- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我是 Java 的新手,我开发了一个示例 Java EE 应用程序,它可以与普通 Java 客户端一起使用,但不能与 Servlet 一起使用。我使用应用程序客户端、EJB 模块和 Web 模块在 Netbeans IDE 中开发了 EE 项目。
Customer.java
@Entity
@Table(name = "customer")
public class Customer implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column (name="id")
private String id;
@Column (name="name")
private String name;
public void setName(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
myBeanInterface.java
import Entities.Customer;
import javax.ejb.Remote;
@Remote
public interface myBeanInterface {
void addCustomer(Customer customer);
}
CustomerSession.java
@Stateless
public class CustomerSession implements myBeanInterface {
@PersistenceContext(unitName = "Omazon-EJBPU")
EntityManager em;
@Override
public void addCustomer(Customer customer)
{
em.persist(customer);
}
Java 客户端
@EJB
private static myBeanInterface inter;
public static void main(String[] args) throws NamingException {
InitialContext context = new InitialContext();
inter = (myBeanInterface) context.lookup("Session.myBeanInterface");
Customer customer = new Customer();
customer.setId("16906");
customer.setName("My book from Main");
inter.addCustomer(customer);
}
小服务程序
public class addCustomerServlet extends HttpServlet {
@EJB
public myBeanInterface myBean;
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException , NamingException {
InitialContext context = new InitialContext();
myBean = (myBeanInterface) context.lookup("Session.myBeanInterface");
Customer customer = new Customer();
customer.setId("1198");
customer.setName("i1787");
myBean.addCustomer(customer);
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
/* TODO output your page here. You may use following sample code. */
out.println("<!DOCTYPE html>");
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet addCustomerServlet</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Servlet addCustomerServlet at " + request.getContextPath() + "</h1>");
out.println("</body>");
out.println("</html>");
}
}

最佳答案
我通过在某个论坛上找到一个帖子解决了这个问题:
禁用 GlassFish Server v2 供应商特定的 JNDI 名称
GlassFish Server 3.1 支持的 EJB 3.1 规范定义了可移植的 EJB JNDI 名称。因此,不再需要继续使用旧的特定于供应商的 JNDI 名称。
默认情况下,GlassFish Server v2 特定的 JNDI 名称由 GlassFish Server 3.1 自动应用以实现向后兼容性。但是,这可能会导致一些易用性问题。例如,部署两个包含公开相同远程接口(interface)的远程 EJB 组件的不同应用程序导致默认 JNDI 名称之间发生冲突。
GlassFish Server 3.1 中对特定于 v2 的 JNDI 名称的默认处理可以使用 asadmin 命令或使用 disable-nonportable-jndi-names bool 属性进行管理glassfish-ejb-jar.xml 中的 ejb-container 元素。
使用asadmin 命令或直接修改glassfish-ejb-jar.xml 文件来设置disable-nonportable-jndi-names 属性。
使用asadmin命令:
asadmin> 设置 server.ejb-container.property.disable-nonportable-jndi-names="true"
直接修改glassfish-ejb-jar.xml文件。
将 disable-nonportable-jndi-names 属性添加到 glassfish-ejb-jar.xml 中的 ejb-container 元素。根据需要设置 disable-nonportable-jndi-names bool 值。false — 允许自动使用特定于 GlassFish Server v2 的 JNDI 名称。这是默认设置。
true — 禁止自动使用特定于 v2 的 JNDI 名称。在所有情况下,将使用 3.1 兼容的 JNDI 名称。
保存 glassfish-ejb-jar.xml 文件并重新启动 GlassFish Server 域。此设置适用于部署到服务器的所有 EJB。
