RE: Tomcat 4.0.4, jndi, jdbc and postgresql [long]
The model is very simple and as a coder you never see that DBCP is there instead of Tyrex or a direct connection. Let me know how you get on an I'll patch the documentation accordingly. Also I noticed that my howto has made it into CVS (thanks guys!) so if you grab a nightly build (probably tomorrow now) then you can follow those instructions. Good luck!

Tomcat 4.0.4, jndi, jdbc and postgresql [long]
Hi
I've just started to write servlets. Servlets that only do processing, without
connecting to database work fine, but I have some problems to get the
connection with postgresql via jdbc work.
Tomcat: 4.0.4 (on linux)
Postgresql: 7.2.1 (on linux)
Jdbc: pgjdbc2.jar (from jdbc.postgresql.org)
The servlet is quite simple:
import java.io.*;
import java.util.*;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class InfoServlet extends HttpServlet {
Connection con;
private boolean conFree = true;
public void init() throws ServletException {
try {
Context initCtx = new InitialContext();
Context envCtx =
(Context)initCtx.lookup(java:comp/env);
DataSource ds = (DataSource)
envCtx.lookup(jdbc/BookDB);
Connection con = ds.getConnection();
} catch (Exception ex) {
throw new ServletException(Couldn't open connection
to database: + ex.getMessage());
}
}
public void destroy() {
try {
con.close();
} catch (SQLException ex) {
System.out.println(ex.getMessage());
}
}
public void doGet (HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
HttpSession session = request.getSession();
// set content-type header before accessing the Writer
response.setContentType(text/html);
response.setBufferSize(8192);
PrintWriter out = response.getWriter();
// then write the data of the response
out.println(html +
headtitleDuke's Bookstore/title/head);
}
}
in web/WEB-INF/web.xml I defined:

I've tried a few different driverName parameters: (restarting Tomcat after

jdbc:postgresql://localhost/public
jdbc:postgresql://full.server.name/public
jdbc:postgresql:public
jdbc:postgresql://localhost/
But, despite the parameters, I always get the following error:
exception

org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:918)
{cut}
I have no idea why Tomcat wants to connect using hsql driver. I grepped
through tomcat directory and found only one reference to this driver (in
examples section). I removed event the sample section, restarted Tomcat but
it didn't help.
Does anyone know what is wrong?

RE: Tomcat 4.0.4, jndi, jdbc and postgresql [long]
Two things,
In your server.xml
user I think should be username
and
driverName has been deprecated in favour of url which needs the servername
and DB name as well
(as in something like jdbc:postgresql://full.server.name/mybookdb - or
whatever the DB is called)
Are you *sure* you're using the right install of TC and that the server.xml
has no reference to the hsql driver?
BTW - only got this working with Oracle and mySQL so most of this is
guesswork based on those two exercises.
Bye,
Les
P.S. You shouldn't open the connection in init() nor cache the connection
BTW - use a pool instead :)

Do you have already connected to a postgresql db using a java app? Are you sure the
parameters are correct? What is public?
Where did you put the postgresql.jar?
Do you have a file named hsql.jar? Can you remove it?

Hi
I've just started to write servlets. Servlets that only do processing, without
connecting to database work fine, but I have some problems to get the
connection with postgresql via jdbc work.
Tomcat: 4.0.4 (on linux)
Postgresql: 7.2.1 (on linux)
Jdbc: pgjdbc2.jar (from jdbc.postgresql.org)
The servlet is quite simple:
import java.io.*;
import java.util.*;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class InfoServlet extends HttpServlet {
Connection con;
private boolean conFree = true;
public void init() throws ServletException {
try {
Context initCtx = new InitialContext();
Context envCtx =
(Context)initCtx.lookup(java:comp/env);
DataSource ds = (DataSource)
envCtx.lookup(jdbc/BookDB);
Connection con = ds.getConnection();
} catch (Exception ex) {
throw new ServletException(Couldn't open connection
to database: + ex.getMessage());
}
}
public void destroy() {
try {
con.close();
} catch (SQLException ex) {
System.out.println(ex.getMessage());
}
}
public void doGet (HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
HttpSession session = request.getSession();
// set content-type header before accessing the Writer
response.setContentType(text/html);
response.setBufferSize(8192);
PrintWriter out = response.getWriter();
// then write the data of the response
out.println(html +
headtitleDuke's Bookstore/title/head);
}
}
in web/WEB-INF/web.xml I defined:

Yes, without any problems from 'standalone' application. I'm able to query and
update database, so parameters (url, username and password) are ok.
There is no postgresql.jar, only pgjdbc2.jar. I put it in ${tomcat-root}/lib
directory. I tried first to add a link named postgresql.jar and then I've
renamed it but it didn't help :-(

I don't have such file.

RE: Tomcat 4.0.4, jndi, jdbc and postgresql [long]
Ok. Summary time.
Martin reflects my experience - I dumped tyrex and used DBCP as well. But
aren't we trying to go direct without a pool? Having said that I've only
ever managed to get datasources working when DBCP is being used...
Check that your driver jarfile does not contain the javax.sql extension
classes. If it does, delete them and rejar. Some versions of Tomcat will
ignore any jar that has these classes present. Be careful with this thought
- I work with jdk1.4 which has these built in.
Also, you don't specify a DataSourceFactory in your server.xml - see below.
Here's a known (well as far as I know...) good postgres solution using DBCP.
See

Re: Tomcat 4.0.4, jndi, jdbc and postgresql [long]
Hi,
I notice that you are doing the JDBC lookup in the init function. This
doesn't appear to work properly (at least on 4.1.6), move the initialisation
code to the doGet/doPost and see if that helps. This cured my JNDI/JDBC
problems.
Regards.

Re: Tomcat 4.0.4, jndi, jdbc and postgresql [long]
Neither adding description nor removing slashes helped. I've checked the path in manual: jdbc:postgresql:database jdbc:postgresql://host/database jdbc:postgresql://host:port/database This last form is the most complete one. Anyway, that will not make a difference, since it is up to JDBC driver to parse this URL AND JDBC DRIVER WORKS. I wonder if there is a way to debug what exactly Tomcat does. What section of server.xml does it parse etc. I've tried running Tomcat under JBuilder. I did get into debugging session, but when it came to XML parser, it just, sort of, dropped into a hole. I needed sources for XML parser, too. At that point I've had had too much and decided to wait for DBCP. Does anyone tried to connect to postgresql and succeeded? Craig has done it and although he is one of the developers, he was unable to help us. I guess it is not just for fashion, that they have decided to drop Tyrex in favour of DBCP. Nix.
