ClosedChannelException on FluentProducerTemplate with Apache Camel

I'm facing ClosedChannelException with my app, when I'm testing Apache Camel route.
rest().post("/{{camel.rest.version}}/ufx")
.type(MyMsg.class)
.consumes(MediaType.APPLICATION_XML_VALUE)
.produces(MediaType.APPLICATION_XML_VALUE)
.responseMessage().code(HttpStatus.SC_OK).responseModel(MyMsg.class).endResponseMessage()
.responseMessage().code(HttpStatus.SC_BAD_REQUEST).responseModel(MyMsg.class).endResponseMessage()
.route().routeId("rst_myrest")
.to("direct:route_myroute")
.endRest();
onException(ValidationException.class).
handled(true).
log(LoggingLevel.ERROR, LoggingConst.ERROR +" Validation exception: ${body}").
onExceptionOccurred(validationExceptionProcessor).
marshal().jaxb(MyMsg.class.getPackage().getName()).
log(LoggingLevel.INFO, "Error response ${body}").
end();
from("direct:route_myroute").routeId("rt_ufx")
.unmarshal().jaxb(MyMsg.class.getPackage().getName())
.process("myvalidator")
//some other lines
.marshal().jaxb(MyMsg.class.getPackage().getName())
.end();
In my test, invalid data is passed, so ValidationExceptionProcessor is invoked.
public class ValidationExceptionProcessor implements Processor {
#Override
public void process(Exchange exchange) throws Exception {
ValidationException request = exchange.getException(ValidationException.class);
MyMsg msg = new MyMsg();
//preparing some pretty object
exchange.getOut().setBody(msg);
exchange.getOut().setHeader("CamelHttpResponseCode", HttpStatus.BAD_REQUEST);
}
}
It works fine when I'm invoking my app directly (from Postman, for example). Correct MyMsg object is logged and returned to user.
Junit-test FluentProducerTemplate is used to check the result:
#RunWith(CamelSpringBootRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
#DirtiesContext
#Slf4j
#UseAdviceWith
public class myTest {
#Produce(uri = "undertow:myaddress")
FluentProducerTemplate holdProducer;
#Test
public void invalidDataException() throws IOException, InterruptedException {
Exchange send = holdProducer.withHeader(Exchange.HTTP_METHOD, HttpMethod.POST)
.withHeader(Exchange.CONTENT_TYPE, MediaType.APPLICATION_XML_VALUE)
.withBody(Files.readAllBytes(Paths.get("src/test/resources/Request.xml")))
.send();
Exception exception = send.getException(); //here I get java.nio.channels.ClosedChannelException
}
}

What is the difference between invoking from Fluent and a running app directly? How can it be fixed?
P.S.Changing message output to In() doesn't help

I found a solution, but not in the place I was looking for. Here is my Http code set:
exchange.getOut().setHeader("CamelHttpResponseCode", HttpStatus.BAD_REQUEST);
HttpStatus.BAD_REQUEST is a Spring enum entry. And the result is a enum value:
BAD_REQUEST(400, "Bad Request"),
When my app was run inside Spring container, Spring did the enum-value unmarshal and I received a correct body with Http-400 code.
However with FluentProducerTemplate (with belongs to camel-libraries), no unmarshalling was done, and fluent crashes somewhere. (I do wonder where and why exactly. And why the error is so weird).
Switching to Camel header solved my problem
exchange.getOut().setHeader("CamelHttpResponseCode", HttpStatus.SC_BAD_REQUEST);
because Camel httpHeaders are not a enum, but a public-static-final field
public static final int SC_BAD_REQUEST = 400;
it also works fine if you call .value() for Spring enum
exchange.getOut().setHeader("CamelHttpResponseCode", HttpStatus.BAD_REQUEST.value());

java.lang.RuntimeException: Could not inject members

I'm trying since some time to get Arquillian running with JPA.
I had some DAO tests working, but while a continued to write the remaining tests this error started and affected both the ones I was writing and the ones that were fine before.

My tests look all the same:

import javax.inject.Inject;

archive.addPackages(true, "br.com.cpmh.beacon");
archive.addAsResource("test-persistence.xml", "META-INF/persistence.xml");
archive.addAsResource(EmptyAsset.INSTANCE, ArchivePaths.create("beans.xml"));

public void setUp() throws Exception
{
//morphologicalAnalysisPersistenceFacade = new MorphologicalAnalysisPersistenceFacade();
}
#After

}

I think the most important part in this stacktrace is:
WELD-001408: Unsatisfied dependencies for type MorphologicalAnalysisPersistenceFacade
This usually means that not all required dependencies for MorphologicalAnalysisPersistenceFacade are deployed to the Weld-container. To debug this I would suggest temporarily rewriting your deployment method to:
#Deployment
public static Archive<?> createDeployment() {
JavaArchive archive = ShrinkWrap.create(JavaArchive.class, "morphological-analysis-data-access-object-test.jar")
.addPackages(true, "br.com.cpmh.beacon")
.addAsResource("test-persistence.xml", "META-INF/persistence.xml")
.addAsResource(EmptyAsset.INSTANCE, ArchivePaths.create("beans.xml"));
// print all included packages
System.out.println(archive.toString(true));

This will print out all the classes which are deployed to the container. With that, you can investigate if any required class does not get deployed and include that class or package manually in your createDeployment method.

How to get global variables from jbpm-process within WorkItem

I can successfully retrieve global variables (such as NodeInstance, ProcessInstance and so on) from within the process with help of Script-Task and kcontext-instance; But what if I need retrieve those global variables within WorkItem? I could of course put Script-Task before my WorkItem within Process and then assign a global variable to one of Variable Definitions, in order to use it within WorkItem with getParameter()-method;
But we do understand, that it is double made work, doesn't we?
So how could I get global variables within WorkItem without additional Script-Task? I thought firstly, that I could use the same name of the session within WorkItem, such we define by registering WorkItem in KieWorkBench, that's why I created a ProcessContext within my WI as follows:
KieServices ks = KieServices.Factory.get();
KieContainer kContainer = ks.getKieClasspathContainer();
KieSession kSession = kContainer.newKieSession("ksession-process");
ProcessContext context = new ProcessContext(kSession);
Map<String, Object> params = new HashMap<>();
public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {
params.put("lane", context.getNodeInstance().getNode().getMetaData().get("Lane").toString());
manager.completeWorkItem(workItem.getId(), params);
}
With this code snippet within executeWorkItem(), but rather with kcontext in Script-Task I can retrieve successfuly the name of the Lane and assign it to variable, but when I execute the process with this WorkItem I get an Error - WorkItem -- null not by deploying, rather by starting the process; Of course I also registry the same ksession - name as within WorkItem (namely "ksession-process") in KieWorkBench, but apparently I cannot use the context this way, as I thought.
So I really appreciate your help! It doesn't really bother, but to make a code resp. BProcess a little bit concisely and without any redundant variables, it pays to ask.
jBPM 6.4, wildfly 8.2
UPDATE:
as user livthomas has suggested, instead of WorkItemHandler interface I've tried to extend my class to AbstractWorkiItemHandler as follows:
public class WI extends AbstractWorkItemHandler {
public WI(StatefulKnowledgeSession ksession) {
super(ksession);
}
KieSession kSession = getSession();
ProcessContext context = new ProcessContext(kSession);
Map<String, Object> params = new HashMap<>();
public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {
params.put("lane", context.getNodeInstance().getNode().getMetaData().get("Lane"));
manager.completeWorkItem(workItem.getId(), params);
}
...
And then register it in Project's descriptor.xml as new my_package.WI(ksession);
Unfortunately I get the RuntimeException: cannot instance WorkItem...

You need to either extend AbstractWorkItemHandler or implement your work item handler in a similar way. Then just pass ksession instance as a parameter of its constructor when you register it. Once you have a reference to KIE session, you can get global variables calling its getGlobals() method.

nested exception is org.hibernate.exception.SQLGrammarException: could not execute query

This is the error I am getting. I have been stuck for 2 hours but could not resolve it.My code for hibernate is as follows:-
Session session1=new Configuration().configure("hibernate.cfg.xml").buildSessionFactory().openSession();
org.hibernate.cfg.Configuration cfg=new org.hibernate.cfg.Configuration();
cfg.configure("hibernate.cfg.xml");
//creating seession factory object
SessionFactory factory=cfg.buildSessionFactory();
//creating session object
Session session=factory.openSession();
String hql = "SELECT E.id FROM User E where firstName=:name";
SQLQuery query = session1.createSQLQuery(hql);
query.setParameter("name", name);
List results = query.list();
Iterator itr=results.iterator();
String id="";
while(itr.hasNext()){ id=String.valueOf(itr.next());}
//creating transaction object
Transaction t=session.beginTransaction();
User employee =
(User)session.get(User.class, 2);
employee.setMessage(chat);
session.update(employee);
//template.save(e1);
//session.persist(user);//persisting the object
t.commit();//transaction is committed
session.close();
return "hello";
Any help would be appreciated..thanx in advance.
