web配置servlet

web.xml:

<servlet>
<servlet-name>CdnContractServlet</servlet-name>
<servlet-class>com.dnion.dayu.jasper.CdnContractServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>CdnContractServlet</servlet-name>
<url-pattern>/cdncontract</url-pattern>
</servlet-mapping>

 

调用方式：

Session session = Sessions.getCurrent();
session.setAttribute("cdncontract_id", contract_id.getValue());
session.setAttribute("cdnflowname", flowname.getValue());
Executions.sendRedirect("/cdncontract");
