"JavaLoader error" in LibreOffice extension

Schweineschwarte · February 9, 2018

Hello,
I work some time without any problems, with Zotero and LibreOffice.
Today, Zotero calls me, I should install the extension for LO, though I have it installed already.
The installation over Zotero failed (I don't know the exact message anymore :( ).
Now, I want to install the LO extension manually, so I delete the old Zotero extension with the LO extension manager, and want to add the Zotero extension "Zotero_linux-x86_64/extensions/zoteroOpenOfficeIntegration@zotero.org/install/Zotero_OpenOffice_Integration.oxt".
But now, LO calls:
(com.sun.star.uno.RuntimeException) { { Message = "javaloader error - could not find class com/sun/star/comp/loader/JavaLoader", Context = (com.sun.star.uno.XInterface) @0 } }

I have delete Zotero and unpack it again, but no improvement.

My system:
openSUSE 42.3 64 bit

Same problem here, Opensuse 42.3, I can see the Zotero toolbar in LibreOffice Writer, but it doesn't work, and I get the same problem when I try to reinstall

You should try installing JRE provided directly from Oracle and see if that helps.

No, it don't works.
I have installed the jre1.8 and jdk-9.0.4 parallel with the open-jdk, selected in the LO-options Oracle jre, and reinstalled Zotero-extension again. But no changes. After, I tested it with the jdk, but no changes, too.

I have the same problem, even with the updated version of Zotero and java, when reactivating the extension it keeps marking the same error.

My system:
openSUSE 42.3 64 bit
LibreOffice 5.4.4.2
Zotero 5.0.35
Oracle-Java 8u161
openJDK 1.8.0.151

I would try downloading the official version of LibreOffice and see if that makes a difference. There could easily be something different about the openSUSE version.

@dstillman
Yes, it works.
I have installed LO 5.4.5.1 from the official homepage parallel to the actual installed version and installed the Zotero-extension without any problems (new LO use open-jdk).

I will contact the package-builder.

He shows me the discussion on openSUSE-bugzilla:

Finalmente funcionó instalando la versión 6.0.1 de los repositorios de OpenSuse: https://software.opensuse.org/package/libreoffice
