JasperReports very slow when loading JasperPrint file

[martins.tuga]

I'm loading JasperPrint file and it's taking about 2 seconds to load a 60KB file.

My code is:

String jpXML = .....;[/code]

InputStream is = new ByteArrayInputStream(jpXML.getBytes("UTF-8")); [/code]

JasperPrint jp2 = JRPrintXmlLoader.load(is); //This is taking 2 seconds[/code]

Does anybody know how to speedup this? The problem seems to be in the XML Digester...

Thanks

Try to use this way instead:

 

JasperPrint jp2 = JasperCompileManager.compileReport(JRXmlLoader.load(is));

Thanks for your suggestion, but i'm already loading a JasperPrint not a JRXML content, so I can't load it with JRXmlLoader.

Ok. One time I have noticed that report was slowly generated for the first time but repeated generations was faster.

And second I faced a problem with slow rendering of a report when it had element with position type=Fix relative to bottom, but it was a complex report.

PROBLEM SOLVED!!

 

The JasperPrint load felt from 2000 miliseconds to 10 miliseconds.

 

I've just updated this dependency from:

 

 <dependency>[/code]

    <groupId>xerces</groupId>[/code]

    <artifactId>xercesImpl</artifactId> [/code]

    <version>2.10.0</version>[/code]

</dependency>[/code]

 

 

 

To

 

 <dependency>[/code]

    <groupId>xerces</groupId>[/code]

    <artifactId>xercesImpl</artifactId> [/code]

    <version>2.11.0</version>[/code]

</dependency>[/code]

 

 

So there might be some performance issue with the version 2.10.0 of this lib.
