Libreoffice can't find Java on ubuntu server

[maribov]

I’m trying to run the following command using Symfony inside of a controller that I have (laravel):

"soffice --safe-mode --convert-to pdf store/file.docx --headless

It works in commandline but not when run through the controller. I thought it might be a permissions issue at first but now I keep getting this error about java:

Exit Code: 77(Unknown error)↵↵Working directory: /var/www/project/public↵↵Output:↵================↵↵↵Error Output:↵================↵javaldx failed!↵Warning: failed to read path from javaldx↵LibreOffice 6.2 - Fatal Error: The application cannot be started. ↵User installation could not be completed. ↵"
trace: [{function: "getHigherPDF", class: "App\Http\Controllers\AssessmentController", type: "::"},…]

so I’m thinking that it can’t find java for some reason? Where can I update the path to my correct instance of java if that’s the issue?

When i do which libreoffice it says i’m using /usr/bin/libreoffice, but when i try to find a place to updat the java path in there I’m afraid to edit because it’s not super clear where the path is defined

edit: i’ve tried installing libreoffice-base and it didn’t help

Some questions, and no guarantee that answering them would help at all.

• Why --safe-mode?
• Why Java is needed at all? do you have Java-dependent plugins with your LibreOffice? otherwise, for a docx import and pdf export, there shouldn’t be a need for Java.
• How is LibreOffice installed? PPA? Snap? TDF DEB?

• I was attempting to use --safe-mode because of a certain thread I found where someone was having a similar error, but i get the same result without --safe-mode as well, it made no difference
• I don’t think I DO need Java, but I get this error even though all i’m running is the pdf convert. is there a way to have libreoffice stop looking for java completely?
• I installed it using ppa

@mike kaganski I see here that there is a way to turn off java for libreoffice through the gui, is there a way to turn it off via terminal if I’m running it on a remote server where I can’t have a gui? Can I use Libre Office without java?

How to disable Java in configuration files

Hi, I’m writing automated scripts to deploy LibreOffice to Red Hat hosts, and I’m setting various configuration options using xml files under /usr/lib64/libreoffice/share/registry. How can I disable Java in a similar fashion? (ie Tools → Options → LibreOffice/Advanced → Use a Java runtime environment). I need this option disabled and locked for all users. I’ve Googled around but I can’t seem to find the name of the option I need to disable.

Posted an answer a few days back to help resolve a similar error. Don’t know if it solved that problem, or if it’ll solve this one, but it might help… Can't run Libreoffice at all - Crash at the beginning

I had to give www-data the correct home directory!!

 $process = new Process("HOME=".getCWD()." && export HOME && libreoffice --headless --convert-to pdf store/mar_maribov_higher_results.docx --outdir store");
        $process->run();
        return $path_copy_pdf;
