Reg : Using Arithematic Operators in Template

Question

Hi,
I'm stuck with a small issue ie using arithematic operator in velocity template.
Please find the below code.
Bean Class : Graohics Bean
private String Width="250";
public void setWidth(String Width) {
this.Width = Width;
public String getWidth() {
return (int)(Integer.parseInt(Width)/0.75) + "";
Template Class :
#set($pwidth = "$graphicsAttributes.Width")
#set($pwidth1 = $pwidth + 20)
I am trying to add +20 to $pwidth1 which is returning string therefore the value is jus appending no acutual logical operation happening.
Can we convert String to Integer in a velocity template? .
Kindly help me out in solving this issue.

Answer 1

Well, your #1 is what Reports is designed to do.
You could do #2 if and only if the report is
always formatted exactly the same and only the
data values changed. And, your fields would have
to be fixed in size because #2 wouldn't support
elasticity at all.
#2 could be done with a separate program that
updated fields in an existing RTF file with new
data values, but it wouldn't be Oracle Reports
any more...
(You don't want to generate variable RTF
yourself. Reports has lots of bugs in its RTF
generator, but it's still better than writing it
yourself!)
