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
