JRFileVirtualizer and temporary files

We have implemented JRFileVirtualizer and are wondering:

How do you name the temporary files (written to the temporary directory) so that 2 or more users do not collide while filling reports simultaneously? Do you ever have a file called ".dummy"? as a temporoary file?

Maybe you can use java.io.File.createTempFile() method.
Look in javadoc for parameters.

Hope it helps.

I believe that the name of the output class file is derived from the name of the report <jasperReport
name="AssetInventoryReport" ... We append a unique jobID to the report name, so the generated java class file has a unique name (AssetInventoryReport5443), and I think the page files from the virtualizer use this name. So can you rename the report before compiling and filling it?

I'm not sure everybody is talking about the same thing here. The initial post said something about the virtualizer temp files and then the discussion switched to the temp Java file created when compiling report templates.

Either way, I don't understand what the problem is, if ever.

Thank you,
