Grails, charts technologies

Recently, I faced the problem of using charts in Grails web-application. At first, I was thinking about using well-known java libraries, such as JFreeChart . JFreeChart has a nice look, nice written documentation, and pretty simple to use.

Grails, jackson, json technologies

Optimizing Web application request processing time is an important stage of quality product development. While doing this part of the work on one of our products we noticed that the huge bottleneck was buried inside built-in JSON support in Grails. The problem was that built-in JSON parser that comes with Grails is surprisingly slow. Thats why we considered switching to using Java-based JSON parser instead.

Grails, mongodb technologies

There is some twist to use more specific data storage engines than RDBMS. The mongodb is a modern feature-rich non-RDBMS database. It can be used with grails quite well, though some special care should be taken. In this post we will create base secure grails application powered by mongodb.

Grails, mongodb, nosql technologies

If you are going to use mongodb for production grails application you might stuck with the issue that replica set is really not supported by current version 1.0.0.M1 of mongodb plugin.

It is quite surprising because mongo java driver supports replica set configuration quite fine.

The problem is that GORM plugin is built on top of version 0.5.1 of gmongo library which doesn't support replica set. Only current development version 0.7 of gmongo library supports this feature.
