SOAPによるWebサービスの接続

Question

私は、WebベースのWebサービスクライアントを作成して、IPを介して安全なWebサービスを消費しようとしています。これは私の初めてのことですので、ここで深刻な助けが必要です。私のベンダーから得られるのは、3つの異なる.cerファイルとwsdlリンクです。いくつかの調査の後、keytool -import -file myCert.cer -alias testkey -keystore test.ksという新しいキーストアが作成され、これらの3つの.cerファイルが追加されました。次に、私はテストのためのコードの下に書いた。接続に成功するために必要なことがあれば教えてください。

import java.io.ByteArrayInputStream; 
import java.io.StringWriter; 
import java.nio.charset.Charset; 

import javax.xml.soap.*; 
import javax.xml.transform.*; 
import javax.xml.transform.stream.*; 

public class SOAPClient { 

public static void main(String[] args) { 
    String response = null; 
    try { 
     String request = "my xml based SOAP string"; 

     System.setProperty("javax.net.ssl.keyStore", "/web/cert/test.ks"); 
     System.setProperty("javax.net.ssl.keyStorePassword", "password"); 

     // Create SOAP Connection 
     SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance(); 

     String url = "https://example.com:31746/Service/service.serviceagent"; 
     MessageFactory messageFactory = MessageFactory.newInstance(); 
     SOAPConnection soapConnection = soapConnectionFactory.createConnection(); 

     SOAPMessage soapMessage = messageFactory.createMessage(new MimeHeaders(), new ByteArrayInputStream(request.getBytes(Charset.forName("UTF-8")))); 

     // Send SOAP Message to SOAP Server 
     SOAPMessage soapResponse = soapConnection.call(soapMessage, url); 

     // Process the SOAP Response 
     TransformerFactory transformerFactory = TransformerFactory.newInstance(); 
     Transformer transformer = transformerFactory.newTransformer(); 
     Source sourceContent = soapResponse.getSOAPPart().getContent(); 
     StringWriter outWriter = new StringWriter(); 
     StreamResult result = new StreamResult(outWriter); 
     transformer.transform(sourceContent, result); 
     StringBuffer sb = outWriter.getBuffer(); 
     response = sb.toString(); 
     System.out.println(response); 

     soapConnection.close(); 
    } catch (Exception e) { 
     System.err.println("Error occurred while sending SOAP Request to Server"); 
     e.printStackTrace(); 
    } 
    //return response; 
} 

} 

しかし、私は（私はそれをテストする他の方法を持っていないので）、コマンドラインからスタンドアロンとして、このJavaコードを実行したときに、私は、画面上の例外の下に取得します。

Answer 1

をプロパティを変更した後、私は、これは根本的な問題ではないと思いますが、あなたはjavax.net.ssl.trustStoreでjavax.net.ssl.keyStoreを変更する必要があります。

• trustStoreに遠隔 authenticationcredentials（及び従って接続） を信頼すべきかどうかを判断します。

• keyStoreは、 リモートホストに送信する認証資格情報を決定します。

おそらく、エラーはリクエストが有効なSOAPメッセージではないため、サーバーからのヌル応答を引き起こしている可能性があります。

String request = "my xml based SOAP string"; 

は、私はあなたが入れ替わっSOAPメッセージをデバッグ示唆し、代わりに応答するためにゼロから
