Subject Tomcat not recognizing JDB drivers - 4.1.29!-Please Help
Date Wed, 10 Dec 2003 12:25:13 GMT
Hi everybody,
 
   I'm really new to Tomact and I'm facing this problem. 


     I have put the classes in the package and Tomcat is now able to
recognize that. Now It is not recognizing the Oracle drivers which I have
them in C:\Jdbcdrivers as classes12.zip and added in CLASSPATH but When I
call it from jsp page , it is giving me error as :- 

        java.sql.SQLException: No suitable driver 

Could you please point me in the right direction as where it is expecting
thoose drivers. 

 -------My Jsp code is----- 

<%@ page import="java.sql.*" %> 
<%@ page session="true" %> 
<%@ page language="java" import="pkgclass.*" %> 
<jsp:useBean id="PV1" scope="page" class="pkgclass.UserLogin"/> 



<%-- Statements to stop caching at client site --%> 
<% 
        response.setHeader("Cache-Control","no-store"); //HTTP 1.1 
        response.setHeader("Pragma","no-cache"); //HTTP 1.0 
        response.setDateHeader ("Expires", 0); //prevents caching at the
proxy 
%> 

<% PV1.setSID("SDGT"); 
        PV1.setHost("dpwdev02") ; 
        PV1.setSID("drpd"); 
        PV1.setUID("crdbweb") ; 
        PV1.setPWD("crdbweb"); 
        String sres = PV1.amplogin(); 
        out.println("Msgback : "+sres); 

%>

-------------------------------------------------------- 
I'm attaching my class code with this mail but I think the problem is that
Tomcat can't recognize the drivers 


Thanks in advance for your reply..

Divya

I believe that you have to package your class ie boots.PVDatabase 
  
as I recall unpackaged classes are not valid

Hi All, 

       I am new to Tomcat so I would really appreciate if somebody could 
help me in this. 

I have Tomcat 4.1.29 installed on my windows 2000 machine. At the  same 
level as examples is in Tomcat path, I've created a directory called 
boots(this is my application directory.) and have a index.jsp under 
boots and a class called PVDatabase.class under C:\Program Files\Apache 
Group\Tomcat 4.1\webapps\boots\WEB-INF\classes directory where 
C:\Program Files\Apache Group\Tomcat 4.1 is my CATALINA_HOME variable. 

   I have modified server.xml to include the context boots there.  When 
I try to call this class from my index.jsp it gives me the following 
error. 


org.apache.jasper.JasperException: Unable to compile class for JSP

Looking forward to hear from you very soon.
