| webservice with perl | webservice | ||
好久没有没有来javaeye涂鸦源码了，太忙了，真的太忙了，不过这次带来些和webservice有关的东西。不是用 java 的axis、xfire、cxf、也不是用 c 的gsoap，而是用 perl 的SOAP::Lite。这个绝对是懒人做webservice的最佳工具。当然、这是在脱离现有系统环境的前提下说的。废话不说，直接上源码。
==========客户端代码==========
#! /usr/bin/perl
use SOAP::Lite;
my $service = SOAP::Lite->service('http://127.0.0.1:8080/services/TestService?wsdl');
my $result = $service->getResult(1,"123");
===========================
这个就是用perl实现webservice的客户端源码。简单吧，O(∩_∩)O哈！

第一篇在javaeye的blog，希望只是能得到共享。本文主要目的是实现功能。对gsoap的安装和wsdl2h、soapcpp2 的使用不做介绍，因为gsoap不属于java范畴，而且也确实比较简单。
一. 下载，安装gsoap
二. 开发
1. ws.h
//gsoap ns1 service name: WSName
//gsoap ns1 service type: WSType
//gsoap ns1 service port: http://localhost
//gsoap ns1 service namespace: http://namespace
//gsoap ns1 service transport: http://schemas.xmlsoap.org/soap/http
int ns1__getVersion(
char*,
char**
);
1.1 用soapcpp2生成代码
2. server.c
int main(int argc, char **argv){
//soap_serve(soap_new());
SOAP_SOCKET m, s;
struct soap soap;
soap_init(&soap);
soap_set_mode(&soap, SOAP_C_UTFSTRING);
if(argc < 2){
soap_serve(&soap);
}else{
m = soap_bind(&soap, NULL, atoi(argv[1]), 100);
if(!soap_valid_socket(m)){
soap_print_fault(&soap, stderr);
exit(-1);
}
fprintf(stderr, "Socket connection successful: master socket = %d\n", m);
for(;;){

2.1编译程序并运行
3. Test.java
import org.apache.axis.client.Service;
import org.apache.axis.client.Call;
import javax.xml.namespace.QName;
public class Test {
public static void main(String[] args) throws Exception {
process();
}
public static void process() throws Exception {
Service service = new Service();
Call call = (Call) service.createCall();
Object[] paraObject = new Object[1];
paraObject[0] = "你好";
String strServiceUrl = http://localhost; //gsoap ns1 service port
call.setOperationName(new QName("http://namespace", "getVersion")); //gsoap ns1 service namespace
call.setTargetEndpointAddress(new java.net.URL(strServiceUrl));
Object ret = call.invoke(paraObject);
System.out.println("ret = " + ret);
}
}
3.1 编译运行

| CORBA with JAVA server and Python client | python | ||
最近在玩CORBA，java做的server端，python做的客户端，功能嗷嗷easy。需要注意的地方用红色标记了。下边上代码。
1.首先，我们写一个Arith.idl，简单说明一下，module叫Arith，里面有两个接口一个是Calc，另外一个是Temperature
module Arith {
interface Calc {
void plus(in double x, in double y, out double result);
void minus(in double x, in double y, out double result);
void multiply(in double x, in double y, out double result);
void divid(in double x, in double y, out double result); // raises (ZeroDivision);
};
interface Temperature {
double CelsiusToFahrenheit(in double celsiusDegree);
double FahrenheitToCelsius(in double fahrenheitDegree);
};
};
2.然后是server端的代码
idlj.exe -fall Arith.idl
import org.omg.CosNaming.*; // naming service
import org.omg.CosNaming.NamingContextPackage.*;
import org.omg.CORBA.*;
import org.omg.PortableServer.*;
import org.omg.PortableServer.POA;
import org.omg.CosNaming.NamingContextPackage.*;
import org.omg.CORBA.*;
import java.util.*;
import Arith.*; // the package containing the stubs
// and skeletons
public class Server {
public static void main(String args[]) {
try {
// create and initialize the ORB
String[] parameters = new String[]{ "-ORBInitialPort", "900","-ORBInitialHost", "localhost"};
ORB orb = ORB.init(parameters, null);
// get reference to rootpoa & activate the POAManager
POA rootpoa = POAHelper.narrow(orb.resolve_initial_references("RootPOA"));
rootpoa.the_POAManager().activate();
// create servant and register it with the ORB
CalcServant servantImpl = new CalcServant();
servantImpl.setORB(orb);
TemperatureServant tempImpl = new TemperatureServant();
tempImpl.setORB(orb);
// get object reference from the servant
org.omg.CORBA.Object ref = rootpoa.servant_to_reference(servantImpl);
Calc calcRef = CalcHelper.narrow(ref);
org.omg.CORBA.Object ref2 = rootpoa.servant_to_reference(tempImpl);
Temperature tempRef = TemperatureHelper.narrow(ref2);
// Get the root naming context
org.omg.CORBA.Object objRef = orb.resolve_initial_references("NameService");
NamingContextExt ncRef = NamingContextExtHelper.narrow(objRef);
// Bind the object reference in naming
// add more
String name = "Calc";
NameComponent[] nc = ncRef.to_name(name);
ncRef.rebind(nc, calcRef);
name = "Temp";
NameComponent[] nc2 = ncRef.to_name(name);
ncRef.rebind(nc2, tempRef);
System.out.println("server started....");
// Wait for invocations from clients
java.lang.Object sync = new java.lang.Object();
synchronized (sync) {
sync.wait();
}
} catch (Exception e) {
System.err.println("ERROR: " + e);
e.printStackTrace(System.out);
}
}
}
3.下面就是python写的客户端代码了，O(∩_∩)O哈！这里提一下，我们用到了omniORBpy-3.4-python2.5
