'No cores Created' in Tomcat while using Solr -


i'm working on large e-commerce site containing 200k products based on asp.net mvc3(c#). better performance of site search feature, i've decided use solr search. i'm new in solr , tomcat 7. i've googled , found this link , followed it.
when replacing schema.xml existing,i got error below

http status 500 - severe errors in solr configuration. check log files more detailed information on may wrong. if want solr continue after configuration errors, change: false in solr.xml ------------------------------------------------------------- org.apache.solr.common.solrexception: no cores created

what problem?am doing wrong or what?

in log, can find following line:

caused by: java.lang.numberformatexception: input string: "ma147ll/a"

that means, application tried parse schema.xml file , expects number in field contains string "ma147ll/a" @ moment. search file string , check documentation find out, wrong value.
