How to get MetaData from web service

[Mittal Vishal]

Hi,

I am new in web service

Can you please tell me how to get the metadata from web service e.g. operation Names, parameters, schema information

Thanks

Talk to the provider about how to get the WSDL (or WADL, if it's a REST service). It has all the information you need to build client code.

Thanks Tim,

My application is a core Java application
It takes URL of web service as input
I have used WSDL jar to parse it .

I am able to get the operation names from the service
But I need to know the schema information of the service

so that I can parse the response based on the schema
Please suggest

Thanks

The WSDL contains information about all data types needed to use the WS, so what do you mean by "schema information"?

Hi Tim,

I know that WSDL provides all the information but...

For e.g. In the following web services

http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL

I have to map GetWeatherInformationResponse to ArrayOfWeatherDescription which is again mapped to WeatherDescription which actually have the output elements

I can write my own logic which can map them, all I want to know is, is there any in build logic which can provide me a mapping which maps GetWeatherInformationResponse to WeatherDescription or to its child

Thanks

All major SOAP stacks have tools (maybe called something like wsdl2java) that can generate Java code -including all the data classes- from a WSDL.
