Apache Tika + J2Html +Bootstrap + Java

I was just taking a look at Apache Tika today and because of this I had a chance to brush up my HTML and Regex

I used a library called J2HTML  which really made my output easier to handle, Apart from this I used Bootstrap to make my table look neater.

I ended up with the below kind of look and feel 

The Columns are as below 

1. File Name along with the link. \

2. File Type String 

3. Metadata Table - All metadata elements pulled out by Tika

4. Categories - Basically Tags. - Right now it is very rudimentary but will improve it soon - These categories are arrived by analysing the content of the files. 

Below is the code that is used to parse a file 

Parser parser = new AutoDetectParser();
BodyContentHandler handler = new BodyContentHandler();
Metadata metadata = new Metadata();
FileInputStream inputStream = new FileInputStream(file);
ParseContext context = new ParseContext();



Once the above code is executed.  handler.toString() can be used to get the textual content of the file. 






Below is the code that draws the Table 

String page = html()
        .with(
                head().with(title(pageTitle),
                        link().withRel("stylesheet").withHref("Stylesheet.css"),
                        link().withRel("stylesheet").withHref("http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"),
                        script().withSrc("https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"),
                        script().withSrc("http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js")
                ),
                div().withClass("container").with(h2(headerTitle)),
                body().with(div().withId("header").with(h1(pageTitle)))

.with(table()

.withClass("extra-table-padding table table-responsive table-inverse table-hover table-bordered")

.with(thead().withClass("thead-inverse")

.with(tr().with(th("File Name"), th("Type"), th("Metadata"), th("Category"))))

.with(tbody().with(rows)), footer().withClass("footer")

.with(label(footerTitle)))).render();




PrintWriter out = null;
try {
    System.out.println(location.getFile());
    File htmlFile = new File("G:/Dropbox/Innominds/TikaSample/Results.html");
    out = new PrintWriter(htmlFile);
    out.println(page);
    Desktop.getDesktop().browse(htmlFile.toURI());
} catch (FileNotFoundException e) {
    e.printStackTrace();
    System.out.println("FileNotFoundException - " + e.getMessage());
} catch (IOException e) {
    e.printStackTrace();
    System.out.println("IOException - " + e.getMessage());
} finally {
    out.close();
}
