node 1.1 development resources
Links to the Node 1.1 Functional Specification and Exchange Protocol are available in the table below along with some additional guidance materials.
* Note that this document should be used only for background reference, as much of the information has been superseded by other guidance.
node 1.1 node configurations
Many Exchange Network partners have developed and successfully deployed several Node and client configurations. A number of these Demonstrated Node Configurations (DNCs) are freely available for download on this page. All Node builders are strongly encouraged to take advantage of these DNCs because they are proven solutions that will help you further your progress and cost savings.
The available DNCs are categorized by the environment in which they were deployed. The executable files will allow Node builders with similar platforms to quickly deploy their Nodes and save significant costs. The accompanying documentation describes the implementation process.
These DNCs are compatible with v1.1 Node Specification and Protocol.
Java-based Apache Axis 1.1
Can be used with BEA Weblogic, IBM Websphere, Oracle, XAware, Microsoft .NET web server products. This package includes both server (serving up pages/data) and client (generate request) configurations. Requires JDK 1.3.X (Includes Axis 1.1 requestor which is free from Sun Java Developers Kit).

Microsoft .NET
- Microsoft .NET Node by Windsor Solutions
Version 3.0 of the Node developed by Windsor Solutions is available for download from their website at http://www.nodecentral.com. The site includes downloads for the Node, plug-ins for several data exchanges, and reference documentation. Please note that technical support for deployment of the Node and configuration of any data flows is not necessarily included. Contact the vendor for more information about obtaining technical support for the product. Windsor's Node Central website allows for downloads of their full Node product while the link on our Network Clients page is for the Node Client application only.

- DNC for server side using Microsoft .NET VB
This requires .NET Framework 1.X and WSE 1sp1. DNC (executable files) for client side (to generate requests) for Microsoft .NET.

- Sample client for .NET
This is a sample client that uses the included requestor library (CDX_DOTNET_REQUESTOR.DLL). This library is all that is needed to communicate with a Node from any .NET language (e.g., VB, C#, J#). Only requires the .NET Framework 1.X and WSE 1sp1. Please note that the code is compiled so once you install you cannot make a lot of modifications.

- C# Client Library
This allows you to change the above requestor library. If you don't want to change the API, you should download the .NET Sample Client. Requires the .NET Framework 1.X and 1sp1.

other developer tools
- Node Test Site Version 1.1
This application provides the ability to test any Node in the Exchange Network, by triggering Network WSDL-compliant requests on that Node. If a Node passes a test with this tool, it is very likely to be interoperable with other Network WSDL-compliant Nodes. This tool, which is intended to verify general compliance with the Specification, focuses on interoperability among Nodes.
- Java Flow Processor
The Java Flow Processor was developed by CGI for the New Jersey Department of Environmental Protection. It is an extraction and transformation tool written in Java that is intended to simplify the deployment of Exchange Network data flows. For more information on the Flow Processor, you can download the accompanying User's Guide or contact William Labar at william.labar@cgi.com or 337.291.9854.
- Software Developer Kit (SDK)
The SDK is a COM object based tool to simplify Network interactions to a few lines of script code.
It sets up a node client then builds Network messages for you dynamically as it runs the script.
It has sample scripts for Network services.
It can execute any WSDL based service even Node 2.0 /Soap1.2 . (see
example)
- Click here to download the kit
- Unzip and double click the file to install the SDK.
It uses a standard install tool so just follow prompts
- It creates NodeClient2.0 directory containing:
- Example scripts in NodeClient2.0\Scripts directory
- Debug logs etc in NodeClient2.0\Logs directory
- execute example script (for calling any WSDL based services in this case a NAAS WSDL):
set myClient = CreateObject ("NodeClient") myClient.SetCredential "cdx", "test",""
'set our SSL certificate file
myClient.SetProperty "Certificate", "NodeClientSSL.pem"
'use local WSDL cache if any
myClient.SetProperty "WSDLAge", "23923932"
'Set the WSDL address you are calling
myClient.SetProperty "WSDLFile", "
https://naas.epacdxnode.net/xml/cdx_v10.wsdl"
'call the execute method to get the data rows = myClient.Execute("ClearTransaction","","")
