Before you can use an Iguana channel to send data to a web service, you must first download the SOAP.py library from the iNTERFACEWARE FTP site and then install it. The Python script that accesses the web site (which is described in Creating a VMD File To Call the Web Service) uses methods defined in the SOAP.py library to communicate with the web service.

To download and install the SOAP.py library:

• In your web browser, go to the following URL: http://dl.interfaceware.com/oss/SOAPpy/.
• Click the SOAPpy-ifw-0.11.4.zip link. This will download a copy of a version of the SOAP.py library that has been modified to work in the Iguana environment.
• Using the system's extract program, unpack the SOAPpy-ifw-0.11.4.zip file. (To do this in the Windows environment, right-click the file name and select Extract All.)
• Move the extracted SOAPpy-ifw-0.11.4 folder to your preferred location on the system (such as C:\MySOAPDirectory). Remember this location, as you will need to supply it in a Python script.
• In the http://dl.interfaceware.com/oss/SOAPpy/ directory, click the fpconst-0.7.2.zip link to download a copy of fpconst. You will need this Python library to use SOAP.py in the Iguana environment. You can put this file in any temporary location on your system.
• Using the system's extract program, unpack fpconst-0.7.2.zip. From the fpconst-0.7.2 directory that is created, copy fpconst.py to the lib subdirectory of the directory in which you have installed Chameleon.

When the SOAPpy library is installed, the next step is to create the VMD file that extracts data from the incoming HL7 messages.
