Claus Ibsen commented on CAMEL-4576:
------------------------------------
You wanna create a new exception instance on the fly and provide a String for
its constructor. And that String parameter is constructed using the Simple
language.
Which use-case do you need this for? Eg to use <throwException> in a Camel
route?
> Make exception throwing as flexible in XML as in Java DSL

> Key: CAMEL-4576
> URL: https://issues.apache.org/jira/browse/CAMEL-4576
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Affects Versions: 2.8.1
> Environment: N/A
> Reporter: David J. M. Karlsen
> Labels: exception, throwException, xml
>
> When throwing exceptions there are more options in the java DSL (one has full
> control) than in the XML where you can only reference an exception instance.
> It would be useful to be able to construct the exception and throw it, so
> that one could add messages to it - preferably like:
> {noformat}
> throwException class="someEx" message="someProblem ${body}
> ${in.header.someHeader}
> {noformat}
> Reference: http://camel.apache.org/exception-clause.html
