Jasper Report导出崩溃

Question

I have a crosstab report that outputs 75 pages. When I do an export to Excel, after 2-3 mins, it crashes and says "An id is required to lookup a FlowDefinition".

The output of the query contains less than 100,000 rows and the query itself takes 25 secs to execute. (from Naivcat) After this, jasper server takes some more time to fill the report. But exporting does not work.

FYI - I have changed the Crosstab limit to 1000000 from the default 100000.

#limit the crosstab bucket/measure count to prevent out of memory errors
net.sf.jasperreports.crosstab.bucket.measure.limit=10000000

#suppress page and column footers and all but the first page and column headers when     exporting to XLS
net.sf.jasperreports.export.xls.exclude.origin.keep.first.band.1=pageHeader
net.sf.jasperreports.export.xls.exclude.origin.band.2=pageFooter
net.sf.jasperreports.export.xls.exclude.origin.keep.first.band.3=columnHeader
net.sf.jasperreports.export.xls.exclude.origin.band.4=columnFooter

# report exporter hints override export parameters
net.sf.jasperreports.export.parameters.override.report.hints=false

Thanks Ravi

Answer 1

It could be the browser dependency, I had the same issue then i ran the report in Google Chrome, now my report is working.

So I would advice check with Chrome or whatever you are using just try in other browser.

删除总页数，仅显示“ Page 1”而不是“ 75 of 1”-这将显着改善报告的生成，因为JR不需要重新评估每个页面来添加总页数。
