Hi,

I am facing a sporadic (intermittent) issue when tried to send SOAP messages over HTTPS through a proxy. Below are the checks done

- SSL certificates installed.

- WebService end-point is always avaliable. No issue with it.

- When the failed messages are re-sent they go through fine.

- Connected through a proxy server.

- Using SAAJ api provided by Jboss installation

     /server/default/lib/saaj-api.jar

     /server/default/lib/saaj-impl.jar

- Java version: jdk1.5.0_11

- Jboss version: jboss-4.0.5.GA

Code Snippet of client which sends the SOAP message:

-----------------------------------------------------------------------------------

private String sendSoap(String content) throws IOException

    {

        String retValue = "";

        try {

            String methodName = this.properties.getProperty ("method");

            String url = this.properties.getProperty ("url");

            String soapAction = this.properties.getProperty ("action");

            if (soapAction==null) soapAction = "DEFAULT";

            String nameSpace = this.properties.getProperty (methodName+".namespace");

            String parameter = this.properties.getProperty (methodName+".parameter");

            javax.xml.soap.SOAPMessage message = javax.xml.soap.MessageFactory.newInstance().createMessage();

            message.getMimeHeaders().addHeader("SOAPAction",soapAction);

            javax.xml.soap.SOAPHeader header = message.getSOAPHeader();

            javax.xml.soap.SOAPBody body = message.getSOAPBody();

            javax.xml.soap.SOAPFactory soapFactory = javax.xml.soap.SOAPFactory.newInstance();

            javax.xml.soap.Name bodyName = soapFactory.createName(methodName,"ns0",nameSpace);

            javax.xml.soap.SOAPBodyElement bodyElement = body.addBodyElement(bodyName);

            javax.xml.soap.Name parameterName = soapFactory.createName (parameter);

            javax.xml.soap.SOAPElement parameterElement = soapFactory.createElement (parameterName);

            parameterElement.addTextNode (content);

            bodyElement.addChildElement (parameterElement);

            java.io.ByteArrayOutputStream out1 = new java.io.ByteArrayOutputStream();

            message.writeTo (out1);

            java.net.URL endpoint = new java.net.URL(url);

            javax.xml.soap.SOAPConnection conn = javax.xml.soap.SOAPConnectionFactory.newInstance().createConnection();

            javax.xml.soap.SOAPMessage response = conn.call(message,endpoint);

            java.io.ByteArrayOutputStream out2 = new java.io.ByteArrayOutputStream();

            response.writeTo(out2);

            logger.debug("XML Response String ==> " + out2.toString());

            javax.xml.soap.SOAPBody responseBody = response.getSOAPBody();

            org.w3c.dom.Document document = responseBody.extractContentAsDocument();

            retValue = document.getElementsByTagNameNS( nameSpace, methodName+"Return").item (0).getTextContent ();

       }

        catch (SOAPException ex)

        {       ex.printStackTrace();

            throw new IOException(ex.getMessage());

        }

        catch (FactoryConfigurationError ex)

        {

            ex.printStackTrace();

            throw new IOException(ex.getMessage());

        }

        return retValue;

    }
