I'm trying to embed JRBeanJavaCollectionDataSource in jrxml. I want to display table. In jrxml I wrote: <datasetRun subDataset="Table Dataset 1"> <dataSourceExpression> <![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($V{project})]]> </dataSourceExpression>`</datasetRun>[/code]$V{project} must contain javaCollection. I don't know how to write multiple line java code in variable expression in IReport 4.5 to get my javaCollection.It is possible? Or there is another way to get javaCollection
