how to delete a file using checkbox!!!
i'm developing one project using the file operations implementations. I'm displaying the contents of the file in my jsp page. The first column i've putted a checkbox option and at last i've created the button. If i clicked that particular checkbox and then if i press the delete button then it should be able to delete the all check marked files from the directories.
Could anyone tell me how to do this in jsp. Is there any need for javascript or it can be done only through the jsp codings.
in advance thanks....

Use a flag called delete.Whenever you want to select a checkbox then delete should be set to true.If selecting the check box is followed by the click of the button to delete then that will generate a ActionEvent which you will receive using the Listener where you can check the value of delete flag which if its true indicates that files have been selected and you can continue deleting.If delete flag is false then you can pop a message saying no files have been selected.This selection procedure can used to perform other actions than deleting too.

function DeleteAll(){
var answer = confirm("Do you really want to delete these selected files?")
if (answer != 0) {
for(var i=0; i<3; i++){
if( (document.form1.filecheck(i).checked == true) && (document.form1.filepath(i).value != "") ){
var fso = new ActiveXObject( "Scripting.FileSystemObject" );
fso.DeleteFile(document.form1.filepath(i).value, true);
}
}
}
}
</script>

<form name="form1">
<table border="1">
<script>
for(var i=0; i<3; i++){
document.write("<tr><td><input type='checkbox' name='filecheck' value='filecheck'><br></td><td><input type='file' name='filepath'></td></tr>")
}
</script>
<tr><td colspan="2" align="center"><input type="button" name="go" value="Delete All" onClick="DeleteAll()"></td></tr>
</table>
