Spring MVC: mvn sonar fails when mvn test passes

Stranger things have happened. But this blows many a mind. mvn test on a restful services project with spring mvc succeeds but mvn sonar:sonar fails with 404s on controllers. This happens when the controllers are marked @transactional for the restful service to be exposed as a unit of work. Don't fret. Its easy to solve this.

This happens because unlike services which are generally proxied by thier interfaces, Controllers are generally defined without interfaces. The Controller methods are then proxied by cglib (when no interfaces exist) and are no longer visible in their qualified name after instrumention by sonar for code analysis.

Just add proxy-target-class="true" instruction to tx annotation driven in the test context. so the testContext.xml should have the following
<tx:annotation-driven proxy-target-class="true"/>
Where as the main application context can remain without proxying
<tx:annotation-driven/>

Decorator for Memcache Get/Set in python

I have suggested some time back that you could modularize and stitch together fragments of js and css to spit out in one HTTP connection. That makes the page load faster. I also indicated that there ways to tune them by adding cache-control headers. On the server-side however, you could have a memcache layer on the stitching operation. This saves a lot of Resources (CPU) on your server. I will demonstrate this using a python script I use currently on my site to generate the combined js and css fragments. So My stitching method is like this @memize(region="jscss") def joinAndPut(files, ext): res = files.split("/") o = StringIO.StringIO() for f in res: writeFileTo(o, ext + "/" + f + "." + ext) #writes file out ret = o.getvalue() o.close() return ret; The method joinAndPut is * decorated * by memize. What this means is, all calls to joinAndPut are now wrapped (at runtime) with the logic in memize. All you wa...

Faster webpages with fewer CSS and JS

Its easy, have lesser images, css and js files. I will cover reducing number of images in another post. But If you are like me, You always write js and css in a modular fashion. Grouping functions and classes into smaller files (and Following the DRY rule, Strictly!). But what happens is, when you start writing a page to have these css and js files, you are putting them in muliple link rel=style-sheet or script tags. Your server is being hit by (same) number of HTTP Requests for each page call. At this point, its not the size of files but the number server roundtrips on a page that slows your page down. Yslow shows how many server roundtrips happen for css and js. If you have more than one css call and one js call, You are not using your server well. How do you achieve this? By concatinating them and spitting out the content as one stream. So Lets say I have util.js, blog.js and so.js. If I have a blog template that depends on these three, I would call them in three script tags. Wh...
