This code could be used in any type of application (Windows, console ...). Here, RemoteGlobalCurrencies is the web reference to the web service. Note that the default name for a web reference is generally "com.xignite.www". You will need to rename your web reference to use to use this code.

// add authentication info
RemoteGlobalCurrencies.Header objHeader = new RemoteGlobalCurrencies.Header();

Java/Axis

This section assumes that you have Axis installed on your machine and that you are fairly familiar with it.

Because all our web services return complex types, the best way to use Axis (Apache Axis2 1.4+) is to first generate a proxy class using the 'WSDL2Java' tool'. By default, the tool will put all generated classes into the package "com.xignite.www.services".

You should then compile the classes (including the axis dependencies):


C:\axis>java org.apache.axis.wsdl.WSDL2Java http://globalcurrencies.xignite.com/xGlobalCurrencies.asmx?WSDL
C:\axis>javac com\xignite\*.java
C:\axis>
C:\axis>YOUR_AXIS_INSTALLATION\bin\wsdl2java.bat -ap -uri http://globalcurrencies.xignite.com/xGlobalCurrencies.asmx?WSDL
C:\axis>javac -classpath "YOUR_AXIS_INSTALLATION/lib/*" com/xignite/www/services/*.java

You can then create your source file. See below


After creating your source file, you can compile it like this:

C:\axis>javac -classpath .;"YOUR_AXIS_INSTALLATION/lib/*" XigniteGlobalCurrenciesDemo.java

// By default, all of the classes auto-generated by the Axis2 
// "WSDL2Java" tool are placed into the package "com.xignite.www.services"
// for our Xignite WSDL, so we need an import.
import com.xignite.www.services.XigniteGlobalCurrenciesXigniteGlobalCurrenciesSoapStub; import com.xignite.www.services.XigniteGlobalCurrenciesXigniteGlobalCurrenciesSoapStub.*;
public class XigniteGlobalCurrenciesDemo {
public static void main(String[] args) throws Exception { // Instantiate the XigniteGlobalCurrencies proxy
// proxy object using the Helper class.
// This class was autogenerated by the WSDL2Java tool

try { XigniteGlobalCurrenciesXigniteGlobalCurrenciesSoapStub stub = new XigniteGlobalCurrenciesXigniteGlobalCurrenciesSoapStub(); // Instantiate the return class from the operation
// This class was autogenerated by the WSDL2Java tool
ConvertHistoricalValue convertHistoricalValueArguments = new ConvertHistoricalValue(); convertHistoricalValueArguments.setFrom("EUR");
convertHistoricalValueArguments.setTo("USD");
convertHistoricalValueArguments.setAmount(1500);
convertHistoricalValueArguments.setAsOfDate("5/22/2015");
convertHistoricalValueArguments.setFixingTime("22:00");
// Add authentication info
HeaderE header = new HeaderE(); Header myHeader = new Header(); myHeader.setUsername("YOUR_TOKEN"); header.setHeader(myHeader);

ConvertHistoricalValueResponse response = stub.convertHistoricalValue(convertHistoricalValueArguments, header); RateConversion objRateConversion = response.getConvertHistoricalValueResult(); // objRateConversion is pointing to the result of the operation
if (objRateConversion.getOutcome() == OutcomeTypes.RegistrationError) { // code to handle registration errors
System.out.println(OutcomeTypes.RegistrationError.toString() + ": " + objRateConversion.getMessage()); } else if (objRateConversion.getOutcome() == OutcomeTypes.RequestError) { // code to handle request errors
System.out.println(OutcomeTypes.RequestError.toString() + ": " + objRateConversion.getMessage()); } else if (objRateConversion.getOutcome() == OutcomeTypes.SystemError) { // code to handle system errors
System.out.println(OutcomeTypes.SystemError.toString() + ": " + objRateConversion.getMessage()); } else // Success
{ System.out.println(objRateConversion.getSource()); } } catch (Exception ex) { // add exception handling code here

} } }

Perl/SoapLite

This section assumes that you have SOAP::Lite for Perl installed on your machine and that you are fairly familiar with it. But just in case your are not:

You can then use a text editor to create the source code below. You can execute it by running:


C:\perl\perl demo.pl

Note that there are some unique steps to follow to use SOAP::Lite with .Net web Services. For detailed info, check this article on MSDN.

Here is a sample source for this operation.
# the maptype instruction is critical for compatibility 
use SOAP::Lite maptype => {};
use Data::Dumper;

# this is our namespace
my $namespace = 'http://www.xignite.com/services/';

# declare the service using the namespace, the SOAP action and the uri
my $service = SOAP::Lite
-> uri($namespace)
-> on_action( sub { join '/', 'http://www.xignite.com/services', $_[1] } )
-> proxy('http://globalcurrencies.xignite.com/xGlobalCurrencies.asmx');

# .Net requires the method, header, and attributes to be fully qualified
my $method = SOAP::Data->name('ConvertHistoricalValue')
->attr({xmlns => $namespace});

# this section is required for authentication
# you can skip it if you use IP-based authentication
my $header = SOAP::Header->name(Header => {
Username => '<your username here>'})->uri($namespace)->prefix('');

# same here, you can omit $header if you use IP-based authentication

my @params = ( $header,
SOAP::Data->name(From => "EUR")->uri($namespace),
SOAP::Data->name(To => "USD")->uri($namespace),
SOAP::Data->name(Amount => "1500")->uri($namespace),
SOAP::Data->name(AsOfDate => "5/22/2015")->uri($namespace),
SOAP::Data->name(FixingTime => "22:00")->uri($namespace));
# you can now call the service
my $result = $service->call($method => @params);
if ($result->fault)
{
print $result->faultstring;
}
else
{
# here we parse the output using the main return class
# and one of its attributes
# Uncoment the line below to print the full result object graph:
# print Dumper($result);
print $result->valueof('//ConvertHistoricalValueResult/objRateConversion/Source'), "\n";
}

PHP/NuSoap

NuSoap is one of the three major SOAP implementations for PHP: PEAR::SOAP, NuSOAP, and PHP-SOAP.

If you use PHP, we recommend you use NuSoap to access our web services. NuSoap uses our web services for demonstration in their own documentation and it works well.

This section assumes that you have PHP installed on your machine and that you are fairly familiar with it. We have tested this implementation for PHP 4.2.1 on Windows 2000. It should also work with more recent versions on more recent platforms. Note that PHP 5.0 supports SOAP natively (without extension), please follow their documentation for upgrade or code changes required.

To install NuSoap, download the latest package from this location. You can unzip the package in your PHP application directory. The package includes libraries (/lib) and samples (/samples). The sample code below is based on the wsdlclient1.php sample.

If you use one of the older version or PHP (i.e. 4.2.1) , you will need to comment out one line in the /lib/nusoap.php file. That section is not supported in earlier version. The line to comment out is line 1877 as shown below.


1876 // set response timeout
1877 //socket_set_timeout( $this->fp, $response_timeout);

You can then create your source file.


<?php
// need to use the NuSoap extension
require_once('../lib/nusoap.php');

// if you access the internet through a proxy server
$proxyhost = isset($_POST['proxyhost']) ? $_POST['proxyhost'] : '';
$proxyport = isset($_POST['proxyport']) ? $_POST['proxyport'] : '';
$proxyusername = isset($_POST['proxyusername']) ? $_POST['proxyusername'] : '';
$proxypassword = isset($_POST['proxypassword']) ? $_POST['proxypassword'] : '';

// define the SOAP client using the url for the service
$client = new soapclient('http://globalcurrencies.xignite.com/xGlobalCurrencies.asmx?WSDL',
true, $proxyhost, $proxyport, $proxyusername, $proxypassword);

// assess the results
$err = $client->getError();
if ($err) {
echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
}

// create an array of parameters
$param = array(
"From" => "EUR",
"To" => "USD",
"Amount" => "1500",
"AsOfDate" => "5/22/2015",
"FixingTime" => "22:00");
// call the service, passing the parameters and the name of the operation
$result = $client->call('ConvertHistoricalValue', array('parameters' => $param), '', '', false, true);
// assess the results
if ($client->fault) {
echo '<h2>Fault</h2><pre>';
print_r($result);
echo '</pre>';
} else {
$err = $client->getError();
if ($err) {
echo '<h2>Error</h2><pre>' . $err . '</pre>';
} else {
// display the results
echo '<h2>Result</h2><pre>';
// this function exposes the complete structure of the return class
print_r($result);
echo '</pre>';
}
}
// print the SOAP request
echo '<h2>Request</h2><pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';
// print the SOAP response
echo '<h2>Response</h2><pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre>';
// print the PHP debugging trace
echo '<h2>Debug</h2><pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre>';
?>

PHP 5

PHP-SOAP is one of the three major SOAP implementations for PHP: PEAR::SOAP, NuSOAP, and PHP-SOAP.

This section assumes that you have PHP5.0 installed on your machine and that you are fairly familiar with it.

Note that PHP 5.0 supports SOAP, please follow their documentation for code changes required.

Here is a sample source for this operation.

<?php
// define the SOAP client using the url for the service
$client = new soapclient('http://globalcurrencies.xignite.com/xGlobalCurrencies.asmx?WSDL');
// create an array of parameters
$param = array( "From" => "EUR",
"To" => "USD",
"Amount" => "1500",
"AsOfDate" => "5/22/2015",
"FixingTime" => "22:00");
// add authentication info
$xignite_header = new SoapHeader('http://www.xignite.com/services/',
"Header", array("Username" => "YOUR_TOKEN"));
$client->__setSoapHeaders(array($xignite_header));

// call the service, passing the parameters and the name of the operation
$result = $client->ConvertHistoricalValue($param); // assess the results
if (is_soap_fault($result)) { echo '<h2>Fault</h2><pre>'; print_r($result); echo '</pre>'; } else { echo '<h2>Result</h2><pre>'; print_r($result); echo '</pre>'; } // print the SOAP request
echo '<h2>Request</h2><pre>' . htmlspecialchars($client->__getLastRequest(), ENT_QUOTES) . '</pre>'; // print the SOAP request Headers
echo '<h2>Request Headers</h2><pre>' . htmlspecialchars($client->__getLastRequestHeaders(), ENT_QUOTES) . '</pre>'; // print the SOAP response
echo '<h2>Response</h2><pre>' . htmlspecialchars($client->__getLastResponse(), ENT_QUOTES) . '</pre>'; ?>

soap_header = { "Header" => { "@xmlns" => "http://www.xignite.com/services/", "Username" => "YOUR_TOKEN" } }
client = Savon.client(wsdl: url, :soap_header => soap_header, convert_request_keys_to: :none, env_namespace: 'soap')
response = client.call(:convert_historical_value, message: {
"@xmlns" => "http://www.xignite.com/services/",

XSLT

When working with XSL, you only need to worry about properly dealing with namespaces.

The general principle in working with XSL is to apply the stylesheet (the XSL document) to the output of the web service (XML document). The code required to accomplish this varies based on your envirobment. For instance, using VB.Net it would be:

Dim objSOAPClient
Dim objTemplate As New System.Xml.Xsl.XslTransform()
objTemplate.Load(<url_of_XSL_template>)
objTemplate.Transform(<url_of_input_document>,<url_of_output_document>)

In the code above, you want to replace the <url_of_input_document> with the following URL.

http://globalcurrencies.xignite.com/xGlobalCurrencies.asmx/ConvertHistoricalValue?From=EUR&To=USD&Amount=1500&AsOfDate=5/22/2015&FixingTime=22:00


And this is how you could write the XSL stylesheet. Note that all node names are prefixed.

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xi="http://www.xignite.com/services/"
version="1.0" exclude-result-prefixes="xi">
<xsl:template match="xi:RateConversion">
<p>
<xsl:value-of select="xi:Source"/>
</p>
</xsl:template>
</xsl:template></xsl:stylesheet>
