Creating a client for a existing web service out of a WSDL file with Java

I have a given WSDL file (a SOAP web service in the internet) and I want to use this service. For that I want to write a Java client, that sends the required datas (as XML) to the web service and the service itself sends an response.
Unfortunately, I am totaly new in web services. This is why I want you to ask for help.
I found a lot of ways to use SOAP in Java. One way is the AXIS2 framework from Apache, another way is the Eclipse Web Tools Project (WTP). I've tried both but couldn't get it run..
First of all.. What do I need to use such an SOAP web service?
I think:
- generate Java source out of the WSDL file
- write an client that uses this code
- with this client you can send datas to the web service (the client itself sends the data via XML) and the client can process the response
Am I right or do I have a fallacy?
Thank you for your help!!

I think: - generate Java source out of the WSDL file - write an client that uses this code - with this client you can send datas to the web service (the client itself sends the data via XML) and the client can process the response
That is correct. You can use Axis2 as you mentioned, write a JAX-WS client, you can even write the SOAP message by hand (not that I would recommend that though).
You should try to get a successful call from SoapUI first then write your client application. Use wsimport to get a simple client working (if that's all you need a framework like Axis2 could be overkill).

Calling tibco webservcie from java client

I have been given WSDL and XSD files for Tibco Web service. Along with that I have Tibco queue details.
I need to hit the Tibco sync queue and get the response from the queue.
My question is hot to create the java stub(client) with appropriate endpoint address.
When I create the stub using CXF, it says "nvalid endpoint address" while I running the stub client.
There is another option to send request to queue using spring's WebServiceTemplate. But to construct the input XML message.
Does any one call the Tibco webservice from Java? Which is the best way?

I think it would be helpful if you post the actual WSDL you have problems with.
I assume the WSDL was generated with TIBCO Businessworks. TIBCO supports exposing WSDL's with JMS Transport bindings a long while in a proprietary way before a SOAP over JMS standard from W3C was defined.
CXF implemented the W3C standard so it won't understand the binding and you ll have to do some hand wiring for the transport of your client like described e.g. here:
http://cxf.apache.org/docs/using-the-jmsconfigfeature.html

Make sure that the problem is actually in the generated client, and not the WSDL or the given endpoint is worng, First try to test the wsdl with SOAP UI or any similar tool.
if it works then you can check what is wrong with the generated client.

Parsing a SOAP response without wsdl using java/php

I wish to consume a SOAP webservice from the Govt. of India public data sets. Here is an sample URL:
http://data.gov.in/sites/default/files/Fish_2013.xml
I have been using REST APIs and have never used a SOAP one.This is a SOAP webservice and it does not give me any information about the wsdl file location. As per my understanding I can generate a client using the WSDL if available and use it but how do I use a SOAP API without WSDL.
Most of the other posts talk about changing the response format but then its not possible in my case.

You can do 2 tricks:
install a local webserver
map the localhost/yourproject?wsdl to that xml file
use a Soap client generator tool on that wsdl link ( some allow other links wich doesn't end at wsdl some doesn't)
use the generated artifacts to consume soap.

How to generate a SOAP request from a WSDL in Android

I have a WSDL file, and also i can retrieve the XSD file as well, in a server. i need to read either WSDL or XSD and generate a SOAP request accordingly in Android.
Thanks !!!

Use can kSoap for SOAP request.Please check my answer to this thread.

Send file with REST?

Do Java REST frameworks like Restlet and Jersey allow one to send a file as input to a web service?
This would encompass the client sending the file and the server then receiving and processing the file.

If you're asking if you can do an HTTP PUT to a Restlet service, then, absolutely, yes you can. You can use the Directory class if you just want to store the file, or you can implement your own ServerResource to handle the new resource.
I haven't used Jersey, but Restlet is a fantastic api.

Well, there's no restriction for them not to do it. REST handles files without any problems.
Take a look at:

You can also use REST Assured which builds on HTTP Client. It's very simple:
given().multiPart(new File("/somedir/file.bin")).when().post("/fileUpload");
