ErrorCodeIOException转换文件
我正在尝试实现Office基于LibreOffice 4.0的PDF转换系统并始终获取ErrorCodeIOException（尝试文件格式doc，docx，txt），我的stacktrace如下：

该行是在以下行中生成的：
xStorable.storeAsURL(sStoreUrl, propertyValues);
代码基于libreofice api的原始示例：

如果你能提供帮助，请提前感谢
换线
xStorable.storeAsURL(sStoreUrl, propertyValues);
至
xStorable.storeToURL(sStoreUrl, propertyValues);
