在tomcat服务的配置文件context.xml文件中加入如下代码 <Context> <Context>
<Context>
<Environment name="hao" value="hello hao" type="java.lang.String" />
</Context>

在jsp页面上写
<%

Context context = new InitialContext();

String ooString = (String)context.lookup("java:comp/env/tjndi");

out.println(ooString);

%>

会报一个 这样的错误
org.apache.jasper.JasperException: javax.servlet.ServletException: javax.naming.NameNotFoundException: Name tjndi is not bound in this Context
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:541)

org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:320)

javax.servlet.http.HttpServlet.service(HttpServlet.java:803)

Answer 1

String ooString = (String)context.lookup("java:comp/env/tjndi");
修改为：
String ooString = (String)context.lookup("java:comp/env/hao");
