How to locate and register custom js

Hi @TDT 

Reference topic: custom Picker Callback not working - PTC Community

Can you please show me the exact way and location to register custom js

In my case I have created custom js and registered at this location Windchill\codebase\netmarkets\jsp\custom\contextPickerJSP.jsp

<%@ include file="/netmarkets/jsp/util/begin.jspf"%>
<%@ taglib uri="http://www.ptc.com/windchill/taglib/core" prefix="wc"%>

<script type="text/javascript"
src="<%=request.getContextPath()%>/netmarkets/javascript/custom/contextPickerHelper.js">
</script><%@include file="/netmarkets/jsp/util/end.jspf"%>
