现在在做一个东西。上传PDF，然后实现一个功能，将PDF的内容取出来，再生成一个PDF。
现在已经将内容保存在oracle中，使用BLOB类型保存。已经保存好了。
我在debug下将取得的2进制的数据转为了string，打印出来类容是很乱的，各种乱码（如果是DOC的话，类容无乱码）
现在我应该怎么做才能将这些内容再次转为PDF并且保存下来呢？
下面是我的代码，
- Java code
OOByteInputStream ooois = new OOByteInputStream(img.getImageData());System.out.println("image data ----" + new String(img.getImageData()));//img.getImageData是能够取得保存在数据库中的值的com.sun.star.beans.PropertyValue xValues[] = new com.sun.star.beans.PropertyValue[2];xValues[0] = new PropertyValue();xValues[0].Name = "InputStream";xValues[0].Value = ooois;xValues[1] = new PropertyValue();xValues[1].Name = "Hidden";xValues[1].Value = new Boolean(true); // was boolean 'true' beforexComponentLoader = (XComponentLoader)UnoRuntime.queryInterface(XComponentLoader.class, xDesktop);xComponent = xComponentLoader.loadComponentFromURL("private:stream", "_blank", 0, xValues);com.sun.star.text.XTextDocument aTextDocument = (com.sun.star.text.XTextDocument) UnoRuntime.queryInterface( com.sun.star.text.XTextDocument.class, xComponent);OOByteInputStream.java

其中xComponent最后是Null。。搞半天也有没弄出来..其指导。起指点、、最后求包养~~~
