when i pass connection in jasperPrint it gives exception.

jasperPrint = JasperFillManager.fillReport(jasperReport,map, reportConnection);

I am also using a subreport so that is why i am not using JRResultSetDatasource and using connection. I am just stuck into this. but when i pass JRResultSetDatasource it works fine and when i also pass connection object in a hasmap parameter it gives and error. the above exception.
@Bear Bibeault ....I have checked the dom of manually created table and the dynamic one, each and everything is same but still not working .
I have created a dynamic table in jquery and using draggable() to move the table columns (reordering). but it is not working. when i create a table manually then it is working fine, the columns are also moving, what am i doing wrong when i create a dynamic table then use draggable() by dynamic table id. I have been stuck in this problem from last couple of days. Here is my code.

function addTab() {
var tab_title = $tab_title_input.val() || 'Tab '+tab_counter;
//alert(tab_title);
$tabs.tabs('add', '#tabs-'+tab_counter, tab_title);

var newTableDiv = $("<div />",{id: 'dialog'+tab_counter});
newTableDiv.appendTo("body");
alert("div appended to body"+" "+'dialog'+tab_counter);
var setCSS = {
'width' : '100%',
'cellSpacing' : '1px',
'cellpadding' : '2px'
}

var newTable = $('<table class="ui-widget">'+
'<thead id="myTableHead'+tab_counter+'" class="ui-widget-header">'+
'<tr><th><strong>Symbol</strong></th>'+
'<th><strong>Price</strong></th>'+
'<th><strong>Volume</strong></th>'+
'<th><strong>Buy</strong></th>'+
'<th><strong>Sell</strong></th></tr></thead>'+
'<tbody id="sortable'+tab_counter+'" class="ui-widget-content">'+
'<tr><td>PSO</td><td>100.00</td><td>12</td><td>120.00</td><td>130.00</td></tr>'+
'<tr><td>ASO</td><td>200.00</td><td>11</td><td>120.00</td><td>130.00</td></tr></tbody></table>').attr('id', 'myTable'+tab_counter).css(setCSS);
$(newTableDiv).append(newTable);
$('#myTable'+tab_counter).draggable(); //This is draggable
$('#myTable'+tab_counter).tablesorter();
$( '#sortable'+tab_counter).sortable();
}

Hi

I have created an applet and made its jar file in Netbeans. i am using a jar file in an applet.
I am calling the applet.jar in a jsp page. The applet works fine but the functionality it has to be achieved is through the another jar file which i was using in that applet. means how to include an external jar file in applet.jar so that it could also be available to that jsp page also when i will run the jsp page. I need an urgent help. thnx

Hi,

I have a little problem. i am using jinvoke library to call the user32.dll methods. I have developed an applet in netbeans which call the User32.dll methods using jinvoke it works fine in netbeans but when i run an applet in the browser (the html one) it shows the GUI but not invoking the methods. I think it cannot find the jinvoke library. So how to deploy the applet along with the jar file which is jinvoke.

thanks
