I am writing an application on Google App Engine using Grails. Everything works great on my local dev environment. However on live server, I get exception when trying to upload file. When Grails runtime tries to parse controller params, it uses Apache.Commons.FileUpload, which writes temp file and Google doesn't like it. What is the be...
I realize that this may be tantamount to asking, "what's the best programming language?" (lots of debate and emotion), but I don't know what do but ask YOU about what Web Frameworks you've had good experience with. Practically, to be adopted by our IT folks it needs to be HOSTED on Java; thus the two I listed in the subject above. I ins...
I'm trying to use the taglib call there's attribute parameters, but also the stuff inside the tag itself which the link taglib uses. I can't find the attribute to pass in to a g.link() call to have it render the text of the link. I've tried 'body' and 'link' and 'text' and 'linkText' already - none of those work. I'm expecting to be ...
I don't have any experience with MVC, and am trying to use Grails to write a simple web app. All the examples I've found assume you have a database to base your domain classes off of, and there for have a model based on a database. I'm getting data through an API that does socket communication, and would want the model to be based on tha...

What I want to do is make a call to the flex app with my parameters and have the flex ap...

So here's an example: views/index.gsp views/index.js views/home/index.jsp views/home/index.js But when I simply add the index.js script reference like this: <script src="index.js" type="te...

Consider the following usages of the Grails/GORM dynamic finder method findAllBy*: def foo1 = Foo.findAllByYear(yyyy) def foo2 = Foo.findAllByMonth(mm) def foo3 = Foo.findAllByDay(dd) def foo4 = Foo.findAllByYearAndMonth(yyyy, mm) def foo5 = Foo.findAllByYearAndDay(yyyy, dd) def foo6 = Foo.findAllByYearAndMonthAndDay(yyyy, mm, dd) prin...
By default, grails seems to return <class name>:<id> for toString() of an Java domain object. That's not at all what I want of course, so I tried to @Override the toString() to return what I want. When I tried grails generate-all Tagtype, I got the following error: java.lang.LinkageError: loader constraint violation: loader (instance of...
We're using Grails but with an existing model layer and DAO layer. We have an app written already in Spring MVC, using Spring for IoC and also Security. I'm trying to port the control and view over to Grails as a proof of concept. I have Grails working fine with IoC but am having some trouble getting Grails to work with Spring Securit...

I'm using some legacy java code that consists of several static classes from with in a Grails app under tomcat. When I only have one user using the web application everything works fine. When two users use the application things start to go wrong. I believe it's because the static classes maintain resource locks such as sockets. Am I cor...
