EOFException thrown when reading contents of ePub file

Question

I am trying to read the contents of an ePub file using the epublib library, and this example demonstrates this.

An exception occurs for me when loading a book from the input stream

// Load Book from inputStream Book book = (new EpubReader()).readEpub(epubInputStream); 

Not sure why the code doesn't work, and an exception is thrown for me? It worked for other StackOverflow users.

The Full Stack trace is used below:

Answer 1

An EOFException is thrown :

• if there is no data in the stream but you are trying to read. For example, read network stream methods, such as DataInputStream, ObjectInputStream throw EOFException , if they try to read from FileInputStream but FileInputStream is empty or

• if the formats do not match ... for example if an int is present and you are using readFloat () DataInputStream

Answer 2

You should try calling the method below before passing it to readEpub. Java Doc Link: http://docs.oracle.com/javase/7/docs/api/java/io/InputStream.html#available ()

 //assuming the above variables are already declared. if(epubInputStream.available() > 0) Book book = (new EpubReader()).readEpub(epubInputStream); else System.out.println("no data to read");
