Two JK2 Connector Questions

[Cunningham Emmett]

1. Are the JK2 connector releases decoupled from
Tomcat?


2. When is connector release 2.0.4 expected to be
released?

I'm specifically interested in BUG # 13869.
"mod_jk2 becomes confused when client breaks the
connection" 

http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13869

If this bug needs to be verified I can do that as we
have a repeatable test case.

thanks,

Increase your maxHeap in the JVM instance running

Re: JK2 and IIS 4.0 performance issue

[Cunningham Emmett]

I have been using Tomcat 4 with JK2 connecting to
IIS on Win2K and have had little or no performance
loss when compared to using iPlanet. There is a small
hit when compared to accessing Tomcat directly. But
that is a *small* hit.

One developer I know has also been using XP to support
this configuration and he has not mentioned any
slowness relative to Win2K.

I hope that this information helps guide you,

IIS Redirector confuses responses

[Cunningham Emmett]

Description:
  Occasionally when under heavy load User1 will 
  receive the response associated with the request
  from User2.

  This is VERY rare and Users find this feature
  undesirable.

  This does not happen running Standalone or using the
  iPlanet redirector.

Configuration:
  Running IIS standalone and communicating through
  the IIS redirector. Both IIS and Tomcat run on the
  same Win2K machine running with SP6.

  Tomcat : 4.1.18
  IIS redirector : JK2 Version 2.0.3

I'd really appreciate:
  - any confirmation of sightings elsewhere.
  - any suggestions of how we MIGHT be able to
re-produce this on demand.

This is not a flippant request for help. This bug has
been sited about 6 times in total and I have no idea
how many hours (person months/years) have been spent
trying to re-create this prior to requesting help
on this venue.

with appreciation,

Re: integrating tomcat 4.04 into iplanet 4.1 using nsapi_redirector on linux

[Cunningham Emmett]

Wow. that was long.
Suggestions:
   1. In workers.properties change localhost to the
FQDN (Fully Qualified Domain Name).
   2. Check to see if iPlanet is in fact forwarding
the request to the redirector OR if it is serving the
request itself. Frequently folks make the content
under tomcat available to the iPlanet Web Server via 
a symlink and this obfuscates the matter. Though this
technique is good for delivering static content and
speeding up the overall process by reducing the burden

on the redirector.
 To check if iPlanet is forwarding the request to
the redirector, tail -f iPlanet log/access and
nsapi.log. There should be a collection of activity on
both sides for each request. If you have it on the
iPlanet side but not the redirector side (of iPlanet)
then you have a problem in obj.conf. My experience is
that you have a problem in obj.conf, almost always.

If you have doubts then attach obj.conf to your
response. I'll take a look at it.

Re: tomcat and netscape

[Cunningham Emmett]

I haven't played with apache and IIS. But I do know 
a fair amount about the iPlanet integration.

If you have a more specific question then just forward
it. 
I hope that I can help.

RE: getRemoteHost(): how to get the fully qualified name?

[Cunningham Emmett]

There was an interface that was sorta usable from
a programmatic standpoint. It was closed due to 
abuse. 

There are companies that sell a survey of
the web relative to IP addresses and hostnames.
I think that one of the products that Paul Vixies
company sells has this, or did a few years ago anyway.

Sorry that I can't recall more details. It's been 
a while.

Re: tomcat 4.0.2 & iPlanet Web Server 4.1 sp9

[Cunningham Emmett]

I have been doing a lot of work with Tomcat 3.x 
and the Nsapi redirector. Yes, it works. 

Your problem is probably one of configuration in 
obj.conf. It is VERY sensitive to ordering.

In the default object you need to define ALL of the
items being redirected prior to the default Ns
handler.


Please attach your obj.conf and I will take a look at
it.

And one of the things that I seem to recall from the
documentation is to NOT use localhost, but instead use
the FQDN (Fully Qualified Domain Name).

Re: Problems With POST Method

[Cunningham Emmett]

Just one datapoint. 

I haven't had any problems getting large datafiles
to upload using POST. I've been working with test
files in excess of 50MB. This is on Solaris 6 & 8, 
NT, and Win2K running against Java 1.3.1_03 and 
Tomcat 3.2.1.

Though the most important aspect of this is the 
upload servlet that you are using. I have not tried
Jeffery Hunters against huge datafiles, only single
digit MB sized ones.

Re: configuring tomcat to run behind iPlanet Web Server...

[Cunningham Emmett]

Let me provide a few pointers. 
   
http://developer.iplanet.com/docs/technote/webserver/migratin.html

The short story is to use the NSAPI redirector
and AJP13. Configure the AJP13 Connection handler
in server.xml.

The redirector is typically included in the tomcat
distribution. Though some folks have had a difficult
time with getting it to build on Solaris.

On the iPlanet side it's also fairly easy if you
are doing simple stuff.

Slow upload speeds

[Cunningham Emmett]

This is my first post to this group and I hope that it
makes sense. 

Using either Tomcat 3.2.1 or 3.2.4 and JDK 1.3.1_01
and my own or 
Jason Hunters Upload servlet there is a performance
problem when  
going from an IE client to a Solaris server. 

Versions Used:
JDK 1.3.1_03
IE 5.5
NS 4.7
Win2K SP2
Solaris 8 patch level 108528-14
Tomcat 3.2.1 and 3.2.4
Jason Hunter Upload Servlet (release Jun 12,02)

Other combinations are fine.
IE -> Win2K server is 1MB/sec
NS -> Win2K server is 1.5 MB/sec
NS -> Solaris server is 3.5 MB/sec
IE -> Solaris server is  77 KB/sec

POST headers look like:
 Netscape
POST /DocUpload?name=foo HTTP/1.0
Referer: http://localhost/upload
Connection: Keep-Alive
User-Agent: Mozilla/4.7 [en] (WinNT; U)
