Running weld + solder + wicket on GAE
by Marek Śmigielski
Hi,
I have managed to deploy and successfully test simple injection of
weld-servlet, seam-wicket and solder module to GAE. This task involves
making some modifcations in all of this modules.
1. seam-solder
In AbstractJndiBeanManagerProvider I have added catch for
NoClassDefFoundError just after NamingException. GAE can't initialize
InitialContext.
>> java.lang.NoClassDefFoundError: Could not initialize class com.google.apphosting.runtime.security.shared.stub.javax.naming.InitialContext
2. seam-wicket
I have added service ServletContextBeanManagerProvider which resolves
BeanManager from ServletContext as JNDI based providers does not work.
3. weld-core
I have changed catching exception from ResourceLoadingException to
Throwable. It is widest possible catch declaration, in fact catching
specific exceptions would be probably better or GAE exceptions should
be catch deeper and rethrown as ResourceLoadingException.
There is problem with adding this classes during deployment:
org.jboss.seam.solder.bean.generic.GenericBeanExtension$1
org.jboss.seam.solder.util.collections.AbstractMultiset$ElementSet$1
org.jboss.logging.JBossLogManagerProvider
org.jboss.seam.solder.bean.defaultbean.DefaultBeanExtension$1
org.jboss.seam.solder.util.collections.AbstractMultimap$KeySet$1
org.jboss.logging.Log4jLogger
org.jboss.logging.JBossLogManagerLogger
>>Caused by: java.security.AccessControlException: access denied (java.lang.RuntimePermission accessDeclaredMembers)
4. weld-core
In InstantiatorFactory I have commented out adding
ReflectionFactoryInstantiator. It is not allowed to use
ReflectionFactory on GAE. Adding reflection factory should be check
programmatically before creating new instance in some if clause.
>> java.lang.NoClassDefFoundError: sun.reflect.ReflectionFactory is a restricted class. Please see the Google App Engine developer's guide for more details.
>> at com.google.appengine.runtime.Request.process-609c29691be26e8f(Request.java)
>> at sun.reflect.ReflectionFactory.<clinit>(ReflectionFactory.java)
>> at java.lang.reflect.Method.invoke(Method.java:43)
>> at org.jboss.weld.util.reflection.instantiation.ReflectionFactoryInstantiator.<init>(ReflectionFactoryInstantiator.java:45)
I have not tested yet which solder features are working and which ones
not. In wicket page injection works as expected.
If you are interested in providing support for GAE, I think it would
be great to have this changes apply to master branch. Some of them
(especially 3 and 4) need some more development and propably support
from weld team.

submodule for each service in Social
by Antoine Sabot-Durand
Hi all,
I'm gonna create a lot of binding object for each social services in Social, and a remark from Marek Schmidt made me wonder if it could be a good choice to create a specific submodule (i.e. jar) for each service ?

Debug page for CDI.
by Marek Śmigielski
Hi,
Is there any way in Seam 3 or CDI itself to list active beans in all
scopes for debug purposes? I remember that it was debug page in Seam 2
with such functionality. If it isn't available, have you any
suggestions about the way of resolving list of beans either in all
scopes or in particular scope?
thanks,

Registered a bean at runtime
by Antoine Sabot-Durand
Hi,
I'll need to dynamically create scoped CDI beans. I guess I have to use the @New qualifier but as I didn't found example in other modules (was looking for the Seam Groovy module port), I was wondering if it's a good practice. Feedback or example are welcome.

Naming convention and package organization advice
by Antoine Sabot-Durand
Hi Team,
in Seam social I created bean to deal with social network. I named those Bean with "Handler" suffix : i.e. TwitterHandler. I choose this over "Service" or "Controller" but as there will be other Seam module dealing with high level functional services, I prefer check this naming convention with you. Sharing the same naming convention across modules to have something homogenous is something important.
