Hi, this is shanmugaraj. I have more than two years of experience in jasperreport development. I have migrated around 30+ crystal reports to jasper reports. Worked on charts, dashboard, adhoc and jrxml based reports. Have worked on complex reports, the complex report's requirements cannot solve in the reporting side itself, So have created java methods, which will return java collocations to fill the data in the jrxml reports. I have used Mysql and Oracle as database in the report development.
