Re: jk2_init() Can't find child xxxx in none of the 1024 scoreboard slots

[Chong Yu Meng]

Almost finished my updated mod_jk2 compilation write-up. Should be on my 
site by today.

You will need the following packages installed (rpm or source):
- automake
- autoconf
- m4
- libtool
(BTW, good company you work for! I use the site quite frequently to 
translate Mandarin to English and vice versa...)

Hi Chong,

Load balancing is just a change in the configuration file that’s all,  I
think it has to have something to do with the compilation, what lib was it
that you were missing? Perhaps that is our problem too.

Hi Tony,

I can't help you with the load balanced configuration because I'm not
using load balancing (yet). I was using the older version of mod_jk2
just fine too. When the rpm file disappeared from the download site, I
had to compile using the latest version, and that is when my problems
started.
From the description of your problem, I would say that something is
wrong either with the file you downloaded (corrupted download?) or your
compilation failed somewhere. The bad thing about jk2's compile is that
it doesn't give you many errors when it fails, and if you don't look too
closely, the failure can be invisible. I spent 2 days compiling and
re-compiling initially, because I was missing a library file (and didn't
even know it).
I'm investigating this on my end too. Has anybody else on this list
tried and succeeded with Tomcat 4.1.29/Apache 2.0.47/mod_jk2/Linux ?

Note when I change the mod_jk2.so to the old version (from tomcat 4.1.24)
   

it
 

does log the "[error] mod_jk child init 1 -2" after the jk_init error
message.  Everything else stays the same the only thing I have changed is
the mod_jk2.so and it works.  But we need to be sure we are using the more
recent version cause we feel that it could be the cause of some of our
problems.

Hi,

I don’t think the problem is on the tomcat side of things, as if I change
the mod_jk2.so back to the old version we have it we are able to connect.
I have looked over the archives and noticed that others have had this
message but for them it was followed by "[error] mod_jk child init 1 -2" I
am not getting this line...
I also cannot access the /jkstatus page which comes form mod_jk does it
   

not?
 

The library compiled find apart from the usual warnings:

The quickest way to do this is,

( assumes testing with http://localhost )

1) copy the /WEB-INF/classes directory from the /examples/WEB-INF/classes
to your directory.
2) Add the html code to call one of the servlets.

If you can call one of the example servlets then you can backtrack and get
ride of the example servlets and JSP and add your own.
If testing on localhost make sure you have workers.properies, property.host
=localhost
AND
make sure the servlet.xml <Context = "localhost"
When that's complete you'll want to clean up the web.xml file also.

I'm having the same problems, Tony. I got mod_jk2 compiled and tried to
setup the connection between Apache 2.0.47 and Tomcat 4.1.29. I get the
missing child (children ? ;)) errors,  but I was able to get the
servlets and JSPs working, though they spit out errors occasionally. Can
you post your jk2.properties and workers2.properties? I'm trying to
update my HOWTO (http://cymulacrum.net/tomcat/tomcat_toc.html) because
it is obviously unusable now.

Hello,



I am hoping someone might be able to help me work out what on earth is

       

going on here, we have just updated tomcat to 4.1.29 and we are having
problems getting the connectors from apache to tomcat to work.  I am
using the connectors from 4.1.29 to compile the mod_jk2.so but every time
I try to start apache with it I get the following (child numbers change
each time):

The connection to tomcat fails, I get a 404 whenever it tries to access

       

the servlets, there are no other errors logged.  On the tomcat side every
time I restart it I get “CoyoteConnector Coyote can't register jmx for
protocol� not sure what that means… but if I use the mod_jk2 from our
old install it can connect to tomcat no problems.
     

Thanks in advance!

Tony
