    <p>I'm running some Scala code (with Java socialAuth library) that requires an HTTPServletRequest to be passed in as a param. </p> <pre><code>def myClass(prov: String, site: String, request: HttpServletRequest): { //some initial code here val session = request.getSession() session.setAttribute(/*some params*/) //code continues... } </code></pre> <p>So the HttpServletRequest seems like a really cool way of storing session variables and passing a session between methods. However, I'm not quite sure how to test this code, as I don't really understand what the HttpServletRequest interface <em>is</em>.</p> <p>I've done a bit of research, but I was wondering if anyone could clarify for me. <a href="http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpServletRequest.html" rel="nofollow">HttpServletRequest</a> is an interface, which means it can't be instantiated on its own. How, then is it used in code? </p> <p>EDIT: as in, when a method takes an HttpServletRequest as a parameter, what implementing class is usually passed in? </p> <hr> <p>FOLLOWUP: Based on the answers given, HttpServletRequest is implemented differently by different servers; Ireeder pointed out, for example, that Apache even has multiple implementations. How, then, does code specify that the server needs to use its implementation? In other words, lets say I have test code that uses myClass:</p> <pre><code>def otherClass(){ val site = "www.example.com" val provider = "twitter" val mockRequest = mock(HttpServletRequest.class) //using https://code.google.com/p/mockito/. (eclipse throws error..not too sure about syntax but throwing up this example quickly, so will edit later) myClass(provider, site, mockRequest) } </code></pre> <p>I assume this is OK for testing, as Mockito creates a mock object, but when otherClass() needs to be implemented on a server, how is its code adjusted? (Sorry, I'm a bit new at this, so bear with me...) If <code>val mockRequest</code> needs to be implemented with whatever HttpServletRequest implementation is used by the server (Apache, Oracle, etc), how does the user specify this in <code>otherClass</code>? Will something like this change:</p> <pre><code>//deleted line: --val mockRequest = mock(HttpServletRequest.class) //changed line: myClass(provider, site, mockRequest) to below: myClass(provider, site, javax.servlet.http.HttpServletRequest) </code></pre> <p>be interpreted and implemented correctly by the server?</p>

    1. COIt seems you are getting a little ahead of yourself if you are coding scala and don't know what an interface is. How does a trait work?

    2. CO... Classes implement interfaces. Interfaces specify a contract for the underlying implementation. Interfaces can't be instantiated, but classes *implementing* interfaces can. And no, tying code to the servlet spec isn't a really cool way of doing anything, because then you have to mock out stuff that's really only a thin layer between web clients and Code That Does Important Things.

    3. COI was wondering, more specifically, if either of you had experience with Java servlets and were familiar with what HttpServletRequest-implementing classes are most commonly used when testing programs that take an HttpServletRequest as a param

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.
