If you can confirm it is working correctly on master, I’ll backport it.

Hi Paul,
as far as I can see, the ticket got fixed only on master (2.16-SNAPSHOT) but the change did not get
backported to 2.15.x. Technically it’s still fixed, only not in the series you want to use (we cannot force
volunteer to perform fixes where you need them, only where they want to/have time to do them) 
The 2.16.x nightly build extension has the jar:
https://build.geoserver.org/geoserver/master/ext-latest/geoserver-2.16-SNAPSHOT-excel-plugin.zip
I’d add a comment in the ticket though, maybe someone will run a backport of that change
Cheers
Andrea

Hi,
it seems, that the same problem is back in the newest stable GeoServer 2.15.2.
I got the same exception when trying to do a getFeature-excel2007-request.
Adding the „commons-compress“-library fixes it.
Should I reopen the issue (https://osgeo-org.atlassian.net/browse/GEOS-9159)?
I can’t tell if the fix from the issue has ever worked, because I haven’t tested it since then.
Regards,
Paul

Hi Andrea,
I’ve created the issue: https://osgeo-org.atlassian.net/browse/GEOS-9159
Unfortunately I am not that experienced with the development. So maybe someone else can fix it.
Regards,
Paul

Hi Paul,
thanks for the report. I’d first open a ticket so that it does not get lost:
https://osgeo-org.atlassian.net/projects/GEOS/summary
In case you’re up to make a fix, I believe it would have to be done around here:
https://github.com/geoserver/geoserver/blob/master/src/release/ext-excel.xml
Cheers

Dear GeoServer-List,
I have just installed the recent GeoServer 2.15.0 with the „Excel-WFS Output Format“-extension.
When trying to do a getFeature-request with the „excel2007“-outputformat, I got this exception (the „excel“-outputformat worked fine):
Caused by: java.lang.ClassNotFoundException: org.apache.commons.compress.archivers.zip.ZipFile
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1285)
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1119)
It seems that the „commons-compress“-library is missing.
After downloading it (from https://commons.apache.org/proper/commons-compress/download_compress.cgi) and adding it to the „WEB-INF\lib“-folder, it is working.
Maybe you have to add the dependency to the Excel WFS Output Format-extension.
I am running the GeoServer in a Windows environment using Tomcat 9 and Oracle JDK 8.
Best regards,
Paul
