No printer found error

2004-03-25 00:21

Hi all,

 

I met a problem when using JasperReport.

This is my code :

 

46. while (true) {

47. Thread.sleep(1000);

48. JasperPrintManager.printReport(jasperPrint, false);

49. i++;

50. System.out.println(i);

51. }

 

After loop about 1000 times, an exception will be thrown.

One of the output is as following:

 

1

2

3

Hi,

 

I don't think this is related to JasperReports.

You are trying to print a document 1000 times

in a loop.

Don't you think the spooler gets clogged, even if

it is about a virtual printer.

Try doing the same thing and print some other

document 1000 times.

 

I hope this helps.

Teodor

Hi,

I don't think this is related to the document.

 

The actual situation is we have an application programme responsible for

printing which is the APPLET embeded in IE. Users prints all kinds of

documents with this program ( APPLET), but after using for some time, IE

will come up against the problem of "invalid/illegal operation" .

 

We have excluded any other possibility and finally found that the error is

due to the JasperPrintManager.printReport(), and found the function has

memory leak.

 

It seems the

bug(http://developer.java.sun.com/developer/bugParade/bugs/4737016.html,

http://developer.java.sun.com/developer/bugParade/bugs/4657463.html)

of the jre has something to do with this problem. We have tried the

jdk1.4.2_04 but still can not solve the bug.

 

Supposed the error is really because of the jre, is there any other

function we can use to steer clear of it? or any other substitute

solutions?
