[JBoss Seam] - Re: Generation of jasper reports in seam
by jazir1979
Hi,
I wrote my own JSF component that can view a report inside a div on a given page, and also export a report in a number of output formats. I can't really share the component at this stage, but these snippets should help you get something up and running. Hopefully in the future I can make my component more generic and get permission to contribute it in full.
To view the report, firstly I create the JasperPrint object which is the result of filling the report (JasperFillManager.fillReport()). The following code is inside my customer JSF component and the context variable you see is the FacesContext... however the export gets triggered directly from a Seam action, where you can inject the FacesContext using @In, so you should be able to do this without having to write a JSF component.
| if (jasperPrint != null) {
| final JRExporter exporter = new JRHtmlExporter();
| exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
| exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, context.getResponseWriter());
| exporter.setParameter(JRHtmlExporterParameter.HTML_HEADER, "");
| exporter.setParameter(JRHtmlExporterParameter.HTML_FOOTER, "");
|
| // images
| final HttpServletRequest request = (HttpServletRequest) context.getExternalContext().getRequest();
| request.getSession().setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE,
| jasperPrint);
| exporter.setParameter(JRHtmlExporterParameter.IMAGES_MAP, new HashMap<Object, Object>());
| exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI,
| request.getContextPath() + "/jasperimg?image=");
|
| // export
| try {
| context.getResponseWriter().write("<div class=\"reportview\">");
| exporter.exportReport();
| context.getResponseWriter().write("</div>");
| } catch (final JRException e) {
| LOG.error("Report exporting error", e);
| .....
| }
| }
|
To export the report in a whole new response
| final JRExporter exporter = JRExporterFactory.getExporter(outputType, jasperPrint, context);
| final ByteArrayOutputStream stream = new ByteArrayOutputStream();
| exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, stream);
|
| // export
| try {
| exporter.exportReport();
| } catch (final JRException e) {
| LOG.error("Report exporting error", e);
| ....
| }
| final HttpServletResponse response =
| (HttpServletResponse) context.getExternalContext().getResponse();
| try {
| final OutputStream responseStream = response.getOutputStream();
| response.setContentLength(stream.size());
| response.setContentType(contentTypes.get(outputType));
| if (outputType != ReportOutputType.HTML) {
| response.setHeader("Content-Disposition", "attachment; filename=report." + outputType);
| }
| responseStream.write(stream.toByteArray());
| responseStream.flush();
| responseStream.close();
| response.flushBuffer();
| } catch (final IOException e) {
| LOG.error(e);
| ....
| }
| context.responseComplete();
|
|
I hope this helps you to get it working,
Daniel.

[JBoss Seam] - process entity from GET request
by nicolasb
hello,
I display Information about an entity with a GET request by using a stateless bean and page parameter in the pages.xml.
on this page which displays a single item i want to execute a conversational bean in which i would like to access the item:
| <h:form>
| <h:inputHidden value="#{item.id}"/>
| <h:commandButton type="submit" action="#{bean.addItem}"/>
| </h:form>
|
doesn't seam to work since as soon as i add the inputHidden Parameter the addItem won't get executed.
the item is somehow loaded into:
| @In
| Item item;
|
because if omit this fragment a exception is thrown regarding the missing input.
it works perfectly fine if i use a different entity. it only breaks as soon as i try to access the entity of the previous GET request
i'm not sure where to continue
thx for any help

can anyone pls. help with this
I am assuming that JBossWS 1.2.1 can be run on JBoss 4.0.5 server, although the following line in installation guide makes me suspicious:
anonymous wrote : Currently, we have integration layers for the JBoss application server (> 4.0.5.GA) and Apache Tomcat.
