Hi guys, I’m trying to check a simple json response without success: HTTP response: status= 200 OK headers= Server: [Apache-Coyote/1.1] Content-Type: [application/json] Transfer-Encoding: [chunked] body= [{“ctrDthAtu”:“2015-05-12T12:30:04.000+0000”,“nroIntTur”:11673,…other attrs}] I’ve tried jsonPath(“$.nroIntTur”).ofType[Int].saveAs(“nroIntTur”) but got: > KO jsonPath($.nroIntTur).find(0).exists, found nothing as my response is an array of jsonObjects I’ve also tried the array notation: jsonPath(“$[0].nroIntTur”).ofType[Int].saveAs(“nroIntTur”) but i get this stacktrace: > Uncaught error from thread [GatlingSystem-akka.actor.default-dispatcher-5] shutting down JVM since ‘akka.jvm-exit-on-fatal-error’ is enabled for ActorSystem[GatlingSystem] > java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/servlet/http/HttpServlet > at java.lang.ClassLoader.defineClass1(Native Method) > at java.lang.ClassLoader.defineClass(ClassLoader.java:760) > at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) > at java.net.URLClassLoader.defineClass(URLClassLoader.java:467) > at java.net.URLClassLoader.access$100(URLClassLoader.java:73) Any help is appreciated refs: [http://goessner.net/articles/JsonPath/](http://goessner.net/articles/JsonPath/) > **[GitHub - gatling/jsonpath: A JSONPath interpretor in Scala](https://github.com/gatling/jsonpath)** > > A JSONPath interpretor in Scala.

Wat Where does this HttpServlet thingy comes from? Gatling has nothing to do with servlets? Could you provide the full statcktrace, please? ---

I also receive the same exception when the response is not an array, eg: {“ctrDthAtu”:“2015-05-12T12:30:04.000+0000”,“nroIntTur”:11673… and the check $.nroIntTur ---

found the problem, maven dependency conflict, removing dep below solves the problem: ```auto javax javaee-api 6.0 provided ``` ---

Yep. I’ll provide a fix for Boon, but until then, please remove the dep if you can. Or use another jar such as the JBoss/WildFly ones. ---

Hi Stephane, indeed jboss javaee6 api solved it: org.jboss.spec jboss-javaee-6.0 3.0.3.Final pom Note that using Javaee7-api gives a clear error: javax javaee-api 7.0 provided Uncaught error from thread [GatlingSystem-akka.actor.default-dispatcher-11] shutting down JVM since ‘akka.jvm-exit-on-fatal-error’ is enabled for ActorSystem[GatlingSystem] java.lang.ExceptionInInitializerError at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at org.boon.core.Sys.detectContainer(Sys.java:207) at org.boon.core.Sys.(Sys.java:196) at org.boon.core.value.LazyValueMap.buildMap(LazyValueMap.java:225) at org.boon.core.value.LazyValueMap.entrySet(LazyValueMap.java:214) at java.util.AbstractMap.containsKey(AbstractMap.java:144) at io.gatling.jsonpath.JsonPathWalker.walk1(JsonPath.scala:63) at io.gatling.jsonpath.JsonPathWalker.io$gatling$jsonpath$JsonPathWalker$$walk(JsonPath.scala:52) at io.gatling.jsonpath.JsonPathWalker$$anonfun$io$gatling$jsonpath$JsonPathWalker$$walk$1.apply(JsonPath.scala:52) at io.gatling.jsonpath.JsonPathWalker$$anonfun$io$gatling$jsonpath$JsonPathWalker$$walk$1.apply(JsonPath.scala:52) at scala.collection.Iterator$$anon$12.hasNext(Iterator.scala:396) at scala.collection.Iterator$$anon$1.hasNext(Iterator.scala:870) at scala.collection.Iterator$$anon$14.skip(Iterator.scala:476) at scala.collection.Iterator$$anon$14.hasNext(Iterator.scala:477) at scala.collection.Iterator$class.toStream(Iterator.scala:1188) at scala.collection.AbstractIterator.toStream(Iterator.scala:1202) at scala.collection.TraversableOnce$class.toSeq(TraversableOnce.scala:283) at scala.collection.AbstractIterator.toSeq(Iterator.scala:1202) at io.gatling.core.check.extractor.jsonpath.SingleJsonPathExtractor$$anonfun$extract$1.apply(JsonPathExtractor.scala:53) at io.gatling.core.check.extractor.jsonpath.SingleJsonPathExtractor$$anonfun$extract$1.apply(JsonPathExtractor.scala:53) at io.gatling.core.validation.Success.map(Validation.scala:32) at io.gatling.core.check.extractor.jsonpath.SingleJsonPathExtractor.extract(JsonPathExtractor.scala:53) at io.gatling.core.check.extractor.CriterionExtractor.apply(Extractor.scala:33) at io.gatling.core.check.CheckBase$$anonfun$check$2$$anonfun$apply$2$$anonfun$apply$4.apply(Check.scala:84) at io.gatling.core.check.CheckBase$$anonfun$check$2$$anonfun$apply$2$$anonfun$apply$4.apply(Check.scala:83) at io.gatling.core.validation.Success.flatMap(Validation.scala:33) at io.gatling.core.check.CheckBase$$anonfun$check$2$$anonfun$apply$2.apply(Check.scala:83) at io.gatling.core.check.CheckBase$$anonfun$check$2$$anonfun$apply$2.apply(Check.scala:82) at io.gatling.core.validation.Success.flatMap(Validation.scala:33) at io.gatling.core.check.CheckBase$$anonfun$check$2.apply(Check.scala:82) at io.gatling.core.check.CheckBase$$anonfun$check$2.apply(Check.scala:81) at io.gatling.core.validation.Success.flatMap(Validation.scala:33) at io.gatling.core.check.CheckBase.check(Check.scala:81) at io.gatling.http.check.HttpCheck.check(HttpCheck.scala:35) at io.gatling.http.check.HttpCheck.check(HttpCheck.scala:32) at io.gatling.core.check.Check$.checkRec$1(Check.scala:37) at io.gatling.core.check.Check$.check(Check.scala:59) at io.gatling.http.ahc.AsyncHandlerActor.checkAndProceed$1(AsyncHandlerActor.scala:281) at io.gatling.http.ahc.AsyncHandlerActor.io$gatling$http$ahc$AsyncHandlerActor$$processResponse(AsyncHandlerActor.scala:322) at io.gatling.http.ahc.AsyncHandlerActor$$anonfun$receive$1.applyOrElse(AsyncHandlerActor.scala:89) at akka.actor.Actor$class.aroundReceive(Actor.scala:467) at io.gatling.core.akka.BaseActor.aroundReceive(BaseActor.scala:22) at akka.actor.ActorCell.receiveMessage(ActorCell.scala:516) at akka.actor.ActorCell.invoke(ActorCell.scala:487) at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:254) at akka.dispatch.Mailbox.run(Mailbox.scala:221) at akka.dispatch.Mailbox.exec(Mailbox.scala:231) at scala.concurrent.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) at scala.concurrent.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1339) at scala.concurrent.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1979) at scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107) Caused by: java.util.MissingResourceException: Can’t find bundle for base name javax.servlet.LocalStrings, locale pt\_BR at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1564) at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1387) at java.util.ResourceBundle.getBundle(ResourceBundle.java:773) at javax.servlet.GenericServlet.(GenericServlet.java:95) … 52 more ---
