JSP gets the session value problem from the action there are several ways:

For example, I have a session in action ("SessionID", "11111111")

First, use the struts tag to obtain: <s:property value= "#session. SessionID"/>

Second, <%=request.getsession.getattribute ("SessionID");> session is also one of the built-in objects, you can use the session directly, more convenient than the Request.getsession
It can also be written as <%=session.getattribute ("SessionID");>

III. EL expression get: ${sessionscope.sessionid}

If the value is a bean, it is the same, similar to ${sessionscope.bean.beansth}
