Incompatibility between STRUTS TAGS and JSTL TAGS
Hello everybody. I have a small problem that maybe someone has already
had in the past.
In a jsp page I try to retrive request parameters thus ( STRUTS +
Jakarta TAGLIBS ) :
<req:parameters id="loop">
Name: <bean:write name="loop" property="name"/>
Value: <bean:write name="loop" property="value"/>
</req:parameters>
and this works fine...
When I try JSTL
<c:out value="${requestScope.source}"/>
<c:out value="${requestScope.animalId}"/>
<c:out value="${requestScope.injId}"/>
doesn't work...
The names of the the request parameters that should be there are correct...
Is there any masking between JSTL vars and STRUTS vars that someone is
aware of?
Todor

The above code looks for *attributes* in request scope,
not parameters. To access parameters via JSTL, you
have to make use of the implicit EL variable (actually
a java.util.Map) named 'param', like this:
<c:out value="${param.source}"/>
<c:out value="${param.animalId}"/>
<c:out value="${param.injId}"/>
HTH,

You seem to be confusing request parameters and request attributes (or
request-scoped variables). Try:
<c:out value="${param.source}"/>
JSTL gives you two ways (implicit objects) to get at request parameters:
param
a Map that maps parameter names to a single String parameter value (obtained by
calling ServletRequest.getParameter(String name))
paramValues
a Map that maps parameter names to a String[] of all values for that parameter
(obtained by calling ServletRequest.getParameterValues(String name))
