“The next that thing I am going to be working on is getting the GORM classes to be loaded into the classloader used by the initially loaded class and not just in the dynamically loaded groovy script” -> this would be also important to know if you managed a way to do it

I’ve managed to make it work with those latest versions, what i am facing now in a slightly modified version of your tutorial is:

java.io.FileNotFoundException: class path resource [application.properties] cannot be opened because it does not exist

It loads up all the classes, creates the tables inserts the data, but i am stuck at this error.

I get this exception, tables get created but imediatedly
after:

[java] INFO: schema export complete

i get this:

java.lang.IncompatibleClassChangeError: Found interface groovy.lang.MetaClassRegistry but class was expected

Waht might be the reason?

Hi Jeremie

Thanks for the work. When using an Oracle XE DB the tables get created but then I get the following stack trace… Any ideas why? Does grails/hibernate use an auto-increment key or something unique to MySQL? Is there some hibernate property I am forgetting to set? (groovy-1.5.6 grails-1.0.3)

I have the same problem using Grails 1.0RC3 and a file-based HSQLDB. save(flush:true) didn’t help, any other ideas?

you must add this in the main

props.put(”hibernate.connection.autocommit”,”true”);

and replace this

props.put(”hibernate.hbm2ddl.auto”,”create-drop”);

for this one

props.put(”hibernate.hbm2ddl.auto”,”update”);

John, you may want to try a .save(flush:true). See http://grails.org/doc/1.0.x/ .
