    <p>Your friend here is <a href="http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/web/context/request/RequestContextHolder.html" rel="noreferrer"><code>org.springframework.web.context.request.RequestContextHolder</code></a></p> <pre><code>// example usage public static HttpSession session() { ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes(); return attr.getRequest().getSession(true); // true == allow create } </code></pre> <p>This will be populated by the standard spring mvc dispatch servlet, but if you are using a different web framework you have add <code>org.springframework.web.filter.RequestContextFilter</code> as a filter in your <code>web.xml</code> to manage the holder.</p> <p><strong>EDIT</strong>: just as a side issue what are you actually trying to do, I'm not sure you should need access to the <code>HttpSession</code> in the <code>retieveUser</code> method of a <code>UserDetailsService</code>. Spring security will put the UserDetails object in the session for you any how. It can be retrieved by accessing the <code>SecurityContextHolder</code>:</p> <pre><code>public static UserDetails currentUserDetails(){ SecurityContext securityContext = SecurityContextHolder.getContext(); Authentication authentication = securityContext.getAuthentication(); if (authentication != null) { Object principal = authentication.getPrincipal(); return principal instanceof UserDetails ? (UserDetails) principal : null; } return null; } </code></pre>

    1. CO@first point: I tried using RequestContextHolder, it gave me an error: No thread-bound request found:Are you referring to ... use RequestContextListener or RequestContextFilter to expose the current request. I didnt try filters i guess, will try that and let u know if it works. @second point: actually its a custom object hence i didnt prefer UserDetails if possible do see my other question on similar topic: http://stackoverflow.com/questions/1629273/is-it-possible-to-send-more-data-in-form-based-authentication-in-spring

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
