This is a valid question. You would have to override some of Struts 
functionality, locate where it loads config files and add a hook for 
decryption. Not a trivial task, but should not be impossible. The 
biggest issue with this is that by doing so, you're creating your own 
Struts port/branch and you would have to maintain it plus all upgrades. 
Switching over to a newer release of Struts would require you to build 
your Struts again, with the your changes.


Not something I would recomend. And again, it is not impossible to 
crack. In my oppinion, it is not worth the time, unless your securtity 
requirements are really high. But then, the machine's security is 
probably more important than encrypting config files.

If you are learning JSP you can connect to a database using JDBC. It
is same as using JDBC in any other java application. What you should
take care is to put the JDBC driver library in the WEB-INF\lib
directory of the application so that Tomcat sees it.

Classes in tomcat/common cannot load org.apache.catalina.*

[Ken Johanson]

Hello,

I'm looking for a way to be able to load classes in org.apache.catalina, 
like in Yoav Shapira's Tomcat Realm example ( 
http://wiki.apache.org/tomcat/HowTo#head-42e95596753a1fa4a4aa396d53010680e3d509b5 
).


The problem is, when my compiled classes (which wrap that entire 
operation) are packaged and placed into 'common', I get a 
NoClassDefFoundError: org/apache/catalina/ServerFactory.


Is there a config that will allow that classloader to access the 
server's libs?


I *can* load the server libs if I place the same wrapper class into the 
webapp's classloader, and have privileged=true for the host's context... 
however this is less than ideal since I would like for the class to be 
available to all webapps (when the privileged=true privilege is granted).


Thanks,
ken

tomcat 5 and cgi execution

[Linda Solomon]

Hi,

I am upgrading from tomcat 4 to tomcat 5.

I have a combination of java apps, applets and cgi programs written in 
perl and c++.

My web-application worked just fine with tomcat 4.

I followed the instructions for configuring tomcat 5 for cgi.
However, tomcat 5 contains a new xml variable:
executable - The of the executable to be used to run the script. Default 
is perl.


Using the default allows the perl cgis to work fine, but the c++ cgi's 
do not work.
Changing the executable value to /bin/csh or /bin/sh and none of the 
cgi's work.

Perhaps because the environment isn't set?

What are my choices for the executable parm?
What value will make my perl scripts AND c++ programs work?

Thanks,

Linda

It appears you're not using J2SE 5.0 on your machine.  Best to download

Next time, also best to "ask questions the smart way":  Let us know the

Much of this information you provided after being asked, but your

Thanks for trying to help Rob, per my original post I've implemented all 
points in this post and then some. From the original post:


The current configuration:

1) Not using APR, sendfile should not be an issue
2) My locale is set: "export LC_ALL=en_US.utf8"
3) File encoding is set for the JDK: "-Dfile.encoding=UTF-8"
4) contextDefaultEncoding is set to "UTF-8" in the global web.xml
5) I've created a Filter to explicitly set the type as per:

-- added per Mark's suggestion --

6) Added fileEncoding to init-param of DefaultServlet

In some additional testing, I've also got files that are saved in

Finally, all files serve properly with Jetty6 on the same machine.

There is some nonsense here, so let us clear it out.

First of all, Java classes are compiled binary entities, no source 
there. Sure, there are tools for reverse engineering, decompilers. You 
can make life harder for them by using obfuscators, I believe Jakarta 
has a good one.

Next, for JSPs, well, yes they are source, but in Struts applications, 
they should have a limited role. Even so, there are JSP precompilers, 
Ant has a task for that. Couple it with an obfuscator and your source is 
unreadable. The only thing that remains are the config files. You could 
theoretically encrypt them, keeping the key inside your code, which will 
get obfuscated, anyway.

Does that satisfy you?

Nix.

malformed HTTP?

[Patricio Keilty]

Hi guys,
i recently tried to migrate my webapps from version 5.5.4 to a brand new 5.5.12
installation, so i just copied original $CATALINA_HOME/conf/server.xml & all
$CATALINA_HOME/webapps to ver 5.5.12 corresponding folders. When i entered the
manager webapp, i started seeing "broken" html, kind of source code view in my
browser window, and also some Response HTTP Header data appended. I first blame
on my FireFox browser, but Mozilla and IE will also show not well formed html,
this made me think tomcat was responding with "malformed" HTTP.
Comparing my old server.xml fine with the one in v5.5.4 binaries, i could see a
difference in  attributes: maxHttpHeaderSize="8192" was not set in
my old config. After adding this attribute value to every Connector boila!, my
browser started showing usual apps list html screen. I cannot conclude this is a
problem with Tomcat Connectors, since i´m no Tomcat expert, just wanted to alert
the list just in case.

Apologises for not providing more detailed info right now, i´m in a hurrybut
i can provide some in case it is needed.

This is my Server Information

Tomcat Version  JVM Version JVM Vendor  OS Name OS Version  
OS Architecture
Apache Tomcat/5.5.121.5.0_04-b05Sun Microsystems Inc.   Windows 2003

Have you changed fileEncoding for the default servlet in conf/web.xml?
If not, try setting it to UTF-8. It controls the encoding used to read
static files and defaults to the platform default.

Re: Any issues with using Access Log Valve in production??

[Tim Funk]

It depends. In a nutshell, it shouldn't be a performance issue. Why? Since 
access log writing occurs after the request has been sent to the client- 
there is no performance penalty with respect to the client. *BUT* if all you 
threads are in use then your clients will have a small wait period. But if 
you are running out of workers - you probably have configuration issues.


On CPU starved devices, it might be handy to not use the access log valve.

What do you mean exactly by "virtual directories"?

If it is something like mapping URL paths to file 
system paths, then you can achieve something with 
Tomcat's

Note that 'path' is not limited to one directory
part, ie /urlPath/plus/more is also possible.

Furthermore, inside the web.xml deployment

invoked for a certain URL pattern. See

JNDI-based c3p0 pool in META-INF/context.xml not releasing resources?

[David Perkowski]

I'm running Tomcat 5.5.12 on Mac OS X and have recently switched from  
using a Hibernate-configured DBCP to using a JNDI-configured/owned  
c3p0 pool. I recognize that this may not necessarily be the correct  
place to ask this question, since the problem may be with c3p0, but  
perhaps other users may recognize these problems because c3p0 is  
commonly used with Tomcat.


The problem I have is that when I redeploy my application, which  
itself contains the c3p0 pool  in a META-INF/context.xml  
file, I eventually reach a point -- after 2 or 3 deploys -- where my  
database (PostgreSQL, as it happens) complains about too many clients  
connecting.


I am confident that Hibernate is not involved because the problems  
begin on redeployment, when the pool tries to acquire and validate  
JDBC connections, before Hibernate is given a connection.


Could this perhaps be a failure of Tomcat to un-initialize the pool  
on undeployment (which I perform in my build file using Tomcat's Ant  
tasks, prior to deployment of the new WAR file)? Or perhaps it is a  
failure of c3p0 to release resources when Tomcat asks it to?


I liked that my deployment cycle didn't have to involve restarting  
Tomcat, and I think I can probably solve this by putting the c3p0  
configuration in  in server.xml, but I really  
like that my WAR file is totally self-contained right now. It deploys  
fine the first time, but subsequent deployments (second or third  
time) produce the problem I have outlined here.


Can anyone offer suggestions, or share experiences that could  
illuminate a path forward?


Thanks very much.

All, 
 
 Surprising no one responded the first time. Looking at the source, I noticed a 
org.apache.catalina.util.ServerInfo class in that does access version 
information but it is local to the server and not available from an MBean. I 
need to access version information over RMI (JSR 160). 
 
 Any suggestions? Should an enhancement request be entered? Does it make sense 
for this kind of information be available from the Service or Server MBean? 
 
 How would you programmatically determine that you were running Tomcat 5.5.9 
versus 5.08 or Tomcat 4.x for instance?  
 
 Any thougts would be helpful? 
 
 Thanks 
 
 Andy Gordon

Subject: Encrypting/Protecting JSP/Struts source code

My company is has developed and is now marketing/selling a line-of-business
TSP/Tomcat application which we sell to corporate customers to runs on their
servers in their intranets.

It's suddenly become clear to my company that when we deploy a WAR on a
customers' site, the source code is completely visible to anyone who has
access to the server's drives, and this is belatedly causing some concern.
Obviously there are clauses in our license that formally protect our
intellectual property and at a corporate level we are relaxed, but my boss
is quite concerned about the delinquent administrator who simply downloads &
walks away with the code.

Is there any way in which the deployed WAR file, and all the files that
explode out of it, can be hidden/encrypted/protected on the server, while
still allowing them to be executed by Tomcat? The app is almost completely
JSP/Struts, there is hardly any HTML at all (if any in fact).
 



There is some nonsense here, so let us clear it out.

First of all, Java classes are compiled binary entities, no source 
there. Sure, there are tools for reverse engineering, decompilers. You 
can make life harder for them by using obfuscators, I believe Jakarta 
has a good one.


Next, for JSPs, well, yes they are source, but in Struts applications, 
they should have a limited role. Even so, there are JSP precompilers, 
Ant has a task for that. Couple it with an obfuscator and your source is 
unreadable. The only thing that remains are the config files. You could 
theoretically encrypt them, keeping the key inside your code, which will 
get obfuscated, anyway.


Does that satisfy you?

Nix.

Have you changed fileEncoding for the default servlet in conf/web.xml?
If not, try setting it to UTF-8. It controls the encoding used to read
static files and defaults to the platform default.

RE: Dynamic Datasource Configuration - JNDI read only context

[Rob Gregory]

Thanks David,

I appreciate you confirming the read-only status of the Tomcat context. 

Is there a reason for this being readonly as I ideally need to bind
The dynamic source to the standard context (i.e. literally replace any
defined within the context.xml file) as the datasource is used by my own
classes AND xsp's provided by Cocoon and I'm not sure Cocoon can be
configured to obtain connections from the ServletContext. At least I have
something else to 'Google' during my lack of life ;o)

Cheers
Rob

Your results are correct.  The JNDI provided by tomcat is read-only.  
You'll need to put your DataSource object into your own JNDI context or 
store the DataSource in your ServletContext.  Personally I like the idea 
of putting the javax.sql.DataSource object in the ServletContext and 
using it from there as needed.

Re: [OT] 64Bit Java doesn't honour Xmx,Xms settings?

[Leon Rosenberg]

No but i have an update on my case, I'm managing to kill the JVM in 60
seconds, with errors in HotSpot compiler:
#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
#  SIGSEGV (0xb) at pc=0x002a95fbe300, pid=771, tid=1085610352
#
# Java VM: Java HotSpot(TM) 64-Bit Server VM (1.5.0_06-b05 mixed mode)
# Problematic frame:
# V  [libjvm.so+0x4fa300]
#

We tried to run the machine with no-smp kernel, same shit, but need
more time to crash. Now we are making a memtest to ensure that it's
not a hardware problem...

However, does anyone knows about any known problems with 64bit versions?
We have some irregularities,
first we are using jdk1.5_06 for amd64 on xeonem64t machines, but sun
says its ok (there is no other intel / linux jdk available also)

second: other communicating vms, before and after the server in
question, are 32 bit, could it be a problem?

Leon

permgen isn't affected by the normal

-Xms -Xmx

you have to explicitly set the permGen using the proper setting. I forget

Hi,


Did you check if the new parameter (Xms, Xmx)values are registered for 
your service ? (I am not sure how it works on Linux ).
Here is a similar issue but on Windows platform. 
I am working with 64 bit java on Windows 2003 and 64-bit AMD Opteron 
processor with 16 GB RAM.
I am getting OOME due to PermGen space. I set the following parameteres in 
my service.bat file :
JvmXms = 6g  JvmXmx = 6g JvmX = 256mb.
The problem is when I start the tomcat service it is not taking these 
values.  I checked the windows registry 
and these parameter values are not inserted.  Do you have any idea like 
what might be the problem and 
how to fix these issue ? Any help would be greatly appereciated.

(Note: The same application on 32-bit works just fine .)

Thank you,

Sure, but when ps shows virtual memory usage of 34 GB, I assume it's a

strange problem with extra sessions being created

[Klotz Jr, Dennis]

Hello.

This has got to be one of the strangest problems I've ever come across
and I'm running out of ideas. I have two different keystore.ks files.
One causes problems, the other does not. Please read on...

I have configured tomcat to use SSL with a self-signed certificate. One
version of the keystore.ks results in extra http sessions being created
whenever a user connects to our web app. Replace only the keystore.ks
with a different one and everything works as it should - only one http
session is generated.

This is crazy! Why would a keystore.ks make any difference in how many
http sessions get created?

I appreciate any ideas here. 


Sincerely,

-Dennis Klotz

Using google to find others that have encountered this problem produced

provided. 

I'm currently using J-T-C 1.2.15 with Tomcat 5.5.15.  I've tested using 
both apache 1.3.28 and apache 2.0.54 and have found that if the above 
error message occurs it is because mod_jk cannot find the 
workers.properties file.  To solve this place the JkWorkersFile definition 
outside of a  declaration.

Sure, but it only shows that naming is useless, cause
it will be the same codebase as jk is.


I didn't know about that ab command either. That looks pretty useful. 



Huh, 'ab' is something that comes with Apache httpd for
quite some time :)

Hi Mladen,

Thanks for the info. I think unless I can set up virtual directories on the
Tomcat HTTP server, I might be forced into using another webserver and
connector (jk - soon to be jk3 ;)).

I didn't know about that ab command either. That looks pretty useful. 

Thanks mate,

If you don't need a special things from native web server, then using
Tomcat Native will give you much higher performance if you
compare native web server and Tomcat.

Just as an example for ab -n 50 -c xx localhost:// (1k file)
Tomcat + Native: 14600 req/sec
Apache 2.0.54  : 9200 req/sec

What's interesting is that you can replicate that by yourself :)

  But, you can decompile class files.

  If you obfuscate them, then it makes it harder to read through the
code, and if it is hard enough it may be that the hacker will go elsewhere.

  JavaME applications are done this way, more for size than security,
but netbeans can easily use an obfuscator.

If you have only one server, 1 will be faster and easier to maintain
in almost all situations (proxying, even with a fairly optimized
protocol like AJP, is quite expensive).

You will have to use source code obfuscator, i.e. 
http://java-source.net/open-source/obfuscators


But when it comes to struts you'll have to disable from obfuscating 
class names and public methods (at least  Action.execute and ActionForm

Precompiling JSPs IMO doesn' make any good. In theory, JSP has nothing

Re: Encrypting/Protecting JSP/Struts source code

[David Smith]

In the tomcat workflow, JSPs are first compiled to java source code, and 
then compiled a servlet class.  Pre-compiling takes care of this before 
deployment.  I believe there's an Ant task to do this for you.  In the 
end, all the JSPs and java classes are in compiled binary form that's 
harder although not impossible for a less than honorable admin to 
reverse engineer.


One of the benefits to this is there is no delay on the first request to 
a JSP because the server is compiling it.  That's a big plus even if you 
aren't concerned with releasing source code.

Is the JK Connector the definite one to use as a web connector?

[Chris Mooring]

Hi All,

I have just read various configuration documents for jk2 and jk. It seems as
though support for jk2 is no longer available.
Is jk the recommended connector to use now? It seems odd...like I am using a
previous version. 

Also, I'd still love to hear from anyone about my previous question on
whether Tomcat's native HTTP server is a better option than using a setup
such as IIS or Apache and a connector like JK. See my previous e-mail pasted
below;

Thanks,
Chris

Previous question on performance of Tomcat native HTTP server vs Apache/IIS
and connectors.

Hi All,

I am trying to determine which will deliver better performance;
1) Tomcat's Native HTTP server

2) IIS or Apache with JK2 connectors

I have read in one book (Professional Apache Tomcat 5 SE - Chapter 11) the
following info;
"Performance-Tomcat is inherently slower than a Web server. Therefore, it is
better for the
Web server to serve up static content, while Tomcat handles the dynamic
content (JSPs
and Servlets). Passing requests for static HTML pages, images, and style
sheets through a
Servlet container written in Java is not as efficient compared to a Web
server."

However, this book was written in 2004. 

The current documentation regarding Tomcat 5.5.x connectors at
 specifies a
contradictory view;
"When using a single server, the performance when using a native webserver
in front of the Tomcat instance is most of the time significantly worse than
a standalone Tomcat with its default HTTP connector, even if a large part of
the web application is made of static files. If integration with the native
webserver is needed for any reason, an AJP connector will provide faster
performance than proxied HTTP. AJP clustering is the most efficient from the
Tomcat perspective. It is otherwise functionally equivalent to HTTP
clustering."

Any ideas on which provides better performance would be appreciated.

Another point to note is that we require virtual directories for various
reasons. Is it possible to set these up using Tomcat's native HTTP server?
If not, this may force the issue of which architecture we use.

Once again, any help is appreciated.

Regards,
Chris

Read up on servlets and JSPs on the Sun web site (or Google).
Simplisticaly, servlets are the class files that contain compiled Java
code for processing client requests.  Normally, JSPs are turned into

The use of ps and top as a way of determining memory use can be
misleading for processes with many threads. Although not totally
accurate, for a process with more than 5 threads the ps or top value
should be divided by the number of threads to get the actual amount of
memory used.

Also, consider that the ps/top value is all memory used by the process
not just the heap.

Re: Dynamic Datasource Configuration - JNDI read only context

[David Smith]

Your results are correct.  The JNDI provided by tomcat is read-only.  
You'll need to put your DataSource object into your own JNDI context or 
store the DataSource in your ServletContext.  Personally I like the idea 
of putting the javax.sql.DataSource object in the ServletContext and 
using it from there as needed.

The results of this indicate that the Tomcat Initial Context seems to be
'READ-ONLY' ??



Any pointers into what I am doing wrong are greatly appreciated.

RE: Hibernate debugging problem in Tomcat 5.5.12

[Matt Wiseley]

Behrang,

You probably have .jar files for Hibernate that don't contain debug
information. If you want to debug the Hibernate code itself, get a
source code distribution and build it with debugging info (see
documentation for the javac ant tag), or just add the source files to
your IDE.

That said, I find it's usually less confusing to assume that libraries
like Hibernate are working, and focus on my code which is more likely
the culprit of a bug. You can do that by simply "stepping over" the
calls to compiled libraries. :)

Hi all,

When I want to debug my Hibernate 3.1/WebWork 2.1.7 Web app (which is
deployed into Tomcat) with IDEA, when I add Hibernate related classes to
the watches, I cannot inspect them and instead I see a red message
reading: "Debug info unavailable..." Does anybody know what's possibly
causing this?

BTW - I can debug my DAO outside Tomcat with no problem.

Pass objects to an embedded server

Hi,
I have an application that handles an embedded server instance (this
application start, stop and deploy wars on an embedded server).
Everything works fine, but now I need that some objects of the application
that handles tomcat can be acceded from the deployed wars.
There is a way to do that?
 
Thanks, Claudio.

Actually the doc base set is correct still getting the error as directory

LOAD BALANCING IN TOMCAT

Hi

I am using Tomcat as a service. But since requests pile up quite
substantially, I'm exploring a way to do clustering of 4 separate Tomcat
instances, and then do load balancing of the same.

Pls let me know of any inputs on how to do the same.

After a recent update of my Etch (2.6.15-1-amd64-k8-smp )based
workstation I suddenly experience memory problems also: overnight, while
the system does nothing (other than accepting my email) my swap grows
from 0 MB to > 3 GB and the performance of the system is gone (Dual
Opteron with 4 GB RAM). Only a MS derived solution (reboot) helps.
Redeploying my JBoss application also results in a rise of usage of
swap. JBoss refuses to use more than 1 GB, the same for my Eclipse.

No solution, just a me-too post

Which option to choose? Tomcats native HTTP server or IIS/Apache with connectors?

[Chris Mooring]

Hi All,

I am trying to determine which will deliver better performance;
1) Tomcat's Native HTTP server

2) IIS or Apache with JK2 connectors

I have read in one book (Professional Apache Tomcat 5 SE - Chapter 11) the
following info;
"Performance-Tomcat is inherently slower than a Web server. Therefore, it is
better for the
Web server to serve up static content, while Tomcat handles the dynamic
content (JSPs
and Servlets). Passing requests for static HTML pages, images, and style
sheets through a
Servlet container written in Java is not as efficient compared to a Web
server."

However, this book was written in 2004. 

The current documentation regarding Tomcat 5.5.x connectors at
 specifies a
contradictory view;
"When using a single server, the performance when using a native webserver
in front of the Tomcat instance is most of the time significantly worse than
a standalone Tomcat with its default HTTP connector, even if a large part of
the web application is made of static files. If integration with the native
webserver is needed for any reason, an AJP connector will provide faster
performance than proxied HTTP. AJP clustering is the most efficient from the
Tomcat perspective. It is otherwise functionally equivalent to HTTP
clustering."

Any ideas on which provides better performance would be appreciated.

Another point to note is that we require virtual directories for various
reasons. Is it possible to set these up using Tomcat's native HTTP server?
If not, this may force the issue of which architecture we use.

Once again, any help is appreciated.

Regards,
Chris

Re: [OT] 64Bit Java doesn't honour Xmx,Xms settings?

[Leon Rosenberg]

I would doubt it's a leak in our application since it runs since 15
month on 32bit java without having an OutOfMemory ever. The services
are started with following script(s):

more startMessagingAndFlirtContactServiceBundle.sh
#!/bin/bash

PATH=/usr/local/java/bin:$PATH
[ -n "$JACORB" ] || JACORB=/opt/jacorb
LIB_PATH=/opt/datingr4/lib
CP=`find app -name '*.jar' -printf :%p``find $LIB_PATH -follow -name '*.jar*' -p
rintf :%p``find $LIB_PATH -follow -name '*.zip' -printf :%p`
java -Xms512m -Xmx512m -Djacorb.config.dir=conf -Djacorb.home=$JACORB

de.friendscout.datingr4.startups.StartMessagingAndFlirtContactService
Bundle >logs/startlog 2>logs/starterrors &

we have up to 5 similar services running on a 16 gig machine which
should work. The only memory consuming part are the caches, which are
all based on SoftReferences and are guaranteed to be freed by gc
before an outofmemory is thrown. ps shows the processes using 10 gig
of memory and more on a 64bit machine. Never happend neither on 32bit
system nor with 32bit java on 64bit system.

Tomcat 5.5 will not reload exploded applications when a class is recompiled

Hello,
I have the following problem: Tomcat 5.5 will not reload exploded
applications when a class is recompiled. Is there any modification to be
applied to Tomcat. Note that my autodeploy attribute is set to true(host)
and that my reloadable attribute is also set to true(context).
Any clue very welcome,
Julien.

Hi,
How much memory is available on the computer when it throws the
OutOfMemoryError ?

I am sorry to say, but this sounds like a memory leak in your
application, since the gc should collect loose memory, and not use all
of it, unless it needs to. You will get out of memory errors, going
above what's available on your machine, and also going above -Xmx settings.

I have not heard of this as being bug. Does your application run better
on 32bit systems ?
Wich version of java do you use ?

bye,

[OT] 64Bit Java doesn't honour Xmx,Xms settings?

[Leon Rosenberg]

Hi,

sorry for OT, but since there is so much combined Java experience
here, it's the fastest way of getting an answer.

We have problems with 64bit java (on amd/debian64, with16GB real
memory). Regardsless how much memory we allow the vm (via -Xmx, -Xms)
it takes all it can (up to 34gb virtual memory, 16Gb real memory).
Since we have more than one VM running on the machine  (5VMs all below
1Gb ram) we are running in an outofmemory after a day of running.

Is this a bug? Are there any new undocumented switches for proper
memory configuration?

Thanx in advance

regards
Leon
