);
}

我要的只是new一个JCoTable table，连接SAP接口啊

Answer 2

用JCO.createTable，构造函数是不可见的。

追问

JCo.createTable(null)；刚刚试了，null是不可以的，要new 一个JCoRecordMetaData这个接口的实现类，可是不知道实现类是什么
