Hey, I'm trying to get the html from a twitter profile page, but httpurlconnection is only returning a small snippet of the html.

I do not have as good of an understanding of HTTP as I would like to. Any insight will be greatly appreciated! I needed to upload a JSON that contained information about an object. This object could have image, audio, and video files associated with it. These data files had to be uploaded, after the JSON, as part of a multipart reque...
I am trying to write a java program that will automatically download and name some of my favorite web comics. Since I will be requesting multiple objects from the same domain, I wanted to have a persistent http connection that I could keep open until all the comics have been downloaded. Below is my work-in-progress. How do I make another...
I know this issue should be fixed with System.setProperty("http.keepAlive", "false"); before openConnection, but that didn't work to me. First try on this code works, second one fails. Even if i try this request after less than 5 seconds, it also works. If i wait more than that, it fails again This is my code: System.setProperty("h...

I have read that HttpURLConnection supports persistent connections, so that a connection can be reused for multiple requests. I tried it and the only way to send a second POST was by calling openConnection for a second time. Otherwise I got a IllegalStateException("Already connected"); I used the following: try{ URL url = new URL("http:...

I have a piece of Java code that opens a HTTP connection, writes data on that and then retrieves the response code. Since, the connectin was fine it should get HTTP_OK (i.e 200) but it is getting 1 in return. This is baffling as 1 appears nowhere in the Http Response code specification. Could anyone throw some ideas on the potential pro...
Hi, I'm a problem with a HttpsURLConnection that I can't seem to solve. Basically, I'm sending up some info to a server and if some of that data is wrong, the server sends me a 500 response code. However, it also sends a message in the response telling me which bit of data was wrong. The problem is that the message is always empty when I...

Hello, we are upgrading our web app to use Facebook's Graph API, which returns JSON responses. However we don't want to add dependecy to a JSON library unless we have no other choice. For server-side http requests we use Apache HttpComponents. Thus, my question is what are the classes (if any) in the JDK and/or in HttpComponents that I...
Hi all, I'm trying to use an HttpURLConnection in my application. I set my request method to 'GET', but when I try to retrieve the output stream then the method is changed to 'POST' ! I'm not sure that is the reason, but my JSON server (I use JAX-RS) returns a blank page when I send a request using a 'POST'. Here is a snippet of my cod...
