求助：使用oppenoffice转换文件格式时报错Cannot run program "C:\Program": CreateProcess error=2, 系统找不到指定的文件

在做预览功能的时候使用转换文件格式的工具类，之前还好好的，可以使用。今天访问就报错了，工具类代码如下：
public static int office2PDF(String sourceFile, String destFile) {
try {
File inputFile = new File(sourceFile);
if (!inputFile.exists()) {
//inputFile.mkdir();
return -1;// 找不到源文件, 则返回-1
}

        // 如果目标路径不存在, 则新建该路径  
        File outputFile = new File(destFile);  
        if (!outputFile.getParentFile().exists()) {  
           outputFile.getParentFile().mkdirs();
        }  

        String OpenOffice_HOME = "C:\\Program Files (x86)\\OpenOffice 4\\program";//这里是OpenOffice的安装目录, 在我的项目中,为了便于拓展接口,没有直接写成这个样子,但是这样是绝对没问题的  
        // 如果从文件中读取的URL地址最后一个字符不是 '\'，则添加'\'  
        if (OpenOffice_HOME.charAt(OpenOffice_HOME.length() - 1) != '\\') {  
            OpenOffice_HOME += "\\";  
        }  
        // 启动OpenOffice的服务  
        String command = OpenOffice_HOME  
                + "program\\soffice.exe\",\"-headless -accept=\"socket,host=127.0.0.1,port=8100;urp;\" -nofirststartwizard";  
        Process pro = Runtime.getRuntime().exec(command);  
        // connect to an OpenOffice.org instance running on port 8100  
        OpenOfficeConnection connection = new SocketOpenOfficeConnection(  
                "127.0.0.1", 8100);  
        connection.connect();  

        // convert  
        DocumentConverter converter = new OpenOfficeDocumentConverter(  
                connection);  
        converter.convert(inputFile, outputFile);  

        // close the connection  
        connection.disconnect();  
        // 关闭OpenOffice服务的进程  
        pro.destroy();  

        return 0;  
    } catch (FileNotFoundException e) {  
        e.printStackTrace();  
        return -1;  
    } catch (ConnectException e) {  
        e.printStackTrace();  
    } catch (IOException e) {  
        e.printStackTrace();  
    }  
    
    return 1;  
}
控制器中代码如下：
@RequestMapping(value = "converttopdf.action")
	public String coursePageWaiting(HttpServletRequest request,Model model) {
		String sourceFile="C:\\Program Files (x86)\\onlinelook\\Bbbbb.doc";
		String destFile=request.getSession().getServletContext().getRealPath("/upload")+File.separator+"Aaaaa.pdf";
		converttopdf c=new converttopdf();
		if(c.office2PDF(sourceFile, destFile)==0) {

// String path = request.getSession().getServletContext().getRealPath("/upload");
// File f=new File(destFile);
// File up=new File(path+"/"+f);
// boolean mkdir = up.mkdir();
// System.out.println(mkdir);
// System.out.println(path);
// System.out.println(f);
// System.out.println("====================");
System.out.println(destFile);
File f=new File(destFile);
model.addAttribute(“filename”,f.getName());
return “/look”;
}else if(c.office2PDF(sourceFile, destFile)-1){
return “没找着”;
}else if(c.office2PDF(sourceFile, destFile)==1) {
return “失败”;
}else {
return “哈哈哈”;
}
}
报错信息如下：
