SOAPMessage + JAXB

Programação Java
#1

Ola pessoal,

Estou criando um cliente para acessar um webservice. Uso a IDE Netbeans com Java 6. Preciso fazer uma chamada que necessita adicionar um elemento no header da mensagem SOAP. Quando eu executo o método EfetuaLogin (mostrado no código abaixo) é gerado um erro que está descrito abaixo do código.

Eu usei o JAXB-xjc para gerar as classes de serialização dos métodos do webservice.
SDK\bin\xjc.bat -d “C:\XXX” -wsdl http://www.cvm.gov.br/webservices/Sistemas/SCW/CDocs/WsDownloadInfs.asmx?WSDL

Eu sou iniciante no mundo java. Pra falar a verdade é o meu primeiro projeto. Gostaria de saber se alguém sabe o porque do erro?

Eu já mandei a mensagem via telnet e o retorno foi o esperado, mas quando uso o método call da conexão dá o erro.

desde já agradeço.

    conexao.call(mensagem, u);
    conexao.close();
