Calling if
Hi,
I have an if statement in my jsp program which fetches me the value of next button.
Vector v1991=new Vector(30);
if(request.getParameter("submitxyz")!=null)
{
x=x+10;
v1991=mb1.Sel(x);
}
for()
{
}
But this would execute only once.I want that as soon as for loop is finished,the control should go back to the if statement and if I press the button,the action should happen again.i.e.,every time after finishing for loop,if I press the button submitxyz, x value should b incremented by 10,till it reaches the last record.i.e. till vector v1991 becomes empty.Can anyone help plz?Plz let me know if u have any doubts.Till now,even a single doubt has not been clarified.Plz help...I shall b very thankful....

Hi,
My program is something like this:
java.util.Vector v1991=new java.util.Vector(30);
int f1=1;
int f2=10;
v1991=mb1.Sel(f1,f2);
// Here,mb1 is the bean and sel is the function where I select the
// records between employee number f1 and f2
if(request.getParameter("submitxyz")!=null)
{
f1=f1+10;
f2=f2+10;
v1991=mb1.Sel(f1,f2);
}
// submit xyz is my submit button.I get records 11 to 20 on submit
// but I need to get back here and if I click this again, I should get
// records 21 to 30.Again on click,I should get 31 to 40 and so on.
for(int l=l1;l<=(v1991.size()/6);l++)
{
<tr>
<td width="8%">
<form method="get" name="form1" action="content.jsp">
<fieldset>
<input type="radio" name="radio" value="<%=v1991.get(i)%>">
</fieldset>
</td>
<td width="7%">
<%
out.println(v1991.get(i).toString());
i++;
%>
</td>
<td width="17%">
<input type="text" name="text222" value="<%=v1991.get(i).toString()
%>">
<%
i++;
%>
</td>
<td width="17%">
<input type="text" name="text333" value="<%=v1991.get(i).toString()
%>" >
<%
i++;
%>
</td>
<td width="17%">
<input type="text" name="text444" value="<%=v1991.get(i).toString()
%>">
<%
i++;
%>
</td>
<td width="17%">
<input type="text" name="text555" value="<%=v1991.get(i).toString()
%>">
<%
i++;
%>
</td>
<td width="17%">
<input type="text" name="text666" value="<%=v1991.get(i).toString
().toString().substring(0,10)%>">
<%
i++;
%>
</td>
</tr>
<%
}
%>
Now,I want to go back to if() statement as soon as I finish this loop.This program would give me 1 to 10 records initially.When I click submitxyz (next) button,I would get 11 to 20.As soon as I get 11 to 20,if I click the button,I want to get 21 to 30.But it doesn't work...
my select query would be select * from emp where empno between f1 and f2;
(There is no problem with the syntax or query.The only problem is how to return to if() statement);
Plz help me ...........Pleeeeeeeeease....I shall be very thankful.
