Dynamically updating seam context

[teknokrat]

Does seam provide any hooks for dynamically updating its context without redeploying everything. For example, if I want to create a new component at runtime. can i add to the seam context somehow? Is it possible to provide seam with a list of classpaths to look for new components?

cheers

Check out the docs for hot deployment without redeploying.

You can construct Components by instantiating them...there are several constructors that are public, for example:

Component newComponent = new Component(SomeClass.class,"myComponentName");

Note that this isn't a documented API, is probably discouraged, and is in general subject to change.  That having been said, it's a lot of fun, will teach you a lot about how Seam works, and can be used for cool tricks (for example, we use it to allow our test cases to use @In to grab DAOs to aid in setting up test scenarios.)  You should take a look at how Init.installComponents, because some component functionality like @Filter and @Autocreate won't work if you don't call some methods in Init.

Actually Component is a documented class in the Seam API, so it is part of the public interface I believe...

http://docs.jboss.com/seam/latest/api/org/jboss/seam/Component.html

Although those JavaDocs could be better documented.  How does creating a new Component compare to simply creating an object and adding it to a context instance like

myContext.set( 'bob', myObj );

When a new instance is added to the context, do @In annotations get processed?
