How do I use Spring Roo DBRE add-on in Roo 1.1.0 RELEASE? -

-

i've heard of roo dbre add-on , think great feature provided roo. couldn't find documentation on google roo dbre. how use feature? have checked jira ticket https://jira.springframework.org/browse/roo-1685 , said documentation created can find it?

also when type database introspect --schema public --file schema.xml

roo tells me command 'database introspect --schema public --file schema.xml' found not available (type 'help' enter learn command)

what mean? need manually install add-on?

i think missing 1 of create project or jpa set steps. first have create project , jpa set after edit generated datapase.properties , database introspect. hint command guide next step. 

roo> project com.***.***** created root/pom.xml created src_main_resources created src_main_resources/log4j.properties created spring_config_root created spring_config_root/applicationcontext.xml  roo> hint roo requires installation of persistence configuration, example, jpa.  jpa, type 'jpa setup' , hit tab 3 times. suggest type 'h' tab complete "hibernate". after --provider, press tab twice database choices. testing purposes, type (or tab) hypersonic_in_memory. if press tab again, you'll see there no more options. such, you're ready press enter execute command.  once jpa installed, type 'hint' , enter next suggestion.  roo> jpa setup --provider hibernate --database mssql
