UTFDataFormatException

Has anybody else seen this when running reports on a platform other than the one that they were originally compiled?

Thats my exact problem, has anyone a solution for this?? I don't understand whats wrong!! Do I really have to recompile the all jasper files??

Can you upload a .jasper file that fails to load?

That file was created on a Mac and now I am testing the application on a windos werver, I have the jrxml of some reports but I wouldn't want to create the templates for all the reports that don't (have only the jaspers not the jrxml) .When I compile them on windows they work, but as I said some reports I have only the .jasper files.

 

Thanks in advance.

The first thing to check is whether the file somehow got corrupt, that's the most likely explanation of the error.  That can happen when trasferring file over the network, saving them in a DB, etc.

Do you still have the originally created file?  If so, take a MD5 (or similar) sum for both the files and see if they match.
