Zero file size of exported XLS file

[tbiswas]

Hello,

I have posted this topic in jasper server's forum, but no replies.

I am new to JasperServer and iReport tools. I have created one .jasper file using iReport for testing. In my tomcat I have used all the required JAR files for JasperServer. I have created one JSP file and want to create report based on that .jasper file into different file format like PDF, CSV, RTF, XLS etc. My JSP code is in Code section: -

Problem with this code is, all the other file format is working properly except the xls format. It produsing an empty file with no data.

Can anybody please help me on this issue?

Am I doing any silly mistake?

I need help on this.

Thanks in advance...
