Hi,

we have developed an application (using Netbeans) which in one windows is asking some parameters, reading some data from Oracle database and creating an xlsx worksheet on client side.

Everything is working fine but we have only one user (among 20 using our application) which has a problem. When the application has to start creating the xlsx file it hangs, the file is not even created on client side. This happens only on one specific machine

We cannot reproduce this behavior in our development environment or in any other machine.

I have tried to create an xls file instead of xlsx (using HSSFWorkbook instead of XSSFWorkbook) and the problem is not shown in his laptop. So the behavior seems to be related specifically to that problem. Apache POI library used is 3.11.

Is there any way to trace on client side (no administrator rights unfortunately on that machine) and see exactly what is causing this problem only on this machine?

Note that only JRE is installed on that machine.

Regards.

Alberto
