Question

为了向多个应用程序显示外部jar，我通常将外部jar放在JBOSS 5.x的$ JBOSS_HOME / server / default / lib directoy中。这些jar在AS的startp处自动启动。我将如何在wildfly-9.0.2.Final中做。

@Sam Thankx回复但我仍然得到错误，请看我的方案如下结构

在test.ear
在test.jar中有EJB3会话bean java类。在这个类中有import stmt as。

import com.oracle.asmc.ejb3.statelesssession.SLE3DecryptLocal;
上面的包'com.oracle.asmc.ejb3.statelesssession.SLE3DecryptLocal'出现在testclient.jar中

注意 - 上面的testclient.jar不是test.ear的一部分。（我想从多个EAR访问这个testclient.jar）

要部署test.ear，我已完成以下步骤

./ jboss-cli.sh -c（出现在bin目录中）
module add --name = testclient --resources =〜/ client_jar / testclient.jar

我在jboss-deployment-structure.xml中添加了以下配置，并在创建test.ear时放置在META-INF目录中。

<?xml version="1.0"?>       
   <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
  <deployment>
  <dependencies>
       <module name="testclient" />
  </dependencies>
</deployment>
</jboss-deployment-structure>

为了部署Test.ear应用程序，访问了“http://127.0.0.1:9990/”并进行了travesed链接Deployments - ＆gt;添加 - ＆gt;添加部署---＆gt;完成但仍然有以下错误。

@Sam thankx回复

我在test.jar的META-INF中添加了'jboss-deployment-structure.xml'。

注意 - 是的，我正在从test.jar访问'com / oracle / asmc / ejb3 / statelesssession / SLE3DecryptLocal'（存在于testclient.jar模块中）。

现在我的test.ear包含

META-INF / application.xml中
test.war
test.jar（此test.jar的META-INF目录中存在'jboss-deployment-structure.xml'）

但我仍然遇到以下错误。

使用WildFly完全改变了类加载。您可以阅读[at]

的更多信息

从WildFly 8开始，类加载与以前版本的JBoss AS有很大不同。类加载基于JBoss Modules项目。 WildFly的类加载不是更熟悉的分层类加载环境，而是基于必须在其他模块上定义显式依赖关系的模块。 WildFly中的部署也是模块，除非定义了对这些类的显式依赖，否则无法访问应用程序服务器中jar中定义的类。

可以在WildFly 9 Documentation

上找到更多信息

基本上，您可以使用共享库添加模块，并使部署依赖于它。

例如，您可以使用jboss-cli（位于bin文件夹中）添加带有MySQL Connector Java的模块

module add --name=org.mysql --resources=mysql-connector-java-5.1.31-bin.jar --dependencies=javax.api,javax.transaction.api

然后，为了让您的应用程序看到它，您可以添加一个名为jboss-deployment-structure.xml的文件，其中包含以下信息：

<?xml version="1.0"?>

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
    <deployment>
        <dependencies>
            <module name="org.mysql" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>

模块名称必须与您在模块添加命令中指定的名称匹配。

如果您在jboss-deployment-structure.xml部分的MANIFEST.MF中添加模块名称，则可以省略文件Dependencies

在wildfly-9.0.2.Final
