Spring MVC 3.0.0 App não Bootstrap no WebLogic Server 11Gr1 - ClassCastException

Question

Eu tenho um aplicativo baseado em MVC de primavera (3.0.0.Release), preciso implantar no Oracle WebLogic Server 11gr1. Funciona bem no Spring TC Server. Quando implanto meu arquivo de guerra de aplicativos (via STS/Eclipse "Servidores" Visualização ou para a pasta "auto-implantação" ou manualmente através do administrador da web), recebo a seguinte exceção:

    <Feb 3, 2010 9:17:20 AM GMT> <Error> <org.springframework.web.context.ContextLoader> <BEA-000000> <Context initialization failed

Agora isso é depois que eu já descobri a necessidade de definir:

<wls:prefer-web-inf-classes>true</wls:prefer-web-inf-classes>

Em WebLogic.xml (que corrigiu minha infinidade de problemas anteriores - o caminho da classe estava totalmente ferrado e eu estava recebendo problemas "noschmethoderror" para o "getbeandefinitiondefaults de primavera (...) que foi incluído no diretório web -inf/lib da minha guerra).

A investigação mostrou que javax.xml.parsers.DocumentBuilderFactory Vem de XML-Apis-1.0.b2.jar, que está sendo trazido por Maven de Commons-Digester, Dom4J e Jdom. Em suma, preciso que o meu aplicativo de primavera seja executado.

Eu verifiquei (e verifiquei duas vezes) e sou não Bundling da aula WebLogic com minha guerra, então não estou me atirando no meu próprio pé.

Eu também vi este post nos fóruns Java.net: http://forums.java.net/jive/thread.jspa?messageId=216363 - A solução alternativa LOG4J não funcionou (presumo porque a raiz do problema não é log4j) e esse bug corrige nota no oracle.com (pesquise "CR172469") http://download-llnw.oracle.com/docs/cd/e13222_01/wls/docs81/notes/resolved_sp03.html Isso parece não fazer nada.

O que eu não entendo é que estou dizendo ao WebLogic para preferir os potes na minha web-inf/lib, o frasco que eu preciso está lá, e o erro vem da primavera, não weblogic (ou seja, não estou forçando o próprio servidor para usar um frasco que não pode lidar.)

Eu adiei de adicionar mais da minha configuração de primavera a esta pergunta, pois não tenho certeza de que é relevante. Se, no entanto, isso ajudaria, entre em contato e eu vou adicioná -lo.

Espero que alguém possa ajudar.

Regs, Andrew

Answer 1

Seu aplicativo quase certamente não deve incluir nenhum javax.* Classes dentro de si - elas geralmente são tratadas pelo AppServer. Se você fizer isso, você acaba com ClassCastExceptions bem assim.

Você precisa impedir que Maven se arraste em coisas como xml-apis-1.0.b2.jar, não pertence dentro do seu aplicativo.

Se você corrigir isso, não precisará se preocupar com as configurações de clágica específica do WebLogic.
