Instal Zotero Plug-in for LibreOffice Without Installing Java

arsenk
Hello, I would like to know if there is a possibility to install the Zotero plug-in into LibreOffice Writer without having to install Java. I tried installing the Zotero plug-in, however, it asks for Java installation. Is there a way to put all necessary Java runtime files into necessary folders (or registry) and make Zotero work without installing java? I have also explored an option of a portable version, but naturally, Zotero doesn't refer to java runtime files in portable apps. Please help me sort out this issue. I know that it's possible to just install Java on the computer, but with recent security scares, I am hesitant to do so.
Thank you .

    You're confusing Java browser plugins, which are notoriously insecure and you should probably avoid installing, with just having a Java Runtime Environments installed, which by itself doesn't add much of a risk I'm aware of.
    But either way, the answer to your question is no -- LibreOffice extensions are (and have to be) written in Java, they can't run without JRE, so Zotero can't integrate with LibreOffice without a function JRE.

    Thank you for the response adamsmith. I think I will simply install the Java Runtime Environment on the computer, which will probably solve my problem. This might be a long shot, but what I was most interested in is the use of LibreOffice portable app. What I want to accomplish is to have:

    1) portable LibraOffice
    2) portable Firefox
    3) Zotero plug-in for portable Firefox

    Normally, portable apps have a Java Runtime folder which can be referenced during installation if necessary. I'd like to see if something can be done to install the Zotero plug-in inside portable Firefox without having to install Java Runtime Environment. Maybe change the path to whichever folder Zotero plug-in installation wizard looks at when during installation. Or maybe by adding a necessary registry key and a string.

    Thank you in advance.

    Keep in mind there is a portable JRE as well:

    Thank you for the response noksagt. That's exactly what I've downloaded to operate my LibreOffice and other portable apps. But, naturally, since it isn't installed on the computer, Zotero doesn't seem to see the necessary registry key or maybe the necessary folder in the system to initiate the Zotero plug-in installation. That's what I am trying to solve.
    I've even tried editing the registry by adding necessary keys into it. In addition to all, I have created a necessary java folder inside C:/....system32 and placed the Java Runtime Files from portable Java you've linked. Still no luck. :(
    I know that what I am trying to do is counter-intuitive, but there must be a way to do a standalone portable installation of the Zotero plug-in.

    Zotero just checks whether there's a JRE selected and enabled in LibreOffice. It doesn't look at the system registry (That's under Tools --> Advanced in LO, I believe).

    Thank you adamsmith. Ill give it a try and report back. Appreciate your thoughts on this.

    Gentlemen, unfortunately it didn't work. Don't know what else to do. Do you have any thoughts?

    I'd like to add that LibreOffice does see the Java Runtime Environment and it's checked in the settings. However, portable firefox plugin installation fails due to lack of Java.
