grails 1.1.1 将支持 java 1.7

Question

目前我的应用程序在 grails 1.1.1 上运行，在 web sphere 服务器上运行 java 1.6。我的应用程序正在使用 java 1.6 的旧服务器上工作。最近服务器团队升级了 websphere 服务器 8.5.5，他们要求我们使用 java 1.7 部署一个耳朵。我已经用 java 1.7 部署了 ear。现在我遇到以下错误：

Error Page Exception
SRVE0260E: The server cannot use the error page specified for your application to handle the Original Exception printed below.

我有几个问题：

• Grails 1.1.1 将支持 java 1.7 吗？
• 如果不需要，我是否需要升级 grails？
• 升级 grails 的所有步骤是什么？
• web sphere 8.5.5 将不支持 java 1.6？
• 要解决此错误，我需要检查什么？
• 我需要更新 jars 吗？

请在下面找到我在我的应用程序中使用的罐子：

jar files

Answer 1

我会尽可能多地回答，但这是尽力而为，因为你在一篇帖子中问了太多问题！

1 - 可能不会。 Grails 1.1.1 于 2009 年问世，Java 1.7 于 2011 年问世，是对 1.6 的重大改变。您也许可以强迫他们一起工作，但六（多）年后您将很难找到好的信息。

2 - 是的。

3 - 您可以从这里开始：http://docs.grails.org/1.2.0/ 然后从那里开始。

4 - 请参阅下面的评论。 （本来我说的是错的：IBM 推荐 Java 8 和 WebSphere 8。）

5 - 可能并不重要，如果您要升级所有内容。

6 - 是的。
