Java 中的 SAP GUI 脚本

Question

我正在按照下面的示例从 Java https://blogs.sap.com/2012/11/01/how-to-use-sap-gui-scripting-inside-java/ 处理 sapguiscripting。

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：

1. 将 saplogon.exe 作为新进程启动

2. 打开与所需 sap 服务器的连接。对于这一步，需要在 saplogon 中配置所需的连接。

3. 现在您可以运行代码来执行登录了。

1.的代码：

    //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());
