Hello, I am using JDev 11.1.1.2.
I have a page into a bound Task FLow containing a pivot table and a "print "button".
I am using Jasper Report to create a PDF document.
I want this document to be opened into a new Window when the user click on the button.
I've been reading several threads/blogs to do this but it is not working.
Here the code of my button:
<af:commandButton text="Print"
id="cb1" useWindow="true"
action="#{viewScope.myBean.goReport}"
windowHeight="400" windowWidth="800"
immediate="true"/>
where viewScope.myBean.goReport returns "dialog:goReport"
Here the code I use to create my PDF:
// Create a PDF exporter
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
JasperExportManager.exportReportToPdfStream(print, byteArrayOutputStream);
FacesContext context = FacesContext.getCurrentInstance();
ExternalContext ectx = context.getExternalContext();
HttpServletResponse response = (HttpServletResponse)ectx.getResponse();
ServletOutputStream out = response.getOutputStream();
response.setHeader("Cache-Control", "max-age=0");
response.setHeader("Content-Disposition", "inline; filename=report.pdf");
response.setContentType("application/pdf");
// response.setContentLength((new Long(userInfoBean.getReportStream().length)).intValue());
out.write(byteArrayOutputStream.toByteArray());
out.flush();
out.close();
context.responseComplete();
Into my bounding task flow containing the page I have:
<view id="report">
<page>/report/report.jspx</page>
</view>
<from-activity-id>*</from-activity-id>
<control-flow-case id="__1">
<from-outcome id="__2">dialog:goReport</from-outcome>
<to-activity-id id="__3">report</to-activity-id>
</control-flow-case>
My report.jspx file i just a blank page attached to a backing bean:
<?xml version='1.0' encoding='windows-1252'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
<jsp:directive.page contentType="text/html;charset=windows-1252"/>
<f:view>
<af:document id="d1" binding="#{backingBeanScope.backing_report_bean.d1}">
<af:form id="f1" binding="#{backingBeanScope.backing_report_bean.f1}"></af:form>
</af:document>
</f:view>
<!--oracle-jdev-comment:auto-binding-backing-bean-name:backing_report_bean-->
</jsp:root>
I cannot get the PDF document to open into a new Window
If I put alone "dialog:goReport" into the button action attribut, I manage to have a blank page opened.
I I link "viewScope.myBean.goReport" method which is returning "dialog:goReport" and contains the PDF creation code to the button action I have the PDF document appearing but into the current window.
I tried putting also my PDF creation code into a launchListener, actionListener, returnListener but I still have my PDF document opening into the current window.
I am sure I am doing something wrong since it appears others have found a way to do it but I'm lost right now.
Can someone help me on this pls.
Jack
