Customise Tomcat Logger

I want to use my own logging system in Tomcat.
I have looked through a list of forum discussion and still have no idea of how to do that.
Some forum discussion mentioned to use the system properties "java.util.logging.config.class" and "java.util.logging.config.file" to set specify the configuration file.
Is it possible for me to directly overwrite or create a wrapper class to replace the tomcat logging function?

It looks like you are happy with existing tomcat and log4j.Fact is, Tomcat logging is what it is. No matter what tool you choose to throw at it, you're not going to get any more logging out of it unless you trawl through the source code for Tomcat adding your own. But quite what you think you're missing is beyond me, to be honest. All I can think of is, you're unhappy with either the level of detail, or the format of the logging that's coming. And the remedy to that is configuration, not re-inventing an already-good wheel, badly. If you think by writing your own logging framework you're going to magically get extra information out of Tomcat, you're very much mistaken. You still haven't bothered to tell us what you think is missing. Presumably because we mere mortals couldn't possibly comprehend the complex thinkings of someone who, even when it's explained, doesn't understand how logging works
Please do not sell log4j to me any more.I'm not selling anything. Tomcat uses commons-logging, and, by default, log4j. Both of which are free. Feel free to waste your time on a pointless endeavour, rather than read a simple bit of documentation, though

How to view the tomcat errors in another file

hi friends,
i am starting tomcat by using startup.bat, in the console i can see the startupe messages, but when i execute the jsp page it throws some errors, because the window run fast i cannot see the previos errors.
how to redirect these errors in to a file ???
i tried using startup.bat > error.txt, but there it is not writing the errors.In tomcat logs also i cannot see the errrors.
can any one telll how to see this
thanks
vin

Tomcat uses the log4j API. You can put a log4j.properties file in your application classpath (WEB-INF/classes/log4j.properties) and in that properties file you can redirect tomcat log output to a file. The content could be like this:
log4j.properties:
# a default stdout console appender. When debugging from an IDE, this will end up in the output window
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
# tomcat file log appender
log4j.appender.TA=org.apache.log4j.FileAppender
log4j.appender.TA.layout=org.apache.log4j.PatternLayout
log4j.appender.TA.layout.ConversionPattern=%d %p [%c] - %m%n
log4j.appender.TA.File=c:/log/tomcat.log
log4j.appender.TA.append=true
# configure the tomcat logger to use the tomcat file appender. Only warnings and higher are sent to the logfile
log4j.logger.org.apache=WARN, TA
Check out the log4j documentation for more details.

Setting the Logger in Tomcat

Hello Every One!
I am using the Tomcat version 5.5.17
I am new to tomcat, and learning the meaning of the tags in the /conf/server.xml file.
In my version there is no <Logger> tag, but I am reading a book to get the customized logs specific to the application, I run. In this book they have put the <Logger> tag, and so did I.
But I get the following error, when I start Catalina:
INFO: Stopping service Catalina
Dec 16, 2006 9:00:13 PM org.apache.coyote.http11.Http11BaseProtocol destroy
INFO: Stopping Coyote HTTP/1.1 on http-8080

     at org.apache.tomcat.util.digester.Rule.begin(Rule.java:152)
When I remove a <Logger> tag, Catalina runs fine, but the logs specific to the Application does not get generated.
Any sort of help will be highly appreciated.
Regards
Harbir

Thank You Stevejlike!
You are right, the primary objective has been obtained, and it looks as if it is working.
I came here to post the link which you have allready done.
Appreciate your help.

J2SE 1.4 Logger configuration problems with Tomcat 4.0

I'm using Tomcat 4.0 as a servlet container and I'm trying out the new J2SE 1.4 logging API.
Its working fine with the standard settings, which sets the level to INFO on the console handler.
I would like to set the level to FINER to show some debugging info, but can't seem to get it going.
I have tried setting the default level in my %JAVA_HOME%\jre\lib\logging.properties file, but it doesn't want to display log records of level FINER.
I have also change the console handler to FINER by setting java.util.logging.ConsoleHandler.level = FINER
I have also specified the config file parameter to point to a config file explicitly using the -Djava.util.logging.config.file=%CATALINA_HOME%\conf\logging.properties parameter in the catalina.bat script.
Anyone got this working?
--Kim

Solved it. Isn't that always the way, you get frustrated enough to post a message, then you solve it 5 minutes later.
It was a simple problem of the higher level overriding the lower levels.

Problem with JNDI and JSP in Tomcat

Hi,
Basically, what I've done is to use the Tomcat administration web
application to create the DataSource, which looks like it populated the
server.xml (see below). I then try to access the testconn.jsp, and am
getting that "Name java:comp is not bound in this Context" error.
I was wondering if anyone could tell me what I'm doing wrong?
Thanks,

Hi,
First of all, you can find alot of information about this in the forum about jsp's.
I think a good thing to do is not to put your context tag directly into the server.xml file.
What you should do is create a context.xml file with the context-tag in it, and put it in the META-INF directory of your .war file. Upon deployment to tomcat5 this file will be extracted from the war, copied to the conf\enginename\hostname directory, and it will be renamed to contextName.xml.
I think you are developing directly into the webapps directory, and I believe you should avoid that and use the deployment feature of the manager web-app or you should use the deployertool from you ide or standalone ant.
anyway, for starters try to remove the context tag from the server.xml file as described above, and check out the jsp / jdbc forums for simular problems and answers.
good luck

and i studied the the tomcat documentation in that tomcat mentioned
The configuration properties for Tomcat's standard data source resource factory (org.apache.naming.factory.DbcpDataSourceFactory) are as follows:
driverClassName - Fully qualified Java class name of the JDBC driver to be used.
maxActive - The maximum number of active instances that can be allocated from this pool at the same time.
maxIdle - The maximum number of connections that can sit idle in this pool at the same time.
maxWait - The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception.
password - Database password to be passed to our JDBC driver.
url - Connection URL to be passed to our JDBC driver. (For backwards compatibility, the property driverName is also recognized.)
user - Database username to be passed to our JDBC driver.
validationQuery - SQL query that can be used by the pool to validate connections before they are returned to the application. If specified, this query MUST be an SQL SELECT statement that returns at least one row.
how to configure server.xml file
and how to get the org.apache.naming.factory.DbcpDataSourceFactory
please help me...this module is very very urgen to me..

http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.html

Has anyone run the connection pooling for mysql & tomcat successfully?

I'm trying to set up connection pooling. I'm following the how-to page at
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html
But when i test the DBTest/test.jsp file, tomcat displays an error =
could not load jdbc driver class 'null'(msdos)
i have placed all the required .jar files in the tomcat lib.
below is the cofiguration i did to the server.xml file

Pleas4 help!!!

you have your driver jar in Tomcat\common\lib?
if so, check your classpath, it could be that.

Log Messages from Transaction Event Logger

I have 4 instances of MII v12.1 and within a transaction I want to add a message to the log when the transaction runs so I can view it through the message logger. All 4 MII instances were installed by the same consultant a few years ago so there "should" be no differences in the log configs. On 3 of the instances this is working fine - I have created a very simple transaction with one Event Logger action configured with a message "Test Message" and when I execute the transaction I see the correct entry in the log viewer. On the fourth however, although the transaction executes without error I am not seeing anything in the viewer for this event. I am using the standard "last 24 hours" log viewer with no filters and no specific log locations selected, and no customisations. I am seeing other system generated messages. I found some documentation about logging and the viewer and I found the Netweaver log config but as far as I can see it looks consistent between the instance which is working and the one which is not working. Is there some other config which needs to be done to enable Event Logging from transactions? My user has the same access across all instances. Any guidance would be appreciated. I attach a screen shot of what I am expecting to see (taken from one of the instances which is working).

Hi Partha
Many thanks for your reply. I have tried this and unfortunately it makes no difference. I also checked on the other instances and found they have their tracing levels all set to error, not Info. I have also noticed that on the instance which is working, in the System Configuration section at the bottom of the Log Config page - for Applications and all sub categories I see the entry .\log\applications_00.log in the Pattern column. On the instance which is not working I see that entry for the Applications root but not for any of the sub categories (even after selecting Copy to subtree). I cannot see where I can set this value (there is no modify function available, even under Administrator login).
Also, when I look at the log messages which have generated when setting the Event Type to Error on the instance which is not working, it shows one entry and the Category and Location columns show <com.sap.xmii.bls.executables.action.logging.LoggingActions>. When I generate an event with type Error on the instance which is working I get 2 log messages, one with the Category and Location <com.sap.xmii.bls.executables.action.logging.LoggingActions> and the other with Category /Applications/XMII/Xacute/Event and Location <com.sap.xmii.bls.executables.action.logging.LoggingActions>.
I guess that the .\log\applications_00.log should be showing for all subtree items under Applications and because it is not then the messages are not going into any application log. Not sure how to fix this however.
I have also reset to the default configuration and it does not change the above.

Problem in jdbc-tomcat-mysql connection

hi everybody
i m in serious problem since last 15-20 days. i m trying hard to make the connection jdbc-mysql using tomcat with the help of a jsp test page but every time i am facing almost the similar probems listed below in detail:
to make sure that the jdrivers's .jar (mysql-connector-java-3.1.7-bin.jar) available for such connections working fine i have tried the above said connection without using tomcat....which is working fine...for this i have created a dummy database with a dummy table ..and written some queries in the .java file of my code which upon running inserts the specified values in the defined(dummy) database.
this is the confirmation that the classpath etc..are ok in regard to the mysql-connector-java-3.1.7-bin.jar
now i have placed a copy of this .jar file in to the commons/lib directory of the tomcat web server(which is suppossed to be the place for such external jars)
after doing so i have followed 2 methods :
method 1st:........
i have made aone more jar file from the following .java file....
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
public class TestSQLLoad
String user = "Not Connected";
String pwd = "no pwd";
int id = -1;
public void init() {
try{
Context ctx = new InitialContext();
if(ctx == null ) {
throw new Exception("Boom - No Context");
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/TestDB");
if (ds != null) {
Connection conn = ds.getConnection();
if(conn != null) {
user = "Got Connection "+conn.toString();
Statement stmt = conn.createStatement();
String q = "select name, password, id from user";
ResultSet rst = stmt.executeQuery(q);
if(rst.next()) {
user=rst.getString(1);
pwd=rst.getString(2);
id = rst.getInt(3);
conn.close();
}catch(Exception e) {
e.printStackTrace();
public String getUser() {
return user;
public String getPassword() {
return pwd;
public int getID()
return id;
after compiling it at the cmd prompt i made a .jar file from the .class of it and named it MySQLLoad.jar...then i placed it also in to the commons/lib directory where the mysql-connector-java-3.1.7-bin.jar was already placed.
then i have changed the server.xml and web.xml files from the conf directory of the tomcat as given here:

after all this i have taken a jsp page whose code is here:
(the mysql database used is named as "testdb" and the table name is "user" which is having fields name,password and id)
<html>
<head>
<title>DB Test</title>
</head>
<body>
<%
TestSQLLoad tst = new TestSQLLoad ( );
tst.init();
%>
<h2>Results</h2>
User <%= tst.getUser() %>
Pwd <%= tst.getPassword() %>
Id <%= tst.getID() %>
</body>
</html>
and placed it in to the Tomcat 5.5\webapps\tomcat-docs\testdb directory and saved as test-db.jsp
when i run this page on the browser i get a lot may errors stating
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 12 in the jsp file: /testdb/test-db.jsp
Generated servlet error:

javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
note The full stack trace of the root cause is available in the Apache Tomcat/5.5.4 logs.
AND NOW WHEN just to get rid of such errords i try to include a statement
<%@ page import="pkg.TestSQLLoad" %> in the jsp page code (and also place the MySQLLoad.class file in a folder called pkg and place it in the same directory where the jsp page is )and make it look like
<html>
<head>
<%@ page import="pkg.TestSQLLoad" %>
<title>DB Test</title>
</head>
<body>
<%
TestSQLLoad tst = new TestSQLLoad ( );
tst.init();
%>
<h2>Results</h2>
User <%= tst.getUser() %>
Pwd <%= tst.getPassword() %>
Id <%= tst.getID() %>
</body>
</html>
now when i run it i get the following errors:
exception

in response to the above error i have even tried placing the MySQLLoad.class directly in the testdb folder along with the jsp page without keeping it in a package named pkg and then importing directly as <@page import="MySQLLoad" %>
that too gave me the following errors

and if i do not use the statement <%@ page import="MySQLLoad"%> then also i get the errors like

THE 2nd Method:
in my second method i did the same changes in the web.xml and server.xml
then i took a jsp page with the following code:
<%@ page import="javax.sql.*,java.sql.*,javax.naming.*,com.mysql.jdbc.*" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>

DataSource dataSource=(DataSource) context.lookup("java:comp/env/jdbc/testdb");
Connection conn=dataSource.getConnection();
Statement stmt=conn.createStatement();
ResultSet rset=stmt.executeQuery("select * from user");
if (rset.next()){
%>
<table width="100%" border="1">

</tr>
<%
do {
%>

<%
} while (rset.next());
%>
</table>
<%
} else{
%>
No results from query
<%
rset.close();
stmt.close();
conn.close();
context.close();
%>

thanx for ur response
as u said that the problem is more of a jsp page not getting compiled....
me also pointed towards the similar situation providing all the surrounding situations
which i have met and gone through
i m still thinking that problem may b in the tomcat's server.xml and web.xml as well
so better if u plz guide me in that regard
regards,

Jboss/tomcat mapping configuration error

I can't even get the combination to serve a .jsp file or .html file. Regardless of the URL that I attempt, I only get a No Context configured to process this request error from tomcat and INFO [Engine] StandardHost[localhost]: MAPPING configuration error for request URI from JBoss. I've tried to access all of the various webapps under the catalina directory and can't get to any of them. I know that catalina is started because the log file shows

with no errors. I'm confused because I was able to consistently work with previous versions of JBoss with no problem. The configuration seems to have changed radically, is this some recent change that I just can't find a reference to? Thanks for any help.

Hi
For Tomcat 3.x you need to use one of the following options:
(Note: this is with JBoss/Tomcat OR JBoss/Jetty)
Place you .war files in the following location:
C:\jboss-3.0.3\server\default\deploy and the app is automatically available.
If my app's name is DavidOnline.war, when deployed, I can access it at
http://localhost:8080/DavidOnline..
OR
Copy your entire development directory to the deploy direction above, RENAME your
directory from say C:\JspApps to C:\JspApps.war and you can work from that location and see your changes immeadiatly.
There is a file called jboss-service.xml that has some config options, also for the Tomcat bundle there is a file named tomcat-service.xml that has the standard server.xml section.. I suggest you check out the JBoss website, free docs and forums.. http://www.jboss.org.
Thanks, Hope this helps.

How to create Connection pool in Tomcat 5

present i am developing one web site in that i am using tomcat 5.
i am trying to establish connection pooling in tomcat,i am facing some problems..
tomcat throws the following exception ie.,
cannot create JDBC Driver class for connect URL null.
my code lik this
i configured the web.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app>
<resource-ref>

and i studied the the tomcat documentation in that tomcat mentioned
The configuration properties for Tomcat's standard data source resource factory (org.apache.naming.factory.DbcpDataSourceFactory) are as follows:
driverClassName - Fully qualified Java class name of the JDBC driver to be used.
maxActive - The maximum number of active instances that can be allocated from this pool at the same time.
maxIdle - The maximum number of connections that can sit idle in this pool at the same time.
maxWait - The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception.
password - Database password to be passed to our JDBC driver.
url - Connection URL to be passed to our JDBC driver. (For backwards compatibility, the property driverName is also recognized.)
user - Database username to be passed to our JDBC driver.
validationQuery - SQL query that can be used by the pool to validate connections before they are returned to the application. If specified, this query MUST be an SQL SELECT statement that returns at least one row.
how to configure server.xml file
and how to get the org.apache.naming.factory.DbcpDataSourceFactory
please help me...this module is very very urgen to me..

I spent many hours when i first implemented connection pooling trying to put it together. The information is scattered and the config has changed slightly from 5.0 to 5.5 etc. This is how I got it working in 5.5.17:
* server.xml seems to be a wrong place for the pool configuration if you consider it to be an application specific thing. It might be a better idea to put it into C:\tomcat55\conf\Catalina\localhost\ConfigFileForYourWeapp.xml as follows:
<Context path="/ClientLink" docBase="C:\eclipseWorkspace\PortfolioUI3\WebRoot">
      <Resource name="jdbc/testportfolios" auth="Container"
                     type="javax.sql.DataSource"
                     factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory"
                     username="****" password="******"
                     driverClassName="com.mysql.jdbc.Driver"
                     url="jdbc:mysql://192.168.0.101:3306/testportfolios?user=***********&password=***********&useUnicode=true&characterSet=swedish"
                     maxWait="10000" maxActive="30" maxIdle="10" removeAbandoned="true"
                     removeAbandonedTimeout="60" logAbandoned="true" testWhileIdle="true"
                     minEvictableIdleTimeMillis="4000"
                     timeBetweenEvictionRunsMillis="60000" validationQuery="SELECT '1'" />
      </Context>* Then add the following snippet into web.xml in your webapp directory:
<resource-ref>
                <description>Database pool defined in ClientLink.xml</description>
                <res-ref-name>jdbc/testportfolios</res-ref-name>
                <res-type>javax.sql.DataSource</res-type>
                <res-auth>Container</res-auth>
           </resource-ref>* Next put the jdbc-driver jar in a place where tomcat can find it. That is common\lib. Note that the shared/lib does not work.
* Get connections in java as follows:
                try {
                     Context initCtx = new InitialContext();
                     DataSource ds = (DataSource) initCtx.lookup("java:comp/env/jdbc/testportfolios");
                     this.connection = ds.getConnection();
                } catch (NamingException e) {
                     throw new RuntimeException("Java naming exception when getting connection from tomcat pool: " + e.getMessage());
                }I hope that this helps you to save the time I lost figuring this out!
