Hi!
Try to test python macro from https://extensions.xwiki.org/xwiki/bin/view/Extension/Python%20Macro:

{{python}}
print "Hello World"
{{/python}}

and got error:

How to use python macro?

os linux debian x64 10.2
pyhton installed 2.7.16-1, 3.7.3-1, default python2
xwiki version 11.10.2+1
java version openjdk-11-jre-headless 11.0.5+10-1~deb10u1

#2

Hi,

iā€™ve tested the Python code which you mentioned on a clean installed XWiki 11.10.2+1
on Ubuntu (from .deb-package).

Everything is working fine on a clean install.

The only difference (beside the the OS) is that i am using Java 8 instead of 11.

> java -version
openjdk version ā€œ1.8.0_232ā€
OpenJDK Runtime Environment (build 1.8.0_232-8u232-b09-0ubuntu1~18.04.1-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)

Is this a new XWiki install or have you upgraded from prior versions?

Best regards,
Dolo

Thanks for the test @Dolo.

I would not be completely surprised if Jython (the Java implementation of Python XWiki is using) has issues with Java 11. @amadis if you have a way to test your instance with Java 8 instead of Java 11 it would be very interesting. If it works by just changing the version of Java would be great if you could create an issue on https://jira.xwiki.org/browse/XWIKI about that.

XWiki embeds a Java implementation of the Python engine (Jython) so what the python version installed in your system should not matter I think.

Hi Dolo,

this is a fresh install

Hi Thomas.
I tested with java-8 - the same error.
Java-8 installed from https://adoptopenjdk.net/installation.html, described here
Tomcat9 was stopped, java-8 installed, update-alternatives not updated all alternatives, because java-8 has less priority, so I updated missed alternatives bu hand, /ett/defaults/tomcat9 was configured to the new JAVA_HOME, and after that tomcat9 was started. In log I got, that java-8 is used:

How can avoid this bug, but having page names in cyrillic?

From what I understand Jython does not like too much the fact that the script id (which is based on its location, so the wiki page here) contains UTF8 characters. It really looks like a Jython bug.

Would be great if you could create an issue on https://jira.xwiki.org/browse/XWIKI and indicate the cause of the failure.

The only workaround I can think of right now is to put the python macro in a document with latin characters only in its name. Maybe another possibility is to change the Jython JAR with the new beta but I donā€™t know yet if upgrading Jython require change on XWiki side or not (and assuming this bug is fixed in Jython 2.7.2 beta).
