Question

我正在将我的应用程序升级到primefaces 5.1和Mojarra javax.faces 2.1.29版本。在我使用JDK 1.7之前，我没有收到任何错误。为了与客户端环境兼容，我已经更改了weblogic JDK运行时和My Eclipse编译器来设置 JDK 1.6和我得到的错误。是否有人遇到过同样的问题？我需要使用较低版本吗？ Mojarra 2.1.28或2.1.27与JDK 1.6

Answer 1

真的很奇怪，但你是对的。这是JDK版本的问题。在我的情况下，我在Glassfish 3.1.2-11上使用JDK 1.6.0-30，JSF 2.1.29时遇到了同样的错误。

在您提出建议后，我将JDK更改为1.7.0-45，问题就消失了。

Mojarra 2.1.29与JDK 1.6不兼容
