Class Loader issues

Hi all,

I am trying to load Jackson json library from the solr-5.3.1/contrib/clustering/lib directory.
In solconfig.xml I have the following entry: <lib dir="/dev/solr-5.3.1/contrib/clustering/lib" regex="jackson-.*\.jar"/>

When I start solr, I get the following warning:
SolrResourceLoader

No files added to classloader from lib: /dev/solr-5.3.1/contrib/clustering/lib




The path is correct and regex should load jackson-core-asl-1.9.13.jar  and jackson-mapper-asl-1.9.13.jar  but it does not. Any help is appreciated.

Thanks,
Firas

Hi,

Do you have (execute) permission for /dev/solr-5.3.1/contrib/clustering/lib
?
I've seen same warning when I have not access permission to the library dir.

Regards,
Tomoko
