![]() ![]() But as a result of those gaps, I wasn't able to reap this book's full benefits. Not to be too much of a self-apologist, but let me preface this review by indicating that my frustration (and hence my lower rating) comes largely from gaps in my own knowledge. Also available is all code from the book. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. The book also covers using Grails with existing Javatechnology, like Spring, Hibernate, and EJBs. Then it walks readers through a Twitter-style social networkingapp-built in Grails, of course-where they implement high-interest featureslike mashups, AJAX/JSON, animation effects, full text search, rounded corners,and lots of visual goodness. The book starts with an overview of Grails and how it can help you get your webdev mojo back. It coversthe nuts and bolts of the core Grails components and is jam-packed withtutorials, techniques, and insights from the trenches. Grails in Action is a comprehensive look at Grails for Java developers. Developers are instantly productive, picking up all the benefits of theRuby-based Rails framework without giving up any of the power of Java. To use this you must add two special parameters to your Config.For web developers used to wrestling with Java and XML, Grails is a breath offresh air. Jawr will only serve requests containing this prefix. You can define a URL fragment as a prefix (such as ‘/jawr/’) to prefix every URL. Note that Jawr handles individual files (you don’t need to explicitly define a bundle for every file you want to compress and serve standalone), so that should not keep you from using this mapping method. This is specially useful if you are adding Jawr to an existing application and you do not want to change every existing script tag. This is the usual approach, but you may want to bundle only part of your code and serve the rest normally. ![]() This is the default behavior, and you don’t need to configure anything at all for it to work, simply omit the jawr.js.mapping/ properties from your config and you are ready to go. css, thus letting Jawr control all requests to your resources. You can have Jawr respond to all requests ending in.There are two ways to map Jawr to requests: To enable the Jawr Binary servlet, which handle images and fonts, you need to define one of the following property : * * .image * jawr.binary.* (Any property which starts with jawr.binary) So to enable the JS or the CSS servlet, you must at least define a bundle of the specified type. So if you configure only JS bundle, the plugin will start only the Jawr JS servlet. The configuration will indicate to the plugin which Jawr servlet to start. All jawr packages start with net.jawr.*, so you can use that as a key for an appender. Jawr uses sl4j to log messages, so you can configure its tracing level along with the rest of your application. If you add none of the jawr.css.* parameters, for instance, Jawr will do no effort to serve CSS files. Note that you are not forced to use Jawr for both js and css files. Using this syntax, you will be able to define bundles as specified in the relevant documentation pages. : Jawr will use Grails’ Locale resolution strategy when it applies.: The value set for will be used for this attribute (which is ‘utf-8’ by default in Grails).This happens automatically when you start Grails in development mode (but keep in mind that the changes are applied after you refresh a page in your browser). In Grails, Jawr will instead listen to changes to the oovy script to reload its configuration. properties file to reload it when it changes. : The Jawr servlet can be configured to listen to changes to the.Keep in mind that there are a few property keys that don’t apply when using Jawr with Grails. Of course, the property values must be quoted in order to avoid syntax errors. Check the config file syntax page for details. properties file used in standard java web applications. The syntax you must use is exactly the same described for the. To configure Jawr you must add properties to the oovy file located at the /conf folder of your application.
