Newbie Question about logging

[ben]

Hi All,

I have just started using 1.4 and using the application log files.

These are great for build errors etc but how can I get my servlets to write
runtime errors to that log (ie ORA errors).

At the moment my catches just write to System.out.println as I hoped the
logs would receive standard err?

Any help is very much appreciated.

[ben]

vernon,
sounds like you havent configured the path for jdk1.3.1_01 yet. thats about
the only thing that i could imagine..if you have configured the path for
both tomcat and jdk1.3.1_01 with : set JAVA_HOME= c:\jdk1.3.1_01..(for
instance)

Troubles with the list: 

value for useBean class attribute invalid

[Ben]

Hi there,
I'm trying to set up a simple beans backed jsp application. I set up 
everything, the bean compiles, the context for the web app is set. But 
after reading around on a number of mailing lists and ruling out the 
most common mistakes (no package, useBean misspelled, no full class name 
used in useBean class= etc.) and after reading the tomcat class not 
found page, I'm pretty sure that something beyond my making a mistake is 
going on...

I greatly appreciate any help, as I am stumped and utterly puzzled at 
this...

thanks, Ben

Re: Search engine friendly URLs

Thanks everyone.

I guess I would have to use the Url Rewrite Filter by Paul Tuckey. I
thought there was a better way of doing this.

Bypass IE's HTTP error messages

[Ben]

Hi

I am using Tomcat 5 and I would like to use my HTTP error pages.
Things are working fine if I use IE and having the IE's "Show friendly
URL error messages" option unchecked. If I enable it, my error pages
don't get displayed.

What can I do to make my error pages display everytime doesn't matter
what settings the users set on their computer.

Thanks,
Ben

Access to j_security_check directly

[Ben]

Hi

How can I deal with users that access to j_security_check directly? I
have used the error-code 400 and redirect the users to the index page
but the system doesn't recognise the them as logged in users.

Any help? Thanks.

Re: Access to j_security_check directly

[Ben]

I created a filter that rejects the "get" request method to the
j_security_check (in my login page I use "post" method). So if the
users access to j_security_check, my filter responses with a resource
not found code.

It seems to be working find.

RealmBase Exception

Hi

I am using Tomcat 5.0.28 and have a custom Realm implementation that
extends RealmBase. When I startup Tomcat I get:

Session ID in URL

[Ben]

Hi

Is there a way to validate the session id?

How do I deal with a situation where a user logged in and found
something interesting on my site and decided to give the URL address
(with jsessionid) of the page to his/her friend? Since the URL has the
session id of the sender, the receiver clicks on the link and will
have access to the sender account details.

How does Amazon.com solve this problem? Their URL addresses always
have the session id. If I go to Amazon.com and copy and paste the URL
address to a new browser, their system will give me a new session id.

Thanks

Same session ID for HTTPS & HTTP

[Ben]

Hi

Is it safe to use the same session ID for HTTP and HTTPS? If not then
how can I deal with a situation where the users disabled cookie and
access to the protected resources? If I don't use the same session ID,
they need to login every time when they access to the protected
resources as the login page uses HTTPS and other pages use HTTP.

Re: is it possible to go to https and return to http?

Hi Derek

Do you append the session to the address when you go to http? Are you
using the same session for http and https? Do you have any concern
about security?

I am facing this problem ATM and would love to hear your advise.

Thanks,
Ben

Tomcat in chroot

[Ben]

Hi

I am trying to setup Tomcat in chroot environment and have
successfully started it up. However, when I run Tomcat in chroot, I
see 10+ Tomcat processes as oppose to a single Tomcat process in a
non-chroot environment. Why is this? Is it normal?

Thanks,
Ben

This application is not currently available

[Ben]

Hi

In my web server environment, I have two Tomcat instances running
behing an Apache httpd 2 server for clustering on the same machine.
When I shutdown one server and use the site as the same time, I
occasionally see the following error message:

---
HTTP Status 503 - This application is not currently available

type Status report

message This application is not currently available

description The requested service (This application is not currently
available) is not currently available.
Apache Tomcat/5.0.30
---

Anyone know what this is happening? May be the settings in my web.xml file?

Thanks,
Ben

Tomcat 5.0 + Apache 2.0 + ErrorDocument

[Ben]

Hi

I would like to have Tomcat handle all the error documents, how can I
do this? At this stage, whenever there is a page not found, I see an
Apache error page. I have already setup mod_jk.

I have this:

JKMount /*.jsp ajp13

In my web.xml, I have this:


404
/WEB-INF/errors/404.jsp


My mod_jk log has the following lines:

jk_handler::mod_jk.c (1952): No body with status=404 for worker=ajp13
jk_handler::mod_jk.c (1952): No body with status=404 for worker=ajp13

Somehow I can't see my /WEB-INF/errors/404.jsp when there is a page not found.

Thanks,
Ben

Tomcat 5 and encodeRedirectURL

[Ben]

Hi

Is it true that Tomcat will ignore the encoding if the request scheme
and URL protocol are not the same? So if I am currently on http and
would like to redirect to https, Tomcat will not encode the https URL
even though the the servername and the port are the same for both
protocols.

This is the reason why the session object always lost when switching
between http and https and vice versa.

What can I do in my app to maintain the session across protocols?

Thanks,
Ben

I have just install tomcat and got it working at http://localhost:8080
I am able to run load <%= new java.util.Date() %> under a jsp file

question:
1) I have create a HelloWorld.java file, where should I put this file and be 
able to run it?
2) if I want it to look for helloworld.xml and have the action being call 
from there, what can I do?
3) do I have to put all the .jar file in the CLASSPATH under autoexec.bat?
This would be a huge line if I also want to put the Velocity template what 
can I do?

my directory:

Re: j_username in session cookie - where did it go?

[Ben Walding]

It was possibly an undocumented (and not part of the spec) feature.

You should just use => request.getRemoteUser()

Where request is passed in through doGet(request, response)  or however 
that works in JSP.

You're probably better off with an application context listener

Re: How to keep track of sessions

[Ben Walding]

You could use an application context listener to write out the sessions 
when the context is shutdown and reread them when it starts up.

I tried to work out how the manager application (part of  the 
distribution) worked (as it knows about sessions), but gave up as it 
looked like to much work and too much poking about inside tomcat.

Re: Testing session time-out behaviour

[Ben Walding]

Although it isn't session timeout specifically, couldn't you just 
invalidate (invalidate() method on session object) the session by going 
to a specific url - eg servlet

Would that emulate the behaviour you are trying to achieve?

Re: Does closing a Connection variable and setting it to null close all of the ResultSet and Statements?

[Ben Walding]

I wrote a booch utility class (fancy name for static methods...)

It has a whole lot of overloaded (Connection, PreparedStatement, 
Statement, ResultSet etc) methods like this... (LOGGER is a JDK1.4 logger)

public static void closeJDBCResource(ResultSet rs) {
try {
if (rs != null) {
rs.close();
}
} catch (SQLException e) {
LOGGER.log(Level.FINE, e.getLocalizedMessage(), e);
}
}

Simplifying (probably over simplifying, I don't see the point in 
unnecessary duplication or nulling local variables) Craig's code down to...

  Connection conn = null;
  Statement stmt = null;  // Or PreparedStatement if needed
  ResultSet rs = null;
  try {
conn = ... get connection from connection pool ...
stmt = conn.createStatement("select ...");
rs = stmt.executeQuery();
... iterate through the result set ...
  } catch (SQLException e) {
... deal with errors ...
  } finally {
closeJDBCResource(rs);
closeJDBCResource(stmt);
closeJDBCResource(conn);
  }

Re: sending login credentials using SSL

[Ben Walding]

You need to look at the user-data-constraint section of  your web.xml. 
Basically it can allow you to control how the server transmits the 
authentication information.

Best Connector for Apache 2x and Tomcat 4x

[Ben Souther]

Can anyone comment on which is the best (in this case, best means easiest
not fastest or most flexible) connector to use for Apache2 and Tomcat4x?
I've used mod_jserv a couple years ago.
Also, if someone could point me to a well written HOWTO for integrating the
two, I would be most grateful.

Thanks

Re: Best Connector for Apache 2x and Tomcat 4x

[Ben Souther]

Thank you,

Best IS relative. That's why I explicitly stated my needs in parenthesis.
:-)
I'm running on RH Linux 7.1

The reason I wanted to integrate the two is that I don't want to run tomcat
as the root user but I do want to use port 80 instead of port 8080. I know
that Apache gets started by the root user but then forks off all other
processes to the user "nobody".

If you know of a way to configure Tomcat to bind to port 80 without having
its processes run by the root user, this would eliminate the need for me to
integrate. It isn't a site with a lot of traffic or static content.

Re: Best Connector for Apache 2x and Tomcat 4x

[Ben Souther]

I see what you mean about this issue showing up a lot.
This wouldn't be the case if there was some documentation for this on the
apache site.
I've just started going through your HOWTO and it looks well written. You
might want to consider contributing it when you've got it updated.

Re: Best Connector for Apache 2x and Tomcat 4x

[Ben Souther]

John,

I've followed the directions in your howto and the two don't seem to be
connecting.
The only clue I can find is in the Catalina.out log:

mod_jk location: libexec/mod_jk.so
Make sure it is installed corectly or  set the config location
Using 
Starting service Tomcat-Standalone
Apache Tomcat/4.0.4
Starting service Tomcat-Apache
Apache Tomcat/4.0.4


Is this something you've run into before?

Thanks
-Ben

Re: question about localhost

[Ben Walding]

0.0.0.0:8080 means that Tomcat is bound to all interfaces on port 8080

Some things to look at

Have you added a proxy?  (need to add a proxy bypass for localhost)
Does ping localhost end up pinging 127.0.0.1 (your hosts file might need 
updating)?
Can you telnet to 127.0.0.1  port 8080 and get a connection?

Replacement 401 pages

[Ben Walding]

Greetings all,
Maybe someone can answer the following conundrum for me!

I've replaced my 401 page with a servlet reference using the error-page 
section of the web.xml. I'd like the servlet to display different 
content based on what was accessed. At present I have to use javascript 
(document.location.href) to do this at the client end.   Surely there is 
a better way!?!

The servlet "works" and forces authentication (once I'd added a Realm 
header and 401 status code), however I can't detect the cause of the 
authentication in the authentication page servlet ("I" know what 
resource caused the authentication page to be called, but the servlet 
doesn't seem to have any simple way to determine this). All I need is a 
header being passed in on the request object, but if there is a spec 
defined way to do this... I'm all ears...

Since it isn't using a redirect (just some internal shenanigan), there 
doesn't seem to be any headers to help me out.

Cheers,

Ben

Re: Solved! Re: Basic authentication and custom 401 Not Authorizederror page

[Ben Walding]

It can be made to work...

Put the error-page directive in as per web.xml spec

On the jsp / servlet it points at,

response.addHeader("WWW-Authenticate", "BASIC realm=\"" + realm
+ "\"");
response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);

and then write custom page

And it will challenge (well it did for me...)

No need for filters or any of that jazz.

Re: Starting and stopping Tomcat as non-root

[Ben Souther]

How would "Not allowing non-root users to bind to Ports <1024" result in
breakins?
The only way I could see that happening is if a lazy Unix admin just ran
everything as root.
In that case, you certainly can't blame the OS.

Re: tomcat as nt serice

[Ben Souther]

One workaround might be to create a batch file that starts tomcat when the
NT box boots up.
You can alter the catalina.sh script in /conf to use javaw
instead of java, you eliminate that persistant DOS window hanging around on
the machine. All output with Tomcat 4x gets directed to catalina.out in the
conf directory, so you won't miss the console window too much.

Re: Tomcat 4.1.10 startup exception

[Ben Walding]

I had the same problem... in my case, the validator for the server.xml 
(or the fragment for your application) seems to have become a lot tighter.


I chopped bits out of my server.xml fragment until it started up and 
tracked it down to an  tag... I hadn't set the data type on 
it...

YMMWV (will vary!)

(This was a switch from 4.0.4 to 4.1.9, but I'd imagine 4.1.10 is similar)

Re: Permission denied trying to connect tomcat to port 80...

[Ben Walding]

Might be best to post the dump of your error message.

Although from the sounds of it, it might be that your catalina.sh / 
startup.sh is not set for execute

Try chmod a+x catalina.sh

Then
./catalina.sh run

See if that helps

Does it work if you pick a port like 2343 or some other random unused

Re: onLoad Servlet

You're probably searching for the wrong thing!

Autodeploy oddity (bug?) in 4.1.10 (TomCat deploys same webapp to2 contexts instead of 1)

[Ben Walding]

I've found a minor oddity when using auto deployment in 4.1.10.



Take a simple web application (called montage),  create a 
montage_prod.war and montage_prod.xml for it and copy them to the 
webapps directory.  However before doing that, change the  path i.e.



Restart tomcat.

TomCat proceeds to merrily deploy montage_prod.war to /montage and this 
context works.

However it also deploys montage_prod.war to /montage_prod and this 
context doesn't work properly (I dispute whether it should even exist at 
all).  It appears to be missing the environment settings from 
montage_prod.xml.

Admittedly this won't affect many people and I only noticed because I've 
started using the built-in TomCat manager.


Is this intentional behaviour?

(I realise I can rename montage_prod.war to montage.war  and similarly 
for the xml, but that isn't really the point).
(I've looked at 
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/host.html#Automatic%20Application%20Deployment,
 
but it skates around this question)

Cheers,


Ben

Re: Where to place JAR file???

[Ben Walding]

Anything under WEB-INF is invisible to a web user, it's just the way 
things are.
Hence, I believe that you are going to need to put the library.jar in 
two places, once in the WEB-INF/lib and once in the same dir as 
applet.jar (but not under WEB-INF)

Re: Autodeploy oddity (bug?) in 4.1.10 (TomCat deploys same webappto 2 contexts instead of 1)

[Ben Walding]

Using the manager, I deployed the application (removed it from webapps 
dir first and restarted tomcat).

/montage was then available (no /montage_prod)

Stopping & restarting tomcat made /montage disappear as expected.


It's seems like the auto deploy system doesn't check if you had a 
context descriptor xml file for your .war file.

Re: threads best practice

[Ben Walding]

I can't imagine why you'd have problems with your classloader.

In any event, I prefer to use context lifecycle events myself.

See http://www.onjava.com/pub/a/onjava/2001/04/12/listeners.html?page=1

You might want to post more details about your classloader problem as it 
is possibly only a minor problem.

Re: Source code directory / deployment directories / CVS repositoryt ree (URGENT)

[Ben Walding]

Probably a good idea to read through 
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/source.html.  

I personally don't like having TomCat looking into my source area as I 
prefer to deploy for development like I do for production.  To this end 
I just create a WAR file and use the manager webapp to stop and start 
the context, as this is fully scripted it takes around 9 seconds for our 
application.  I also prefer to have my server.xml clean of context 
information eg (TomCat 4.1.* only).

%TOMCAT_HOME%/webapps/.xml  (the  node that is normally in 
server.xml)
%TOMCAT_HOME%/webapps/.war

And the use Ant's  to create the customised Context 
xml on the fly.

Re: Hosting services

Have you looked at assortedInternet.com?

They don't let you stop Tomcat but you can use the manager app to restart
your app which would allow you to customize your web.xml file.
They are running Tomcat 4x (not sure whether it's 4.0.1 or 4.0.4) and
Postgresql/mySql.

Best way to redeploy a war file?

[Ben Rometsch]

Hi There,

Apologies if this has been asked before. I'm running tomcat 4.0 in
production and looking to move up to 4.1. Can someone explain the
simplest and least intrusive method of redeploying a war file to update
an application?

At the moment my method (in 4.0) is:

- Remove /webapps/app.war
- Upload new app.war to /webapps
- Shutdown tomcat
- rm -Rf webapps/app
- Startup tomcat

Which all seems a bit over the top. Is there a simpler method that does
not involve taking tomcat down?

In 4.1, I've tried using the http manager app to undeploy and then
redeploy the application, but the undeploy does not seem to work. I
always get the error:

FAIL - Cannot remove document base for path /outreach

Is this a bug? I've tried it on the /examples app as well and I get the
same error. 

Many thanks in advance,
Ben Rometsch

Re: Bug in 4.1.10?

[Ben Walding]

You haven't done something odd with file permissions / quotas have you?

I can't recall offhand what user the service runs as, but you could try 
setting it to run as the same user as you are logged in as.

We are using TomCat 4.1.10 on Win2K SP3 with JDK 1.4.0_01, and JSPs do 
compile (well the /index.jsp  which is the only one we use).

Can anyone Undeploy an Existing Application in 4.1.10?

[Ben Rometsch]

Hi,

I am getting this error in both Windows XP and Gentoo Linux:

http://localhost:8080/manager/undeploy?path=/outreach

Always results in:

FAIL - Cannot remove document base for path /outreach

With, curiously, the following being logged:

2002-09-12 12:37:13 Manager: undeploy: Undeploying web
application at '/outreach'

I can't find any error messages in any of the log files. Running 

http://localhost:8080/manager/list

Shows that the application is still there. Has ANYONE managed to get
this working in 4.1.10? Otherwise, I'll submit a bug...

Thanks,
Ben

RE: Can anyone Undeploy an Existing Application in 4.1.10?

[Ben Rometsch]

Yes I have. You can't undeploy an existing application through that app.
You  can only remove an application, which is different. 

I'm pretty sure the
http://localhost:8080/manager/undeploy?path=/ component is not
working - has anyone managed to get it functioning properly?

Tomcat4-4.1.10 Startup Issue (LINUX)

[Ben Hamilton]

Installation:
I've loaded java from the binary install application for j2sdk from the
java.sun.com site. I've modified the /etc/profile to include the
CLASSPATH listed below.
In a directory with three rpms:
tomcat4-4.1.10-full.1jpp.noarch.rpm
tomcat4-admin-webapps-4.1.10-full.1jpp.noarch.rpm
tomcat4-webapps-4.1.10-full.1jpp.noarch.rpm
I've issued the following command.
rpm -i *.rpm
Results in an installation without errors given.

I've created the /etc/java.conf with the line:
JAVA_HOME=/usr/java
/usr/java/bin is the bin directory from the jdk that contains java,
javac and the rest of the binaries for the jdk. /usr/java/lib/ext
contains the .jar files distributed with the jdk and jre.

PROBLEM:
When issuing the command 'tomcat4 run' the error below is generated. To
me there seem to be two problems: 1) "ERROR reading
/var/tomcat4/conf/server.xml". I've made sure that the tomcat4 user owns
the files in /var/tomcat4 and /etc/tomcat4 - besides file permissions
what does tomcat need to read the file? 2) The remaining portion of the
error seems to indicate something in the startup of Catalina cannot find
a class or a file that is apparently critical to a smooth launch.

Are there additional files to modify besides:
/etc/java.conf
/var/tomcat4/conf/tomcat4.conf
?

running "nmap -p 8000-9000 localhost" produces no open ports at various
points during the pause (about 5 seconds) before the errors are
generated.

I know next to nothing about java although in the last few days I've
read through the user archives and have found messages that point to
similar problems on a win32 platform. The results of those posting are
unsolved. I'm hoping this is a configuration issue that I'm just not
getting straight. Any help is appreciated.

Thanks in advance,
BenH

Re: How to access the request that triggered FORM authentication?

[Ben Walding]

(Courtesy of Tim Funk)

See section 9.8 of the spec:
A web application may specify that when errors occur, other resources in 
the application are used. These resources are specified in the 
deployment descriptor. If the location of the error handler is a servlet 
or a JSP, the following request attributes can be set:
- javax.servlet.error.status_code
- javax.servlet.error.exception_type
- javax.servlet.error.message
- javax.servlet.error.exception
- javax.servlet.error.request_uri

In your JSP or servlet, use request.getAttribute("...") for any of the 
above to get more details about the error. Then you can forward() or 
"whatever" based on your business logic.

How do you have multiple server.xmls? Do you use the same startup
script?  Did you use a specific How-To?

Thanks,

Re: installing and running tomcat 4.1 on linux

[Ben Walding]

I haven't used 4.1 as an RPM, but with 4.0 it was just a matter of

service tomcat4 start

Most of the files live in /var/tomcat4 if I remember correctly.
Check out /etc/init.d/tomcat4 for more details

Re: Postgresql DataSource Tomcat 4.1 SQLException

[Ben Walding]

The JNDI namespace you want is
java:comp/env

and not java:/comp/env

But I'm not sure if is the cause of the problem.

Re: How to use Port 80?

[Ben Walding]

You don't want to change /etc/services as it is simply a directory of 
mappings between well known service names and ports.

Tomcat runs as the user tomcat4 on RedHat 7.x.  This user is unable to 
bind to port 80.  People have had success with changing the user to 
root, but this is generally considered a bad way of doing things. 
 You'll want to check the mail archives as this has been discussed quite 
a bit.

Re: How to use Port 80?

[Ben Walding]

You can set up a port forward / filter such that traffic that comes in 
on port 80 gets filtered through to port 8080

The other options is to use Apache out the front on port 80 and then 
mod_jk / jk2 / mod_webapp to connect tomcat into apache.

I can't recommend one or the other for these as I don't run in either 
configuration.


It's all a big game!

Re: compiler runs out of memory

One of the bugs fixed in JDK 1.4.1 is the leaking of memory in the java 
compiler.  This may fix the memory leak that you are seeing...

RE: Running multiple tomcat instances ?????

[Ben Ricker]

If that script works, then great.

A less elegant way to do it would be to utilize pgrep. Do a man on it
(not sure what platform you are running on). You can pgrep for the
earliest PID that was run with a number of options. I use it for a Jserv
installation and it works quite nice.

I have not tested it with Tomcat, though.

Good luck,

Re: Deploy or install .war

[Ben Walding]

Once the war file is in the webapps directory it will auto-deploy when 
you restart TomCat.  I realise this doesn't truly answer your question, 
but it should fix your problem.


I'm presuming you are using a 4.1.x version (4.0.x is pretty much the 
same, but not quite as nice).

Problem with mod_jk.so

[Ben Ricker]

I downloaded the binary of mod_jk.so from Jakarta's downloads in
/builds/jakarta-tomcat-connectors/jk/release/v1.2.0/bin/linux/i386. I am
running Apache 1.3.26 with Tomcat 4.05 on Red Hat Linux release 7.1
(Seawolf). The binary is compiled for 7.2, however. That may explain the
following error when trying to start Apache:


[root@dev bin]# ./apachectl configtest
Syntax error on line 208 of /usr/local/apache-new/conf/httpd.conf:
Cannot load /usr/local/apache-new/libexec/mod_jk.so into server: 
/usr/local/apache-new/libexec/mod_jk.so: undefined symbol: ap_ctx_get

Any ideas? Do I need to upgrade gcc, possibly? What do the binaries rely upon?

Thanks in advance,

Ben Ricker

No EAPI...As the download site says:

  * mod_jk-1.3-noeapi.so is for Apache 1.3.x without mod_ssl

I do not have mod_ssl installed. Verified that through httpd-l.

This may add some info: I compiled Apache with ApacheToolbox. The
modules are static but it has DSO support in it. Then again, I would
expect an error much earlier in the load process then an undefined
symbol.

I cannot guarantee that it IS the 1.3 connectorthe filename suggests
it is.

Re: Load balancing + replicated sessions

[Ben Ricker]

See http://www.theserverside.com/resources/article.jsp?l=Tomcat. you can
do in memmory session replication across JVMs through TCP.

Just to let everyone know, I downloaded John Turner's mod_jk.so and the
problem went away (have not finished testing, however). The URL is:

Error 400 getting thrown

[Ben Ricker]

I am having a problem setting up a Tomcat installation using multiple
Tomcats (two to be exact) being load balanced from one Apache. Mod_jk is
being loaded correctly. I created a file called index.jsp with the
following code:




<%= request.getSession().getId() %>
Tomcat 1



When I access index.jsp, I get a white page in the browser. Here is what
I get in the mod_jk log in debug mode:

What exactly is the Error 400 showing? Error 400 is a "Bad Request".
Below are snippets of some conf files. Let me know if I need to show
anyone the server.xml file.

Dangit...forgot to include that:

hostname:8080/index.jsp

Apache is listening on 8080 as I test this new setup. I have Tomcat
listening on 80 now.

Good call! I missed that one. Fixed it and it made no difference

NullPointerException

[Ben Monnahan]

Hi all,

  Does anyone have any ideas why I would get a NullPointerException when
instanciating a class inside of a servlet when the class works fine when
run as its own program?  I am using Java 1.4.0_01 from Sun and Tomcat
4.1.10 with the invoker servlet disabled.

  On a separate but somewhat related note; I have been having all sorts of
problems with servlets in Tomcat.  Am I alone in this or is it just a
complicated system?

Thanks,
Ben Monnahan

Problem with JK 1.2.0 docs?

[Ben Ricker]

I am confused by the build process for mod_jk 1.2.0 on a Redhat 7.3
server. From the 'BUILDING' text file, it says:

"use configure and indicate Apache 1.3 apxs location (--with-apxs)
use make
copy the mod_jk binary to the apache modules location"

Now, after doing a 'make' there is no binary in the top-level directory
with the configure script (i.e.,
jakarta-tomcat-connectors-jk-1.2.0-src/jk/native). So I went into
jakarta-tomcat-connectors-jk-1.2.0-src/jk/native/apache-1.3 and I see
the following files:

[root@javatest2 apache-1.3]# ls  -l
total 1556
-rw-r--r--1 root root  120 Sep 26 04:34 libjk.module

-rw-r--r--1 root root   101844 Oct  9 11:28 mod_jk.o
lrwxrwxrwx1 root root   15 Oct  9 11:28 mod_jk.so -> mod_jk.so.0.0.0
lrwxrwxrwx1 root root   15 Oct  9 11:28 mod_jk.so.0 -> mod_jk.so.0.0.0
-rwxr-xr-x1 root root   326225 Oct  9 11:28 mod_jk.so.0.0.0

So which is the binary? Mod_jk.so is a symlink. Should I just move
mod_jk.so.0.0.0 to the apache directory as mod_jk.so? The documentation
is very vague on this point. I get around it by doing a 'make install'
in the native directory and it installs a symlink to the the libexec
directory of Apache.

Reloading w/ Manager on cluster?

[Ben Ricker]

I have a setup with 2 APache servers (1.3.27 on Redhat 7.3) talking to 4
tomcats clustered across two SOlaris 8 boxes running Tomcat 4.0.5. We
have a load balancer across the web servers and, of course, mod_jk 1.2.0
doing the load balancing across the Tomcats.

We have a QA environment where I want the abilty to reload the apps
through the manager application. We cannot do it through the Apache load
balancer because you cannot quarantee what Tomcat you are going to talk
to at any given request.

I thought of having Tomcat use its embedded web server on 8080 and 8081
on each Tomcat server and have the developers call those for reloading,
but they would have to do that 4 times for every reload. Plus, if we
scale to a bigger cluster, the problem becomes worse.

I do have a script that stops and restarts all of the tomcats from a
central location, but is there any danger to be restarting Tomcat
frequently? Has anyone worked around a cluster for the management app?

Thanks,

Ben

RE: Reloading w/ Manager on cluster?

[Ben Ricker]

The script is rather rough right now, but it is simple. I use ssh to
call the tomcat startup script like so:

ssh hostname /etc/init.d/tomcat stop

Here is the contents of the startup script. I have two Tomcat
directories, /usr/local/tomcat1 and /usr/local/tomcat2. I have them
sharing a centralized webapps directory in /usr/local/webapps. I run the
tomcat processes with an unpriveledged use, 'tomcat'.

Re: Using daemontools to supervise Tomcat

[Ben Ricker]

I tried to get Daemontools running for Jserv (which is pretty similar)
and had no luck. My guess is that you might be able to get it to work if
you pass all the env variables using daemontools and just launch java.
However, since java is not a normal daemon, you will probably need
fghack to do it. 

I myself gave up; the thought of creating all those environment
variables was just too much, so I just rolled my own PID monitor whcih I
am porting to Tomcat. Basically, it will grep out the PID and write to a
file which I watch with a cronjob process.

HTH,

Ben Ricker

Actually there is. I use a -Dafoo to give the process a unique
identifier. This sets a marker on the process but does nothing for the
JVM itself. To find a process ID, I would use 'pgrep -f foo' and the PID
is returned (this is on Unix, btw). Also , when you do the '-Dafoo' as
the first "arg" to the JVM, it appears in 'ps -ef'.

Here is how I do it: I setup the java command line like so:

/usr/local/jdk/bin/java \
-Da=Ftp \
-cp $PROP_DIR:$EXT_INT_JAR:$NET_COMPONENTS_JAR:$LOG4J_JAR \
com.usrx.extinterface.ftp.FTPService $PROPERTIES_FILES \
>> $LOG_FILE 2>&1

Then I do this:

pgrep -fn  Ftp > $PIDFILE

Technically, you do not need the 'n', as that denotes the newest
process. You can get by with just the -f.

Finally, I run the following script through cron every minute. The
variables should be self-explanatory. For security reasons, I cannot
divulge the whole setup. Basically, this snippet below monitors 7 JVMs
and if they are not running, restarts them. It has worked flawlessly for
a long time.

-Begin Snippet--

for i in $*
do
eval BASEDIR=$`echo BASEDIR_$i`
eval PIDFILE="$BASEDIR/$`echo PIDFILE_$i`"
eval PNAME=$`echo PNAME_$i`

You will have to use fghack because java does not act like a daemon
usually does. A daemon usually puts itself into the background after
executing. Java does not. That is what fghack does. Unfortunately, as
the web site for daemontools says, if you use fghack, it will disable
your ability to use svc and will make all the other commands pretty
useless. Daemontools works great with daemons that act like daemons; it
works like hell with programs that don't.

Re: Unspecified NoClassDefFoundError

[Ben Monnahan]

I'm using VisAD to do some visualizations.  What I'm doing is taking a
snapshot of the current display and writing it to an image.  Since this is
in a servlet, there isn't any real display.  According to the VisAD list
for the case when you don't need a real display you can use and offscreen
renderer.  So I think it is painting the component to some sort of virtual
screen and then it is going to grab that image and save it to disk.

Unfortunately there isn't an exception to go with it.

I just found a post about java 1.3 on linux having problems with offscreen
rendering.  I'm using java 1.4 so this shouldn't be a problem right?  If
the VisAD code was written for java 1.3 would I still have problems even
though I'm using 1.4?

Thanks
Ben

Hi all,

  I am getting NoClassDefFoundError in my servlet, but it doesn't tell me
which one it couldn't find.  I'm guessing its a problem with
GraphicsEnvironment.getLocalGraphicsEnvironment().  I tried a search on
google, but it didn't turn up anything.  Does anyone know what might be
wrong?  Here is a stack trace:

java.lang.NoClassDefFoundError
at java.lang.Class.forName0(Native Method)

Re: Connecting Apache with remote Tomcat

[Ben Ricker]

I run mod_jk 1.2.0 and I do not need to recycle Apache when restarting
Tomcat. I did notice a lag of up to 2 minutes after restarting Tomcat
where Apache will not take requests. I think this is due to Tomcat
restarting itself and classloading. Maybe you do not wait long enough
after restarting Tomcat before you retry a connection?

FYI, I am running two Apache 1.3.27 on Redhat load balancing across 4
Tomcats on two Solaris 8 servers.

I am wondering about the kernel version here; you have rather old
kernel, a version which is considered unstable. I would suggest
upgrading the kernel, especially since you have SMP.

This is just a small suggestion.anything in the logs?
