Widlfly远程EJB查找抛出NoSuchEJBException：问题是什么？

标签： java java-ee ejb wildfly jndi

我不知道为什么我的查询抛出NoSuchEJBException：我的Bean部署在wildfly上。管理员控制台显示服务器已注册该bean：在运行时/服务器/ EJB下它被列为EJB，因此我假定它已正确部署。但是，当我远程查找它时，仍然会收到NoSuchEJB-Exception。我不知道在哪里寻找解决方案。

我的EJB部署在jar中。 .jar文件被称为“ Markup2”，Bean被命名为“ MarkupGeneratorBean”。这是一个远程无状态会话Bean。

这里是堆栈跟踪：

这是我的Serlvet进行查找的方法：

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;}

我的pom.xml包含以下依赖项：

  • 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

我的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

我的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

非常感谢您！

编辑：这是Bean的JNDI绑定

java:global/Markup2/MarkupGeneratorBean!com.markupGenerator.MarkupGeneratorRemote
java:app/Markup2/MarkupGeneratorBean!com.markupGenerator.MarkupGeneratorRemote
java:module/MarkupGeneratorBean!com.markupGenerator.MarkupGeneratorRemote
java:jboss/exported/Markup2/MarkupGeneratorBean!com.markupGenerator.MarkupGeneratorRemote
ejb:Markup2/MarkupGeneratorBean!com.markupGenerator.MarkupGeneratorRemote
java:global/Markup2/MarkupGeneratorBean
java:app/Markup2/MarkupGeneratorBean
java:module/MarkupGeneratorBean

编辑：在此期间，我已经能够成功进行远程EJB调用。不要问我如何：我真的不知道为什么它能奏效。我切换到CDI解决方法。在不同应用程序中的同一服务器上成功进行EJB调用后，我想在出现上述错误的应用程序中再次尝试。后来，在我重新启动服务器后，它在两个应用程序中均停止工作-出现与上述相同的错误。

更新：我能够在另一台服务器上进行远程EJB调用。这意味着，我一定在不知不觉中将原始服务器弄乱了。
