Subject: Session affinity doesn't work
Hi all,
I have downloaded these following packages and installed them on my
machine (Win 2K):
Apache 2.0.47
Tomcat 2.0.47
Jk2_mod connector 2.0.43.
I have 2 instances of tomcat (tomcat1, tomcat2 on the same host) on my
machine on a load balancing environment. The load balancing works well
with one exception: the session affinity doesn't work as expected.
Everytime I refresh my browser, it gives me a different session id. If
anyone experimented this problem, please help me.
These are my settings and modifications to apache and tomcat.

At the ROOT directory of each tomcat instance, I create a jsp file with
a single command "request.getSession().getId()"
Then I start tomcat1, tomcat2, apache (in order). Everything is OK. No
error reported on the screen.
The only bad thing is that with every request, this page returns a
different session id (they are suffixed with .tomcat1 and .tomcat2), if
the session affinity works correctly, they must be the same, right? Is
there anything wrong with my configuration?
If anyone have solution, please share it to me. I appreciate it.

Re: Tomcat doesn't start under Windows XP
I see in another post that you've got tomcat to startup. :) The reason your approach here didn't work is because you set the JAVA_HOME variable locally in the current shell. When you then executed startup.bat it started another shell in which to run tomcat. This new shell didn't have its parent's environment variables, only the ones set globally. Setting the environment variables using Control Panel was definately the way to go. Setting the environment variables globally allowed tomcat to start. Changing JAVA_HOME to being an SDK install rather than a JRE will allow tomcat to compile jsp files on the fly. Enjoy, Jon Giorgio Franceschetti wrote: Hardee, Brenda G NAVSAFECEN wrote: I had the same problem installing Tomcat under Win2000. Be sure that all your environment variables are set properly.

Turning cookie JSESSIONID off (selectively)
Hi. Is it possible to turn JSESSIONID cookie off, but just for several pages? I have problem with caching tomcat-generated html pages (tomcat 4.1.x) using Squid in reverse-proxy mode and I suspect it is because of this cookie. I cannot turn it at all, because my webapp has parts requiring session information. Any suggestions will be appreciated.

Sure they can. If you're not loading your Contexts via special classloaders,
then it's as simple as getting an instance of your application's objects and
making use of them.
See an example that I've mentioned below.
If you're using custom classloaders to load Contexts in separate classloaders,
you need to give information
on the Classloader hierarchies that you're using.

a. Get hold of your application's objects via JNDI.
b. Create a class called the Environment, and register your application objects
into this class.
Such a class could be just a wrapper for a Hashtable. Make this Environment
class a Singleton.
Next, from within the contexts, access this Environment singleton, and go on to
access your application objects.
e.g. To share a data source between a Context and your application, you might
try:
// in your application
Environment env = Environment.getInstance();
Connection connection = createConnection(); // returns a connection to a
database.
env.registerObject("DataConnection",connection);
// In your web application
Environment env = Environment.getInstance();
Object anObject = env.getObject("DataConnection");
if(anObject==null)
throw new Exception("No Data Connection in environment !");
Connection connection = (Connection) anObject;
connection.execute("select * from sales");

Using JMX to talk to TC5
All: I had once developed a GUI that used the Tomcat code TC 4.0.1 to deliver a Swing UI that is functionally similar to IBM's Websphere GUI Console in a limited sort of way. I'd referred to Embedded's main(), to learn how to create Contexts, Connectors, etc, and create these as required within my Swing application (MVC style design). I'm now working on porting the code to make use of TC5. Could someone please advice me on: 1. What is the paradigm in TC5/JMX ? Do I need to register with some central object that notifies me about TC5 events such as Context creation, failures, etc? 2. Could I connect to the TC5 objects via JMX and make changes to them ? I know I should read the source, but I will have access to high speed internet only tomorrow, and would like to be better armed on exactly what I need to download and read.

Re: Unable to find servlet class after reload
Hi: Just a blind shot (I've not used Struts yet). Do these load-on-startup servlets require anything to be initialized in struts ? Does Struts require initialization by the web app developer ? If so, perhaps you need to somehow ensure that such initialization takes place before you load your servlets ? Separately, what exactly do you mean by "reloads cause the errors" ? Does everything work fine when Tomcat is started ? If this is the case, then perhaps you need to try maintaining webapp specific copies of files that you're using from common/lib - stuff like struts, for e.g. Perhaps this is a problem with Classloader hierarchies. -- Sriram --- Christopher Schultz <[EMAIL PROTECTED]> wrote: > All, > I'm not sure exactly when this started happening, but now reloads cause > all my load-on-startup servlets classes to cause the following errors: > > 2003-10-25 11:57:14 StandardContext[/diagnosis]: Servlet /diagnosis > threw load() exception > javax.servlet.ServletException: Wrapper cannot find servlet class > org.apache.struts.action.ActionServlet or a class it depends on > at > org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:891) > . > . > . > - Root Cause - > java.lang.ClassNotFoundException: org.apache.struts.action.ActionServlet > at > org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1444) > . > . > 2003-10-25 11:57:14 StandardContext[/diagnosis]: Servlet /diagnosis > threw load() exception > javax.servlet.ServletException: Wrapper cannot find servlet class > org.childhealthcare.diagnosis.servlet.InitServlet or a class it depends on > at > org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:891) > . > . > . > - Root Cause - > java.lang.ClassNotFoundException: > org.childhealthcare.diagnosis.servlet.InitServlet > at > org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1444) > . > . > > > Pretty much one for each of the servlets that I have listed as > load-on-startup.

Re: Unable to find servlet class after reload
Your load on startup is in your applications web.xml file? Are you saying it works fine the first time you start Tomcat? If so, then maybe it doesn't get shutdown propertly, when you restart. Or do you mean just reloading the application? There's supposed to be a patch to Tomcat for fixing reloading issues, but I don't know if this is one of them. I use startup servlets in Struts, but I don't have my app setup for reloading.

Re: Unable to find servlet class after reload
Oscar, Your load on startup is in your applications web.xml file? Yes. Are you saying it works fine the first time you start Tomcat? If so, then maybe it doesn't get shutdown propertly, when you restart. Or do you mean just reloading the application? No, everything works okay when I start tomcat. If I recomplie my classes and redeploy them while the server is running (or otherwise trigger an auto-reload), I get these messages in my webapp's log file, and the webapp is essentially dead after that. There's supposed to be a patch to Tomcat for fixing reloading issues, but I don't know if this is one of them. I'm running 4.1.27-LE with: java version "1.4.2" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28) Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode) on Linux kernel 2.4.20.

Re: Unable to find servlet class after reload
Sriram, Does Struts require initialization by the web app developer ? If so, perhaps you need to somehow ensure that such initialization takes place before you load your servlets ? The first tim I load the web app (i.e. on Tomcat startup) everything works fine. It's only after a webapp re-load that things fall apart. Separately, what exactly do you mean by "reloads cause the errors" ? Does everything work fine when Tomcat is started ? If this is the case, then perhaps you need to try maintaining webapp specific copies of files that you're using from common/lib - stuff like struts, for e.g. Perhaps this is a problem with Classloader hierarchies. I have just about everything in my webapp's lib directory. The only things that are shared are commons-dbcp and commons-pool, which are required for my DataSourceRealm configured in server.xml.

Re: Unable to find servlet class after reload
All, Let me guess: You're running 4.1.27, right? Make sure you've applied the hotfix. Got the hotfix, installed it, all better now. Thanks everyone for your patience and help. I'm sure a lot of people do what I just did and ask for help without doing enough research. :( -chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Stupid question: where can I download this fix? The tomcat download page doesn't give any indication that there's a fix. Thanks so much for the help. I assume that this is a common symptom of the bug that's been fixed? Download the hotfix here: http://www.apache.org/dist/jakarta/tomcat-4/binaries/ Something needs to be done about making it known that the hotfix is available! -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Socket permission in a CGI Script
I'm not a servlets-cgi expert (never used), but I think, if Tomcat runs
with a Security Manager, you can fix the problem by adding the following
in server.policy:
// Give all permission to servlets-cgi.jar
grant codeBase "file:${catalina.home}/server/lib/servlets-cgi.jar" {
permission java.security.AllPermission;
};
If it works then try to only give the socket permission. If you are not
running with a Security Manager, then it's a permission/group OS setting.

Hi all,
I'm trying to execute a CGI script and this Script tries to connect

script can't do this (permission?). I found in the mail archive someone
with the same problem but I didn't found an answer. Anyone has solved
this issue ?
Thanks in advance,

problems with JK2... does max_connections do anything?!
Hi, I have found what appears to be a serious problem in JK2. Am I doing something wrong? I'm tracking down a problem wherein some requests get lost. At first I saw this when doing a large number of requests, but I was able to narrow the problem down to a situation that avoids memory issues. First: Tomcat 4.1.27, Apache 1.3.28, mod_jk2 2.02 I configured Tomcat's JK connector to have a min and max of 3 processors. There is an accept count of 0. What I expect to see now is that up to 3 requests may be served at a time, and anymore will be denied. Instead, I can serve up to 2 simultaneous requests. On the third request, I see the following in catalina.out: Oct 24, 2003 7:05:25 PM org.apache.tomcat.util.threads.ThreadPool logFull SEVERE: All threads are busy, waiting. Please increase maxThreads or check the servlet status3 3 That third request never returns to the client. Now, if I do more requests, I see hit and miss results. If I do 10 simultaneous requests, I'll see two of them succeed, and the rest never return. Meanwhile, I am looking at the JK2 /status/ worker. On the scoreboard, I see (after my first two requests) 2 slots. As I keep making requests, I see the slots increase gradually. By the time I've made 84 requests there are 71 slots, but only 24 requests have succeeded. I've even tried setting the max_connections paramater on my worker to 2, expecting that might do something... no effect. I'm planning to dive into the jakarta-tomcat-connectors source code in order to determine what the problem is here, but I feel as though I must be doing something wrong this is too serious a problem and must affect other people besides me... any ideas?

Re: Unable to find servlet class after reload
Agreed. If you only look in the directory that apache.org links to, you'll see the main download but you won't see the hotfix. Only if you click on the binaries folder will you see it. I now mention it on my HOWTO page: http://daydream.stanford.edu/tomcat/install_web_services.html Maybe others like John Turner can add it as well.

mod_jk 1.2 binary for Linux?
I am unsure if I'm asking this question in the right forum, and while I did a quick look through the archives, I may be repeating a question that someone else has asked and has had answered. If so, I apologize. Someone in my org is trying to put together a development server image (Linux, Apache, Tomcat, JVM, etc.), and needs a clean binary of mod_jk. I pointed him at http://apache.towardex.com/jakarta/tomcat-connectors/jk/binaries/linux/, but it turns out that there's no binary there. It's an empty directory. He and I both did some surfing around, and can't seem to spot a binary anywhere else. Do need to compile our own version of the binary? Is there someplace else I should be looking?

Hi, I sugest that you compile the src, it's not to dificult if you now the steps, download it from here: http://apache.towardex.com/jakarta/tomcat-connectors/jk/jakarta-tomcat-connectors-jk-1.2-src-current.tar.gz to compile (in Redhat 9): $ tar xzf XXX $ cd XXX/jk/native/ $ sh buildconf.sh $ ./configure --with-apxs=/usr/sbin/apxs $ make The binary file will be in XXX/jk/native/apache-2.0/mod_jk.so I hope this helps.

Re: mod_jk 1.2 binary for Linux?
I would recommend compiling it, and it doesn't seem that there's a linux binary available for download. I will be adding JK2 tutorial (only JK1.2 for now) shortly on my site, but looking at it now and John Turner's site, you should be able to figure it out. I find that it's always a gamble using a pre-built connector anyways. http://daydream.stanford.edu/tomcat/install_web_services.html I link to John Turner's site and other helpful sites on my page.

Any exact-mapped (e.g. /foo/bar) or longer prefix-mapped (e.g. /protected/*) Servlet will take precedence over this mapping. However, this mapping will override any extension-mapped (e.g. *.jsp) Servlet.

Re: Experience: Tomcat @ PDA @ PersonalJava 1.2 implementation
You can try searching the tomcat-dev archives (since the post I saw was on tomcat-dev). Can't be bothered myself, but try keywords like: PDA, J2ME, Toaster (a running joke on tomcat-dev, don't ask). Of course, I don't like giving out other developer's email addresses without their permission. However, it should turn up fast enough in a search.
