Thanks Uwe for your quick reply.

I got the the problem of setting classpath now.

But i have few question based on your reply. May not be related to the
topic of the thread.

Question 1 related to the point - *"In general it is not recommended to
install Solr inside a custom webapp container"*
where will solr runs in production environments? i was thinking that it has
to run on some web containers. Jetty is only for playing around/testing.
Please correct me if i am wrong.

Question 2 related to the point - "*Future versions of Solr may no longer
ship with a WAR file because it causes too many problems, because Solr does
not work well with other webapps in the same JVM"*
*
*
how can we use solr with any app say my own web app (typically, a spring
mvc or any EE app) if it is not shipped as war? Can't we use Solr for
solving problem of complex/advance search implementation (time consuming
search queries from RDBMS) that normally exists in any web app? say any
inventory management or warehouse management apps.

My requirement is for inputting data to reporting engine like
crystal/jasper and to generate analytic chars for our dashboards.

After seeing your reply, i started thinking that solr is not the one for
my requirement. Please clarify.

Thanks a ton.

Pradeep
