It will give 1st date of next month, but i dont want that date and I want to display warning message 'Invalide date' something like this.

Hi,
I'm planning to write generic class to validate any date format and DATE_PATTERN regex will be passed to validate method based on date format.
By using DateFormat, if parse (date format yyyymmdd) String date = "20121301"; I will get Tue Jan 01 00:00:00 IST 2013 but which is wrong date(month is wrong).

thanks for your reply.

Hi All,
I am validating date using regex and I'm trying to get matcher groups and getting wrong values. Can anyone check and let me know what i'm doing wrong.

import java.util.regex.Matcher; import java.util.regex.Pattern; public class CheckDate { // private static final String DATE_PATTERN = // "((19|20)\\d\\d)(0?[1-9]|1[012])(0?[1-9]|[12][0-9]|3[01])"; private static final String DATE_PATTERN = "((19|20)\\d\\d)(0[1-9]|1[012])(0?[1-9]|[12][0-9]|3[01])"; private Pattern pattern; private Matcher matcher; public static void main(String[] args) { CheckDate date = new CheckDate(); boolean flag = date.validate("20120131"); System.out.println("date flag is::::::::::" + flag); } private boolean validate(String date) { pattern = Pattern.compile(DATE_PATTERN); matcher = pattern.matcher(date); if (matcher.matches()) { System.out.println("matched.................."); matcher.reset(); if (matcher.find()) { System.out.println(matcher.groupCount()); System.out.println(matcher.group(1) + " and " + matcher.group(2) + " and " + matcher.group(3)+" and "+matcher.group(4)); int year = Integer.parseInt(date.substring(0, 4)); String month = date.substring(4, 6); String day = date.substring(6, 8); if (day.equals("31") && (month.equals("11") || month.equals("04") || month.equals("06") || month.equals("09"))) { return false; // only 1,3,5,7,8,10,12 has 31 days } else if (month.equals("02")) { // leap year if (year % 4 == 0) { if (day.equals("30") || day.equals("31")) { return false; } else { return true; } } else { if (day.equals("29") || day.equals("30") || day.equals("31")) { return false; } else { return true; } } } else { return true; } } else { return false; } } else { System.out.println("not matched.................."); return false; } } }

Hi All,

How JVM will find is loading file is class or interface. How it will find extended/implemented files.

Thanks.

Ok, got your point.
We are planning to mount folders which contains excel files (these files will be used by exe). we will place exe file in unix environment itself.

Thanks Rob/Jan,

We are calling with in our network only and I got one option to call windows services using FreeTDS.
and we are checking to mount windows folder and use it in unix machine(not calling exe/ control files).

Thanks Nitin,

Can you please explain in details, I have no idea how to communicate between unix and windows.
If possible please provide any documents, it will be very helpful.

If I call below code what will happen, does it execute windows exe file?
Runtime r=Runtime .getRuntime(); r.exec("nn.bat");

Hi All,

I want to call exe file which is place in windows environment from Unix operatign system, unix and windows server are place in same organization (different countries).

Can any one tell how can I call exe file.

Nitin/Subramani,

I have updated setHeader before calling getOutputStream and still I am getting same error.

No Rob,
i have button info in jsp and control login in java class.
I have checked my controller logic, but still i'm getting same error
and my jsp code is:
<div id="importform" class="div_form_horizontal"> <form:form name="report_criteria" method="POST" action='<%=request.getContextPath()+"/reportFiles.do?method=generateReports"%>' commandName="criteriaBundle"> <table class="tbl_form_horizontal"> <tr> <td> <form:errors path="*"/> </td> </tr> <tr> <td class="col_label"> <spring:message code="generic.app.report" /> </td> </tr> <tr> <td class="opbuttons"><br/><br/> <div class="buttonwrapper"> <a class="squarebutton" href="#" onclick="document.report_criteria.submit()"><span>Generate Reports</span></a> </div> </td> </tr> </table> </form:form> </div>

Hi Rob,
Thanks for your reply,
i have only one button in my jsp and my logic is in controller class only.

Thanks.

Thanks Rob.

Haina, Thanks for your conformation.
I have done java part and waiting .net team to provide exe.
and one more boubt, do have to install .Net framework in my system to execute exe file ?? and what about is place exe in shared system ??
