Jersey, List of Implemeted webservices - java

Just wanted to know, if there is a way, I can find out the list of implemented rest services which are using Jersey.
Thanks

Also can use the following link, it has the nice implementation of dropwizard Michael was talking about
Listing all deployed rest endpoints (spring-boot, jersey)

I suppose you can get the same functionality by using using an Aspect.

javax RS: Check RESTful API peremeter

I am new to java EEE. So many things to learn yet.
I have been developing a webservices where I have been using javax RS. I have created several RESTful endpoints some of them are requires expensive method call. So, I would like to validate the API perematers before further processing.
What are the possible frameworks for parameters? I heard about Jersey. Thank you in advance for help and suggestion.
I have been using JDK 7.
Depends on what you want to validate, Jersey has some tools to validate parameters as shown here Bean Validation Support.

Solution for easy generating rest services?

We have a application which works with MySql database.
Now we are implementing mobile version of our application and I'm looking for java solution for easy generating rest services from already ready sql queries.
Details on security and performance:
Security is required (LDAP).
Performance - working time of rest request should be approximately equals working time of sql request.
What solutions can be used for it?
I think the best solution is REST4Enterprise
also can take a look on and restSQL
I suggest using spring roo very easy to use
I recommend using netbeans to generate rest webservices from database tables.
Netbeans also offers the ability to generate REST webservices from entity beans (JPA entities).
Have a look at this link.
If you are looking for just CRUD REST services - one of the above tools suggested by others can help.
But for something more check - Dropwizard
my 2c
For Mobile applications, REST is the best recommended architecture. But you have to ensure the session handling at the client side (recommended).
Eclipse -> Webservice -->Create a Sample Rest Webservice will be a good starting point
You can use spring-rest or grails to develop rest services.
Consider doing web services in PHP. No need for anything other than Tomcat, and offers LDAP verification. It is very quick time to market, and PHP works with MySql pretty seamlessly.
You can give a look at Developing REST Web Services Tutorial.. not sure if it's the best solution but could be one... I used it twice and found it usefull and really easy.
In the Java™ world, you can build a RESTful web service in several ways: Some folks use JSR 311(JAX-RS) and its reference implementation Jersey, others use the Restlet framework, and some might even implement from scratch. Spring framework for building Java EE applications, also supports REST in its MVC layer.

Calling a soap web service using java

In my java program, I need to call a SOAP web service that is deployed on a remote server.
Looks like there are several different approaches when explored in web.
But I would like to know as what is currently being used more in the developer world.
Also is there is a way to call a SOAP web service using Spring or axis or xfire.
Thanks in advance for your input.
For spring you can look at http://static.springsource.org/spring-ws/site/reference/html/client.html for client information.
When I write SOAP webservices I tend to use jax-ws now, especially since it comes installed with JDK6 now.
For a tutorial on that you can look at http://download.oracle.com/docs/cd/E17802_01/webservices/webservices/docs/2.0/tutorial/doc/JAXWS.html.
I like it since it uses annotations, so is simpler than using axis.
If you are using Spring then using their webservice options would be your best bet though.

Combing Metro and Jersey

I've been at this for a little while and my mind has gone to mush.
I'm wondering if anyone can help me out here. I'm trying to make a Java Web Service (using its own HTTP server and not something like tomcat), that supports Metro and Jersey. This way a client can connect to the web service anyway they want whether it is SOAP or REST.
I've got the metro part down so it can support Doc/Lit wsdls and RPC/lit wsdls but I've having some difficultly understanding the Jersey part so it will support REST/xml and REST/json
Also the idea is that there would be one class where all the endpoint methods are written in and other classes would extend it.
Has anyone used these two combined before? Can you point me the direction of a decent article or do you have an example yourself?
Thanks
Metro is a implementaion of JAX-WS used mainly for WSDL/SOAP based webservices.
Jesery is a implementation of JAX-RS used maily for Restful based webservices.
I have used both in the same project but for different purposes. You can also use apache httpclient for restful services, but jersery provides lot of useful annotations for converting to json, xml etc. Hope it helps.
I am a bit confused about what you mean when you say you want to support Jersey. Jersey is an implementation of JAX-RS (JSR-311). Do you mean you want to support JAX-RS?

Creating a Java based web service

I have a very basic Java based web service requirement. Requirement is very simple, pass some String parameters, save them to database and generate a response ("success", "failed"). There is also a case where I need to return simple XML representation (SOAP message) of a simple Object:
<person>
<name>the name</name>
<address>the name</address>
......
</person>
Our current environment is Windows, Apache Tomcat 5, SQL Server.
I'm new to web services so I'm trying to figure out what technologies I could use to make this work. For example:
Do I really need Apache Axis 2 to implement this or would it be overkill?
I saw a tutorial online where all that was needed to create web service was Eclipse, Lomboz plugin for Eclipse and Apache Tomcat. Will I still need Apache Axis2 if I take this route?
Is it possible for Tomcat to process web service requests messages or do I need third party libraries?
I guess I'm looking for the easiest way to implement this. Thank you.
Do you actually need SOAP support? If you do, Axis is probably your best bet. Otherwise, I'd take a look at Jersey.
If it will be as simple as you have mentioned, why don't you look at RESTful Web Services? You can specify your resource calls through a GET, POST, DELETE or PUT HTTP methods.
There's a blog tutorial on how to achieve this. It also shows you how you can return JSON strings/XML (depending on what you want).
A web framework would make this much easier (and actually maintainable), but you could just write a raw servlet to handle requests. You'll want to use an XML object serialization method, though, or at the very least an xml parsing library.
I think you would need axis for this one. But I'll advice you to look at Apache CXF, if in future you will need more support with web service apps. CXF just like axis2 is an implimentation of jax-ws but with an advantage of supporting jax-rs (rest). This means you can expose both REST and SOAP web service interfaces.
