    <p>Is there a way to create a very basic HTTP server (supporting only GET/POST) in Java using just the Java SE API, without writing code to manually parse HTTP requests and manually format HTTP responses? The Java SE API nicely encapsulates the HTTP client functionality in HttpURLConnection, but is there an analog for HTTP server functionality?</p> <p>Just to be clear, the problem I have with a lot of ServerSocket examples I've seen online is that they do their own request parsing/response formatting and error handling, which is tedious, error-prone, and not likely to be comprehensive, and I'm trying to avoid it for those reasons.</p> <p>As an example of the manual HTTP manipulation that I'm trying to avoid:</p> <p><a href="http://java.sun.com/developer/technicalArticles/Networking/Webserver/WebServercode.html" rel="noreferrer">http://java.sun.com/developer/technicalArticles/Networking/Webserver/WebServercode.html</a></p>

    1. COUmm...the short answer is no. If you want something that handles post and get requests without manually writing the http headers then you could use servlets. But thats java ee. If you don't want to use something like that then sockets and manual parsing is the only other option I know of.

    2. COI know this isn't in the spirit of SO, but I would urge you to reconsider you distaste for Java EE API's. As some of the answers have mentioned, there are some very straight-forward implementations such as Jetty that allow you to embed a web server in your stand-alone application while still taking advantage of the servlet api. If you absolutely can't use the Java EE API for some reason than please disregard my comment :-)

    3. CO"Servlets" are not really "Java EE". They are just a way of writing plugins that can be called by the surrounding application in response to message activity (these days, generally HTTP requests). Providing a servlet hosting environment "using just the Java SE API" is exactly what Jetty and Tomcat do. Of course you may want to *throw out unwanted complexity* but then you may need to decide on a subset of the allowed attributes and configurations of the GET/POST. It's often not worth it though, except for special security/embedded problems.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
