grails-2.0

I am trying to execute a raw sql query using something similar to def dataSource; Sql sql = new Sql(dataSource); But, it seems that this runs in a separate transaction of its own. It therefore misses all the (uncommitted) changes done before it in the service method. What is the best way to run a raw sql query in the current transaction? The above code would create a new connection, hence a new transaction. You can use the current Hibernate session(injecting sessionFactory) to execute a raw sql in the current transaction as below. def session = sessionFactory.getCurrentSession() def results =

What would be an intelligent folder structure for grails 2.3.4 in combination with angularjs without using the grails angularjs plugin? Currently I have packed everything into the webapp folder. There are many ways to organize your directories, however, the way we are using, which I'm gonna call it Grailsy way and to some extent is consistent with Grails directory structure is as follow: web-app css js | lib | ng-app | controllers - abcController.js | directives - directives.js | filters - filters.js | services - dataServices.js | views - someHtml.html | app.js the lib has all the angular

I've got an application that was using Grails 1.3.7 which I've just migrated to Grails 2.0. The application makes use of the automatic dateCreated and lastUpdated fields to manage the timestamps associated with creation and modification of the objects. After upgrading, I get the following error: | Running Grails application | Error 2012-01-29 22:36:53,504 [Thread-8] ERROR util.JDBCExceptionReporter - ERROR: null value in column "date_created" violates not-null constraint | Error 2012-01-29 22:36:53,510 [Thread-8] ERROR events.PatchedDefaultFlushEventListener - Could not synchronize database

What is the fastest way to read Images from a File into a BufferedImage in Java/Grails? What is the fastest way to write Images from a BufferedImage into a File in Java/Grails? my variant (read): byte [] imageByteArray = new File(basePath+imageSource).readBytes() InputStream inStream = new ByteArrayInputStream(imageByteArray) BufferedImage bufferedImage = ImageIO.read(inStream) my variant (write): BufferedImage bufferedImage = // some image def fullPath = // image page + file name byte [] currentImage try{ ByteArrayOutputStream baos = new ByteArrayOutputStream(); ImageIO.write( bufferedImage,

The Grails 2.0.4 documentation for validation shows you how to display error messages at the top of the page and how to add a css class to an element if a field is invalid, but it doesn't tell you how to display the error message next to the fields themselves, something like this: ----------------------- Name: | | You must enter a name! ----------------------- How do you retrieve the specific error message for an invalid field and then display it next to the field it's for? Actually, the documentation does show how to do this, it just isn't overly clear that this is what they mean: <g

I'm somewhat newbie for WEB development based on JVM stack, but future project will require specifically some JVM-based WEB engine. So I started looking on some ground to make things quickly and turned to try Grails. Things looked good from the book, but beeing impressed by really long startup time (grails run-app) I decided to test how this works under load. Here it is: test app: follow few instruction here to make it from ground (takes 2 mins assuming you already have Grails and Tomcat installed): _http://grails.org/Quick+Start test case (with Apache benchmark - comes with Apache httpd -
