What is the difference between http: //aa.jsp? A = 1&b = 2 or a servlet and a webservice call?

Is there any better webservice than http call?

pzc061

webservice is a high-level protocol based on http, which is not comparable
Webservice is used for language-independent data transmission and method invocation. You should compare webservice and RMI


For a simple example, two services A\B, A need to call a method of B String getString (String param); directly call with webService, feels like a local call, but using http to implement it is very troublesome


There are many differences, you just need to search for it

Is http related to language? I post a.jsp and post a.asp and get a text string.
What is the relationship between the client program and jsp or asp writing this page program.

webservcie call directly?

httpost only needs new url, conn.read.

The webser requires many steps to start the call.

Finally figured it out.

The development tool can generate a local class interface based on the wsdl file.
Enter the wsdl file address, click a few buttons, and several types of local projects will appear.
These classes are just like using the interfaces of the classes on the remote server.

This is the biggest difference between webserivce and httppost for programmers.
