    Question How to Declare Global Variables??

    I am just starting out with Java, and I have been fairyl sucessful with creating some basic JSP's.

    I am attempting to convert a VB project into a Web application...

    I have a question though, that I have been unable to find a clear cut answer to...and that is, how can I declare Global variables within a JSP that can be called from other JSP's...

    or am I going about the theory all wrong...For example when I have the user select a month & year on a JSP, and then they click on a Submit button, this should take them to the next JSP, which will need to have the values of the month year to use within a SQL statement...

    I hope that I am clear, and I hope that someone can give me some helpful pointers...

    Thank you!

    You would need to either add to the query string or add the variables to the session.

    Sorry, can't provide a specific example. I haven't used Java in a while.

    I appreciate your response, but unfortunately I am going to need a little bit more...such as how to add the vaiables to a session, or to the query string??

    I have the variables stored in the following way:
    Code:
    <html>
<title>Selection</title>
<head>


<script language="JavaScript">
function Month()
   {
   var m = document.form2.list2.selectedIndex;
   
   }
function Year()
   {
   var y = document.form1.list1.selectedIndex;
   
   }
</script>

<FORM><style media="screen" type="text/css"><!--
.plainText {font-family: arial; font-size: 8pt; font-weight: normal; color: black; text-decoration: none}
A  {color: black; font-weight: normal; font-size: 8pt; font-family: arial, helvetica, sans-serif ; text-decoration: none; pt: font-family: arial, helvetica, sans-serif  }
A:hover {color: red; font-weight: normal; font-size: 8pt; font-family: arial, helvetica, sans-serif ; text-decoration: none; pt: font-family: arial, helvetica, sans-serif}
A.final:active { color: black; font-weight: bold; font-size: 8pt; font-family: arial, helvetica, sans-serif; text-decoration: none; pt: font-family: arial, helvetica, sans-serif  }
.topbarText1 { font-family: Arial; font-size: 10pt; font-weight: bold; color: #FFFFFF; text-decoration: none }
.topbarText2 { font-family: Arial; font-size: 8pt; color: #FFFFFF; text-decoration: none }
.bannerText { font-family: Arial; font-size: 8pt; font-weight: bold; color: #000000; text-decoration: none }
.topbarText { font-family: Arial; font-size: 8pt; font-weight: bold; color: #FFFFFF; text-decoration: none }
.topbarText:hover { font-family: Arial; font-size: 8pt; font-weight: bold; color: red; text-decoration: none }
--></style>

<tr><font color=white>Space</font></tr>
<td width=900 align=center><font size = 5 color="330099"><b>Please select the Year, Month or Quarter</b></font><p>

<FORM NAME="form1"><font size=3 color="990033">Year

<SELECT NAME="list1" onChange="Year()">
<OPTION VALUE="2004">2004
<OPTION VALUE="2005">2005
<OPTION VALUE="2006">2006
<OPTION VALUE="2007">2007
<OPTION VALUE="2008">2008
<OPTION VALUE="2009">2009
<OPTION VALUE="2010">2010
<OPTION VALUE="2011">2011
</SELECT>
</FORM>

<FORM NAME="form2"><font size=3 color="990033">Month
<SELECT NAME="list2" onChange="Month()">
<OPTION VALUE="January">January
<OPTION VALUE="February">February
<OPTION VALUE="March">March
<OPTION VALUE="April">April
<OPTION VALUE="May">May
<OPTION VALUE="June">June
<OPTION VALUE="July">July
<OPTION VALUE="August">August
<OPTION VALUE="September">September
<OPTION VALUE="October">October
<OPTION VALUE="November">November
<OPTION VALUE="December">December
</SELECT>
</FORM>
<form name=f2 action='selection2.jsp'>
<center><input type=submit value='Complete' name=></center>

</table>
</center>
</body>
</head>
</html>
    So when the next JSP loads I need to pass the values for the month and year which are set to m & y from the functions above...

    Any help will be greatly appreciated!
