本文介绍如何使用Java客户端调用PeopleSoft系统的WebService。通过具体示例展示了如何构建SOAP请求、发送HTTP POST请求及解析响应。文中还提供了完整的代码实现，并指出了几个关键步骤。

1、peopleSoft系统webservice发布成功后,会提供一个wsdl URL地址,如：

 http://IP:port/PSIGW/PeopleSoftServiceListeningConnector/PSFT_HR/xxxxx.1.wsdl

 2、利用SOAPUI工具,可查看出SOAP请求XML，
 

 3、java客户端可以模拟SOAP请求，注意以下几点：

 3.1 请求URL地址并非是wsdl地址,而是“
 http://IP:port/PSIGW/PeopleSoftServiceListeningConnector/XXX”

 3.2 请求时需要设置请求的header,SOAPAction=XXXXX,

 3.3 遵循SOAPUI中的RAW窗口展示的请求方式，如下图

 4、代码实现如下:

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.UnsupportedEncodingException;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.methods.InputStreamRequestEntity;
import org.apache.commons.httpclient.methods.PostMethod;
import org.w3c.dom.Document;

public class WebServiceClient {

	public static void main(String[] args) throws Exception {
		test2();
	}

	public static void test2() throws Exception {
		String soapRequestData = "<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' xmlns:bl='http://xmlns.oracle.com/Enterprise/Tools/schemas/BL_MRYSTS_REQAPRVL_REQ.V1'> "
				+ " <soapenv:Header/> "
				+ "  <soapenv:Body> "
				+ "     <parameter> "
				+ "      <bl:EMPLID>10086</bl:EMPLID> "
				+ "      <bl:APRVLSTS>SUB</bl:APRVLSTS>"
				+ "   	 <bl:MRYSTS>S</bl:MRYSTS>"
				+ "  </parameter>"
				+ "  </soapenv:Body>" 
				+ " </soapenv:Envelope>";
		System.out.println("soapRequestData=" + soapRequestData);
		PostMethod postMethod = new PostMethod("http://IP:port/PSIGW/PeopleSoftServiceListeningConnector/PSFT_HR");
		try {
			byte[] b = soapRequestData.getBytes("utf-8");
			InputStream is = new ByteArrayInputStream(b, 0, b.length);
			org.apache.commons.httpclient.methods.RequestEntity re = new InputStreamRequestEntity(is, b.length,"text/xml;charset=utf-8");
			postMethod.setRequestEntity(re);
			postMethod.setRequestHeader("SOAPAction", "BL_MRYSTS_REQAPRVL.v1");
			HttpClient httpClient = new HttpClient();
			int status = httpClient.executeMethod(postMethod);
			InputStream in = postMethod.getResponseBodyAsStream();

			DocumentBuilderFactory bf = DocumentBuilderFactory.newInstance();
			DocumentBuilder db = bf.newDocumentBuilder();
			Document document = db.parse(in);
			String res = document.getElementsByTagName("ResponseInfo").item(0)
					.getTextContent();
			System.out.println(res);
			System.out.println(in);
			System.out.println(status);
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		} catch (HttpException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}

	}

}

5、测试运行环境:

 JDK1.7,

 所需jar包，maven地址如下：

<dependency>
	<groupId>commons-logging</groupId>
	<artifactId>commons-logging</artifactId>
	<version>1.1.1</version>
</dependency>

<dependency>
	<groupId>commons-codec</groupId>
	<artifactId>commons-codec</artifactId>
	<version>1.4</version>
</dependency>

<dependency>
	<groupId>commons-httpclient</groupId>
	<artifactId>commons-httpclient</artifactId>
	<version>3.1</version>
</dependency>
