shell_exec error with libreoffice

Question

I try to exec the following command with php:

shell_exec('libreoffice --headless --convert-to pdf test.doc 2>&1');

and I get the following error:

[Java framework] Error in function createSettingsDocument (elements.cxx).
javaldx failed!
Warning: failed to read path from javaldx

This works:

exec('touch test1');

And on command line this also works (pdf is generated):

$ libreoffice --headless --convert-to pdf doc1.doc

is that a permission problem? How can I solve it?

Answer 1

Try to set an output path like:

exec('libreoffice --headless --convert-to pdf test.doc --outdir /YOUR/PATH/');

or you try something like this for your webserver user:

sudo -u www-data -c "export HOME=/tmp"
