[Summing strings]

Hi. I have fields like

200.000

10.000

5.000

they are in a string. I want to sum them that and print it in the right format, 215.000 in this case. 

I tried creating a variable with the expression Double.parseDouble ($F{field20}) but it didn't work

 

[memory leakage while generating swap file with string as aparameter in to jasper]

maybe the problem is in the compiling of the jrxml, that's a common memory leakage problem. Instead of something like this 

JasperCompileManager.compileReportToFile(inputFile, destinationFile);

try

String inputFile = 
session.getServletContext().getRealPath("InputFile.jrxml");

String destinationFile = 
session.getServletContext().getRealPath("InputFile.jasper");

File jasperFile = new File(destinationFile);

if(environmentBeanFile.exists() == false)
{
JasperCompileManager.compileReportToFile(inputFile, destinationFile);
}

 

 

[Group inside a group]

Hi. Is it possible to create a group inside a group in JasperSoft Studio?

Currently I created a group so it displays the header and then the data. but I want to group the data again inside this group and to display the headers whenever a new subgroup is made.
