Then I will get the error message "Error while creating report".
After some investigation, I find it's failed because of the inclusion of some packages.
Then I divided the referred application jar packages into two groups. And run the report ant task separately for them. Surprisingly, it's working this way and generated two reports.
However, even if it's working that way, I still need to generate a single report by referring all the jar. packages together.
And also wondering what could possibly lead to this issue?
