[RESOLVIDO]Erro prepareStatement Data Source Weblogic

Front-end
#1

Pessoal. Estou com o meu DataSource no Weblogic 10.3 com conexão ao Oracle 9.

Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY,
       	         "weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL, "t3://localhost:7001");
InitialContext initialContext = new InitialContext(ht);
DataSource ds = (DataSource) initialContext.lookup("jdbc/DS");
Connection c = ds.getConnection();

Até aqui tudo bem.
Mas quanto executo o prepareStatement


PreparedStatement st = c.prepareStatement("SELECT * FROM DDD");

Não retorna valor a Statement e retorna a exception.

[/code]

Realizando com a Classe Statement funciona.

Statement st = c.createStatement();
ResultSet rs = st.executeQuery("Select * from DDD");

Alguem tem alguma ideia para ajudar?
Obrigado

Fui verificando o erro e o que a IDE me informava. Na verdade erá a falta da Classe WrapperFactory do Weblogic.
Que esta dentro do Arquivo weblogic.jar
que ficar WLHOME/Server/LIB
