Embedded Set with Spring Roo (Scaffolding)

Embedded Set with Spring Roo (Scaffolding)

I am struggling to scaffold a Class with an „embedded List“.

I have a Product where a scaled Price should be persisted and scaffolded (MVC) within the Product-Class.

Spring roo Vs (Wicket and Spring)

Spring roo is new framework and I found it very interesting.

Roo cannot find com.mysql.jdbc.Driver

Download either the .tar or the .zip from here: http://www.mysql.com/downloads/connector/j/ Extract the jar to some path and launch roo and run this command:

Code:

osgi start --url file:///C:/path/to/mysql-connector-java-5.1.13-bin.jar

After this roo should be able to do all the database commands.

Spring Roo Mapping Url

In Spring Roo app, we should use "/" instead of "?", because when switch language (eg. by add "?lang=JP") we will not be change to another page.

Spring Roo use "lang" as a reversed word

Default, Spring Roo use "lang" parameter to switch languages. If use this parameter, in all forms we should not use "lang" as element of form.

We can change this default in file: context.xml and language tag.
