Error CSV master

[systemp]

Hi There,

I have generated a csv report using the ireport but for some my master report is getting alot of errors some times does not even display the report. I think is has something to do with REPORT_DATA_SOURCE.

what does this error message mean?

and how do i correcet it?

 

Secondly my master ireport on my other CSV source compiles well but does not show the data. Why is that so? I will appreciate any idea to solving this as it is important. PS : the master works well using an SQL report and a JDBC connection. but with CSV it does not work hmm:side:

Your stacktrace is signaling that it couldn't read an Object which was expected to be serialized and written at that location.

 

I don't know exactly why jasperreports is trying to read an Object out of a jrxml file but since you could get it working on a standard sql database why not forget about the csv solution?

Hi Isreal,

Thanks for the reply and the idea. I found a solution to my problem that worked well. Looking at old posted report on the discussion board from 2007 i realize some one has a similar problem and was never resolved. I think there is a trick to this since am calling an excel file converted to a CSV and running on ireport.Thus three thing to figure out.

All the same I got a better solution to my problem which sounds ok till I run in to something else.

This has to do with Pies -3D Charts

Question?? My CSV works fine and displaying all I wanted except that my charts keep showing the same information for different customers.

Does any one know how I could get it to read and draw/display each customer information without repeating the same value for different people??

will appreciate a feed back from any one.

Thanks

Stay great fellow
