我想在 netbeans 中部署axis2 web 服务，我在netbeans 中安装了插件axis2。我也使用 EclipseLink 2.0 连接数据库。当我在我创建的主类中使用时，我的连接成功。但是，当我尝试通过右键单击服务在 netbeans 中测试我的 Web 服务时，会抛出此异常：

我可以部署其他不包含与 eclipselink (entityManager...) 的连接的服务。
我在其他论坛中发现了同样的问题，但他们使用的是休眠，解决方案是添加到类路径中：hibernate-jpa-2.0-api-1.0.0.Final.jar，在这个链接http://www。 coderanch.com/t/513512/ORM/databases/Error-java-lang-NoClassDefFoundError-javax
但我不知道 EclipseLink 有什么问题我不知道我是否添加其他库以及在哪里.. 非常感谢...
这是我的服务班
公共类登录服务 {
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);
}
}
