jsp - Does Websphere Commerce 7 support JSTL 1.1 XML in widgets? -

-

i have made new blank widget , added page. jstl tags work in jsp, trying example

<%@ taglib uri="http://java.sun.com/jsp/jstl/xml" prefix="x" %> <x:set var="test"/>

results in unresolvableexception

[19/11/14 17:16:45:617 fet] 0000001f logginghelper e /genericjsppageerror.jsp - $requestscope:ec_device                              org.apache.taglibs.standard.tag.common.xml.unresolvableexception: $requestscope:ec_device @ org.apache.taglibs.standard.tag.common.xml.xpathutil$jstlvariablecontext.notnull(xpathutil.java:377) @ org.apache.taglibs.standard.tag.common.xml.xpathutil$jstlvariablecontext.getvariablevalue(xpathutil.java:322) @ org.apache.taglibs.standard.tag.common.xml.xpathutil$jstlvariablecontext.getvariableorparam(xpathutil.java:241) @ org.apache.taglibs.standard.tag.common.xml.xpathutil.fillvarstack(xpathutil.java:792) @ org.apache.taglibs.standard.tag.common.xml.xpathutil.selectnodes(xpathutil.java:536) @ org.apache.taglibs.standard.tag.common.xml.settag.dostarttag(settag.java:69) ...

i have no idea ec_device , coming from. jstl xml tags not used anywhere else in project, cannot verify whether work @ all, , hence i'm asking.

jstl tags still valid, error elsewhere in code... maybe down new directory structure when widget uses existing resources?
