Java 在WildFly 8.2.0最终版本中添加模块

我是JBoss新手，我尝试在WidlFly 8.2.0中为derby添加一个jdbc驱动程序作为一个模块

我所做的：

• 我在JBOSS_HOME/modules/system/layers/base目录中添加了org/apache/derby/main文件夹
• 在这个新文件夹中，我添加了derbyclient.jar（来自JDK1.8.0_40，它包含驱动程序）和一个新的

  module.xml

  文件

module.xml

文件如下：

 <?xml version="1.0" encoding="UTF-8"?>
 <module xmlns="urn:jboss:module:1.0" name="org.apache.derby">
     <resources>
         <resource-root path="derbyclient.jar"/>
     </resources>
     <dependencies>
         <module name="javax.api"/>
     </dependencies>
 </module>

当我启动WildFly时，出现以下错误：

你知道我做错了什么吗

提前感谢

您的URL

jdbc:derby://:MyDB

看起来无效。

我最终通过以下方式解决了问题：

• 在独立目录（部署我的应用程序的地方）中添加derbyclient.jar
• 修改standalone.xml中的datasource声明以使其引用jar名称：

jdbc:derby:MyDB；create=true derbyclient.jar…

（我删除了

标签，我不再使用它了。）

所以，当我开始使用WildFly时，我不再有错误了。derby驱动程序没有声明为模块，但它将在我的不同应用程序之间共享，所以这没关系。

derbyclient.jar是否位于您的WAR的正确位置？我想一定是在“图书馆”存放的地方。嗨，布莱恩，谢谢你的回答。事实上，不，它不是在战争中，我想让部署在WildFly实例中的所有应用程序都使用jar，所以我想将它声明为WildFly的一个模块。derbyclient.jar位于JBOSS_HOME/modules/system/layers/base/org/apache/derby/mainHi-Hwellmann中，感谢您的回答。你是对的，url是错误的。但是，在修复了它（jdbc:derby:MyDB；create=true）之后，我仍然有相同的错误。您是否单独尝试了驱动程序/URL组合（使用DriverManager，而不使用WildFly）？您似乎混淆了Derby的嵌入式和客户端/服务器使用。
