Transform MHTML to FLATOPC via Java

On Premise Java API to Render MHTML to FLATOPC without using any third party application

MHTML to FLATOPC conversion can be done in two simple steps using Aspose.Total for Java. Aspose.Total for Java is a comprehensive suite of APIs that provides powerful document processing capabilities.

The first step is to render MHTML file to DOC using Aspose.PDF for Java. Aspose.PDF for Java is a powerful PDF processing API that enables you to create, edit, convert, and manipulate PDF documents. It also provides the ability to render MHTML files to DOC format.

The second step is to convert DOC to FLATOPC using Aspose.Words for Java. Aspose.Words for Java is a powerful document processing API that enables you to create, edit, convert, and manipulate Word documents. It also provides the ability to convert DOC files to FLATOPC format.

By using Aspose.Total for Java, you can easily convert MHTML to FLATOPC in two simple steps. Aspose.PDF for Java can be used to render MHTML files to DOC format and Aspose.Words for Java can be used to convert DOC to FLATOPC format. This makes it easy to convert MHTML to FLATOPC without any hassle.

Java API to Convert MHTML to FLATOPC

Open MHTML file using Document class
Convert MHTML to DOC by using save method
Load DOC file by using Document class of Aspose.Words
Save the document to FLAT_OPC format using save method and set FLAT_OPC 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 MHTML file with an instance of Document class
Document document = new Document("template.mhtml");
// save MHTML as a DOC 
document.save("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.FLAT_OPC
outputDocument.save("output.flat_opc", SaveFormat.FLAT_OPC);   

Open Password Protected MHTML Document via Java

While converting MHTML to FLATOPC, 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 MHTML using the owner’s password.

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

Save FLATOPC Document to a Database via Java

While saving your input document to FLATOPC 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 FLATOPC 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
    doc.save(aout, SaveFormat.FLAT_OPC);
    // 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();
    statement.executeUpdate(commandString);
}
