Re: What jar is ca.uhn.hl7v2.parser.Parser in?

How about just loading the converter when the component is load?
Since the component is loaded when the camel context need it, it will
help us to avoid the annoying class load error.

Yes, it is important to support load the camel component dynamically.
Maybe we need to change the META-INF files to put the schema, language,
typeconverts into the component files.

I assume he gets this issue since he just adds all the camel-xxx.jars
in the classpath.

So if he removes camel-hl7.jar then the problem disappears.

Would make sense to be able to load a component in isolation so it will register
- scheme
- type converters
- languages
- etc. etc.

We might wanna take a look at this in the future. Hadrian would also
like components to be able to add:
- dynamic DSL

So somekind of architecture for loading components on the fly is
probably what we gonna look at in the long run
