Intialize javascript variable using jsp

Hello,
I am experiencing the following problem in my JSP page which uses javascript;
I need to intialize a javascript variable as follows:
rootFld = F("class").I("1.1").I("1.2")._(F("1.3").I("1.3.1").I("1.3.2"))._(F("1.4").I("1.4.1"))._(F("1.5").I("1.5.2")) ;
This variable represents a dynamic tree structure that is to be displayed on the webpage.
I need to initialize the above variable from a variable in java scriptlet. As you can see the variable is not a string and I am not sure how to initiaze it using a java variable.
Any help is much appreciated
thanks

In your jsp, set a String to the value you wish to assign to the javascript variable:
String jsVar = "whatever";
Then, set the javascript variable in the output:
<script> var myVar; myVar = <%=jsVar%> </script>

Watch out ...the double quotes in your example could cause some pain ..
