title: how to add mysql jdbc connector in classpath
body: <p>I have upgraded to solr 3.6 to SOLR 4.0. i am using dataimporthandler to extract data from database. 
  I have copied mysql-connector-java-5.1.20-bin.jar into apache-solr-4.0.0-ALPHA/example/lib folder. </p>
  
  <p>I have also added it in classpath using cmd </p>
  
  <pre><code>export CLASSPATH=.:$JAVA_HOME/lib/classes.zip:/usr/solr4/apache-solr-4.0.0-ALPHA/example/lib/mysql-connector-java-5.1.20-bin.jar 
  </code></pre>
  
  <p>When i browse solr/admin page and click on java properties it shows all .jar files from solr-home/lib folder in java.class.path but doesnt add mysql-connector-java-5.1.20-bin.jar </p>
  
  <p>What will be the reason that mysql-connector-java-5.1.20-bin.jar not getting added in java classpath?</p>
  
  <p>let me know if i am missing anything.</p>
