Classes not being found in app's WEB-INF directory.
Hi,
I am running tomcat4.0.4 as a standalone on Solaris 7. Simple servlets that
don't need any custom built classes run fine within the
$CATALINA_HOME/webapps/esd/WEB-INF/classes directory. However, servlets
that are dependent on other custom classes will not run when all of the
needed classes are found within the
$CATALINA_HOME/webapps/esd/WEB-INF/classes directory, but they do run when
the dependent classes are found within the $CATALINA_HOME/classes directory.
I don't understand. I thought by default it always looks in the
WEB-INF/classes and WEB-INF/lib directories before looking anywhere else for
needed classes.
The fact that it does run is great, but since we have to have the classes in
$CATALINA_HOME/classes the automatic reload function doesn't work. And for
some reason stopping and starting tomcat doesn't reload the classes in
$CATALINA_HOME/classes either. Does anybody have any ideas what I am
missing? I know it has to be something in the configuration, but I don't
know what.
Thanks in advance for the help!!!

I was using the workers.properties that was shipped with tomca (not a wise
thing) but everything worked. But when i modified it to suit my environment,
these errors vanished.

mod_ssl seams to have problems with HTTP 1.1 Hence it forces IE browsers to
use HTTP 1.0. When i did the same for Netscape browsers too in ssl.conf
file, the page content was displayed successfully.

jk_ajp_common.c errors - issues with mod_jk receiving messages from tomcat
Posted by Harippriya Sivapatham <hs...@pingtel.com>.
Hi everyone,
We are using Tomcat 3.2.3 and Apache 2.0.43 on Linux. I downloaded and
installed mod_jk-2.0.43.so and everything seemed to work fine (atleast on
IE).
However, when I looked at the mod_jk log and i saw the following errors:
[Thu Jan 16 12:23:49 2003] [jk_ajp_common.c (681)]: ERROR: can't receive
the response message from tomcat, network problems or tomcat is down.
[Thu Jan 16 12:23:49 2003] [jk_ajp_common.c (1050)]: Error reading reply
from tomcat. Tomcat is down or network problems.
[Thu Jan 16 12:23:49 2003] [jk_ajp_common.c (1187)]: ERROR: Receiving from
tomcat failed, recoverable operation. err=0
What do these errors mean and how can i fix them?
I was tracking down a strange problem and that's when i happened to see the
log. I would be glad if anyone had any insights into this and if the errors
seen in mod_jk were responsible for the problems i am facing:
On our website, we use the following redirection:
User login: /pds/login/login.html -- Works fine
Redirects to: /pds/login/j_security_check -- Works fine
Redirects to: /pds/initialize/initialize.jsp -- Redirects fine
Redirects to: /pds/ui/index.jsp
the last redirect to index.jsp works fine and Apache gives a 200 response.
On IE, the page is loaded fine. But on Netscape, it says the following:
HTTP/1.1 200 Date: Thu, 16 Jan 2003 15:04:24 GMT Server: Apache/2.0.43
(Unix) mod_ssl/2.0.43 OpenSSL/0.9.6b mod_jk/1.2.2 Content-Length: 1371
Last-Modified: Wed, 15 Jan 2003 16:03:10 GMT Keep-Alive: timeout=15, max=96
Connection: Keep-Alive Content-Type: text/html; charset=ISO-8859-1
>From the apache access logs, it appears as though the index.jsp was not

One small note: I am using mod_jk binary i downloaded from the
jakarta-connectors area instead of the one that is available under tomcat's
bin directory. Does is make a difference?
Thanks for your help in advance.

I too made the mistake of putting all of my classes directly under
WEB-INF/classes. Now I would like to put them into a proper package,
but cannot -- CVS knows the directory structure that I have now, and if
I move the classes into a new directory structure (the package directory
structure "com/ptc/appname") then CVS will get all gorked up.
Does anyone have advice for this scenario? Surely I must not be the
first person who needed to rearrange directories for a webapp using CVS...

I had a bunch of problems with that until I packaged the classes and then it had no problem finding the class files. Give that a try.
Hope it helps
