Re: Diagnosing Tomcat Hang

[Lintang JP]

have U check your Connector settings, maxAcceptConnection part ? this 
settings describe maximum connection will be accepted by tomcat, if it's 
reached, then tomcat will put the rest connection request in hold, waiting 
for other connection untill they finished. By that time, the tomcat looks 
"hang". 

hope it helps.

Re: Tomcat and the HttpServletRequest Object

So it seems the HTML specification *does* require the parts be sent
in particular (source) order.


Thanks!  I was using the wrong search terms-- 'parameter' instead of 
'control name' and so I never found that.  At which point I assumed the 
specification was silent on the matter and I could do whatever I pleased. :) 
So I stand corrected on the browser behavior part.



But it has nothing to say about what *processing agents* do with 'em.
And if the servlet spec *doesn't* demand that the parts be stored and
made available in that same order...


Assuming enough people can be convinced that this is broken, there's where 
the "fix" needs to be applied.  Until the Servlet specification says that 
the order of request parameters must be preserved, Tomcat is free to do 
whatever it wants with them.


Greg Murray (the Servlet specification lead) has asked for input on what 
we'd all like to see in the next version, so here's a chance to comment:

It's never even occurred to me to expect form variables in any order,
though. For one thing, only "successful" controls are sent at all, so
what arrives is intrinsically somewhat arbitrary, eh?  :-)

As always, YMMV!

Your remark about POJOs being part of the API prompted me to chime in

Maybe HTTP is the transport protocol for a messaging framework that runs 
on top.  I don't know enough about all the different intra-JVM 
mechanisms I've head of CORBA, RMI over IIOP, EJB Remote, XML-RPC, and a 
dozen more related protocols.  Some are too raw or not a framework, some 
cover multiple levels of the same problem.  A more featureful 
Application Server (like JBoss) can already do EJB Local/Remote call 
design patterns out of the box, I don't (think I) need JBoss and 
everything it is.  I suppose what throwing in the air is the question:


Is there a web resource that details each of the common intra-JVM 
communication mechanisms thats in place for their pro's con's, 
everything from memory consumption, runtime speed, security policies, 
programming interface, easy of setting up how to future proof remotable 
API usage so it remains compatible and extensible at the same time.  
Then what contracts does each of these mechanisms provide to the 
applications that use them.


HTTP could be a big part of a push or pull data mechanism or it maybe 
implemented outside of HTTP with raw sockets and another wire protocol, 
in this case it would be a JAR file that sides outside of tomcat itself 
and my application which is running in the same JVM as TC would use it 
independatly of TC.


Your serializing objects idea is a little too raw for my use, I'm 
looking for something with a more reliable contract and wider community 
testing than a roll your own TCPIP stack approach.

pooled JDBC connection.  We are using the apache commons JDBC connection
pool code.  This has been working okay until recently when the volume of

RE: Tomcat and the HttpServletRequest Object

[Jeff Grangier]

Hello Wendy,

Is there anything we can do? I have worked with the MS DNA, .NET, SunOne,
IBM Websphere frameworks and they all behave the same way by ordering the
request parameters (first in first out). I know for sure that I am not the
first one and neither the last one to have trouble with this kind of
behavior using Tomcat. Even if the specification does not contain any
direction on how to properly handle the request, Tomcat expected/ordered
behavior would save hours of work to developers worldwide. I sure hope this
issue is not an Open Source wake up call!

Thanks for all your help,
Jeff

You are depending on arbitrary browser behavior.  As far as I can tell, 
there's nothing preventing me from writing a browser that, say, alphabetizes

the request parameters before sending them to the server.

Yes, most browsers send them in the order they appear in the HTML source, 
but unless/until some statement about request parameter order makes it into 
the relevant specification, you depend on that behavior at your own risk.

This isn't something that can be handled by the container-- even if Tomcat 
stops rearranging the request params, you have no control over the browser 
implementation.

Re: Diagnosing Tomcat Hang

[Radek Wierzbicki]

Hi Kenneth,

the threads below are the actual http-processors - threads that answer
requests and they will always show some socket code.

Some of the processors from your listing have a status 'locked' - they
are waiting for some other objects to release some resource.

Were there any more messages below?

In the thread dump you have to look for deadlocks (listed at the bottom)
and processors that are busy with the code of your web application
(maybe some JDBC code) - check the status of those.

Here is a document from Sun about analyzing java stack traces:

Re: Tomcat and the HttpServletRequest Object

From: "Bhupinder Dhillon" <[EMAIL PROTECTED]>

I have the same bloody problem.  The application is a generic form handler 
that e-mails the form values.  Most (all) of the clients expect the values 
to be in the same order as the form itself.


You are depending on arbitrary browser behavior.  As far as I can tell, 
there's nothing preventing me from writing a browser that, say, alphabetizes 
the request parameters before sending them to the server.


Yes, most browsers send them in the order they appear in the HTML source, 
but unless/until some statement about request parameter order makes it into 
the relevant specification, you depend on that behavior at your own risk.


This isn't something that can be handled by the container-- even if Tomcat 
stops rearranging the request params, you have no control over the browser 
implementation.

DeltaManager: calculation of deltas

[Ryan Heaton]

I'm trying to understand how the DeltaManager determines the deltas of a
session.  From what I could find out by browsing the source code, there is no
way to know whether a session attribute is dirty unless is it "set" again, e.g.
HttpSession.setAttribute(Object obj).  In other words, if the following piece of
servlet code were serviced within the context of a DeltaManager, I could not
expect the Count object to be broadcast to the cluster as a delta:

Count count = (Count) request.getSession().getAttribute("count");
count.value++;

I would have to ensure that the following code were executed in order to
broadcast the "count" attribute as a delta:

request.getSession().setAttribute("count", count);

1. Are my findings correct?
2. If my findings are correct, where is the justification for this logic?  Is
there some specification or other official documentation that acknowledges that
this is acceptable?

Regards,

-Ryan Heaton

NumberFormatException After Logging In To Admin Webapp

[David Litterine-Kaufman]

Hi Tomcat Users:

I've googled for several days with no luck on this one.  I'm not sure if
this is rightly a Tomcat question or a Debian question, so I apologize if
this is the wrong forum.  I'm running Tomcat 4.1, sablevm 1.11.3, and struts
1.1 on Debian Sarge.  Sablevm, Tomcat, struts, and the admin webapp were all
installed from their respective stable Debian packages. 

When I log into the admin webapp, both the top and left frames show up as
HTTP Status 500 and I get the following (abridged) stack trace in the
application log:

2005-08-12 17:18:35 StandardWrapperValve[action]: Allocate exception for

The manager webapp seems to be working fine.  Probably something obvious, as
it always is when I can't find any google info about a problem, but I'm at
my wit's end.  Any help would be appreciated.

RE: Tomcat and the HttpServletRequest Object

[GB Developer]

 
The recognition (and so far, little acceptance) that form fields will not be
sent in a guaranteed order by a browser, and never mind that, because even
if your browser does,  the container doesn't guarantee an order either... is
from "Beginner's Servlets". But maybe I only think that because the vast
majority of my time in servlet/jsp development has not been spent with a
container that has this nice "enhancement". 

If you *output* the fields in a determined order, then it seems clear that
you could also do something like name="<%= index %>_restOfName". Hackish,
brutish and "stupid" as it might seem, to those that have not drunk the
koolaid, I think it (or something like it) is a time-honoured tradition for
most people that already understood this (the aforementioned koolaid
drinkers).  
 
This is almost as good as realizing in late 2005 that "referrer" is not a
reliable header. GAH.

Sorry Radek for the last message.  Okay, I've got a thread dump. I'm not

I'm looking at or knowing what else in the dump I need to examine.
About fifteen lines down is stuff about sockets. I wonder if that's of

  Does this produce a stack trace from Tomcat to Catalina.out or does
the thread trace go to the operating system's standard out? Thanks.

Did you try sending a JVM process a QUIT signal (kill -3)? That will
produce a thread dump on a standart output. Do that when your

Re: Tomcat and the HttpServletRequest Object

[Bhupinder Dhillon]

I have the same bloody problem.  The application is a generic form handler that 
e-mails the form values.  Most (all) of the clients expect the values to be in 
the same order as the form itself.


I question the requirement to improve performance on request parameters.  Vast 
majority of the requests have less than 50 parameters and I fail to see how 
changing a collection would improve performance.  It might improve performance a 
little bit when there's hundreds or thousands of parameters but not when it's 
less than 50.


I noticed that SunOne 6.0 web server had the same problem when they embedded 
Catalina in it.  But they at least fixed the problem in subsequent releases (6.1 
and above) when we complained about it.  It makes you wonder - if Sun can fix 
the problem even though performance requirements on SunOne servers are 
significantly higher than tomcat because they are selling the product for 
profit, why tomcat community would not do the same and make life easier for us 
developers.

Loadbalancer in Tomcat 5.5

Can I use the LoadBalancer webapp to load balance requests to a number
of tomcat server in round-robin fashion?  I know there is an example

what I want.

And how can the load balancer make sure the same session (based on the

RE: Tomcat and the HttpServletRequest Object

Hey Dude,

I was certainly not trying to be arbitrary . . . If Iplanet is more "robust"
in this area don't take it personally. As far as your sour memory in DB
development, please leave me out of it. This was a simple question that
makes a lot of sense when you are building any web applications. If there is
a problem with the specification, then it should be changed to accommodate
the user. Tomcat or any other software of that sort are loaded with
functions/features that sacrifice performance with functionality, this is
what you call "an option".

Even if I were to write this as an enhancement, I can tell you from past
experience it would be rejected out of hand by the committers.

In your particular case, the tool you were using before used something like
a Vector or ArrayList to hold the parameter name/value pairs. Tomcat is
almost certainly using a HashMap of some sort. Any deterministic
implementation is going to be slower than the current random access
implementation. Committers will savage any submission that appears slower
and the person submitting it. No thanks, I'm not going there.

Even if Tomcat were to work in the manner desired, there's nothing that says
that every browser is going to submit the form elements in their order of
definition. You really need to abandon this idea and make your application
more robust.

You remind me of people who do SQL database development. They don't specify
an ORDER BY clause on their statements, but it always came back in the order
they wanted. Then one day, they upgraded versions of the database or the
query optimizer decided to take a different path, and all of a sudden the
results are coming out of order. Much wailing and attempted reporting of
bugs ensues... The truth is in SQL, that if you don't specify an ORDER BY
clause, the database can return the results in any order it likes.

Taking advantage of an implementation specific behavior is natural, but it
can lead (as you have found out) to non-portable code. The final arbiter is
the specification, and if the specification doesn't describe the behavior,
you can't say anything about it.

specify the patterns to accomplish the task, nothing matches and I can access 
any page through the http port.

Here is what I'm using: 

In web.xml:


Automatic SLL Forwarding
/Temp/*
/temp/*
/pictures/*
/resources/*
/admin/*
/web/*
/Operator/*
/operator/*
/soap/*
/webtools/*


  
CONFIDENTIAL
  



In server.xml:

  
  




  
  
  


  

  


Is there a way to specify everything except a directory using some kind of NOT 
operator?

Why won't what I'm using above forward me to the correct https port?

Thanks in advance.

Re: Tomcat and the HttpServletRequest Object

[Wendy Smoak]

From: "Jeff Grangier" <[EMAIL PROTECTED]>

Each Element out the getParameterNames enumeration used to be ordered 
based

on the html form layout posting the data (using iPLanet). But, after the
migration the fields are coming in random order when I try to loop through
the fields dynamically. . .


AFAIK, there's nothing in the HTTP spec that says what order the browser 
must send the parameters in.  Most browsers send them in the order they 
appear in the HTML source... but that's not guaranteed.  And then there's 
nothing in the Servlet spec that says the container must keep them in the 
same order that the browser sent them.


What are you doing that depends on the order of the request params?

RE: Tomcat and the HttpServletRequest Object

[George Sexton]

Even if I were to write this as an enhancement, I can tell you from past
experience it would be rejected out of hand by the committers.

In your particular case, the tool you were using before used something like
a Vector or ArrayList to hold the parameter name/value pairs. Tomcat is
almost certainly using a HashMap of some sort. Any deterministic
implementation is going to be slower than the current random access
implementation. Committers will savage any submission that appears slower
and the person submitting it. No thanks, I'm not going there.

Even if Tomcat were to work in the manner desired, there's nothing that says
that every browser is going to submit the form elements in their order of
definition. You really need to abandon this idea and make your application
more robust.

You remind me of people who do SQL database development. They don't specify
an ORDER BY clause on their statements, but it always came back in the order
they wanted. Then one day, they upgraded versions of the database or the
query optimizer decided to take a different path, and all of a sudden the
results are coming out of order. Much wailing and attempted reporting of
bugs ensues... The truth is in SQL, that if you don't specify an ORDER BY
clause, the database can return the results in any order it likes.

Taking advantage of an implementation specific behavior is natural, but it
can lead (as you have found out) to non-portable code. The final arbiter is
the specification, and if the specification doesn't describe the behavior,
you can't say anything about it.

Hello George,

I will consider it an ehancement if it is not in the specification. Adding a
logical order to the list makes it much easier to manage dynamically.
Otherwize, any programmer will have to create their own proprietary indexing
and ordering logic for it.

Let me know if I can help in this upgrade?

Autodeploy strangeness

[BATCHELOR, SCOTT \(CONTRACTOR\)]

I am getting some strange behavior when trying to autodeploy.

I am running tomcat5.5.7 and the instance has several apps running in it.

The contexts are contained within 
$CATALINA_HOME/conf/Catalina/localhost/whatevercontext.xml

There are several different contexts in this path.

However when a .war file is dropped into the webapps directory sometimes it 
will deploy properly, other times it will delete the war file and the xml 
context associated with it.  This is a dev instance and I have set the 
privilages so our developers can drop war files into the webapps directory so 
that I dont have to be involved everytime.

Has anyone else ran into this?

As far as I recall, the JSSE implementation has an order of preference

Tomcat and the HttpServletRequest Object

[Jeff Grangier]

 

Hello,

 

I have migrated my application from iPlanet to Tomcat 5.5 (latest build as
of today) and getting weird results with the HttpServletRequest object:

 

Each Element out the getParameterNames enumeration used to be ordered based
on the html form layout posting the data (using iPLanet). But, after the
migration the fields are coming in random order when I try to loop through
the fields dynamically. . .

 

Here is a snapshot of the code: 

 

Enumeration paramNames = req.getParameterNames();

 

while(paramNames.hasMoreElements()) 

{

paramName = (String)paramNames.nextElement();

.

.

.

 

Has anyone encountered this issue before? Is there a work around?

 

Thank you in advance for your help,

Jeff

Sorry, I'd love to but it...well...works now. Don't ask me why: tomcat
was acting fairly peculiar by the time I'd thrown everything I could
think of at it...maybe it was that. Then it stopped running both
applications (even the one that worked before), I went rowing for an
hour or two, came back and everything was all fine and well again. :)
Anyway, I thank everyone for the effort.

RE: Listening on multiple ips

[David Erickson]

I know, the problem is this is production environment and im still waiting
for my firewall guy to get back to me on opening those ports up to the
second ip, so really I couldn't have tested it, so I figured the next best
thing would be to run it by the list to see if anyone else had done
something like this.

If I have a hostname (or multiple hostnames) pointing to say the second ip
address, they will still be serviced by the host with the associated ip
address correct?

Re: Cannot compile jsp pages with log4j statements -- Tomcat 5.5.9

[Jon Wingfield]

One major change between the 4.1.x branch and the 5.x.x branch is 
packages in generated servlets. In tc4.1.x all the jsps were in the 
org.apache.jsp package irrespective of the structure of the site.
From 5 onwards the jsp directory structure is also part of the package 
name. So, my guess is agent_report_all_in.jsp is in a different 
directory from the one that fails to compile. It works in 4.1 but needs 
to be imported in 5.x.x.

Hi,

It doesn't really matter if you did the app or not, it's irrelevant to this

Anyway, yes an awful lot has changed between 4.1 and 5.5 including the Jasper

However, I have tested your declaration on 5.5.9 and do not get this error 
therefore I think we can rule out the Jasper compiler.

Have you definately cross-checked the class filename in the

First of all, I am not the one who did this app.

Second, it is the case that the JSP file is called

The question is: Why it runs perfect on Tomcat 4.1.30, and has issues

introduced some

bugs that JasperCompiler on Tomcat 4.1.30 does not have?

It doesn't like the agent_report_all_in_jsp classname.
I'm guessing that's supposed to be the name of the servlet class 
generated from the jsp. Are you sure it's correct? If it is 


then you 

may have to use a String argument instead of a class when 


calling the

Listening on multiple ips

[David Erickson]

Hi I was just wondering what the best way to setup tomcat to listen to
multiple ip addresses is?  I have a box with 1 nic that has 3 ip addresses,
the first address port 80 is in use by apache so I want it to listen on the
2nd and 3rd address.  I also need to have different webapps be loaded for
each of the addresses it is listening on.  From looking at the conf file I
was wondering if I can just create two connectors for each ip address ie:





And then in the engine create two Host elements:

  

  


Would this work?

Thanks,
David

RE: Cannot compile jsp pages with log4j statements -- Tomcat 5.5.9

[Allistair Crossley]

Hi,

It doesn't really matter if you did the app or not, it's irrelevant to this 
conversation and you asked a question.

Anyway, yes an awful lot has changed between 4.1 and 5.5 including the Jasper 
compiler, see the change logs.

However, I have tested your declaration on 5.5.9 and do not get this error 
therefore I think we can rule out the Jasper compiler.

<%!
  static private org.apache.log4j.Logger logger = 
org.apache.log4j.Logger.getLogger(_5_jsp.class);
%>

Have you definately cross-checked the class filename in the 
tomcat_home/work/Catalina/localhost/_/org/apache/jsp location?

Allistair.

RE: Cannot compile jsp pages with log4j statements -- Tomcat 5.5.9

[Gary Zhu]

First of all, I am not the one who did this app.

Second, it is the case that the JSP file is called
"agent_report_all_in.jsp". 

The question is: Why it runs perfect on Tomcat 4.1.30, and has issues
with Tomcat 5.5.9? The JasperCompiler on Tomcat5.5.9 has introduced some
bugs that JasperCompiler on Tomcat 4.1.30 does not have?

Thanks.

I think Jon maybe onto something ... to use

agent_report_all_in.jsp

Is that the case?

RE: Virtual Host Config Question

[Scott Purcell]

Thanks, I guess I will have to play with the configuration. But I am using 
straight Tomcat.

Thanks for all the help, I guess it is not an obvious problem, so I must have 
something stupid going on.

Hi,

Not sure about this one. How are you routing requests to Tomcat? Are you using 
the JK connector with a mapping of /*.do? Do you allow image to be handled by 
Apache/IIS or is Tomcat doing it? 
You may need to ensure your static resource uris like images reference the 
context name, e.g src="/unique/images/pic.gif"

Re: Security Questions Regarding Tomcat

[David Smith]

I don't know -- I can see some value to the root only ports below 1024. 
It prevents non-privileged users from stealing trusted service ports in
a mainframe environment -- not that that's a reality anymore.  The best
way to handle this in a production environment is to use the
commons-daemon project at the Jakarta site.

Re: Cannot compile jsp pages with log4j statements -- Tomcat 5.5.9

[Jon Wingfield]

It doesn't like the agent_report_all_in_jsp classname.
I'm guessing that's supposed to be the name of the servlet class 
generated from the jsp. Are you sure it's correct? If it is then you may 
have to use a String argument instead of a class when calling the Logger 
factory method.

Can you post the JSP directives, and the scriplet that calls log4j?
Also, you have been given a line number 39 .. can you work out which
line this is in the work directory.

Subject: Cannot compile jsp pages with log4j statements -- Tomcat 
5.5.9



Hi all,

I am having difficulties to figure out the solution for this issue. 
Jsp pages with log4j logging statements that worked perfect on Tomcat 
4.1.30 could not compile on Tomcat 5.5.9. I commented out the log4j 
statements for these problematic pages, then, tomcat 5.5.9 could 
compile them.


Except commenting out all the log4j statements for the jsp pages in 
order to run on Tomcat 5.5.9, does anyone have any other solutions?


Below is the JasperException message when attempting to compile JSP 
pages with log4j statements:



org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 39 in the jsp file:

Re: Security Questions Regarding Tomcat

[David Smith]

This sounds really fishy.  Tomcat does not by default have any
connectors configured for port 80.  There must be another service or
you've modified your server.xml somehow.

RE: Problems with context

[Fermin Jimenez Najar]

This is the question (by example)
a) In my computer (where the tomcat is installed)
   1. I call this page who have the
sendRedirect("http://192.168.1.64/activation/secondpage.jsp";)
   http://192.168.1.64/activation/firstpage.jsp

   2. Works fine, in the browser of my machine appears:
http://192.168.1.64/activation/secondpage.jsp

b)But the ERROR happens when i try to access from another computer:
  1. I call this page who have the
sendRedirect("http://192.168.1.64/activation/secondpage.jsp";)
   http://192.168.1.64/activation/firstpage.jsp

2. I get this as URL in the browser:
http://localhost/secondpage.jsp

  and this error:
  "The page is not enabled" (or something like that, without error
number)

Sorry, but that's simply not the case. The Connector definitions in
$CATALINA_HOME/conf/server.xml control what ports (and IPs) Tomcat
is listening on.

I'm not familiar with 'ipfilter', but there should be a way to list
the current rule set (equiv to `iptables -L`) to see what's going on.

FWIW!

RE: Problems with context

[Scott Purcell]

Actually I am getting no errors. Basically some of the images and includes do 
not show up unless I take out the "unique" from the querystring. That is why I 
am confused.

Originally, while building the application, I did not have an entry in the 
"" element. I just used something like this:
http://localhost/unique/welcome.do
and all was good. But when I got my staticIP the other night, and entered the 
 information that is when things got out of wack.

Does that help?

Thanks,
Scott

Can you post the JSP directives, and the scriplet that calls log4j?
Also, you have been given a line number 39 .. can you work out which
line this is in the work directory.

Re: "WEB-INF/lib/myjar.jar doesn't contain file xyz..."

[Brian Cook]

When I get this it is usually either because I miss spelled the library 
I was calling or because the permissions on the jar file are too 
restrictive to allow Tomcat to open it.


i.e. I logged in and transfered the file as root and the tomcat user can 
not read it.  I actually have a script now that I run every time I 
upload new files that changes the owner and group of all the files in 
the webapps dir to the tomcat user and group.



t.n.a. wrote:

Tomcat (5.5) seems reluctant to load a .jar file from the WEB-INF/lib
directory.
Specifically, it seems to load tapestly.jar (as the error is displayed
in a tapestry exception page), but it doesn't seem to want anything to
do with cayenne.jar.
The reported error is that a file in cayenne.jar is missing, which is
plain wrong: when you unzip the .jar, it's there.
Also, I've got another application that also uses cayenne.jar - on the
same tomcat server - and it just works.

Am I missing something here?

Cannot compile jsp pages with log4j statements -- Tomcat 5.5.9

[Gary Zhu]

Hi all, 
 
I am having difficulties to figure out the solution for this issue. Jsp
pages with log4j logging statements that worked perfect on Tomcat 4.1.30
could not compile on Tomcat 5.5.9. I commented out the log4j statements
for these problematic pages, then, tomcat 5.5.9 could compile them.
 
Except commenting out all the log4j statements for the jsp pages in
order to run on Tomcat 5.5.9, does anyone have any other solutions?
 
Below is the JasperException message when attempting to compile JSP
pages with log4j statements:
 
 
org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 39 in the jsp file:

"WEB-INF/lib/myjar.jar doesn't contain file xyz..."

[t.n.a.]

Tomcat (5.5) seems reluctant to load a .jar file from the WEB-INF/lib
directory.
Specifically, it seems to load tapestly.jar (as the error is displayed
in a tapestry exception page), but it doesn't seem to want anything to
do with cayenne.jar.
The reported error is that a file in cayenne.jar is missing, which is
plain wrong: when you unzip the .jar, it's there.
Also, I've got another application that also uses cayenne.jar - on the
same tomcat server - and it just works.

Am I missing something here?

Tia,
Tomislav

RE: Out of memory

You can also get OOME in development by causing restarts by copying class files 
or web.xml files into a running web application with reloadable="true" and 
depending on how good you are at cleaning out your appliacation this leaks 
until such a point you get the OOME usually with PermGen error.

Problems with context

[Fermin Jimenez Najar]

Hi. I just has beginning to use the Tomcat, for programming in JSP.
I have the 5.0 version.

I make a web app that uses, in some jsp's files, the command
"response.sendRedirect".

When i execute the pages locally in my computer, works fine, but, i if try
to
test the pages from another computer, i get an error.

This is the way i was executed the sendRedirect for test in another machine,
and always get an error:
response.sendRedirect("http://localhost:8080/activation/obligatorios.jsp";)
response.sendRedirect("http://192.168.1.137:8080/activation/obligatorios.jsp
")
response.sendRedirect("http://mycomputer:8080/activation/obligatorios.jsp";)
response.sendRedirect("/obligatorios.jsp")
response.sendRedirect("activation/obligatorios.jsp")


I think that could be some context problems because, for make the webapp
structure, i
copied one example webapp that comes with the tomcat, then i deleted and
renamed
those files and directories that i dont use (off course, the web-inf still
exist)

What can i do ? Is there is some file where i must configure the context of
the webapp ?

Thanks !!

Re: Out of memory

[Brian Cook]

You would probably be better served looking at what you can change in 
the app so it does not require so much RAM.  It has been my experience 
that when I get an out of memory error it is because I was forgetting to 
close an object, or calling too many large objects globally, or reading 
in too much data into a result set.


Of all my web apps only one requires the heap size to be raised to the 
512MB limit.  It loads multiple 1MB - 10MB overlays them on one another 
and then dynamically overlays a lot of font specific anti-aliasing text.


Unless the application is doing similarly demanding you would probably 
be better severed by debugging the app to see what is using so much RAM.


If you are making a development error like say forgetting to close an 
object something everyone on the list has done it is always better to 
learn of errors as early as possible so you do not carry it over to 
other apps.


A lesson I have learned the hard way.

You can modify the memory settings for the windows service

Forget about a reinstall. Use regedit and go to

Virtual Host Config Question

[Scott Purcell]

Hello,

I have configured two Hosts in my server.xml for two different sites.

The one I am having issues with is as follows:
 


It actuall works well, but I am running "struts" application and with struts it 
includes the "context" which is "unique".

So behind the scenes, (in the URL) I am getting something like this:

http://www.theuniquepear.com/welcome.do
which is really doing this
http://www.theuniquepear.com/unique/welcome.do

And things of course are getting screwed up. 

Is there a way to get around that. I took off the /unique" under "appBase" but 
then it showed the default Tomcat page.

Anyone been here before?

Thanks
Scott

Re: Security Questions Regarding Tomcat

[Robert V. Coward/CTR/OSAGWI]

Having a similar issue to this with Tomcat 5.
Apparently T5 comes with a port 80 proxy server a special servlet 
container or something. Basically I have ipfilter running and only allow 
access  to port 8080, but if you send a request to 80 tTomcat picks up and 
does some sort of internal redirect to port 8080. According to a netstat 
-a only port 808 is litening, but when I run nmap against it it show 80 
and 8080. I'd like to have ipfileter take block all connections and 
redirect packets bound for port 80 to 8080. Inother words I want to do 
what the T5 server seems to be doing already. Anyone have any ideas? My 
network admin is giving me much grief about allowing port 8080 access to 
the web.

Thanks

...not in Linux and some (all?) Unix variants, anyway.

(FWIW I think this root-only-below-1000 rule is an
ill considered security kludge which has probably
caused more trouble than it has circumvented)

You could redirect port 443 to 8443 (and 80 to 8080)
either in an external firewall/router or in iptables
within your server, then start Tomcat as e.g. tomcat
on its usual ports.

RE: Tomcat 5.5 upgrade + logging problems

[Allistair Crossley]

===
Tomcat 5.5.10 Virtual Host example setup with log4j logging per host
===

I hope this can be of some use to those who are confused about how to add 
logging to Virtual Hosts in Tomcat 5.5 Series since the disappearance of 
FileLogger.

You will need to be able to configure DNS resolution for this example.

In this example I setup 2 Virtual Hosts each with their own web applications. 
Each
host gets its own log.

I cause an exception in one of the Virtual Hosts to show that its logging is 
directed
into its log.

Virtual Host DNS Entries


Create 2 DNS entries to the Tomcat target machine

tomcata.qas.com
tomcatb.qas.com

Tomcat 5.5.10

Download and unzip somewhere.

Virtual Host Web Applications

Create directories for the vhost webapps

catalina_home/webapps-a
catalina_home/webapps-b

Copy ROOT and jsp-examples directories from catalina_home/webapps into both 
webapps-a and webapps-b

Setup the exception test


Enter webapps-b/jsp-examples
Create file test.jsp and add into it

logging jars


Download and copy log4j1.2.9.jar into catalina_home/common/lib
Download and copy commons-logging.jar into catalina_home/common/lib

Finish and Test
---

That's it. Start Tomcat and go into the logs directory. You should see all the 
new logs created with some default startup information. 

Now browse to 

http://tomcata.qas.com:8080/ (you should get the ROOT tomcat welcome page)
http://tomcatb.qas.com:8080/test.jsp (you should get an exception, check the 
tomcat-b.log

Summary
---

Note that this is virtual host logging, it is not webapp logging. For webapp 
logging you need to configure log4j within the web application itself which is 
another example.

RE: Tomcat 5.5 upgrade + logging problems

[Allistair Crossley]

Hi Robert,

The fact is that followed precisely the instructions do work. I *almost* 
guarantee this because I walked through it just last week with a guy on a 
vanilla Tomcat 5.5.9 install and I deal with Tomcat and logging daily.

The question is, what kind of logging do you want, because there are 2 types. 
The old FileLogger was internal logging mixed with webapp logging. Tomcat 5.5 
aims to decouple itself from a custom logging implementation and uses the 
Commons Logging wrapper to allow developers to customise their logging output 
in a more flexible and powerful way. 

Therefore the developers did not do a *bad thing* as you describe, you are 
simply peeved off that you don't understand the change. That's natural, noone 
likes change, but change is inevitable if we are to do things better. Granted 
that FileLogger was probably easier, but it was not as powerful or flexible. 
And perhaps the logging page is not the most straightforward but it does work 
when followed.

So now, if you want Tomcat core classes logging, i.e internal Tomcat logging, 
then you need to have a log4j.properties file inside tomcat/common/classes and 
*both* the log4j jar *and* commons logging jar in tomcat/common/lib. This 
information in my view is not all that useful unless you're trying to get to 
the nitty gritty of what's happening. More than likely you are more interested 
in per-webapp logging.

If you want logging for a web application in particular, then you need a 
log4j.properties in the webapp's classes folder and log4j jar only in the lib.

History on this list shows us that logging configuration issues like these are 
almost always caused by something the user has misunderstood or done in their 
"customisation" or web application. 

As for the multiple virtual hosts with webapps;

log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost][/yourwebappname]=DEBUG,
 R

You'll recognise localhost is a servername, so perhaps you could try using your 
virtual host name and let us know if that works.

Cheers, Allistair.

Re: Tomcat W3C Access Log

[Tim Funk]

See ...

It can be declared at the host, context, or engine level.

RE: Tomcat W3C Access Log

Hi,

Just use the Access Log Value with the pattern you need. You can see the 
built-in patterns or define your own one.

Check out the docs

http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/valve.html

Cheers, Allistair.

Tomcat 5.0.28 Character Encoding ISO-8859-9

[Onur Kutlu GAGO]

Hi,

I have character set problem with Tomcat 5.0.28! I had
the same problem with WAS6.0 and fixed it by setting 

-Dclient.encoding.override=ISO-8859-9

to the JVM parameters of WAS. 

Is there a setting where I can set the ENCODING?

Hello,

I'm having some trouble configuring secure connections. I have 2 webapps that I

web.xml-files. In both cases I used / as url-pattern.
I have set the transport-guarantuee for /manager to CONFIDENTIAL.

I have set ciphers to (shortened) NULL_SHA and two others with encryption and
authentication.

When I browse the /dspace- and /odin-pages I het authentication and encryption,
while I only would like to have authentication.

Can anyone tell me/help me why I also get encryption in these cases?
 



The answer is simple, with SSL/TLS, there is no other way to guarantee 
integrity of the transport, other than encrypting it. (All right, maybe 
there is, but current implementations of HTTPS work this way). As for 
authentication, it has got nothing to do with either INTEGRAL or 
CONFIDENTIAL transport. It is a separate thing.


Autehntication gives means to establishing the trusted identity of a 
user (checking if the ID given is authentic). It can be done via several 
mechanisms, some of which are:


- HTTP Basic (user/pass in Base64 encoding)
- HTTP Digest (MD5 digest auth)
- HTTP SPNEGO (supported by MS IIS and Apache+mod_auth_krb/mod_spnego)
- Certificate (if a user has a personal certificate, it can be trusted 
to have verified ID).


Nix.

Re: serving japanese file problem

[Hiroshi Iwatani]

Your tomcat isn't running with UTF-8 and/or your platform doesn't use
UTF-8 for file name.

On my Linux Fedora Core 3:
echo $LANG == ja_JP.UTF-8
means text file(including .java) and file name on OS file system
are created with UTF8 encoding.

on our servlet:
String contType = "text/html;charset=UTF-8";
request.setCharacterEncoding("UTF8");
response.setContentType(contType);
//or, response.setCharacterEncoding("UTF8");
out.println(""); //text is a UTF8 String

Forget about a reinstall. Use regedit and go to 

HKEY_LOCAL_MACHINE\SOFTWARE\Apache software Foundation\Procrun
2.0\\Parameters\Java 

and edit the JvmMx and JvmMs settings as your deployment requires.

RE: Out of memory

Hi,

You can modify the memory settings for the windows service also in the 
service.bat file itself. I've been known to uninstall the service, modify the 
bat file and then service install again. I don't like using the binary version 
so that should work for you.

Secondly, OOMEs should be addressed by profiling (discussed lots on this list) 
not by throwing more memory at Tomcat (unless of course you have a valid need 
for all that RAM).

Need to touch config files for DB-connection

[Hallvard Lid]

Hi

I've got a wierd bug on my tomcat-servers - i have one webapp that uses
a different sql-server than the others. I've defined the connection
under conf/catalina/nameofapp.xml. The wierd part is that after
discovering this, i added a timeout to the config the first time i
touched it(thats how i discovered this), and this timeout gets read, i
notice the timechange on the timeout the next day when the app stops
responding. Other than that its like the xml-file(and the db-data) is
unavaliable to the webapp

Do i need to define the db-connection some other place for it to work
without touching?

The system is a w2003+apache+jk+2tomcats

Re: Java 1.4.2_08 and up breaks Jstl

[Christoph Kutzinski]

It would probably help, if you would describe what you did (i.e. what is 
your source code, your environment, tomcat version , etc.) and what does 
mean "the bug happens" (i.e. error messages, stack traces, etc.)


Now we have just the analogue of "My car works on road a but not on road 
b. Do you know what is wrong?"

No I don't.

I have performed a test of my own.

I have installed j2sdk 1.4.2_05 and j2sdk 1.4.2_08 and j2sdk 1.4.2_09.
I have installed these to the /opt directory. I have my JAVA_HOME pointed
to /opt/java.

First I point /opt/java to /opt/j2sdk1.4.2_09 and restart tomcat. The bug
happens again. I then point /opt/java to /opt/j2sdk1.4.2_08. I restart
tomcat and the same bug occures. I then point /opt/j2sdk1.4.2_05 to
/opt/java, restart tomcat and BINGO no bug. Apparently versions java 2 sdk
1.4.2_09 and java 2 sdk 1.4.2_08 cause the bug to occure just as in the
forum thread.

I have tried a different tomcat version but no luck.

Any ideas anybody? Maybe a configuration change that has occured in the
new java versions?

Martyn



Hi,

I'm not convinced by that forum thread.
It's very hard to believe that there is such a severe bug in Java
1.4.2_06 *that isn't fixed yet*

Do you have a link to a Sun Bugparade entry describing the problem?

Goto this address to read about it:

The new versions will break your jstl code and create errors in the log
and create blank pages.

I have tried a new Tomcat version, no luck. I had it running on another
server but that server is running on Java 1.4.2_05.

So just a tip. Dont install Java 1.4.2_08 or higher. It will kill your
application if your using jstl.
