I am trying to get a String parameter "username" from the request with Expression Language. I've done some research, but couldn't find a way to do so, I would like something similar to ${pageContext.request.parameter.username}

How get a specific request parameter, using only expression language?

If get an attribute from 'session', try this ${username}.

If get an parameter from 'request', try this ${param.username}.

  • You question is actually about object scope in JSP. For your reference, check this out: http://docs.oracle.com/javaee/1.4/tutorial/doc/JSPIntro7.html – CE ZHANG Nov 05 '14 at 01:32

The syntax to get the attributes from session would be,

${sessionScope[name]}

And for the request attributes , you can use 

${param[name]}

  • For request attributes you should use quotes to wrap the parameter's name. ${param['name']} – Khaled Dec 08 '16 at 09:54
