You need a useBean element to define "cmd" as the name of an actual Java object.

Try including isELIgnored= "false" in the page directive.

The <jsp:useBean> is not necessary if the scoped variable cmd has already been established on the request by a controller. Is that the case?

Actually, if you are seeing ${cmd}, including the delimiters, on the browser, it more likely means that the EL is not enabled, probably due to a misconfiguration of your application. See the JSP FAQ for information on properly configuring you web application.

No, that's a band-aid. The real fix is to configure the web app correctly eliminating the need for goop on all the pages.

You have to set the <el-ignored> tag in DD to configure for the entire application.

Yeah, but you don't want to put that on every page.

The most likely culprit is your deployment descriptor. Is it defined using the Servlet 2.3 DTD? If so, that will disable the EL!

See the JSP FAQ for the proper way to set up the web.xml.
