having problems to generate pdf in struts app

Hi,

I want to use jasper reports to generate pdf in a struts action class.
Here is the code segment
//////////////////////////////////////////////////////
try {
JasperCompileManager.compileReportToFile(fileName + ".xml");
Map parameters = new HashMap();
JasperRunManager.runReportToPdfFile(fileName + ".jasper", parameters, new JREmptyDataSource());
_log.debug("fileName: " + fileName + ".xml");
}
catch (JRException e) {
e.printStackTrace();
}

try {
// hard coded for demo
InputStream content = new FileInputStream(fileName + ".pdf");

// XXX Need to buffer this a little.
int b;
while( (b = content.read()) != -1 ) {
outputStream.write( b );
}

content.close();
} catch( java.io.IOException e ) {
_log.error( "error", e );
//////////////////////////////////////////////////////////


I got the following error message when I try to generate a pdf file use this struts app after I deployed it in weblogic server 6.1. Note: Although I can use jasper reports to do the same when I run it as an stand alone java app.
