如何使用Java和OpenOffice UNO API操作odt文件中的嵌入式文件

我找到了一种在ODF文件中存储自定义文件的方法，将它们存储在一个新的资源目录中，并将其包含在一个新的mimetype下的清单中

我想知道的是如何在Java OpenOffice附加组件中实现以下功能：

读取“我的资源”中的文件：是否可以获取其内容的InputStreamReader

创建一个新文件：我能以某种方式创建并写入一个新文件吗

关于如何做到这一点的任何想法。我不熟悉UNOAPI，有点困惑

/* this java code need one jar file named with odfdom-java 0.8.6 , and it will able to read any odt file and can store in string and can also change the content of the original file on new or existing file what ever your requirement . if you want to create new file then give new file name and path at the method "document.save("D:/newFile.odt")".
