How to return a DataTable from a Java class to a JSP (Javascript code)?

[Rui Maia]

On a Java class:

public DataTable GetDT(...) {

// Create a data table.

   DataTable result = new DataTable();

   ArrayList<ColumnDescription> cd = new ArrayList<ColumnDescription>();

    cd.add(...);

    cd.add(...);

   cd.add(...);

   result.addColumns(cd);  

            ....

           return result;

}

....on JSP

<script type='text/javascript' src='https://www.google.com/jsapi'></script>

<script>

// Load the Visualization API and the piechart package.

google.load('visualization', '1', {packages:['corechart', 'table']});

google.setOnLoadCallback(drawTable);

function drawTable() {

var dataD = <%=myDBUtils.GetTransfersByDateRangeDailyDT(null, null, startDate, endDate)%>;

var optionsExtD = {

    title: 'xxxxxx',

    hAxis: {title: 'xxxx', titleTextStyle: {color: 'red'}}

   };

var chartD = new google.visualization.Table(document.getElementById('table_div-D'));

       chartD.draw(dataD, optionsExtD);

}

</script>

NOT WORKING. Any HELP?

More info... the Google Chrome developper tools identify this problem:

(syntax error: unexpected number)...

var dataD = 2013-10-07,1.0,000001

2013-10-07,1.0,000003

2013-10-07,1.0,000005

2013-10-07,1.0,000007

2013-10-07,1.0,000009;

Your function myDBUtils.GetTransfersByDateRangeDailyDT is not returning a DataTable object.
