exec () does not execute the passed command

Navigation

I'm trying to use the exec() PHP function to execute a .jar file (I know it's not a good practice, but it's the only solution I have at the moment), but I'm not getting good results. >

The code in question: 

exec(java -jar /home/sistemas/relatorios/jasper_reports/NaturatinsJasperReports/NaturatinsJasperReports.jar 'SELECT * FROM ambiental.vw_fin_fua_ato_azul WHERE id_fua = 31968408 ' '/home/sistemas/relatorios/jasper_reports/jasper/memoria_calculo_azul.jasper' '/home/sistemas/relatorios/memoria_calculo_azul.pdf' '/home/sistemas/relatorios/jasper_reports/NaturatinsJasperReports/desenvolvimento.xml', $output)

I execute and simply get empty feedback. The variable $output is set with a Array and nothing else. However, the parameter-driven command works perfectly when executed via the terminal.

Does anyone have any ideas?

Thank you.

It may be the user's permission, basically you are running the web server with an X user, so you can only run programs and functions where user X has permissions.

Try changing the permissions of the file or the user that the server uses.
