cluster problems: memberDisappeared errors

[Joshua Szmajda]

I'm using the cluster fix patch on 5.5.9 (from 
http://issues.apache.org/bugzilla/show_bug.cgi?id=34389) with 8 hosts 
clustered together. I was seeing alot
of memberDisappeared errors before I applied this patch, now I'm still 
seeing them, but with more detail.

Here's an example error from catalina.out:

any ideas? I'm thinking there's something wrong with my multicast setup, 
but everything was working fine this morning... The servers are running 
RHEL3, all 2 way AMD64 machines with 4Gb ram each. They each have two 
network interfaces, each eth0 is connected to one gigabit switch, each 
eth1 to another (internal) gigabit switch. I don't think I should be 
hitting any network bottlenecks.. ? There is alot of load on the site 
being served in general, but no big jump in hits today.


Should I be using a fastasyncqueue? What are the tradeoffs in Sender modes?

Thanks in advance!

Re: tomcat clustering

[Joshua Szmajda]

Awesome!
I think though since I need this functionality now, I might go with
JGroups' DistributedHashtable system. It's basically what I need right
out of the box.

Thanks, and good luck! I'll be looking forward to that functionality.

tomcat clustering

Hey all,

Is there a way to get the cluster system to replicate ServletContext
scope variables between cluster members? If not, is there a good guide
to writing Multicast sockets somewhere?

Thanks alot!

JBoss (Tomcat?) problems with mod_jk2, httpd, and UTF8 form submissions?

[Joshua McCulloch]

I posted this on the JBoss forums and had no
responses. 
Although our environment is JBoss, I believe it would
also occur in Tomcat, although maybe not in latest
build?

---

We're using JBoss fronted by Apache HTTPD 2.0.52 with
mod_jk2. Found a strange bug. When a HTTP parameter
(in this case, it is a submit button) is being posted
with a UTF-8 character (0xc3b3, Latin1 0xF3, lowercase
o with acute). This is actually being posted as UTF8
(0xc3b3), and either JBoss or more likely Tomcat is
not converting these two bytes to a single character
(\u00f3). I want the value to be sent in UTF8, so this
is correct. The problem is that somewhere along the
line the data is not being interpreted as UTF8 and
being read as two characters.

If I use a GET, it will still fail. However, if I
remove Apache from the picture, and use the
URIEncoding attribute as follows:

Code:

   



It will work with a GET. Still will not work with
POST. I switched back to using Apache, and changed the
AJP connector to also use the URIEncoding attribute.
This fixed the GET, but POST is still not working
properly.

Other than changing our forms to use a GET, does
anyone know of a solution?

We're using JBoss 4.0.0, Httpd 2.0.52, and mod_jk2
(not sure of exact version).

Please let me know if I need to describe anything
further.

Any suggestions?

Thanks,
Josh

Re: Tomcat, Apache connected in interesting way

[Joshua Szmajda]

Both are on the same server, yes. They are however listening on 
different IP addresses. If needed, you could set the tomcat http 
connector to listen on a different port and adjust the rewrite rule 
accordingly.

As far as SSL goes, the SSL encryption will be in place from the client 
to apache, but not from apache to tomcat. This is ok because apache and 
tomcat are both in the same trusted subnet (in fact, on the same 
machine). If that weren't the case, you could alter the rewrite rule on 
the SSL vhost to send requests to tomcat's ssl connector, thereby 
encrypting all connections.

-Josh
Joshua -
Are tomcat and apache running on the same server? If so, it appears 
from what you have here that they are on the same port...so...what am 
I missing?

Also, how do you handle .jsps and .dos that need to be handled by 
Tomcat securely (using SSL). This seems to pass them all off to the 
non-secure version. Would it just be a more complex RewriteRule that 
tests for https vs. http?


Thanks,
Matt

Tomcat, Apache connected in interesting way

[Joshua Szmajda]

Hi all,
I run a pretty high traffic site using Tomcat. We've gone through a 
number of configurations in the past, and I wanted to share with you the 
newest setup that we're using. It's a bit unorthodox perhaps, and I was 
wondering if anyone could think of possible problems? It does seem to be 
the fastest and most stable setup we've had yet.

Previously we've used Apache and Tomcat connected through jk1 and jk2. 
Also we've run direct to tomcat's http connector. JK1 was ok, but very 
slow. JK2 was fast (using unixSocket communication), but very buggy and 
crash prone. Tomcat alone was good, but it lacked some advanced apache 
stuff we wanted (Mostly URL Rewriting and good SSL handling).

After reading about the upcoming mod_proxy ajp connector for apache 2.2, 
I had the idea to use stuff that's in the current RHEL apache 2.0 
release to accomplish what I feel to be a similar effect. We've set up 
apache to reverse proxy requests for .jsp and .do (we're using struts) 
to tomcat's standard http connector.
From the httpd.conf:


 Order deny,allow
 Allow from all

ProxyRequests off
RewriteEngine on
RewriteRule ^/$ http://128.121.26.205/index.jsp [P,NC]
RewriteRule ^/(.*.jsp.*)$ http://128.121.26.205/$1 [P,NC]
RewriteRule ^/(.*.do.*)$ http://128.121.26.205/$1 [P,NC]
This allows apache to process additional rewriting things (I left them 
out) and also to serve images and other static content. I felt that 
apache would be better at handling static content than tomcat in 
general, so this will be an overall speed improvement.

Anyway, any flaws here I should be aware of? Comments? Thanks!

Re: AW: Tomcat 4.1.24 + Security Manager + weird Exceptions

[Joshua Szmajda]

I'm experiencing this same issue. I've got Tomcat 5.0.27, Apache 2.0.46,
and jk2 version 2.0.4. Has there been any solution? It occurs primarily
under heavy load.
-Joshua Szmajda
We've got a similar issue, though this in on Linux and using channelUnix/JNI instead 
of normal tcp channelSocket.
We're using Apache2/mod_jk2 (built from tomcat-connectors-1.1M1).

On heavy load, there are over 3000 sockets open by one Tomcat/JVM, they don't seem to 
go down again too while Tomcat is running.
(since File Descriptor limit on Solaris is lower normally (1024 or summat i think) 
this would cause us heavy problems there too)

The Tomcats and Apache are restarted during the night to free up Memory, so socket 
count goes down then.

However the application doesn't seem to be affected by this.
In catalina.out there are many errors like this:

JK2 possible JNI problem? nativeDispatch exceptions

[Joshua Szmajda]

Hi All,
I've got Tomcat 4.1.20 and Apache 2.0.46 running on Red Hat Enterprise 
Linux AS 3. I'm using the jk2 connector (connectors version 2.0.4) with

I'm running a very high traffic site and so I was wondering if perhaps 
this was due to file locking collisions on the socket? I'm not sure 
there. This didn't used to happen when I was using regular domain 
sockets. I do need the unixSocket channel however, as it's proven to be 
much much faster.

I've tried commenting out the line that writes the first line, but that 
only seems to exacerbate the number of exceptions. I also was able to 
diminish the number of exceptions by changing the shm file from anon to 
a real file on the system. I'm thinking this is slowing down the JNI 
somehow? (leading me back to the collisions theory).

Any help is greatly appreciated! Otherwise I'm left with trying to read 
the code and learn JNI =/

Thanks Again,

RE: context.xml - what's the secret?

[White, Joshua A (HTSC, CASD)]

No problem.

I am using the "org.apache.catalina.ant.InstallTask" ant task.

As far as I know, this task does not copy the context XML into
$CATALINA_HOME/conf/Catalina/localhost.  Should it be doing this?  In fact,
the $CATALINA_HOME/conf/Catalina directory does not exist.

Suggestions?

Ok, this may sound like a rather obvious question, but how are you using 
the Ant task to install ? Are you using the deployer, or a custom ant 
task ?

Also, when you deploy your web application, does it copy the context XML 
into $CATALINA_HOME/conf/Catalina/localhost ? If it does not, then I 
suspect something is not working properly with the ant build file 
(everytime I write something like this, I get plenty of negative 
responses -- but at least, Joshua, you'll get a lot of information !)

Hi Joshua,

If you're using a war file, then you should place the  fragment 
inside META-INF then deploy it. If you have already deployed the web 
application (that is, it is either already expanded inside your web 
application directory, or the directory was manually created and your 
servlets and JSPs reside inside there), then the context's XML file goes 
into $CATALINA_HOME/conf/Catalina/localhost/

And remember that it should be given the same name as your web 
application (that is, if your web application is called 
'MyWonderfulApp', then the name of the XML file should be 
MyWonderfulApp.xml. Not context.xml.

I spent the whole of last weekend figuring this out ... sigh !

Subject: context.xml - what's the secret?


Hello all,
 
Let me first say that I am using Tomcat 4.1.30 and have an existing
application that is working properly.  I decided that I would like to
explore putting the context element for my web application in a
myWebapp/META-INF/context.xml file instead of in my server.xml file.  The
existing configuration currently works and defines both a dbcp connection
pool and a mail session.
 
After removing this context element from my server.xml file and placing it
into the context.xml file, my application no longer works.  What did I miss?
I am using the ant install and deploy tasks to deploy/install this simple
application.
 
I receive the following exception (keep in mind that my previous
configuration works and that my JDBC driver is in the common/lib dir):
 
org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of
class '' for connect URL 'null', cause:

apache/Jk problems

[Joshua J. Cox]

Converting some apache/tomcat systems from Webapp connectors to Jk 
using ajp13, I'm having problems getting apache/Jk to talk to Tomcat.  
I believe I've been very careful with the port assignments and whatnot, 
but continue to get failure, and the following error in the mod_jk.log:

ajp_connection_tcp_get_message: Error - Wrong message format 0x4854

I'm running tomcat 4.1.18 with Apache 2.0.48 in a Solaris 8 environment.
Any help that can be offered is much appreciated.
Here are some config file snippets, for your pleasure:

workers.properties:
--
worker.list=worker1
worker.worker1.port=8009
worker.worker1.host=tomcat-dev1
worker.worker1.type=ajp13
worker.worker1.lbfactor=1

Restrict access to a webapps folder based on ip

[Joshua Russell]

I was wondering if it was possible to restrict access to a certain 
webapps folder based on the ip the packet was coming from. 

So if .../webapps/app1 was for an intranet site with all ip's within a 
certian range having access, and /webapps/app2 for a web-site allowing 
machines with any ip.

Does this make sense to anyone? And if so is there a better solution to 
hosting two applications on the same server...???Two instances of 
Tomcat...different ports??

I am currently running Tomcat 4.0.6 standalone...

Apache 2.0.47, Tomcat 4.1.27 with mod_jk2 2.0.2 AND mod_deflate

[Joshua McCulloch]

I have setup Apache 2.0.47 on Windows XP to serve
jsp/servlet requests
using Tomcat 4.1.27. I did this using the mod_jk2
module and was able
to successfully connect to http://host/examples and
get the tomcat
example pages. I'm using JDK 1.3.1-03.

I then configured mod_deflate and was able to verify
it works by
telneting to port 80 and giving it a request using
"Accept-Encoding:
gzip, deflate". I did this on both the main index.html
file and the
main manual document.

However, any request to /examples/* (served by jk2)
does NOT get
compressed. I even placed the main index.html file in
TOMCAT_HOME\webapps\examples\ and that too will be
send un-compressed!

I've tried a variety of options within the 
section, and
switching the order of the LoadModule statements.

Is what I’m trying to do possible? Should I switch to
mod_jk or mod_webapp, or maybe downgrade to Apache
1.3.x?

Below are the configuration files/sections which
should be relevant:

Workers2.properties
[common]
debug=10
[config]
debug=10
debugEnv=10
[shm]
file=c:/apache/apache2/logs/shm.file
size=1048576
[channel.socket:localhost:8009]
info=Ajp13 forwarding over socket
tomcatId=localhost:8009
[uri:/examples/*]
info=Map the whole webapp

httpd.conf:
LoadModule jk2_module modules/mod_jk2-2.0.43.so
LoadModule deflate_module modules/mod_deflate.so


SetOutputFilter DEFLATE

Options FollowSymLinks
AllowOverride None


Thanks,
Josh

Random, either Error 500: "The system cannot find the file specif ied " or images missing - Win2k : Tomcat 4.1.24 : IIS 5 : JDK 1.41

[White, Joshua A (HTSC, CASD)]

Environment:
Win 2k Server   
IIS 5.0 -> proxy using isapi_redirector2.dll -> Tomcat 4.1.24
JDK 1.4.1

Note: This is an internal application and is not accessed through a
proxy server or firewall.  The uri I have specified in the
workers2.properties file is [uri:/myapp/*]  



The Problem:

Five percent of the time, users experience missing pages,images, css or js
files.  When the page is not displayed, users see a "Page cannot be
displayed" IE error.  (With friendly error messages turned off, the actual
error seems to be "The system cannot find the file specified")

Looking through the log files, I see that the dll is returning a 500 error
to the user.  When looking through the tomcat logs, I see no such thing.
Could this be an ISAPI plugin problem?  Any suggestions on where to begin
debugging this problem?

If the users go directly to tomcat (running on port 8080) these problems
disappear.  There are some known problems with IIS and isapi pluggins, but I
cant tell if this is related.  Anyone else experience Any help would be
appreciated.

Joshua

The system cannot find the file specified - HELP

[White, Joshua A (HTSC, CASD)]

I am proxying Tomcat through IIS using the isapi_redirector2.dll.

The uri I have specified in the workers2.properties file is

[uri:/myapp/*]

Ninety five percent of the time, every thing works fine.  The other five
percent of the time, users experience missing images and or css or js files.
Other times a 500 error is returned to the user (Page cannot be displayed).
When "Friendly error messages" in IE is turned off, I see the message "The
system cannot find the file specified".

Looking through the log files, I see that the dll is returning a 500 error
to the user.  When looking through the tomcat logs, I see no such thing.
Could this be an ISAPI plugin problem?

Tim,

The getHeader methods does not return any reference to any kind of header

I would have to create my own setHeader method instead.  There has to be an
easier way to do this.

Any other ideas?

You can do this via a Filter and HttpServletRequestWrapper, where your 
imlpementation of HttpServletRequestWrapper will extend the needed getHeader

methods to send the additional stuff you need.

Hey all,

My production application uses a site minder web agent.  This agent places
two name/value pairs into the request header, one for userName, the other
for domain.

In my application, I have a filter which looks for these values to make sure
the user is logged in.  Currently I do not have site minder in my
development environment, but I would like to simulate its functionality by
placing values in the request header before my other filter looks for them.

I know that you can place values in the response header.  Can it be done
with the request as well?

  Hi again,

  Just replaced my workers2.properties file with yours (and changing the
path
  to the shm file according to my Tomcat 4 installation): exactly the same
  problem...

  Besides, I double-checked the W2K Event log entries and couldn't find that
  entry (or similar) you mentioned :
  "Error: [jk_shm.c (333)]: shm.init(): No file"

  I really don't know what to do. Why is this such a pain to simply connect
  IIS and Tomcat, even when following the instructions ?

  Thanks again for your help...

  Aha!  I thought so :-)

  Here's my workers2.properties file: -

  <
  #
  # workers2.properties
  #
  [shm]
  file=C:\tomcat4\logs\shm.file
  size=1048576

  [channel.socket:127.0.0.1:8009]
  info=Ajp13 forwarding over socket
  tomcatId=localhost:8009

  # Map the Tomcat examples webapp to the Web server uri space
  [uri:/examples/*] info=Map the whole webapp
  -->

  The [shm] entry seems to be some sort of shared memory area and I've seen
  references to something called the 'scoreboard' in conjunction with it.
  Anyway, the bottom line is you need this entry for JK2 to work on IIS.  If
  you look in your W2k Event log you'll probably also notice a tell-tale
  Tomcat application error similar to this: -

Error: [jk_shm.c (333)]: shm.init(): No file

  Hope this helps.

context.xml question

[White, Joshua A (HTSC, CASD)]

Three questions here:


Can the docBase attribute of the context element be relative?  The location
of the docBase will be different depending on where I am deploying to.
Given mywebapp/META-INF/context.xml, the document root will always be two
directories up from the context.xml file.  Could this be done?  Is there a
better way of managing this?

On a seperate note, when installing a war file using the catalina ant task,
should tomcat automatically look in the META-INF directory of the war file
for a context.xml file?  I have not been able to get this to work.  I wound
up specifing both the config file as well as the war file in the install
task.  Is this how it is supposed to work?

If your set the reloadable attribute of the context element to true, do you
still need to use the ant reload task to pick up your changes? 

Regards,

Joshua

Best practice development directory layout for deploying exploded war

[White, Joshua A (HTSC, CASD)]

Hello all,

My company is contemplating the idea of deploying servlet applications on
Tomcat in production. (woohoo!)

I am hoping that some of you may suggest some best practices for laying out
your development directory structure.  I have my directory structure layed
out like an expanded war file.  If I point tomcat to this directory for
expanded deployment, it makes it easy to edit/source control jsp files.  It
also makes copying/updating/deleting jar/lib files a pain.  Do people set up
a empty classes directory under the web-inf to source control their
properties files or is it better to put them in a separate directory and
copy them there?

Is the best practice to do it this way or to copy your jsp/classes/libs to
another exploded directory all together?

Best Regards,

Joshua

loadbalancer:

Uncomment the top line and remove the rest.

RE: Problem with sticky session in Tomcat4.1.18 and Apache 2.0.43 using mod_JK Connector.

[Joshua Sunil Kumar]

Hi
I check out in the server.xml there is no entry for jvmRoute. There is
something called jmvRoute is it a typo or something cos I corrected it to
jvmRoute and it still does not work



This is tag directly taken from server.xml in the tomcat4.1.18's conf
directory

Filip's memory is correct.

In server.xml you need an entry on the engine element:

BlankI remember there being a property called jvmRoute in the server.xml
file that would allow the Apache workers to make sure you got the right
Tomcat server upon the next request.

otherwise, you can just cluster enable your system, and it should work for
you.

  Hi

RE: Tomcat class loader problems?

[White, Joshua A (CASD, IT)]

Hmm,

If I drop the war into the webapps directory all is fine as well.  The
problem only seems to happen after using the custom Tomcat install/deploy
tasks.  Anyone have similar problems?  After deploying using the
install/deploy ant tasks, the application runs fine with the exception of
this one class file.

Problem rendering Greek and Latin Characters in Tomcat 4.1.18

[Joshua Sunil Kumar]

Hi 

The JSP page that 
I am using has Greek and Latin Characters. I am unable to display it properly in 
the browser. 
I am fetching data 
from the a Oracle Database which is stored in UTF-8 . When I display it on the 
browser this the characters are getting garbled. Ex- Grønbæk 
If I change the 
View-->Encoding--> to UTF-8 then I am able to view it properly  as 
Ex- Grønbæk 
 
1.I am setting the 
the following META tag
But still 
when I check it up in the browser the encoding setting is 
ISO-8859-1
 
2. I have tried 
setting the response.setContentType("text/html;charset=UTF-8"); This also does 
not work. 
3. I have tried 
putting  <%@ page contentType = "text/html;charset=UTF-8" %>. This 
also does not work.
 
4. I have changed 
the setting Tomcat4.1.18 for web.xml file to 
 
Set Character 
Encoding    
filters.SetCharacterEncodingFilter    
    
encoding    
UTF-8    
    
 
 
5. I thought 
there might be a problem with the Apache webserver and then I set this in the 
httpd.conf file
AddDefaultCharset UTF-8 (default is 
ISO-8859-1)
Having done 
all the setting still I am unable to the view the characters properly. 

 
I am running 
Tomcat4.1.18 with Apache2.0.34 using the JK2 Connector on Solaris 
5.8.
 
Code snippet 
which I have used.
 
<%@ page import="java.util.*" %><%@ page 
import="java.io.*" %><%@ page import="java.sql.*" 
%><%
 
    
Class.forName(driverClassName);

password);    
con.setAutoCommit(false);    
Statement 
stmt=null;    
ResultSet 
rst=null;    
stmt = 
con.createStatement();    
String testString=null;
 
    
try {
 
 
 
    
rst = stmt.executeQuery(queryString);    
}    
catch(SQLException e)   
{    
System.out.println("error while fetching data from old 
table.");    
System.out.println("Error message:

return;    
}
 
    
while(rst.next())    
{    
testString = rst.getString(1);
 
    
out.println("LastNAME "+ testString);
 
 
}
 
%/>


 
7. I have also 
tried using the String.getBytes("UTF-8); But this also does not 
work.
 
I would like to know if any other setting also needs to be 
made for in addtion to what I have done so that it 
works.

Configuring JNDI LDAP Datasource - NOT USED FOR AUTHENTICATION

[White, Joshua A (CASD, IT)]

How can I declare an LDAP datasource in the server.xml file without the need
to use it for authentication.  The documentation I have read so far assumes
that I am using LDAP for authentication.  When looking at the datasources
section of the JNDI docs, it assumes a relational database.  Can someone
give me an example?

RE: Web app configuration problems

[White, Joshua A (CASD, IT)]

Ok,

Before I deploy the application using ant (using the manager utility), I
first attempt to undeploy the application.  I think that the undeploy
command removes the context defined from the server.xml file from memory.
Here is what I did.

1. Start tomcat, app works fine (uses context from server.xml)
2. Use ant to first undeploy the application, then install the application
using the same context path
3. The applications resources are unavailable
4. Restart tomcat
5. App works fine

If I restart tomcat, the app works fine.  If this is true, how do I keep
re-deploying an application in development without removing the entries that
were defined in the server.xml file from memory?

Web app configuration problems

[White, Joshua A (CASD, IT)]

I am hoping someone could explain how Tomcat uses context paths.

In my server.xml file, I have declared a seperate context and some JNDI
resources for /myapp-web.

The way I deploy my web application determines if these resources will be
available or not.  If I drop my web applications war file (myapp-web.war)
into %CATALINA_HOME%/webapps, I am golden (The war does not even unpack).
However, if I use the manager utility from ant, the resources are not
available.  

I have checked to make sure that ant installs the application correctly.  I
receive the following message from ant:

[echo] OK - Installed application at context path /myapp-web

This utility seems to place an unpacked version of the war file into the
%CATALINA_HOME%\work\Standalone\localhost directory.  This does not seem to
be enough.  If I manually drop the war into the webapps directory,
everything works again.

If I deploy using only the manager utility, how should I configure its JNDI
resources so they work?

RE: JNDI datasource frustrations...

[White, Joshua A (CASD, IT)]

It looks like this is a common problem.  I have found several posts on
several boards about this problem.  Unfortunately, no solution.  

Does it matter whether I declare the resource in the server.xml under the
global naming resources or do I need to define one specific to my
applications path?

Has anyone successfully connected with MSSQL Server 2k?

All,

It seems that I may be having a problem instantiating the Sql server jdbc
driver.  I have copied the following jars into my $CATALINA_HOME/common/lib
directory:
msbase.jar
mssqlserver.jar
msutil.jar


I have the following in my server.xml file:






username
someuser


password
password


driverClassName
com.microsoft.jdbc.sqlserver.SQLServerDriver


url
jdbc:microsoft:sqlserver://localhost:1433


maxActive
100


maxIdle
1


maxWait
1




In the Tomcat console, I see the following:

java.sql.SqlException: Cannot load JDBC driver class 'null'

What am I doing wrong here?

If you're using 4.1.12, make sure the invoker servlet mapping the

passing a session from non-SSL to SSL

[Joshua Szmajda]

Hi all,

 Not sure if I actually sent this the first time or not, so it's 
going out again.. sorry if it's a duplicate :)

 I'm upgrading an application from Tomcat 3.2 to Tomcat 4.0, and I'm
noticing that my application is now losing track of its sessions when I
switch from non-SSL to SSL. The code worked fine in Tomcat 3.2.. I was
wondering if there's something I'm missing. My server.xml has a single
Ajp13 connector and a plain vanilla host / context configuration. I've
JKMount'ed /* to ajp13 in apache on both the normal and SSL virtual hosts.

 I'm sure it's something in the spec that's changed, but I can't for
the life of me find out what. Changing the code is possible, but
preferably avoidable as I didn't write it.

Thanks in advance!

wrapper.classpath=@JSERV_CLASSES@

Normally I would call to a separate class directory but I am just trying 
to get it to work at this point.
I also added the following to my tomcat3.conf although it is my 
understanding that tomcat3 doesn't
care about shell variables for the classpath:

CLASSPATH=/home/vhosting/sfl/htdocs/classes:/home/vhostings/sfl/htdocs/classes
export CLASSPATH

Help would be greatly appreciated,

Thanks, I went ahead and told the developers that they were just going to

(backwards compatibility issue with the code). Thanks again.

Re: Re[2]: Tomcat redirect

[joshua wentworth]

Yeah, I figured that out a bit later. The problem seems to be that Tomcat is
just ignoring the call to /servlet/Whatever.
The situation is like this, I'm trying to get as specific as possible now.
The code looks like this:
 

And if someone clicks on that button they get a 404 and Tomcat returns the
error that it can't find /servlet/CatalogServlet. This exists without any
 stuff setup in server.xml.  The problem is that in the original
call to the original servlet we have apache redirecting the request to
http://our.server.com:8080/spike/servlet/OurServlet and when OurServlet
calls OtherServlet via the code above it tries to locate it on
http://our.server.com:8080/servlet/OtherServlet and that doesn't work. It
has to have the /spike/ in there. So... Any idea how I can do that? One of
the issues is that I can't change the code in the servlet itself (Otherwise
fixing this would be trivial).

Re: Tomcat redirect

[joshua wentworth]

I was hoping of something within the Tomcat configuration itself since we
don't use an index.jsp file. To be more specific about my problem, Whenever
a servlet calls another servlet in Tomcat it isn't intercepting the
/servlet/ directive and replacing it with /spike/servlet/ which is what it
should be doing. Perhaps I'm overlooking something obvious in the
configuration that will do this, but I've tried putting a




Entry in the server.xml file, but that didn't seem to do it either...

You can use the following in my index.jsp, so that the main page will be
redirected to some other location: <%
response.sendRedirect(response.encodeRedirectURL(""));
%>

Tomcat redirect

[joshua wentworth]

I am trying to have Tomcat redirect certain requests to other applications
or other sites. But I can't find anything in the documentation or in any of
the messageboards about any kind of forward or redirect function in Tomcat.
Is there such a function, and if so where can I find documentation on it?

I'm sure it's a rehashed issue, but I'll try anyway. (Apache 2.0.35 & tomcat 4.0.3) & mod_webapp.so

[Joshua Chen]

Hi all,

I've been trying to get my Apache 2.0.35 & Tomcat 4.0.3 up and running (on
solaris 2.7).  Apache works great, and tomcat works great as well.  But now
I try to use the mod_webapp.so file that came with apache 2.0.35, and I get
the

undefined symbol: ap_pstrdup

So I read in a couple of archives to just try and compile the mod_webapp
from the source, since ap_pstrdup is now apr_pstrdup.  no problem, I go get
the jakarta-tomcat-connectors-4.0.4-b2-src.tar.gz and go ahead and start
compiling.

I get to the end, and everything is successful.  No errors, no compilations
issues.  What I don't get is a mod_webapp.so.   (file listing at the end)

I look at my Makefile in the apache-2.0, and the only target it has is the
mod_webapp.la.  Now I'm lost.  I don't think I can do a LoadModule
webapp_module libexec/mod_webapp.la, so I'm trying to figure out what I have
done wrong.  (I tried this about a week ago, and get errors in apachectl
configtest)  I have this funny feeling I'm just missing a stupid little
detail, but I can't for the life of me figure it out.

The libtool is version 1.4.2
gcc is 2.95.2

Any ideas on how to get a mod_webapp.so?  Any help is appreciated.  (file
listing and Makefile below)

Thanks in advance
Joshua Chen

Jars in WEB-INF/lib and RMI stubs in WEB-INF/classes not found

[Joshua van Tonder]

How does classloading work in tomcat 3.2.2?

In deploying my application I am having problems getting classes loaded
aren't on the system classpath. I changed the tomcat.bat so that the
generated classpath doesn't doesn't include the system classpath and only
includes things built by the batch file.

I have placed log4j.jar and crimson.jar into WEB-INF/lib for my app.

For other reasons crimson.jar needs to be 1st on the classpath (specifically
b4 parser.jar) and I so try adding it by doing like so in batch file:

set CP=%TOMCAT_HOME%\webapps\MYAPP\WEB-INF\lib\crimson.jar;%CP%

But it isn't found. If I instead do: CP=%TOMCAT_HOME%\lib\crimson.jar it
also isn't found.

Only if I place it outside of %TOMCAT_HOME% and reference it are classes
found.

The wierd thing is that I can place log4j.jar in the %TOMCAT_HOME% and have
things work (but also can't find classes from it if it's added to classpath
referenced from WEB-INF/lib).

This also extends to rmi stubs in the WEB-INF/classes directory. Other
classes from our app in this dir our found except for the stubs.

any ideas, I'm stu[bb|mp]ed...

RE: Loosing Connections in a pool

Subject: Loosing Connections in a pool


Hi,

My tomcat application runs in a production environment for about 24 hours
before it fails and must be restarted.  During that time JDBC connections to
Oracle become ignored and eventually disappear.  A fair guess is that I am
loosing memory, threads and  resources in general until there is nothing
left and only a restart cures the matter.

Unfortunately, tomcat, rather than apache is serving much of the pages and
graphics.  That may be a contributing factor?

I am using:

Solaris 8
Oracle 8.1.7
tomcat 3.2.1
apache 1.3.19
and Java 1.3

Does anyone have an idea of what sort of problems I might be having?  Any
known resource leaks or threading issues?

Thanks!!

Dan

RE: multiple instances of tomcat

[Joshua Sharp]

To seperate the JSP repositories for each instance, you can specify the jsp
compiled classfile directory in the ContextManager tag in Server.xml. Just
change the workDir variable to different directories. That way you don't
have to orry about reading the wrong JSP repository.

Hi,

I am not sure if it possible to run two instances of tomcat in standalone
mode with different versions of server.xml. Tomcat has this strong notion of
home built in to, the two tomcats should have different homes if they were
to work mutually exclusive of each other. For if the two instances were to
use the same home they both of them would see the same set of
webapplications, use common logs, work directory and other configuration
file in the conf directory.

Thanx

It is possible: You must have two different server.xml files. In the
server.xml file you can configure that port in the http connector
element. You also need to have 2 startup-scripts that call tomcat with
the appropriate server.xml file. You don't need Apache to do this.

Peter.

Virtual Hosts w/ Tomcat+Apache

[Joshua Lifton]

The "Tomcat-Apache HOWTO" document that comes with the Tomcat 3.2.1 distro
mentions that there are two different ways to configure Tomcat for virtual
hosts; one is to use a different Tomcat for each Apache virtual host and
the other is to use the same Tomcat for each Apache virtual host.  In the
case of the latter, the HOWTO file mentions that Apache's httpd.conf file
must be configured using the  directive and gives an example
of such.  In addition, the HOWTO file states that Tomcat's server.xml must
be configured using the  directive.  An example is given for this as
well, but it is identical to the example given for the 
directive in the httpd.conf file.  Is this a typo?  I checked the
server.xml file and found a rough sketch of the  directive being
used for working with virtual hosts, but would like to see a more complete
example.  Anybody have experience with this?  If it is a typo, how
do we go about fixing it?  Thanks, josh

tomcat contexts and JVMs

[joshua . eapen]

Hi All:

I am a bit confused.  Does each context in server.xml have its own JVM
session?

For example, I have two contexts:
1) Catalog - for a product catalog app
2) Support - for customer support apps

Both these contexts need a connection pool to my backend Oracle database.
If both contexts use separate JVM sessions then I would have double the
number of connections to my Oracle database and the connections would
increase per context added.

Is there a way to share the connection pool object across contexts?  Again
all this relates back to whether the various contexts runs within one JVM
session or each has its own JVM session.

Thanks,

Joshua
