Eclipse roo shell command parameters

[mwarren2]

It appears that you can't set any options when starting the roo shell from within eclipse.

I'd like to be able to send a parameter, or anything, so that when roo reads pom.xml, a 'roo' profile in pom.xml can pick it up.
Or so that I can use Spring expression language to make a choice between two different actions.

For example when roo does database reverse engineering it obviously can't use a jndi ref from Tomcat.
So I want to tell the pom to read from database.properties, and in other circumstances to use the jndi ref.

But I can't work out for the life of me who to tell the pom that this is roo calling.

Anybody got any ideas? Thanks.

Hope nobody minds if I bump this. Anybody got any ideas?

Ok, finally worked it out.

You use spring profiles in applicationContext.xml (available since 3.1).

I have a 'roo' profile which uses a BasicDataSource to call the database without a container
and a 'tomcat' profile which uses JNDI within the Tomcat Container.

The tomcat profile is made active in web.xml with a context-param: <context-param>
<param-name>spring.profiles.active</param-name>
<param-value>tomcat</param-value>
</context-param>

and the roo profile is made active in ROO_HOME/conf/config.properties thus:

#The profile we need to configure the datasource
-Dspring.profiles.active=roo
----------------

Here is the stuff from applicationContext.xml, unfortunately you have to repeat the EntityManagerFactory bean in both profiles otherwise Tomcat says that it can't find it <!-- active profile is set in ROO_HOME/conf/config.properties -->
