Hi,
I am looking for a JET2 sample, where the input is a live Java object --
which was described in JET1 tutorials published. I see that most of the
JET2 samples talk about a sample xml input and the template operates on
it using XPath.
Can someone please share some sample where input is a Java object?
Thanks in advance.

Anand:
If you are looking to manipulate Java objects directly, here are a few
suggestions.
1) To lauch a JET transformation, use
JET2Platform.runTransformationOnObject(), passing the object you want.
2) With-in a JET2 template, to access that object, use:
context.getSource().
(BTW, you can use Java scriptlets <% ...java statements ...%> and Java
expressions <%= expression %> within the template).
3) To write text from a scriptlet, use the 'out' variable.
If you can tell us a bit more about the context in which you want to use
JET, I can give you more hints.
Thanks,
Paul

Paul, thanks for your reply.
I writing out some C++ code, by walking (parts of) the CDT AST.
So the input to my template would be a IASTTranslationUnit or
IASTCompositeTypeSpecifier object.
Using JET1, I figured out that it was as simple as passing the argument
to the template, and then play with that in the template.
I wasn't exactly sure how to achieve the same using JET2.
Here's a snippet from JET1 that I have put together. An analogy/example
with JET2 to achieve the same, would be really nice.
<%@jet package="com.mypackage"
imports="org.eclipse.cdt.core.dom.ast.* java.util.*"
class="MyGenerator"
%>
<% IASTTranslationUnit translationUnit = (IASTTranslationUnit) argument; %>
<%= Do Something here from the TU passed %>
thanks again,
Anand

Anand:
Apart form context.getSource(), you can also set JET2 context variables:
context.setVariable("someName", someValue);
You can then get these inside your templates:
<%
IASTTranslationUnit translationUnit = (IASTTranslationUnit)
context.getVariable("someName");
%>
