Good morning,
I need some help for JET. I would like to use a method defined in my jet
file and use dynamic parameter when I call it. how can I do that? is it
possible?
eg:
<%!
public String getType(String t) {
if (t.compareTo("s")==0){
return "String";
}
return "To define";
}
%>
<%= getType( [Dynamic value] ) %>
something like that
<%= getType(<c:get select="$p/@type" />)%> is it possible? or how can I do
something like that?
Thanks in advance,
Thomas

No,
<%= getType(<c:get select="$p/@type" />)%>
is not valid syntax.
However, the JET context and XPath engine are available to you in Java code.
I'd recommend a class like the following:
import org.eclipse.jet.XPathContextExtender;
public class DoXPath {
public static String get(JET2Context context, String xpath) {
XPathContextExtender xpe =
XPathContextExtender.getInstance(context);
return xpe.resolveAsString(xpe.currentXPathContextObject(), xpath);
}
}
Depending on where you place DoXPath, you may have to add a
<%@jet imports="....DoXPath" %>
to your template.
Then, your Java expression becomes:
<%= getType(DoXPath.get(context, "$p/@type")) %>
