RE: strange error messages in tomcat log and mod_jk2 log
My production server setup is Apache/1.3.19 (built on HP-UX)mod_ssl/mod_jk/tomcat 4.1.29 on a separate machine I have a moderate loads of 5-10 hits per second and no really big responses (no more than 300k) What I know so far is that this is caused by an attempt by the coyote connector to write in a already closed by the mod_jk socked. The hints I have so far: 1. some proxy servers in the middle might explicitly close lenghty collections 2. lotso ppl blame users pressing stop button in browser!? 3. I follwed some forum thread somewhere (cant remember now) where the guys had observed as a weird bahaviour of Windows IE. They had narrowed the log entry appearances to a hit to a page where the request was submited like this: a href=blah/blah.html onclick=if (boolean_exp) some_form.submit() They were saying that the IE evaluates the onclick and submits the form, at the same time requests the blah/blah.html document, and THEN decides that the blah/blah.html document is not needed and just closes the socket. The guys also were saying that such a behaviour was not observed while tested with Mozzila and Opera browsers. They have been able to avoid it just by making the onclick event handler return false: a href=blah/blah.html onclick=if (boolean_exp) some_form.submit(); return false Though, I have not tested it myself. -Original Message- From: Chris Joelly [mailto:[EMAIL PROTECTED] Sent: 15 2003 . 10:31 To: Tomcat Users List Subject: Re: strange error messages in tomcat log and mod_jk2 log Hi! thanx for your reply. hm. it's a very strange thing. some questions: are you running your application under heavy load? are the responses very big in size? do you use the apache2/mod_jk2/tomcat4 config on a windows nt4 box? does a dialogbox appear on the server with an error message stateing that the apache.exe caused an internal error, and after pressing Ok the apache2 server continues to run? maybe we can find some similarities. we have no idea what direction to look for, and the problem is very critical because a very big application is crashing every few minutes, so a production environment couldn't be setup... :-(( thx, Chris Am Fri, Dec 12, 2003 at 01:46:13PM +0200, Altankov Peter meinte: Hi!

finding hs_err_pid files on windows 2003 as a service with specif ic user
While this is slightly off topic, I wasted enough time on it that I felt it necessary to share with others. I am running tomcat 4.1 as a service on windows 2003(requirement) and I was having a problem with it crashing. Usually it left an hs_err_pid*.log file which pointed to a JNI library that I use. The problem was that I could no longer find these log files(explorer-search) and tomcat seemed to be crashing with no log, error, or anything. The thought occurred to me that maybe the user under which tomcat was running(I recently added this) did not have permission to write the log file. So I found out that the hs_err_pid* will be written to the current directory(system32) and if not successful, to the TEMP directory for the user. While checking permissions, I found all the hs_err_pid* files in the user's temp directory. Apparently even if you are an administrator, a search in windows explorer does not search other user's 'documents and settings'(where the user's temp directory is located). Here I was expecting search to find the files that are there. What was I thinking? I have not found anything about this on the net so I don't know how to disable it. While you can disable the filtering of unknown extensions in searches in windows 2003 explorer, that was not my problem as other hs_*.log files were found in the search results. FWIW, apparently dir /s hs_*.log in a command prompt still works correctly. Charlie - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Manager Valve
Howdy, Ahhvery nice..i was ripping my hair out, I used everything but a comma.Thank you.. No problem. The documentation is really clear on this, so I'm surprised you didn't see it, but that happens ;) Filter eh? Good idea...which is more secure? Same security. The Filter has the advantage that it's portable to any servlet container (servlet spec 2.3 or later), Valve is tomcat-specific. The filter is also more configurable, e.g. if you decide you do want certain locations under the webapp's root to be accessible but others not. But the Valve will perform slightly faster.

Is it possible to configure tomcat to use public / private key pairs that implement the java.security API for authentication a la ssh? I assume it is but haven't found out how yet. I'm using SSL at the moment but I need to implement a higher security environment in the same shape and form as ssh essentially. Just using public private keys. Does this require an applet for the browsers? I'm currently ploughing through what I can find on the web and haven't got that far yet.

RE: Having problems with stored PrintWriter.
Howdy,
Your design is flawed. The writer (whatever it's type is -- certainly
don't use a tomcat-specific type) is invalid after the response is done.
Don't store it, don't try to reuse it. What happens in practice is that
the server closes the underlying writer when the response is sent to the
browser and that's why you're getting the NPE.
What are you trying to do by saving the writer?

REPOST: /devices/pseudo/mm@0:null
While using Tomcat, I have often encountered a problem (a java.net.SocketException) with Too many open files. I understand that to combat this, I need to up the limit on file descriptors in my Solaris 8 system (ulimit command). The system went from 256 - 1024 descriptors, but I still get the error, and in listing the open files, I will see /devices/pseudo/[EMAIL PROTECTED]:null as being used by my Tomcat process - over and over and over. I take it the Tomcat process is writing to null? Is it supposed to do that - or so much of it? Or does this indicate a problem somewhere?

It works well in silent mode, but the only thing is that I get that message box that says that Tomcat will use 'jdk that was found in...', which seems to be the point where the installer stalls until I click ok.

RE: Having problems with stored PrintWriter.

just operate a a pull mechanism.
To create this, there is a piece of javascript embedded within the html outputted to

that function, that user can be notified of events he is registered to.
Perhaps not the way servlets were made to work but anyway!

Re: Having problems with stored PrintWriter.
HTTP is a stateless environment.
You have no way of hanging on to the browser connection from the server.
Usually, if a user has to wait more than a few seconds for a response from
the server you would forward them to a page that refreshes itself every n
seconds via a META-REFRESH tag. Each time it refreshes, it checks the status
on the server.

RE: Having problems with stored PrintWriter.
Howdy, Im trying to create a servlet that is able to push back to the browser rather than just operate a a pull mechanism. To create this, there is a piece of javascript embedded within the html outputted to the browser, so when additional javascript code is written in at a later stage calling that function, that user can be notified of events he is registered to. You can have the JavaScript reload the page from your servlet, i.e. giving the servlet a new request. This is a common solution. Perhaps not the way servlets were made to work but anyway! That's a big but anyway -- probably too big. Unless you are able to come up with a better solution? Depends what your design goal is. A web server pushing stuff onto clients? Not my cup of tea, as you observed that's now how the web works. Clients requests, servlets (as their name implies) and more generally web servers (as their name also implies) serve. How do i stop the response from ending then? I have left the html open at the end so no /html code and I have not closed the output to the browser. Eventually, something will time out. The browser, the server, your firewall, many things can and will terminate the connection.

Re: Tomcat performance on Windows versus Linux
David Rees [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Not enough difference to make it a deciding factor between the two platforms. IMO, Tim's criteria are spot on when deciding what platform to deploy on. Personally, I prefer Unix as I find it easier to setup and administer. Of course, the majority of my experience with Tomcat is on Unix, and not on Windows. That's fine. I never disagreed with Tim's reasons to choose one platform over another. But, as I have already responded, I am not choosing a platform on which to deploy my application; so, arguments as to which platform is better are moot. If you haven't looked already, have a look at the Volano benchmarks (google for it) for some numbers on the scalability and performance of different JVM, but note that those numbers won't necessarily reflect the performance of YOUR application running on Tomcat. Thanks for this tidbit. It is still very early in the process, but scalability of JVMs is definitely of interest to me. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
localhost works, www does not; why?
This may have been asked many times before, but I can't find it, in part because I don't quite know what to search for and in part because it may not even be a Tomcat-specific issue. But it occurs because I'm trying to make Tomcat work, so here goes... (if I'm wrong and the question needs to be redirected, I'm sure someone will politely point it out to me :) I have Apache 1.3.27 and Tomcat 4.1.27 running under Red Hat 9.0 Linux. The two webservers are connected by mod_jk. When I go to http://localhost from the browser on the Linux box, I get Apache's index page. http://localhost:8080 gets me Tomcat's index page. And http://localhost/examples gets me the Tomcat examples directory listing with an Apache port 80 slug at the bottom. When I drill down to the examples themselves, they work. So I know the Apache-mod_jK-Tomcat connection is correctly configured. But when I try it from the live web, using my domain name, I cannot get to the Tomcat pages. http://www.katzenjammer.us gets me my website. http://www.katzenjammer.us:8080 gets me Tomcat's index page, and, again, I am able to drill down into the examples themselves and they work. But http://www.katzenjammer.us/examples and http://www.katzenjammer.us/examples/jsp/index.jsp get me 404 page not found errors. My webserver sits behind a Netgear firewall router, which has been configured to allow ports 80, 8080, and 8009 to get through to the webserver. Can somebody tell me what Im doing wrong? Thanks.

Take a look at the Tomcat logfiles in TOMCAT_HOME/logs Always start there. 2.) Make sure Tomcat can find the javac compiler. Do you have a full j2sdk installed or just a JRE? Tomcat will run with a JRE but won't be able to compile your JSPs without access to javac. If not, go to http://java.sun.com and get a full j2sdk. Is your JAVA_HOME evironment variable set? Type: echo $JAVA_HOME at the shell to verify. It should point to the root directory of your j2sdk. Example: /usr/local/j2sdk1.4.2 Is your JAVA_HOME evironment variable PROPERLY set? Type: $JAVA_HOME/bin/javac at the shell. If you get a Command not found message, it's not. Another way to make sure that Tomcat can see your javac compiler is to run (not just look at, but run) the JSP examples that ship with Tomcat. 3.)

RE: Using jdk... message box
Eugen - I worked on this same issue some time ago. I ended up just documenting (in the installation instructions) to click 'OK' when that dialog comes up. To my knowledge, there is no way around it. Even moving to a newer version of Tomcat will not work - because the newer 5.x versions wont even install in Silent Mode (or at least that's been my experience). They just halt with a dialog saying that they cant find the JVM (on the same setup that a 4.x version will silent install in).

Re: Exception loading sessions from persistent storage
Yes you are...
Tomcat supplies the needed j2ee resources.
When you declare your vPar class, just make sure that you specify that it
implements Serializable:
public class vPar implements java.io.Serializable{
If you have any nested classes do the same for them.

redirecting based on role name
hello everyone, I have a site that uses form authentication thru JDBCRealm. I have my webapp root as /ROOT/ with 3 directories. I have also set up the web.xml file with 3 different security constraints based on the 3 directories in /ROOT/. My questions is, can I redirect a successful login to a specified directory based on the role_name I assigned the user in the mysql database? For example, if I have configured bob with the role_name of admin. Can I redirect his url to /ROOT/ADMIN by retrieving his role_name? Can any one point me in the right direction?

How do you generate a unique number for each request across muliple tomcat instances?
I have an application where I need to generate a unique int for each request that comes in. I've got about 8 Tomcat instances running spread across four machines(two tomcat's each machine). It's pretty simple with one Tomcat, but with mulitple Tomcats it gets tricky. I tried using InetAddress to get the ip address of the current machine and use that to set the range for each tomcat(since the ip address will always be unique), but since I'm using Linux, it'll always return 127.0.0.1 as the ip address, so I can use class InetAddress.

Tomcat 5 Clustering
Hello All:
Please excuse my ignorance, I'm trying to achieve clustering with Tomcat
5I've read the following in the Tomcat 5 documentation:
=
To run session replication in your Tomcat 5 container, the following
steps should be completed:
--All your session attributes must implement java.io.Serializable
===
Okay. I've completed all the other steps (uncomment the Cluster
element along with the valve, and added the distributable/ in
web.xml)I'm trying to code a simple object that implements
java.io.Serializable to store in a session and here it is.
package com.shawmut.session;
import java.io.Serializable;
public class SerializeSession implements Serializable {
public static String testString = ;
public void setString(String stringValue){
this.testString = stringValue;
}
public String getString(){
return this.testString;
}
}
ok.Now I want to put this in the session.
%
if(session.getAttribute(ss)== null){
SerializeSession ss = new SerializeSession();
ss.setString(Booo! And I created my
session on Tomcat 1 Node);
session.setAttribute(ss, ss);
}
%
Whats going on here?.I unplug the patch cord ( docs says it's a bad
idea) from one of the boxes and hit a jsp on the working node that does
the following..and the session doesn't carry over to the working
node
%
if(session.getAttribute(ss)!= null){
SerializeSession ss2 =
(SerializeSession)session.getAttribute(ss);
%
SESSION:%=ss2.getString()%
%
}
%
Basically what I'm looking for is an example of serializing session
attributes as noted above Any Help here will be greatly
appreciated..

Vhosting with Apache 2 jk
Hi all, I have several domains hosted by Apache 2.0.48, and I'd like to start adding JSPs to each domain. I have Tomcat 4.0.16 running on a different host, and am using JK to connect them. Virtual hosting is working on Tomcat, if I go straight to the Tomcat host on port 8080. JK does appear to be forwarding requests over to Tomcat. The problem is, the requests always go to the default domain on Tomcat (webapps/ROOT). It's almost as though the file portion of the URL is getting forwarded to Tomcat, but not the domain. My worker properties is pretty much the sample -- I've included it below. I've also included the lines from my VirtualHost block for the offending domain. Any thoughts? - Bean ... workers.properties # Define 1 real worker using ajp13 worker.list=worker1 # Set properties for worker1 (ajp13) worker.worker1.type=ajp13 worker.worker1.host=66.139.244.188 worker.worker1.port=8009 worker.worker1.lbfactor=50 worker.worker1.cachesize=10 worker.worker1.cache_timeout=600 worker.worker1.socket_keepalive=1 worker.worker1.socket_timeout=300 ... from httpd.conf VirtualHost www.mydomain.local:80 ServerName www.mydomain.local ServerAdmin [EMAIL PROTECTED] DocumentRoot /usr/local/www/data/www.mydomain.local ErrorLog /var/log/apache2/www.mydomain.local/error.log ErrorLog /var/log/apache2/www.mydomain.local/access.log common DirectoryIndex index.html JkMount /main/*.html worker1 JkMount /main/*.jsp worker1 /VirtualHost (The URL I want to go to is htyp://www.mydomain.local/main, since 'main' is the name of my webapp under Tomcat) __ Do you Yahoo!?

You might get a million versions of this answer. Here's one. JK is what you want: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/index.html You'll get an ISAPI DLL that forwards requests, using the AJP protocol (NOT http), to a special service running on Tomcat on port 8009 (this is the default). This is a bit of a nuisance for Windows, since you have to enter registry keys. But the instructions are pretty good and it's not hard.

Re: Tomcat 5 Clustering
download a load balancer
balance.sourceforge.net or a perl balancer called pen (google)
the shut down one tomcat, after initial access, the system will fail over.

Subject: Tomcat 5 Clustering
Hello All:
Please excuse my ignorance, I'm trying to achieve clustering with Tomcat
5I've read the following in the Tomcat 5 documentation:
=
To run session replication in your Tomcat 5 container, the following
steps should be completed:
--All your session attributes must implement java.io.Serializable
===
Okay. I've completed all the other steps (uncomment the Cluster
element along with the valve, and added the distributable/ in
web.xml)I'm trying to code a simple object that implements
java.io.Serializable to store in a session and here it is.
package com.shawmut.session;
import java.io.Serializable;
public class SerializeSession implements Serializable {
public static String testString = ;
public void setString(String stringValue){
this.testString = stringValue;
}
public String getString(){
return this.testString;
}
}
ok.Now I want to put this in the session.
%
if(session.getAttribute(ss)== null){
SerializeSession ss = new SerializeSession();
ss.setString(Booo! And I created my
session on Tomcat 1 Node);
session.setAttribute(ss, ss);
}
%
Whats going on here?.I unplug the patch cord ( docs says it's a bad
idea) from one of the boxes and hit a jsp on the working node that does
the following..and the session doesn't carry over to the working
node
%
if(session.getAttribute(ss)!= null){
SerializeSession ss2 =
(SerializeSession)session.getAttribute(ss);
%
SESSION:%=ss2.getString()%
%
}
%
Basically what I'm looking for is an example of serializing session
attributes as noted above Any Help here will be greatly
appreciated..

Re: How do you generate a unique number for each request across muliple tomcat instances?
Ideally use a string for uniqueness, not an int. For an int is too small across a cluster. To get a unique string, concatenate your IP address with java.rmi.server.UID(), for example: String guid = InetAddress.getLocalHost().getHostAddress() + (new java.rmi.server.UID()).toString()); See the javadocs on UID for more info. -Tim Tom Ly wrote: I have an application where I need to generate a unique int for each request that comes in. I've got about 8 Tomcat instances running spread across four machines(two tomcat's each machine). It's pretty simple with one Tomcat, but with mulitple Tomcats it gets tricky. I tried using InetAddress to get the ip address of the current machine and use that to set the range for each tomcat(since the ip address will always be unique), but since I'm using Linux, it'll always return 127.0.0.1 as the ip address, so I can use class InetAddress.

Re: Tomcat performance on Windows versus Linux
I am about to setup Tomcat under a new Linux 2.6 kernel with 2 Athlon MP processors. Since scheduling, threading, and SMP have been much improved in the new kernel I wonder if it will add to performance. I don't have anything to test the new setup with, but if anyone has good ideas (and by good, I mean easy), as I haven't done any profiling, etc. Oscar http://daydream.stanford.edu/tomcat/install_web_services.html On Mon, 15 Dec 2003, Sean Dockery wrote: Thanks, Tim, for the even handed response. I'm not looking for a business case to choose one or the other, however; it is certain that our customers will be deploying our application on both Linux and Windows (and even Solaris). I'm just looking to find out whether or not OS service (TCP/IP stacks, threads, file I/O, etc...) implementation differences between Linux and Windows have a significant impact on performance and thus should be weighed accordingly. I received a response in email from Peter Lin in which he details his experience (which was very helpful; thank you, Peter). I've read Peter's article about performance tuning and a few other white papers as well, but I haven't really seen anything in the past that focused on OS differences and how those differences might affect the recommended approach to profiling and tuning. My conclusions from my readings so far: Slow java code (i.e.: algorithms) will be slow on any platform; change the implementation to make it faster. Configurable behaviour dependent upon OS services (TCP/IP stacks, threads, file I/O, etc...) should be tuned for the platform on which the application will live.

My guess is that this claim is based upon the supposition that thread/context switches under Linux are faster than under Windows. I find the claim rather dubious because I've never seen data to support the claim, but doubt is not certainty. Is there any evidence that this claim and other component performance differences between the Windows and Linux platform exist and are significant enough to throw my performance measurements out the window. :-) My concern is that I'll profile the application under Windows and tune it, but then find that my gains aren't as significant or maybe even worthless under Linux. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Apache-Tomcat connectors... why??
Hello all, Hopefully I picked a good list to bring this topic up on. There were several candidates. I have spent some time today attempting to perform the non-trival task of configuring communication between the apache web server and the tomcat servlet engine. This seems to be a fairly complicated process involving quite a lot of configuration and some degree of black magic. It occured to me that a simpler approch would be to simply have apache forward requests at HTTP level to a list of slave servers in the form of Cant find this resource!! Can you??. Before apache returns a 404 error it could consult some form of list and ask other servers on the network (tomcat for instance ;o)) to attempt to find the resource via HTTP. I dont see a reason why this would perform particually badly in the most common set up of apache + tomcat. Presumably there is a way to configure apache to do this already (if anyone could point me to the write manaual page I would be grateful), but it doesnt seem to be offered up a simple solution to a complex problem on the tomcat integration pages. My question... why is this solution not mentioned more often given the number of how do i configure mod_jk2?? results on google and would their be any serious disadvantages with such an approch?

Re: Apache-Tomcat connectors... why??
http://jakarta.apache.org/tomcat/faq/connectors.html In a nutshell, tomcat anc apache talk to each via the AJP protocol. The AJP protocol is like the HTTP protocol but more efficient for various reasons. An alternative to having apache talk to tomcat via AJP can also be mod_proxy sounds similar to your situation below. mod_jk and mod_jk2 are both modules written in C to be used by apache (or insert server here) jk2 is a rewrite of jk but for the same protocol. So the configuration of the jk vs jk2 is different. On the tomcat side, it really doesn't know that the apache instance is using mod_jk or mod_jk2. -Tim Wesley Hall wrote: Hello all, Hopefully I picked a good list to bring this topic up on.

RE: Apache-Tomcat connectors... why??
I believe what you are referring to is the ProxyPass Directive http://httpd.apache.org/docs-2.0/mod/mod_proxy.html#proxypass I have used this before, but haven't played with it as a way to reference the app server. If it were that simple, I imagine it would have already been done. I am just getting going with the connectors, but things like parameters, servlets, and the like have their own needs which may require a closer integration with the webserver than can be provided by a simple reverse proxy setup. If all you need is the reverse proxy setup, then perhaps you don't even need the webserver. Just let tomcat serve it all, then all your connector worries are moot.

RE: JDBC from TagSupport
Gotcha, so the datasource gets stuck into a naming directory, and then you can grab it
via JNDI and use it that way.
The benefit being that a sysadmin can change the datasource via server.xml rather than
having you rewrite the code.
Right?

What does this get you? Every example that I have read tells me
that I need to open a JDBC connection just about
the same as I would from any other java application.
What is the purpose of setting up a JDBC datasource in these files? Is
it only good for userdatabaserealm?
The main advantage is that you can use a connection pool like
jakarta-commons-dbcp which saves you a lot of runtime. The second
advantage is that you can configure the connection parameters like db
URL, username, password and the like on the fly without editing java
sources or redeploying your application.

RE: Apache-Tomcat connectors... why??
Thank you Howard and Jim, I will look into mod_proxy. Things seem a little more complicated because I am attempted to integrate with the JBoss tomcat bundle. Obviously the configuration is a little different here and most howto's require a little bit more thinking about as to where to find the files etc... Im not sure about using tomcat as a static content server. Apache has many features that tomcat doesnt as it is designed for this task. It might solve the problem, but the powers-that-be are quite keen on full integration. Im not sure that servlets do require anything extra at HTTP level. Perhaps I am missing something but due to the relative simplicity of HTTP and the fact its stateless I would assume that the servlet container cant require anything extra. From the browsers perspective it is requesting a static resource, by name, from a domain. The proxying route would have the added advantage of not having to reconfigure mod_jk(2) everytime a new web app is added. The browser says Give me /index.jsp, apache says I cant find index.jsp, but i know about THIS http server (tomcat), that might, tomcat says yup, i can do that for you, here it is, apache says Here you go... i found it eventually... all over HTTP. It seems to make a lot of sense to me, but as you say, if this simple solution has not been shouted about, it will mean there is a fundemental flaw... lots of smarter guys than me working on this stuff =o) Thanks again for your help! -Original Message- From: Howard Jim [mailto:[EMAIL PROTECTED] Sent: 16 December 2003 19:34 To: Tomcat Users List Subject: RE: Apache-Tomcat connectors... why?? I believe what you are referring to is the ProxyPass Directive http://httpd.apache.org/docs-2.0/mod/mod_proxy.html#proxypass I have used this before, but haven't played with it as a way to reference the app server. If it were that simple, I imagine it would have already been done. I am just getting going with the connectors, but things like parameters, servlets, and the like have their own needs which may require a closer integration with the webserver than can be provided by a simple reverse proxy setup. If all you need is the reverse proxy setup, then perhaps you don't even need the webserver. Just let tomcat serve it all, then all your connector worries are moot. Jim -Original Message- From: Wesley Hall [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 16, 2003 1:27 PM To: [EMAIL PROTECTED] Subject: Apache-Tomcat connectors... why?? Hello all, Hopefully I picked a good list to bring this topic up on. There were several candidates. I have spent some time today attempting to perform the non-trival task of configuring communication between the apache web server and the tomcat servlet engine. This seems to be a fairly complicated process involving quite a lot of configuration and some degree of black magic. It occured to me that a simpler approch would be to simply have apache forward requests at HTTP level to a list of slave servers in the form of Cant find this resource!! Can you??. Before apache returns a 404 error it could consult some form of list and ask other servers on the network (tomcat for instance ;o)) to attempt to find the resource via HTTP. I dont see a reason why this would perform particually badly in the most common set up of apache + tomcat. Presumably there is a way to configure apache to do this already (if anyone could point me to the write manaual page I would be grateful), but it doesnt seem to be offered up a simple solution to a complex problem on the tomcat integration pages. My question... why is this solution not mentioned more often given the number of how do i configure mod_jk2?? results on google and would their be any serious disadvantages with such an approch?

Hello All:
Please excuse my ignorance, I'm trying to achieve clustering with Tomcat
5I've read the following in the Tomcat 5 documentation:
=
To run session replication in your Tomcat 5 container, the following
steps should be completed:
--All your session attributes must implement java.io.Serializable
===
Okay. I've completed all the other steps (uncomment the Cluster
element along with the valve, and added the distributable/ in
web.xml)I'm trying to code a simple object that implements
java.io.Serializable to store in a session and here it is.
package com.shawmut.session;
import java.io.Serializable;
public class SerializeSession implements Serializable {
public static String testString = ;
public void setString(String stringValue){
this.testString = stringValue;
}
public String getString(){
return this.testString;
}
}
ok.Now I want to put this in the session.
%
if(session.getAttribute(ss)== null){
SerializeSession ss = new SerializeSession();
ss.setString(Booo! And I created my
session on Tomcat 1 Node);
session.setAttribute(ss, ss);
}
%
Whats going on here?.I unplug the patch cord ( docs says it's a bad
idea) from one of the boxes and hit a jsp on the working node that does
the following..and the session doesn't carry over to the working
node
%
if(session.getAttribute(ss)!= null){
SerializeSession ss2 =
(SerializeSession)session.getAttribute(ss);
%
SESSION:%=ss2.getString()%

}

Basically what I'm looking for is an example of serializing session
attributes as noted above Any Help here will be greatly
appreciated..

hmm, on your console or in your log, are the systems finding each other,
ie, do you have multicast enabled and do the nodes actually connect to each
other?
send the logs from a clean run, ie stop, delete logs, start, send logs
