今天被一個問題搞得挺郁悶得。整整弄了一天也沒有得出個結果。項目中要調用一個webservice，
傳入一個姓名，輸出一串字符串。之前我也沒有太多經(jīng)驗，網(wǎng)上找了些許資料，大概得參考了一下，自己
編寫了幾個類。大致如下：
package cn.sh.ideal.util;
import java.io.*;
import java.net.*;
import javax.xml.parsers.*;
import org.w3c.dom.*;
public class RTXWebservice {
private static String getSoapRequest(String name){//name為要查詢的人名
try
{
Class cls=Object.class;
FileReader isr = new FileReader("../src/cn/sh/ideal/xml/rtxsoap.xml");
BufferedReader reader=new BufferedReader(isr);
String soap="";
String tmp;
while((tmp=reader.readLine())!=null)
{
soap+=tmp;
System.out.println("soap1:"+soap);
}
reader.close();
isr.close();
return soap.replaceAll("name",name);//用傳入的參數(shù)name替換原來xml中的name
}
catch (Exception ex)
{
ex.printStackTrace();
return null;
}
}
/*
*返回InputStream是因為w3c DOM中Document的parse方法可
*以接受InputStream類型的參數(shù)，方面在下一步對XML的解釋
*/
private static InputStream getSoapInputStream(String name)throws Exception
{
try
{
String soap=getSoapRequest(name);
if(soap==null)
{
return null;
}
URL url=new URL(ServiceURI);
URLConnection conn=url.openConnection();
conn.setUseCaches(false);
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestProperty("Content-Length", Integer.toString(soap.length()));
conn.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
conn.setRequestProperty("SOAPAction","\"
http://tempuri.org/GetRTXSessionKey\"");
OutputStream os=conn.getOutputStream();
OutputStreamWriter osw=new OutputStreamWriter(os,"utf-8");
osw.write(soap);
osw.flush();
osw.close();
InputStream is=conn.getInputStream();
return is;
}
catch(Exception e)
{
e.printStackTrace();
return null;
}
}
/*
*用W3C DOM對返回的XML進行解釋
*@param name String 姓名
*@return String rtxSessionKey
*/
public static String getRTXSessionKey(String name)
{
try
{
Document doc;
DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db=dbf.newDocumentBuilder();
InputStream is=getSoapInputStream(name);
doc=db.parse(is);
NodeList nl=doc.getElementsByTagName("GetRTXSessionKeyResult");
Node n=nl.item(0);
String rtxsessionkey=n.getFirstChild().getNodeValue();
is.close();
return rtxsessionkey;
}
catch(Exception e)
{
e.printStackTrace();
return null;
}
}
private void jbInit() throws Exception {
}
}
rtxsoap.xml文件如下：
我先把webservice得wsdl文件找到
把request部分得xml粘貼下來保存在一個rtxsoap.xml得文件中并放到根目錄＋\src\cn\sh\ideal\xml\文件
的一個GetRTXSessionKey方法的。根據(jù)wsdl文件中的request和response的xml文件我寫了上面的
方法。剛開始我用InputStreamReader isr=new InputStreamReader(cls.getResourceAsStream("../src/cn/sh/ideal/xml/rtxsoap.xml"))這種形式去找rtxsoap.xml文件作解析，想把參數(shù)弄進去，然后生
成個新的request的xml發(fā)給webservice來獲取響應，可就是怎么也找不到那個rtxsoap.xml（它明明就是在那里
，可就是找不到，換了很多路徑都是不對，估計問題還是處在路徑上）后來換用 FileReader isr = new FileReader("../src/cn/sh/ideal/xml/rtxsoap.xml");方法。這下能夠讀到rtxsoap.xml了。但是一到要與服務器用soap通信
的時候就報錯誤了，如下：

找了好久，試了n此也沒有解決。其實jbuilder是可以用wizzard來自動的加載一個webservice的（就像.net一樣點幾下就ok了）
不過項目經(jīng)理說這樣不太好，部署的時候要對axis作配置，可能不太方便。所以還是卡在上面的問題上了。希望有高人能幫
我看看，到底是哪里除了問題。我也會繼續(xù)的研究下去，爭取早日給自己一個答案。
