dheeraj.madhu's post in Getting net.sf.jasperreports.engine.JRRuntimeException: org.mozilla.javascript.EcmaError: TypeError: Cannot read property "length" from undefined Exception was marked as the answer
Issue is solved.
When the data set is empty high chart still try to render the chart and it will fail. To prevent it added print when condition for chart element in report jrxml.
<printWhenExpression><![CDATA[$V{REPORT_COUNT} > 0]]></printWhenExpression>[/code]

dheeraj.madhu's post in Report has only one row when xml data source is used was marked as the answer
Passing the xml path while creating the data source fixed the issue.
Used following constructor to create a new xml data source
JRXmlDataSource source = new JRXmlDataSource(new File(file,"/response/results/field");[/code]
Then removed query String from jrxml. Modified field section looks like below
<field name="field" class="java.lang.String"> <fieldDescription><![CDATA[child::text()]]></fieldDescription></field><field name="count" class="java.lang.String"> <fieldDescription><![CDATA[@count]]></fieldDescription></field>[/code]
