Help: jk2_init() Can't find child in apache error log

[nyhgan <ny...@yahoo.com>]

 
Hi everyone!
 
My apache2.0.26 + Tomcat5.0.19 integration is almost done. Actually, the servlets and jsp pages are working properly. But there are some error messages in the apache's error log. I am wondering what causes these errors.  Maybe there is some configuration problems in my jk2.properties and workers2.properties. 
 
Below is the error message and the config files I used.

Performance issue

["Bedrijven.nl" <ma...@bedrijven.nl>]

Hello all,

Maybe a rare question but it's very important for us. What's the case:

* I have a development environment running our applications (simple server,
WIN 2000 Server, Tomcat 4.0.24, struts, max memorysize appr. 320 MB)
* I have a production environment running our applications (extended server,
WIN 2000 Server, Tomcat 4.0.24, struts, max memorysize appr. 1 GB, 4
processors)

Now in our applications we have some jsp pages (i.e. searchpages). So what's
my problem. When I reload a page (submit some action the the form/actionbean
of struts) it's faster on our development system than on our production
system. So normally it's should be so that jsp files should be faster on our
production environment because the server is a lot "bigger". On the other
hand the compilation of jsp's is faster (as expected) on the production
environment. Are there some settings in server.xml (or web.xml) that causes
this???

Thx in advanced!

Maarten
