Extend the servicemix-commons to provide better classloading semantics
----------------------------------------------------------------------
Key: SM-591
URL: https://issues.apache.org/activemq/browse/SM-591
Project: ServiceMix
Issue Type: Improvement
Affects Versions: 3.0
Reporter: Philip Dodds
Fix For: 3.1
Add a getConfigurationClassLoader to the ServiceUnit class in
org.apache.servicemix.common. This can be used to ensure that is a ServiceUnit
is going to contain Java Code then it needs to ensure that it provides a
classloader.
This method can then be used in the AsyncBaseLifeCycle in the method
processExchange:
Refactor the processExchange to be doProcessExchange and then create a new
processExchange akin to this:
ClassLoader oldCl = Thread.currentThread().getContextClassLoader();
try {
if (getServiceUnit().getConfigurationClassLoader()!=null) {
ClassLoader classLoader =
endpoint.getServiceUnit().getConfigurationClassLoader();
Thread.currentThread().setContextClassLoader(classLoader);
}
doProcessExchange(exchange);
} finally {
Thread.currentThread().setContextClassLoader(oldCl);
}
