But in JRXML I see the following - Since I am using MDX query in subdataset, it seems I should have "MONDRIAN_CONNECTION" parameter in connectionExpression. I have also gone through this link http://jasperforge.org/plugins/espforum/view.php?group_id=83&forumid=101&topicid=50644&page=1 But I didn't get how to pass MONDRIAN_CONNECTION Parameter to the subdataset. Can anybody tell me how to deal with this? Thanks in advance. Rajan Code:<crosstabDataset> <dataset> <datasetRun subDataset="dataset1"> <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression> </datasetRun> </dataset></crosstabDataset>
