Hie,
I need to to round double value to a 2 decimal point value.However,
the value is to be round up instead round down as per default.
E.g : 2.142 -> 2.15 (default is 2.14)
or 2.1425 -> 2.15 (default is 2.14)
Code shown below return a round down value.
***********************************************
try {
DecimalFormat df = new DecimalFormat("RM#,###,###,###.00");
if (!val.equals(null) || !val.equals("")) {
val=df.format(val);
}
} catch (Exception e) {
System.out.println(String.valueOf(e));
}
return val;
**********************************************
Anyone have any idea?
Thanks~!!

hei evryone!


Does anyone knows how to solve this bug?

java.io.IOException: Corrupt form data: premature ending

Im using Oreilly's cos.jar MultipartRequest
here is my form :
function save()
{
var agree = confirm("Are you sure you wish to submit this form ?");

if (agree)
{
document.form1.action="../servlet/ehr.toll.ats.AtsGlcMultipartServlet";
document.form1.encoding = "multipart/form-data";
document.form1.al.value= "submit";
document.form1.sy.value= "EXTERNALCOURSEDIRNEW";
document.form1.submit();
}

}
<form name="form1" method="POST" action="" id="form1">

<table cellspacing=1 cellpadding=4 width="100%">
<tbody>
<TR>..............</TR>
<TR>..............</TR>
<TR>..............</TR>
<TR ALIGN="left" VALIGN="top">
<td class=bg6 width="30%"><span class="textb">Brochure Attachment</span></td>
<TD class=bg7><span class=textdata>File Name

</span></TD>
</tr>
<TR>..............</TR>
<TR>..............</TR>

</tbody>
</table>
</form>

HERE IS AtsGlcMultipartServlet which is a servlet :

}

try

}
catch (IOException ioe)
{
//ignore
System.out.println("error-"+ioe);
}

if (multi != null)
{
sy = Util.nullCheckStr(multi.getParameter("sy"));
al = Util.nullCheckStr(multi.getParameter("al"));

String syParam = "?sy=" + sy;
String syParam2= "&al=" + al;


System.out.println("sy-"+sy);
System.out.println("al-"+al);

if (sy.equals("EXTERNALCOURSEDIRNEW"))
{
if (al.equals("submit"))
{
request = AtsGlcControlServlet.atsGlcExtCrsDirMulti(request,"submit",multi);
request = AtsGlcControlServlet.atsGlcExtCrsDir(request, "view");
syParam = "?sy=EXTERNALCOURSEDIR";

nextPage = nextExtPage2 + syParam;
}
}
else
{
logOut(request, response, "nopage");
}
}
else
{
logOut(request, response, "nopage");
}
response.setContentType("text/html");
response.setHeader("Cache-Control", "no-store");
response.setHeader("Pragma", "no-cache");
RequestDispatcher disp = getServletContext().getRequestDispatcher(nextPage);
disp.include(request, response);

}
catch(Throwable theException)
{
// uncomment the following line when unexpected exceptions
// are occuring to aid in debugging the problem.
if(SecurityProperty.getPrintStack())
{
theException.printStackTrace();
}
}
}
It able to upload the file into the directory.
However,the IOException causing other data insert to halt..
Searching on google doesn't provide much help..

Your response would be deeply appreciated.

Thankz

Thanks for advice...

After few changes..i managed to get it done.
Unfortunately,new problems arise along..
My system has alot of folders which contain lots of servlets..(.class)
do i have to declare all of them and map it in web.xml one by one..

examples:

my login.jsp will post value to login.class(login folder) which will import util.class(in system folder) to use DCconnect() to verify the login..then..if valid..
login.class will call welcome.jsp

do i have to..
write...
< servlet > ...
< servlet > ...
< servlet-mapping > ...
< servlet-mapping > ... for all the servlet?
if kinda of troublesome,rite?

hie there..

i am new to JSP and tomcat...
what i understand about JSP is it used to display the output while the servlet will do the processing.

Here is basically what i wanna implement in my web application..

user->JSP(form)->pass the value to servlet(.java)->processing value(servlet)->pass the output to JSP->display out(JSP).

i know that all JSP files should put in ../tomcat/webapps/ROOT/
but how about the servlet?...i tried putting it in ../ROOT/WEB-INF/classes
but it gives me errors...

i check in Internet..and most of them told me that i should set the classpath of the servlet the i wanna use..i tried but still give me errors.

anyone?

<%
// I invalidate all my session when i logout and comes on Login.jsp page but if i go back still it open
previous pages
How i can stop these
i am adding these line in avery jsp page
1)
response.setHeader("Pragma","no-cache");
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires", 0);
%>

2) and in Logout.jsp
session.invalidate();
response.sendRedirect("Login.jsp");

still on reaching login page i can move to previous page by clicking back button
