Jim Newsham commented on CAMEL-4026:
------------------------------------
Claus, I'm not aware of any way to start a webstart app programmatically from
Java. I've been doing a full deployment for my testing. This involves: (1)
building your code into a jar; (2) signing *all* jars (your jar and third party
jars) with the *same* certificate; you can use a self-generated certificate for
this; (3) creating a webstart descriptor file (*.jnlp) which points to your
jars and main class; (4) configuring/deploying the JnlpDownloadServlet on a
servlet container such as tomcat (this servlet is needed to support the
version-based download protocol [1]); (5) deploying your jars and jnlp on the
servlet container; (6) using a browser to request the jnlp file.
More info can be found in the webstart dev guide:
http://download.oracle.com/javase/1,5.0/docs/guide/javaws/developersguide/contents.html
Obviously this is a lot of work. We have ant scripts that automate most of
this for us, but they are tied to our build process (using ivy for pulling in
dependencies, for example), so I can't just send that to you.
[1] Note that the problem I reproduced was with the version-based protocol. I
have not tried without the version-based protocol, but I suspect the problem
might not exist without.

> Project: Camel

> This is a regression. Worked fine for us in Camel 2.5.0, fails in Camel
> 2.7.1.
> Easy to reproduce. Run the following code in a webstart-deployed application:
> CamelContext context = new DefaultCamelContext();
> context.getTypeConverterRegistry();
> Which produces the following exception:
