20080301662 | METHOD FOR VERSIONING CLASSES LOADED IN AN OSGI-ENABLED J2EE ENVIRONMENT - According to exemplary embodiments, a method is provided for versioning classes in an OSGi-enables J2EE environment. A first version of code is packaged into a first OSGi bundle, and the first version of code is marked for export. A second version of code is packaged into a second OSGi bundle, and the second version of code is not marked for export. A determination is made whether an application needs the first version of code or the second version of code. If the application needs the first version of code, a classloader hierarchy is constructed using existing classloaders. If the application needs the second version of code, a new classloader is created which is able to load application classes and unversioned application server classes normally, while only loading the correct version of versioned code. | 12-04-2008 |
