Tomcat Performance Concerns
I have a simple JSP-application that makes use of an ODBC database (access). When I run it using Tomcat on PC2 (XP) its performance is very good. However, running on PC1 (W2K Server) is orders of magnitudes slower! :-( I have already read most of the relevant manuals and tried various settings (server.xml, JAVA_OPTS, ...). No help.

Reloading JAAS Configuration File
Hi all, I was wondering if there is a smarter way to reload a jaas configuration file than to call Configuration.getConfiguration().refresh(); in a servlet. I was thinking of such a call in a webapp lifcycle listener. I really don't know much about JMX but perhaps it should the only nice way? Idea ?

Re: problems with connector
Hi Enrico, it looks like the config you sent doesn't fit to your problem. The only configured forwarding rule with JkMount is a comment, so mod_jk should never try to reach any tomcat. I assume, you added the comment sign when trying to find the reason to your problem, but this makes me question the rest of the config, e.g. the connection_pool_size comment. Before we try to solve your problem: the following lines in your workers.properties are obsolete, or not used in your situation. You should remove them: workers.tomcat_home=/tomcat/dir workers.java_home=/opt/jdk ps=/ worker.ajp12.port=8007 worker.ajp12.host=localhost worker.ajp12.type=ajp12 worker.ajp12.lbfactor=1 #worker.ajp13.connection_pool_size worker.loadbalancer.type=lb worker.loadbalancer.balance_workers=ajp12, ajp13 worker.inprocess.type=jni Now to your problem: Please add worker.ajp13.socket_timeout=0 to your workers.properties and try again. If you can easily reproduce the problem, it would be nice to increase JkLogLevel to trace (will produce lots of logging) and attach the JkLogFile.

Re: Tomcat Performance Concerns
Can you determine which part of the system is running slowly? One thing to try would be a simplified version of your application that doesn't access the database - if it is still slow then you know it's not related to the DB. You could also add logging messages at various points to measure how long different parts of the application take. That will tell you what operation is taking all the time. (I can't think of any particular reason why Win 2000 would be so much slower than Win XP.) Also, make sure you're allocating a good amount of memory for the JVM on the slow machine, so it doesn't spend all its time in garbage collection. As for the Access database, I've used Access on a development machine with no problems. (I used the Access ODBC driver and Sun's JDBC-ODBC bridge.) Performance definitely wasn't as good as MySQL or SQL Server, but it was fine for development and testing. -- Len On 11/18/06, Gaurav Kushwaha [EMAIL PROTECTED] wrote: I have a simple JSP-application that makes use of an ODBC database (access).

However, the Microsoft JDBC drivers for that are not well regarded, and should be replaced by more robust open-source versions (Google or search the Tomcat archives for recommendations): http://marc.theaimsgroup.com/?l=tomcat-userr=1w=2 I would look at breaking single-tier to three tier architecture to decouple the application, business and DB to differing structures Don't assume that a multi-tier implementation requires multiple boxes. It's perfectly fine to run multiple layers on a single system as long as you don't require the ultimate in performance and isolation (and few applications really do). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Pooling Issue
I'm having problems setting up connection pooling with comcat 5.5.2.0 and MySQL 5.0.24 using mysql connector/J 5.0. I've setup / populated a test database and verified that I can login to the server/db using the specified username/password/host found in the connection string. My server.xml looks like this: !-- Example Server Configuration File -- !-- Note that component elements are nested corresponding to their parent-child relationships with each other -- !-- A Server is a singleton element that represents the entire JVM, which may contain one or more Service instances. The Server listens for a shutdown command on the indicated port.

SSL support requires the following steps (see the SSL Config HOWTO in the Tomcat 5 documentation bundle for more detailed instructions): * If your JDK version 1.3 or prior, download and install JSSE 1.0.2 or later, and put the JAR files into $JAVA_HOME/jre/lib/ext. * Execute: %JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA (Windows) $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA (Unix) with a password value of changeit for both the certificate and the keystore itself. By default, DNS lookups are enabled when a web application calls request.getRemoteHost(). This can have an adverse impact on performance, so you can disable it by setting the enableLookups attribute to false. When DNS lookups are disabled, request.getRemoteHost() will return the String version of the IP address of the remote client. -- !-- Define a non-SSL HTTP/1.1 Connector on port 8080 -- Connector port=8080 maxHttpHeaderSize=8192 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false redirectPort=8443 acceptCount=100 connectionTimeout=2 disableUploadTimeout=true / !-- Note : To disable connection timeouts, set connectionTimeout value to 0 -- !-- Note : To use gzip compression you could set the following properties : compression=on compressionMinSize=2048 noCompressionUserAgents=gozilla, traviata compressableMimeType=text/html,text/xml -- !-- Define a SSL HTTP/1.1 Connector on port 8443 -- !-- Connector port=8443 maxHttpHeaderSize=8192 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false disableUploadTimeout=true acceptCount=100 scheme=https secure=true clientAuth=false sslProtocol=TLS / -- !-- Define an AJP 1.3 Connector on port 8009 -- Connector port=8009 enableLookups=false redirectPort=8443 protocol=AJP/1.3 / !--
Re: Pooling Issue
For starters, you might want to make a copy of your server.xml file for documentation purposes and then drop all the comments from the active one. The documentation comments are excellent, but they make the serverl.xml near impossible to read. At any rate the exception is connection refused. Are you sure your MySQL server is listening on port 3306? Some default configurations use unix sockets exclusively -- something java JDBC drivers can't do. Try this from the same machine your server is on: mysql -h localhost -P 3306 -u rpd -p The above command forces mysql client to connect via TCP/IP with userid rpd and prompt for a password. If this works, then we're looking at something else. If this doesn't, reconfigure your mysql server to listen on tcp/ip port 3306 and try again. Some additional recommendations -- not directly related to your issue, but worth mentioning: The Context ... ... /Context block should be in it's own xml file under conf/Catalina/localhost, named to match the context of your webapp -- DBTest.xml in your case. Avoid setting this in server.xml as it requires restarting the tomcat container every time you want to make a change to your webapp's config. Drop the autoReconnect=true from your database url. It isn't recommended by MySQL and doesn't make sense in a database connection pool anyway. --David tyju tiui wrote: I'm having problems setting up connection pooling with comcat 5.5.2.0 and MySQL 5.0.24 using mysql connector/J 5.0.

Re: Response encoding problem
Hi - I'm trying to show utf-8 data in the browser from my jsp page.
When the page renders, its character encoding is iso-8859-1, according
to the browser. The http
response headers have the same encoding (iso-8859-1).
Here's what's been done thus far:
1) meta tag set as follows:
meta http-equiv=Content-Type content=text/html; charset=utf-8/
2) jsp page encoding directive issued at the start of the jsp page.
[EMAIL PROTECTED] contentType=text/html; charset=UTF-8%
3) Generated jsp page has the following java code, as a consequence:
try {
_jspxFactory = JspFactory.getDefaultFactory();
response.setContentType(text/html; charset=UTF-8);
pageContext = _jspxFactory.getPageContext(this, request, response,
null, false, 8192, true);
application = pageContext.getServletContext();
config = pageContext.getServletConfig();
out = pageContext.getOut();
_jspx_out = out;
...
4) When I save the page as an html file and open it as an html file in
the browser, it renders correctly (due to the meta tag and no http
headers), which is expected.
5) Manually changing the page encoding in firefox results in the page
being rendered correctly.
6) Also set utf-8 in the connector settings in tomcat/conf/server.xml
(for GETs?)
Connector className=org.apache.coyote.tomcat4.CoyoteConnector
port=8080 minProcessors=5 maxProcessors=75
URIEncoding=UTF-8 useBodyEncodingForURI=true
enableLookups=true redirectPort=8443
acceptCount=100 debug=0 connectionTimeout=2
useURIValidationHack=false disableUploadTimeout=true /
7) Set utf-8 in web.xml as follows:
servlet
servlet-namejsp/servlet-name
servlet-classorg.apache.jasper.servlet.JspServlet/servlet-class
init-param
param-namejavaEncoding/param-name
param-valueUTF8/param-value
/init-param
...
However, the page still shows up as iso-8859-1 (in firefox and IE),
and viewing the response headers using a 3rd party plugin shows the
content-type as ISO-8859-1
Tomcat: 4.1.31
JDK: 1.4.2
What I'm hoping to learn is how to set the http response headers
correctly. It seems that the generated java code is doing the right
thing. However, the response header is still jacked...
Any help will be very, very much appreciated! I've gone through
several articles on Goog as well as the tomcat mailing list... The
brick wall is getting bloodier, and I'm getting woozy from the
pounding...

Re: Response encoding problem
I don't know if this helps, but I had a similar problems once, and it
was caused by a filter which was reading a parameter from the request.
This first access set the encoding to 8859-1, overriding all my
following settings.
I would start from this ... hope this helps.
Good luck!

Re: Response encoding problem
If your JSP page is being included from another servlet, then it won't be
allowed to set the content-type (or charset) of the response. Just a wild
guess here :).
The HTTP/1.1 RFC states that the character encoding of the headers is
iso-8859-1. That is why Tomcat doesn't provide an option to change it.

Re: Response encoding problem
Thanks for all your help. Here's some more data and an update:
1) The jsp is basically displaying unicode strings from the db. So,
there is no other data other than a directive to print the string from
the db.
2) Running a direct query from the db shows the string correctly. The
db is mysql. The table type is innodb. The charset has been set to
utf-8.
3) Currently, the locale is set as follows:
% java.util.Locale locale = request.getLocale();
String userLocale = locale.toString(); %
fmt:setLocale value = ${userLocale}/
When I changed that to force the locale to utf-8, the browser
(firefox) was showing the page encoding as utf-8. The response
headers were utf-8. However, the string now was getting 'double
encoded', and was still showing up jacked.
I will try the filters route, and will try and see what is getting
passed in and out.
Will also try working with a very basic jsp page that just prints out
a static string to see how things are flowing through the app.
Any links on the 'best practices' to follow for such a scenario
(showing utf-8 strings from the db)?
Thanks in advance!

Re: Pooling Issue
I do have a firewall, but I tried opening port 3306 and still had the same problem. I don't know what could be impeding the connection since I'm able to connect to mysql from the server. Is there any other way for me to test the connection using from tomcat? Maybe an interactive logon or something?

Re: problems with connector
Hi; just to give my 2-cents as a mod_jk user, i had a similar problem where mod_jk and tomcat was working ok, and apache was also working ok, but sending blank pages to the user. noticed the mod_jk log had grown to over 3GB in size, then deleted and restarted services and started working fine. later implemented a method to rotate mod_jk log at 200MB.
