Adding new properties from AppModule
I have a few execution environments like prod, qa, dev and such and I want to
set a certain property based on that. Basically I want to set config
property progrematically inside QAMode,ProdMode and DevMode
@Contribute(HibernateSessionSource.class)
public void
addHibernateSessionSource(OrderedConfiguration<HibernateConfigurer> conf,
@Value("${config}") final String executionMode) {
conf.add("HibernateConfig", new HibernateConfigurer() {
@Override
public void configure(org.hibernate.cfg.Configuration
configuration) {
configuration.configure("scripts/db/" + config +
"/hibernate.cfg.xml");
}
});
}
Thanks for help.
Cheers

Re: Adding new properties from AppModule
Posted by bhorvat <ho...@gmail.com>.
I will try to add a bit more content.
What I am trying to do is create environments for my development, and one of
the key aspect here would be the database connection.
So in my hibernate.cfg.xml file I need to set hibernate.connection.url, so I
would like to set it using the properties or for example
hibernate.connection.username and hibernate.connection.password.
So in this way I will have one hibernate.cfg.xml and use the diff modules to
set it up. So can I set this one up somehow with MappedConfiguration<K,V> or
use System.setProperty()?

> How can I add new properties
This question is pretty vague, most likely you will use a
MappedConfiguration<K,V> which allows you to contribute to a service which
takes a Map<K,V> in it's constructor.

Quick answer: In the order that they are needed. Tapestry IOC is lazy, none
of your services are instantiated initially. Instead, tapestry creates a
proxy which will only instantiate your service implementation the first time
a method is invoked on the proxy.
You can force a service to load using eager loading
(http://tapestry.apache.org/defining-tapestry-ioc-services.html#DefiningTapestryIOCServices-EagerLoadingServices)
Tapestry includes a page in your application where you can check the status
of your services (http://tapestry.apache.org/service-status.html)

You shouldn't rely on that. That's why OrderedConfiguration exists.

Re: Adding new properties from AppModule

Ok then my question remains. How can I add new properties, is there any way
to add some custom properties or should I simply use System.setPropertie...
Also one other question what is the order of the model load?
AppModule, ExecutionModelus, SubModules defined in AppModule? Also does it
load everything from one module or does it go method by method?
For example it first calls bind() in all modules and then it moves on to
contributeApplicationDefaults?
tnx for fast response
cheers

No, I'm saying you should analyze what values and/or services are needed in
each of your scenarios and Tapestry gives you the flexibility to
do exactly what you want or need.

No.

Just use ordinary Java code reuse: put the shared code inside a method in
some class and call this method in any class you need. Code duplication
avoided.

This is what execution modes are about.
Execution modes map to modules; those modules are only loaded if the
execution mode is active. It is entirely for these particular kinds of
environmental customizations.
