Thanks to Durham David , Shawn French, Michael Sebetich and Rich Fincher for prompt response. Looking at your feedback, i feel TOMCAT+SSL would be enough for me. If i need APACHE+TOMCAT+SSL , i can do it more easily in th next version of TOMCAT (which is in beta) which has a web interface for creating connection to APACHE (Otherwise which would be a tricky one like you pointed out) Thanks again Sujith -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

warp / jdbc problem
Hi, I'm having problems connecting to mysql from tomcat when (only when) going via the warp connector. (with roller in this example - I'm assuming it's not app specific) I point a browser to http://localhost:8080/roller/ and everything works - db access no problem. I point a browser to http://localhost/roller/ and I see the webapp html no problem, but I get the exception below whenever it tries to hit mysql. thanks in advance for any help on this (chunks of httpd.conf/server.xml versions at the bottom if they can aid diagnosis) rob.

RE: MaxProcesses in Server.xml
Hi, I am generating multiple threads on a client machine and am measuring how long would it take for the thread to finish after it gets serviced from the tomcat server(I am calculating the difference in time). I figured that much ;) The reason I was asking is that it is sometimes difficult to determine exactly how long a request takes to complete, especially if it's relatively short, e.g. a few seconds as in your case. I've seen people use everything from stopwatches to sand clocks to measure this. I was wondering if you were using a specific tool to get these measurements?

Re: howto avoid overuse of session object?
Thanks, Cédric and Peter Lin, for your responses. Both of you seem to be saying that, instead of storing large objects in the session object, I should be storing them in the application object (ServletContext). ServletContext is not application context (yes, there is an application context, too). If you need objects saved between requests, during one session then session has to have enough information to save the state. If you're not going to pack all the state in the current session (I'm not sure why is this a bad idea), then your other option is to pack that some place else and just store some ID in the session. Whether you're packing single beans in hierarchically higher contexts or you place them into a database (via JDBC) or create EJB (an overkill and misuse, I'm sure), you still end up saving that information somewhere. So, somewhere it will fill up memory, buffers, disk, whatever. I cannot fathom why it is better to load piles of objects into higher contexts and have to worry about identifying them and cleaning up after expired sessions, than having them in session context. I find this to be rather confusing. It seems like the overhead involved in storing things in the application object would be much greater than storing things in the session object. Same here. At least the session objects would eventually die when ssions time out or they are invalidated by the web app, and the space they re using could then be garbage collected. But the application objects would live as long as the server is up, and I would think would eventually consume memory moreso than using the session would. You would have to implement session cleanup via some Listener (SessionListener or some such class). Basically, you'd be emulating something like dispersed session context, with parts of a particular session held elsewhere. Ugly, nasty, not to mention slow. IMHO. Also, there would be a extra level of complexity involved with maintaining the association between the objects in the application object and their respective sessions. Am I unclear on the concept, or is there something else that I'm not understanding? Would someone enlighten us. Why is session context so dreadful that we should avoid it? I agree we should minimize it's use, but minimization is not avoiding the use. Nix.
DB2 and servlet ??? Help !!!
Hello everyone...
I am trying to connect the run a simple servlet to retrieve the
query results from DB2 database.
1. Before writing a servlet, I wrote a simple java file and was successful
in retrieving the
contents from DB2 UDB.
2. Then I just converted the same JAVA file into servlet by adding Servlet
API and syntax in it.
3. It compiles fine.
4. Then from a web page I try to pass one parameter to my servlet.
5. The servlet doesnot retrieve any records from the database which
initially it was bringing
when I wrote simple java file.
Code of my servlet is as:
--
import java.sql.*;
import java.lang.*;
import java.io.*;
public class Ndb2Tomcat{
public static void main(String args[]) {
try{
Class.forName(COM.ibm.db2.jdbc.net.DB2Driver);
}
catch( ClassNotFoundException e2)
{
System.out.println(\nJDBC Driver class not found exception);
}
catch( Exception e)
{
System.out.println(\nDriver class not found exception);
}
try{
Connection con = null;
String url = jdbc:db2://100.3.13.34/SAMPLE;
con = DriverManager.getConnection(url,db2admin, db2pwd);
// retrieve data from the database
System.out.println(Retrieve some data from the database...);
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(SELECT * from db2admin.employee
order by firstnme);
System.out.println(Received results:);
while (rs.next())
{
String a = rs.getString(1);
String str = rs.getString(2);
System.out.print( empno= + a);
System.out.print( firstname= + str);
System.out.print(\n);
}
rs.close();
stmt.close();
con.close();
}
catch (SQLException e1)
{
e1.printStackTrace();
}
}

RE: Tomcat 4 Suse 8
I am running TC4.0.4 on SuSE 8.0 without problems. --JG -Original Message- From: Januski, Ken [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 01, 2002 5:25 PM To: Tomcat Users List Subject: RE: Tomcat 4 Suse 8 Steve, I know it's possible. I mainly run Tomcat on W2K right now but have also experimented with it on Suse 8.0. Unfortunately I must have screwed something up because it's no longer working. But I'm sure I did have it working for awhile, nothing sophisticated but at least I know it can work. Sorry I can't give you much more info than that.
