Body
I am currently developing a RESTful Webservice in Java using the Jersey library. For security reasons, we want a custom authentication similar to Amazons Simple Storage Service. This requires, however, that I calculate an MD5 hash of the body (if there is any) to authenticate the request. So far, I have used a custom Authenticator and Realm and plugged them into my context. Upon trying to calculate the hash I first used the request itself resulting in an IllegalStateException, since the body can only be read once. After investigating the problem I tried to wrap the request inside a HttpServletRequestWrapper but hasn't been successful so far. I am basically using a wrapper like the one shown here: <a href="http://forums.oracle.com/forums/thread.jspa?threadID=2156814&tstart=0" rel="nofollow">http://forums.oracle.com/forums/thread.jspa?threadID=2156814&tstart=0</a> Inside my realm, where I do the authentication, I am first creating the wrapper like so: <pre><code>MyRequestWrapper requestWrapper = new MyRequestWrapper(request); </code></pre> then I am calculating the MD5 using the requestWrapper and finally forwarding it <pre><code>request.getRequestDispatcher("/*").forward(requestWrapper, response); </code></pre> The processing works fine but I get an error like this after that: <pre><code>Servlet.service() for servlet Jersey REST Service threw exception java.lang.IllegalStateException at org.apache.catalina.connector.ResponseFacade.sendError(ResponseFacade.java:407) at com.sun.jersey.spi.container.servlet.WebComponent$Writer.finish(WebComponent.java:285) at com.sun.jersey.spi.container.ContainerResponse.write(ContainerResponse.java:241) </code></pre> Note that there is no mentioning of the getReader or getInputStream being called before (like I got without using any wrapper at all). Now I am sure I am doing something wrong here but I really don't know much about this and would be really glad if someone could help me out here :) Best Regards, Lukas

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.
