Re: Running Tomcat for Multiple developers

[tsmets]

Don't you have a simple sys admin problem ?
As working under Unix / Linux soft links should give you some possibilities,
shouldn't it ?
A little shell-script like this ?

1°. mount ont /opt an nfs-shared d-rive where the common read-only
install is
2°. add a link there where webapp is a local dir
  Smthg like ln -s  /opt/tomcat/webbapp ~/data/webapp
(U have therefore in your userspace a reference to your own data
which are viewed as the Tomcat webapps directory)
3°.Add similar soft-links for the logging directories & other user
specific files / directories

You end up with every user sharing one remote install of Tomcat ith there
own environement  !
How to do under Zindozs :-))  dunno !

Thomas,

RE: Configuring apache + tomcat on separate machines

[Anton Brazhnyk]

Hi,

I've done it. Its easy if you read docs carefully. I did it with
both mod_webapp and mod_jk. (RedHat 7/Apache 1.3.20 + Win2k/Tomcat 4.0.2)

All the steps are pretty straitforward except maybe workers.properties.
Here is mine:

ps=/

worker.list=AJP13

worker.AJP13.port=8009
worker.AJP13.host=192.168.3.20
worker.AJP13.type=ajp13
worker.AJP13.lbfactor=1

in httpd.conf you have to LoadModule mod_jk.so and add something like
following (end of file is working for me)

JkWorkersFile /etc/httpd/conf/workers.properties
JkLogFile logs/ajp.log
JkLogLevel error

JkMountCopy on

JkMount /tests/* AJP13
JkMount /tests AJP13

JkMount /manager/* AJP13
JkMount /manager AJP13

JkMount /tomcat-docs/* AJP13
JkMount /tomcat-docs AJP13

Hope it helps.

Do you want to remove it or redirect it?
If you remove it you won't be able to access that port and thereof do
redirections. All you need is to remove or comment out Connector
with port="8080" attribute in server.xml
If you want to redirect requests from 8080 to 443 you have to
add/change the redirectPort attribute in that Connector and
add some SecurityConstraints to web.xml in your application.

These topics are covered in the SSL HOWTO of TC docs and
in Servlet Specification (Security)

RE: ASP and JSP with no redirection

[Sergei Batiuk]

There is an option:

You can use the io taglib from http://jakarta.apache.org/taglibs, which
makes it possible
to make up a page from various sources. Your JSP should look like:
<%@ taglib uri="iotags" prefix="io"%>

<%
myEJB.myMethod();
%>
http://iisServer/m$Page.asp"/>
<%
java().stuff().again();
%>

This way you can create a single page from any http/ftp/file resources you
can think of.

Sincerely,
Sergei Batiuk.

Subject: ASP and JSP with no redirection


Hi All,

Just wondering if there is another way to integrate both JSP and ASP
together in the one page without redirection through a specific port.

Is it possible to combine both an ASP and JSP page together thus giving you
the ability to access a COM and EJB object on the same page ?

I know this sounds crazy but if it is possible then I would imagine its
something that needs to  be configured at the web server level such that
each Object method request is handled by its respective web server.

foo.JSP
<%

 ... myEJBBean.Method() ...
 ...myASPObj.Method()...

%>

Lets say our example is implemented on a JSP page then Tomcat/Apache will
need to know about IIS such that it passes the processing of
"myASPObj.Method() " to IIS. (no redirection)

Many thanks in advance for any feedback.

George Shafik

More information: Getting Apache to Stop Buffering my Servlet Output

[Bill Neuman]

Sorry for the spam, but it might be significant to know what
versions of stuff I'm using.

Tomcat 3.2.3
Apache 1.3.19
jdk1.3.1
Windows NT SP6a (although I believe in the distant past
I verified this issue on Solaris as well)
Using mod_jserv, not mod_jk as the connector

These versions, and the use of mod_jserv are required by
the java application I'm developing with (according to
its documentation).

I notice that this problem DOES NOT occur if I replace mod_jserv
with mod_jk.  So, I just need to know if there is a solution that
works for mod_jserv (ideally the solution will be some
different usage of the java methods & objects on the servlet
or JSP side).

Thanks again.

RE: ASP and JSP with no redirection

[Deacon Marcus]

Hi,
This not only sounds crazy but it is crazy. Suicidal even. If you absolutely
must do something like that try searching for Java-COM bridges, "simply"
mixing jsp and asp is not possible by definition, but it is possible to
access COM objects from .jsp via various Java-COM bridges. I suppose the
opposite (Java beans/EJBs from .asp) is also possible.

RE: Running Tomcat for Multiple developers

[Ricky Leung]

You can have multiple instances of tomcat with 1 installation but every
instance *must* have their own instance.

To do that, simple set JAVA_HOME to where java is installed and set
CATALINA_HOME to be where tomcat4 is installed and lastly, set CATALINA_BASE
to be that user's home directory/tomcat.

Under CATALINA_BASE, there should be a conf, logs, webapps, and work, same
as the Tomcat install should have in order to run.  Each student can then
have their own complete set of webapps and server.xml as if there's only 1
instance on the server.  But, again, the server.xml will have to use
different port numbers.

Then each student simple runs $CATALINA_HOME/bin/startup.sh and
$CATALINA_HOME/bin/shutdown.sh to start/stop tomcat, respectively.

You should provide them with an example of server.xml that they should place
under conf/ and have them just edit the port number.  Your sample should
only have 1 service and you can delete the bottom  tag used for
apache integration.

The Tomcat4 documentation area has more detail info on this under the
configuration section.

RE: Popup Browser Windows & Tomcat Realm Authentication

[Ricky Leung]

I'm not sure if this would work, but I am guessing that your popup
immediately opens and your original window didn't do a thing.  If you allow
your parent authenticate and go to a authenticated page, it would be fine.
Then simply have that page popup the window that you wanted.  This idea is
similar to the way many sites having an auto-popup of advertisement when you
enters their main page.  Give that a try.

Yes, the content which is protected through a security constraint is marked
as non cacheable (which fixes a security problem where a proxy would cache
the pages).

Let's try this again: Getting Apache to Stop Buffering my Servlet Output

[Bill Neuman]

Oops - I tried to use Hotmail to post because my primary ISP's mail
server is down, and it mangled my JSP page.  So I'll repeat the
question...


All, 

This is a question that has been repeated several times on this mailing 
list, but as far as I can tell never answered. 

I have a long back-end process during which I want to return interim
results to the browser.  With a JSP, the standard way to do this seems
to be to use out.flush() at any point where I want to return partial
results.  This works great when I browse Tomcat's own web server
(port 8080), but when I browse the same page served through Apache
(port 80 for me) and serviced by Tomcat, the results all appear at
once, rather than as I flush() them. 

So, it appears Apache is adding some level of response buffering that
I'm not asking it to do.  Does anybody know how to make this work. 

Below is the code for a jsp page that demonstrates the issue--all help
is appreciated. 

---BEGIN CODE--- 
<%@page language="java" session="false"%>


Delaying

Delaying...
The following lines should appear at approx.1 second intervals.
When served through Tomcat's own server (i.e. 8080) it works.
When served through Apache using Tomcat as the handler, the page all
appears at once after an approx. 5 second delay.

<%
out.flush();

long delay = 1000;
long start = System.currentTimeMillis();

for (int ii = 1; ii < 6; ii++) {

P.S. I've also tried request.flushBuffer() based on responses
to one of the previous questions about this, but that is even
worse--if I use it, the "chunked" behavior doesn't even
work when browsing Tomcat's own web server.

Did the default HTTP expires header change in Tomcat?

[Jonathan Eric Miller]

In the applications that I'm developing, I used to be able to click on the
Web browser back button to return to a page that contained form data that
was generated by a HTTP post. I noticed that it now gives me an error
message like "Page has Expired" when I try to do it. It does this in both IE
and Netscape. It never used to do this. Did the behavior in Tomcat change?

If so, what do I need to do to return to the previous behavior? Set an HTTP
header like "expires" or something?

I noticed the following in the release notes in the fixed bugs section.
Could this have something to do with it?

6151  Manager servlet behaves bad in IE without an "Expires: -1" http header

Not finding class, mistakenly looking for "null"

[James Adams]

Hello,

I have a web application which is not finding a tag handler class, it is mistakenly 
looking for "null".  The classes for this tag
handler is located in the WEB-INF/classes directory and is declared in web.xml.  The 
web application works as advertised on another
system which is running Tomcat version 4.0.1.   This server is also at version 4.0.1 
but obviously it still needs some
configuration before things are as they should be.

Some things to consider:

* The front page of my application is a JSP which appears as it should.
* The default Tomcat page, index.html doesn't appear when I try http://localhost:8080, 
I get a 404 Not Found message
* When I go to a page which utilizes the custom tag I get the following exception 
messages:

org.apache.jasper.compiler.CompileException: 
/var/tomcat4/webapps/dataview/Level2InteractiveSelect.jsp(48,8) Unable to load class
null
at org.apache.jasper.compiler.TagBeginGenerator.init(TagBeginGenerator.java)
at 
org.apache.jasper.compiler.JspParseEventListener$GeneratorWrapper.init(JspParseEventListener.java)


The tag library class is properly declared in web.xml and has a proper tld in 
WEB-INF/tlds, or at least I think it is proper since
it is working on the other machine which is running version 4.0.1.  Perhaps I have my 
jsp or tlib versions in the tld mixed up
?  Here's the tld for the taghandler in question:

Can anyone suggest what to do or where to look in order to figure this out ?  This is 
an upgrade from Tomcat 3.2.1, perhaps there
are old files from the previous version which are wreaking havoc ?  The system in 
question is running Red Hat 7.2 and when I enter
the following command

rpm -qa | grep tomcat

I see both versions present.  Perhaps I should remove the tomcat-3.2.1-1 RPM ?

Thanks in advance for any suggestions.

Tomcat 4.0.2 problem with JDK 1.2.2

[Adrian Prezioso]

I have installed Tomcat 4.0.2 running with IIS 5.0
using JDK 1.2.2.  Tomcat starts fine, but when I make
a request to my application, I get the following
error:

java.lang.NoSuchMethodError: java.net.Socket: method
setKeepAlive(Z)V not found
at
org.apache.ajp.tomcat4.Ajp13Connector.run(Ajp13Connector.java,
Compiled Code)
at java.lang.Thread.run(Thread.java:479)

I then changed the JDK to 1.3.1 and I no longer get
the exception, but my application doesn't work
properly because it requires 1.2.2.  I can't
understand why JDK 1.2.2 seems to be the problem when
it clearly states in the Tomcat documentation that it
supports 1.2 and higher.  Any ideas how I can get
Tomcat 4.0 to work with JDK 1.2.2??

Getting Apache to Stop Buffering my Servlet Output

[Bill Neuman]

All,

This is a question that has been repeated several times on this mailing 
list, but as far as I can tell never answered.

I have a long back-end process during which I want to return interim results 
to the browser.  With a JSP, the standard way to do this seems to be to use 
out.flush() at any point where I want to return partial results.  This works 
great when I browse tomcat's own web server (port 8080), but when I browse 
the same page served through Apache (port 80 for me) and serviced by Tomcat, 
The results all appear at once, rather than as I flush() them.

So, it appears Apache is adding some level of response buffering that I'm 
not asking it to do.  Does anybody know how to make this work.

Below is the code for a jsp page that demonstrates the issue--all help is 
appreciated.

---BEGIN CODE---
<%@page language="java" session="false"%>


Delaying

Delaying...
The following lines should appear at approx.1 second intervals.
When served through Tomcat's own server (i.e. 8080) it works.
When served through Apache using Tomcat as the handler, the page all
appears at once after an approx. 5 second delay.

<%
out.flush();

long delay = 1000;
long start = System.currentTimeMillis();

for (int ii = 1; ii < 6; ii++) {
   while (System.currentTimeMillis() < start + delay) {
   }
   start = System.currentTimeMillis();
   %>
   Delayed a total of <%= ii %> intervals.  Pretend this is a message
   giving status on task execution in a long string of tasks.

   <%
   System.out.print(" ii=" + ii + "; ");
   out.flush();
}

System.out.println("");
%>

Tomcat 3.3a and context loading order

[Mario Felarca]

Hello,

In Tomcat 3.2.x one could specify the order in which contexts were 
initialized by the order in which they were entered in the server.xml file.

In Tomcat 3.3 I have not found a way to do this yet, short of putting the 
contexts into one file (be it the server.xml file or an apps-ordered.xml 
file). Does anyone know of a better way to do this?

Thanks in advance,

Re: mod_jk: Auto reloading workers.properties file.

I'm not sure... :) I only just got it working, so I'm still testing it.

Every time an endpoint to a tomcat is requested I stat the
workers.properties file, if it has changed, the load-balancer
reconfigures itself. The reconfiguration does cause a small delay
response to any incoming requests as mod_jk has to open a new socket to
the desired tomcat.

Put it this way, I think it is quicker to reload the load-balanced
workers than to do a graceful apache restart. It is also cool to edit
the properties file, save it, and watch an immediate change in the
results coming to the script hammering your website... :)

I'm thinking about adding a minimum time between stats on the
workers.properties file. :)

Note: Currently the code only supports reconfiguring workers that are
under a load-balancer.

I guess this functionality is only required if you are frequently changing
the workers.properties file for some reason.

Anyone got any other ideas/requests and more importantly advice?

Jonathan.

tomcat4 and load balancing with apache

[Ricky Leung]

Hi,

I am getting mixed answers from the documentations.  Does Tomcat4 support
load-balancing with mod_jk?  I know it doesn't with mod_webapp but any idea
when that feature will be out?  Also, in the release notes, it says that
there is now a Webapp 1.0.2, where can I download this?  I only see the one
in Tomcat4.0.1 but it's webapp-module-1.0, not 1.0.2.  I also looked at the
src of the connectors but not in there either,
jakarta-tomcat-connectors-4.0.2-01-src.

Thanks.

null DataSource when trying to get JNDI InitialContext

[George M. Coles]

Hi all,
I am using tomcat for the firs time. I have v. 4.02, using jdk 1.4.

I am attempting to deploy my app, which uses JNDI to look up a connection
for its data access. I am using DB2 I have  placed the db2 jdbc zip file in
my WEB-INF/libs dir. My server.xml looks like this:






driverClassName

COM/ibm/db2/jdbc/app/DB2Driver


driverName

jdbc:db2:PATHLINE


user
db2admin


password
password






When I do my context lookup, which should return a DataSource, the
DataSource is null. I do not, however, get a naming exception, as I would
expect if the resource could not be found.

Has anyone had a similar experience? I am not quite knowlegeable enough
about JNDI or Tomcat to see where my problem is.

thanks,
George Coles

RE: Error Executing JSPs

Without modifying the startup script I don't believe this will help
- Tomcat ignores any CLASSPATH variable you might have set.  Instead, the
JAVA_HOME must be set so that JAVA_HOME/lib/tools.jar is valid, or tools.jar
needs to be copied (or symlinked) to the TOMCAT_HOME/lib/container
directory.

RE: Error Executing JSPs

[KC Berg]

One more thing make sure that the JAVA_HOME/lib/tools.jar is in your
CLASSPATH.

I've just installed Tomcat 4.0.2 binaries rpm on a RedHat 7.2 linux machine
with Sun J2SDK1.4.0.
I installed the following rpms:
regexp-1.2-1.noarch.rpm
servletapi4-4.0.2-1.noarch.rpm
xerces-j-1.4.4-1.noarch.rpm
tomcat4-webapps-4.0.2-1.noarch.rpm
tomcat4-4.0.2-1.noarch.rpm
The installation is pretty straight forward but I'm having problems
executing the JSP examples.
The servlets executed just fine but when I try to run the JSP examples I get
the exeption bellow.

Any help on pointing out what I'm missing will be greatly apreciated.
Thanks

mod_jk: Auto reloading workers.properties file.

[jonathan]

Hi all,

I've written a small patch for mod_jk that automaticly reloads the
workers.properties file when ever it is changed.

Currently it only works with apache-1.3 but it trivial to make it work
with the others.

Is anyone interested in using this patch?

Jonathan.

Troubles with the list: 

tomcat 4.0.2 compiling client auth source ?

[Stephen_Magennis]

Hi
  I know in the tomcat 4.0.2 source code, the line in
SSLServerSocketFactory.java
for enabling the trustManagerFactory is commented
out this disabling the client authentication capability.

// Create the trust manager factory used for checking certificates
/*
trustManagerFactory = TrustManagerFactory.getInstance(algorithm);
trustManagerFactory.init(keyStore);
*/

Is this functionality definitely unusable at the moment ?
Is it possible to uncomment the lines and recompile with the
TrustManagerFactory to enable client authentication ?

Any anticipated timeline when 4.0 client authentication will be enabled.

Any info/direction would be greatly appreciated as we are trying to do
client authenication with tomcat standalone without having to go the
apache/tomcat router.

Many Thanks
Stephen

Re: Configuring apache + tomcat on separate machines

[Keith Simpson]

Try workers.properties file - that is read by the mod_jk module (via the
include directive in the httpd.conf)  I think and has host settings for
ajp connectors.  As I said, never done it, but gotta work somehow!

RE: reloading classes - rephrase

[Larry Isaacs]

There were some reloading problems encountered with URLClassLoader in Tomcat 3.3.
A new attribute, use11Loader,  was added to  as a workaround.
If you can, give Tomcat 3.3.1 Beta 1 a try with use11Loader="true" and see if you
still have the problem.

See:



for details.

Cheers,
Larry

The DTD doesn't just declare what elements are legal -- it also defines
the *order* in which the elements must be presented.  Put things in the
right order and it will work fine.

Can you provide an example of what you mean by this?  Tomcat's JSP
compiler renders HTML comments only if you include them in the original
JSP page (or you use a custom tag that creates them) -- it doesn't add or
remove any by itself.

RE: changing a user's password on linux using jsp exec.

[Dahnke, Eric]

Do a man chpasswd from the linux command line. See the format it expects
(user_name:password). Just write the username and pw into a file using that
format from your tomcat app. (say the file is: /tmp/new_pw). chown new_pw to
nobody.nobody or chmod it 666.

Then in your /etc/crontab file add:

05 * * * * root chpasswd /tmp/new_pw

This will run the chpasswd as root every 5 seconds. Actually rather than
calling chpasswd from cron I would create a shell script that does some
checking to make sure that your web app isn't trying to change the pw for
root or any other important system users. And that also empties the file
new_pw after chpasswd is run. Be careful. Don't look yourself out of your
machine on my account ;->

I have no idea if this is even possible, so I'm afraid I can't be of much
help.

Given that WebLogic has its own servlet/JSP container built in (as does
the J2EE RI and every other J2EE app server), it would actually surprise
me if WebLogic went to the effort required to make this work.

Can someone please explain to me why such a thing is needed?

how would the apache server know on which IP address the tomcat is running?
from the tomcat side it is fine, but how about the communication from apache

Would think it would have to be possible.  since they communicate via
ajp protocol, you just need to specify something other than localhost on
the tomcat side I would think.  the ajp stuff has default ports of
something like 8007 and 8009.

RE: changing a user's password on linux using jsp exec.

[Dahnke, Eric]

The only password you could ever change is the one for the user Tomcat is
running as (nobody i believe).

I've been down the road you're going down. Your options are:

-1- (compiling apache/tomcat to run as user root (unreasonable on anything
other than a intranet environment). big security hole.
-2- you can use the expect programming language. 
-3- you can hand the passwd execution to a cron job that runs as root. just
dump the user to change password into a text file. grep the text file every
5 seconds or something from cron. if an entry exists chpasswd on it and
delete the entry from the file. cron is very light weight. see man chpasswd

RE: changing a user's password on linux using jsp exec.

[Randy Layman]

1.  I believe that you want a PrintWriter or add \n to the end of
the passwords (the user presses enter when running passwd).  This is
probably causing your symptom of nothing happening (passwd waiting for you,
you waiting for passwd).
2.  Only some users (maybe just root) can change other user's
passwords.  You will need to run Tomcat as root, which introduces its own
set of security issues.

RE: reloading classes - rephrase

[tamir]

Hello again,

Thank you very much for your quick response.

I read your answer and tried to refresh classes in the web-inf/lib.

Nevertheless, when I override an already existing myxxx.jar file (in
web-inf/lib) with a newer version tomcat 3.3 gets crazy.

Our application is loading a class from myxxx.jar using Class.forName and
activates some methods in it.
Everything is going well until we override myxxx.jar with a newer jar (class
interface hasn't been changed).
Tomcat is refreshed well (although, losing session), however, when accessing
again the class in the jar,
I get the following exception:

The answer is simple:  no.

Java provides no mechanism for unloading a class that has already been
loaded.  The way that reloading is implemented for a webapp is to throw
away the entire class loader used to load that webapp, and starting over
again.  If we did that for shared classes, however, you'd have to restart
*all* webapps because they would all need to be thrown away.

If you want to take advantage of the auto-reload capability to update
classes in a webapp, you *must* put those classes in /WEB-INF/classes, or
in a JAR file in /WEB-INF/lib.

RE: security-role-ref not working with Tomcat 4.0.1 & .2

[Kapasi, Mehjabin]

I was also getting the same error although it was with the  tag. I
followed the DTD correctly but still could not get rid of the error.
I commented that section out and it worked like a charm with no errors. I am
not sure if that is because of some tag library issue in Tomcat 4.0.1.
If you also have a tag library associated, try commenting it out and see if
that works.

Cheer up Craig.  I don't think I've ever asked a question on the list

Compression Filter Performance

[Yoav Shapira]

Hi,
I have a compression filter (variation of Jason Hunter's JavaWorld
article filter) working exactly as I want it to.  It wraps the
response in a GZIP output stream (if the client can handle it,
and the compression threshold is exceeded), and the client deals with
it.  

My question is, how can I measure how compressed my response is 
versus running without using the filter?  (I don't mind recycling
the server and changing web.xml between runs).  

Thanks in advance,

J2EE and Tomcat

[Reynir Hübner]

hey guys..
 
On that matter (J2EE & Tomcat), I've noticed one "small" difference
between Tomcat and the jsp spec. 
Tomcat renders jsp-code that's between , the HTML comment tag. 
this means that Javascript especially can be commented out of the HTML
for old browsers while some of the javascript code is generated by
jsp-code.

In other J2EE servers I've looked at like orion and websphere they do
not render jsp-code with in HTML comment tags. 

why is this different in tomcat from others and the spec ? Or am I not
understanding this correctly ?

Well this is not a big problem (not for me at least), but I assume many
people are using tomcat as a developement tool, and if they are
developing something accordingly to how Tomcat handles it, they might
face a problem when migrating to other J2EE servers... but then again,
they haven't been developing according to the spec... 

... so, why break the spec ?

thanx

Re: J2EE and Tomcat

[Keith Simpson]

Yaaay!  Finally an answer!  Thanks Craig.  I knew that substituting jars
was not kosher, but I love to experiment.   The approach actually worked
6 months ago when I was experimenting with implementing mail on my TC
3.2 server.  I would "never,never,never" go to production with such a
hair brained scheme!   I thought I had seen somewhere that TC 4.0x was
J2EE 1.3, but could not "refind" that information.

I was aware I could get javamail and that there was some extension (must
be the one of which you speak) to use the mail tags in jakarta-taglib. 
The link specified in the taglib docs was dead - I assumed that sun just
decided to wrap it all up into j2ee.

once again, many thanks.

If you need classes to be visible to *both* Tomcat and your webapp, put
them in $CATALINA_HOME/common/classes (or in JAR files in
$CATALINA_HOME/common/lib).  For more information on how class loading
works in Tomcat 4, see the appropriate docs:

  http://localhost:8080/tomcat-docs/class-loader-howto.html

or online at:

No, it is not a bug.  Security constraints only apply to the *original*
request URI from the user.  Applications are assumed to know what they are
doing -- if the app doesn't want the user to follow a particular forward,
it shouldn't execute that forward.

Yes.  All you need to do is create a  element in server.xml for
each element, and put the  element for that application inside it.
The gory details are in the Server Configuration Reference, which is
available once you start up Tomcat 4 at:

Re: Compilation error with ant...

[Craig R. McClanahan]

The "[javadoc}" at the beginning of each line tells you that this output
is coming from the  task in the Ant build.xml script, which
(surprise surprise :-) runs JavaDoc.  JavaDoc will complain like this when
your code has a reference to classes external to the package, when it
doesn't know how to create the corresponding hyperlinks.  It just issues a
warning and makes those references static text instead.

The BUILD SUCCESSFUL message is the important part.

Apache+Tomcat and the RewriteRule

[Jarecsni János]

Hi,

how can I use Apache mod_rewrite to alias a dynamic resource (to be served
by tomcat thru ajp)???

RewriteRule !^/istore(.*) - [C]
RewriteRule (.*) http://my.virtual.host/istore$1 [L]

is not good since it handles the URL as a file after rule is matched (so it
prepends the document root, instead of passing the request to Tomcat [I have
the appropriate JkMounts]).

(2) init rewrite engine with requested uri /control/main
(3) applying pattern '^/istore(.*)' to uri '/control/main'
(3) applying pattern '(.*)' to uri '/control/main'
(2) rewrite /control/main -> http://my.virtual.host/istore/control/main
(3) reduce http://my.virtual.host/istore/control/main ->
/istore/control/main
(2) local pathresult: /istore/control/main
(2) prefixed with document_root to
f:/jboss-2.4.4_tomcat-4.0.2b/jboss/deploy/istore.war/istore/control/main
(1) go-ahead with
f:/jboss-2.4.4_tomcat-4.0.2b/jboss/deploy/istore.war/istore/control/main
[OK]

I tried the [P] flag to proxy it:

RewriteRule !^/istore(.*) - [C]
RewriteRule (.*) http://my.virtual.host/istore$1 [P]

So we redirect the newly rewritten URL to ourselves back, for another round
of processing (which in deed will activate tomcat). The problem: cookies are
lost with this approach.

I tried a few other lists and archives but found absolutely nothing.

thanks
János

RE: J2EE and Tomcat

Hi Craig,

I posted a question to this group regarding getting Tomcat 4.0.2 and
Weblogic 6.1 to play together, particularly with the Pet Store application.
I've been working at this issue for several days now with no solution.

Are you aware of any configuration "gotchas" that might affect splitting
petstore functionality to have Tomcat 4.0.2 serve jsp & servlets while
having Weblogic 6.1 provide data services?

Thanks in advance,

Steve...

Tomcat 3.2 (and 3.3) are based on the Sevlet 2.2 and JSP 1.1
specifications (these match up with J2EE 1.2).

Tomcat 4.0 is based on the Servlet 2.3 and JSP 1.2 specifications, which
are the versions included in J2EE 1.3.  In general these specs are
backwards compatible so that your older webapps will still run.

If your applications don't require EJBs, it is very reasonable to do your
development under Tomcat and then deploy on a J2EE server.  Just be sure
you don't rely on Tomcat-specific features in your applications.

Never ever ever ever should you be replacing system JAR files like that!
The j2ee.jar file from the J2EE RI includes a version of Tomcat already,
so you are just duplicating a whole bunch of classes and it is
going to cause runtime conflicts.

If you just need JavaMail, the smart thing to do would be to go download
JavaMail and add the appropriate JARs to Tomcat
.  You will also need the Java
Activation Framework package -- a link is provided on this page.

Tomcat 4 releases include the JavaMail and JAF jar files already.

Hi,
to start tomcat in a separate window use
"$CATALINA_HOME/bin/catalina.sh start"

to stop tomcat use
"$CATALINA_HOME/bin/catalina.sh stop"

It works fine so you don't need to wait for ending the tomcat process.

Subject: restarting Tomcat 4


Hi.

 I was wondering if anyone out there has a good way of restarting Tomcat
4...?  In version 3, I used to just be able to do
"$TOMCAT_HOME/bin/shutdown.sh; $TOMCAT_HOME/bin/startup.sh".  Now, in
version
4 though, since the starting and stopping scripts seem to have been modified
to be background processes, this no longer works since it won't wait for the
first script to finish anymore before starting the second one.  Now, my
restart alias looks like this: "$CATALINA_HOME/bin/shutdown.sh; sleep 40;
$CATALINA_HOME/bin/startup.sh".  Pretty lame, and I just arrived at the
sleep
value by trial and error (actually as I add more stuff in my server.xml
file,
I think the shutdown might even take longer, so I may need to bump this
value
up).  Does anyone have any more elegant/exact ways of doing this?

Thanks,
-Jeff

Hi Franck - I've done exactly that with a copy of DB2 Everyplace and Tomcat - simply 
edit your server.xml file as follows:

Find the default logger configuration line

  

and change it to instead log everything to a console window

  

You'll get to see all the startup and error messages, but at least it doesn't write to 
the disk. Even our sales team can cope with this for demoing our software! Hope it 
helps,

Alex

Hi,
I am new to tomcat and uses the 3.2 version to make a web application.
I'd like to run tomcat from a cdrom on a windows boxe :
   after having tested my application on the hard disk, I have put the
tomcat tree on a cd with a jvm and and launched the startup.bat script
that launches tomcat
It seems that tomcat wants to write in the log directory and also in the
conf directory.
Is it possible to make a specific configuration and launch tomcat sothat
it does not try to write any files and run from a tomcat directory tree
on a CDROM ?

regards,
Franck

   after having tested my application on the hard disk, I have put the
tomcat tree on a cd with a jvm and and launched the startup.bat script
that launches tomcat
It seems that tomcat wants to write in the log directory and also in the
conf directory.
Is it possible to make a specific configuration and launch tomcat sothat
it does not try to write any files and run from a tomcat directory tree
on a CDROM ?

regards,
Franck

Re: Configuring apache + tomcat on separate machines

[Keith Simpson]

Would think it would have to be possible.  since they communicate via
ajp protocol, you just need to specify something other than localhost on
the tomcat side I would think.  the ajp stuff has default ports of
something like 8007 and 8009.

problem configuring security appn with Netscape Directory Structure

[jay n gaba]

hi
I am trying to run the sample security example (i.e 
http://localhost:8080/examples/jsp/security/protected/)
using netscape directory structure.I can connect to ldap but while trying to connect 
to the application I receive an invalid user or password error.
I have successfully connected through an ldap browser.
Netscape Directory server has been configured to use the SHA algorithm for encrypting 
the passwords.I read some previous archives which suggests that there is some problem 
while comparing the passwords.I have tried removing passwords but still it throws the 
same error.

Can anyone give me some direction on this.??? I have pasted below the realm 
configuration and a sample entry in the ldap. I have used the sample entry given by 
the tomcat site.

Thanks in advance

Jay

ldap://abc2.xyz.org:8389/o=abc.org";
roleBase="cn=roles,o=abc.org"
roleName="cn"
roleSearch="(uniqueMember={0})"
roleSubtree="false"
userPassword="userpassword"
userPattern="cn={0},o=abc.org" 
digest="SHA"/>

ldap entry :

# Define a user named 'tomcat'
dn: cn=tomcat,o=abc.org
cn: tomcat
userpassword: tomcat
sn: Tomcat User
objectClass: person

Re: CDROM applications with tomcat

[jeff . guttadauro]

Hi, Franck.

 I'm not sure if this would work, but maybe you could try to define a
$CATALINA_BASE that is on the hard disk while keeping the $CATALINA_HOME
pointed to the CD...?  Just a thought.

Good luck.
-Jeff

Deploying wars using Manager

[John Wadkin]

All,

Is it possible for me to deploy a Web App stored on my Windows NT machine to
TomCat running under Unix using the Manager Web App? The docs (as ever)
aren't clear on if this can be done and how. If not, then what's the point
of the Manager app? 

Thanks,

John

There is a just-barely-started effort within the Jakarta Commons project
to create a package of nice, reusable, Filters.  Caching is one of the use
cases (and it will need more than one implementation, because different
applications will have different requirements), but no code has been
submitted yet.

This will be discussed on the COMMONS-DEV mailing list -- see
 for subscription information.

For compression, there's an output filter that does this for you included
in the example app of Tomcat 4.  You can rip it out and use it in your own
applications as well.  (Yes, this is going to be contributed to the
Commons package once it's up and running :-).

The answer is simple:  no.

Java provides no mechanism for unloading a class that has already been
loaded.  The way that reloading is implemented for a webapp is to throw
away the entire class loader used to load that webapp, and starting over
again.  If we did that for shared classes, however, you'd have to restart
*all* webapps because they would all need to be thrown away.

If you want to take advantage of the auto-reload capability to update
classes in a webapp, you *must* put those classes in /WEB-INF/classes, or
in a JAR file in /WEB-INF/lib.

RE: Scale Tomcat-Apache - Is this true?

[Ming Fai]

to my understanding, tomcat 4.02 beta has fixed the mod_jk load balancing
problem. The newly released 4.02 should support load balancing, could
somebody confirm this?

I found this on the internet. Is this true. Is there a workaround to this.

If I do go back to TC3.3, what do I gain/lose in terms of functionality and
performance.
