Weblogic启动报ServletException的问题

weblogic部署项目时报错：

<2019-1-13 下午06时37分20秒 CST> <Error> <HTTP> <BEA-101216> <Servlet: "initServlet" failed to preload on startup in Web application: "1web.war".
javax.servlet.ServletException
        at com.amerisia.ebills.commons.web.InitServlet.getEJB(InitServlet.java:643)
        at com.amerisia.ebills.commons.web.InitServlet.initWorklist(InitServlet.java:157)
        at com.amerisia.ebills.commons.web.InitServlet.init(InitServlet.java:55)

        at weblogic.servlet.internal.StubSecurityHelper$ServletInitAction.run(StubSecurityHelper.java:283)
        Truncated. see log file for complete stacktrace

web.xml部分配置：

<servlet>
        <servlet-name>initServlet</servlet-name>
        <servlet-class>com.amerisia.ebills.commons.web.InitServlet</servlet-class>
        <init-param>
            <param-name>debug</param-name>
            <param-value>2</param-value>
        </init-param>
        <load-on-startup>0</load-on-startup>
    </servlet>

报错原因是关于Weblogic的参数配置问题，有涉及到weblogic登陆的用户名/密码参数配置的地方一定要配置好。
