Invalid Stream Header Exception

2003-03-27 22:33

 

I am getting an "invalid stream header" exception when trying to execute the fillReportToFile() method. Is there any suggestion to fix this?

(I have tried specifying the complete path to the xml file - no success).

 

thanks,

John.

 

 

JasperFillManager.fillReportToFile("report.xml", new HashMap(), getConnection());

Ok I have realised the .jasper file must be used and not the xml file. However there is also another problem now:

 

java.SQL.SQLException: ResultSet is closed.

 

I am not sure why this is. I am using the Access odbc driver here and I have tested that the Connection object is not closed. So that's ok.

I do not have any Access tables open or anything like that. Any ideas?

 

Thanks,

John.
