我正在尝试设置 Jboss 服务器“客户端”(版本 5.1.0)以使用来自另一个 Jboss 服务器(10.90.0.91)的远程 EJB,但我无法使用Jboss 客户端。
我可以在我的客户端上使用这个简单的代码获取远程 EJB:
InitialContext ctx = null;
try {
Hashtable<String, String> jndiProps = new Hashtable<String, String>();
jndiProps.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
jndiProps.put(InitialContext.PROVIDER_URL, "jnp://10.90.0.91:1099");
ctx = new InitialContext(jndiProps);
return ctx.lookup(jndiName);
} catch (NamingException e) {
throw new RuntimeException(e);
}
这很好用。
现在我想用这个属性设置 Jboss 客户端。但是,如果我从以下位置编辑 server/{application}/conf/
上本地化的现有 jndi.properties 文件:
# DO NOT EDIT THIS FILE UNLESS YOU KNOW WHAT YOU ARE DOING
#
java.naming.factory.initial=org.jboss.iiop.naming.ORBInitialContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
收件人:
# DO NOT EDIT THIS FILE UNLESS YOU KNOW WHAT YOU ARE DOING
#
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jnp://10.90.0.91:1099
当我启动 Jboss 客户端时收到一些错误(显然,我不知道我在做什么 :)):
2016-08-19 10:17:41,645 ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] (main) Error installing to Start: name=HASessionStateService state=Create

在 final 中:
2016-08-19 10:17:51,993 ERROR [org.jboss.system.server.profileservice.ProfileServiceBootstrap] (main) Failed to load profile: Summary of incomplete deployments (SEE PREVIOUS ERRORS FOR DETAILS):
DEPLOYMENTS MISSING DEPENDENCIES:
Deployment "ProfileServiceInvocationHandler" is missing the following dependencies:
Dependency "ProfileServiceProxyFactory" (should be in state "Configured", but is actually in state "**ERROR**")
Dependency "ProfileServiceProxyFactory" (should be in state "Configured", but is actually in state "**ERROR**")
DEPLOYMENTS IN ERROR:
Deployment "jboss:service=ClientUserTransaction" is in error due to the following reason(s): javax.naming.NameAlreadyBoundException: UserTransaction

Deployment "ProfileServiceProxyFactory" is in error due to the following reason(s): javax.naming.NameAlreadyBoundException: ProfileService, **ERROR**
所以,我认为我不能触及该文件上已经存在的 JNDI 属性。
如果因为 JBoss 本身正在使用 jndi.properties 文件而无法更改,我可以在哪个位置将 JNDI 查找设置设置为 Jboss 5 中的远程 EJB?如何在不将 jndi.properties 文件放入 WAR 文件的情况下将 jndi.properties 文件配置为在应用程序类路径中可用?
谢谢!
最佳答案
另一种方法是在您的 jboss-service.xml 文件中配置 org.jboss.naming.ExternalContext
MBean:
<mbean code="org.jboss.naming.ExternalContext"
name="jboss.jndi:service=ExternalContext,jndiName=external/server2">
<attribute name="JndiName">external/server2</attribute>
<attribute name="Properties">
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jnp://10.90.0.91:1099
<!-- other properties as needed -->
</attribute>
<attribute name="InitialContext"> javax.naming.IntialContext </attribute>
<attribute name="RemoteAccess">false</attribute>
</mbean>
执行查找的 java 代码将变为:
Context initialContext = new InitialContext();
return initialContext.lookup("external/server2/" + jndiName);
设置时,您甚至可以在本地管理控制台中使用 JNDIView 导航远程 JNDI 树。
更多信息可以在 org.jboss.naming.ExternalContext MBean 中找到.
