java代码启动cmd执行命令来开启服务出现无法连接的问题

Question

我想使用openoffice的格式转换功能，需要先开启openoffice的服务，当我手动敲入命令的时候，是可以运行起来的，但是通过Java代码执行却出现拒绝连接的问题，请帮我看看怎么回事

public static String soffice_host = "127.0.0.1";
public static String soffice_port = "8100";
public static Process pro = null;
String commands = "cmd.exe /C C:\\Program Files (x86)\\OpenOffice 4\\program\\startOpenoffice.bat";
System.out.println(commands);
//执行的命令：cmd.exe /C C:\Program Files (x86)\OpenOffice 4\program\startOpenoffice.bat
pro = Runtime.getRuntime().exec(commands);
connection = new SocketOpenOfficeConnection(soffice_host, Integer.parseInt(soffice_port));
System.out.println("获得连接"+connection);
//获得连接com.artofsolving.jodconverter.openoffice.connection.SocketOpenOfficeConnection@7002ee59
connection.connect();

startOpenoffice.bat:

soffice -headless  -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard 

错误信息：

手动敲命令：

cd C:\Program Files (x86)\OpenOffice 4\program
soffice -headless  -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

Answer 1

通过查找资料发现一个新的包jodconverter-core，其中有个OfficeManager类可以实现另外的连接方式，我的问题是启动一次后，就可以连接，所以刚好可以，只能暂时这样解决了。

Answer 2

换种方法执行cmd：

 ProcessBuilder builder = new ProcessBuilder(
            "cmd.exe", "/c", "C:\\Program Files (x86)\\OpenOffice 4\\program\\startOpenoffice.bat");
        builder.redirectErrorStream(true);
        Process p = builder.start();
        BufferedReader r = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String line;
        while (true) {
            line = r.readLine();
            if (line == null) { break; }
            System.out.println(line);
        }

===========================================
String OpenOffice_HOME = "C:\Program Files (x86)\OpenOffice 4";// 这里是OpenOffice的安装目录,    

            if (OpenOffice_HOME.charAt(OpenOffice_HOME.length() - 1) != '\\') {
            OpenOffice_HOME += "\\";
            }
            Process pro = null;
            try {
                String command = OpenOffice_HOME  
                        + "program\\soffice.exe -headless -accept=\"socket,host=127.0.0.1,port=8100;urp;\"";
                pro = Runtime.getRuntime().exec(command);    //启动openoffice服务
                OpenOfficeConnection connection = new SocketOpenOfficeConnection("127.0.0.1", 8100);
                connection.connect();
                DocumentConverter converter = new OpenOfficeDocumentConverter(connection); 
                converter.convert(SourceFile, HtmlFile);
                HtmlFile.createNewFile();
                connection.disconnect();  
            } catch (java.net.ConnectException e) {
                System.out.println(e.getMessage());
                System.out.println("OpenOffice服务未启动");
            } catch (com.artofsolving.jodconverter.openoffice.connection.OpenOfficeException e) {
                e.printStackTrace();
                System.out.println("读取文件失败");
            } catch (Exception e){
                e.printStackTrace();
               System.out.println("其他异常");
            }finally{
                pro.destroy();  //销毁openoffice服务
            }
