Session attribute referenced within struts:message tag

[Stephen Earl <se...@smartpoint.com>]

Hi,

Can anyone tell me how get the following strugs tag to work?

<struts:message key="labels.forms.userType.<%=
session.getAttribute("userType") %>" />

In this case I have an ApplicationResources. properties file containing the
following entries:

labels.forms.userType.1=Administrative User
labels.forms.userType.2=Guest User
etc...

I don't want to do an if-then to determine what key to pass... I need to
generate the key string and pass it to the struts:message tag.

Am I missing something basic here?

Thanks in advance, 

Stephen Earl

It is not legal JSP syntax to mix a constant string and a runtime
expression
like this.  To accomplish what you want, try the following:

    <struts:message key='<%= "labels.forms.userType." +
      session.getAttribute("userType") %>'/>

Note the use of single quotes around the value for the "key" attribute,
so that you don't have to escape the double quotes used within the Java
expression.
