[RESOLVIDO]Servlet acessando methodos da Business?

Assuntos Gerais
#1

Olá estou com uma dúvida muito básica ao meu ver!
Tenho um servlet que é chamada pelo FLEX ,
e ela tem ki fazer uma busca no banco de dados…

Não estou sabendo como fazer essa declaração da BUsiness ou da DAO?

@Autowired
private IProUnidadeBusiness unidadeBusiness;

dessa maneira retorno NULL.

Alguém poderia me ajudar?
grato…

Ta usando spring pra injetar essa dependencia??? Se tiver, posta teu AplicationContext.xml…

Boa tarde

Pelo que estou vendo você esta usando Spring para realizar a injeção, você precisa que a instância da Servlet seja vista também pelo contexto do Spring, para que assim ele possa realizar a injeção das dependências, uma forma de fazer isso é colocar no método init da servlet um método que faça com que o Spring tenha acesso a Servlet.

Tente assim:

SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);

Até mais.
