53. What Is a URL

A URL has two main components:

• Protocol identifier: For the URL http://example.com, the protocol identifier is http.

The name of the machine on which the resource lives.

Filename

A reference to a named anchor within a resource that usually identifies a specific location within a file (typically optional).

54. Creating a URL

The easiest way to create a URL object is from a String that represents the human-readable form of the URL address. This is typically the form that another person will use for a URL. In your Java program, you can use a String containing this text to create a URL object:

getProtocol

Returns the protocol identifier component of the URL.

getPort

Returns the port number component of the URL. The getPort method returns an integer that is the port number. If the port is not set, getPort returns -1.

getFile

Returns the filename component of the URL. The getFile method returns the same as getPath, plus the concatenation of the value of getQuery, if any.

55. Reading Directly from a URL

import java.net.*;

import java.io.*;

new InputStreamReader(

oracle.openStream()));

}

}

56. Connecting to a URL

URL myURL = new URL("http://example.com/");

URLConnection myURLConnection = myURL.openConnection();

58. Introducing JAX-WS

Put succinctly, the JAX-WS architecture is an easier-to-understand architecture for web services development. In previous web services offerings, the functionalities of the earlier JAX-RPC and JAXB APIs overlapped quite a bit. When JAXB 1.x emerged after JAX-RPC, and as data-binding functionality became more comprehensive with enhanced standards such as XML Schema and Relax NG, Java platform developers recognized the need to separate the web services definition from the data-binding components.

59. Java Architecture for XML Binding (JAXB)

But how do you couple these partners in practice? More specifically, how do you access and use an XML document (that is, a file containing XML-tagged data) through the Java programming language? One way to do this, perhaps the most typical way, is through parsers that conform to the Simple API for XML (SAX) or the Document Object Model (DOM). Both of these parsers are provided by Java API for XML Processing (JAXP). Java developers can invoke a SAX or DOM parser in an application through the JAXP API to parse an XML document -- that is, scan the document and logically break it up into discrete pieces. The parsed content is then made available to the application. In the SAX approach, the parser starts at the beginning of the document and passes each piece of the document to the application in the sequence it finds it. Nothing is saved in memory. The application can take action on the data as it gets it from the parser, but it can't do any in-memory manipulation of the data. For example, it can't update the data in memory and return the updated data to the XML file.

62. Search Engine Optimization Process

Website analysis
Before optimizing, a detailed analysis of the web site is very necessary. Content, structure and the target traffic have to be cautiously reviewed.

Identify Business Objectives
One has to be very clear as to what does the business aim to achieve. Your business objectives would vary from generating new leads, to increasing sales. The objective should be kept in mind while looking for the key words.

Position Reports
Pre-optimization as well as a post optimization report should be prepared. The former one is for all the key words you finalized before optimizing and the latter is to record the changes after optimization.

Analysis and Action plan
Analyze position reports of popular search engines. This helps in checking out the action plan. Keeping an eye over position reports is all the more necessary due to consistent changes in the parameters of search engines. You could lose your coveted first rank any moment.
