标签 java eclipse jsf tomcat omnifaces

我正在尝试显示来自托管 bean 方法的图像，该方法返回 byte[]与 <o:graphicImage>使用 omnifaces 我在 WEB_INF/lib 中部署了 omnifaces 2.1 这是我的代码

注册.java

一开始tomcat启动显示这个错误<o:graphicImage> Tag Library supports namespace: http://omnifaces.org/ui, but no tag was defined for name: graphicImage]当我在 eclipse 中将 omnifaces.jar 添加到我的构建路径中时。 omnifaces.jar之后在WEB-INF/lib 它不让 tomcat 启动并显示以下错误

我使用的是 JSF 2.0(Apache Myfaces)，我还使用 tomahawk 1.1.14 来上传文件。

最佳答案

OmniFaces 2.x 需要 CDI .另见 Download节OmniFaces homepage :

OmniFaces 2.x

Required: Java 1.7, JSF 2.2, EL 2.2, Servlet 3.0 and CDI 1.1
Optional: BV 1.0

作为准系统 JSP/Servlet 容器的 Tomcat 不随 CDI 一起提供。它仅在成熟的 Java EE 容器中可用，如 WildFly和 TomEE .这同样适用于 JSF(和 JSTL)，顺便说一下，您必须在 Tomcat 中手动安装它。

您有 2 个选择:

  1. 用 TomEE 或任何其他 Java EE 容器替换 Tomcat。

  2. 在 Tomcat 中手动安装 CDI。

另见:
