Hello Andre Warnier,
Thanks for the response.
2) tell us what the platform is (O.S.)
-> it is solaris platform :- uname -a
SunOS 5.10 Generic_141414-10 sun4u sparc SUNW,Sun-Fire-V890
3) if you can, also tell what
exact version of the mod_jk moduile you are using. You should be able
to find this in the message that Apache httpd prints in its error log
when it starts.
->mod_jk/1.2.28
3) in the configuration of Apache httpd, there must be configuration lines
starting with "Jk......". Copy them here.
->LoadModule jk_module modules/mod_jk.so
JkWorkersFile /opt/web/apache/app/conf/workers.properties
JkLogFile /opt/web/apache/app/logs/mod_jk.log
JkLogLevel trace
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardURIEscaped +ForwardURICompatUnparsed
JkRequestLogFormat "%w %V %T"
JkMount /* worker1
4) copy here the full content of the "workers.properties" file (comments
removed)
->workers.tomcat_home=/opt/app/tomcat/5.5.9
workers.java_home=/opt/app/j2sdk1.4.2_02/
worker.list=worker1
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=20209
worker.worker1.socket_keepalive=1
5) in the Tomcat conf/server.xml file, there is a <Connector> element with a
protocol=AJP.
Copy this <Connector> element here.
-> <!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="20209"
enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />
6) if the platform is Unix/Linux, execute the following command and copy the
result here :
apache2ctl -V
->./apachectl -V
Server version: Apache/2.0.59
Server built: Feb 18 2010 09:10:59

-D DEFAULT_LOCKFILE="logs/accept.lock"
-D DEFAULT_ERRORLOG="logs/error_log"
-D AP_TYPES_CONFIG_FILE="conf/mime.types"
-D SERVER_CONFIG_FILE="conf/httpd.conf"
7)
if the platform is Unix/Linux, go to the "bin" directory of Tomcat,
execute the command "version.sh" and copy the result here.
-> Tomcat version is 5.5.9.
Please let me know in case i can provide more information.

Allright, so now we may start getting an idea of the problem.
Maybe the first things to do :
1) do not post files as attachments in this list. Mostly, the server strips
them.
Instead, if we ask you for some text information, do a copy-and-paste, and
paste the content directly in your email to the list.
Also, when you copy contents of files here, please remove the comments, and any
private information such as internet hostnames or passwords.
2) tell us what the platform is (O.S.)
3) if you can, also tell what exact version of the mod_jk moduile you are
using. You should be able to find this in the message that Apache httpd prints
in its error log when it starts.
3) in the configuration of Apache httpd, there must be configuration lines
starting with "Jk......". Copy them here.
4) copy here the full content of the "workers.properties" file (comments
removed)
5) in the Tomcat conf/server.xml file, there is a <Connector> element with a
protocol=AJP.
Copy this <Connector> element here.
6) if the platform is Unix/Linux, execute the following command and copy the
result here :
apache2ctl -V
7) if the platform is Unix/Linux, go to the "bin" directory of Tomcat, execute
the command "version.sh" and copy the result here.
With the above, we will get a much better idea of your configuration, and of
what to ask next.
