To lendo a apostila da caelum fj28 sobre vraptor e me deparei com um problema:

o exemplo da loja de compras tem um a classe Carrinho, que deve ser anotada como @Component e @SessionScoped.

No CarrinhoController tudo beleza, mas na jsp, o acesso via ${carrinho} devolve null. Ele também da uma NotSerializableException no console do Tomcat pra um componente do PicoContainerRegistry, não sei se tem a ver.

Alura O que são algoritmos e lógica de programação e como aprender? Entenda o que são algoritmos e lógica de programação e qual é a importância desses conceitos para começar a programar

vc registrou o PicoProvider no web.xml? o pico não exporta os componentes SessionScoped, vc precisa usar o Spring ou o Guice pra isso funcionar sem problemas.

nope. na apostila nao fala nada disso. nem configurei web.xml

mas os jars que estão na pasta WEB-INF/lib, tem os jars do spring, do pico, ou do guice?

Estou com um problema de providers tb... acho que da pra aproveitar o tópico.

Coloquei o jar do pico dentro do web-inf/lib e retirei os do spring. 
<dependency org="br.com.caelum" name="vraptor" rev="3.3.1" conf="default">
	<exclude org="org.springframework" />
</dependency>
<dependency org="org.picocontainer" name="picocontainer" rev="2.8" conf="default" />

No desenvolvimento, funciona beleza. Mas quando subo pra produção (no gae) o seguinte erro acontece:

Repare que é depois que o vraptor startou.
O erro é de uma dependencia do spring.

Se for:

registrou o PicoProvider no web.xml?

Não registrei... como faço? não achei sobre. :(

usando o Google Guice ta tudo funcionado aqui, sem XML

cara, dá um clean aí no seu projeto, pq ele ainda tá referenciando o spring em algum lugar…

garante aí que não tem nenhum jar do spring no classpath.
