I want to create a Python RESTful Webservice and Java Webservice Client. I am using Python 2.7. I used web.py to create webservice. On client side (Java) , I want a WSDL file to invoke Python Webservice. Where can I find it? I have configured everything on my laptop.
Update: I refer Python simple example and this doesn't creates it.
Thanks !
Looks like you can always generate a url for the .wsdl file like in this example.
I simply created org.apache.http.client.HttpClient in java to invoke this. Though, I am curious to know wsdl file location.
As #Avenet advised, you can use soaplib, which became rpclib, which in turn became spyne. So check that, please.
People usually use the opposite workflow - they create WSDL manually and than generate stubs of code, so you have a good start, which you than extend with your business logic. Advantage is that it can generate both client and server stubs.
But both workflows should work - generating WSDL from a service, or generating code stubs from a WSDL. For learning purpose I would advice you to create WSDL manually.

I need help of awesome tech people here. I'm trying to understand if I can generate a webservice stubs or class automatically using the wsdl file or is it possible to auto detect the methods or services available on the server side. My web application needs to detect these service methods, type of arguments they accept etc.
I know of some tools like wsdl2java or wsimport, but for this, I need to manually run some commands to generate the client stubs. Instead, I'm looking for a solution, where I can upload the wsdl file to my web application and my application can auto generate the java files, integrate it inside the application and start using it. Not sure if this is possible, but this is my requirement.
Please provide your suggestion or guide me to understand the do's or don'ts here. Many thanks.
take a look to this page :

I'm looking for an easy way to acces wsdl file from java.
In python with suds I can do somethin like:
self.wsdlClient = Client(WSDL_URL)
wsdlClient.methodName()
Is there a way to connect to wsdl through an URL?
Python is a dynamic language so you can create methods on an object on the fly, like for example a method for each operation of your web service as discovered by reading the WSDL. But Java is not a dynamic language so the Python approach can't be used.
You either have to generate the code at design time (i.e. create a stub) by feeding the WSDL to some tool like wsimport.exe (or other tools) then use the generated code in your application or ...
... you have to parse the WSDL at runtime and create the XML payload based on the information you acquired from the WSDL, in which case you might want to look at the following tool: soap-ws.
The easiest way is to generate a stub.
I have a wsdl file, and I want to create a client that will call a service from that wsdl file.
The main issue that the wsdl file has more than 300 method , so using tools to generate client code is not an option , i already tried to use eclipse tools , but the stub class was very big (more than allowed 65536 ).
Any suggestion ?
Thanks
Having a service exposing 300 methods is the problem.
Split your methods across services and you'll be able to use standard tools to generate the client stubs.
I have a public EJB class that I want accessible online as a web service. I have generated a WSDL and the SOAP mesasging seems to work. I used soapUI to test the connection. What I'm not clear about is how would I then use this exposed web service. I'd like to try another language like Python to then make calls through that interface. I know that the WSDL is supposed to help a potential client build it's client side code but I'm not sure about how to specify the connection and location and login information if I had that. I know I'm asking a large topic but any information would help. Thanks
Edit: so basicaly I'm just wondering do I have to use tools to generate my client code from the WSDL like axis2. Or whatever Python uses. Or can I write the code by hand? What's generally done. is the server reference included in that WSDL and are call methods generated usually?
Take a look at ZSI
But ZSI is too complex and spends more time to generate proxies
I suggest you to use suds. suds generates the proxies On the fly and so fast, i used it in some projects.
another packages are available:
soaplib
SOAPy
pysimplesoap
Im a Newbie in wsdl parsing and my information about WSDL is very limited.
I have a scenario in which there is a wsdl file with multiple operations and i want to get the wsdl for a specific operation from that. Is there any libs in java or JS to accomplish such a task . Or am i missing something.
Please correct me if there is anything wrong in the question ,
Thanks in Advance

WSDLs represent a single service with specific operations. Those operations belong to the service can't be separated from the service itself. In order to simply invoke one method you'll have to bind against the entire service (and all other operations and defined types). If you are publishing the operation, you'll have to bind and publish all operations and types defined in the service. There isn't really a way around that.
Now, in your case if you are using java and if you are acting as a client, you can do what Alfredo O alluded to and use a SOAP framework's tooling to generate all of the java client code for you. From there it's just a matter of using the actual service class and invoking the method on that class that corresponds to the method you want to call. You'll have to use the entire wsdl, but from the perspective of your code you won't have to worry about calling any other methods than the one that interests you.
Popular choices for generating a java client for a SOAP service are:
Apache CXF
Metro
Apache Axis2
You can use Axis 2 to auto-generate the java code needed to invoke those operations. Use the wsdl2java tool provided by Axis 2.
