Jasper HTML

hi experts i have a problem in my code for generating pdf

JasperRunManager.runReportToPdfStream(reportStream,servletOutputStream,new HashMap(), resultSetDataSource);

when This line is executed the content of database shows in pdf format on browser

but i want ro show the plain text on browser..
i did the following changes

response.setContentType("text/plain");

JasperRunManager.runReportToHtmlFile(jasperReport,new HashMap(), resultSetDataSource);

but it saves the html file in plain text format in my project folder..
but i want to show on broswer how can i do????

Mick Barry

runReportToPdfStream() produces pdf data, you need to use something different to generate a plain text report
