Java API to Convert EPUB to OTT

  1. Open EPUB file using Document class
  2. Convert EPUB to DOC by using save method
  3. Load DOC file by using Document class of Aspose.Words
  4. Save the document to OTT format using save method and set OTT as SaveFormat

Get Started with Java File Manipulation APIs

You can easily use Aspose.Total for Java directly from a Maven based project and include Aspose.PDF for Java and Aspose.Words for Java in your pom.xml.

Alternatively, you can get a ZIP file from downloads .

// load EPUB file with an instance of Document class
Document document = new Document("template.epub");
// save EPUB as a DOC"DocOutput.doc", SaveFormat.DOC); 
// load DOC with an instance of Document
Document outputDocument = new com.aspose.words.Document("DocOutput.doc");
// call save method while passing SaveFormat.OTT"", SaveFormat.OTT);   

Open Password Protected EPUB Document via Java

While converting EPUB to OTT, even if your document is password protected, you can still open it using PDF Manipulation API Aspose.PDF for Java . In order to open the encrypted file, you need to create a Document object and open the EPUB using the owner’s password.

Document document = new Document("input.epub", "password");
// save EPUB as a DOC"DocOutput.doc", SaveFormat.DOC);

Save OTT Document to a Database via Java

While saving your input document to OTT file format, you can also save your document to database instead of a file system. You may need to implement storing and retrieving Document objects to and from a database. This would be necessary if you were implementing any type of content management system. In order to save your OTT to database it is often necessary to serialize the document to obtain a byte array. This can be done using Aspose.Words for Java API. After getting your byte array, you can store it in the database using SQL statement.

public static void StoreToDatabase(Document doc, Connection mConnection) throws Exception {
    // create an output stream which uses byte array to save data
    ByteArrayOutputStream aout = new ByteArrayOutputStream();
    // save the document to byte array, SaveFormat.OTT);
    // get the byte array from output steam
    // the byte array now contains the document
    byte[] buffer = aout.toByteArray();
    // get the filename from the document.
    String fileName = doc.getOriginalFileName();
    String filePath = fileName.replace("\\", "\\\\");
    // create the SQL command.
    String commandString = "INSERT INTO Documents (FileName, FileContent) VALUES('" + filePath + "', '" + buffer + "')";
    Statement statement = mConnection.createStatement();

What is EPUB File Format?

An EPUB file, also known as an Open eBook File, is a standardized format developed by the International Digital Publishing Forum (IDPF). It is based on XML (eXtensible Markup Language) and XHTML (eXtensible Hypertext Markup Language). EPUB files are designed for reading digital books and publications on various electronic devices such as e-readers, tablets, and smartphones.

EPUB files consist of three main components. The first component is the spine, which contains the main text of the book and defines the order in which the pages should be read. It provides the structural framework for the content.

The second component is the manifest, which serves as a catalog of all the files that make up the EPUB book. This includes the spine, cover image, table of contents, and any additional content. The manifest ensures that all the necessary files are properly linked and organized within the EPUB package.

The third component is the container, which stores the EPUB files in a compressed format. The container helps reduce file size and enables efficient distribution and storage of EPUB books.

EPUB files can be created using various software programs such as Adobe InDesign, Sigil, and Calibre. These tools provide authors and publishers with the ability to create, edit, and format EPUB books according to the specifications set by the IDPF. With EPUB being an open and widely adopted standard, readers can enjoy a seamless reading experience across different devices and platforms.

What is OTT File Format?

OTT (OpenDocument Template) is a file format used for creating templates in the OpenDocument format. OpenDocument is an open standard for office documents, including text documents, spreadsheets, presentations, and more. OTT files specifically serve as templates for creating new documents with predefined styles, formatting, and content.

OTT files are based on the XML-based OpenDocument format, which ensures interoperability and compatibility across different office suites and applications that support the OpenDocument standard, such as LibreOffice, Apache OpenOffice, and Calligra Suite.

When you open an OTT file, it serves as a starting point for creating a new document. It contains placeholders, predefined styles, and other elements that help structure the content and maintain consistency throughout the document. Users can modify the template as needed, such as replacing placeholders with actual content, adjusting styles, and adding or removing sections.

The advantage of using OTT files is that they provide a convenient and efficient way to create documents with consistent formatting and layout. By starting with a template, users can save time and effort in setting up the document structure and formatting from scratch.

OTT files can be easily shared and distributed, allowing others to use the same template to create documents with a unified look and feel. They also support customization options, allowing users to personalize the template according to their specific needs.
