I have a developED a REST Api with Java and one of the service needs to make a SOAP call to an endpoint. For this I implemented SAAJ client to create the whole xml message. However each time a call consume extra 1 MB of memory.
import javax.xml.soap.*;import javax.xml.transform.* import javax.xml.transform.stream.*;
public class SOAPClientSAAJ {
public void makeCall() {
try {
// Create SOAP Connection
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection soapConnection = soapConnectionFactory.createConnection();
// Send SOAP Message to SOAP Server
String url = "http://ws.cdyne.com/emailverify/Emailvernotestemail.asmx";
SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url);
// Process the SOAP Response
printSOAPResponse(soapResponse);
soapConnection.close();
} catch (Exception e) {
System.err.println("Error occurred while sending SOAP Request to Server");
e.printStackTrace();
}
}
private static SOAPMessage createSOAPRequest() throws Exception {
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage soapMessage = messageFactory.createMessage();
SOAPPart soapPart = soapMessage.getSOAPPart();
String serverURI = "http://ws.cdyne.com/";
// SOAP Envelope
SOAPEnvelope envelope = soapPart.getEnvelope();
envelope.addNamespaceDeclaration("example", serverURI);
// SOAP Body
SOAPBody soapBody = envelope.getBody();
SOAPElement soapBodyElem = soapBody.addChildElement("VerifyEmail", "example");
SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("email", "example");
soapBodyElem1.addTextNode("mutantninja#gmail.com");
SOAPElement soapBodyElem2 = soapBodyElem.addChildElement("LicenseKey", "example");
soapBodyElem2.addTextNode("123");
MimeHeaders headers = soapMessage.getMimeHeaders();
headers.addHeader("SOAPAction", serverURI + "VerifyEmail");
soapMessage.saveChanges();
/* Print the request message */
System.out.print("Request SOAP Message = ");
soapMessage.writeTo(System.out);
System.out.println();
return soapMessage;
}
/**
* Method used to print the SOAP Response
*/
private static void printSOAPResponse(SOAPMessage soapResponse) throws Exception {
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
Source sourceContent = soapResponse.getSOAPPart().getContent();
System.out.print("\nResponse SOAP Message = ");
StreamResult result = new StreamResult(System.out);
transformer.transform(sourceContent, result);
}}
When a call this SOAP service in my rest object and run piece of memory detector ;
public void restService(){
SOAPClientSAAJ test= new SOAPClientSAAJ();
test.makeCall();
Runtime runtime = Runtime.getRuntime();
runtime.gc();
long memory = runtime.totalMemory() - runtime.freeMemory();
System.out.println("Used memory is bytes: " + memory);
}
It shows each call consume 1 MB memory and at the end the Rest application crush. I debug it many times and saw that SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url); this part highly is the cause of the leak but I couldn't find a solution. Any help about that would be great.

i'm making a webservice client with SAAJ java.
I'n the client i ask info of the webservice. But the webservice is protected with a username and password.
And i don't no how i must add these 2.
I tried it in my code ( see commands ) but no results ..
// SAAJ - SOAP Client Testing

}
private static SOAPMessage createSOAPRequest(String soapAction) throws Exception {
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage soapMessage = messageFactory.createMessage();
createSoapEnvelope(soapMessage);
MimeHeaders headers = soapMessage.getMimeHeaders();
headers.addHeader("SOAPAction", soapAction);
soapMessage.saveChanges();
/* Print the request message, just for debugging purposes */

}
From what I understand, you have to add it to the header.
In your code for CreateSoapRequest you need 3 additional lines.
MimeHeaders headers = soapMessage.getMimeHeaders();
String encoded = new sun.misc.BASE64Encoder().encode((username+":"+password).getBytes());
String authString = "Basic " + encoded;
headers.addHeader("Authorization", authString);
headers.addHeader("SOAPAction", soapAction);
I think it matters what type of encoding the site has. So this probably won't work in a cut and paste you have to figure out what it requires.
The code below is what I have been using to understand the concept of soap messages etc. However, in this code there are 2 lines which state-
MimeHeaders headers = soapMessage.getMimeHeaders();
headers.addHeader("SOAPAction", serverURI + "VerifyEmail");
Why is this not viewable when printed? Also I would like to add the header "<?xml version="1.0" encoding="utf-8"?>" How can this be done? and how can I get the entire output/view of what it looks like sent. Header and everything? Thank You.

I'm not certain whether or not there is a way to print them directly from DOM or SOAP, but you can parse out the values and print them separately:
SOAPHeader header = message.getSOAPHeader();
if (header == null) {
// Throw an exception
}
NodeList headerPartNode = header.getChildNodes();
String headerPart = headerPartNode.item(0).getChildNodes().item(0).getNodeValue();
You can iterate over that NodeList, parse out each header part, and then print them individually for example.
I need to send following soap request on server:
<CallengeState xmlns="http://app.test.com/ws/schema">
<number>0008</number>
<previousState>Stopped</previousState>
<currentState>Activated</currentState>
<dateChanged>2014-06-09</dateChanged>
</CallengeState >
I know how to do it via Soap Ui, but I need to do this via java. In Soap UI I also specify additional parameter, here is screenshot:
I have found in google and tried following:
package com.oberthur.tests.util;
import javax.xml.soap.*;

// Process the SOAP Response
printSOAPResponse(soapResponse);
soapConnection.close();
} catch (Exception e) {
System.err.println("Error occurred while sending SOAP Request to Server");
e.printStackTrace();
}
}
private static SOAPMessage createSOAPRequest() throws Exception {

soapBodyElem4.addTextNode("2014-06-09");
soapMessage.saveChanges();
/* Print the request message */
System.out.print("Request SOAP Message = ");
soapMessage.writeTo(System.out);
System.out.println();
return soapMessage;

System.out.print("\nResponse SOAP Message = ");
StreamResult result = new StreamResult(System.out);
transformer.transform(sourceContent, result);
}
}
But I don't know how to set in this code my parameter and I got following error:
Response SOAP Message = [Fatal Error] :2:6: The processing instruction target matching "[xX][mM][lL]" is not allowed.
Error occurred while sending SOAP Request to Server
I want to call RFC function in SAP, I already could make request from Java and get the WSDL response. But I want to send a parameter with the SOAP request ? How to do that ?
The class below, I used it to create the request and get response :

SOAPConnection soapConnection = soapConnectionFactory.createConnection();

SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url);
// print SOAP Response
System.out.print("Response SOAP Message:");
soapResponse.writeTo(System.out);
soapConnection.close();
}
private static SOAPMessage createSOAPRequest() throws Exception {
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage soapMessage = messageFactory.createMessage();
SOAPPart soapPart = soapMessage.getSOAPPart();
String serverURI = "http://ws.cdyne.com/";
// SOAP Envelope
SOAPEnvelope envelope = soapPart.getEnvelope();
envelope.addNamespaceDeclaration("example", serverURI);
// SOAP Body
SOAPBody soapBody = envelope.getBody();
SOAPElement soapBodyElem = soapBody.addChildElement("pernr","example");
soapBodyElem.addTextNode("10001001");
String authorization = new String(Base64.encodeBase64(("hr_develop:unrwa2013").getBytes()));
soapMessage.getMimeHeaders().addHeader("Authorization","Basic " + authorization);
soapMessage.saveChanges();
/* Print the request message */
soapMessage.writeTo(System.out);
System.out.println();
return soapMessage;
}
}
I am provided with the following example request, but I don't know how to actually execute it.

I have tried to write a Java client...

However, I get a connection time-out. Also, the output SOAP message has an envelope that does'nt completely match the envelope of the example request.

Is something wrong with the client? Or is it the service provider?
Can you try this in your code:
SOAPElement getBusStopsList = soapBody.addChildElement("GetBusStopsList", "", "http://miz.it/infotransit");
EDIT: The first letter is lower case in getBusStopsList. So, please try GetBusStopsList.
Here is new code:
SOAPElement GetBusStopsList = soapBody.addChildElement("GetBusStopsList", "", "http://miz.it/infotransit");
