Unable to access SOLR server admin page

I am new to SOLR. I am building SOLR from source using solr-5.0.0-src.tgz. After running

ant compile

at solr-5.0.0/, I run 

bin/solr start

at solr-5.0.0/solr/. And it says

Waiting to see Solr listening on port 8983 [/]  
Started Solr server on port 8983 (pid=20151). Happy searching!

However, when visiting http://localhost:8983/solr/, I receive HTTP ERROR

HTTP ERROR: 503
Problem accessing /solr/. Reason:
Service Unavailable
Powered by Jetty://

And

bin/solr status

gives

Found 1 Solr nodes: 

Solr process 20151 running on port 8983
Error: Could not find or load main class org.apache.solr.util.SolrCLI

I wonder if this is the reason admin page is unavailable? If so, how I could solve the problem. If not, what is it? Thanks.

To fix the problem you need to upgrade the java ...to J2SE 7

change to solr directory and run:

ant server

Then restart the server

bin/solr stop && bin/solr start

Check that everything is working:

bin/solr status
