Hi The JDK language is not really suited well for DSL like and you can only stretch it as far we have done with Camel. There are some cases where you cannot just keep adding methods and expect the scope to appear correctly.
You can use onException instead of try .. catch stuff and have error handling logic in another place and keep route logic clean. Then the DSL in Java should be possible to do more easily.
