Example of using python to call java Webservice

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:
Copy codeThe 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:
Copy codeThe 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:
Copy codeThe 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:
Copy codeThe 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:
Copy codeThe Code is as follows: chmod + x webservice. py

The output result is as follows:
Copy codeThe Code is as follows: Suds (https://fedorahosted.org/suds/) version: 0.3.9 (beta) build: R658-20100210

Note: When executing the above Code, you may prompt:
Copy codeThe Code is as follows: Traceback (most recent call last ):
File "ws. py", line 1, in <module>
Import suds
ImportError: No module named suds
If the dependent package is missing, we can manually download and install the suds package.
Copy codeThe 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.
