OpenEJBのTomEE ++を使用して、エンタープライズJavaアプリケーションを実行しています。

私はopenEJBのTomEE ++を使用しています。このアプリはEclipse Helios内から開始されています。 EclipseでTomcatを担当できるように、「サーバーの場所」を変更しました。私が持っている「スライド」OpenEJBのTomEE ++を使用して、エンタープライズJavaアプリケーションを実行しています。

と呼ば

私はEclipse内からアプリケーションを起動すると、私は思っていますいくつかの奇妙なJPAのエラーは、OpenEJBのwebアプリは私のWebアプリケーションの後にロードされているという事実から来るかもしれない取得、 openejbが0の値を持つのに対し、web.xmlのwebappの起動時ロード値を20に変更しました。

コンソールの出力から、私はopenejbが私の前後で起動しているかどうかわかりません応用。ログは少し矛盾しているようです。

右初めに、私はOpenEJBのが起動しなかったことを示唆しているように思われ

ERROR: OpenEJB webapp was not found

を見ることができます。しかしその後すぐに、私はopenejbからの私の限られた知識から来るだろう

INFO: OpenWebBeans Container is starting...

のような行を見る。

その後、鉱山を含むいくつかのアプリの起動など、さまざまなことが起こります。その後

TomcatWebAppBuilder.start /slides

、私はOpenEJBのは、だから、

TomcatWebAppBuilder.start /openejb

を開始したことを示唆している行を見つけ、正確に何が起きているのですか？ openejbはアプリケーションの前後で起動していますか？以下のログ投稿

は、Tomcat/TomEEは、Eclipseのから開始されたときJavaAgentが使用されていない以上のような音。コマンドラインで-javaagent vmパラメータを使用して指定する必要があるopenejb-javaagent jarファイルがあります。

これにより、OpenJPAバイトコードエンハンサが有効になり、すべてのJPA機能が正しく機能します。 OpenJPAはJPAを実装するためのサブクラスベースのアプローチ（JPAを実装する2つの方法：サブクラス化エンティティクラスまたはバイトコードエンハンスメントエンティティクラス）のサポートが限られているため、vmフラグは-javaagentでなくても動作します。例えば、Hibernateはサブクラス化のみを使用し、javaagentは必要ありません。

AバニラTomcatの起動コマンドは、これらの引数を持っています：

/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は、1つの余分-javaagentを持つことになりますインストールOpenJPAのは、それを必要とする（代わりにHibernateを使用している場合は省略できます）。

/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin/java
