Hi,

I am using solr-6.4.0. I am able to install Solr, create a collection named "core1", index files using post command and also able to search for data from Solr through browser instance. I was using the following URL to access Solr: http://localhost:8983/solr/core1. Now when I am trying to access the above URL through eclipse, it gives the following error:

[main] ERROR SolrQuery - Generic Exception : Server at http://localhost:8983/solr was not found (404).

org.apache.solr.client.solrj.SolrServerException: Server at http://localhost:8983/solr was not found (404).

at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:402)

Exception in thread "main" java.lang.NullPointerException

at java.io.FileOutputStream.<init>(Unknown Source)
at java.io.FileWriter.<init>(Unknown Source)
at SolrQuery.main(SolrQuery.java:89)
here is the code I am running:

public HttpSolrServer getSolrConnection() throws Exception
{

HttpSolrServer solrServer = null;
try {
// configure a server object with actual solr values.
if (solrServer == null) {

solrServer = new HttpSolrServer("http://localhost:8983/solr/core1");
solrServer.setParser(new XMLResponseParser());
solrServer.setSoTimeout(5000);
solrServer.setConnectionTimeout(5000);
}

} catch (Exception exc) {
logger.error(" Exception in getting Solr Connection: "
+ exc.getMessage());
exc.printStackTrace();
}
return solrServer;
}
I used the same code with solr 4.5.0 and it was perfectly fine. but after upgradation its not working. please let me know what to update/include (jar files if any other). thanks

Thank you
