Variable value assignment in Oracle Data Integrator

Question

<?
String mystr =  "#MY_ODI_VAR";
out.print(mystr);
?>

I want to assign value stored in an ODI variable (MY_ODI_VAR) to another variable (mystr) defined inside Java Code in a procedure. How can this be done. The above mentioned code is producing #MY_ODI_VAR instead of the value assigned to this variable. I have also tried following variations, but no luck.

Thanks

<?
String mystr =  "<% #MY_ODI_VAR %>";
out.print(mystr);
?>

<?
String mystr =  <% "#MY_ODI_VAR" %>;
out.print(mystr);
?>

Answer 1

With the question mark tags <? ?> the code is generated before ODI variables are substituted.

Using the dollar tags <$ $> instead should work. It generates the code after ODI variables are substitued.

<$
String mystr =  "#MY_ODI_VAR";
out.print(mystr);
$>

Here is a longer explaination about the 4 different substitution tags.
