<jsp:param name="username" value="<%=request.getParameter("username")%>"/>
<jsp:param name="age" value="<%=request.getParameter("age")%>"/>
<jsp:param name="msn" value="<%=request.getparameter("msn")%>"/>
这三个属性,如果没有导如这个页面的时候就会出错,因为request.getParameter("属性名称")的值为空

这里问题只可能是child2.jsp这个PAGE你根本就没建. 因为Apache Jasper无法找到child2.jsp, 所以跟本就不能COMPILE.
如果是PARAMETER有NULL的话, 一定是NullPointerException,如果其他的问题出现, 都必然是RuntimeException的子Exception.
