Forget mod_rewrite.  You just have to use the AJP Connector that is supplied
with Tomcat to connect it to Apache and have apache work on port  80.

http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/ajp.html

Surf about a bit to find the correct version for you if you are not running
Tomcat 4.0.

If there is something preventing you from using this connector tell the list
about it and we'll see what we can do ;-)

Enjoy,

Andoni.

RE: [SOLVED] -Xincgc, -Xms600, -Xmx600

[Jason Efting]

I finally managed to get my issue sorted out. After installing Tomcat
on another machine to do some testing I noticed that it had the following
value in the registry:

JVM Library: C:\jdk1.3.1_03\jre\bin\hotspot\jvm.dll

After changing this value to the server\jvm.dll my Tomcat is performing
incremental garbage collection as expected had doesn't crash when reaching
it's -Xms600 limit. I was even able to lower -Xms600 to -Xms256 and everything
seem stable.

Thanks for all the suggestions.

Any comments?

Re: precompiled jsp's as a part of application war file

[Bill Barker]

You have a bunch of servlet-mappings in your web.xml file that map that maps
the jsp URL to the pre-compiled class.  Jspc will generate these for you.

One gotcha with doing this is that TC 4.x won't find welcome-files (e.g.
index.jsp) unless there is an actual file with that name.  The file can be
empty, but it has to exist.

I was after this a couple of months back.  I found the solution in a list and 
accomodated it for 
tomcat.  Nothing briliant, nor is it the only way..  But its quick, short and sweet.  
This past 
week I did this "type" of heartbeat mechanism, currently for an app on BEA 7.0

Criteria for the Tomcat heartbeat:

1. Tomcat request
a. No response no tomcat   -  Down
b. A Response tomcat is up
   > If the requested servlet is not available  then Tomcat throws a 404 
status code

With this in mind:

create a heartbeat servlet  that calls hbURLCon = (HttpURLConnection)   
url.openConnection(); at 
some time interval.

StatusCode  =hbURLCon.getResponseCode();
if (statusCode > 400 & statusCode < 500) {
   // report Tomcat up
}  

You can get more sophisticated if you like.

isapi_redirector.dll

[Gupta, Ashish (CORP, Consultant)]

Hello All,
   I was able to find all the correct version of isapi_redirector.dll and the document 
for configuring tomcat 3.2 with IIS. However, the document does not mention the 
details of how to configure tomcat and IIS to work with each other if both are on 
different machines/Servers. 

The registry setting modifications mentioned in the installation file, do they need to 
be made in the IIS server or in the Tomcat server.
 
Any help would be appreciated.
Thanks,

Howdy,
Note that the premise of your question is flawed without a precise
definition
of "starting up" and "shutting down."  Consider a tomcat instance with N
webapps, each of which with one ServletContextListener.  Tomcat on startup
will
send the contextInitialized event to each of these listeners.  Each listener
may do things that take a long time, and may or may not do them in the
background.  

In the above scenario, when is the "starting up" state over and the
"started"
state entered?  Is it when tomcat sends all N events, or when all N events
are
done processing?

Similar scenarios can easily be construed for shutting down, and they are
not
limited to listeners as filters and servlets can all do varying amounts of
processing on startup and shutdown.

All of this may not matter in your scenario, so you may not have to worry
about
it at all ;)  But they are important to keep in mind if you're trying to
come
up with some sort of general solution.

RE: precompiled jsp's as a part of application war file

[Euan Guttridge]

Tomcat documentation advises pre-compilation is used only to test all your
jsps compile ok. Not to deploy pre-compiled jsps but instead to use
something like httpunit, or a webload script to automatically call your jsps
to be compiled by tomcat. However the Jasper documentation states to go
ahead to use Ant's jspc task to precompile then deploy! 

If you want to give it a go the Ant & Jasper documentation for jspc is all
you should need. 
http://ant.apache.org/manual/index.html 
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper-howto.html#Web%20Appl
ication%20Compilation. 
Also check out Maven - it has a web.xml merge function you could use to
fully automate a build,compile, deploy script.

You could also try the alpha Tomcat 5. Quoted from
http://jakarta.apache.org/tomcat/
"Refactored application deployer, with an optional standalone deployer
allowing validation and compilation of a web application before putting it
in production". 

I would be interested to hear how and what you do..

Cheers
Euan

Precompiling involves translating your jsp's to class files webapp build

I have never done precompiling in 4.X (so I don't the actual tech

JBossMQ vs JBoss (General Message Queue)

[Jason Efting]

Hi,
I'm busy reading some material on Message Queing and would like to get some opinions.
 
Does anybody have any experience using JBoss as a mesage queue broker toghether with 
Tomcat?
 
I downloaded JBoss and JBossMQ but cannot determince the difference?
 
Where can I get some documentation regarding the usage of a message queue with JBoss 
and Tomcat?
 
Basically, all I would like to do is have a web based interface where admin can view 
messages received and send messages to another message broker (Soniq or MQSeries)? Any 
ideas, docs or code snippets would be appreciated.

Jason

RE: Switching to virtual hosts gives permission error

[Dave Weitzel]

Jeff
Thanks for your feedback and idea.
I have eventually found that when you switch on NameVirtualHost then Apache
needs r-x permissions on all the folders in your tree.

I was running under /home/tomcat/tomcat3/webapps... and had mode 744 on all
directories except /home/tomcat (700 as you would expect)

Just so very odd given that 
a) tomcat is accessing this area - was running under user tomcat
b) Apache without the VirtualHost turned on was able to work fine.

Re: Run Tomcat not as root

[Yoav Shapira]

Howdy,
Tomcat is a java program: whatever runs the java command is what runs tomcat. 
So if you create a user named tomcat with permission to run
$JAVA_HOME/bin/java, you're pretty much all set.  Make sure the user has rwx
permissions to tomcat's logs, temp, and work directories, and at least read
permissions for all the webapps.

Re: Mailing List for Security warnings

[Tim Funk]

AFAIK there are no issues with the default install. But the default install 
does include the examples app - which allows any user to view your 
environment and probably set session variables which could easily allow a 
denial of service attack based on memory consumption.

But then again, if one leaves the example webapp available on a production 
box, someone is not doing their job since only absolutely needed webapps 
should be installed and available on a production server. (Why allocate 
memory for a webapp which shouldn't be used?)

Re: Mailing List for Security warnings

[Tim Funk]

Nope. Typically if a security issue is found, it will be discussed by the 
committers to confirm the vulnerability. A patch and a new release is made. 
The announcement of the vulnerabilty and the new release are usually made at 
the same time.

The annoucement is typically made to:
- tomcat-user
- tomcat-dev
- tomcat-announce (I think this is the name)
-Tim

precompiled jsp's as a part of application war file

[Rob]

I would like to bundle my application into a single .war file.
In addition I would like to include the precompiled .jsp files
in the war file as opposed to the .jsp files themselves.
Is there a way to do this?  I would like to deploy my
application to a target without a `javac`.
A description of how would be appreciated, particularly
where within my hierarchy I place the class files and how it
affects the requests for those .jsp files (ie can a person still
type in http://www.foo.com/myapp/my.jsp) or do they end up
being used as servlets instead?
Thanks

Re: Switching to virtual hosts gives permission error

[Jeff Knox]

Dave,

I saw something like that if I didn't put the virtual host directories 
in CATALINA_HOME/webapps/ROOT. I could live with that, but then I had a 
major problem. I couldn't get forms using POSTs or URLs with parameters 
to work (ex:  index.jsp?name=bob). Somebody recommended that move from 
mod_jk to mod_jk2. Mod_jk2 needs threaded Apache and instead of 
recompiling Apache 1.3 I upgraded to 2.0. The Apache 2.0/mod_jk2/Tomcat 
4.1 combination works great. The GET method works and I was able to 
move my htdocs directories back to their original locations.

I hope this helps.

Jeff

And now to my question. Why is that working? It doesn't seem that
 the uri tag in the workers.properties is used at all. I thougt that only
 request ending with /servlet/* would be forwarded to tomcat.

Re: Clear user session

[Yoav Shapira]

Howdy,
Something else is modifying the session (adding/removing attributes or
otherwise modifying the backing collection of your session_var enumeration)
while you're iterating through it.

>  while(session_var.hasMoreElements())
>  {
>  String key=(String)session_var.nextElement();

You need to make the above code synchronized on the session.  This may not be
as trivial as it sounds: for example, it might be impossible if your
environment is clustered.

Alternative options include doing this on session passivation or destruction
(probably the former), using the appopriate listener.  

Why are you clearing all the attributes instead of a specific one?

Hi,

You want the Apache Web Server for PHP not Tomcat, you can download this and 
find out more information from the below URL:

http://httpd.apache.org/

If you want all three Apache, Tomcat and PHP working together then you need to 
plug Tomcat into Apache with mod_jk2.

Re: Assessing Tomcat's State

[Yoav Shapira]

Howdy,
Note that the premise of your question is flawed without a precise definition
of "starting up" and "shutting down."  Consider a tomcat instance with N
webapps, each of which with one ServletContextListener.  Tomcat on startup will
send the contextInitialized event to each of these listeners.  Each listener
may do things that take a long time, and may or may not do them in the
background.  

In the above scenario, when is the "starting up" state over and the "started"
state entered?  Is it when tomcat sends all N events, or when all N events are
done processing?

Similar scenarios can easily be construed for shutting down, and they are not
limited to listeners as filters and servlets can all do varying amounts of
processing on startup and shutdown.

All of this may not matter in your scenario, so you may not have to worry about
it at all ;)  But they are important to keep in mind if you're trying to come
up with some sort of general solution.

tomcat and isapi

[Christopher Scaffidi]

Dear Sirs and Madams--

Have you had any luck recently in running Tomcat as an ISAPI plugin (by
extension)?  We are having problems with cookies being dropped when running
as a plugin, and any suggestions you might have would be deeply appreciated.

Thanks,

Clear user session

[shyam]

Hi All,

I just moved my webapp from jrun to tomcat. I have a method which clears the
user session. The code snippet is

 Enumeration session_var = session.getAttributeNames();

 while(session_var.hasMoreElements())
 {
 String key=(String)session_var.nextElement();

I am getting an error here and the exception is

java.util.ConcurrentModificationException at
java.util.HashMap$HashIterator.nextEntry

How can I resolve this error.

Thanks a lot in advance
shyam

RE: Help Please: Starting Tomcat using channelUnix with mod_jk2

Thanks Mark,

I tried it on RH Linux 9.0 with the same result myself. I bet your thought
on the recent change on the apr_md5_final is probably correct... no what can
we do about it???

Pascal,

I've been trying the same thing with Redhat 9, and
getting a similar problem.  I even put
/home/apache/lib in /etc/ld.so.conf and ran
/sbin/ldconfig -v.  I verified that that shared
libraries are indeed loaded.

I also tried modifying /home/tomcat/bin/catalina.sh to
include a -Djava.library.path=[various things], but
that failed to work as well.

I'll think about it some more tomorrow.

One thing to note:  In the source code, there has been
a recent change from apr_MD5FINAL to apr_md5_final.
I'm wondering if the propagation has made it all the
way through.

/mde/
just my two cents . . . .

Thanks Chong,

Yes, I did make the symbolic link as you mentioned.  Now I have a question
for you. In your server.xml file, in the connector definition, you are still
using port 8009. When using channelUnix shouldn't the port be set to 0
(zero)?

Michael

Something occurred to me last night -- I forgot to remind you about a
certain symbolic link you need to make. You see, RH8 names the APR file
differently. Not sure if you did this :

*# ln -s /usr/lib/libapr-0.so.0.9.3 /usr/lib/libapr.so.0

*Regards,
pascal chong
