Problems occured creating the new datasource! null
malleswari replied to malleswari's topic in Products
Well I found that, the "null" in the message just means its a null pointer exception while building data for the report. I made some changes to the JasperReports DataSourceProvider that started the problem. Post edited by: malleswari, at: 2006/10/18 21:29 -
I was compiling and running a report (that has subreports) just fine.. I added some fields to the report and suddenly it cannot run. It compiles just fine but gives the following message when I run it: "Problems occured creating the new datasource!! null" I removed the recently added fields. Doesn't help. I believe it does not have anything to do with the jrxml... Any thoughts why I might get this error ? Post edited by: malleswari, at: 2006/10/18 21:27

Yes, You should be able to do it. Add a duplicate of your object to the colelction you pass to: public JRBeanCollectionDataSource(java.util.Collection collection)

Hi, I am trying to place an image(detail band) right above the page footer. The attribute: positionType="FixRelativeToBottom" does'nt seem to work. Anyone knows why that would happen ? Or how to fix it ?

I have a report where margin space is important(atleast top margin). This report has a subreport whose margin space is also important(This subreport is also used by itself. So I cannot eliminate its margins). The margin space of the parent and subreport are adding up creating more margin space for subreport. 1) Is there any way to tell not to use margins for a subreport ? 2) Is there a way to specify in the parent report itself, specific portions where margins should nto be used (i.e. around the place where I place the subreport) ? I am using ireport for design. Post edited by: malleswari, at: 2006/08/02 14:58
