it been days that I am trying to find a solution to start Solr 5.2.1 properly, but I always get this error :
HTTP ERROR 500
Problem accessing /solr/. Reason:
Server Error
Caused by:

Do you have any idea about it ? Thanks a lot !
Update :
Whene I check the solr sevice status :
service solr status
I get this too :
Typically, this indicates a problem with the Solr server; check the Solr server logs for more information. at org.apache.solr.util.SolrCLI$SolrResponseHandler.handleResponse(SolrCLI.java:502) at org.apache.solr.util.SolrCLI$SolrResponseHandler.handleResponse(SolrCLI.java:492) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:222) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:164) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:139) at org.apache.solr.util.SolrCLI.getJson(SolrCLI.java:527) at org.apache.solr.util.SolrCLI.getJson(SolrCLI.java:471) at org.apache.solr.util.SolrCLI$StatusTool.runTool(SolrCLI.java:659) at org.apache.solr.util.SolrCLI.main(SolrCLI.java:215)
