title: Teradata and JDBC driver - classnotfoundexception ...but its there?
body: <p>Trying to work with a JDBC connection to Teradata.  I've loaded the tdgssconfig.jar and terajdbc4.jar file and adding them to the classpath with javac when I compile in Linux.  But I still get a ClassnotFoundException when trying to compile. </p>
  
  <p>I've not worked with java in a while, but I've scoured the net and it looks like it should work.</p>
  
  <p>Simple Code:</p>
  
  <pre><code>import java.sql.*;
  class TDtest {
      public static void main(String[] args) {    
          System.out.println(classpath);
  
          Class.forName("com.teradata.jdbc.TeraDriver");
      }
  }
  </code></pre>
  
  <p>*.jars are definitely there:</p>
  
  <pre><code>[user1@box java]# ls -l /home/user1/test/java/libs/*
  -rwxrwxrwx 1 user1 user1 2405 Oct 26 12:00 /home/user1/test/java/libs/tdgssconfig.jar
  -rwxrwxrwx 1 user1 user1 873860 Oct 26 12:00 /home/user1/test/java/libs/terajdbc4.jar
  </code></pre>
  
  <p>verbose error log - it looks like the classpath is right to me:</p>
  
  <pre><code>javac -verbose -cp ".:/home/user1/test/java/libs/tdgssconfig.jar:/home/user1/test/java/libs/terajdbc4.jar" TDtest.java

  <p>I've tried un-jar'ing the jdbc jar's and they definitely have com/teradata/jdbc/TeraDriver.class in them.</p>
  
  <p>I'm at a loss.  Any idea what I'm doing wrong?</p>
