    Dear ankush,
    i m really very thankful 2 u. just by going 6 videos of yours i got good command and got the right way to proceed regarding webservices. if u dont mind can u please suggest me about JAXP,JAXB,JAX-WS,JAX-RPC. I am completely confused about it , where to start and how to use . please suggest .
    thanx a lot

      Hi Arvind, thanks for liking all the web services video tutorials..

      JAXP is the java API for XML processing. Its used to validate and parse the xml documents.

      JAXB is again a JAVA API and is used to convert a XML to Java objects and vice versa.
      For more info on this.. go through JAX-B

      JAX-RPC is a Java API which allows a Java application to invoke a Java based web service only.
      JAX-WS 2.0 is the successor of JAX-RPC 1.1; so, You may treat JAX-RPC as the older version of JAX-WS.

      JAX-WS is a Java API which provides support for creating web services (typically SOAP based i.e an XMl based message protocol)
      However, the same API may be used to develop web services for REST architectural style too which is a little complex in some cases
      (you may treat it as an advance thing to know about) Also see, JAX-WS ( SOAP Based)

      JAX-RS is a Java API which provides support for creating web services according
      to the REST (Representational State Transfer) architectural style. Also see, JAX-RS ( REST based)

      JAXB stands for
      1. Java API (Application Programming Interface) for XML (Extensible Markup Language) Binding
      2. Java Architecture for XML Binding

      JAXB Adds support for data binding using the Java Architecture for XML Binding (JAXB).

    I loved the way you are delivering the concepts and it helped a lot.
    It would be very helpful if you can give detail info on the Web Services with more examples .
    I am em phasing on JAX B and JAX WS .If you could give examples how they are implemented like creating a WSDL and how it is being used in the application and how we are sending the request and getting the response in the applications.The implementation for all of the above would be very helpful .

    Thanks a lot 🙂 🙂

    You did a very good job and I really appreciate the videos and the way you give the explanations. It is very clear. However I have some suggestions: some topics should be addressed. There are a lot of video tutorials on the internet but it is really rare to find one that tackles security, exception handling. I would suggest when you create a series to include Security videos as well.

    Dear Ankush Gaurav JI,

    I was searching for Spring MVC tutorials on YouTube. Fortunately I found that your video series lectures are worth watching.
    I’d like to say that your lecture series is one of the best lectures I have ever seen so far.
    You have explained every topic very nicely.
    You have articulated every thing with smooth transition and with good oratory power.

    I am thankful to you for serving noble cause kind of act for students and all amateur learners.
