Thank you willem....
I am able to write in a file using CamelContextFactory...
I am adding the way i did for future reference.
1) Create an Activator class which implements BundleActivator.
Store the BundleContext variable in a static variable added by us in the
Activator class.
Do the following code where u want to create the CamelContext instance
bundleContext = Activator.getBundleContext(); //static
BundleContext
camelContextFactory = new CamelContextFactory();
camelContextFactory.setBundleContext(bundleContext);
camel = camelContextFactory.createContext();
camel.addComponent("file", new FileComponent());
camel.start();
