Statement msqlStatement = null ;
ResultSet mrs = null ;
Connection mconn = null ;
ExternalContext econtext = getExternalContext();
InputStream stream = econtext.getResourceAsStream(reportSource);
if (stream == null) {
throw new IllegalArgumentException("Unknown report name '" + reportSource
+ "' requested");
try {
String mfat = ac_categoryDataProvider.getCachedRowSet().getDataSourceName();
javax.naming.Context mctx = new javax.naming.InitialContext() ;
DataSource mds = (DataSource)mctx.lookup(mfat);
Connection mcon= mds.getConnection();
mcon.setAutoCommit(false) ;
JasperPrint jasperPrint = null;
//getSessionBean1().getTripRowSet(),
//getSessionBean1().getAc_categoryRowSet(), mfat getSessionBean1().getAc_categoryRowSet()
jasperPrint = JasperFillManager.fillReport(stream, null,mcon);
JRExporter exporter = null;
HttpServletResponse response = (HttpServletResponse)econtext.getResponse();
FacesContext fcontext = FacesContext.getCurrentInstance();
exporter = new JRPdfExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_STREAM,
response.getOutputStream());
exporter.exportReport();
fcontext.responseComplete();
} catch (Exception ex) {
log(" Error Description" , ex);

Thanks Sven.
The query works but the other way. The output is for all the targets, not for the respective target which we select from :p1_target.
select target_name,target_type, column_label,
warning_threshold,critical_threshold,occurrence_count
from sysman.MGMT$TARGET_METRIC_SETTINGS@crmodem
where target_name in (select MEMBER_TARGET_NAME from MGMT$TARGET_FLAT_MEMBERS@crmodem
where upper(AGGREGATE_TARGET_NAME) like '%X' || :P1_TARGET || '%')
Thanks again.
