Re: [Swftools-common] PDF2SWF conversion hangs when called by simple java program ..

[Luca Agostini]

I don't know if it's too late to respond. but i think swftools crashes because the stdout and stderr is not redirect to file or null (i don't remember if this is a know java bug).
I have many problems running script (with many echo) from java, but if I redirect output to null all it's ok..

I think you mix up two problems:

 

1)      Pdf2swf is call via cmd or C: works, but if called (same pdf) via java it hangs: This can be solved by properly using the java API as I already posted.

2)      Pdf2swf crashes and windows reports this via a dialog. This is a windows problem since the dialog is not shown by pdf2swf. For pdf2swf 0.9.0 if havn’t seen any pdf out of > 1000 which causes this so it should happen very rare. However you could used linux or unix or the like since a segfault there is handled without any dialogs. Or you need to figure out how to keep windows from showing this dialog.

 

Are you using pdf2swf 0.9.0 or the latest snapshot? The latest snapshot seems to be way more unstable than 0.9.0!

Hi

I already report the problem at http://lists.gnu.org/archive/html/swftools-common/2009-09/msg00096.html
still no solution. The workaround is to make scheduler with time-out then process will be killed after time-out in this case you need to catch it and execute it with poly2bitmap then you got swf it is a bit ugly swf but it works keep in mind that you need to split your pdf to single pages and execute it for all pages one by one.

I am still waiting for solution.

Regards
Farhad

That's not true at all, we call pdf2swf from java without any problems (we
converted about 800 documents with > 60.000 Pages) without ANY problems. All
you need to do is read stdout AND stderr of the called program.

I have attached a samnple Java-Class which does that.

Andy

Try running pdf2swf with the -vvvv option and determine the
last log statement before it hangs.

These "calling from Java" issues have come up before, but nobody
seems to have found a definite solution.
