java - 如何反向移植 6.1.1 jsf portlet 以使其在 6.1.0 liferay 门户上运行？

Question

我正在尝试让 6.1.1 Portlet 在 6.1.0 Liferay CE Portal 上运行。 JSF Portlet 使用 Liferay 的 ServiceBuilder 和许多其他 Util API 类。

我认为最好的想法是使用正确的 liferay-plugins-sdk 重新编译 portlet。 下载6.1.0 SDK后，将其替换到eclipse项目中，并重建它，我得到 有几个异常(exception)。它们在启动服务器后立即发生。

有人有好主意吗？我也在官方论坛上发布了这个问题，但也许在这里我接触到了更多的人......

====更新1====

为了解决上述异常，我再次在 6.1.0 portlet 中运行服务构建器。

现在可以使用 portlet buuut 启动服务器 该 portlet 在门户中不可见/不可用，无法添加到页面中，我得到了 以下ClassNotFoundException:PortletBeanLocatorUtil:

在 6.1.0 sdk 中重新编译 portlet 可能会更容易。特别是当您使用 ServiceBuilder 时:您正在使用一个代码生成器运行，该生成器可能依赖于将运行时与生成的代码相匹配的运行时文件。

对于纯 JSR-286 portlet，它们甚至可以跨主要版本轻松兼容。如果您使用更复杂的代码，例如ServiceBuilder 或 API，我们付出了很多努力来保持其兼容，但不能保证它实际上是二进制兼容的 - 抱歉，这就是生活。

对于 Liferay 自己的插件，您需要使用匹配的版本 - 它们在更新之间不会进行测试。他们很可能也使用 ServiceBuilder 和 API。
