CMAF5. Dynamic Web Service Client

In the previous article, I covered how to make generic Web Service Server. Now let’s move on to Generic Web Service Client over HTTP/HTTPS. In this article, I will cover two different kinds of Generic Web Service Clients. 

·   With HTTP Client Adapter (e*Way)

·   Java API for Generic Web Service Client

1. Generic Web Service Clients with HTTP Adapter 

• svcWebServiceClient : Multithread Supports
• svcWebServiceClientSequence : Single Thread to support sequential message orders
• svcWebServiceClientSSL : Supports HTTPS protocol

2. Java API for Generic Web Service Client over HTTP - com.wwlee.jcaps.cs.webservice.WebServiceClient
- WebServiceClient API is Java API to invoke any kind of Web Service Server.
- This API also supports SAAJ (SOAP with Attachments API for Java) in order to download and upload file(s) through Web Service.
- Example

private void invokeDirectWebService( com.stc.connectors.jms.Message input, com.wwlee.jcaps.otd.common.eaicommonheader.ServiceInterface otdEAICommonHeaderIn, com.wwlee.jcaps.soap.envelope.Envelope_ otdSOAPEnvelope ) throws Exception{  com.wwlee.jcaps.otd.common.eaisoapcommonbody.SOAPCommonBody otdSOAPCommonBody = new com.wwlee.jcaps.otd.common.eaisoapcommonbody.SOAPCommonBody();  WebServiceClient webService = new WebServiceClient();  String soapAction = otdEAICommonHeaderIn.getWebService().getWebServiceOutbound().getSOAPAction();  webService.setRequestSOAPMessage( otdSOAPEnvelope, soapAction );  String endpointURL = otdEAICommonHeaderIn.getWebService().getWebServiceOutbound().getEndPointLocation();  String timeOutSeconds = StringUtil.setDefaultStringValue( otdEAICommonHeaderIn.getWebService().getWebServiceOutbound().getEndPointTimeoutSeconds(), "10" );  webService.invoke( endpointURL, Integer.parseInt( timeOutSeconds ) );  byte[] soapEnvelopeMessageBytes = webService.getResponseBytesSOAPMessage();  otdSOAPEnvelope = (Envelope_) webService.getResponseOTDSOAPMessage();  webService.getElapsedInvokingTime();  /* Set Invoking Time */ otdEAICommonHeaderIn.getTimeTrackingsHeader().getComponentTimeTracking( countComponentTimeTracking ).setStartInvokingTime( webService.getStartInvokingTime() ); otdEAICommonHeaderIn.getTimeTrackingsHeader().getComponentTimeTracking( countComponentTimeTracking ).setEndInvokingTime( webService.getEndInvokingTime() ); otdEAICommonHeaderIn.getTimeTrackingsHeader().getComponentTimeTracking( countComponentTimeTracking ).setElapsedInvokingTime( webService.getElapsedInvokingTime() );  if (webService.hasFault()) {      logger.error( "+++++ Received Fault Message from WebService : " + otdSOAPEnvelope.getBody().getX__AnyText__( 0 ) + " +++++" );      setEAPReprocess( input, otdEAICommonHeaderIn, "Fault Response Message", "Refer to Fault Message in CMSF" );      logger.warn( "+++++ It will be sent to Common EAIReprocess Project in CMSF +++++" );  } else {      otdSOAPCommonBody.unmarshalFromString( otdSOAPEnvelope.getBody().getX__AnyText__( 0 ) );      String status = otdSOAPCommonBody.getStatus();      if (status.equalsIgnoreCase( "ERROR" )) {          setEAPReprocess( input, otdEAICommonHeaderIn, "ERROR Response", otdSOAPCommonBody.getExceptionInfo().getExceptionMessage() );          logger.warn( "+++++ It will be sent to Common EAIReprocess Project in CMSF +++++" );      }  } }
