What is SOAP?
SOAP is the Simple Object Access Protocol. It is used for information exchange and RPC, usually (but not necessarily) over HTTP. More information can be found at:
Developmentor SOAP FAQ: http://www.soaprpc.com/faqs/SoapFAQ.html
W3C specifications: http://www.w3.org/TR/SOAP/
What is WSDL?
WSDL is the Web Service Description Language. It provides a formal description of a web service, much like CORBA's IDL. The WSDL file is all you need to know how to call the web service; toolkits can generate proxy code from a WSDL file directly. The official WSDL definition is at http://www.w3.org/TR/wsdl.

Lab Google Search Web Service
"nothing builds self-esteem and self-confidence like accomplishment"
Explore Google search web service.
Developers write software programs that connect remotely to the Google Web APIs service. Communication is performed via the Simple Object Access Protocol (SOAP), an XML-based mechanism for exchanging typed information.
If you have questions, you can check into FAQ.
1. Take a close look at Web Service Description Language (WSDL 1.1) description of interface for Google searching
2. Download the web service API of Google search at http://www.google.com/apis/download.html
The download package includes
com.google.soap.search.*;
Google's own Java wrapper for the API SOAP calls
JAF 1.0.1 (activation.jar)
3. You need to create an account at Google to use the web service. Be sure to have an email box to receive the license key.
If you don't, just use this one nQ4ETIdQFHKlGxLZjj+2c8klYflwDzoK
4. Open the DOS command window and prepare to run Java.
Usage:
java -cp googleapi.jar com.google.soap.search.GoogleAPIDemo [key] search Foo
Where[key] is your registration key and Foo is the item you wish to
search for.
5. Take a close look at the XML output, which is the result of your search.

1. Take a look at the schema of Zip Code Web Service.
2. Use the lincense key eUhOTOJs9D2mcHU6SiL0CyMQvpJ3I3PqR2/fpRq4BOApWxzSzw7wD2FQ2mOmHEk+pq6iRBomQ4wuQl5EGOgfCitYgkQ3N4vl
to use this web service or subsbcribe to it at Zip codes lookup To apply for the license key by yourselves, be sure to have an email box to receive it.
2. Click GetPlacesInside and play with this operation
3. Enter 61801 as zip code and see what you get in the result.
4. Try again 92345 as zip code. Based on
the method of Lab XSLT,
write an XSLT and transform the result XML into an HTML.

- HTML for machine-human interaction
- XML can be formatted to HTML according to formartting rules called XSLT. To see it, do Lab XSLT.
- XML for machine-machine interaction
- Without human involvement, automation of business systems can be accelerated.
