The book wrongly states that Roo will generate the corresponding accessors and mutators in the Customer_Roo_Entity.aj file. The generated stuff will go into the Customer_Roo_JavaBean.aj file instead.

The book misses to point out an important detail. If Spring responds with a message "Spring Roo automatic add-on discovery service currently unavailable" then you should first issue 'download status' and read the instructions there. To enable the Spring Roo download features you need to type 'download accept terms of use'. Only after performing this last step you will get the output as indicated in the book.

h2 default is ~/test so one must change the path on login to jdbc:h2:tcp://localhost/~/roo_crm
before submitting the SQL

"move all the fields" s/b
"move all the fields and methods"

Note that there is an Eclipse "bug" here. Eclipse tries to be too clever; i.e. when moving cartOrders from Customer_Roo_DbManaged.aj to Customer.java, simply pasting the text adds Company. prefix to all the fields and methods, such as :

@OneToMany(mappedBy = "customerId")
private Set<CartOrder> Customer.cartOrders;


public Set<CartOrder> Customer.getCartOrders() {
return cartOrders;
}

so this must be cleaned up. (STS 2.9.1.RELEASE Build Id: 201203221000 which is based on Eclipse 3.7.2:
Version: 3.7.2.v20120120-1414-7z8gFcuFMP7BW5XTz0jLTnz0l9B1

The command must be:

graph relationship --from ~.model.CartOrder --to ~.model.Product --via ~.model.LineItem --fieldName items --type "ITEMS" --cardinality ONE_TO_MANY

entity --class ~.model.CartOrder
should be
entity jpa --class ~.model.CartOrder
