jsf - java.lang.NoClassDefFoundError: Could not initialize class org.omnifaces.config.WebXml -

i have added added omnifaces 1.4.1 pom use of converters.

 <dependency>     <groupid>org.omnifaces</groupid>     <artifactid>omnifaces</artifactid>     <version>1.4.1</version> </dependency> 

now, every request application throws exception starts @

java.lang.noclassdeffounderror: not initialize class org.omnifaces.config.webxml 

the omnifaces.selectitemsindexconverter i'm using working fine, exception being thrown every request; on pages not contain onmifaces components.

my environment follows:

• tomcat 7.0.37
• mojarra 2.1.10
• primefaces 3.4.2
• primefaces extensions 0.6.1

is there additional setup required more adding pom?

java.lang.noclassdeffounderror: not initialize class org.omnifaces.config.webxml

this occur when the webxml configuration enum failed parse webapp's web.xml and/or web-fragment.xml(s) during initialization. should have thrown runtime exception that. check why it's been swallowed. it's perhaps tomcat specific.

as runtime exception being thrown in particular case,

java.lang.classnotfoundexception: avax.faces.application.viewexpiredexception

this suggests you've in web.xml like:

<error-page>     <exception-type>avax.faces.application.viewexpiredexception</exception-type>     ... </error-page> 

while should have been javax.faces.application.viewexpiredexception. fix accordingly , webxml succeed in parsing web.xml.
