[@pritamkumarsingh5318]

Excellent explanations (Y)

[@mayo6587]

I have noticed that using "/" before the path labels is optional. I have been using @Path("messages") and now for the method @Path("{messageId}"). There were no issues

[@vishwanathgajavelly6856]

thanks for sharing broda. I felt the same while I was attending these videos, but implemented only when I read your comment. Appreciate this :)

[@Fernando-gv2vy]

Thanks, this is a good tutorial,

[@aliasgar1648]

SHEER AWESOMENESS!!

[@abhishekmithun4475]

Well you have a incredible talent of making things look so easy.I must I am already your fan.The kind of curiosity you have created for web services esp REST is really commendable job!!! Could you please tell where and when could we find rest video after this ?

[@absolute.explore]

Could you please create one video on how to fetch and write that data to database (like MySQL). I mean yes, we can manually create connection write and execute sql queries, close connection, but how to use Jersey or JEE builded in functionality to work with database, what is the best practice within this type of project, I do not know, may be something like JDBC connections pool, JPA, EntityManager? What is better to use in your project, please guide me?

[@mohammedsardar3779]

Hi Koushik thanks for your efficient effort and time. Do we talk about how do we expose Resource to other user once produced ?? Thanks

[@absolute.explore]

Is it a common practise using Hibernate in these kind of projects?

[@dfghjcvbh]

What if instead of long the there is non-primitive data structure? How will Jersey convert that?

[@prasanjitdas1419]

thank u so much koushik .. i want the source code of programs which u r showing in video.. please let me know hoe can i find it

[@大盗江南]

thank u so much!!!!!!!!!

[@paveltuz8403]

How can I change the XML tag names (the java fileds has independent names)? How can I change the order of XML elements to make them change simple alphabetic order?

[@theamrpi397]

Hi Koushik, Will it be possible to do a XML post video. Right now I am taking the xml as string and parsing it. I am guessing there is an easier way involving JAXB, but the documentation is rather vague. Thanks and Regards, Hari

[@theamrpi397]

***** Thanks Nikhitha, I will try it out.

[@1000LennoX]

Hello Koushik, first of all, thank you for your awesome JAX-RS Tutorials! I have a question, is it possible to handle action-based URIs? In your example you are using the Resourced-based. Greetings!

[@baibhavghimire3827]

Action based URI aren't used in REST design in my opinion

[@gauravsinghal5215]

Hello Koushik, Can you create video series for apache camel with rest services(Microservice). I am facing lots of difficulties in my work. This route buillder, route config are not understandable to me.

[@tatjanaandrjushina3860]

Just in case someone is interested. I kept getting 404 on my attempt to get to the specific message. It turned out there were two reasons behind this. First, there were ambiguous paths (I defined @Path for the class and for the second of two methods, assuming that the first method would take the valued from the class; the assumption was wrong). Second, there was a problem with casting Integer to long and back which Jersey decided to tell me nothing about.

[@LorenzoNeriIstorn]

Following each steps i get this as responde: 400 The request entity cannot be empty. Why?

[@ArunraajSingh]

what if there is ambiguity in @Path{"/{messageId}") and @Path("/{messageName}")?

[@karthikreddy1833]

Hi Koushik, I'm facing difficulty in configuring framework in web.xml file and cxf-servlet.xml, Please upload a video to solve this issue

[@_deepuprem629]

Guys, i'm getting a 404 not found error. i'm guessing, If the URI path parameter cannot be converted to an long, the request is considered a client error and the client will receive a 404, “Not Found” response from the server. --Updated from the original post: As a quick work around to test my changes at this point, i added this and it worked like a charm. but i'm sure it's gonna blow chunks if there's more than one HTTP methods in the class or different set of @PathParams for that matter... @Path("/messages/{messageId}") public class MessageResorce { Please share your thoughts!

[@5uryaprakashp1]

I too faced the same issue, what I did is removed '/' from method level path, it works after that.

[@fanxuanhow]

Hey , your video is very good for beginner as me. I have been inspired much more from it. Could you please provide further tutorial about grab data from couchDB. I have no idea about how to connect couchDB in Eclipse

[@ЦветославЦветков-д7ч]

Keep in mind when you add @PathParam to choose the right one because there are two same classes but in different package, or I could have a problem when you make request to the resource

[@TM-lf6os]

Thanks, I had this issue. Had to erase the @PathParam and re-type and resolved it

[@gcristian1417]

THANK"S A LOT! You saved me !!!!!! :D :D :D :D :D

[@sanketprabhune425]

Hello Koushik, first of all thanks for all your knowledge sharing. While working with tutorial, when i removed that commented out dependency for JSON, my workspace is giving errors and building the application. Failure to transfer org.apache.maven.plugins:maven-resources-plugin:pom:2.6 from repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.6 from/to central (repo.maven.apache.org/maven2): The operation was cancelled. pom.xml /messenger line 1 Maven Configuration Problem this is the error i am getting now. not getting issues for dependency though. Can you or someone here help me out with this ? i have not changed anything in my pom.xml, only uncommented the dependency.

[@adiviswanath]

What if there was one more method ?

[@sathyavathid.a8451]

Hi.. I am getting 204 No content when I go to messages/1 or messages/2. Can anybody please help me on this?

[@TM-lf6os]

I know this i late, but make sure you return the correct media type (xml), also try retyping the @PathParam annotation. There are 2 and its important you select the correct one.

[@ramprodigy7878]

this is fucking awesome

[@puneethshivalingaiah]

:) :) :)

[@НиколайБеляков-ш2л]

So much water! Might have been briefer.
