Hii Tahir!!!

My problem is for generate the report in PDF format, the report is built in runtime, we don’t have a previous PDF.

We can’t reproduce this failure in others environments, just in Production Environment.

We going to create this simple Java Application and come back with you.

Thank you!

Gil Quintana.
