[JBoss JIRA] Created: (WELDX-74) Support use of decorator of Callable<T>

Support use of decorator of Callable<T>
---------------------------------------
Key: WELDX-74
URL: https://jira.jboss.org/jira/browse/WELDX-74
Project: Weld Extensions
Issue Type: Feature Request
Components: Java SE
Reporter: Elias Ross
Decorator exists for Runnable. Should allow for Callable<T> to be used as well.
This is actually pretty useful, for example if you want to execute under a temporary new scope in the same thread, e.g.
@Inject Instance<PaymentProcessor> paymentProcessorSource; // which implements Callable<Result>
Result result = paymentProcessorSource.get().call();
Or, in the case of a thread pool, you can use Future<T> etc.
/**
* Decorator for all beans which implements Callable. It intercepts the call
* to the call() method to set up the ThreadContext for the new thread so that
* instances of @ThreadScoped beans can be correctly resolved.
*/
@Decorator
public class CallableDecorator<T> implements Callable<T> {
@Inject @Delegate Callable<T> callable;
/**
* Set up the ThreadContet and delegate.
*/
public T call()
{
// set up context for this thread
final ThreadContext threadContext = WeldSEBeanRegistrant.THREAD_CONTEXT;
threadContext.setBeanStore(new HashMapBeanStore());
threadContext.setActive(true);
// run the original thread
try {
return callable.call();
} finally {
threadContext.destroy();
}
}

[JBoss JIRA] Created: (WELDX-38) ConversationScoped not working on Tomcat

ConversationScoped not working on Tomcat
----------------------------------------
Key: WELDX-38
URL: https://jira.jboss.org/jira/browse/WELDX-38
Project: Weld Extensions
Issue Type: Bug
Components: Servlet Containers
Affects Versions: Servlet Containers 1.0.0.CR1
Environment: Apache Tomcat 6.0.20
Reporter: Fabio Wang
Trying to mark a conversation as long-running causes an exception (java.lang.NoClassDefFoundError: javassist/util/proxy/ProxyObject) when the ServletConversationManager tries to get a proxy for the httpSession.
The ProxyFactory.classLoaderProvider ends up resolving the classloader to an instance of org.apache.catalina.loader.StandardClassLoader (which doesn't know the javassist lib, since it's only in the app classloader).

[JBoss JIRA] Created: (WELD-516) RunnableDecorator incorrectly assumes >0 Runnable beans
by Morten Christensen (JIRA)
RunnableDecorator incorrectly assumes >0 Runnable beans
-------------------------------------------------------
Key: WELD-516
URL: https://jira.jboss.org/jira/browse/WELD-516
Project: Weld
Issue Type: Bug
Affects Versions: 1.0.1.Final
Environment: Java 6 + WeldSE
Reporter: Morten Christensen
The class org.jboss.weld.environment.se.threading.RunnableDecorator incorrectly assumes that there will be at least one bean that implements Runnable.
If there are no beans that implements Runnable then an error like this will happen:
org.jboss.weld.DeploymentException: Injection point has unstatisfied dependencies. Injection point: field org.jboss.weld.environment.se.threading.RunnableDecorator.runnable; Qualifiers: [@javax.enterprise.inject.Default()]
at org.jboss.weld.Validator.validateInjectionPoint(Validator.java:232)
at org.jboss.weld.Validator.validateBean(Validator.java:80)
at org.jboss.weld.Validator.validateRIBean(Validator.java:100)
at org.jboss.weld.Validator.validateBeans(Validator.java:282)
at org.jboss.weld.Validator.validateDeployment(Validator.java:267)
at org.jboss.weld.bootstrap.WeldBootstrap.validateBeans(WeldBootstrap.java:389)

at org.jboss.weld.environment.se.StartMain.go(StartMain.java:45)
at org.jboss.weld.environment.se.StartMain.main(StartMain.java:57)
I guess the field "runnable" inside this class should be changed to use Instance<Runnable> instead.
