This may sound like a dumb question but i am new to web services.
I followed this tutorial and successfully created a Calculator web service up to the point where i created a local client application that consumed the web service method (A java class with main method which calls the web service method).
My question now is how can i access this method via my browser and set the parameters there, just get an XML/JSON result.
My guess is that i am missing something and i have to publish the web service somehow.
Any solutions, links are highly appreciated.
You have hosted your webservice on glassfish server. Now you want to consume it using internet browser like you did it using test webservice option in net beans.
That means you need to built your own client which runs on web browser.
You need to built a webpage having two input fields in it and a button as result and whenever you hit this button call your webservice and display it's result. You can follow any simple tutorial of web client or application and again you can deployed it on glassfish or apache server.
Also you can use soapui (a client to consume web services) to import your wsdl and access its methods, providing inputs and get result in form of soap.

i have inherited a java app that integrates with desktop QB. There's something in the structure of this whole setup i'm not understanding. This is my first go with the QB api as a developer.
the QB Web Connector 2.2.0.71 is installed and functional. I see the .qwc file and understand it, and it is loaded into the web connector. There is an Application class that publishes an endpoint to the same URL as in the .qwc file and then starts a class named QBWebService. this web service class implements com.intuit.developer.TroubleshootWebServiceFSSoap and has methods authenticate, sendRequestXML, etc. Method sendRequestXML has the code i am testing and attempting to modify. but, before i can do that i need to understand the XML going back and forth.
since i don't know what i don't know, if i'm asking the wrong questions, by all means, please say so.
is it correct, then, that the web connector (on schedule) launches the application class and calls the sendRequestXML method?
i was expecting to find a URL that i could send XML to with something like SOAPui in order to test the XML and examine the response, but that doesn't seem to be how this web service works. is it possible to set it up this way?
perhaps i don't understand what the QB web connector application is doing. what is the purpose of opening up the URL on localhost if it can't accept XML via POST?
thanks in advance for the help

Yes, that's correct.

You can send requests to your SOAP service (e.g. you can call the sendRequestXML method for example).
You'll get back an XML response that (if you were the Web Connector) you would then relay to QuickBooks. QuickBooks would process the response, and then call the receiveResponseXML method to send the XML response back up to your web service.
perhaps i don't understand what the QB web connector application is doing.
It sounds like you're expecting QuickBooks to provide a SOAP endpoint, which you can then directly send XML requests to to query data directly from QuickBooks.
This is not really how the Web Connector works. The Web Connector sort of works "backwards".
Instead of connecting directly to QuickBooks, the Web Connector connects to you (your SOAP endpoint) and asks you "Hey, give me something to do!" (i.e. send me the request XML you want to run against QuickBooks). You then give it an XML request, which it runs against QuickBooks, gets the response, and then connects to you again and says "here's what QuickBooks responded to your request with" (i.e. here you go, receive this response XML from QuickBooks).
So the Web Connector essentially polls a SOAP endpoint you provide, asking you to give it XML requests to pass through to QuickBooks.

I have a requirement to call 52 web services from one java project and this number will increase with time. I am using netbeans 7.3 as development tool. One way to do it is right click project and add web service reference for each service. It is not feasible because for every new web service I will have to add a new reference and redeploy the code. Also all these 52 web services will be calling each other so I will have to enter references for each web service in every other service if I go for this approach.
I hope I have explained the scenario. Now I will ask the question. If I have a url to wsdl file e.g. http://webservices.oorsprong.org/websamples.countryinfo/CountryInfoService.wso?WSDL and I know which method in this web service I need to call, is there a way to parse this wsdl dynamically to create proxy client and after that call a specific method in that web service? I have come accross javaxt API http://www.javaxt.com/javaxt-core/Web_Services which intends to do exactly the same but it is not working properly.
To sum up the question - If I have the wsdl url and I don't want to create compile time stubs but know which methods in that url take what inputs and return what values, can we do it?
The javaxt-core library should work. There was a release published 2/24 (version 1.6.0) that includes several updates to the javaxt.webservices package. More information can be found here:

I have a mock web service running in soapUI 4.5.1 which looks up peoples names and addresses. I have a large dataset of names and addresses in a .txt file which I need to search for and verify with the web service.
The idea is to produce a count of the names which are valid and invalid.
I've created a Netbeans project to code a file reader to read in the text file and I need to connect to the web service to perform a bulk search.
Does anyone know a good tutorial to follow? Or suggestions of the best way to approach the problem? I've looked all over the internet, but I'm not too sure what I'm looking for..
Thanks!
Your requirement as far as I understand:
"Read a name and address from a text file and send them to a web service to verify"
1) If you DO NOT want to use a Java EE container then read this:
http://today.java.net/pub/a/today/2007/07/03/jax-ws-web-services-without-ee-containers.html .... as mentioned here jax-ws-web-services-without-ee-containers
The only difference in your case will be that you will use SoapUI to interact with the endpoint.
2) If you want to use a Java EE container, which is available free with NetBeans if you have the free enterprise download of it.
The way I will do it; I will have a web service running on a server. I'll connect to the web service from SoapUI. I will send a username/address and the web service will return something for example a string "valid" or "invalid". So the mock code is on the server not in soapUI.
Since you are using NetBeans, you should create a web service using NetBeans;
http://netbeans.org/kb/docs/websvc/intro-ws.html
Develop a SOAP based web service and connect to it with SoapUI. The web service is where your MOCK code will go, making it a MOCK Service which you can replace with real code afterwards.
You can put your file on the server or make it part of the application as a property file. In that case, create a web service on server that will verify the name/address list and send you back a count of valid and invalid.
If the data is too huge and you want to keep it on a local file on your machine, then you need to use jax-ws clients appraoch. You will read the data file in a class and then use the clients to send one at a time to the web service and keep a valid/invalid count.

i have created a Java Restful Web service. Now i want to access it in Android. There are different methods in Webservice. Web service is running on http://192.15.10.62:8080.
how should i call a method named getGreetingMsg() in webservice which take a string argument and return a simple String message.
Web service Details
Project name RestFulWS
package Name rest.ws.server
class Name helloAndroid
Method Name getGreetingMsg(string argument)
any help will be appreciated.
Simply with an HTTP client like AndroidHttpClient.
EDIT: RESTful web service is accessible through URL like:
http://yourserver/someservice/<categoryID>/<objectID>
So, you can test your webservice from a web browser like Internet Explorer or Mozilla Firefox.
Then, on Android, use HTTP Get request and the AndroidHttpClient.
Don't forget to set the INTERNET permission in your AndroidManifest.xml too
It depend on the Web server you are using because each type of server will have its own URL to service hosted on it. If you are using JBOSS server then your URL looks like this
IP:PORT/projectname/webservicename/method name
Sounds like you're not sure how to approach your own API. If your API supports GET, then open a web browser and try some GET commands. Once you have a GET statement working, work through this tutorial: http://sarangasl.blogspot.com/2011/06/android-login-screen-using-httpclient.html.
Once you're set with POST, turn off GET in your webserver.
Good luck!

I'm absolutely new to GWT, java and eclipse, but I'm an experienced MS programmer.
I installed eclipse and GWT and created a default project (called it test2) with pre-built sample gwt code. It comes with one java web service on the backend called 'GreetingService' which has a single web method called 'greetServer' that takes a single parameter called 'input'. I tried to invoke it in the web browser with many different combinations, but with no success (my project name is called 'test2):
http://127.0.0.1:8888/test2/greetServer?input=hello
http://127.0.0.1:8888/greetServer?input=hello
http://127.0.0.1:8888/test2/greetingService/greetServer?input=hello
http://127.0.0.1:8888/test2/greetingService?input=hello
etc
but I get http error 404 not found.
My question is, how can I invoke the web service from a browser and see the return data? I know this can be done easily with WCF or asmx web services but I'm not familiar with java web services.
Thanks a bunch!
The GWT Remote Service Servlet only uses HTTP Post. If you want to see the data (which will be encoded by gwt anyway) use could use firebug and take a look at the traffic.
The greeting service isn't intended to be a web service. It's a demo of GWT's remote procedure call (RPC) facility over AJAX. As with most RPC frameworks, the server side is only intended to be called from the generated client stub.
