Example of using python to call java Webservice

This article describes how to call java's Webservice using python, including java and python implementation code. For more information, see I. java end
First of all, I use the server and release programs that are compiled by java's webservice support package. the code is as follows.
Webservice interface code:

The code is as follows:

Package com. xxx. test. ws;

Import javax. jws. WebMethod;
Import javax. jws. WebService;

/**
* Created with IntelliJ IDEA.
* User: Administrator
* Date: 14-3-5
* Time: PM
*/
@ WebService (targetNamespace = "http://xxx.com/wsdl ")
Public interface CalculatorWs {
@ WebMethod
Public int sum (int add1, int add2 );

@ WebMethod
Public int multiply (int mul1, int mul2 );
}

Interface implementation code:

The code is as follows:

Package com. xxx. test. ws;
Import javax. jws. WebService;
/**
* Created with IntelliJ IDEA.
* User: Administrator
* Date: 14-3-5
* Time: PM
*/
@ WebService (
PortName = "CalculatorPort ",
ServiceName = "CalculatorService ",
TargetNamespace = "http://xxx.com/wsdl ",
EndpointInterface = "com. xxx. test. ws. CalculatorWs ")
Public class Calculator implements CalculatorWs {
Public int sum (int add1, int add2 ){
Return add1 + add2;
}

Public int multiply (int mul1, int mul2 ){
Return mul1 * mul2;
}
}

Publish the Webservice code :[Code]
Package com. xxx. test. endpoint;
Import com. xxx. test. ws. Calculator;
Import javax. xml. ws. Endpoint;

/**
* Created with IntelliJ IDEA.
* User: Administrator
* Date: 14-3-10
* Time: PM
*/
Public class CalclulatorPublisher {
Public static void main (String [] args ){
Endpoint. publish ("http: // localhost: 8080/test/calc", new Calculator ());
// Endpoint. publish ("http: // 10.3.18.44: 8080/test/calc", new Calculator ());
}
} [/Code]
Run the above code to run your webservice. then you can use Python to test your webservice code.
After the above code runs, you can directly access it using a browser:

The code is as follows:

Http: // localhost: 8080/test/calc? Wsdl

To verify whether the startup is successful.
II. python
The following is the python test code:

The code is as follows:

#! /Usr/bin/python
Import suds
Url = 'http: // localhost: 8080/test/calc? Wsdl'
# Url = 'http: // 10.3.18.44: 8080/test/calc? Wsdl'
Client = suds. client. Client (url)
Service = client. service

Print client

Sum_result = service. sum (10, 34)
Print sum_result
Print client. last_received ()

Multiply_result = service. multiply (5, 5)
Print multiply_result
Print client. last_received ()

Save the preceding code as a webservice. py file, and then modify the executable permissions:

The code is as follows:

Chmod + x webservice. py

The output result is as follows:

The code is as follows:

Suds (https://fedorahosted.org/suds/) version: 0.3.9 (beta) build: R658-20100210

Service (CalculatorService) tns = "http://xxx.com/wsdl"
Prefixes (1)
Ns0 = "http://xxx.com/wsdl"
Ports (1 ):
(CalculatorPort)
Methods (2 ):
Multiply (xs: int arg0, xs: int arg1 ,)
Sum (xs: int arg0, xs: int arg1 ,)
Types (4 ):

III. FAQs

Note: when executing the above code, you may prompt:

The code is as follows:

Traceback (most recent call last ):
File "ws. py", line 1, in
Import suds
ImportError: No module named suds

If the dependent package is missing, we can manually download and install the suds package.

The code is as follows:

Wget http://downloads.sourceforge.net/project/python-suds/suds/0.3.9/suds-0.3.9.tar.gz? R = http % 3A % 2F % 2Fsourceforge.net % 2 Fprojects % 2Fpython-suds % 2 Ffiles % 2F & ts = 1394436413 & use_mirror = nchc
Tar zxvf suds-0.3.9.tar.gz
Cd suds-0.3.9
Sudo python setup. py install

OK.
