Subject [jira] [Commented] (CXF-6567) Allow alternate wildcard in Camel CXF Transport for Blueprint
Date Tue, 01 Sep 2015 09:32:45 GMT

    [ https://issues.apache.org/jira/browse/CXF-6567?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14725068#comment-14725068
] 

Akitoshi Yoshida commented on CXF-6567:
---------------------------------------

The proposed solution would need a more fine tuning to avoid getting someone's mischievously
typed "ME_WILDCARD_ENDPOINT" incorrectly converted to an "ME_*_ENDPOINT".

So, instead of devising an escaping exception rule, I think we should just add a configurable
datatype validation option (blueprint.aries.xml-validation-datatypes) in aries blueprint.
That will solve this problem and also tthe other problem (i.e., handling of the properties
placeholders) at the same time.

Maybe Dan or Christian who work on Aries can also comment here?
regards, aki

> We are trying to use Camel CXF Transport within Blueprint. 
> We followed the intructions on this page : 
> http://camel.apache.org/camel-transport-for-cxf.html
> However, when defining a camel destination with an ID containing an asterisk and dot
: 
> <camel:destination id="*.camel-destination" camelContextId="camel1" />
> Blueprint XSD validation fails with the exception below [1]. 
> In Spring, an ID is defined as a "xs:string", whereas in Blueprint, an ID is defined
as "NCName" (non-colonized name), which disallows "asterisk". 
> Here is a patch to support an alternate wildcard which uses only characters allowed ("__WILDCARD__")
to replace the asterisk ("*").
> <camel:destination id="__WILDCARD__.camel-destination" camelContextId="camel1" />
