writing to a http server using java

[ramki siva]

Hi friends,

This being my first post i apologize if i had broken any of the norms during this post.Please correct if there is anything so that they won't be repeated.

Now to the question,

I have a Wepsphere app server from where i am trying to write a text file to an apache http server using java HTTPConnection class.

I receive the following error when trying to do so ...
"Server returned HTTP response code: 405 for URL ******************* " which i understand is URL forbidden error.

My question is:
1.Is it possible to write directly to a http server from app server.{i was using http PUT}
2. If so , can you please throw some light on what configuration changes on http server should i make for it to work.
3.Is there a better way of doing the same without using HTTPConnection class

Thanks in Advance

1. Yes.

2. You shouldn't have to make any changes to the HTTP server. You should change your code so that it sends data in the format required by the HTTP server.

3. You don't have to use Apache's HTTPConnection class. However whether the alternatives are "better" depends on what you mean by that.

Hi Paul,

Thanks for the reply.

I have tried the following piece of code without any luck.

String urlString="http://<hostname>/<path>/file.txt";
			url = new URL(urlString);
    		HttpURLConnection connection=(HttpURLConnection)url.openConnection();
    		if(connection!=null){
    			System.out.println("Established URL connection");
    	    }
    		connection.setDoOutput(true);    		
    		connection.setRequestMethod("PUT");
    		connection.setDoInput(true);
    		connection.setUseCaches(false);
    		connection.setRequestProperty ("Content-Type", "text/html");
    		OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
    	   writer.write("This is a sample text");
    	   writer.close();

When i try this i get a http response code 302.and i don't see any data being written to the file

Is the above code,the standard/correct way of using HTTP PUT?Anything else that needs to be considered for this to work?

You'll need to consider whether the server actually wants a PUT request. Since the error message you got strongly suggested that it rejected the PUT request, perhaps you ought to ask what type of request it wants. There's no point in spending time to get your PUT request exactly right if PUT isn't the right type to use.

"perhaps you ought to ask what type of request it wants."

How do i find that... Is there any particular entry in http server's httpd.conf files that i should be aware of?

[Paul Clapham]

How do you find that? You ask the person who wanted you to upload that file.

If you are thinking that you can do a PUT to any random server and have it accept the request, well, that's not going to happen.

Why don't you tell use what's at the URL you are trying to send the PUT to?
