Description Ulrich Windl 2018-02-28 15:01:09 UTC
When I try to install the Zotero extension for LibreOffice, installation fails with error "(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 } }". See https://forums.zotero.org/discussion/70628/zotero-extension-wont-install-
with-libreoffice-5-4-5-1-in-opensuse-42-3#latest
Where is the problem?

Try to execute the report in the database - JavaLoader couldn't be found.

Same behavior with Base-reports and
Version: 5.4.5.1
Build-ID: 40m0(Build:1)
CPU-Threads: 4; BS: Linux 4.4; UI-Render: Standard; VCL: kde4; 
Gebietsschema: de-DE (de_DE.UTF-8); Calc: group

If I try to execute a report a dialog appears with 
"could not find
com/sun/star/comp/Loader/JavaLoader"

So I will set these bug to Priority "Medium", because it's a bug of OpenSUSE-LO with the integrated extension ReportBuilder.

Note: Separate installations of rpm-packages directly from LibreOffice doesn't throw an error like this. They will execute the report.

It's the same as bug#1079744...

I am working on gnome desktop on my Dell laptop. I was trying to update LT extension in Libre Office 5.4.5.1, I get the following error:

"Error while installing extension LanguageTool. Open source language checker. The error message is: javaloader error - could not find class com/sun/star/comp/loader/JavaLoader
The extension will not be installed."

I have installed 'java-1_8_0'. It is working fine.
