[RESOLVIDO]Struts 2 - JSON - Plugin - Erro: ClassNotFoundException:org.apache.commons.lang.xwor

Front-end
#1

Boa tarde pessoal

Estou tentando uma tela na qual tem um combo com opções e uma tabela na qual estas opções vão sendo inseridas conforme o usuário vai escolhendo. Eu queria pegar esta coleção (representada pela tabela) para preencher um array list. Daí tive a brilhante idéia de usar o plugin do json para o struts (struts2-json-plugin). A idéia parecia boa, até que deu esta exceção:

27/11/2012 17:48:44 org.apache.catalina.core.StandardWrapperValve invoke

Boa noite pessoal,

O meu problema foi resolvido, era só a versão do plugin do JSON que não era a mesma do struts. Obs: Alguém poderia me indicar como posso fazer para ler o objeto JSON no JavaScript ou JQuery (Sim… Pareço realmente aquelas crianças que lutam para ganhar um brinquedo e depois não sabem o que fazer com ele :stuck_out_tongue: )

Inté…
