AW: How t o find if Loadbalancing is happening...

[Michael Remme]

Hi Vinay,

here we are doing loadbalancing across several linux-machines. The check for
the distribution of the loadbalancing, especially session-sticky, we did by
watching the logfiles on each machine, when after and after different users
enterd the main-server.

 Betreff: How t o find if Loadbalancing is happening...


 Hi All,

 How do I find, if mod_jk is doing load balancing properly with sticky
 sessions ???

 I am trying to load balance between one instance of Apache 1.3.20 and a
 single Instance BUT two workers of Tomcat 3.3.
 I configured Ajp12 and Ajp13 workers and also a load balancer worker lb
 which uses ajp12 and ajp13.
 I am running examples context and it works fine, but I am not sure how to
 confirm if load balancing is happening.

RE: Ever increasing heap size with Tomcat 3.2.3 !!!

[Tõnu Põld]

Hi

We have a similar problem with IBM JDK 1.3.0 (JIT enabled).
I suggest to debug the garbage collector (gc) by turning on the -verbosegc
command option. The garbage collecting activity will be written to stderr.

In our case I suspect that it is JVM problem because the output shows that
90% heap is free, but still the OutOfMemoryException occurs sometimes. The
exception occurs when the servlet application tries to allocate big amount
of memory (5Mb). Even if we set the -Xmx128m and -Xms128m the error occurs,
although the output shows that there is 90% (115Mb) free space in heap.

I suspect that the OutOfMemoryError occurs because the heap gets too
fragmented, therefore the gc can't allocate big sequential memory area. This
makes me believe that the heap defragmentation process takes place very
seldom. If big amount of memory is needed then it is allocated from the end
of the heap, but if the heap size grows close to the maximum, then the
exception occurs. Does anybody know if there is a way to force the
defragmentation to occur more frequently?

I have stress tested our application Sun JRE 1.2.2, and the OutOfMemoryError
never occurred.

With IBM JDK we minimized the occurrences of OutOfMemoryError by setting the
-Xms64m and -Xmx128m. In this case the garbage collector keeps the heap size
somewhere between min and max. Example from our log: 86% free
(92324744/107150328). But if we generate too much load then we still get the
OutOfMemoryError. But at the moment our application doesn't get so much
load, so the OutOfMemoryExcpetions are rare.

Would be very thankful if anybody could confirm/explain my suspicions,
Tõnu

 Hello,
 
 Before my manager insists that we switch to JRun,  can any of 
 the Tomcat
 developers help with a problem of an ever increasing heap size of the
 Tomcat java.exe. ??  (We are running Tomcat 3.2.3 and 
 JRE1.3.1. and the
 IIS redirector)
 
 We are running a load test using LoadRunner scripts on some JSP and
 servlets that are running under Tomcat.  The load is not all 
 that heavy
 but the heap size of the Tomcat java.exe process keeps growing and
 growing. We modified the java command line to start with  -Xmx128m to
 allow 128 MB of heap but we still max out after a day or so.   We even
 modified one of our servlets to create a thread that runs  
 Runtime.gc()
 every 30 seconds.   The LoadRunner scripts just keep logging 
 in the same
 5 people via our authentication servlet so you would think memory use
 would level out at some point.
 
 Nothing we do seems to keep the heap size from growing.  
 
 Are there known issues with Tomcat and heap size??
 
 Doing a web search revealed numerous posts with people having similar
 problems so I believe there is a problem.   The standard 
 response these
 people receive is to increase the heap size via -Xmx   But that seems
 like a band-aid rather than a real solution.   That just delays the
 inevitable.
 
 Any insight as to how to keep the Tomcat process from 
 grabbing more and
 more memory would be appreciated.
 
 Thanks,

AW: Ever increasing heap size with Tomcat 3.2.3 !!!

[Ralph Einfeldt]

Remember that the heap is not the only place where memory 
is needed for the sun jdk. 
There is also the stacksize. (-Xss)

I'm not shure if this applies also to the IBM JDK.

Tomcat4 index.html redirection problem - different to 3.2.x

[Richard Conway]

I have recently started using Tomcat 4.0.1 in preference to 3.2.x. I have
noticed a difference in their behaviour which is causing me some problems.

I am using Squid as a web cache. When I access a 'directory' URL, such as
http://myhost/, then Tomcat serves the index.html file it finds in this
directory. In fact I think that Tomcat is indicating a redirection to the
originator.

However, with Tomcat4 if I access the URL http://myhost/ through the Squid
cache then the index.html redirection is not successful - the browser waits
with the hourglass. If I do the same thing with a Tomcat 3.2.1 installation,
through the same Squid cache, then everything works well.

Note that the Tomcat4 http://myhost/ URL works fine if the cache is
bypassed.

There must be some difference between the way Tomcat4 and 3.2.1 are
performing the index.html redirection. Whatever Tomcat4 is doing, it is
confusing the cache.

It's possible I have mis-configured the Squid cache, but then it works OK
with Tomcat 3.2.1 and various other webservers I could lay my hands on.

Can anyone shed any light on this. Any suggestions for a way of debugging.

Thanks,
Richard.

At least in some versions of sybase 
DatabaseMetaData.getColumns() doesn't 
work.

We use the following as a workaround:

select * from 'tablename' where 1  1

and use ResultSetMetaData to find the 
columns. Dirty trick, but works with 
any database we tested (Adabas D, 
Oracle 8i, Sybase ASA, Interbase, 
Cloudscape, Instant DB, Postgres,
MS SQL)

 Subject: Contexts with relative and absolute DocBase?

 Hi,

 how can I use relative and absolute docBase-Context-settings for
 Contexts of the same Host?
 Something like this doesn't work.

 Host name=localhost appBase=webapps debug=0 
   Context docBase=ROOT path=/
   Context docBase=examples path=/examples/
   Context docBase=tomcat-docs path=/tomcat-docs/
   Context docBase=webdav path=/webdav/

So far, these are all relative and should work fine.

   Context docBase=C:\tmp path=/mywebapp reloadable=true/

Windows is notorious for messing up paths -- try c:\\tmp or c:/tmp
as
well.

 /Host

 I don't want to create another host nor put my webapps to the tomcat
 webapps directory but to my
 own directory tree.


The other othing you can do is look in the log files to see what errors
Tomcat is complaining about -- it *might* be something unrelated.  You
can
post the relevant portions of the logs here if needed.

 Thanks, Dieter.

RMI error (SocketException: socket write error) on Tomcat 4.0, NT4/Win2K

[Tee Chee Han]

Hi,

-- Environment --
I am running Tomcat 4.0.1 on NT4 with JDK1.3.0.

-- Error Symptom --
I have a servlet that makes RMI calls to an RMI server process (non EJB) on the 
same machine. It used to work fine on Tomcat 3.2.3 and Tomcat 3.3 but when we 
switched to Tomcat 4.0 it stopped working.

The servlet looks-up the RMI server object successfully but fails as soon as it 
tries to invoke an RMI method with this exception:
java.net.SocketException: Connection aborted by peer: socket write error
[See end of message for full stack trace]

At first we suspected it had to do with the policy file but we have ruled that 
out because we are NOT running with the -security option and the error doesn't 
seem to point to a security or permission problem. It also doesn't seem like a 
CLASSPATH problem because everything else (including the RMI lookup) works fine.

I have scoured the web for a solution but found only an identical question on 
comp.lang.java with no reply.

Is Tomcat 4.0 doing anything different with RMI? Is JNDI or EJB somehow involved 
here by default? We don't use either of these.

Any help would be much appreciated!

RE: Tomcat4 index.html redirection problem - different to 3.2.x

[Richard Conway]

As far as I can tell, Tomcat 3.2.1 *is* doing a redirect.
Two things draw me to this conclusion:

1. The squid log appears to indicate a GET...
---snip---
2001/12/19 10:58:24| The request GET http://cp1105:8080/ is ALLOWED, because
it matched 'all'
2001/12/19 10:58:24| carpSelectParent: CARP Calculating hash for
http://cp1105.vega.co.uk:8080/
2001/12/19 10:58:24| fwdServerClosed: FD 13 http://cp1105.vega.co.uk:8080/
2001/12/19 10:58:24| The request GET
http://cp1105.vega.co.uk:8080/index.html is ALLOWED, because it matched
'all'
2001/12/19 10:58:24| The request GET
http://cp1105.vega.co.uk:8080/tomcat.gif is ALLOWED, because it matched
'all'
2001/12/19 10:58:24| The request GET
http://cp1105.vega.co.uk:8080/tomcat-power.gif is ALLOWED, because it
matched 'all'---snip---

2. The browser address box shows http://cp1105.vega.co.uk:8080/index.html
even though index.html was not explicitly asked for.

Just incase there are any squid experts out there, here is the squid log I
get for the failed Tomcat4 behaviour...
---snip---
2001/12/19 11:13:24| The request GET http://cp1105:8000/ is ALLOWED, because
it matched 'all'
2001/12/19 11:13:24| carpSelectParent: CARP Calculating hash for
http://cp1105.vega.co.uk:8000/
2001/12/19 11:13:24| fwdServerClosed: FD 10 http://cp1105.vega.co.uk:8000/
---snip---

I don't know the difference between FD13 and FD10 but clearly the two
Tomcats are behaving differently.

Richard.

I think FD is just the short cut for file descriptor.

If I'm right the squid log is 'talking' about two 
different file desscriptors.

May be you should have a look with tcpdump what the

Re: Problem in Installing Tomcat 4.0 in Tru64 Unix

[Nikola Milutinovic]

 I'm installing Apache Tomcat 4.0 in Tru64 Unix. I downloaded
 jakarta-tomcat-4.0.1.tar.gz and successfully unpack it. When I execute the
 command ./startup.sh which startup Tomcat, the following messages appeared;
 
 Using
 CLASSPATH:/tomcat/jakarta-tomcat-4.0.1/bin/bootstrap.jar:/usr/opt/java122/li
 b/tools.jar
 Using CATALINA_BASE: /tomcat/jakarta-tomcat4.0.1
 Using CATALINA_HOME: /tomcat/jakarta-tomcat4.0.1
 Using JAVA_HOME: /usr/opt/java122

I had problems with startup script, it wasn't including config conf/server.xml 
directive, but I solved it, eventually.

Check whether Tomcat is running at all: ps -A | grep java, you should see a line 
like this:

/usr/opt/java130/bin/alpha/native_threads/java
 -classpath 
/usr/local/java/tomcat-4.01/bin/bootstrap.jar:/usr/opt/java130/lib/tools.jar
 -Dcatalina.base=/usr/local/java/tomcat-4.01
 -Dcatalina.home=/usr/local/java/tomcat-4.01
 org.apache.catalina.startup.Bootstrap
 -config /usr/local/java/tomcat-4.01/conf/server.xml start

 The problem is after startup the default applications included with Tomcat
 4.0 wasn't available for browsing. When I entered in Netscape
 http://localhost:8080/ the following error appeared:

You can always try telnetting to port 8080 and issuing HTTP commands directly:

--
Mercury:/# telnet localhost 8080
Trying 127.0.0.1...

This is the response you should get:

RE: Tomcat 3.3 vs. 4.0: TELL US NOVICES WHAT IS GOING ON

[Randy Layman]

TC 3.x supports one version of the JSP/Servlet spec and TC 4.x
support a later version.  Due to a number of reasons, the developers decided
to start developing TC 4 from scratch.  TC 3.x was already well under way so
they have a huge head start.

Assuming that web developers (that's us) want to use the new
releases of JSP and servlets, then the support for TC 3.x will wane and
eventually stop with all of the developers moving over to TC 4.  

Really, the Jakarta guys (who do an excellent job, by the way) have
two quality products, each supporting a different version of the JSP/Servlet
specs.  One has just been under development longer.

 What is going on with 3.3 and 4.0?  Are there two camps in 
 Tomcat?  Is 
 there a battle to see which is going to win?  Why is 4.0 an 
 extension of 
 3.2 and what is 3.3 all about?  I need to know what the plans

 is happening,

mod_jk for NT and EAPI

Hi, 

does somebody has compiled mod_jk with EAPI for NT and could share this one

Until now I didn't manage to compile it on my own and I've mod_ssl installed
with Apache1.3.22 (NT) and the start-up states:

...[Wed Dec 19 13:35:23 2001] [warn] Loaded DSO modules/mod_jk.dll uses
plain Apache 1.3 API, this module might crash under
 EAPI! (please recompile it with -DEAPI)...

Thanx

[Catalin]

Hi to all!

I have an problem and I'm running out of time:

I have an jakarta-tomcat-3.3-m4 running as an service on an NT 4.0
server.
1. I want the Jakarta service keep functioning when an user logoff from
NT (now it is stopping).
2. I want to set the timeout of the session to 1 hour or more (now, if
I let any webappication open without doing nothing, after 30 minutes I
loose the server session and all the variables from it).

Thanks 2 all for any suggestion you may have!

No examples with 4.0.1 install on OSX

[Peter Reynolds]

Hello everybody,

Having successfully installed a 3.3 distribution of Tomcat on OSX10.1.1 I
attempted a 4.0.1 install. However whilst the welcome page and manual pages
are successfully displayed by Tomcat at 127.0.0.1:8080 the attempt to view
any of the examples or servlets results in a 'Resource not available' 404
error message.

I've checked the following:
* The examples are in the web-apps directory of Tomcat home.
* I've removed my old TOMCAT_HOME environment variable that pointed to the
3.3 distribution; and added a CATALINA_HOME variable pointed to the home of
4.0.1.
* My JAVA_HOME variable is correctly set.
* Running ./startup.sh appears to be fine. It reports where all the paths
are; and as described above the home page displays correctly.
* All the permissions on the examples directory are correctly set.
* No errors are reported in the log.

Has any one had any success with 4.0.1 on OSX? If so do they know why it
might not be working for me?

Thanks,


Peter

RE: PLEASE HELP: Apache+Tomcat - Virtual hosts + separate VMs

[Larry Isaacs]

There is a little documentation about this, which is found
at the following online locations.

Context configuration:

http://jakarta.apache.org/tomcat/tomcat-3.3-doc/tomcat-ug.html#context_addcust

Apache mod_jk.conf generation:

http://jakarta.apache.org/tomcat/tomcat-3.3-doc/serverxml.html#ApacheConfig

The result is that a virtual host configuration like:

?xml version=1.0 encoding=ISO-8859-1?
Server
Host name=virtual.host.name address=xx.xx.xx.xxx 
Alias name=virtual.host.alias /
Context path=/myapp docBase=webapps/myapp /
/Host
/Server

results in the following in the conf/auto/mod_jk.conf
generated by the ApacheConfig module:

NameVirtualHost xx.xx.xx.xxx
VirtualHost xx.xx.xx.xxx
ServerName virtual.host.name
ServerAlias virtual.host.alias 

JkMount /myapp ajp13
JkMount /myapp/* ajp13
/VirtualHost

When a request comes into Apache for this virtual host,
mod_jk will include the ServerName, virtual.host.name,
in the forwarded request.  On the Tomcat 3.3 side, this
server name is used in the mapping so that the request
will only map against contexts defined for that virtual
host.  What I don't know is how the ServerName value
would be used by Tomcat 4.x.  It might have the same
effect for virtual hosts configured in Tomcat 4.x, but
I haven't investigated this yet.

Future connector work is happening in the
jakarta-tomcat-connectors project.  Bill Barker has
added org.apache.ajp.tomcat4.config.ApacheConfig and
others to jakarta-tomcat-connectors/jk/java, so there
will likely be something available in Tomcat 4.0.2
and Tomcat 4.1 when they are released.

Cheers,
Larry

 Unfortunately my knowledge of Tomcat 4.x internals is still fairly

  The desired target is Tomcat 4.X.  The revision of Apache is
  of less issue,
  so for the moment I can install whichever one is best able to
  provide a
  working solution.  Right now, we're running Apache 1.3 and
  JServ with one
  JVM per virtual host.  Each JVM runs under an appropriate 
 UID for that
  virtual host.
 
  Our specific interest is to upgrade the web application
  environment while
  preserving the isolation between virtual hosts.

   I am STILL trying to find out how to configure Apache+Tomcat
   so that EACH virtual host has ITS OWN JVM.  This seems to be
   a fairly common question, but no one seems willing to
   actually answer it.
  
   Ideally we want some means that works well with the perchild
   module, so that not only is each virtual host assigned its
   own privileges under Apache, but each JVM is also restricted
   to the privileges available to that uid.
  
   Thanks!  :-)

[Teinert, Arndt]

Hi,

you can control the session-timeout via the web.xml file:

web-app
...
session-config
  session-timeout10/session-timeout 
/session-config
...
/web-app

this sets session timeout to 10 minutes.

You can also use:
HttpSession.getMaxInactiveInterval();

With the service problem:
Perhaps you have to modify the rights for the user who starts the service.
Perhaps its enough to start the service as an administrator.

Bye

Arndt

 Hi to all!
 
 I have an problem and I'm running out of time:
 
 I have an jakarta-tomcat-3.3-m4 running as an service on an NT 4.0
 server.
 1. I want the Jakarta service keep functioning when an user 
 logoff from
 NT (now it is stopping).
 2. I want to set the timeout of the session to 1 hour or more (now, if
 I let any webappication open without doing nothing, after 30 minutes I
 loose the server session and all the variables from it).

 1. I want the Jakarta service keep functioning when an user 
 logoff from NT (now it is stopping).

Start
-Settings
-Control Panel
-Services
-Jakarta
-Settings (or something like that)
-Run as...

Enter administrator and the admin password.  Then it will run as admin and
continue when you log off.

NOTE: If the admin password is changed the services will not start until the
password is changed as above to match.  This is because NT doesn't really
have suid root.

Hi,

you can control the session-timeout via the web.xml file:

web-app
...
session-config
  session-timeout10/session-timeout 
/session-config
...
/web-app

this sets session timeout to 10 minutes.

You can also use:
HttpSession.getMaxInactiveInterval();

With the service problem:
Perhaps you have to modify the rights for the user who starts the service.
Perhaps its enough to start the service as an administrator.

Bye

Arndt

RE: mod_jk for NT and EAPI

[Diego Castillo]

I do not get a warning myself, Apache refuses to start-up without mod_webapp
being compiled with the -DEAPI option. I am currently using mod_proxy as a
workaround, but I would rather use mod_webapp if I could find a version
compatible with mod_ssl.

Did you encounter any problems working with this warning ? Sometimes I get

Until now I didn't manage to compile it on my own and I've mod_ssl installed

RE: JNDIRealm and Interbase - step 3

[Michael Weissenbacher]

you must be sure that interserver is started and responding (try telnet
localhost 3060 to test it). interserver is the server-side part of
interclient.
i'm afraid i've never used interbase with JDBCRealm so i cannot give you
advice for that

  beware of interclient 2.0, it has some serious memory leak. i advice you
 to
  you firebird 1.0.0 rc1 instead of interbase6 open source, it has fixed
 many
  bugs of the original borland open source version. look at
  http://firebird.sourceforge.net/ where you can also get interclient 2.01

Tomcat 3.3 Testimonial

[Mauricio Nuñez]

Hi!

I want to tell you about my experience!

I finish to migrate from 3.2.4 to 3.3 ( about 2 hours yesterday).

I'm impressionated with its performance. 

My homepage receive 3000 hits per hours, and under 3.2.4 my servlet can't 
work, been replaced for a crontab every 5 min generating a static index.html.

Now, with 3.3, my homepage'servlet work without problems! 
It's incredible!

I'm using Linux Redhat 7.1, Blackdown java + ShudoJIT ( OpenJit don't work 
well with virtual host) , green threads (!) , as volano report suggest. 
Web Server : Apache + Mod_JK (Ajp13) + Tomcat 3.3
Others : Freemarker, Thin Oracle JDBC.

My Server is a pentium III dual  800 Mhz and 1GB Ram, and only Java Blackdown 
with green theads had work.

Sun HotSpot, JRockit 3.0 and IBM JDK fail! I guess that's its for the JDK Bug 
refered to Blocking IO.

Blackdown it's very stable, but yesterday i get a Signal 11, and Tomcat 
died. I'm investigating , but that don't repeat until now. And it's a very 
low cost!

That it's all!

RE: VERY VERY URGENT!!!!

I would suggest that you read the mailing list archives, since this
is a common problem with an easy solution (even though those presented so
far are not correct).  Hint, it involves editing the wrapper.properties file
to include the command line switch that Sun provides to avoid this feature
from JDK 1.3.0.

 Hi,
 
 you can control the session-timeout via the web.xml file:
 
 web-app
 ...
 session-config
   session-timeout10/session-timeout 
 /session-config
 ...
 /web-app
 
 this sets session timeout to 10 minutes.
 
 You can also use:
 HttpSession.getMaxInactiveInterval();
 
 With the service problem:
 Perhaps you have to modify the rights for the user who starts 
 the service.
 Perhaps its enough to start the service as an administrator.

Hello everybody,

Having successfully installed a 3.3 distribution of Tomcat on OSX10.1.1 I
attempted a 4.0.1 install. However whilst the welcome page and manual pages
are successfully displayed by Tomcat at 127.0.0.1:8080 the attempt to view
any of the examples or servlets results in a 'Resource not available' 404
error message.

I've checked the following:
* The examples are in the web-apps directory of Tomcat home.
* I've removed my old TOMCAT_HOME environment variable that pointed to the
3.3 distribution; and added a CATALINA_HOME variable pointed to the home of
4.0.1.
* My JAVA_HOME variable is correctly set.
* Running ./startup.sh appears to be fine. It reports where all the paths
are; and as described above the home page displays correctly.
* All the permissions on the examples directory are correctly set.
* No errors are reported in the log.

Has any one had any success with 4.0.1 on OSX? If so do they know why it
might not be working for me?

Thanks,

after set up in your servlet (or jsp) the context type eg:

For sybase, it used to be that you have to run a SQL script to load some

We use the following as a workaround:

select * from 'tablename' where 1  1

and use ResultSetMetaData to find the
columns. Dirty trick, but works with
any database we tested (Adabas D,

Re: JNDI resource for connection pooling

[Rich Baldwin]

Amine

Been playing around w/ the same thing as you.  Have you figured it out yet?  I
am a bit baffled by the role of setting the context in server.xml.   Without making
any changes to server.xml, I downloaded and installed poolman and can run the
database client, querying any of my oracle tables.  However in my servlets, I keep
getting a error when attempting to connect: res-ref-name is not bound in this context.
This all worked fine under tomcat 3.2.  Why do I have to define a context in 
server.xml 4.0
and I didn't in server.xml 3.2?  Poolman seems to work fine w/o one.  Anybody got an 
anwser?

Thanks, Rich

 Hi all,

 I have a problem, please can anyone help?

 I'm trying to create an Oracle pooled connection as a JNDI resource.
 I made the required configuration:

 When I register the resource from a program, everything works fine, when I try to 
register the pooled connection thru JNDI I get the following error:
 javax.naming.NamingException: Cannot create resource instance

 the list bindings and related methods give the following:

 Does anybody have a clue?

 Hello everybody,
 
 Having successfully installed a 3.3 distribution of Tomcat on OSX10.1.1 I
 attempted a 4.0.1 install. However whilst the welcome page and manual
 pages
 are successfully displayed by Tomcat at 127.0.0.1:8080 the attempt to view
 any of the examples or servlets results in a 'Resource not available' 404
 error message.
 
 I've checked the following:
 * The examples are in the web-apps directory of Tomcat home.
 * I've removed my old TOMCAT_HOME environment variable that pointed to the
 3.3 distribution; and added a CATALINA_HOME variable pointed to the home
 of
 4.0.1.
 * My JAVA_HOME variable is correctly set.
 * Running ./startup.sh appears to be fine. It reports where all the paths
 are; and as described above the home page displays correctly.
 * All the permissions on the examples directory are correctly set.
 * No errors are reported in the log.
 
 Has any one had any success with 4.0.1 on OSX? If so do they know why it
 might not be working for me?
 
 Thanks,

These files are actually being displayed in a window with javascript.   The
filename is passed to a javascript function when a button is clicked.   The
script loads the file into a window.   I was unable to successfully load the
files without actually locating them under my web app directory.   I should
be able to create a solution if I had some ideas of what functions/classes
to use.

It goes in the server.xml file in your connector section.

i.e.

I use the -mx extention, but I believe you can use the -Xms and get the

Why don't you put it in the web.xml

RE: How to Increasing Tomcat memory?

[Randy Layman]

You need to put the -Xms (for minimum Java Heap memory) and -Xmx
(for maximum Java Heap memory) where ever you start up Tomcat.  You can hard
code it into the tomcat.bat/tomcat.sh/wrapper.properties file as
appropriate, or you can set environment variable TOMCAT_OPTS (for TC 3.x) or
CATALINA_OPTS (for TC 4.x).

Embedded class doesnot deploy the .war files dynamically. You have to
add
contexts to the embedded tomcat manually.

I was having the same trouble initially until i started debugging and
realised that there are some configuration issues that also cause other
problems.
The regular Bootstrap class which starts up Tomcat loads the classes for
you, however you need to work that out too when you are using the
Embedded
class.

Subject: Embedding Tomcat 4


Hello everyone.

I am trying to embed Tomcat 4.01 in my application. I use the
org.apache.catalina.startup.Embedded class. I simply copied code from
the main method, as indicated in the documentation.

My question is regarding contexts. Why do I have to create the contexts
manually? Can't I have all directories inside webapps be mapped to
contexts automatically? Why are the .war files not decompressed
automatically anymore? If I can't have the contexts created
automatically, how can I process the .war files?

Should I try to start Tomcat by using
org.apache.catalina.startup.Bootstratp class main method instead?

Thanks.

AFAIK tomcat 3.x didn't do a HTTP redirect but served

Why that confuses your squid in not clear to me.
Your description sounds as if the squid doesn't
forward the redirect response to the browser.

 Betreff: Tomcat4 index.html redirection problem - different to 3.2.x
 
 
 
 I have recently started using Tomcat 4.0.1 in preference to 
 3.2.x. I have
 noticed a difference in their behaviour which is causing me 
 some problems.
 
 I am using Squid as a web cache. When I access a 'directory' 
 URL, such as
 http://myhost/, then Tomcat serves the index.html file it 
 finds in this
 directory. In fact I think that Tomcat is indicating a 
 redirection to the
 originator.
 
 However, with Tomcat4 if I access the URL http://myhost/ 
 through the Squid
 cache then the index.html redirection is not successful - the 
 browser waits
 with the hourglass. If I do the same thing with a Tomcat 
 3.2.1 installation,
 through the same Squid cache, then everything works well.
 
 Note that the Tomcat4 http://myhost/ URL works fine if the cache is
 bypassed.
 
 There must be some difference between the way Tomcat4 and 3.2.1 are
 performing the index.html redirection. Whatever Tomcat4 is 
 doing, it is
 confusing the cache.
 
 It's possible I have mis-configured the Squid cache, but then 
 it works OK
 with Tomcat 3.2.1 and various other webservers I could lay my 
 hands on.
 
 Can anyone shed any light on this. Any suggestions for a way 
 of debugging.
 
 Thanks,
 Richard.

RE: How to Increasing Tomcat memory?

What if I had a few connection-instances running on the same machine on
different ports. If I setup the TOMCAT_OPTS value wouldn't restrict the
entire environment to that heap size, or would each  connection get the
value of the TOMCAT_OPTS value?

 Need some .EDU on this one. Thanks.

You need to put the -Xms (for minimum Java Heap memory) and -Xmx
(for maximum Java Heap memory) where ever you start up Tomcat.  You can hard
code it into the tomcat.bat/tomcat.sh/wrapper.properties file as
appropriate, or you can set environment variable TOMCAT_OPTS (for TC 3.x) or
CATALINA_OPTS (for TC 4.x).

 It goes in the server.xml file in your connector section.

 i.e.

Connector className=xxx.yyy.zzz
   Parameter name=-mx value=256000/

 I use the -mx extention, but I believe you can use the -Xms
 and get the

That was/is not the problem. All other methods we 
use in DatabaseMetaData work. (Like getTables(),
getPrimaryKeys(), getCrossReference() and 
several other methods that wouldn't work
without the stored procedures).

 At least in some versions of sybase
 DatabaseMetaData.getColumns() doesn't
 work.
 
 We use the following as a workaround:
 
 select * from 'tablename' where 1  1
 
 and use ResultSetMetaData to find the

At intervals I get this error (or very similar).  I have previously got rid
of it by removing what I last did!

Last time, it appeared to be caused by calling the first() method on a
ResultSet.  This time I have made several changes and have no idea what the
cause is.

How can I pursue it through my code from the information I have below?

AW: How to Increasing Tomcat memory?

[Ralph Einfeldt]

Depends on how you configured tomcat.

If each port is served by one tomcat, each has its own value, 
because they use different VM's.

If you configured one tomcat to server each port the 
value is shared between the ports (Just one instance of the VM)

You are doing something like  res.getOutputStream().write(data); twice

Tomcat 4, IIS, ISAPI redirector

[Dean H. Saxe]

I have run across an interesting problem with Tomcat4/IIS.  I have written 
a servlet which proxies TIFF images to a user for diaply in a web page.  My 
application works fine as long as I use MSIE to connect directly to Tomcat 
and retrieve the TIFF images from the servlet.  However, when I connect to 
IIS via HTTPS and the image is returned (I know it is from the logs) MSIE 
generates an error that the plugin could not read the data.  Furthermore, 
my logs show the connection from MSIE is established twice, back to back.

This has led me to believe that the connection between IIS and Tomcat 
through the ISAPI filter is possibly causing the inclusion of different 
headers (content-type, perhaps?) or other information in the HTTP response 
header which is causing MSIE to choke on these images.  Has anyone here 
seen similar issues with IIS/Tomcat4/ISAPI redirector?  Is anyone aware of 
any tools which would allow me to sniff and decrypt the returned headers?

Any advice/help I can get is greatly appreciated.

Embedded class doesnot deploy the .war files dynamically. You have to
add
contexts to the embedded tomcat manually.

I was having the same trouble initially until i started debugging and
realised that there are some configuration issues that also cause other
problems.
The regular Bootstrap class which starts up Tomcat loads the classes for
you, however you need to work that out too when you are using the
Embedded
class.

I still have no clean working solution.

for the server.xml stuff, I have no clue why we should put config there. The docs says

pooling class in JNDI. and have this class loaded at tomcat startup. the class works 
fine. I'm working on making it load at startup.
I'll keep you posted when it works.

 This all worked fine under tomcat 3.2.  Why do I have to define a context in

access routines).

Any further ideas?  Mostly I would like to know any way that I can get
enough information to trace the issue myself.

SSL on Tomcat 4.0 with IBM JDK 1.3.0

[Mihai Gheorghiu]

I managed to start Tomcat 4.0.1 on my RH 7.0 box only after I replaced Sun's
JDK 1.3.1 with IBM's JDK 1.3.0.
This also avoids errors in some other packages (I'm experimenting with
Velocity).
So, if I want to have an SSL connection to TC 4.0.1 on IBM JDK 1.3.0, what
do I need to do?
Thank you all.

RE: Illegal State Exception - Further information.

[Larry Isaacs]

The Servlet spec says that you can not call
HttpServletResponse.sendError() once output has been
committed to the browser.  If you do so, you get
the IllegalStateException you are seeing.  With
content already sent, it is too late to do a 
redirection.

Content will automatically be committed once the
buffer becomes full (I think the default is 8K).
If the amount of content written to the buffer
before the error occurs varies, it can cause the
appearance of this error to be variable too.

Increasing the size of the buffer would delay the
automatic committing of content and perhaps
help avoid this error.

Cheers,
Larry

  At intervals I get this error (or very similar).  I have 
  previously got rid of it by removing what I last did!
 
 I have commented out all my recent additions, and the system 
 worked again.
 
 I then uncommented all my comments, one by one, and guess 
 what?  It still
 works.
 
 Anyone got any ideas?

Multiple root context applications

[manjuls]

Hi,
I have an application which deploys in the root context of Tomcat. Now the 
problem is that I want to deploy multiple instances of this application on one 
machine only. 
One way is to run multiple tomcats on different ports. Is there any other 
better way ?
Tomcat 4.x supports different instances. But I am not able to figure out if 
that implies multiple tomcat instances with different server.xml etc can be run 
at the same time !! 
I am not averse to using multiple ports .

Thanks in advance for help.

RE: Multiple root context applications

[Bongiorno.Christian]

I dont' see why you can't just 

org.apache.catalina.startup.Bootstrap.main()
twice

just change the system hash to change the catalina.base and catalina.home ...so


System.getProperties().put(catalina.base,/home/tomcat1);
System.getProperties().put(catalina.home,/home/tomcat1);
// start this in a thread?
org.apache.catalina.startup.Bootstrap.main(new String[] {start});


System.getProperties().put(catalina.base,/home/tomcat2);
System.getProperties().put(catalina.home,/home/tomcat2);
// start this in a thread?
org.apache.catalina.startup.Bootstrap.main(new String[] {start});


not the change in the system properties.

anyone disagree?

Re: Tomcat 4.01 tag renders in wrong place

[RSEQUEIRA]

My theory is that the JSP page buffering with Tomcat 3.2.2 (and I say
Tomcat 3.2.2, since I haven't tried this out with another servlet container
like JRun) is the culprit. The JSP compiler generates the servlet code in
the correct order. But during execution of the servlet, the output from
certain dynamic includes get a little skewed in the buffer.
As info, page buffering is one of JSP's feature. It's introduced in JSP to
overcome HTTP protocol's limitations i.e to retract responses after the
server has started sending them. Since output is being buffered, it's
possible to specify header information at any point in the processing of
the JSP page. Buffered output could also be discarded depending on
conditions on your page.

Thanks,
RS
P.S: Maybe the JSP and TOMCAT architects could shed some light on this.

 Subject:  Tomcat 4.01 tag renders in wrong place

 I have a custom tag that performs an include.  The included content gets
 positioned smack in the middle of a preceding td tag.  The custom tag
 content actually appears in the middle of a word (part of one of the td
 attributes).

 Knowing almost nothing about Tomcat 4, it LOOKS like perhaps some
preceding
 content is buffered, and then the custom tag content is written before
the
 buffered content.  But thats just a wild guess.

 Possibly correct. Turn of the buffering. Try this at the top of your jsp
 page:
 %@ page buffer=0 autoFlush=true %

 I'd be happy to provide more info but I'm not sure exactly what to
provide.

 Any ideas?

Re: RMI error (SocketException: socket write error) on Tomcat 4.0, NT4/Win2K

[RSEQUEIRA]

Turn on logging on the RMI server process:

java  -Djava.rmi.server.logCalls=true -Djava.rmi.server.logLevel=VERBOSE
-Djava.rmi.loader.logLevel=VERBOSE ServerName

where,
java.rmi.server.logCalls=true  - will log all incoming calls and
exceptions
java.rmi.server.logLevel=VERBOSE - will log details of outgoing calls
java.rmi.loader.logLevel=VERBOSE - logs classname and codebase whenever
RMI attempts to load a class as aresult of
unmarshalling an arg.

This could help in debugging.

Thanks.

Subject:  RMI error (SocketException: socket write error) on Tomcat 4.0,
  NT4/Win2K

Hi,

-- Environment --
I am running Tomcat 4.0.1 on NT4 with JDK1.3.0.

-- Error Symptom --
I have a servlet that makes RMI calls to an RMI server process (non EJB) on
the
same machine. It used to work fine on Tomcat 3.2.3 and Tomcat 3.3 but when
we
switched to Tomcat 4.0 it stopped working.

The servlet looks-up the RMI server object successfully but fails as soon
as it
tries to invoke an RMI method with this exception:
java.net.SocketException: Connection aborted by peer: socket write error
[See end of message for full stack trace]

At first we suspected it had to do with the policy file but we have ruled
that
out because we are NOT running with the -security option and the error
doesn't
seem to point to a security or permission problem. It also doesn't seem
like a
CLASSPATH problem because everything else (including the RMI lookup) works
fine.

I have scoured the web for a solution but found only an identical question
on
comp.lang.java with no reply.

Is Tomcat 4.0 doing anything different with RMI? Is JNDI or EJB somehow
involved
here by default? We don't use either of these.

Any help would be much appreciated!

Apache/Catalina Problem:java.lang.IllegalArgumentException: addChild: Child name 'myhostname' is not unique

[Cui, Ping]

Hello folks:

   I ran into an Apache/Catalina problem and need help.

   I was trying to set up Apache 1.3.22 and Catalina 4.0.1. Intitially
everything seemed fine and I could test all
the examples. Then, when I checked Catalina log file
apache_log.2001-12-19.txt and found Catalina kept generating following
messages 
and eventually it filled up the entire disk.

 When I replicated all the related directories (apache, catalina, j2se)
to a different machine, everything worked fine. There were no error message
generated. 

I know it appears to be a problem related to an specific machine.
But I've tried real hard to find any possible reason causing this problem
and had no luck. The machine is a Solaris 5.8 server and I am running Oracle
and other applications on the machine and worked fine. I am using
J2SE java version 1.3.1_01. I applied all required Solaris 5.8 patches.


 Could anyone enlightened me about this problem?

Thanks a lot!!

It almost seems like your include machinery is writing to the main output

Contrary Login Use Case

[Churchjr]

In the standard use case for declarative security:

 1.  The user accesses a page
 2.  Tomcat uses web.xml-based Security Constraints and session data about
authenticated users to determine whether to fulfill the request or redirect
to a login or error page.

This is good.  But let's say a business analyst decides that in her webapp,
every user should see page Foo without logging in.  In addition a button
shall be provided in Foo so that the lowly unauthenticated user can be
authorized to see the page in its full glory, with all the superuser bells
and whistles.  (An example could be how Jive Forums work out of the box.)

In this case, say we are starting at Page A, clicking on a link to some
login servlet/jsp, and after authenticating, refreshing Page A.  This seems
to me like an awkward case for declarative security, but I don't expect
sympathy from this hypothetical business analyst.  So has anyone advice for
how to do this?  TIA.

Using Tomcat 4.0.1 latest release (nightly 12/18/01 build)...

I'm trying to save each user's last request for later review.

I'm capturing the request with a Request Filter (implements Filter).

For example, I store the ServletRequest coming into the filter's doFilter
method.  This is actually an HttpRequestFacade object (i.e.
org.apache.catalina.connector.HttpRequestFacade@21e554).  I've noticed that
this object pointer never changes for a given session (i.e. it remains
21e554 for subsequent requests by the given session).  In addition, if I
retrieve this stored request and execute its getRequestURI method, that
method returns null.  The getUserPrincipal returns null as well.  Both are
non null while the Filter stores the request (while not yet fully
processed).

Is this correct behavior?  Is there a way to store the request such that its
data remains intact even after the request has been fully processed?

Thanks...

Imported classes run, but not under Tomcat

[Gilmore, Phil]

I have a class method that works under a container class, 
but Tomcat returns NoClassDefFound on the imported class method when it's 
called from a servlet (which is nearly identical to the container class) 
inside Tomcat.  I searched the archive before subscribing here, but 
couldn't find any questions on this since Dec 1.
Sorry if this message is lengthy but here goes...

I have a public class (thelper.java) with class method ssiServe.  
This method reads a file, replaces keys with new values and outputs the 
contents to System.err.  I have a test.java that calls the 
thelper.ssiserve() class method and it works well.

I now call thelper from a simple servlet (getimage.java), derived 
from test.java, changing the thelper class's output object from 
System.err to a the servlet's PrintWriter object.  
When I run it from my browser, I get a two stack traces 
(with http error 500, reported by Tomcat). 

The first line of the first (labeled exception) is:
javax.servlet.ServletException: Servlet execution threw an exception

The first line of the second (labeled root cause) is:
java.lang.NoClassDefFoundError: classes/thelper

So it would seem to me that the thelper class cannot be seen by 
tomcat, though it is seen in the JVM otherwise.  I've tried 
everything I know how, though I'm very new to Java and JSP.  I can 
incorporate this class method into the calling class and solve the 
problem, but I wrote it this way because the method will be used by 
quite a few different servlets (10), and I need it to be centralized 
for obvious reasons.

My J2SE is installed in c:\javakit and my J2EE is in c:\javaee.

classpath = 
c:\;d:\;c:\javakit\src.jar;c:\javakit\lib\tools.jar;
c:\javaee\lib\j2ee.jar;c:\progra~1\tomcat4\webapps\sqaa\WEB-INF;

  Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01)
  Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode)


This obviously seems like a problem with my classpath or with pack names and
class locations, but it makes no sense to me that it would work outside of
Tomcat.   I deduce that it's a problem with my tomcat configuration (it
doesn't know to look for it) or there's some cardinal rule that I've
overlooked.  Any other ideas?  I've been up and down the tomcat and apache
docs, finding exactly the same information on configuration everywhere on
the web and in a few books I have (and in the config file comments!).
They're all the same, and my standalone servlets work, so I'm pretty sure I
have those instructions down alright.

same error, with the NoClassDefFoundError reporting the current class I'm

Problems executing Conn Pool example that comes with JSQLConnect

[Rudi Doku]

Greetings,

I'm currently evaluating the JSQLConnect Driver. I downloaded jndi1_2_1.zip 
from the sun site, followed the instructions and installed it in the 
following directory - C:\jdk1.3\jre\lib\ext\jndi.jar; I also added this path 
to my classpath.

My problem is that I get the following exception when I run 
ExampleConnectionPool.java from the command line.

Error:init JNDI  javax.naming.NoInitialContextException: Cannot instantiate 
class: com.sun.jndi.fscontext.RefFSContextFactory [Root exception is java.

Any feedback will be very much appreciated.

RE: Imported classes run, but not under Tomcat

[Kendal L. Montgomery]

Put your compile class file in
c:\progra~1\tomcat4\webapps\sqaa\web-inf\classes\classes\test.java.

Since you used classes as your package name you have to put it in the
classes package.

The WEB-INF\classes directory is a root or just the beginning of where
Tomcat looks for standalone classes (not jarred).

Hope this helps.

Do you have fscontext.jar (eg.
'com.sun.jndi.fscontext.RefFSContextFactory')? That's where
RefFSContextFactory class lives, which seems to be the root of your problem
based on your stacktrace.  As I recall you may also need providerutil.jar.

 Subject: Contrary Login Use Case

 In the standard use case for declarative security:

  1.  The user accesses a page
  2.  Tomcat uses web.xml-based Security Constraints and session data about
 authenticated users to determine whether to fulfill the request or redirect
 to a login or error page.

 This is good.  But let's say a business analyst decides that in her webapp,
 every user should see page Foo without logging in.  In addition a button
 shall be provided in Foo so that the lowly unauthenticated user can be
 authorized to see the page in its full glory, with all the superuser bells
 and whistles.  (An example could be how Jive Forums work out of the box.)

 In this case, say we are starting at Page A, clicking on a link to some
 login servlet/jsp, and after authenticating, refreshing Page A.  This seems
 to me like an awkward case for declarative security, but I don't expect
 sympathy from this hypothetical business analyst.  So has anyone advice for
 how to do this?  TIA.


Here's one approach that should work:

* Make sure that page A is not in the area protected
  by a security constraint (so the unauthenticated user
  can see it).

* Make the link on A point to a url (call it B) that is
  within the protected area.

* Have the servlet or JSP page that B points at do an
  immediate redirect back to A.

* When the user clicks the link, they will be authenticated
  (because B is protected) and immediately transported
  back again to A.

This kind of thing should work for either BASIC or FORM-based
authentication.

You cannot assume that the same request object will be used for every
request -- that's just an artifact of the fact that you are not making
simultaneous requests in your tests.

The basic rule:  it is not legal to reference anything in the
HttpServletRequest that the servlet container gives you after the
service() method of your servlet (and the doFilter() method of all your
Filters) has returned.  Anything you need to save across requests *must*
be stored elsewhere (such as in session attributes).


 Thanks...

Re: AW: Classloader question

I ran into a similar problem today that I can not explain while upgrading to
tomcat 3.3. The JSP we created accesses a bean that uses the oracle 1.2 JDBC
driver, classes12.zip.

I placed the Oracle classes12.zip file in the myapp/WEB-INF/lib directory
and then I got the NoClassDef exception.

I unjar'd the .zip file in the myapp/WEB-INF/lib directory and still got the
NoClassDef exception.

I unjar'd the .zip file in the myapp/WEB-INF/classes directory and it
worked.

Where should the .zip file be placed for inclusion in a bean? I recycled
Tomcat after every attempt.

 Subject: Classloader question
 
 Hi everyone,
 
 trying to make a web application work using Tomcat 4.0.1 I found the
 following behaviour, which I don't quite understand:
 
 my application uses a library called xhive.jar
 
 - putting xhive.jar in [catalina]/common/lib
 This works fine, as expected
 
 
 - putting it in [myapp]/WEB-INF/lib
 Causes a ClassDefNotFoundError. I don't know why this is so, it does not
 seem to conform to the description in class-loader-howto.html. However I
 did
 see someone saying that in that directory, only .class files are added to
 the classpath, not .jars
 (http://www.geocrawler.com/archives/3/193/2000/12/0/4841079/).
 
 
 - putting it in both those places
 Causes a ClassCastException ?? Something seems to go terribly wrong when
 the
 jar is placed in both those directories.
 
 Can anyone explain more about this? I'd like to know exactly how this
 works,
 especially I'd like to know why classes from a jar in my application's
 WEB-INF/lib apparently are not loaded.
 
 
 This has been discussed numerous times in the archives, but the short
 answer is this:  it is fundamental to the way Java class loaders work.
 The key issues:
 
 * A class named a.b.c.Foo loaded from two different
 class loaders is ***not*** the same class, even if the
 bytecodes are identical.  Trying to assign from one to
 the other will give you ClassCastException errors.
 
 * The new operator in Java tries to load the specified
 class from the same classloader that loaded the class
 containing this code.  If the class of that name has
 already been loaded by the other classloader, you
 again get ClassNotFoundException errors.
 
 * Class loader hierarchies can delegate up but not down.
 Thus, it's also easy to have the new operator cause
 ClassNotFoundException errors, even though you know that
 the class is there.
 
 Moral of the story -- you are *always* best off having one and only one
 copy of a class visible to a web application.  There's ways to deal with
 some of these issues, but they get pretty intricate.
 
 Thanks
 Heikki Doeleman

  Subject: Classloader question
  
  Hi everyone,
  
  trying to make a web application work using Tomcat 4.0.1 I found the
  following behaviour, which I don't quite understand:
  
  my application uses a library called xhive.jar
  
  - putting xhive.jar in [catalina]/common/lib
  This works fine, as expected
  
  
  - putting it in [myapp]/WEB-INF/lib
  Causes a ClassDefNotFoundError. I don't know why this is so, it does not
  seem to conform to the description in class-loader-howto.html. However I
  did
  see someone saying that in that directory, only .class files are added to
  the classpath, not .jars
  (http://www.geocrawler.com/archives/3/193/2000/12/0/4841079/).
  
  
  - putting it in both those places
  Causes a ClassCastException ?? Something seems to go terribly wrong when
  the
  jar is placed in both those directories.
  
  Can anyone explain more about this? I'd like to know exactly how this
  works,
  especially I'd like to know why classes from a jar in my application's
  WEB-INF/lib apparently are not loaded.
  
  
  This has been discussed numerous times in the archives, but the short
  answer is this:  it is fundamental to the way Java class loaders work.
  The key issues:
  
  * A class named a.b.c.Foo loaded from two different
  class loaders is ***not*** the same class, even if the
  bytecodes are identical.  Trying to assign from one to
  the other will give you ClassCastException errors.
  
  * The new operator in Java tries to load the specified
  class from the same classloader that loaded the class
  containing this code.  If the class of that name has
  already been loaded by the other classloader, you
  again get ClassNotFoundException errors.
  
  * Class loader hierarchies can delegate up but not down.
  Thus, it's also easy to have the new operator cause
  ClassNotFoundException errors, even though you know that
  the class is there.
  
  Moral of the story -- you are *always* best off having one and only one
  copy of a class visible to a web application.  There's ways to deal with
  some of these issues, but they get pretty intricate.
  
  Thanks
  Heikki Doeleman

 Subject: Re: AW: Classloader question

 I ran into a similar problem today that I can not explain while upgrading to
 tomcat 3.3. The JSP we created accesses a bean that uses the oracle 1.2 JDBC
 driver, classes12.zip.

 I placed the Oracle classes12.zip file in the myapp/WEB-INF/lib directory
 and then I got the NoClassDef exception.


This is the expected behavior.

 I unjar'd the .zip file in the myapp/WEB-INF/lib directory and still got the
 NoClassDef exception.


So is this.

 I unjar'd the .zip file in the myapp/WEB-INF/classes directory and it
 worked.


And this.  As an alternative, if you had put the JDBC driver in a JAR file
in the /WEB-INF/lib directory, it also would have worked.

See the Servlet Specification for more details about where web
applications load classes from (unpacked classes under /WEB-INF/classes or
***JAR FILES*** under /WEB-INF/lib).

 Where should the .zip file be placed for inclusion in a bean? I recycled
 Tomcat after every attempt.

Nowhere.

Servlet containers look for JAR files, not ZIP files.  Why Oracle persists
in shipping their JDBC drivers in ZIP format is a mystery to me -- but the
complaints should go to them.

Re: Tomcat 4.01 tag renders in wrong place

[Bill Pfeiffer]

David,

My architecture is pretty straightforward.  I have a jsp page.  It contains
my tag.  My tag does a RequestDispatcher.inlcude() to another jsp page based
on whether a user is logged in.  Nothing tricky here.

Well, except for the trick of the included content magically appearing in
the wrong spot!

 Bill Big Thanks!!

 Bill I will research into why I have to add this tag to get my

 Bill correctly, but if anyone has a short answer on it, I'd be
curious to know.

 It almost seems like your include machinery is writing to the main output
 stream, as opposed to the buffer owned by the tag.  That seems to explain
the
 circumstances you're seeing.

There were a couple of bug fixes in this area that will show up in Tomcat
4.0.2 shortly (and are also fixed in the HEAD branch, which is what you
get when you download a nightly build).

You should also be aware, in case it matters to your application logic,
that calling PageContext.include() causes the response to be committed
first.  This is due to a requirement that remains in the Javadocs for
PageContext.include() from JSP 1.1 days -- even though that is no longer
the desired behavior, the requirement is still there and still has to be
enforced.

Hi Mark,

This is one of the oddest and hardest to find download of any Sun
product/package I've encountered. To be honest I initially just copied it
from my Forte FJ lib area after giving up trying to find it at Sun a while
back.  

You piqued my interest again since it was such a frustrating experience, so
I tried again. This time I did find it at
http://java.sun.com/products/jndi/index.html#download - look for the
'Download JNDI 1.2.1  More' button which (after the usual license accept
screen) will lead you to another download screen that has an 'FS Context'
download option.  Why Sun made this so hard to find is beyond me.

HELP - URGENT : Stability of Tomcat if compare with JBOSS or JRUN

[Frans Thamura]

Dear All,

I am in a decision to buy a software or use tomcat in real production.. I am
very familiar with tomcat 3.2, but never try 3.3, and tomcat 4 still in
progress (i cannot recommended tomcat 3.3 and 4 because i still cannot
install cocoon 1.8.2, and the cocoon list still not response)..Because our
content management system is run on top of cocoon 1.8.2 and cocoon 2 is not
compatible. :(

I want to create a portal, category: intranet, with staff more than 10.000.
This will become nationally project that handle more than millions people...

The country for implementation is Indonesia. This is not a internet portal,
but will be intranet portal with private B2B marketplace inside it. This
project must run on the Net at April, and the prototype of this B2B using
Tomcat :)

The project will serve approx half of Indonesian citizen ( I think this is
database problem right) and there will be instance problem there...
Indonesia have 250 millions citizen, and there will be 120million citizen,
the database will include all parents and children.

Current System is using Oracle Developer, ORacle Database, and SUN (more
than 20 SUNs was used there)... and there will be more than 24 points of
Frame Relay connection.

I need you question. The category is URGENT.. if you can recommended it
using Tomcat, I will use it.. or may be using JRUN if the answer is not
satified enough.. sorry for this wording. -- I just want to show to the
world that tomcat is good and qualified enough to run in real production --

The final decision is using Java as standard programming, because the
multiplatform of that client environment.

We are JRUN partner, and I want to try tomcatany comment??

Question:
Do you have a try to use tomcat in a production with user more than 1000
concurrent user in one time?

can I use tomcat?

or I must buy a JRUN??? or JBOSS + Tomcat?

Because with this business case, i think tomcat is enough, because the
project is look like data warehousing...

We are studying Weblogic, and has contact Weblogic Singapore.. but I still
interest with tomcat or may be JBoss+tomcat..


Thanks

Re: RMI error (SocketException: socket write error) on Tomcat 4.0, NT4/Win2K

[Tee Chee Han]

I have found the solution. It turns out that RMI fails if Tomcat is installed in 
directory with white spaces. Before my original posting, I had actually seen 
this bug in the tomcat-dev mailing list:
http://www.mail-archive.com/tomcat-dev%40jakarta.apache.org/msg17201.html

But I thought my problem was a different one because the error mentioned in this 
bug report was one of MalformedURL. Out of desperation, I tried re-installing 
Tomcat in a directory without white space and now it works.

In any case, thanks RS.

 This could help in debugging.

 Subject:  RMI error (SocketException: socket write error) on Tomcat 4.0,
   NT4/Win2K
 
 Hi,
 
 -- Environment --
 I am running Tomcat 4.0.1 on NT4 with JDK1.3.0.
 
 -- Error Symptom --
 I have a servlet that makes RMI calls to an RMI server process (non EJB) on
 the
 same machine. It used to work fine on Tomcat 3.2.3 and Tomcat 3.3 but when
 we
 switched to Tomcat 4.0 it stopped working.
 
 The servlet looks-up the RMI server object successfully but fails as soon
 as it
 tries to invoke an RMI method with this exception:
 java.net.SocketException: Connection aborted by peer: socket write error
 [See end of message for full stack trace]
 
 At first we suspected it had to do with the policy file but we have ruled
 that
 out because we are NOT running with the -security option and the error
 doesn't
 seem to point to a security or permission problem. It also doesn't seem
 like a
 CLASSPATH problem because everything else (including the RMI lookup) works
 fine.
 
 I have scoured the web for a solution but found only an identical question
 on
 comp.lang.java with no reply.
 
 Is Tomcat 4.0 doing anything different with RMI? Is JNDI or EJB somehow
 involved
 here by default? We don't use either of these.
 
 Any help would be much appreciated!

Newbee - how does tomcat 3.1 know the names of the jar files to load

[Scott Eade]

Hi,

I have had a brief look at the archives, but I can't find this
particular needle in the haystack.

I am trying to get an servlet up and running at an ISP that
has tomcat 3.1 and I am running into a couple of problems.
(The ISP will soon be upgrading to 4.01 but for now I have
to make do with 3.1).

Apart from the fact that the servlet isn't yet running, I am
noticing something quite odd.  If I restart tomcat with one
of the necessary jar files missing from my WEB-INF/lib
directory I get:

Error loading default servlet
java.lang.IllegalArgumentException: Repository
//WEB-INF/lib/turbine-2.1.jar doesn't exist!

How is it that tomcat knows the name of the jar file rather
than just not finding a particular class?  I actually have the
contents of this particular jar file packaged up in another jar
file (with various patched classes included).  I would have
thought the name of the jar files was irrelevant.

Can someone please give me a clue as to how this is
happening so that I can get back to the real problem of
getting the servlet to work.

Thanks,

Scott
