As the question isn't clear,but it seems like you want to extract value from the tag without using jsp and servlet, and let's just add a couple of more tags for better understanding. This can be done using JSOUP: https://jsoup.org/cookbook/

 String inputTag = "<input type=\"text\"   name=\"n1\" value=\"howru\"/>"
    + "<input type=\"text\"  id=\"textField2\" name=\"n2\" value=\"howru2\"/>"
    + "<input type=\"hidden\"  id=\"hiddenField\" name=\"n3\"value=\"howru3\"/>";

    Document document = Jsoup.parse(inputTag);

    Elements elementByTag = document.select("input[type=text]");
    System.out.println("Element By Tag(First Input Tag--text):" + elementByTag.get(0).attr("value"));
    System.out.println("Element By Tag(Second Input Tag--text):" + elementByTag.get(1).attr("value"));

    Element elementByID = document.getElementById("textField2");
    System.out.println("Element By ID(Second Input Tag--text):" + elementByID.attr("value"));

    elementByID = document.getElementById("hiddenField");
    System.out.println("Element By ID(Hidden Field):" + elementByID.attr("value"));

Output

Element By Tag(First Input Tag--text):howru
Element By Tag(Second Input Tag--text):howru2
Element By ID(Second Input Tag--text):howru2
Element By ID(Hidden Field):howru3
