[OFF-TOPIC]Yoav -- RE: Some pretty basic Tomcat Connection Pooling Questions????
Hi Yoav and all,
- Hold the connection for as little a time as possible. That is, get it
from the pool, use it, and return it to the pool as soon as possible.
- That means you don't get the connection in a servlet init() method and
return it in a destroy() method. That's too long a time to hold
connections usually.
- Always return connections to the pool. Typically, this is done in the
finally clause of a try/catch block to ensure it is executed even if the
JDBC operation fails.
- You create your pool once, preferably when the app starts up, and you
close the pool itself once, preferably when the app shuts down. A
ServletContextListener is good for this purpose. Make sure you close
the pool.
- Servlets and other classes use the pool as needed. You don't have to
use a one connection per servlet design (in fact those usually don't
work in the real world).
I've been using connection pooling via an init() method.
Above you say that one should avoid that.
So now I have put the connection code inside the method that actually
does the database work and dispensed with the init() method.
Before I made this change I didn't have a conn.close() statement or a
finally clause anywhere either (I DID have resultset.close and
statement.close()).
Now I have added a conn.close() statement after each database
interaction has been completed.
Both versions of the code work.
Would you say the it is optimised after having gotten rid of the init()
method?
this is the code in it's latter version:
~~~
try { //establish the connection
Context ctx = new InitialContext();
if(ctx == null) {
throw new Exception(No Context);
}
DataSource ds =
(DataSource)ctx.lookup(java:comp/env/jdbc/mb);
if(ds != null) {
conn = ds.getConnection(); //conn is a global variable
if(conn != null) {
message = Got Connection to DB + conn.toString();
}
}
} // end try block
catch(Exception e) {
e.printStackTrace();
}
try { //carry out the database query
Statement stmt = conn.createStatement();
ResultSet rst = stmt.executeQuery(select * from category where
categoryname not like '%Timetable%';);
while(rst.next()) {
Category c = new Category();
c.setCategoryName(rst.getString(categoryname));
clBean.addCategory(c);
} // end while block
rst.close();
stmt.close();
conn.close();
} // end try block
catch(Exception e) {
}
~~
Appreciate your help,
kind regards,
Luke

Hi Sorry, I haven't read the whole treads, but: Before I made this change I didn't have a conn.close() statement or a finally clause anywhere either (I DID have resultset.close and statement.close()). Never never do that. If you do not call connection.close(), the connection is NOT returned to the pool. So ALWAYS close(). (Maybe you are lucky and there are some special precautions of the pool driver, that make this work, but most drivers do not.)

Question about multiple instances instead virtual hosts
Hello, Now I have a production server with tomcat 4.1.24. I have several applications installed (in webapps) and sets them up as virtual hosts. I get the idea that using multiple instances would work better for me. I read the documentation but what I read is there are 2 possible solutions: for each instance install a new Tomcat installation and second modify the CATALINA_BASE directory. Now my questions: How could I best setup the multiple instances?? And second question is: my Tomcat webserver is standalone. That means handles all the http requests to port 80. How can I make this work with more than one instance?? In other words how do I establish that a http request (port 80) will go to the right Tomcat instance??

RE: [OFF-TOPIC]Yoav -- RE: Some pretty basic Tomcat ConnectionPooling Questions????
Hi,
I'd say your new version is much better designed and significantly more
scalable than the old, yeah.
But you went a bit too far: the DataSource lookup is potentially
expensive. That you can do in the init() method and keep a reference to
the DataSource, because keeping that reference doesn't use a connection
resource.
Then in your servlet methods, get a connection from the DataSource, use
it, and release it.
In your servlet destroy method, null out your DataSource reference.
So the DataSource lookup is done once, the DataSource reference is kept
as a private non-static member variable of the servlet class, and the
Connenctions are used only within methods, they're not class member
variables.

Subject: [OFF-TOPIC]Yoav -- RE: Some pretty basic Tomcat
ConnectionPooling
Questions
Hi Yoav and all,
- Hold the connection for as little a time as possible. That is, get
it
from the pool, use it, and return it to the pool as soon as possible.
- That means you don't get the connection in a servlet init() method
and
return it in a destroy() method. That's too long a time to hold
connections usually.
- Always return connections to the pool. Typically, this is done in
the
finally clause of a try/catch block to ensure it is executed even if
the
JDBC operation fails.
- You create your pool once, preferably when the app starts up, and
you
close the pool itself once, preferably when the app shuts down. A
ServletContextListener is good for this purpose. Make sure you close
the pool.
- Servlets and other classes use the pool as needed. You don't have
to
use a one connection per servlet design (in fact those usually don't
work in the real world).
I've been using connection pooling via an init() method.
Above you say that one should avoid that.
So now I have put the connection code inside the method that actually
does the database work and dispensed with the init() method.
Before I made this change I didn't have a conn.close() statement or a
finally clause anywhere either (I DID have resultset.close and
statement.close()).
Now I have added a conn.close() statement after each database
interaction has been completed.
Both versions of the code work.
Would you say the it is optimised after having gotten rid of the init()
method?
this is the code in it's latter version:
~~~
try { //establish the connection
Context ctx = new InitialContext();
if(ctx == null) {
throw new Exception(No Context);
}
DataSource ds =
(DataSource)ctx.lookup(java:comp/env/jdbc/mb);
if(ds != null) {
conn = ds.getConnection(); //conn is a global variable
if(conn != null) {
message = Got Connection to DB + conn.toString();
}
}
} // end try block
catch(Exception e) {
e.printStackTrace();
}
try { //carry out the database query
Statement stmt = conn.createStatement();
ResultSet rst = stmt.executeQuery(select * from category
where
categoryname not like '%Timetable%';);
while(rst.next()) {
Category c = new Category();
c.setCategoryName(rst.getString(categoryname));
clBean.addCategory(c);
} // end while block
rst.close();
stmt.close();
conn.close();
} // end try block
catch(Exception e) {
}
~~
Appreciate your help,
kind regards,
Luke

RE: Can session time be modified at runtime?
Hi, Why don't you investigate the cause for your timeouts instead of jumping through hoops to apply band-aids? ;) Consider an HttpSessionLister to track your sessions in a portable manner.

RE: Help - Newbie questions - where are the uploaded files stored ?
Hi, Both this and the original poster's intent are pretty bad as far as portability goes. First, instead of re-inventing the wheel, use a good and proven componet for upload handling, like commons-fileupload (http://jakarta.apache.org/commons/fileupload/using.html). Second, know that the Servlet Specification guarantees only one place where you can write files: the directory accessible via (File) getServletContext().getAttribute(javax.servlet.context.tempdir). If you want another directory, set it as an init-parameter to your upload servlet or your servlet context, or maybe even a JNDI Environment reference. Don't rely on the concept of current working directory as that's wildly different from one server implementation to another, and it's highly insecure.

RE: Question about multiple instances instead virtual hosts
To bind a IP to an engine have a look at either:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/host.html
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/host.html
For the installation structure:
First:
Have a look at RUNNING.txt in the tomcat distribution
...
Second:
We have a structure like this:
/usr/local/java/jdk/ibm1.3
/usr/local/java/jdk/sun1.3
/usr/local/java/jdk/sun1.3.1
/usr/local/java/jdk/sun1.4
/usr/local/java/tomcat-4...
/usr/local/java/tomcat-5...
/www/online/site
/log
dirctory for the log file
/conf
web.xml
server.xml
and other files that contain the site specific setup for tomcat
(tailored versions of the files that are provided by
tomcat)
make shure that the combination of IP and port are unique for
each instance of tomcat.
...
/work
Directory where tomcat stores the generated files and classes
/webapps
Directories for the contexts
/bin
start.sh
Script that calls the tomcat version that we want to use for
this site with the environment for this site:
JAVA_HOME=/usr/local/java/jdk/sun1.3.1
CATALINA_HOME=/usr/local/java/tomcat-
CATALINA_BASE=/www/online/site
export JAVA_HOME CATALINA_HOME CATALINA_BASE
${CATALINA_HOME}/bin/startup.sh
This way we can have different versions of tomcat at the same time,
all sites that use the same tomcat version use the same 'executable'
but different processes and individual configuration. If we want to
use an other version of tomcat we just have to change CATALINA_HOME
in start.sh (unless the config files are incompatible between these
versions)

basic FORM-based authentication failing
Hello all I have been trying to set up FORM based authentication, but it only works half-way. When I try to get to the protected resource, it sends me to the login page: good.

Re: Question about multiple instances instead virtual hosts
One reasonably strait forward way is to have a different startup script for each host.. The tricky part comes when you need to start them all up (nothing another shell script cant deal with). export JAVA_HOME=/opt/jdkversion export CATALINA_HOME=/opt/tomcat-4.1 export CATALINA_BASE=~/tomcat/webapps This would be a config suitable for a user how wants tomcat running in his/her home dir.. ~/bin/tomcat.sh ~/tomcat/conf/server.xml ~/tomcat/webapps ~/tomcat/logs ~/tomcat/tmp If you restrict the user's bash profile and symlink the binaries required to fire tomcat and the tomcat start stop script itself. The other alternative if you are hosting a number of sites but not letting other users start and stop tomcat is to have separate startup scripts in your rc.d directory or perhaps /Library/StartupItems on osx, dont ask me about windows as i think its silly (at least in terms of running java hosting). And you can simply run them all as a single tomcat user. The server.xml's need to be different for each host, the jk port numbers are the biggest admin hassle. But this is how you have all hosts connecting to port 80.. This involves mod_jk apache and such like, there are plenty of postings in the archives on this. IMO stick to jk1 , I have jk1 and 2 running, and 2 involves more configuration hassles.

RE: DBCP Performance?
Hi, The initial connections can be closed if idle, depending on your pool configuration, so you might be creating new connections each time even with the pool. Check your minIdle setting. If you're creating a new connection each time, a tiny bit of overhead can be expected for a pool over a direct DriverManager call. But that defeats the purpose of pooling. If your pool is properly configured and has a connection waiting, it should be a little bit more than a hash lookup to return the connection, which would be significantly faster than creating a new one.

Re: tomcat as AJP frontend to other tomcats?
Tore, We have a somewhat similar configuration. By configuring workers in your main Tomcat, you can redirect your client1, client2,... clientN contexts to other tomcat servers via AJP13. The Tomcat documentation has some decent examples of how to configure this (at least in 3.2.4 which is what we are using). We started out with a worker for each client but this is not scalable as your # of clients grows. The first problem is that when you configure a new worker you need to restart your main Apache/Tomcat server to recognize the new worker -- this means that your entire system is down, at least momentarily. More importantly, if you are directing each context to a single instance of Tomcat (i.e. you have a separate instance of Tomcat for each customer) this quickly becomes an inefficient use of resources. We ended up having over 50 workers redirecting to an equal # of Tomcat instances spread across 10 machines; this was not at all scalable. We ended up redesigning our system and in the process converted it to a shared model in which an arbitrary number of customers share use of the same tomcat instances. Now we are only using 4 workers to redirect to 4 tomcat servers for 60 multi-user customers. -Matt --- Tore Halset [EMAIL PROTECTED] wrote: Hello! We are using jboss+tomcat on some servers.

which jar files help accomplish JNDI/LDAP/ADS authentication in 4.1.12
I have a configuration of tomcat 4.1.17 which uses a JNDI realm to authenticate to Active Directory Server. It works well. Unfortunately, I must accomplish the same thing in a configuration of Tomcat 4.1.12 in order to be in step with a vendor supplied tool. 4.1.12 is not able to accomplish this particular goal due to a problem in the way it issues an error message inappropriately javax.naming.PartialResultException and then fails to authenticate. I would like to know which jar files I need to copy from my tomcat 4.1.17 to replace in my 4.1.12 in order to accomplish the JNDI/LDAP processing. I've already copied the common/lib/jndi.jar and common/lib/naming-factory.jar and they haven't been enough to fix the problem. I need to move as little as possible so as to maintain the 4.1.12 integrity for my vendor supplied tool. Any suggestions would be so appreciated. Thanks, [EMAIL PROTECTED]

RE: DBCP Performance?
Hi, Hmm, with minIdle set to 20 and assuming your test gets one connection at a time (or less than 20 at a time), I'm a bit confused. One next step would be to really verify that the pool has available connections before the get connection call. You obviously wouldn't do this in a production application, but this is just for debugging a performance test. Cast the DataSource to the concrete implementation type, probably org.apache.commons.dbcp.BasicDataSource, and call getNumIdle on it to verify it's a positive number before calling getConnection. If it's zero or negative your pool is misconfigured and you're creating a new connection, hence the slow performance.

Issue Running Current Forrest Dev under Tomcat 5
Hi, I am coming from the Forrest Mailing List. I noticed that forrest 0.6 was causing a problem when trying to access the Tomcat homepage. I first noticed the problem with Tomcat 5.0.27 (I never tried anything earlier), but it carries through to 5.0.28 and 5.5.1 (I am currently using Windows XP, SunJava 1.5.0 and Tomcat 5.5.1) If I put the WAR file generated by Forrest 0.6 into the webapps dir, Tomcat will unravel the war and I can even access the Forrest site. However if I try to access the Tomcat Homepage (http://mysite.com:8080/index.jsp), the JSP Samples or the Servlet Examples, I get an HTTP:404 error. If I remove the war file and the unraveled webapp and restart Tomcat, I can once again access the Tomcat Homepage. I should say that Forrest 0.5.1 does not cause this behavior with Tomcat. Everything works fine. I have taken several stderr.log snapshots, before the forrest 0.6 installation, with forrest 0.6 installed and with forrest 0.5.1 installed. Right off the bat, starting Tomcat with forrest 0.6 war in webapps causes the stderr.log to grow 130KB rather than 3KB without forrest. The stderr.log is full of various errors: snip Sep 10, 2004 9:49:10 AM org.apache.catalina.core.StandardHost start INFO: XML validation disabled Logging Error: Could not set up Cocoon Logger, will use screen instead org.apache.avalon.framework.configuration.ConfigurationException: cannot create FileTarget snip NFO: Cache file root directory: C:\Programs\ApacheGroup\Tomcat5\work\Catalina\localhost\ForrestExamples\cocoon-files Sep 10, 2004 9:49:23 AM org.apache.tomcat.util.digester.Digester endElement SEVERE: End event threw exception java.lang.reflect.InvocationTargetException at sun.reflect.GeneratedMethodAccessor22.invoke(Unknown Source) snip ep 10, 2004 9:49:23 AM org.apache.catalina.startup.ContextConfig processDefaultWebConfig SEVERE: Parse error in default web.xml org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: java.lang.ClassNotFoundException: org.apache.commons.logging.impl.LogKitLogger (Caused by java.lang.ClassNotFoundException: org.apache.commons.logging.impl.LogKitLogger) (Caused by org.apache.commons.logging.LogConfigurationException: java.lang.ClassNotFoundException: org.apache.commons.logging.impl.LogKitLogger (Caused by java.lang.ClassNotFoundException: org.apache.commons.logging.impl.LogKitLogger)) at org.apache.tomcat.util.digester.Digester.createSAXException(Digester.java:2746) snip and so on..

Hi, I tried your settings, but getNumIdle() still returns 0. Why that?

mod_jk2 : apr_socket_send error
Hi, I am hosted on linux (I'm pretty sure it's redhat, but not 100%), with apache 2.0.40 running to handle my Perl scripts. I want to be able to run Tomcat side-by-side with Apache to handle all JSP requests. I hope that I'm right in figuring out that mod_jk2 is the module that I need... (please correct me if I'm wrong). I installed Tomcat 5.0 just fine. If I do a telnet localhost 8080, and type GET /, I get the You installed Tomcat successfully page. I initially got a binary of mod_jk2.so, and installed it in my Apache modules directory, and added LoadModule jk2_module modules/mod_jk2.so to httpd.conf. I got the following error : Cannot load /etc/httpd/modules/mod_jk2.so into server: /etc/httpd/modules/mod_jk2.so: undefined symbol: apr_socket_send I tried downloading the source and building it instead, but ended up with the same message. I was hoping someone could help me. I've seen a lot of messages in the archive about the apr_socket_send message, but couldn't make sense of them. Thanks. --- Outgoing mail is certified Virus Free.

I noticed that forrest 0.6 was causing a problem when trying to access the Tomcat homepage. I first noticed the problem with Tomcat 5.0.27 (I never tried anything earlier), but it carries through to 5.0.28 and 5.5.1 (I am currently using Windows XP, SunJava 1.5.0 and Tomcat 5.5.1) If I put the WAR file generated by Forrest 0.6 into the webapps dir, Tomcat will unravel the war and I can even access the Forrest site. However if I try to access the Tomcat Homepage (http://mysite.com:8080/index.jsp), the JSP Samples or the Servlet Examples, I get an HTTP:404 error. If I remove the war file and the unraveled webapp and restart Tomcat, I can once again access the Tomcat Homepage. I should say that Forrest 0.5.1 does not cause this behavior with Tomcat. Everything works fine. I have taken several stderr.log snapshots, before the forrest 0.6 installation, with forrest 0.6 installed and with forrest 0.5.1 installed. Right off the bat, starting Tomcat with forrest 0.6 war in webapps causes the stderr.log to grow 130KB rather than 3KB without forrest.

RE: How to create/run a Java Service on UNIX
Hi Daxin, How are you going to genereate the keys? Via the database? Also, seeing as you are going to use 'service' with without Tomcat I'd like to know if either application will be up as long as the server(s) is up. If that's the case you could have both applications check at startup if the daemon is active(running) or not not. If the daemon isn't active either application could start it. If this service should be up whenever the hardware is up you could start the service on boot so it is in theory always available to the 2 applications when they are started but each must check if the daemon is running prior to accessing the daemon. The person who recommended learning daemons was entirely right and without my knowing more of the 2 applications I can not tell you more except since tomcat will access he daemon, I would look closely at the framework in Jakarta to see if it will suit both applications. I haven't looked at it closely and it Tomcat must be running for the daemon to be running(which I doubt) I wouldn't utilize that framework. -Original Message- From: Daxin Zuo [mailto:[EMAIL PROTECTED] Sent: Friday, September 10, 2004 12:03 PM To: Tomcat Users List Subject: RE: How to create/run a Java Service on UNIX First I thank very much for the replies.

RE: How to create/run a Java Service on UNIX
I think we should assume that 'the program' will function correctly and do what it's advertised to do, since if that was the actual problem, then a list like 'java-rmi-user' or 'java-io-user' would be more appropriate. The tomcat application, and that second application should be coded to handle the cases when 'the program' is not available. If that's still a problem, refer to the aformentioned, fictious(?) groups. All that remains is how do I get 'the program' to run? Oddly enough, that's still not tomcat-user, but hey we like to help out. For that (as Yoav said), you need a *nix admin type person to write some rc scripts for you, or investigate how to do so for yourself. Find a BB or other email-user list for the exact flavour of *nix you are running, and ask about rc.d scripts on that list. (rc.d is the approximate equivalent on *nix, of the Windows Services control panel). -Original Message- From: John Najarian [mailto:[EMAIL PROTECTED] Sent: Friday, September 10, 2004 2:28 PM To: 'Tomcat Users List' Subject: RE: How to create/run a Java Service on UNIX Hi Daxin, How are you going to genereate the keys?

Re: How to create/run a Java Service on UNIX
Are you just looking for Unix to start a daemon every time it boots? That's typically done via a shell script, which accepts start stop arguments (sometimes start_msg stop_msg, too). These scripts are in /etc/init.d (/sbin/init.d for HPUX), and there are corresponding links in /etc/rc.* directories. Your flavor of Unix will execute these scripts at boot time (with startup as the arg). You just need to make that script execute your application program or script. Check out the scripts you already have - for example, the lp daemon on my system has the usual shell script and 2 links: find /sbin -name '*lp*' | xargs ls -l # change /sbin to /etc, if not HPUX -r-xr-xr-x 1 bin bin 1604 Oct 27 1997 /sbin/init.d/lp lrwxr-xr-x 1 root sys15 Nov 16 2001 /sbin/rc1.d/K280lp - /sbin/init.d/lp lrwxr-xr-x 1 root sys15 Nov 16 2001 /sbin/rc2.d/S720lp - /sbin/init.d/lp On Fri, 10 Sep 2004 12:02:36 -0700, Daxin Zuo [EMAIL PROTECTED] wrote: First I thank very much for the replies.

RE: How to create/run a Java Service on UNIX
Thank John, Mike, and Tom, and all other repliers. I hope Tome's instruction will work. I left UNIX for a long time. What Tom told is familiar to me. I will test it after next week. It is still a (rare) case that the Sever is not up when one of the applications talks to it. In this rare case, I can try else way. Thanks again. -Original Message- From: Tom Simons [mailto:[EMAIL PROTECTED] Sent: Friday, September 10, 2004 1:31 PM To: Tomcat Users List Subject: Re: How to create/run a Java Service on UNIX Are you just looking for Unix to start a daemon every time it boots? That's typically done via a shell script, which accepts start stop arguments (sometimes start_msg stop_msg, too). These scripts are in /etc/init.d (/sbin/init.d for HPUX), and there are corresponding links in /etc/rc.* directories. Your flavor of Unix will execute these scripts at boot time (with startup as the arg). You just need to make that script execute your application program or script. Check out the scripts you already have - for example, the lp daemon on my system has the usual shell script and 2 links: find /sbin -name '*lp*' | xargs ls -l # change /sbin to /etc, if not HPUX -r-xr-xr-x 1 bin bin 1604 Oct 27 1997 /sbin/init.d/lp lrwxr-xr-x 1 root sys15 Nov 16 2001 /sbin/rc1.d/K280lp - /sbin/init.d/lp lrwxr-xr-x 1 root sys15 Nov 16 2001 /sbin/rc2.d/S720lp - /sbin/init.d/lp On Fri, 10 Sep 2004 12:02:36 -0700, Daxin Zuo [EMAIL PROTECTED] wrote: First I thank very much for the replies.

How to make Apache direct Servlet to Tomcat
My Apache 2.0.49 Tomcat 5.0.19, windows 2000. (Soon I will move them to UNIX) I have a difficult in running servlet from Apache. For example I have a servlet TestServlet.class (package: myServlet) in C:\Program Files\Apache Group\Apache2\tomcat\webapps\ROOT\WEB-INF\classes\myServlet\ I register this servlet in \tomcat\webapps\ROOT\WEB-INF\web.xml: servlet servlet-nameTestServlet/servlet-name servlet-classTestServlet/servlet-class /servlet servlet-mapping servlet-nameTestServlet/servlet-name url-pattern/TestServlet/url-pattern /servlet-mapping Tomcat port is 8008 When I run http://localhost:8008/TestServlet, it runs correctly. Apache port is 82 I cannot start it with http://localhost:82/TestServlet. -- The page cannot be found My Aache and Tomcat is connected correctly. All JSP files can run on both. For example, I have a jsp file C:\Program Files\Apache Group\Apache2\tomcat\webapps\ROOT\testJSP\testDBPool.jsp. I can run http://localhost:82/testJSP/testDBPool.jsp or http://localhost:8008/testJSP/testDBPool.jsp in workers2.properties, I have: [uri:/myServlet/*] group=lb [uri:/WEB-INF/*] group=lb [uri:/WEB-INF/classes/*] group=lb Please forward your instruction.

RE: [OFF-TOPIC]Yoav -- RE: Some pretty basic Tomcat ConnectionPooling Questions????
Hi Yoav and all,
Thanks for your reply,
But you went a bit too far: the DataSource lookup is potentially
expensive. That you can do in the init() method and keep a reference to
the DataSource, because keeping that reference doesn't use a connection
resource.
Then in your servlet methods, get a connection from the DataSource, use
it, and release it.
In your servlet destroy method, null out your DataSource reference.
So the DataSource lookup is done once, the DataSource reference is kept
as a private non-static member variable of the servlet class, and the
Connenctions are used only within methods, they're not class member
variables.
So now I have changed my code to:
1. Declaration of private global variables:
code
private Context ctx = null;
private DataSource ds = null;
private Connection conn;
/code
2. an init() method:
code
// init does DataSource lookup
public void init(ServletConfig config) throws ServletException {
super.init(config);
try {
ctx = new InitialContext();
if(ctx == null) {
throw new Exception(No Context);
}
ds = (DataSource)ctx.lookup(java:comp/env/jdbc/mb);
} // end try block
catch(Exception e) {
e.printStackTrace();
}
} // end init()
/code
3. an openConnection() method:
code
private void openConnection() {
try {
if(ds != null) {
conn = ds.getConnection();
if(conn != null) {
message = Got Connection to DB + conn.toString();
}
}
} // end try block
catch(Exception e) {
e.printStackTrace();
}
} //end method openConnection()
/code
4. a destroy() method that nulls the DataSource:
code
public void destroy() {
ds = null;
}
/code
remarks
-the conn.close() is called in the methods that call openConnection().
-I'm thinking of doing an 'include' for the openConnection method, so I
don't have the code for the same method sitting in multiple classes.
Would that be a good idea? (maintainability, yes but in terms of
overhead?)
/remarks
Would this be the 'leanest' scenario for a database connection?
thanks again,
Luke

Re: at the tomcat start up...log4j error..
At 05:21 PM 9/10/2004 -0400, you wrote: log4j:WARN No appenders could be found for logger (org.apache.commons.digester.D igester). log4j:WARN Please initialize the log4j system properly. Starting service Tomcat-Standalone I am getting the above error as the tomcat starts up, i hav elog4j.jar under commom/lib and log4j.proprties under webapps/myapps/WEB-INF/lib... any clue.. Tomcat itself won't see the log4j.properties in your webapp. There are two issues here: 1. Log4j tries to perform autoconfiguration at Tomcat startup and isn't finding a config file. The solution here is to put a simple log4j.properties or log4j.xml file in common/classes 2. Log4j won't perform automatic configuration for your webapp since the one in common/lib can't see WEB-INF/classes. In this case, there are a few different solutions a. add a copy of log4j.jar to WEB-INF/lib and your config file to WEB-INF/classes and autoconfiguration will happen and only affect your webapp logging. b. perform manual configuration at webapp startup and provide Log4j with the URL of the config file. However, keep in mind that this will configure logging not only for your webapp, but also for any other app that is using Log4j. This is because Log4j is global to all apps. The solution is to do as described in a or do c below... c. use a repository selector so that Log4j can be global, but use a separate logger repository for each application. This is certainly more complex than a, but it is a good option. See more here... http://wiki.apache.org/logging-log4j/AppContainerLogging If you check out the log4j-sandbox code mentioned at that link, make sure to checkout the 0_3_alpha tag, as there are certain files that are required that were removed from the HEAD branch because they were moved into Log4j-1.3 HEAD.
