There is a way to accomplish both, it appears that in order to pass it
along more than one grammar file, then you must pass it an array, and
not some type of deliminated list. Also, if in the case of having one
or more of them of the type dtmf, you need to pass an array of
org.apache.taglibs.rdc.core.Grammar objects.
Since the information necessary to create these objects lives in the
jsp context of my application, I have to resort to scriptlets to
accomplish the above. I would much rather see a method for
rdc:template to handle this on it's own.
I recommend:
1. Making rdctemplate.java look for and handle a comma seperated list
of grammar url's
2. possible adding another attribute to template:
<rdc:template grammar="foo.grxml,bar.grxml" grammar-dtmf="dtmf.grxml"/>
Then, the code could loadall of them into the document. Any other
ideas on how to accomplish this easily, without resorting to
scriptlets?
Here is what I have now:
<c:set var="gramUrl1">${grammarRoot}subid.grxml</c:set>
<c:set var="gramUrl2">${grammarRoot}subid-dtmf.grxml</c:set>
<%
String gramUrl1= (String) pageContext.getAttribute("gramUrl1");
String gramUrl2= (String) pageContext.getAttribute("gramUrl2");
org.apache.taglibs.rdc.core.Grammar gram1 = new
org.apache.taglibs.rdc.core.Grammar(gramUrl1, Boolean.FALSE,
Boolean.FALSE,"subid");
org.apache.taglibs.rdc.core.Grammar gram2 = new
org.apache.taglibs.rdc.core.Grammar(gramUrl2, Boolean.TRUE,
Boolean.FALSE,"subid-dtmf");
org.apache.taglibs.rdc.core.Grammar [] arrayGrams = new
org.apache.taglibs.rdc.core.Grammar [] {gram1,gram2};
%>
<rdc:template id="memberId" config="${configRoot}${form.rdcConfigFile}"
confirm="false" grammar="<%=arrayGrams %>"
minConfidence="0.42" numNBest="1" />
ugly.
