Help Needed (Desperate Student :(! ) Glassfish/Restful Webservice

[batman400]

Hi guys,

Quickly to explain what im trying to do,

- GOAL -
Create a Restful webservice with a persistent unit backend (mySQL server) which will produce JSON & XML objects, using glassfishv3 via Netbeans IDE 6.9.

I've been using the Wizard netbeans provides to setup this webservice.

To give a clear idea of what i have done already or tried ->

- I've followed numerious tutorials on setting up restful webservices
- I've established a connection in netbeans itself between my setup mySQL server and netbeans, and can view the tables + data.

- I've included the Jar connector etc
- I've updated Netbeans + glassfish
- Ive tried numerious connection source types,
- I've tried using an oracle database ( in college environment which was blocking my access to database).
* Ive opened the ports in windows aswell
* Ran as admin etc
*No Anti Spyware/virus

Anyway when I test the web service it launches into the web browser and lets me type in a hotel id , but when i click enter to try retrieve using the automatically generated get method, it crashes and i get the following error(s) in glassfish console

- " SEVERE: Mapped exception to response: 500 (Internal Server Error)"

- "SEVERE: A message body writer for Java class converter.HotelConverter, and Java type class converter.HotelConverter, and MIME media type application/xml was not found
SEVERE: The registered message body writers compatible with the MIME media type are: application/xml ->"

I'm totally at my end with this, I've tried my best and spent over a week of nonstop hard work trying to overcome this problem. (im new to netbeans + webservices etc). I cannot move on in my project without this aspect of the backend being complete, I would hugely appriciate any Insight or advice/ guidance into a solution or possible alternative methods of carrying out the task.

THANKS GUYS!!!!!!!!!!!!!!!!! <3

I remember running into this but I can't remember the solution. However,
a Google search on "message body writer GlassFish NetBeans" gives this link:
http://jersey.576304.n2.nabble.com/JsonMessageWriter-not-working-under-Netbeans-6-9-1-td6005749.html
I seem to remember I did something much simpler, though. Maybe just
manually added some Jersey libraries to classpath.
I would try NetBeans 7.0rc1 or daily build with GF 3.1 if I were you.
I wouldn't worry about the connector or the database, I don't think
that's where the problem is. Entity classes on NB and MySQL should work
completely by default.
