Limiting processors - WarpConnector
Hi, Iam using Apache 1.3.27, tomcat 4.0.3 , java version 1.4.0 and jakarta-tomcat-connectors-4.0.2-01 in my virtual hosting setup and iam trying to limit the no of java threads spawned by tomcat. The problem is somehow tomcat does'nt use the below settings cos I always see about 99 to 150 threads of java running even though there are no requests to a virtual host. Below is my connector settings.. Connector className = org.apache.catalina.connector.warp.WarpConnector port=20762 minProcessors=10 maxProcessors=25 enableLookups=true appBase=webapps acceptCount=10 debug=0/ What else do I need to do to limit the threads ?.

Re: mod_jk windows 2000 pro
Ok, that will never work with your existing configuration. These lines: VirtualHost localhost ServerName localhost in your mod_jk.conf file tell Apache that requests coming in for localhost get the JkMount directives shown a little farther down. There are no JkMounts for the bostondev URL. You will have to either use the Alias/Alias directive in Tomcat's server.xml to alias the bostondev URL to the already-defined localhost HOST container, or setup another HOST container in server.xml, and change the name parameter to the bostondev URL instead of localhost. Basically, for everything that says localhost in your mod_jk.conf file, you need the same configuration for BostonDev.ad.dstsystems.com...so two VirtualHost containers, total.

Re: mod_jk windows 2000 pro
Also, http://bostondev:8080 works because in the default server.xml, localhost is set as the defaultHost. Even though you have Apache's global ServerName set to the bostondev URL, there are no corresponding JkMount statements, so Apache will never send any requests to Tomcat for bostondev.

We are authenticating internal users for authorization of the Manager webapp. Currently this uses a JDBC Realm. The problem is that the user account for each of our four environments has a different password for security reasons.

Is there someway to configure a realm to call a custom class to get the DB connection? Each webapp is configured as it's own service. Per the docs, we have a manager webapp context for each host.

I've been working on an Intranet site in JSP, and one of the requirements was an
NTLM-login based authorisation. NTLM is a closed Microsoft protocol that sends the
username and domain from Internet Explorer tot a Microsoft webserver. We've been able
to implement this in JSP using information about the protocol found on the Internet.
The NTLM-authentication works fine, however, there is a very strange side-effect:
after the NTLM-login sequence has completed, Tomcat seems to be unable to work with
request-parameters anymore. All request-parameters, for example sent using forms or
encoded in the URL using '?' end up being 'null' when I try to get them using
request.getParameter. Even when I forward to another page and then again another (or
redirect), still, those pages cannot read any request-parameters anymore. Very
strange...
The NTLM-code we use is included below. Maybe any of you can spot an error in it that
causes this effect, or knows more about his mistake/bug?
Tomcat version: latest stable release of Tomcat 4
Operating system: Redhat Linux 6.2
Thanx in advance for any imput you can provide!

Re: Request parameters are all 'null' after using NTLM login-code
NTLM is a bit of a nightmare to create custom code for, I recommend you either
plug Tomcat into IIS and use IIS's authentication and then use
request.getRemoteUser() to get the details or my preferred method is to use
the filter available with JCIFS (http://jcifs.samba.org), just change a few
things in your web.xml file, drop in the .jar file and everything will start
working automagically.

JSP character conversion problem
Hello, We've got a problem with Tomcat 4.1.24. Data is entered and stored in a MySQL database using a JSP/Struts based web application. This process works fine. The input is converted correctly to UTF-8 and to ISO-8859-1 when stored in MySQL. However, when the data is retrieved again (which also works fine) and then stored in the outgoing HTML, something in the character conversion breaks. Some characters which are in the ASCII character range are not displayed correctly (a '?' character is shown instead). We've traced this problem to the JSP - HTML conversion: the data we get back from MySQL is displayed correctly on stdout. Only when the JSP page is compiled and shown in a browser (mozilla, IE) do you see question mark characters in place of unicode characters (some characters which are not displayed correctly are: (z with an accent), (U with a trailing c)) We've tried everything that came up on google searches. Setting the characterEncoding on the servlet request. Setting the Locale of the HttpSession. Putting a page tag in the JSP specifically stating the charset=ISO-8859-1. Even starting Tomcat with the option file.encoding=iso8859-1. None of this works. Does anyone here know what the problem could be?

Resource Reference and server.xml
One of the main reasons of using resource ref's in code is because you get a level of indirection. I see that level of indirection in the J2EE ref impl from Sun, but I don't see that in Tomcat. How can you specify a datasource (let's say) in the web.xml as a res ref different than the one setup in the server.xml. Is this possible? Here's an example: WEB.XML: resource-ref id=mail1 descriptionThis is used to send email/description res-ref-namemail/bay4/res-ref-name res-typejavax.mail.Session/res-type res-authContainer/res-auth res-sharing-scopeShareable/res-sharing-scope /resource-ref SERVER.XML: Resource name=mail/bay4 auth=Container type=javax.mail.Session/ ResourceParams name=mail/bay4 parameter namemail.smtp.host/name valuesmtp.host.net/value /parameter /ResourceParams --- mail/bay4 has to match everywhere, right? Anyway, this all works just fine for me. But I would like to disconnect the reference I use IN CODE, from the resourceparam used in the server.xml. This way I can change the server.xml without affecting the deployed WAR file. You can do this with SUN's Ref impl for the J2EE. Jim Kennedy IT Consultant -
Tomcat JDBC problem
Hi all, I am having a problem making the MySQL JDBC driver version 3 work with Tomcat correctly. I had previously used MySQL JDBC driver version 1 and developed a couple of programs to access my MySQL database. The programs worked just fine with this version of the driver. When I went to upgrade to the newest version of the MySQL JDBC driver I get errors in my programs saying there is an error before the beginning of the result set. I am wondering if I am not installing the driver correctly. All I did for the JDBC driver version 1 was to place the jar file in CATALINA_HOME/common/lib I also made a CLASSPATH variable and referenced the package. Since this worked I thought the it should still work for the JDBC driver version 3. But for some reason it does not. Does anybody have any experience setting up JDBC driver 2 or 3 for MySQL that could give me a few tips on installation.

RE: JSTL and EL question - SOLVED
The setup can be a little simpler than this. The taglib jar can contain
the TLD for the taglib in the META-INF directory of the jar. If it is
present there, you do not have to deploy the TLD separately. In
addition, if the TLD is present there, you do not have to have the
explicit taglib map in your web.xml file. In this case, your taglib
directive in the JSP page needs to specify the URI that is specified in
the TLD in the taglib jar file, which is hopefully documented in the
taglib documentation (so you don't have to open the file in the jar
file).
If this is done correctly, you can skip steps 2 and 3 of this process.

Help with registering a listener
Hello, Could some one please tell me how to register a listener with Tomcat 4? When I add: listener listener-classTnTSearchCleanUp/listener-class /listener within web-app element, tomcat throws 404 errors. Also, I did not find a listener element defined in http://java.sun.com/j2ee/dtds/web-app_2_2.dtd Thank you, Vijay - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: getResourceAsStream cached by Tomcat's Classloader?
I have tried it both ways. My notion is that it has to do with the fact that the getResourceAsStream is being called in a static method and the resulting InputStream, which is wrapped in an InputStreamReader, is passed into an object that is a static variable in my BaseDAO class. So, because the reference is at the Class level it might be holding onto it no matter what I do. If you want I can show you the code. I have some ideas. But, I'm not sure if they will work.

Returning a Resultset...........best practice question
Running: Tomcat 4.1.24, JSDK 1.4.0_03
I'm writing a class to return a resultSet to use in a JSP page or at
least i think thats what i want to do. Whats the best practice to return
that resultset.As the class is written below, when i try to iterate
through the resultset in the jsp page i get a NullPointerException which
i understand because i closed the connection before returningIf i
take out all the code in the finally section i can iterate through the
data no problembut thats not a good idea to leave connections
open...instead of returning a resultset should i return some other
type such as an Array with all the data. How should i return the data?
How can I alter my code for best practice.
==
package foo;
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
public class DBTest{
String foo = Not Connected;
String bar = Not;
public ResultSet getUser(){
Connection conn = null;
Statement stmt = null; //Or preparedStatement if needed
ResultSet rs = null;
try{
Context ctx = new InitialContext();
if(ctx == null)
throw new Exception(Boom - No Context);
DataSource ds = (DataSource)ctx.lookup(java:comp/env/jdbc/Show);
if(ds != null){
conn = ds.getConnection();
if(conn != null){
foo = Got Connection + conn.toString();
stmt = conn.createStatement();
rs = stmt.executeQuery(SELECT * FROM user);
if(rs.next()){
foo=rs.getString(login);
bar=rs.getString(password);
}
}
}
}catch(Exception e){
e.printStackTrace();
}finally{
// Always make sure result sets and statements are closed,
// and the connection is returned to the pool.
if(rs != null){
try{
rs.close();
}catch(SQLException e){;}
rs=null;
}
if(stmt != null){

RE: Help with registering a listener
Howdy, Listeners are a servlet specification 2.3 feature, so you wouldn't find them in the DTD version 2.2. Your XML listener element is correct and sufficient to register a listener in a servlet specification 2.3 container, like tomcat 4.x. The listener class must be available to tomcat: the proper place to put it is the WEB-INF/lib (if it's in a jar) or WEB-INF/classes (if it's not in a jar) of your webapp. Yoav Shapira Millennium ChemInformatics -Original Message- From: Vijay Kandy [mailto:[EMAIL PROTECTED] Sent: Thursday, June 05, 2003 11:32 AM To: 'Tomcat Users List' Subject: Help with registering a listener Hello, Could some one please tell me how to register a listener with Tomcat 4?

Re: JSTL and EL question - SOLVED
Ah, my bad. I thought you were declaring the tab library in the WEB.INF
file kind of like you can declare your database connection:
context-param
param-name
javax.servlet.jsp.jstl.sql.dataSource
/param-name
param-value
jdbc:mysql://localhost:3307/
nfl2003,org.gjt.mm.mysql.Driver,username,password
/param-value
/context-param
I was thinking that you could declare it on the application level and
then not use the %@ taglib % in the JSP pages.
Thanks for clearing that up,

OK, four things when dealing with ANY tag library:
1. PLACE JAR FILES
Place JAR files that hold implementation of the tag library in a
directory where Tomcat will pick it up. Either make it WEB-INF/lib/
(private) or ${CATALINA_HOME}/shared/lib (all web-apps will have
access to it). You could place it in ${CATALINA_HOME}/common/lib,
but I don't see the point in Tomcat having access to those JARs. There
was a discussion recently naming pros/cons of each choice (Craig), so
look up the archives.
2. PLACE TLD
Place TLD files (Tag Library Descriptor) in either WEB-INF/ or (if I
recall correctly) WEB-INF/taglibs/. The first placement will require
for location in web.xml file to be absolute:
/WEB-INF/name.tld, while the second will allow for relative links:
name.tld
3. DECLARE TLD IN WEB.XML
This part you've already seen.
taglib
taglib-urihttp://java.sun.com/jstl/core/taglib-uri
taglib-location/WEB-INF/c.tld/taglib-location
/taglib
4. DECLARE TLD USAGE IN JSP
This you've seen
%@ taglib uri=http://java.sun.com/jstl/core; prefix=c %
The prefix is up to you.

Re: commons-logging not working [was log4j not working]
You are using commons-logging and not log4j directly. Please don't state
that log4j isn't working when you aren't using it directly. I don't have
the slightest clue of how to get your commons-logging config working, but
one fix is to dump commons-logging and use log4j directly. You will have
far fewer problems. See http://www.qos.ch/logging/thinkAgain.html .

see:

Tomcat Manager deploy and undeploy
I finally had my Catalina-Ant undeploy task working after I included context.xml into my war's META-INF directory. What this deployment doing is - war is uploaded to $CATALINA/work/Standalone/my.host/manager; - war is unpacked into $CATALIAN_HOME/webapps/myapp; - context.xml is extracted to manager directory as myapp.xml; - server.xml is modified to include the content in myapp.xml; - myapp is loaded. I noticed that myapp's docBase in the modified server.xml is the war in manager directory. This helps to undeploy myapp but prevents me from reading my configuration xmls from WEB-INF/conf. I cannot getServletContext().getRealPath(/) to get $CATALINA_HOME/webapps/myapp. According to Servlet API doc, getRealPath returns null if content is available from war. I don't want to hard-code the path into web.xml as init-param or into my init Servlet. Does any one have input?

RE: getResourceAsStream cached by Tomcat's Classloader?
Are you using this code to get a classloader? Thread.currentThread().getContextClassLoader(); If not, you are not getting tomcat's you are getting the system one. Are you sure this is true? A ClassLoader can have a parent ClassLoader. But, a class does not maintain a single copy across all ClassLoader contexts. Therefore, the Class type can exist in multiple ClassLoaders. So a Class has a reference to it's ClassLoader context when it is created. When the this.getClass().getClassLoader() is called it calls the context that the class was loaded in. I think you would have to specifically call the getParent() of the Classloader in order to go up the Classloader chain. In this situation I think Thread.currentThread().getContextClassLoader() and this.getClass().getClassLoader() will accomplish the same thing.

stdout log file for Tomcat Windows Service
I am running Tomcat 4.1.24 as Windows Service in production environment. I have a server_stdout.log file for logging the stdout. However, I have two problems with this log file: (1) I added -verbose:gc option as the JVM option when install the Windows service, however, no GC info is logged in this file. How can I make GC info to be logged in this file? (2) Every time when I restart the service, this file will be overwritten. Is there a way to prevent this? Thank you for your help!

package basicServlets does not match directory error message... help !
It seems I have corrected the previous error but now have an error message that says: BasicServlet.java: Error #: 302 : cannot access class javax.servlet.GenericServlet; java.io.IOException: class not found: class javax.servlet.GenericServlet at line 4, column 22 Thanks Joseph Hi I'm a Java student starting to learn about Tomcat and Servlets, and i am trying to run the Servlets using JBuilder 8 Personal. I loaded a basicServlets package that contains one class called BasicServlet. When I tried to compile the class the error message said: BasicServlet.java: Error #: 901 : package basicServlets stated in source C:\Documents and Settings\Gateway User\jbproject\basicServlets\src\basicservlets\BasicServlet.java does not match directory basicServlets at line 1, column 9 Your advice is appreciated Joseph
RE: problem with updating an web app through manager app (linux w ork, win no)
I assume that you put your webapp's context in server.xml, something like Context path=/myapp docBase=myapp debug=5 reloadable=true crossContext=false Logger className=org.apache.catalina.logger.FileLogger prefix=myapp_log. suffix=.txt timestamp=true/ Resource name=mail/Session auth=Container type=javax.mail.Session/ ResourceParams name=mail/Session parameter namemail.smtp.host/name valueexchange.myhost.com/value /parameter /ResourceParams /Context Before I use Tomcat Manager to deploy myapp, I stored this context in an XML file called myapp.xml, drop it off $CATALINA_HOME/webapps and copy my app files to $CATALINA_HOME/webapps/myapp. With Tomcat Manager, I have to use context.xml to let the manager extract it from myapp.war. -Original Message- From: Emerson Cargnin [mailto:[EMAIL PROTECTED] Sent: June 5, 2003 1:43 PM To: Tomcat Users List Subject: Re: problem with updating an web app through manager app (linux w ork, win no) what would be this context.xml?

Sharing a connection pool among contexts
Hi, I have configured the commons-dbcp datasource as a JNDI resource for MSSQL and Oracle and all is working as expected. However, as I understand, it is only possible to keep a factory as a resource and so a new datapool must be created everytime a JNDI lookup is done. I would like to share a single connection pool among different contexts. My first attempt was to create a listener that put a single instance of a pool into the JNDI only to find that it is read-only. For my next attempt I am thinking of creating a javabean with a static collection of datasources and name keys that can be gotten as a JNDI resource so that the different applications can just retrieve the bean and do a lookup of the datasource that way. Am I missing an easier or better way to do this? I do not have any experience with Javabeans and based on the stuff I've seen on the web beans are usually graphic oriented. Is this an appropriate use of a bean (or perhaps an Enterprise Javabean)? Thank you in advance, Scott - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

logic:forward tag and tile definitions...
Hi, In a struts logic:forward tag can the forward referenced by the name attribute be a global forward where the path is a tile definition? This does not seem to be the case, but I want to verify. I can forward to the same page defined by the tile definition using an ActionForward in an Action class, but I cannot forward to the page using the logic:forward tag. In a JSP: logic:forward name=myTileDefinitionPage/ In the struts-config: global-forwards forward name=myTileDefinitionPage path=myTileDefinition/ /global-forwards where myTileDefinition is a tile definition in my tile-definitions.xml file.

I'm not being sarcastic. I am just trying to think of an instance where it makes sense. Two cases come to mind: - Running from a non filesystem-based server that can't unpack wars. Oracle's servlet container was like this (at least used to be), as it used the DB instead of the filesystem to serve resources. - When you want to just have one file (the .war) for your app, and you want to prohibit (for intellectual property legal protection etc.) users from examining its contents. Note that the servlet specification does not mandate filesystem support for web applications. That said, it's always a debate on whether WAR should be seen as a packaging format only, to be unpacked on the server, or an equivalent to an executable file on windows, which is one unit.

So I have a servlet, with all configuration of the pools in param in the web.xml. this servlet can create pools (in its init method), test and show it, and show statistics. I works great, and I can share a pool among contexts. I use the bitmechanic connection pool, a little old, but still works. http://www.bitmechanic.com/projects/jdbcpool/dist/jdbcpool-1.0b1.zip I put the jar of the pool in the common/lib dir. I f anyone is interested in the ConnectionManager, I can share it, it's an eclipse project with ant build file that generates both war and the lib jar. Hope it can help :) Emerson Scott wrote: Hi, I have configured the commons-dbcp datasource as a JNDI resource for MSSQL and Oracle and all is working as expected. However, as I understand, it is only possible to keep a factory as a resource and so a new datapool must be created everytime a JNDI lookup is done. I would like to share a single connection pool among different contexts. My first attempt was to create a listener that put a single instance of a pool into the JNDI only to find that it is read-only. For my next attempt I am thinking of creating a javabean with a static collection of datasources and name keys that can be gotten as a JNDI resource so that the different applications can just retrieve the bean and do a lookup of the datasource that way. Am I missing an easier or better way to do this? I do not have any experience with Javabeans and based on the stuff I've seen on the web beans are usually graphic oriented. Is this an appropriate use of a bean (or perhaps an Enterprise Javabean)?

But, a class does not maintain a single copy across all ClassLoader contexts. Therefore, the Class type can exist in multiple ClassLoaders. So a Class has a reference to it's ClassLoader context when it is created. When the this.getClass().getClassLoader() is called it calls the context that the class was loaded in. I think you would have to specifically call the getParent() of the Classloader in order to go up the Classloader chain.

RE: [SOLVED]RE: getResourceAsStream cached by Tomcat's Classloader?
I checked out tomcat from the HEAD and found the following information in
the WebAppClassloader:
I see now that the WebAppClassLoader does intend to have a cache for the
loaded Resources (some day).
code snip
WebappClassLoader - Line 1211
...
// (0) Check for a cached copy of this resource
stream = findLoadedResource(name);
...
code snip
It does this by examining the ResourcEntry(s) in the resourceEntries Hashmap
and checking binaryContent (null vs not null).
code snip
WebappClassLoader - Line 1898
...
/**
* Finds the resource with the given name if it has previously been
* loaded and cached by this class loader, and return an input stream
* to the resource data. If this resource has not been cached, return
* codenull/code.
*
* @param name Name of the resource to return
*/
protected InputStream findLoadedResource(String name) {
ResourceEntry entry = (ResourceEntry) resourceEntries.get(name);
if (entry != null) {
if (entry.binaryContent != null)
return new ByteArrayInputStream(entry.binaryContent);
}
return (null);
}
}
...
code snip
But, there is no caching going on when the resources are loaded. So, the
code is executing with no purpose? Matter of fact the code has //FIX ME
cache??? statements intermingled with the ClassLoader delegation.
code snip
WebappClassLoader - Line 1219
...
// (1) Delegate to parent if requested
if (delegate) {
if (debug = 3)
log( Delegating to parent classloader);
ClassLoader loader = parent;
if (loader == null)
loader = system;
stream = loader.getResourceAsStream(name);
if (stream != null) {
// FIXME - cache???
if (debug = 2)
log( -- Returning stream from parent);
return (stream);
}
}
// (2) Search local repositories
if (debug = 3)
log( Searching local repositories);
URL url = findResource(name);
if (url != null) {
// FIXME - cache???
if (debug = 2)
log( -- Returning stream from local);
stream = findLoadedResource(name);
try {
if (hasExternalRepositories (stream == null))
stream = url.openStream();
} catch (IOException e) {
; // Ignore
}
if (stream != null)
return (stream);
}
// (3) Delegate to parent unconditionally
if (!delegate) {
if (debug = 3)
log( Delegating to parent classloader);
ClassLoader loader = parent;
if (loader == null)
loader = system;
stream = loader.getResourceAsStream(name);
if (stream != null) {
// FIXME - cache???
if (debug = 2)
log( -- Returning stream from parent);
return (stream);
}
}
// (4) Resource was not found
if (debug = 2)
log( -- Resource not found, returning null);
return (null);
...
code snip ---
So there are three things that I can conclude as a result of seeing this
code.
1) My getResourceAsStream loading problems are NOT caused by Tomcat because
Tomcat is grabbing the resource fresh each time.
2) Resource caching still needs to be implemented in Tomcat
3) The caching check in Tomcat does not check resource Timestamps. So, even
if the cache was working it would not reload resources upon file changes.
(only binaryContent is being checked. eg null or not null).
Are my observations correct?

Classloader?
Howdy,
Dang it! I knew it was too good to be true. Well, it works just fine
for
me.
I do not deal with WARs. Anywyas, why would anyone want to run from a
packed WAR anyways (instead of unpacked)? I'm not being sarcastic. I
am
just trying to think of an instance where it makes sense.
Two cases come to mind:
- Running from a non filesystem-based server that can't unpack wars.
Oracle's servlet container was like this (at least used to be), as it
used the DB instead of the filesystem to serve resources.
- When you want to just have one file (the .war) for your app, and you
want to prohibit (for intellectual property legal protection etc.) users
from examining its contents.
Note that the servlet specification does not mandate filesystem support
for web applications.
That said, it's always a debate on whether WAR should be seen as a
packaging format only, to be unpacked on the server, or an equivalent to
an executable file on windows, which is one unit.

Comment these two filters out of the examples web.xml if you want to see the rest of the examples. If you need a stable environment, I suggest you try tomcat 4.1.24.

MS Access = bad bridge driver = bad If you must use MS Access, you will need a bridge driver. The best you can do is a Type 3 driver, like the one at easysoft.com. If that isn't an option, the Type 1 bridge driver is part of the Java 2 SDK: package sun.jdbc.odbc. Check the SDK docs.

Re: [OFF-TOPIC] Re: JDBC and MS Access DB connectivity.
Hi John, From the functional specs on http://industry.java.sun.com/products/jdbc/drivers, EasySoft's driver does not support DataSources! From Tomcat 4 documentation, it appears as you need to have a jar file (physical copy) of the driver placed in common/lib directory in order for Tomcat to set its classpath. Is this the case for built in generic drivers also, such as sun.jdbc.odbc. I'm getting the error ' Driver not found in the classpath.' when I try DataSource mechanism.

However, as I understand, it is only possible to keep a factory as a resource and so a new datapool must be created everytime a JNDI lookup is done. I would like to share a single connection pool among different contexts. My first attempt was to create a listener that put a single instance of a pool into the JNDI only to find that it is read-only. For my next attempt I am thinking of creating a javabean with a static collection of datasources and name keys that can be gotten as a JNDI resource so that the different applications can just retrieve the bean and do a lookup of the datasource that way. Am I missing an easier or better way to do this? I do not have any experience with Javabeans and based on the stuff I've seen on the web beans are usually graphic oriented. Is this an appropriate use of a bean (or perhaps an Enterprise Javabean)?

Sun JVM vs. JRockit
Info for those interested in benchmarking Tomcat + JVM. Original configuration: Windows 2000. 256 MB Ram JVM: 1.3.1 Tomcat 4.0.4 with Jasper2 Application is struts based (1.0.2) This server was upgraded to Tomcat 4.1.24 and JDK 1.4.1 After having set up everything, I realized that the performance had drop considerably. For example, a request to the same page (20 threads) before the upgrade was producing 6.5 pages/sec. After the upgrade to Tomcat 4.1.24 and JDK 1.4.1 the performance was 4.3 pages/sec. Since I was't sure what was producing this performance degradation, I started to experiment with JDBC, Connectors, etc, but no change. Only when I degraded the JVM to 1.3.1, the performance went up to 8 pages/sec. Since our next release of the application uses features from JDK 1.4.1, I could not stay in JDK 1.3.1. So I decided to try BEA's JRockit 8.1 which complies with Sun's JDK 1.4.1. The performance improved greatly to 14 pages/sec. The problem now was that I could not run Tomcat as an NT service using JRockit. The service would start, but after a few seconds, it would die abruptly. No errors reported. I saw one posting in this list with the same problem, but no solution. So I decided to install the Java Service Wrapper (http://wrapper.tanukisoftware.org/) After setting it up, I was able to run Tomcat with JRockit as an NT service. So far it looks really promising. We will conduct some more testing during the rest of the week and hopefully install this configuration in our production servers next week.

mod_jk2 and shm
I keep getting errors like the following from my mod_jk2 installation. Everything seems to work fine but my apache_error log has errors relating to the shm worker which I don't even configure in workers.properties since I don't see that it's in any way required for a simple channel.socket configuration. My load balancing through Apache seems to work fine too so I'm pretty confused. I've inlined the errors followed by OS and Apache information followed by my workers2.properties. I'm using Tomcat 4.1.24. Should I be configuring Apache to use an on-disk scoreboard file and should I be configuring the shm worker to point to that file?

RE: JSTL and EL question - SOLVED
The jar file is not encrypted, it's just a zip file. Look in the
META-INF directory for a .tld file. This file will also tell you
what URI you need to use in the uri attribute of the taglib
directive in your JSP page.

The setup can be a little simpler than this. The taglib jar can
contain
the TLD for the taglib in the META-INF directory of the jar. If it
is
present there, you do not have to deploy the TLD separately. In
addition, if the TLD is present there, you do not have to have the
explicit taglib map in your web.xml file. In this case, your
taglib
directive in the JSP page needs to specify the URI that is specified
in
the TLD in the taglib jar file, which is hopefully documented in the
taglib documentation (so you don't have to open the file in the jar
file).
If this is done correctly, you can skip steps 2 and 3 of this process.

I thought I liked the idea of having the taglib in the web.xml
file.
When I try it I'm getting This absolute uri
(http://java.sun.com/jstl/core) cannot be resolved in either
web.xml
or
the jar files deployed with this application. Do I have to
download
it
somewhere in order to use it in the web.xml file? Any ideas?
:-)
OK, four things when dealing with ANY tag library:
1. PLACE JAR FILES
Place JAR files that hold implementation of the tag library in a
directory
where Tomcat will pick it up. Either make it WEB-INF/lib/
(private)
or
${CATALINA_HOME}/shared/lib (all web-apps will have access to it).
You
could place it in ${CATALINA_HOME}/common/lib, but I don't see the
point
in Tomcat having access to those JARs. There was a discussion
recently
naming pros/cons of each choice (Craig), so look up the archives.
2. PLACE TLD
Place TLD files (Tag Library Descriptor) in either WEB-INF/ or (if
I
recall correctly) WEB-INF/taglibs/. The first placement will
require
for
location in web.xml file to be absolute: /WEB-INF/name.tld,
while
the second will allow for relative links: name.tld
3. DECLARE TLD IN WEB.XML
This part you've already seen.
taglib
taglib-urihttp://java.sun.com/jstl/core/taglib-uri
taglib-location/WEB-INF/c.tld/taglib-location
/taglib
4. DECLARE TLD USAGE IN JSP
This you've seen
%@ taglib uri=http://java.sun.com/jstl/core; prefix=c %
The prefix is up to you.
Nix.
