我有一个SFSB声明:
@Stateful(name="StatefulBean")
public class StatefulBean implements MyListener
{
private String id;
public StatefulBean()
{
}
public void setId(String id)
{
this.id = id;
}
}
我试图在servlet的doGet方法中实例化它,如下所示:
protected void doGet(final HttpServletRequest request,
final HttpServletResponse response) throws ServletException, IOException
{
Date now = new Date();
String id = new Long(now.getTime()).toString();
try
{
Context context = new InitialContext();
StatefulBean statefulBean = (StatefulBean) context.lookup("name");
statefulBean.setId(id);
response.getWriter().write("Created StatefulBean with id " + id);
}
catch(Exception ex)
{
response.getWriter().write("Exception creating bean:" + ex.getMessage());
}
}
servlet和bean都属于my.package
,并且在同一个名为BeanTest.war的war文件中部署到Glassfish3服务器。
我在确定name
应该是什么时遇到问题。 Glassfish server.log声明:
[#|2014-05-20T16:31:51.720-0600|INFO|glassfish3.1.2|javax.enterprise.system.container.ejb.com.sun.ejb.containers|_ThreadID=988;_ThreadName=Thread-14;|EJB5181:Portable JNDI names for EJB StatefulBean: [java:global/BeanTest/StatefulBean!my.package.MyListener, java:global/BeanTest/StatefulBean]|#]
我尝试在name
和java:global/BeanTest/StatefulBean!ca.shaw.tno.oss.MyListener
的查询调用中设置java:global/BeanTest/StatefulBean
。当使用其中任何一个调用doGet时,我收到此错误:
Exception processing batch:com.sun.proxy.$Proxy353 cannot be cast to my.package.StatefulBean
由于这些是Glassfish服务器提供的唯一两个命名选项,我应该使用什么?
答案 0 :(得分:0)
问题是我没有使用@LocalBean注释我的StatefulBean。一旦我添加了它,JNDI查找就成功了。
@Stateful(name="StatefulBean")
@LocalBean
public class StatefulBean implements MyListener
{
private String id;
public StatefulBean()
{
}
public void setId(String id)
{
this.id = id;
}
}
