Stop littering the code with useless try/catch blocks. Use only one block
without any finally. Place a doc.add(new Paragraph("hello")) somewhere to
make sure that you are producing at least one page. I after this you don't
get any meaningful result then try with other machine.

Hi,
So, I followed your advice Here is what I had now:
------------------------------------------------------------------------
------------------
try {
...
Log..."Start Open"
try
{
doc.open();
}
catch (Exception e)
{
Log..."Printing Stack Trace for doc.open"
e.printStackTrace();
}
Log..."End Open"
... (Manipulation of Document)
Log..."Start Close"
try
{
doc.close();
}
catch (Exception e)
{
Log..."Printing Stack Trace for doc.close"
e.printStackTrace();
Log..."Printing exception info: "+e.toString()
}
Log..."End Close"
}
catch (Exception e)
{
Log..."Printing Stack Trace for overall method"
e.printStackTrace();
}
finally {
Log..."Finaly Block"
try
{
pdfWriter.close();
}
catch (Exception e)
{
Log..."Printing Stack Trace for pdfWriter.close"
e.printStackTrace();
Log..."Printing exception info: "+e.toString()
}
}
Output:
------------------------------------------------------------------------
------------------
Start Open
Finaly Block
Printing Stack Trace for pdfWriter.close
Printing exception info: ...
------------------------------------------------------------------------
------------------
So, this is really strange because it did not continue with execution
after the doc.open() call and yet it still somehow jumped to the finally
clause skipping the rest of the logic and not throwing an exception when
the open() call was called. I am a little confused at what is going on.
Please, let me know if you can sort out exactly the behavior that is
taking place.
Thanks,
Dave

Try it with the code I proposed, don't complicate. Also make sure that
you
add something to the page like a doc.add(new Paragraph("hello")) after
open.
