【问题描述】：

我正在使用 openEJB 的 TomEE++ 运行企业 Java 应用程序。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，我遇到了一些奇怪的 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。

一开始，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

之类的行

INFO: OpenWebBeans Container is starting...

据我所知，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

之后，我发现一行表明 openejb 已启动

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：

【解决方案1】：

听起来更像是从 Eclipse 启动 Tomcat/TomEE 时不使用 JavaAgent。有一个openejb-javaagent jar文件需要在命令行中通过-javaagentvm参数指定。

这将打开 OpenJPA 字节码增强器并使所有 JPA 功能正常工作。如果没有-javaagent vm 标志，它将在某种程度上起作用，因为 OpenJPA 对实现 JPA 的基于子类的方法的支持有限（只有两种实现 JPA 的方法：子类化实体类或字节码增强实体类）。例如，Hibernate 仅使用子类化，并且不需要 javaagent。

普通的 Tomcat 启动命令将具有以下参数：

/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

一个 TomEE 安装将有一个额外的 -javaagent，因为 OpenJPA 需要它（如果使用 Hibernate 可以省略）。

/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
org.apache.catalina.startup.Bootstrap
start
