I don't get why my lookup throws a NoSuchEJBException: My Bean is deployed on wildfly. The admin-console shows that the server has registered the bean: It is listed as EJB under runtime/server/EJB, so I assume that it is deployed correctly. But I still do get a NoSuchEJB-Exception when I look it up remotely. I don't know where to look for a solution.

My EJB is deployed in a jar. The .jar-File is called "Markup2", the Bean is named "MarkupGeneratorBean". It is a remote and stateless session-bean.

Here the stacktrace:

javax.ejb.NoSuchEJBException: EJBCLIENT000079: Unable to discover destination for request for EJB StatelessEJBLocator for "/Markup2/MarkupGeneratorBean", view is interface com.markupGenerator.MarkupGeneratorRemote, affinity is None

Here's the method of my serlvet that is doing the lookup:

private Document getRenderDocument() {

Document doc = null;

try {



  Context context = new InitialContext();





  MarkupGeneratorRemote mB = (MarkupGeneratorRemote) context.

      lookup("ejb:/Markup2//MarkupGeneratorBean!com.markupGenerator.MarkupGeneratorRemote");



  doc = Jsoup.parse(mB.generateDocumentFromUrl("http://localhost:8080/html-files/intro.html"));



  doc.getElementById("pretestform").html(qItem.getHtml() + "<input type="submit" value="let's go!">");



} catch (NamingException e) {

  // TODO Auto-generated catch block

  e.printStackTrace();

}

return doc;}

My pom.xml contains the following dependencies:

• jsoup:1.11.3 maven-war-plugin:3.0.0


• maven-plugin-api:3.0


• htmlunit:2.32


• serializer.2.7.2


• derbyclient:10.14.1.0


• wildfly-client.all:12.0.0.Final


• javax.persistence-api:2.2

My jndi.properties:

java.naming.provider.url = http-remoting://127.0.0.1:8080

java.naming.factory.initial =  org.jboss.naming.remote.client.InitialContextFactory

java.naming.factory.pkgs=org.jboss.ejb.client.naming

my jboss-ejb-client.properties:

endpoint.name=client-endpoint

remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false

remote.connections=default

remote.connection.default.host=127.0.0.1

remote.connection.default.port=8080

remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false

Thank you very much in advance!!

EDIT: Here are the JNDI-Bindings of the Bean

EDIT: In the meantime I had been able to make successful remote EJB-invocations. Don't ask me how: I really don't know why I it did work. I switched to a CDI-workaround. After making a successful EJB-call on the same server in a different application, I wanted to try it again in the app that had the error above. Later, it stopped working in both apps after I had restarted the server - getting the same error as described above.

UPDATE: I was able to make remote EJB-invocations on another server. That means, that I must have messed something up on the original server unknowingly.
