jar_cache

[Ken Anderson]

Does tomcat ever clean up these jar_cache files in the work directory?
There's over 900 of them in there.
Thanks,

ibm jdk 1.3 or sun jdk 1.4 ?

[Ken Anderson]

Which is faster for a tomcat webapp?
IBM JDK 1.3 or SUN JDK 1.4?
Any reported problems with 1.4 & Tomcat?
Any decent benchmarking tools I can download and test with myself?

optimizing tomcat for use with apache only

[Ken Anderson]

This is a barebones server.xml for using mod_webapp with apache only (no 
  standalone tomcat service)
I'm using tomcat 4.04b2, a fresh mod_webapp.so, apache 1.3.22, on redhat 
7.2. Everything works nicely, and it's fast, but I'd like to squeeze as 
much performance as possible out of the configuration as possible. Any 
ideas for optimization?

Cannot shutdown "conn" error in apache logs

[Ken Anderson]

Tomcat works fine, but this shows up in apache error log.
Any ideas?

[Tue Apr  9 10:53:13 2002] [error] Cannot shutdown "conn"
[Tue Apr  9 10:53:15 2002] [error] Cannot shutdown "conn"
[Tue Apr  9 10:53:18 2002] [error] Cannot shutdown "conn"

Seems to result after every request

"conn" is the name of the webapp connection in httpd.conf

 WebAppConnection conn warp localhost:8008

Thanks,

Ahh.. found the issue. Seems that unless I restart apache after 
restarting tomcat this error exists, otherwise it doesn't.
This didn't happen with previous mod_webapp.

Re: Starting Tomcat 4 as an NT service

[Ken Anderson]

On WinXP, I found I had to do
%CATALINA_HOME%\bin\tomcat.exe -uninstall "Apache Tomcat"
To uninstall the Tomcat Service.

%CATALINA_HOME%\bin\tomcat.exe -uninstall Apache-Catalina
gave me a cryptic error about "overlapped i/o in progress" and didn't 
remove the service.

You might try hitting the good(jrun) url and bad(apache) url with lynx

Re: Please help me on a question about TOMCAT OR APACHE + TOMCAT

[Ken Anderson]

Tomcat Standalone is not an enterprise webserver, and will not stand up 
to the pounding that Apache can take. I think you would find that your 
response time drops off rather quickly if you are hosting 200 active 
virtual domains. If you don't serve many concurrent requests, and don't 
need the power and flexibility of apache, tomcat standalone is fine.

Re: RES: How can I automatically start a servlet in a specific time?

[Ken Anderson]

This sounds like it could be a simple java app?
Are you sure this needs to be a servlet? If so, I suppose the easiest is 
just to write a controller servlet for it that only executes the method 
when the time is right, and sleeps the rest of the time..
Someone else suggested some code for this.

Re: Tomcat:Port 8080 or 8007?

[Ken Anderson]

If you have all the examples installed, and tomcat is starting okay, you 
should see content at http://localhost:8080
The apj12 connector (and port 8007) is for apache; you can ignore it, 
unless you are running tomcat with apache
You need full jsdk to run jsp, not just jre.

As a workaround, you can use an apache alias directive.
 Alias /images/ "$tomcat_home/webapps/webapp_name/images/"

Re: Apache serving static content

[Ken Anderson]

Works fine for me, and since the uri changes to /images/test.gif or 
whatever, mod_webapp ignores it, and the files can still live in the 
webapp directory, which is what you want right?
Maybe I misunderstood the problem?

Re: Tomcat 4.0.x and OpenSSL

[Ken Anderson]

If Apache is an option, I'd use it, since current builds (for many 
distros of linux) come with mod_ssl & openssl built in. All you have to 
do is install Tomcat, configure the apache connector 'mod_webapp' (there 
are good links on the list for how to do that), then Apache will handle 
all SSL requests for you, including your /servlet requests. This is a 
much better solution, since openssl/mod_ssl is much faster than java ssl 
in tomcat standalone, and also much easier to configure, plus you get 
all the advantages of Apache's wide variety of configuration options.

Re: Questions about Tomcat and Apache Integration?

[Ken Anderson]

Seems to be a common problem.

The webapp Deploy statement (using mod webapp) will run everything in 
the 'deployed' directory tree, including images through tomcat. It's not 
a good idea to put static resources there, IMHO. If you have to put them 
there, but want apache to serve them, then us the Alias directive in 
Apache so that apache grabs them from a different URI, like this:
alias /images/ /$tomcat/webapps/webapp/images/
This way the uri doesn't contain the path that is in the webapp Deploy 
statement, so it wont pass the request to tomcat.

Re: mod_webapp + httpd.conf

Or, specify a virtualhost and deploy the connector within that virtualhost.

-
NameVirtualHost 
192.168.1.1


ServerName www.blah.com
DocumentRoot /blah
WebAppConnection conn  warp  localhost:8008
WebAppDeploy examplesconn  /examples
[other statements go in here too.]

-

This has the advantage of allowing you to deploy more virtual hosts with 
different webapps easily. Example:


ServerName ADMIN.blah.com
DocumentRoot /admin
WebAppConnection conn2  warp  localhost:8008
WebAppDeploy adminconn2  /admin
[other statements go in here too.]

It isn't so. There is no problem serving static content through apache 
using mod webapp to server only servlets, jsp. The setup is different

Re: Which Apache-To-Tomcat Connector

[Ken Anderson]

I just did some similar benchmarking, though I didn't test with tomcat 
standalone, since I need Apache, and don't have standalone configured. 
I'm sure there are other factors, O/S, JDK, etc, but here's what I 
found, using mod_webapp, with Tomcat 4.04b2 on Sun JDK1.4 and Apache 
1.3.22 on RedHat 7.2.

Doing ./ab -n 1000 -c 100
Getting 15267 byte web page file; text and images (same file contents) 
in all three cases.

Apache only static content
- 52 req/sec avg. (no errors)

Apache through mod_webapp - getting same file - static content.
- 50 req/sec avg. (no errors)

Apache through mod_webapp - getting servlet/velocity generated page, 
based on sql result from mysql (simple select query through mm.mysql 
jdbc driver, using dbConnectionBroker pooling)
- 37 req/sec avg. (no errors)

I did notice that mod_webapp was a bit unstable; delivering some widely 
varying performance, and hanging 1 out of 20 tests I ran, though I have 
never seen this problem under normal loads. Also, since I didn't test 
standalone performance, I am not sure the problem I had was really with 
mod_webapp.

I tried hitting an WinXP dev box that runs TC standalone, but it 
couldn't handle the ./ab -n 1000 -c 100 load. It returned 'broken pipe' 
for anything over -c 5.

Re: tomcat/apache with ALIASES (Was canonical names)

h... have you tried Apache's ServerAlias Directive? I know this 
works with static content, but I'm not sure if mod_webapp respects it or 
not..

Re: tomcat/apache with ALIASES (Was canonical names)

[Ken Anderson]

This works on Apache 1.3.22 on RedHat Linux, using mod_webapp with 
tomcat 4.04b2. mod_webapp built from 
'jakarta-tomcat-connectors-4.0.4-b2-src'

Here are the relevant sections of httpd.conf:

-
LoadModule webapp_module modules/mod_webapp.so
AddModule mod_webapp.c

UseCanonicalName On

NameVirtualHost 192.168.1.10


 DocumentRoot /home/user/public_html
 ServerName www.domain.com
 ServerAlias test.domain.com
 WebAppConnection conn warp localhost:8008
 WebAppDeploy mywebapp conn /go

Running on R.H. linux 7.2 with jdk 1.4 and Tomcat 4.0.4-b2. No

Troubles with the list: 

apache/mod webapp - Premature packet header end

[Ken Anderson]

Using mod-webapp/apache, I'm seeing a lot of this in the logs, though 
the site works fine:


2002-12-12 05:35:23 [org.apache.catalina.connector.warp.WarpConnection] 
Exception on socket java.io.IOException: Premature packet header end
at 
org.apache.catalina.connector.warp.WarpConnection.recv(WarpConnection.java:237)
at 
org.apache.catalina.connector.warp.WarpRequestHandler.handle(WarpRequestHandler.java:112)
at 
org.apache.catalina.connector.warp.WarpConnection.run(WarpConnection.java:194)
at java.lang.Thread.run(Thread.java:536)


I've found several references to the "Premature packet header end" error 
messages in the archives, but no clear answer except a suggestion that 
these errors can be ignored, and are caused when the apache process 
terminates (due to MaxRequestsPerChild ??). Are there any other thoughts 
on this? Any way to fix? Do newer versions of mod_webapp detect this 
more gracefully?

Thanks,
Ken Anderson

Re: Simultaneous request from same IP

[Ken Anderson]

You just need a new traffic cop object created at the beginning of doGet();

TrafficCop tc = new TrafficCop();

That way you are not talking to the same tc object when you say tc.add();

TrafficCop is thread safe because add() is

No, this is false. 

The add() method is syncronized, and therefore thread safe. But that is
not where the problem lies. 

TrafficCop may be thread safe, but access to it is not.

Two objects are updating a single object - the last one to do it wins.

Re: Naïve question about root

I know this is a naïve question, and slightly irrelevant to the newsgroup...

I keep getting told left and right not to work as root.  I heeded this
advice a while back and created a user.  Here is the thing.  My RH 7.3 box,
running Apache 1.3.27 & Tomcat 3.1.17 (no I haven't gotten them connected
with mod_jk yet:) ) is logged in as root.  But I work on my files through a
secure shell from my workstation, where I log in as the user I created.  Is
it not safe to leave my box logged in as root?


Do you trust the people who have access to your computer? Logging in as 
root over the network isn't recommended, since telnet logins are still 
pretty common, and sniffers can grab plain text passwords from the wire.

Running tomcat or apache as root isn't a good idea, since a minor 
security hole (we've seen dozens of them lately) can be a major problem 
if the user is root.

My concern is when people access my website can they somehow get into my box
and wreak havoc?  For example with my current setup people are accessing a
website hosted on a machine that is logged in with root access   Is it
better that I sign in on the actual box as this created user only changing
login to root as needed or does the logon of the actual box not matter as
long as I am not messing around as root...?  If I should sign onto the box
as this user, how can I make sure this user has rights to Apache and Tomcat?





(as of right now this user has rights to execute java commands, but I am not
sure if there is anything special I need to do for apache and tomcat).  On a
side note is there anyway to create a user that has "almost" root access but
can't do the damage root can do?


Check out sudo, it's probably available on your machine, and allows non 
root users to do some things (you define) as root.

Again naïve, but thought I would throw it out here anyway :) Thanks!!

Re: Tomcat SSL Setup

[Ken Anderson]

Have you considered the advantages of using one of the apache connectors 
instead of tomcat standalone for SSL support?

I fought with Tomcat ssl support a couple years ago, and was unable to 
get it to work. I'm sure the support is there now, but ssl support is 
transparent if you use mod_jk or mod_webapp with Apache, and it's 
easier, since you already have all the cerificates in place.

The downside is that the connection between apache and tomcat is NOT 
encrypted, so if you are running TC and Apache on different servers, 
this might be an issue.

Subject: Tomcat SSL Setup


Hello all,
I've been working on getting SSL configured for Tomcat and seem to be
having a small problem.  I must be mistyping something because the only
thing I get back from Netscape 7.0 is:
	"Netscape 7.0 and www.mydomain.com cannot communicate securely
because they have no common encryption algorithms."

Here is what I have done so far:

1.	I changed /etc/tomcat4/server.xml and uncommented the following:


className="org.apache.catalina.connector.http.HttpConnector"
   port="8443" minProcessors="5" maxProcessors="75"
   enableLookups="true"
   acceptCount="10" debug="0" scheme="https" secure="true">
  
className="org.apache.catalina.net.SSLServerSocketFactory"
   clientAuth="false"
keystoreFile="keystores/mydomain.keystore" keystorePass=""
protocol="TLS"/>


2.	I ran the following commands to import the Verisign key:
	/usr/java/j2sdk1.4.0_01/bin/keytool -import -alias root \
	  -keystore /var/tomcat4/keystores/mydomain.keystore  \
	  -trustcacerts -file /etc/verisign.key

3.	I ran the following commands to import a previously created SSL
certificate
	/usr/java/j2sdk1.4.0_01/bin/keytool -import -alias tomcat \
	  -keystore /var/tomcat4/keystores/mydomain.keystore  \
	  -trustcacerts -file /home/httpd/ssl/www.mydomain.com.cer

4.	In /etc/tomcat4/server.xml, I noticed the following:
 * Download and install JSSE 1.0.2 or later, and put the JAR
files
   into "$JAVA_HOME/jre/lib/ext".
 
	I found jsse.jar in $JAVA_HOME/jre/lib so I ran the following:
		ln -s $JAVA_HOME/jre/lib/jsse.jar
$JAVA_HOME/jre/lib/ext/jsse.jar

5.	I then restarted Tomcat and tried the following URL:
	http://www.mydomain.com:8080/examples/servlets/index.hml

	This was a test simply to make sure Tomcat started properly.  In
this it worked fine.

6.	I then restarted Tomcat and tried the following URL:
	https://www.mydomain.com:8443/examples/servlets/index.html

	This test failed with the above error message.


Does anyone have any ideas?  Oh, and BTW, I can visit
https://www.mydomain.com/index.html and the home page for the site comes
up in SSL mode without a problem, so I know that the SSL certificate,
under Apache, is working fine.

Thanks,
Justin L. Spies

Ken,
Thanks for the hints.  Since they (Apache/Tomcat) are running on the
same system at this point, that won't be an issue.  Could you point me
the direction of some documentation that would help me get this setup?
I've setup mod_jk with standard Apache before and it has been straight
forward.  I am assuming that Apache handles the encryption/decryption
and passes the requests off to Tomcat via the connector AFTER it
decrypts the request--is this correct?


That is correct.

I have only set up ssl with mod_webapp, and it's just a matter of adding 
duplicate WebAppDeploy statements to the ssl  section in httpd.conf

I'd assume it's the same with mod_jk, since the autogenerated 
mod_jk.conf contains the non-ssl virtualhost section, you'd just need to 
mirror that with an ssl virtualhost section in the file by adding a 
duplicate  Section to server.xml for the ssl 
virtualhost. There may be gotchas to this that I'm not aware of with jk, 
since I have not used it with apache & ssl before.

You'd also probably want to disable the coyote connector on port 8080 in 
server.xml too.

Re: SSL setup Apache -> Tomcat

[Ken Anderson]

I'm assuming that you are using mod_ssl with Apache, and not running a 
separate SSL webserver like Stronghold, right???

I've not setup ApacheSSL/Tomcat before except with mod_webapp, but I 
have setup Apache/Tomcat with mod_jk as well (just not with ssl support).

Here's my 2 cents anyway:

The JkMount statements can go inside or outside a VirtualHost Block.

Outside - they will apply to all virtualhosts
Inside - they will apply to just that virtualhost
(mod_webapp and most other apache mods work this way)

So, if you have something like this:
JkMount /examples/*.jsp  ajp13

You should be able to place that inside your SSL VirtualHosts too.


SSL.
JkMount /examples/*.jsp  ajp13

find something telling me how to formulate such a JkMount statement, but
can't seem to find anything.  Any suggestions?

I would imagine you do not need to switch to warp and the majority of the
list would say not to use warp.  I only use it due to the fact it is not
currently convenient for me to upgrade the perl on my HP-UX box to 5.05.

The only thing I had to do was to place the warp equivalent of JKMount in
the virtual host for the 443 port and I was off and running.  Do you place
the JKMount directive in each virtual host or do place them outside of all
virtual hosts so that the directive apply to all hosts?  I do know for JRUN
2.3.3, the placement of the mapping directive relative to the virtual hosts
makes a diference of operation.

We have a number of Apache/Tomcat webapps that run through SSL with the
certificate only on the apache side.  However we are using the warp
connector and if you are using mod_jk you may have a different behavior.

Ok, I  have been reading through the archives of this list and this is not
good

I have one registered domain for which I purchased a certificate for. Apache
is set up to use this certificate, and I can access my Apache app through
https://.  Now I added some JSP to my site, and I need this JSP to be secure
as well.  I've seen this mentioned a number of times, and as you guess when
I try to access https://mydomain.com/mywebapps the server infinitely hangs.
I just finished reading how SSL from Apache to Tomcat is not implemented...
Is this true?  Is the scenario I want not possible?

Can I set up my certificate separately in the Tomcat config files? Will this
work?  The Apache app processes a server side transaction and on the last
page the connection to my backend system is ended as the last page is
loaded.  This last page has a link that when clicked, only sends 2
non-critical variables to my JSP.  But as I mentioned I need this JSP to be
secure.  ... so even if the SSL connection is broken, then renewed on the
Tomcat side, that would be sufficient (both are under same domain name, and
on same physical box)... Any suggestions?

Thanks!

Btw...where is everyone today? Does the whole world besides me get off early
on Friday's?? ; )

Re: [ot?] Frontpage extensions for tomcat or related items

[Ken Anderson]

FP extensions are an MS centric server based technology primarily for MS 
based Webservers (although there are limited versions for unix/linux 
with gaping security holes...). They support server based M$ widgets 
that your FP web pages can talk to and do things like counters and forms 
and chat with WYSIWYG drop-in 'web-bots' (components that talk to the FP 
extensions on the server).

FrontPage, the editor, will no doubt mangle java code beyond recognition 
as it does to all other non-M$ code. Not sure if it even supports any 
kind of plugins to recognize non-M$ code... I doubt it.

Turn away from the dark side...

I don't think anyone has put any effort into an open source replacement 
for FP. The Mozilla editor (composer) could probably be extended to 
support the MS way of doing publishing and templates.
Over the last few releases of the Mozilla project, the composer 
component has come a long way from it's NS 4.x days.
For jsp support in the current versions of FP, it might be better to use 
SSI to include your jsp tags and keep them all in text files that FP's 
editor will leave alone? In this way, you'd create your own jsp 
'web-bots'? maybe?
