In this lesson, you call the wrapper procedure created in the previous lesson, which sends a request to the web server you created in lesson one. For more information about setting up a web client to send the requests described in this lesson, see Lesson 2: Setting up a web client to send RAW requests and receive RAW responses.
This lesson contains several references to localhost. Use the IP address of the web server from lesson 1 instead of localhost if you are not running the web client on the same computer as the web server.
Connect to the client database in Interactive SQL if it is not already open from lesson two.
dbisql -c "UID=DBA;PWD=sql;SERVER=echo_client"
Call the wrapper procedure to send the request and obtain the response.
Execute the following SQL statement in Interactive SQL:
CALL setMIME('<hello>this is xml</hello>', 'text/xml', 'http://localhost:8082/EchoService' );
The http://localhost:8082/EchoService variable indicates that the database server runs on localhost and listens on port 8082. The desired SOAP web service is named EchoService.
The following result set is displayed in Interactive SQL:
|Status||HTTP/1.1 200 OK|
|Body||<hello>this is xml</hello>|
|Date||Thu, 04 Feb 2010 13:37:23 GMT|
|Expires||Thu, 04 Feb 2010 13:37:23 GMT|
The following is representative of the HTTP packet that is sent to the web server:
POST /EchoService HTTP/1.0 Date: Thu, 04 Feb 2010 13:37:23 GMT Host: localhost Accept-Charset: windows-1252, UTF-8, * User-Agent: SQLAnywhere/22.214.171.1244 Content-Type: text/xml; charset=windows-1252 Content-Length: 49 ASA-Id: 1055532613:echo_client:echo:968000 Connection: close valueAsXML=<hello>this is xml</hello>
The following is the response from the web server:
HTTP/1.1 200 OK Server: SQLAnywhere/126.96.36.1994 Date: Thu, 04 Feb 2010 13:37:23 GMT Expires: Thu, 04 Feb 2010 13:37:23 GMT Content-Type: text/plain; charset=windows-1252 Connection: close <hello>this is xml</hello>
