That certainly looks like it ought to work. Is there log output that you could
show us as well?

Hi,
I have downloaded the code and documentation for Solr version 4.10.3.
I am trying to follow SolrJ Wiki guide and I am running into errors. The
latest error is this one:

This is an example of a simple "solr.xml" file for configuring one or
more Solr Cores, as well as allowing Cores to be added, removed, and
reloaded via HTTP requests.
More information about options available in this configuration file,
and Solr Core administration can be found online:
http://wiki.apache.org/solr/CoreAdmin
-->
<solr>
<cores adminPath="/admin/cores" defaultCoreName="db">
<core default="true" instanceDir="db/" name="db"/>
</cores>
</solr>
And my db/conf directory was copied from example/solr/collection/conf directory
and it contains the solrconfig.xml file and schema.xml file.
I have noticed that the documentation that shows how to use the
EmbeddedSolarServer is outdated as it indicates I should use
CoreContainer.Initializer class which doesn't exist, and container.load(path,
file) which also doesn't exist.
At this point I have no idea why I am getting the No such core error and I have
googled it and there seems to be tons of threads showing this error but for
different reasons, and I have tried all the suggested resolutions and get
nowhere with this.
Can you please help?
Regards,
Joe
