Hi All

1 written a service interface
2 written impl class which is as below
3 compiled and created ear file using config.xml file
4 started the oc4j server
5 deployed the generated ear file into the server
6 binded the service
7 Checked if the service is running by the following url
http://yourhost.com:8888/docws/validate
it is sucessful
8 prepared a jsp client
9 placed it in default-wep-app directory
10 opened the browser and called the jsp
it has displayed me with a html form where i have to give some input.
when clicked on submit
i did not call the service
so when i look at the server console
it says as follows
java.lang.IllegalArgumentException: Root element of a SOAP message must be: 'http://schemas.xmlsoap.org/soap/envelope/:Envelope'.

Hi Ramadhar,
If you are accessing the Webservice through the proxy you need to configure the proxy.
1. Follow the menu Path:
<b></b>System Administration>System Configuration>Service Configuration>Applications>com.sap.portal.ivs.httpservice>Services>proxy<i></i> and edit the property fields "HTTP-Enable Proxy Setting", "HTTP Proxy Host", and "HTTP Proxy port" and save.
2.Right click on "com.sap.portal.ivs.httpservice" node and choose "Administrate" and restart the service.
Hope this helps.
