In debug ok, but in real-time nothing

[yurish]

I'm generating reports with runReportToPdfStream method. When i'm debugging, everything is ok, but when i'm just executing my code, i can't get my report(The page cannot be displayed). I discovered, that this thing happens, when my report is very small(4 kB ). Any suggestions, what that might be? With large reports everything ok.

 

Looks like code in streaming is executing before report runs.

 

Code:

jasperDesign = JRXmlLoader.load(jrxmlDir+jrxml);
JasperCompileManager.compileReportToFile(jasperDesign,fileName);
InputStream fileStream =new DataInputStream(new FileInputStream(fileName));
		JasperRunManager.runReportToPdfStream(fileStream, servletOutputStream, map, dataSource);
servletOutputStream.flush();
		servletOutputStream.close();
		fileStream.close();
		File file = new File(fileName);
		file.delete();

 

variable filename is .jasper file.

 

Help? :blush: :unsure: :unsure:

Forgot to mention, no exception is there. Using 1.4 java, jasperreports 1.2.8 and struts framework.

Tried to close filestream before i'm closing outputstream. Seem's logically. And works fine. Don't know how it would be in future. But now works. Thanks anyway. =] ;)

Problem still on air. Any suggestions?

It is strange, but when i added Thread.sleep(1000); in to my code after runReportToPdfStream, everything works. Why do i need to give system some time, when i have very small reports?

Which browser are you using? Does the same thing happen if you write a small (static) PDF file to the response, instead of exporting a report?

Thank's for reply, Lucian!

 

I'm using IE6, but in firefox2 there is the same problem. While writing small static PDF in response, problem doesn't exist.

Is there a way we could reproduce this? I'm afraid determining the cause of this behaviour is impossible given the currently available information.

I don't know how to reproduce this. Now i set

Code:

Thread.sleep(1000) to my code. Everything is fine. Mb some king of bug, cause i'm not using the last version of JasperReports. Now it is fine. 

 

Conf of our application is:

 

Java 1.4.2

Struts Framework 1.1

Jasperreports 1.2.8

iReport 1.2.8

IE6
