我在 E:\jboss-as-7.1.1.Final\standalone\deployments 文件夹中制作war文件并复制和过去，自动部署成为启动并出现此错误：

nested exception is java.lang.NoClassDefFoundError: com/sun/net/ssl/internal/ssl/Provider

i try to add path in edit jboss_home/modules/sun/jdk/main/module.xml and add path com/sun/net/ssl/internal , but error is not remove

我尝试在编辑 jboss_home/modules/sun/jdk/main/module.xml 中添加路径并添加路径 com/sun/net/ssl/internal ，但错误未删除

So how to remove this error?

那么如何消除这个错误呢？

Jboss 7 looks for dependencies in the modules folder. You can't just go in the modules.xml file and add new modules if they don't actually exist.

Jboss 7 在 modules 文件夹中查找依赖项。如果新模块实际上不存在，您不能直接进入 modules.xml 文件并添加新模块。

What you need to do is find out whether there is a jar containing the missing class, if it exist then you need to add a reference to that module from your project, if does not exist, you need to manually download it and copy it to the modules directory and then reference it.

您需要做的是找出是否有包含缺少类的jar，如果存在则需要从项目中添加对该模块的引用，如果不存在，则需要手动下载并复制到模块目录，然后引用它。

You have several ways you can reference it:

您可以通过多种方式引用它：

Add a classpath entry to your manifest file: Classpath: com.sun.net
Add a global reference to that module in your standalone.xml by adding a Global module.

将类路径条目添加到您的清单文件： Classpath: com.sun.net
通过添加Global 模块，在您的 standalone.xml 中添加对该模块的全局引用。

I just faced this problem in jboss 7.1.1Final . I was getting it for X509TrustManager.java from com.sun.net.ssl package from rt.jar inside jdk 7.

我刚刚在 jboss 7.1.1Final 中遇到了这个问题。我从 jdk 7 中的 rt.jar 的 com.sun.net.ssl 包中为 X509TrustManager.java 获取了它。

I solved it by adding

我通过添加解决了它

<module xmlns="urn:jboss:module:1.1" name="sun.jdk">

in module.xml under modules/sun of jboss 7.

在 jboss 7 的 modules/sun 下的 module.xml 中。

Hope this will help anyone :)

1.Open module definition for sun.jdkmodule. For latest EAP, path is : JBOSS_HOME\modules\system\layers\base\sun\jdk\main\module.xml

1.打开sun.jdk模块的模块定义。对于最新的 EAP，路径是：JBOSS_HOME\modules\system\layers\base\sun\jdk\main\module.xml

Add following to paths section :

将以下内容添加到路径部分：

<path name="com/sun/ssl/internal/ssl"/>
<path name="com/sun/net/ssl"/>

2.Add following to jboss-deployment-structure.xml inside your WEB-INF folder

2.将以下内容添加到 WEB-INF 文件夹内的 jboss-deployment-structure.xml

<dependencies>

The problem what I see is java.lang.NoClassDefFoundError: com/sun/net/ssl/internal/ssl/Provideryou need to add dependencies in your web app's manifest file, My suggestion is, read that section from the manual first

我看到的问题是java.lang.NoClassDefFoundError: com/sun/net/ssl/internal/ssl/Provider您需要在 Web 应用程序的清单文件中添加依赖项，我的建议是，首先阅读手册中的该部分

To import it using jboss-deployment-structure.xml:

<dependencies>

  <module name="system" >

     <imports>

        <include-set>

           <path name="com/sun/ssl/internal/ssl"/>

         </include-set>

      </imports>

    </module>

</dependencies>

That class has been provided with all Oracle/Sun JDks since 1.4, i.e. 8-9 years.

自 1.4（即 8-9 年）以来，所有 Oracle/Sun JDks 都提供了该类。

Either:

任何一个：

You are using a non-Sun/Oracle JDK
You are using the classname com.sun.net.ssl.internal.ssl.Provider in your code or configuration file(s), or
You have something seriously wrong with your Java installation

您使用的是非 Sun/Oracle JDK
您在代码或配置文件中使用类名 com.sun.net.ssl.internal.ssl.Provider，或
您的 Java 安装存在严重问题
