-------------------------------------------
Key: WICKET-2228
URL: https://issues.apache.org/jira/browse/WICKET-2228
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4-RC2
Environment: Windows XP -jdk 1.6 Tomcat 6.0.16
Reporter: Teddy Clermont
Priority: Critical
1. Error loading example.jasper file - looks like the file is corrupted -- also
getting the error using IReport-nb-3.5.0
2. Replace file and code:
/**
* Constructor.
*/
Integer knt = 0;
public SimplePdfPage()
{
ServletContext context = ((WebApplication)
getApplication()).getServletContext();
// final File reportFile = new
File(context.getRealPath("/reports/example.jasper"));
System.out.println("About to get file , " + knt++ + "times");
// final
File reportFile = new
File(context.getRealPath("/reports/report1.jrxml"));
System.out.println(" gott file , " + knt + "times");
JasperDesign design = null;
try {
design = JRXmlLoader.load(reportFile);
System.out.println(" design -- created " );
} catch (JRException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//do something with template
try {
JasperReport report =
JasperCompileManager.compileReport(design);
System.out.println(" report -- created " );
} catch (JRException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
final Map parameters = new HashMap();
JRResource pdfResource = new
JRPdfResource(reportFile).setReportParameters(
parameters).setReportDataSource(new
ExampleDataSource());
System.out.println(" pdfResource -- created " );
add(new EmbeddedJRReport("report", pdfResource));
reportFile = null;
and now getting :
About to get file , 0times
gott file , 1times
design -- created
report -- created
pdfResource -- created
About to get file , 0times
gott file , 1times
design -- created
report -- created
pdfResource -- created
