jasper Report Pdf file opening problem

[logudotcom]

Dear All,

 

i have been using jasper report for a project. i did not write query in report query or query string(jasper report) instead query is constructed in java page and result is passed as a arraylist to the report to show the report i use acrobat reader.

 

when i load the answer to the acrobat reader5.0 the result is not shown until i refresh the page but i can get the result in the first time itself.

 

when i use acrobat reader version 6.0 and the above.

so plz can any one say wheather it is a problem in version or the code need to be changed.

 

the code is as follows.

 

ServletOutputStream servletOutputStream = response.getOutputStream(); URL url = ClassLoader.getSystemResource ( "file:" + servlet.getServletContext ( ).getRealPath ( "reports" ) + "/sponsor/PrintLabel.jasper" ); if ( url == null ) url = new URL ( "file:" + servlet.getServletContext ( ) .getRealPath ( "reports" ) + "/sponsor/PrintLabel.jasper" ); response.setContentType ( "application/pdf" ); InputStream inputSt = url.openStream ( ); InputStream reportStream = inputSt; Sponsor[] spo=(Sponsor[]) listLabel.toArray(new Sponsor[0]); JRBeanArrayDataSource beanCollectionDataSource = new JRBeanArrayDataSource ( ( spo ) ); JasperRunManager.runReportToPdfStream ( reportStream , servletOutputStream , new HashMap ( ) , beanCollectionDataSource ); servletOutputStream.flush ( ); servletOutputStream.close ( );
