This is the reason why in Clerezza I created a factory which made it possible to pass the ClassLoader as an additional parameter for instantiating an AE [1]. This is quite "custom" and I don't like it very much to pass ClassLoaders between bundles however it could be good to implement a OSGiUIMAFrameworkImpl class which hides such details to the developer who wants to run UIMA inside OSGi environments. 2011/7/20 Jörn Kottmann <kottm...@gmail.com> > > Maybe something we should do for UIMA 3.0, because we might want to > break backward compatibility for it. > > > +1 Tommaso [1] : http://svn.apache.org/repos/asf/incubator/clerezza/trunk/parent/uima/uima.utils/src/main/java/org/apache/clerezza/uima/utils/UIMAExecutorFactory.java
