URL引数を使用した動的Webサービス呼び出し

Question

クライアントを作成せずに既存のWebサービスを呼び出す必要があります。私は以下のような動的クライアントを生成するためにAXIS Apacheを使用しました。

try { 
     Service service = new Service(); 
     Call call = (Call) service.createCall(); 
     call.setEncodingStyle("targetNameSpace"); 

     call.setTargetEndpointAddress(new java.net.URL("WSDLURL")); 
     call.setOperationName(new QName("targetNameSpace", "runJob")); 

     call.addParameter("arg0", org.apache.axis.Constants.XSD_STRING, javax.xml.rpc.ParameterMode.IN); 

     call.setReturnType(org.apache.axis.Constants.XSD_STRING); 

     String result = (String) call.invoke(new Object[] {"--context=Tokens"}); 
     log.info("result: {}", result); 
     if (!result.equals("0")){ 
      throw new MosApplicationError("Job Failed "); 
     } 

    } catch (Exception e){ 
     throw new MosApplicationError("Talend job failed", e); 
    } 

私のwsdlは、リクエストとレスポンスの両方のオブジェクトに対して文字列以外を使用しません。このコードを実行すると、次のエラーが表示されます。

誰もが考えていますか？軸のバージョンは1.4とjdk 1.6

ありがとうございます。

Answer 1

問題が見つかりました。以前は、WSDLファイルを正しく読み取ることができませんでした。私のwsdlは文字列の配列を返していましたが、上のコードでは文字列の配列ではなく文字列として戻り値の型を定義していました。だから、これらの2行を追加すると、私の問題は解決しました:)

 //Return object is array of string 
     call.setReturnType(Constants.SOAP_ARRAY); 
     //Added to marshal and de-marshal the array of string 
     call.registerTypeMapping(String[].class, new QName(talendApplicationName,""), ArraySerializerFactory.class, ArrayDeserializerFactory.class);
