spring - Cannot load data from database to chart using extjs -



spring - Cannot load data from database to chart using extjs -

i'm using spring , hibernate display extjs chart database. but, when i'm pointing out url controller, not caling . check reference in dispatcher servlet

<bean id="urlmapping" class="org.springframework.web.servlet.handler.simpleurlhandlermapping"> <property name="mappings"> <props> <prop key="index.htm">indexcontroller</prop> <prop key="loadchart.htm">empcntrl</prop> </props> </property> </bean> <bean name="empcntrl" class="com.hclt.controllerr.contrler" />

script code follows:

function loadchart(){ ext.chart.chart.chart_url = 'images/charts.swf'; var store = new ext.data.jsonstore({ fields: ['depname', 'count'], url: 'loadchart.htm' }); new ext.panel({ width: 400, height: 400, title: 'employee details', renderto: 'chartdiv', items: { store: store, xtype: 'piechart', datafield: 'depname', categoryfield: 'count', //extra styles applied chart defaults extrastyle: { legend: { display: 'top', padding: 5, font: { family: 'tahoma', size: 13 } } } } }); }

although you've created store doesn't auto-load default.

either add: autoload: true config of store

or

call store.load() somewhere in function.

spring extjs
