JSF - Erro na Injeção do Recurso

Front-end
#1

Boa noite a todos,
Estou com um problema ao trabalhar com injeção de dependência no JSF. Já procurei, mas nunca encontro soluções para problemas semelhantes ao meu.
Estou trabalhando com JSF 2.0, Primefaces, JPA , Tomcat 7, Mysql

O erro que eu estou recebendo ao chamar /RMX/servico.jsf é :

exception

javax.servlet.ServletException: Um erro ocorreu ao realizar a injeção de recurso no bean gerenciado ServicoBean
	javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)
root cause

com.sun.faces.mgbean.ManagedBeanCreationException: Um erro ocorreu ao realizar a injeção de recurso no bean gerenciado ServicoBean
	com.sun.faces.mgbean.BeanBuilder.invokePostConstruct(BeanBuilder.java:229)

Oi Bom dia Eu olhei seu código o seu controlador ServicoBean na anotation "@ManagedBean(name=“ServicoBean”) "
ta maiúsculo na verdade e pra ta assim @ManagedBean(name=“servicoBean”) pode ser esse o problema…
