net.sf.jasperreports.engine.JRException: Error loading object from InputStream error after loading report to jasperserver from ireport

Hi

I'm facing a strange problem.

I designed a report contains various nested subreports within it. After designing in ireport it is working propely in iReport, when I publish the same report to jasper server its working fine there too.

But when after publishing the report when I'm trying to run it in iReport again its giving error.

I modified the subrepot expression from "repo:subreport.jrxml" to "subreport.jrxml" in iReport but still its giving the same issue. I,m unable to figure it out why its giving this error.The report is same as privious.

Can anyone help me regarding this issue.

Thanks
