I wanted to see how swagger works, but is having trouble with the "camel-example-servlet-rest-tomcat" quickstart example. After packaging it, and placing the WAR file in Tomcat 8.0.22. I was able play with the rest service without any problem.
BUT, I was not able to get the "http://localhost:8080/camel-example-servlet-rest-tomcat/api-docs"; swagger API page working. It shows a NullPointerException. Is there a specific version of Tomcat that we need to use? java.lang.NullPointerException org.apache.camel.component.swagger.RestSwaggerReader$$anonfun$createParameters$2.apply(RestSwaggerReader.scala:190) org.apache.camel.component.swagger.RestSwaggerReader$$anonfun$createParameters$2.apply(RestSwaggerReader.scala:179) scala.collection.TraversableLike$WithFilter$$anonfun$foreach$1.apply(TraversableLike.scala:772) scala.collection.Iterator$class.foreach(Iterator.scala:727) scala.collection.AbstractIterator.foreach(Iterator.scala:1157) scala.collection.IterableLike$class.foreach(IterableLike.scala:72) scala.collection.AbstractIterable.foreach(Iterable.scala:54) scala.collection.TraversableLike$WithFilter.foreach(TraversableLike.scala:771) org.apache.camel.component.swagger.RestSwaggerReader.createParameters(RestSwaggerReader.scala:179) org.apache.camel.component.swagger.RestSwaggerReader$$anonfun$read$2.apply(RestSwaggerReader.scala:123) org.apache.camel.component.swagger.RestSwaggerReader$$anonfun$read$2.apply(RestSwaggerReader.scala:70) scala.collection.TraversableLike$WithFilter$$anonfun$foreach$1.apply(TraversableLike.scala:772) scala.collection.mutable.ResizableArray$class.foreach(ResizableArray.scala:59) scala.collection.mutable.ArrayBuffer.foreach(ArrayBuffer.scala:47) scala.collection.TraversableLike$WithFilter.foreach(TraversableLike.scala:771) org.apache.camel.component.swagger.RestSwaggerReader.read(RestSwaggerReader.scala:70) org.apache.camel.component.swagger.RestApiListingCache$$anonfun$listing$1$$anonfun$apply$1.apply(RestApiListingCache.scala:42) org.apache.camel.component.swagger.RestApiListingCache$$anonfun$listing$1$$anonfun$apply$1.apply(RestApiListingCache.scala:41) scala.collection.immutable.List.foreach(List.scala:318) scala.collection.generic.TraversableForwarder$class.foreach(TraversableForwarder.scala:32) scala.collection.mutable.ListBuffer.foreach(ListBuffer.scala:45) org.apache.camel.component.swagger.RestApiListingCache$$anonfun$listing$1.apply(RestApiListingCache.scala:41) org.apache.camel.component.swagger.RestApiListingCache$$anonfun$listing$1.apply(RestApiListingCache.scala:38) scala.Option.orElse(Option.scala:257) org.apache.camel.component.swagger.RestApiListingCache$.listing(RestApiListingCache.scala:38) org.apache.camel.component.swagger.RestSwaggerApiDeclarationServlet.renderResourceListing(RestSwaggerApiDeclarationServlet.scala:171) org.apache.camel.component.swagger.RestSwaggerApiDeclarationServlet.doGet(RestSwaggerApiDeclarationServlet.scala:98) javax.servlet.http.HttpServlet.service(HttpServlet.java:622) javax.servlet.http.HttpServlet.service(HttpServlet.java:729) org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) org.apache.camel.component.swagger.RestSwaggerCorsFilter.doFilter(RestSwaggerCorsFilter.scala:44) -- View this message in context: http://camel.465427.n5.nabble.com/Problem-with-swagger-in-the-camel-example-servlet-rest-tomcat-tp5767376.html Sent from the Camel - Users mailing list archive at Nabble.com.
