Hi,I want to use a sessionbean.

And my web.xml is below

<web-app>

<display-name>WEB APP</display-name>

<description>WEB APP description</description>

<servlet>

<servlet-name>aaa.jsp</servlet-name>

<jsp-file>/aaa.jsp</jsp-file>

</servlet>

<servlet-mapping>

<servlet-name>aaa.jsp</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

<ejb-ref>

<ejb-ref-name>ejb/SessioncccBean</ejb-ref-name>

<ejb-ref-type>Session</ejb-ref-type>

<home>zxcvboy.SessioncccHome</home>

<remote>zxcvboy.Sessionccc</remote>

<ejb-link>SessioncccBean</ejb-link>

</ejb-ref>

</web-app>

My sorce is

Object ob = ctx.lookup("java:comp/env/ejb/SessioncccBean");

Is there something wrong?
