[jira] [Commented] (CAMEL-9856) RestSwaggerProcessor fails with
"Provider org.apache.xalan.processor.TransformerFactoryImpl not found"
[ https://issues.apache.org/jira/browse/CAMEL-9856?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16177972#comment-16177972 ]
Martin Lichtin commented on CAMEL-9856:
---------------------------------------
Running into the same issue with Camel 2.18.4.
The problem appears as soon as one documents a query param.
E.g. this works:
{noformat}
<get outType="MyType[]">
<route>
<to uri="bean:myBean?method=list(${header.where}, ${header.orderBy})" />
</route>
</get>
{noformat}
and one can retrieve the Swagger JSON.
But when adding a <param> the Swagger interface does no longer work:
{noformat}
<get outType="MyType[]">
<param name="where" type="query" required="true" />
<param name="orderBy" type="query" required="false" />
<route>
<to uri="bean:myBean?method=list(${header.where}, ${header.orderBy})" />
</route>
</get>
{noformat}
The full exception is:
{noformat}

> 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).
