[aggelos]

hi,

 

i'm doing a web application and a have to do a report, so i look the webapp sample and it was very usefull, but when i try to run it into the internet explore seems like the athchment, all the images are break...how can i solve this? :unsure:

 

 

 

this is teh code:

File reportFile = new File(application.getRealPath(archivo));

 

if (!reportFile.exists())

throw new JRRuntimeException("Error al Cargar el reporte");

 

JasperReport jasperReport = (JasperReport)JRLoader.loadObject(

reportFile.getPath());

Map parametros = new HashMap();

int tipo_Equipo = ((Integer)

request.getAttribute("t_Equipo")).intValue();

String n_Equipo = (String)request.getAttribute("n_Equipo");

String usr = (String)

request.getSession(false).getAttribute("usr");

String pass = (String)

request.getSession(false).getAttribute("pwd");

String valor = (String)request.getAttribute("valor");

String iva = (String)request.getAttribute("iva");

Connection con = Persistencia.getInstance().demeConexion(usr, pass);

 

parametros.put("NUMERO" , n_Equipo);

parametros.put("tipo" , new BigDecimal(tipo_Equipo));

parametros.put("valor" , valor);

parametros.put("iva" , iva);

 

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,

parametros, con);

JRHtmlExporter exporter = new JRHtmlExporter();

 

session.setAttribute("reporte", jasperPrint);

session.setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE,

jasperPrint);

 

StringBuffer sbuffer = new StringBuffer();

 

exporter.setParameter(JRExporterParameter.JASPER_PRINT , jasperPrint);

exporter.setParameter(JRExporterParameter.OUTPUT_WRITER , out);

exporter.setParameter(JRExporterParameter.OUTPUT_STRING_BUFFER, sbuffer);

exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI ,

"servlets/image?image=");

exporter.exportReport();

 

 

PLEASE...HELP ME...IT'S VERY URGENT:pinch:

 

THANKS,

Are you sure, that the image-servlet actually delievers the images?

[aggelos]

u r talking about this line:

exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI , "servlets/image?image=");

? in the webapp sample is ../servlest...but i configured my webmodule without this...for example if i have a directory named jsp in the web module i accessed to it like jsp/X.jsp an not like ../jsp/X.jsp...so i just remove the "../" at the beginning ... but it doesn't work...:(

 

i really don't knwo how to solve it...please help me...

 

Thanks,

i forgot to tell u that i don´t have a servlets/image directory...but i didn't see it in the webapp sample...for that reason i didn't create that...does it the problem? how can i solve it?

Study the webapp example carefully. You need to configure your web application server correctly.

 

The URL path "servlets/image" is not a path in the filesystem, it is an assignment of a servlet class.

 

See the file WEB-INF/web.xml in the example:

Code:

<servlet-mapping>
 <servlet-name>ImageServlet</servlet-name>
 <url-pattern>/servlets/image</url-pattern>
</servlet-mapping>

 

The servlet-name refers to the servlet class:

Code:

[code]<servlet> <servlet-name>ImageServlet</servlet-name> <servlet-class>net.sf.jasperreports.j2ee.servlets.ImageServlet</servlet-class> </servlet>

 

This class is located in WEB-INF/classes/net/sf/jasperreports/j2ee/servlets/ImageServlet.

 

Again: it looks like a missing configuration for the servlet. If you use Tomcat you can copy the existing WEB-INF directory or copy the required configuration parts and classes to the WEB-INF to your existing application. For other web application servers you may need additional steps, consult the server docs about adding a servlet.
