我正在运行一个企业 Java 应用程序，使用 openEJB 的 TomEE++。该应用程序是从 Eclipse Helios 中启动的。我已经更改了 Eclipse 中的“服务器位置”，以允许 Eclipse 负责 Tomcat。

当我从 Eclipse 中启动应用程序时，我得到了一些奇怪的 JPA 错误，我认为这可能是因为 openejb webapp 是在我的 webapp 之后加载的，称为“幻灯片”

我已将 web.xml 中 webapp 的 load-on-startup 值更改为 20，而 openejb 的值为 0。

从控制台的输出中，我无法确定 openejb 是在我的应用程序之前还是之后启动。日志似乎有点矛盾。

刚开始，我可以看到

ERROR: OpenEJB webapp was not found

这似乎表明 openejb 没有启动。但不久之后，我看到了诸如

INFO: OpenWebBeans Container is starting...

在我有限的知识中，这将来自 openejb。

在那之后发生了很多事情，包括几个应用程序的启动，包括我的。

TomcatWebAppBuilder.start /slides

在那之后，我发现一行表明 openejb 已经启动

TomcatWebAppBuilder.start /openejb

那么，到底发生了什么？openejb 是在我的申请之前还是之后启动？

在下面发布日志：

Sounds more like the JavaAgent isn't used when Tomcat/TomEE is started from Eclipse. There's an openejb-javaagent jar file that need to specified on the command line via the -javaagent vm parameter.

This turns on the OpenJPA bytecode enhancer and makes all the JPA functionality work properly. It will work somewhat without the -javaagent vm flag as OpenJPA has limited support for the subclass-based approach to implementing JPA (only two ways to implement JPA: subclassing entity classes or bytecode enhancing entity classes). Hibernate uses only subclassing, for example, and doesn't need a javaagent.

A vanilla Tomcat startup command will have these arguments:

/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin/java
-Djava.util.logging.config.file=<tomcat-home>/conf/logging.properties
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.endorsed.dirs=<tomcat-home>/endorsed
-classpath <tomcat-home>/bin/bootstrap.jar:<tomcat-home>/bin/tomcat-juli.jar
-Dcatalina.base=<tomcat-home>
-Dcatalina.home=<tomcat-home>
-Djava.io.tmpdir=<tomcat-home>/temp
org.apache.catalina.startup.Bootstrap
start

A TomEE install will have one extra -javaagent as OpenJPA requires it (can be omitted if using Hibernate instead).

/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin/java
-Djava.util.logging.config.file=<tomcat-home>/conf/logging.properties
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.endorsed.dirs=<tomcat-home>/endorsed
-classpath <tomcat-home>/bin/bootstrap.jar:<tomcat-home>/bin/tomcat-juli.jar
-Dcatalina.base=<tomcat-home>
-Dcatalina.home=<tomcat-home>
-Djava.io.tmpdir=<tomcat-home>/temp
-javaagent:<tomcat-home>/lib/openejb-javaagent.jar
