Generate HTTP PUT request

[Arpit Purohit]

I want to generate HTTP PUT request programatically using java.
Can anybody help on this topic.

[Peter Chase]

Try Jakarta HttpClient. It's free.

Welcome to JavaRanch.

Something like the following will do the trick:

URL url = new URL("http://...");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setRequestMethod("PUT");

[Peter Chase]

Yes, it depends how advanced your usage will be. Plain JDK Java will do for the simplest cases, but Jakarta HTTPClient will help a lot with more-difficult cases.

let's slide this over to the Servlets forum, not sure that's the best place but it's better than here

Hi friends,
let me make it more clear about HTTP PUT request.
It is used to create new resource on server.And same i want to do programatically.
Can anybody give me example for that?

[Ulf Dittmer]

Can you be more specific what you're trying to do? Peter and myself mentioned two possibilities how to send a request from the client side; on the server side you can use a servlet's doPut method. If that doesn't help, tell us where you're stuck implementing this, and we'll try to get you going again.

Not really a servlets question either (unless you need help with the doPut methdod). Moving to Sockets and Internet Protocols.

Being more specific,
I want to create a resource on server by sending PUT request from the client (which is the basic usage PUT request ). I know very well that PUT request is handled on server side (servlet) using doPut() method. But i am not clear about following things:

1. How can i generate PUT request from client (say java program)?
2. Further, how and what to handle on servet's doPut() method so as to create
resource?
3. As known, PUT request is to create resource on server, do i have to provide
resource name(to be created) as parameter in the request and how?

Paul and I mentioned two ways of doing this. What else are you looking for?

2. Further, how and what to handle on servet's doPut() method so as to create resource?

3. As known, PUT request is to create resource on server, do i have to provide resource name(to be created) as parameter in the request and how?

Conceptually, a PUT is somewhat similar to a POST, with the body of the request containing the resource. So you'd use the Request.getInputStream method to get at the data of the resource.

The name of the resource is the URI (or URL in this case), so no extra name is supplied. You should read section 9.6 of the HTTP specification (and the other sections it points to) for further details regarding the implementation.
