Subject [jira] Commented: (MYFACES-2290) Add OSGi bundle information and bundle classloader / activator
Date Wed, 28 Oct 2009 01:34:03 GMT

    [ https://issues.apache.org/jira/browse/MYFACES-2290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12770744#action_12770744
] 

Leonardo Uribe commented on MYFACES-2290:
-----------------------------------------

We can't add public classes on javax.faces package, because the classes there are dictated
by JSR-252, but maybe we can add classes under org.apache.myfaces on myfaces-api jar. 

We have to ask dev list how to deal with this. At this point we have the following options:

1. add the required classes as public under org.apache.myfaces package myfaces-api.jar
2. Create one or two jar specific for OSGi, that deal with this.

I'll ask this to dev list to see what we can do.

> The provided patch will add OSGi information to bundle manifest. A bundle activator class
makes the MyFaces framework aware that it is running in a bundle environment. A bundle classloader
is used to load classes and resources from the bundle classpath. The patch doesn't require
any new runtime dependencies and doesn't affect class loading in a non-OSGi environment. Though,
small modifications to classloading were needed. This was mainly replacing Thread.currentThread.getContextClassLoader()
with ClassUtils methods.
> To run MyFaces in an OSGi environment both bundles (myfaces-api and myfaces-impl) have
to be started in the OSGi container. Additionally, the myfaces-impl bundle has to be made
available to myfaces-api. Use a fragment bundle with myfaces-api as Fragment-Host and myfaces-impl
as Required-Bundle.
