在TomEE中使用Weld CDI代替OpenWebBeans

Question

我想使用Mojarra和Weld在Apache TomEE上运行一个WebApp。

是否因为TomEE已经使用了另一个CDI-Framework（OpenWebB）而出现了问题？有可能让TomEE和Weld一起运行吗？

Answer 1

你绝对可以让TomEE使用Mojarra而不是MyFaces。但是，由于集成CDI实现的复杂性，使用Weld而不是OpenWebBeans是不可能的。

对于使用Mojarra，只需在物理上删除 /lib/myfaces-*.jar 文件，并将Mojarra impl和api jar放在其中。
