jar problem

I'm struggling with a bug and am writing to see if someone has an idea
that
hasn't occurred to me.

I wrote some report generation software using Quest's JClass product.
It
produces a beautiful .pdf report as long as I run the code in Eclipse.
When
I create a .jar then run the .jar, it runs fine. But when I open the
generated report in Adobe Reader, it produces the error "invalid
restore".
I can view the report but the content of the tables are blank.

Because the code produces a valid .pdf in Eclipse, I know I have all
the
code necessary on my machine. However, when I create the .jar
something
goes subtly wrong. I've tried carefully checking all my classpaths,
etc.
I'm a bit concerned about Eclipse path filters.

Has anyone struggled with similar symptoms? If so, how did you resolve
it?

Thanks

the times I had a problem like this it usually was because I was using
different versions of some files, whereas I was thinking I was using the
same files. I remember once having a war file with two different
versions of the same class files. I know you carefully checked, but I
still think this is the most likely cause.
Anyway, besides checking again, I want to suggest to debug your jar (you
can do that with eclipse), and see what happens. I don't know if you did
it already, but even if you really made no mistakes you can more likely
find out what went wrong

I have not had this problem, but if I did here in what I would do.

Look in the eclipse working directory for the jars IT creates.

do a Jar -t myproject.jar to get a contents list.
Dump the manifest with winzip

Now do the same with the jar you created outside Eclipse.

Compare.
