使用Eclipse GPE添加GWT Breaks Cloud SQL JPA

时间：2012-06-13 17:34:44

标签： gwt eclipse-plugin jpa-2.0 google-apps google-cloud-sql

我已经多次测试了Google Plugin for Eclipse（GPE）展示的一些奇怪的行为，这些行为同时运行了一个持久存在Google Cloud SQL和GWT的JPA方面。我正在使用Eclipse 3.7 Indigo，AppEngine 1.6.5，EclipseLink 2.3 JPA和GWT 2.4.0。

我在directions之后使用GPE成功设置了JPA 2.0。然后，一旦它工作，我然后尝试检查项目的GPE“Google”菜单中的“使用GWT”。在那一点上，JPA对Google Cloud SQL的持久性打破了。幸运的是，取消选中“使用GWT”是可逆的。我正在使用Cloud SQL进行开发，而不是使用本地MySQL。我想测试下一步。

这是我检查“使用GWT”后弹出的连接错误的堆栈跟踪。缺点是：“java.lang.NoClassDefFoundError：无法初始化类sun.security.pkcs11.SunPKCS11”。

这是我在Eclipse运行配置中的连接参数，在添加GWT之后：

    -remoteUI "${gwt_remote_ui_server_port}:${unique_id}" -logLevel INFO -codeServerPort 9997 -war /home/eric/workspace/jpatest/war -server com.google.appengine.tools.development.gwt.AppEngineLauncher -port 8888 com.myproject.jpatest
Just JPA: --port=8888 /home/eric/workspace/jpatest/war

提前感谢任何见解。我也会尝试与谷歌分享这个，因为我认为这是他们最终需要注意的事情。

我终于让它上班了。我真的不确定什么是最终解决方案，但确保我的驱动程序在Eclipse的数据库开发视角中都很好地连接，确保我的persistence.xml没有从原来的更改（下面），删除任何IDE投诉/错误/警告，并确保我的持久性单位被正确定义了诀窍。很多活动部件......感谢鼓励和想法，jonasr！
