Question

我正在按照以下示例从Java https://blogs.sap.com/2012/11/01/how-to-use-sap-gui-scripting-inside-java/进行文字描述。

Obj = new ActiveXComponent(Session.invoke("FindById",
      "wnd[0]/usr/txtRSYST-BNAME").toDispatch());
        Obj.setProperty("Text", "BCUSER");

      //-Set GUIPasswordField Password------------------------------
      //-
      //- session.findById("wnd[0]/usr/pwdRSYST-BCODE").text = _
      //-   "minisap"
      //-
      //------------------------------------------------------------
        Obj = new ActiveXComponent(Session.invoke("FindById",
          "wnd[0]/usr/pwdRSYST-BCODE").toDispatch());
        Obj.setProperty("Text", "minisap");

即使我传递了参数username和password，我仍然无法从Java启动SAP应用程序。我还需要修改什么才能使其正常工作？

Answer 1

要从头开始完成登录过程，您需要添加2个操作：

将saplogon.exe作为新进程启动
打开与所需SAP服务器的连接。对于此步骤，所需的连接需要已经在saplogon中进行了配置。
现在您可以运行代码来执行登录。

代码1。：

    //Opening the SAP Logon
    //this string should point to the saplogon.exe on your system.
    String sapLogonPath = "C:\\Program Files (x86)\\SAP\\FrontEnd\\SAPgui\\saplogon.exe";
    Process p;
    try {
        p = Runtime.getRuntime().exec(sapLogonPath);
        //the sleep is to let the system wait until the sap logon has fully loaded. You might reduce the time of the sleep depending on the performance of your system
        Thread.sleep(7000);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

2的代码：

        //SAP Connection Name
        //this string is the name of the connection configured in SAP Logon
        String sapConnectionName = "SAPServer"; 
        Connection = new ActiveXComponent(
        GUIApp.invoke("OpenConnection",sapConnectionName).toDispatch());

完整的独立工作示例代码：

下面是链接中的代码+所有必需的修改，以便启动SAP登录，打开连接并登录用户。
