title: Configure SQuirrel SQL Client to work for DB2/AS400
body: <p>I use the ancient System i Navigator (french) to get to query a DB2 (AS/400) database.</p>
  
  <p>I liked to update the client and use a more fresh (and English) sql client for that database.</p>
  
  <p>So, I installed the <strong>SQuirrel SQL client</strong> (3.5.0, the latest at day).</p>
  
  <p>After the installation and launching, I discovered that the "IBM DB2 App Driver" is not "checked".
  The message when I click on it says: </p>
  
  <blockquote>
    <p>"Could not find class COM.ibm.db2.jdbc.app.DB2Driver in neither the
    Java class path nor the Extra class path of the IBM DB2 App Driver
    driver definition: java.lang.ClassNotFoundException:
    COM.ibm.db2.jdbc.app.DB2Driver"</p>
  </blockquote>
  
  <p>As I understood I need to copy a (universal?) JDBC driver in the SQuirrel "\lib" folder. How to get it? </p>
  
  <p>I don't have any "classpath" defined in the environmental variables (I am on Windows 7 x64). 
  I am not a Java developer, so I am not sure if I need or not to configure that classpath to make work that sql client.</p>
