+1 and maybe also everything in $CATALINA_BASE/lib as well, just in case
your Tomcat lib directory has had things added.

If looking for the source(s) of a given class, here's a bash function

function jargrep {
    sdir=`pwd`
    target=$1
    if [[ "$target"x == "x" ]]
    then
    printf "need at least search value, with optional starting dir\n"
    printf "use colon sep'd list for multiple, non-redundant dirs
(eg CLASSPATH)"
    return
    fi
    cdir=`pwd`
    finded=
    if [ "$2"x != "x" ]
    then
    cdir=( $(echo "$2" | sed s/:/\ /g) )
    fi

    for d in ${cdir[@]}; do
    cd $d
    if [[ $JARGREP_DEBUG ]]; then printf "TOPDIR is now: %s\n" $d; fi
 for jlist in `find . -name \*.jar`
 do
     if [[ $JARGREP_DEBUG ]]; then printf "checking %s/%s for
%s\n" $d $jlist $target; fi
     for founds in `jar tf $jlist | grep $1`
     do
        if [[ $JARGREP_DEBUG ]]; then printf "full founds: %s\n"
"$founds"; fi
    printf "Found in %s as %s\n" $jlist ${founds}
     finded=1
     done
 done
    cd ..
    done


    if [ ! $finded ]; then echo "I got nothin' from ${cdir[@]}"; fi
    cd $sdir

}
which takes the class name (e.g. ServletContext) and an optional 
starting dir (default to .) and scans any found jars for anything 
remotely similar.

What is the servlet-api version indicated in the META-INF/MANIFEST.mf file 
contained in the servlet-api.jar. If it is v3.1 (or higher) the 
ServletContext.class should contain the method getCloassLoader()? If it is 2.x, 
it won't.
You might want to check your classpath (checkout Catalina.out to see a dump of 
the classpath) to see if there is another jar that might contain javax.servlet 
classes that get loaded even before servlet-api.jar.

From where is the ServletContext.class loaded? Is it from 
/lib/servlet-api.jar or from another jar-library on the classpath? 
My guess is that you have multiple jars  containing the ServletContext.class 
and not all of these are related to the same servlet-api version and thus not 
supporting the getClassLoader() method.
You might be loading the wrong SevletContext class file.

You are running an APR connector on 8443.

You are also trying to run an NIO connector on port 8443.

If these are on the same interface, they cannot both be started at
once: choose one.

[Siva.Saravanamuthu]

Mark,

Thanks. You waken my frozen concentration. Yes I was able to identify the error 
which is related APR library and I followed the step as per this article

https://www.openkm.com/wiki/index.php/Tomcat_native_libraries

which made port 8443 listen and able to load the URL with the certificate.

Regards,
Siva

Please make sure port 8443 is listing if not try to restart your tomcat once 
and then check the listing, once you get it is listing, please run below 
command to allow 8443 to open outside of your server.

iptables -I INPUT -m tcp -p tcp -s  0.0.0.0/0 --dport 8080 -j ACCEPT

How to check 8443 Is listing,

Netstat -tnap | grep 8443

Subject: Urgent help tomcat 9 and https 8443

Hello Everyone,

I am new to this group and tomcat.

I am having issue with tomcat 9 using port 8443. I configured tomcat 8443  
using CA certificate and my configuration are as follow.




I verified the certificate file using openssl command and certificate working 
fine and there is no issue with the certificate.

#openssl verify dlkopatu001.crt
dlkopatu001.crt

[Siva.Saravanamuthu]

Thanks for the reply.

There is no firewall or selinux and it is not listening that is the problem.  
Not sure where it is failing ?

Subject: Urgent help tomcat 9 and https 8443

Hello Everyone,

I am new to this group and tomcat.

I am having issue with tomcat 9 using port 8443. I configured tomcat 8443  
using CA certificate and my configuration are as follow.




I verified the certificate file using openssl command and certificate working 
fine and there is no issue with the certificate.

#openssl verify dlkopatu001.crt
dlkopatu001.crt: OK


But for unknown reason port 8443 is not listening and because of that I am not 
able to access url using 
https://url:8443<https://urldefense.proofpoint.com/v2/url?u=https-3A__url-3A8443&d=DwMFAg&c=iYwH3J27U_MBSsOvqcb8y8L0YvDEWvwF8fJyvC56xZM&r=skIkIH_QXTEZR3BEt6FeRMjoXQbfmE83b8AyfPxh3nc&m=RtRGesgJFKJSzkQpps0V7Rj-UV6ePw4JttXM-XZRBMY&s=V6hxOfmjky_Qc47PSvHv8wYAdZFW03iL39cyDN_ZRVI&e=>

Please help me to resolve this issue.

Re: URGENT HELP NEEDED: mod_jk loadbalancing issues

[Edmon Begoli]

Each Tomcat machine is running in 512 MB Max.
(We recently increased that to ~850 MB. We are trying not to go up to far to
avoid prolonged garbage collector pauses)

CPU, I/O utilization under heavy loads is not excessive. 80% max usually 60%

Max. thread settings are default.

I was thinking to bump it by 35-50% as well as the backlog.

BTW - What would be the impoact/side effects of increasing the Connectors
max threads and backlog size.

Thanks,
Edmon


_



What is your load average under these circumstance?


Is each of the 10 tomcats on a seperate physical machine?

What are your max thread settings in Tomcat?

Are your tomcat machines CPU bound or I/O bound under full load?

Re: URGENT HELP NEEDED: mod_jk loadbalancing issues

[Alex Turner]

What is your load average under these circumstance?

Is each of the 10 tomcats on a seperate physical machine?

What are your max thread settings in Tomcat?

Are your tomcat machines CPU bound or I/O bound under full load?

Hi,

First of all - thanks Rainer for willing to look into this issue.

Environment description:

Web Server: Apache 2.0.52
mod_jk: 1.2.15
OS: RedHat ES 4.2
App. Server: Tomcat 5.5.15

Cluster topology: 4 webservers with mod_jk doing sticky loadbalancing into
10 tomcats

MOD_JK Configuration: Pretty much basic mod_jk and Tomcat settings for
AJP13

Description of the issue:

Under very heavy loads for our standards (about thousand of concurrent
users)
we start seeing errors (listed at end botton of this e-mail) in the mod_jk
error log.

Our concern is mod_jk behavior on the web server. We closely monitor
apache
and Apache itself is not under heavy stress. However, shortly after we
start
seeing these messages in the mod_jk's error log, web server becomes
unresponsive
and we have to re-start it.

While the web server server is unresponsive we monitor 8009 port - nothing
is going on it.

We monitor Tomcats and they are fine.

As soon as we re-start web servers traffic resumes. Then under heavy loads
things break again

We are planning on increasing the number of max threads on the Tomcats'
AJP connector to imrpove the throughput of the Tomcats.

However, our concern is with the web server side lock ups. It seems that
mod_jk cannot
recover after this oversaturation.

Re: URGENT HELP NEEDED: mod_jk loadbalancing issues

[Rainer Jung]

Hello,

if you would give detailed information about your problems, we could
advise you, whether it is known, and whether it has been fixed in some
version.

The latest release is 1.2.15, we tried to produce a 1.2.16 release, that
but it has now been withdrawn because of a regression bug. Another
release (1.2.17) will be tried next week.
