package does not exists?

Hi , experts I downloaded some jarfiles for accessing as400 db2 database
and wheather  I run it as a jsp or when I edit it using NetBeans  as a servlet class it appears package does not exists,
"com.ibm.as400.access ", I just tried by using "import com.ibm.as400.access.*;" with same bad  results
With the   Net beans Ide I added the jar files as Libraries and when I check them out (the jt400 from inside) it shows up the full path completed

jt400.jar:
com
      ibm
            as400
                     access
                                as400JDBCDRIVER.class


but anyHoww when I want to compile it using net beans it shows class not found
(as400JDBCDRIVER.class) and if I import the com.ibm.as400.access.*; I get this error "package does not exists"

I downloaded the  jars and I put them in a folder I just called IBMJTOPEN(just a name) where I unzipped them at
I added the jars path to my class path
--------------------------------------------------------------------------------
%classpath%;C:\WINNT\java\Packages;C:\jakarta-tomcat-5.0.28\common\lib\servlet-api;C:\jakarta-tomcat-5.0.28\common\lib\jsp-api;C:\IBMJTOPEN\lib\jt400.jar;C:\IBMJTOPEN\lib\util400.jar;C:\IBMJTOPEN\lib\jt400Servlet.jar;C:\IBMJTOPEN\lib\util400.jar;C:\IBMJTOPEN\lib\jt400Servlet.jar;C:\IBMJTOPEN\lib\composer.jar;C:\IBMJTOPEN\lib\jt400micro.jar;C:\IBMJTOPEN\lib\jt400Proxy.jar;C:\IBMJTOPEN\lib\jt400Servlet.jar;C:\IBMJTOPEN\lib\jui400.jar;C:\IBMJTOPEN\lib\outputwriters.jar;C:\IBMJTOPEN\lib\reportwriter.jar;C:\IBMJTOPEN\lib\tes.jar;C:\IBMJTOPEN\lib\uitools.jar;

The code I use is :


try {
            DriverManager.registerDriver(new com.ibm.as400.access.AS400JDBCDriver());
                     conn = DriverManager.getConnection("jdbc:as400://" + system, username, password);
             DatabaseMetaData dbMetaData = conn.getMetaData();
             conn.close();

           
            }
            catch (SQLException e){System.out.println(e.getMessage());e.printStackTrace () ;}
            catch (ClassNotFoundException e){System.out.println(e.getMessage());e.printStackTrace () ;}
     
     return conn;
