我想在 Weblogic 10.3.2 (11g) 上启用 Seam 调试页面。所以，我做了以下事情：
我在我的 ejb 和 web maven 项目（都是我的超级项目的模块）中都有 jboss-seam 和 jboss-seam-debug jar 作为依赖项我把这个上下文参数放在我的 web.xml 中：
<context-param>
<param-name>org.jboss.seam.core.init.debug</param-name>
<param-value>true</param-value>
</context-param>
现在，当我点击我的应用程序的 URL 时，我得到了带有此异常的调试页面（帖子末尾的完整堆栈跟踪）：
由 java.lang.IllegalStateException 与 消息：“没有阶段 id 绑定到当前 线程（确保你没有两个 SeamPhaseListener 实例 已安装）”
从我读到的帖子看来，这似乎与类路径中的两个 jboss-seam 或 jboss-seam-debug 罐有关。我打开了我的 ear 文件，每个文件中只有一个存在（在 ear 中），而 war 本身在 WEB-INF/lib 中没有库。
我还阅读了另一种使用 components.xml 初始化调试页面的方法。我还尝试在 WEB-INF 中包含以下 components.xml，但它也不起作用：
<?xml version="1.0" encoding="UTF-8"?>
<components xmlns="http://jboss.com/products/seam/components"
xmlns:core="http://jboss.com/products/seam/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://jboss.com/products/seam/core
http://jboss.com/products/seam/core-2.2.xsd
http://jboss.com/products/seam/components
http://jboss.com/products/seam/components-2.2.xsd">
<core:init debug="true"/>
</components>
关于如何正确启用调试页面的任何建议？
干杯！

更新 1：
现在调试页面根本没有出现。当我要求http://localhost/myapp/debug.xhtml 时，我得到一个页面：
myapp/debug.xhtml
与任何不存在的页面相同。我打开了 .ear，下面的 jboss jar 在：

更新 2：
here 这些家伙也有同样的问题。他们有一个包含内部 WAR 项目的外部 EAR 项目。他们讨论这可能与 jars 在项目中的最终结果有关。
我使用 Maven，并且我已将其设置为创建“Skinny Wars”，即从内部 WAR 项目中排除所有 jar 依赖项，以便它保持较小的大小。它的所有依赖项都包含在 EAR 中，并被所有其他模块使用。
我更改了 maven-war-plugin 的设置，将特定于 web 的 jars（链接中提到的那些，如 RichFaces、jboss-seam-debug、Facelets 等）留在 war 中。
但是，问题已恢复到以前的形式。我现在得到调试页面，无论我按什么链接，但最初的例外情况。
由 java.lang.IllegalStateException 引起，带有消息：“没有阶段 id 绑定到当前线程（确保您没有安装两个 SeamPhaseListener 实例）”
更新 3： 应用.ear的结构如下：
application.ear
|--> APP-INF
| |--> classes
|--> lib (all jar dependencies go here, including the WAR dependencies, EJB module dependencies)
|-->META_INF
| |--> application.xml
| |--> data-sources.xml
| |--> MANIFEST.MF
| |--> weblogic.xml
| |--> weblogic-application.xml
|--> jboss-seam-2.2.0.GA.jar
|--> myEjbModule1.jar
|--> myEjbModule2.jar
|--> myEjbModule3.jar
|--> myEjbModule4.jar
|--> myWar.war (NO libraries in WEB-INF/lib, finds everything in EAR/lib)
在没有启用调试的情况下部署 .ear 应用程序时（不包括 ear 中的 jboss-seam-debug.jar），应用程序被正确加载。
在 EAR（EAR/lib 目录）中部署 WITH jboss-seam-debug.jar 时，应用程序不出现，而只出现调试页面，异常如下（最后是堆栈跟踪）：
请求处理期间的异常：
由 java.lang.IllegalStateException 与 消息：“没有阶段 id 绑定到当前 线程（确保你没有两个 SeamPhaseListener 实例 已安装）”
当“JBoss-izing”同一个 EAR（删除 JBoss 提供的休眠 jar，并将所有库从 EAR/lib 移动到 EAR 根目录）时，应用程序正确加载。应用程序和调试页面都正确显示。

【问题讨论】：
-
@Markos Fragkakis 您的 StackTrace 与您的调试页面无关。它的发生是因为它抱怨：No phase id bound to current thread （确保你没有安装两个 SeamPhaseListener 实例） 所以使用 WINRAR 提取所有的 ear 应用程序，并确保你的 war 文件WEB-INF/lib 文件夹和你的 ejb jar 文件 lib 文件夹不包含 jboss-seam.jar 它必须放在你的ear文件的根文件夹中并在ear中声明META-INF/application.xml 文件
-
@Arthur Ronald F D Garcia，这个问题毕竟可能与 Weblogic 有关。经过这些天，我已经改变了耳朵的结构。它在其根目录中包含所有 EJB（包括 Seam）。我的 .war 只包含它自己的库（Richfaces、Facelets、Seam UI、Seam Debug）。我在 JBoss 4.2.3.GA 上尝试了 .ear（在删除了 JBoss 中包含的 Hibernate 之后）并且它起作用了。
-
@Markos Fragkakis Bingo！问题是因为Weblogic。如前所述：Weblogic 服务器存在一些需要解决的已知问题，以及特定于 Weblogic 所需的配置更改。 仔细阅读 docs.jboss.org/seam/2.2.0.GA/reference/en-US/html/… 参见该页面 Weblogic EJB 支持的特殊 jboss-seam.jar
-
@Arthur Ronald F D Garcia，请检查上次更新（更新 3 ！！）我已经使用了 Weblogic 特定的 Seam，并且已经完成了您提供的链接中提到的所有必要更改。我开始怀疑 Weblogic 和调试页面存在错误。

@Markos Fragkakis 附加链接：download.oracle.com/docs/cd/E12840_01/wls/docs103/programming/… 和 download.oracle.com/docs/cd/E12840_01/wls/docs103/webapp/… 除此之外，我认为 APP-INF 和 APP-INF/classes 都不是目录JEE规范标准化所以，牢记在心
