JRViewer works slow when report is large

[blosser]

My result report contain crosstab which had about 100.000 cells. When I use scrolling in JRViewer all report works slow. One of the decision is generate report into pdf, but I want to use JRViewer. I consider, JRViewer represent all cell as java components. I want to try represent report in JRViewer as Image and think it will be works faster in lagre report. How can I do it?

See this bug.

 

The fix of the bug consisted of a configuration property that determines when buffered images are used to render a report page in JRViewer, and a performance enhancement for the "direct" report rendering method.

 

You can get the latest source from SVN and test whether this fix can improve the JRViewer performance in your case.

Thanks for answer, lucianc.

I try to set property in my application, but result the same

Code:

System.setProperty("net.sf.jasperreports.viewer.render.buffer.max.size","10000000000000000000"«»)

 

What I do wrong?

[lucianc]

Firstly this property is a Java long property, and 10000000000000000000 is a little too much for a long value (max is 9,223,372,036,854,775,807).

 

Secondly, this should not be a system property, but a JR property. You need to do

Code:

JRProperties.setProperty(JRViewer.VIEWER_RENDER_BUFFER_MAX_SIZE, "1000000000000000000"«»);

instead, or put

Code:

[code] net.sf.jasperreports.viewer.render.buffer.max.size=1000000000000000000

in your jasperreports.properties (which should be placed on the classpath).

[lucianc]

The bug I was telling you about was fixed after the 1.2.7 release. That's why I told you to get the latest sources from SVN.
