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?

Re: Incompatibility between STRUTS TAGS and JSTL TAGS
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))

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}/
