I have a web application java in internet and a web service (SOAP) in intranet. I need to call only two of method web services..
What is the best way to do this? I have to guarantee the necessary security because the APPLICATION is on the internet but I can not allow free access to the intranet or access to the web service and all its methods. How to do it?
How do you invoke web services from the backend ?
HELP ME PLEASE.
As i know SOAP allow you to use Statefull. Some info
So you can use JAAS for that, see here

I have created REST web service in java but need to secure it so that only the authorised clients should be able to access the service. I have never implemented security before. Hence I have no idea where to start to be honest. Do I need to implement any token based security where client need to provide the token in the header of request and I need to verify on my end ?
As RESTful Web Services work with HTTP URL Paths, it is very important to safeguard a RESTful Web Service in the same manner as a website is secured.
For understanding of importance of security consider the following links:

While for Implementation using Spring use the given link:

I am new to web services and studing Jax-WS web services these days. I created a little web service and host it in tomcat server and created a java web service client for accessing the service as well. But I am having a little confusion in the web service client, because in the client we generate a stub for accessing the service.
Here is it using RMI for invoking the web service???
According to my knowledge tomcat is a web container and it is not supporting for RMI.
I searched this through the internet and I was unable to find the clear answer. Can anybody please simply explain me how does it happen.
If the tomcat is not supporting to RMI how does it invoke the web service. I have this confusion since it uses the stub that we generated using wsimport command.
thanks a lot
Here is it using RMI for invoking the web service???
Http. The web service client would create a http request (just like how a browser does when you request a url), convert your request object to an xml payload and invoke your service end point. Different vendors of JAX-WS may use different implementations, but it is usually some form of HttpURLConnection
HttpClient is a popular package to create Http connections from a java program.
I have some doubts regarding web application integration. So Please suggest me possible ways for implementing below functionality.
Lest's say I have one web Application(WebApp1) in Java/.net/PHP and Second web application(WebApp2) in Java. Both web application is deployed on different web servers. and uses the one common database. One web application(WebApp1) has only login form and other web application(WebApp2) has game module. now when User log in from one web Application(WebApp1) with correct credential then it should redirect to other web application(WebApp2).
So Please suggest me how to implement this functionality.
Thanks.
What you need is to implement SSO between your .net/php app and java app, one way to do it is using CAS server .

I know how to make web application in technologies like jsp/servlets and applications servers.
Suppose I make some utility method for particular application say ‘A’ and its working fine no any other web or desktop application in need of this method.
Same thing I can provide such utility method via web service like Rest/Soap.
So why I need web service in this scenario, I can imagine if such service is useful for other application and we provide it as web service then its fine.
Can anyone give me some answer which clear my doubt?
Thanks
Based on Your Comment, i would like to clarify.
Web service is a concept in which you expose a utility or functionality to the world.
Any one in the world can access the same by first establishing ground rules as in SOAP via WSDL.
The Services can serve any number of requests from any application provided it sends the proper input request needed by your service.
In case you have built an application A with a utility functionality X,
Then application B,C,D and so on can access the Web Service.
All it needs is:
the URL for the Service which is exposed through network to the consuming application
The requested parameter format
and the Proper Response format.
Once this is setup, any application, not just in java, can access the service so even .Net applications or PL/SQL applications can access the Web Service Utility.
We are developing a java application which provide web services through SSL. This application is running in Tomcat server.
The purpose of web services is insert, update and select data. So under web service tier is implemented backend tier, which provide access to database.
Suddenly we were asked to build swing application which will also access the data in database. We want to use the same backend (exactly the same runtime) which is used for web service application. How to reach this goal?
I see following possibilities:
use web app instead swing application, which will be part of the same project like web service application and then it will be able to connect backend
Provide some extra web services for swing application only.
Use JMX. It is possible run JMX on Tomcat. Backend could provide functionality through JMX and Swing application could connect it.
Each of these possibilities have advantages and disadvantages. We followed solution 3 and I think it wasn't a clever selection. JMX has problem with generics, you can run only one JMX on tomcat etc.
Java world is rich and there should be some optimal solution for this situation. Could you help?
Add a web service client to the Swing app and let it make exactly the same calls to web services that a browser based UI would.
You're certainly free to add extra, Swing-only web services if you choose.
I didn't think JMX was anything other than a way to allow you to monitor MBeans using a JConsole. What does that have to do with Swing?
