從 Jboss 4.2.3 遷移到 Wildfly 8

Question

我正在嘗試將一個非常舊的 java 應用程序從 Jboss 4.2.3 遷移到 Wildfly 8。我剛剛安裝了 Wildfly 服務器和最小的配置。

在我的應用程序中，我的 JNDI.properties 文件是：

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost:1099

所以我將其更新為：

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

調用 EJB 的代碼是：

Properties ht = new Properties();
ht.load(BIServicesImpl.class.getClassLoader().getResourceAsStream("jndi.properties"));
Context context = new InitialContext(ht);
return (ServiceEntryPoint) context.lookup("BIServeurMetier/ServiceEntryPointBean/remote");

Wildfly 8 中的 JNDI 路徑已更改，因此我使用了：

Properties ht = new Properties();
ht.load(BIServicesImpl.class.getClassLoader().getResourceAsStream("jndi.properties"));
Context context = new InitialContext(ht);
return (ServiceEntryPoint) context.lookup("BIServeurMetier/BIServeurMetier/ServiceEntryPointBean!com.al6.bi.business.ServiceEntryPoint"); 

我將我的應用程序戰爭部署到其中，然后啟動它，它運行得很好：

2022-06-27 16:21:00,773 INFO  [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-3) JNDI bindings for session bean named ServiceEntryPointBean in deployment unit subdeployment "BIServeurMetier.jar" of deployment "BIServeurMetier.ear" are as follows:

    java:global/BIServeurMetier/BIServeurMetier/ServiceEntryPointBean!com.al6.bi.business.ServiceEntryPoint
    java:app/BIServeurMetier/ServiceEntryPointBean!com.al6.bi.business.ServiceEntryPoint
    java:module/ServiceEntryPointBean!com.al6.bi.business.ServiceEntryPoint
    java:jboss/exported/BIServeurMetier/BIServeurMetier/ServiceEntryPointBean!com.al6.bi.business.ServiceEntryPoint
    java:global/BIServeurMetier/BIServeurMetier/ServiceEntryPointBean
    java:app/BIServeurMetier/ServiceEntryPointBean
    java:module/ServiceEntryPointBean

因此，EJB 接縫可以很好地部署。 但是，當我嘗試對應用程序執行任何操作時，出現此錯誤：

EJB 的路徑似乎不錯，因為它在服務器啟動時顯示在服務器日志的開頭。 那么我做錯了什么？

我還通過 JNDI 中的管理控制台檢查，我的 EJB 在這里並列出。

Answer 1

JNP 是舊的 JNDI 實現，您需要更新您的 jndi.properties。 我認為對於 WildFly 8，它是：final Properties env = new Properties(); env.put(Context.INITIAL_CONTEXT_FACTORY, org.jboss.naming.remote.client.InitialContextFactory.class.getName()); env.put(Context.PROVIDER_URL, "remote://localhost:4447"); remoteContext = new InitialContext(env);

Answer 2

除了 ehsavoie 回答之外，我還需要欺騙一些東西才能使其正常工作。

我按照這里的教程：

https://docs.jboss.org/author/display/WFLY10/EJB%20invocations%20from%20a%20remote%20client%20using%20JNDI.html

和這里 ：

https://docs.jboss.org/author/display/WFLY10/Remote%20JNDI%20Reference%20Update%20Draft.html

事實上，在我的情況下，我不需要http遠程模式，只是一個簡單的EJB模式，所以不需要在JNDI.properties中放入復雜的參數。

我刪除了我的 jndi.properties 文件，並將代碼更新為：

final Hashtable jndiProperties = new Hashtable();
jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
final Context context = new InitialContext(jndiProperties);
return (ServiceArchiveEntryPoint) context.lookup("ejb:BIServeurMetier/BIServeurMetier//ServiceArchiveEntryPointBean!com.al6.bi.business.ServiceArchiveEntryPoint");

在我在該代碼之前的第一次嘗試中，它不起作用。 我認為這是因為我沒有放正確的路徑。 規則似乎是：

context.lookup("ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);

在此之前，我沒有放一個“distinctName”，但似乎如果我們沒有，就放一個空字符串，所以在我的情況下它給出了“//”。

也許是這樣，也許是“ejb：”前綴，我不知道是哪個更改使它起作用，但它現在起作用了。
