I took a bit of your script and this is how you can make it. Hopefully I'm good enough to explain so you understand how to use it.

<?xml version="1.0" encoding="utf-8" ?>

<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">

<g:evaluate var="jvar_gr" object="true">

var gr = new GlideRecord("sys_user");

gr.addQuery('sys_id',gs.getUserID());

gr.query();

gr;

</g:evaluate>

<j:while test="${jvar_gr.next()}">

dear ${jvar_gr.getValue('email')}

</j:while>

</j:jelly>

I learned my first jelly things while looking at the TechNows jelly episodes. You can find the first one here: TechNow Episode 1 | ServiceNow Jelly Scripting Part 1 of 3 - YouTube

If you want to use jelly variables you need 2 things.

1. Put jelly="true" in the evaluate like this:

<g:evaluate jelly="true">

2. when you refer to a jelly variable in the evaluate you need to put jelly. before the variable name like this:

var users_email = jelly.jvar_this_is_the_jelly_variablename

if you got any other questions, feel free to ask

Hi Akhil

As explained at point 7.2 in the wiki (Extensions to Jelly Syntax - ServiceNow Wiki ) you need to use the attribute jelly = true.

Try and let me know if this works.

<g:evaluate var="value" object="true" jelly="true">

var value = new GlideRecord("sys_user");

value.addQuery('sys_id',gs.getUserID());

value.query();

value;

</g:evaluate>

<j:while test="${value.next()}" >

Email is :${value.getValue('email')};

<g:evaluate var="user" object="true" jelly="true">

var mail = jelly.value.getValue('email');

var user = new GlideRecord('x_eyfso_it_capabil_itca_user');;

user.addQuery('respondent_email_id', mail);

user.query();

user;

</g:evaluate>

<j:while test="${user.next()}">

Dear ${user.getValue('respondent_name')};

</j:while>

It worked I have modified the script before , anyhow thanks for your reply

is there any documentation other than wiki available to learn more about jelly scripting?

You code above give some strange vibs there Ivano,

* You should only use jelly="true" if you are using jelly variables instead a <g:evaluate>. so in your first evaluate there is no reason for it.

* In your second <g:evaluate> you are calling for a jelly variable(jelly.value). Always begin the variable name of jelly variables with jvar_ Otherwise the Jelly master will go crazy. Which probably means that in your first <g:evaluate> will have value="jvar_value" instead.

Last thing. Remember that you can pass jelly variables inside a <g:evaluate> but it passes a copy into it what ever happens inside the <g> doesn't affect the jvar_

Hope I don't sound to stiff , just want to help so you can avoid strange errors in the future.
