Subject [jira] [Commented] (CAMEL-9856) RestSwaggerProcessor fails with "Provider org.apache.xalan.processor.TransformerFactoryImpl not found"
Date Wed, 13 Apr 2016 08:59:25 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-9856?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15238893#comment-15238893
] 

Ralf Steppacher commented on CAMEL-9856:
----------------------------------------

Hi [~davsclaus], I cannot see a commit on the ticket. Is the "fix" the addition of a working
example? In other workds, does this mean I must have screwed up my context setup somewhere
to end up with the error? Or was it actually broken for OSGi environments and I have to wait
for 2.18.0 to be released? Thanks!

> When I try to query the Swagger API output for my REST routes, which are defined in a
Blueprint context with the XML DSL, any request to a path that I think should return API information
yields an empty response body (status 200) on the client and this error on the server. The
error is raised by {{RestSwaggerSupport::getRestDefinitions(String)}} (line 147).
