我正在尝试使用 JCo 连接到 SAP ECC 6.0。我正在关注本教程。但是,有一个注释说:
For this example the destination configuration is stored in a file that is called by the program. In practice you should avoid this for security reasons.
这是合理且可以理解的。但是,没有说明如何设置安全目的地提供者。我在这个线程中找到了创建自定义实现DestinationDataProvider
并在我的本地机器上工作的解决方案。但是当我在 Portal 上部署它时,我收到一条错误消息,指出已经注册了DestinationDataProvider
. 所以我的问题是:
如何在 SAP Java EE 应用程序中存储目标数据?
这是我的代码,以进一步阐明我要做什么。
public static void main(String... args) throws JCoException {
CustomDestinationProviderMap provider = new CustomDestinationProviderMap();
com.sap.conn.jco.ext.Environment.registerDestinationDataProvider(provider);
Properties connectProperties = new Properties();
connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, "host.sap.my.domain.com");
connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR, "00");
connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, "100");
connectProperties.setProperty(DestinationDataProvider.JCO_USER, "user");
connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, "password");
connectProperties.setProperty(DestinationDataProvider.JCO_LANG, "en");
provider.addDestination(DESTINATION_NAME1, connectProperties);
connect();
}
public static void connect() throws JCoException {
String FUNCTION_NAME = "BAPI_EMPLOYEE_GETDATA";
JCoDestination destination = JCoDestinationManager.getDestination(DESTINATION_NAME1);
JCoContext.begin(destination);
JCoFunction function = destination.getRepository().getFunction(FUNCTION_NAME);
if (function == null) {
throw new RuntimeException(FUNCTION_NAME + " not found in SAP.");
}
//function.getImportParameterList().setValue("EMPLOYEE_ID", "48");
function.getImportParameterList().setValue("FSTNAME_M", "ANAKIN");
function.getImportParameterList().setValue("LASTNAME_M", "SKYWALKER");
try {
function.execute(destination);
} catch (AbapException e) {
System.out.println(e.toString());
return;
}
JCoTable table = function.getTableParameterList().getTable("PERSONAL_DATA");
for (int i = 0; i < table.getNumRows(); i++) {
table.setRow(i);
System.out.println(table.getString("PERNO") + '\t' + table.getString("FIRSTNAME") + '\t' + table.getString("LAST_NAME")
+'\t' + table.getString("BIRTHDATE")+'\t' + table.getString("GENDER"));
}
JCoContext.end(destination);
}
