Omnifaces exception on deployment on Tomcat 7

问题


I'm trying to add Omnifaces 2.1 to a web application to use FullAjaxExceptionHandler and possibly other functionality in Omnifaces 2.1.

I've read and followed following post by BallusC and am still stuck: How to install and use CDI on Tomcat?

Tried to install Weld 2.2.9.Final and configure as described above. I am using the following:

JSF 2.2, EL 2.2, Servlet 3, Java 7

web.xml:

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="{name}" version="3.0">

Upon startup I am still getting the following exception:

The jar does indeed exist and has been added to the application.

What else could be causing this error?


回答1:


Ok issue is now resolved. I can confirm the following for Apache Tomcat/7.0.56:

  • /META-INF/context.xml is not required however the resource entry is still required. To resolve the issue I added the resource entry in the following existing location: tomcat\conf\Catalina\localhost{resource-file-name}.xml

After that no errors appeared.

  • No related listeners need to be registered in web.xml
  • No related <resource-env-ref> are required in web.xml
  • /WEB-INF/beans.xml (empty) is required

Most of the above is covered here: http://balusc.blogspot.com.au/2013/10/how-to-install-cdi-in-tomcat.html

I wanted to provide an update to this though as some may find the resource loading part on tomcat helpful.

Thanks again BallusC. I've up-voted a similar post because the suggestion related to it helped me resolve this issue.
