I can deploy others services that not contain connections with eclipselink (entityManager...)..
I found in others forum with the same problem but they're using hibernate, that the solution is add to classpath this: hibernate-jpa-2.0-api-1.0.0.Final.jar, in this link http://www.coderanch.com/t/513512/ORM/databases/Error-java-lang-NoClassDefFoundError-javax
But I dont Know what is the problem with EclipseLink i dont know if i add other library and where.. thank you very much...
This my service class
public class LoginService {
EntityManagerFactory emf = ManageConnection.
getStatsEntityManagerFactory(PersistenceConfiguration.
getPERSISTENCE_UNIT_NAME());
public String prubaServicioWeb(String nombre) {
return nombre + " Welcome";
}
public void loginService(String whatever) {
BankJpaController bankController = new
BankJpaController(emf);
Bank bank = new Bank();
bank.setId(null);
bank.setBankCode("BNSJ");
bank.setName("Bank of America");
bankController.create(bank);
}
}

You need the javax.persistence classes that come in either the javax.persistence_1.0.0.jar (if using only JPA 1.0) or javax.persistence_2.0.4.v201112161009.jar if using JPA 2.0 (the jar might be named slightly different, this was what was shipped with a 2.4 milestone).
These will be in the jlib/jpa directory of your EclipseLink download.
