From PL/SQL call java class present in Application server

Question

Hi,
I need to call a java class file which is present on the application server. the call has to be made from pl/sql.
I do not want to make use of the java stored procedures for this.
Is there a way to call a class file residing on the application server from a pl/sql.
Please help me out.
Thanks & Regards

New idea. DDL isn`t working but if i would make some DQL ? Like select??
I`m trying to deploy java class like this:
public class test {
     public static String say()
          throws SQLException{
               Connection conn = new OracleDriver().defaultConnection();
               String sql = "Select names from pdb_proteins where numbers=61";
               try {
                    // Load the Oracle JDBC driver
                    Class.forName("oracle.jdbc.OracleDriver") ;
                    System.out.println("Oracle JDBC driver loaded ok.");
                    } catch (Exception e) {
                    System.err.println("Exception: "+e.getMessage());
               try {
                    ResultSet rset = null;
                    PreparedStatement pstmt = conn.prepareStatement(sql);
                    rset=pstmt.executeQuery(sql);
                    String wynik = null;
                    wynik = rset.getString(1);
                    return wynik;
          } catch (SQLException e) {
               System.out.println("Connection Failed! Check output console");
               e.printStackTrace();
               return "nope";
Then invoke with PL/SQL function
and i`m getting error ORA-29534: object SYSTEM.oracle/jdbc/OracleDriver
Could someone help me with this? How i could register jdbc driver inside Oracle db??
