RE: NameNotFoundException: Name [jdbc/weblogin01b] is not bound in this Context. Unable to find [jdbc]
Dan Thank you. Jconsole mbeans pointed me in the right direction. It made me doubt that Tomcat was reading the same server.xml that I was editing. Sure enough when I found that I was not able to change the description of the Resource "UserDatabase" then I knew I was editing the wrong copy of server.xml Netbeans makes a copy of CATALINA_HOME and uses it as CATALINA_BASE. I was editing the one at CATALINA_HOME instead of the copy at CATALINA_BASE. I wish Tomcat had a clear cut separation between CATALINA_HOME and CATALINA_BASE such that they are ALWAYS distinct instead of the current potential for having the same stuff in both.

Anthony,
My relevant line looks like this (all one line of course):
$SU - $TOMCAT_USER -c "${CONFIG_OPTS} ${CAT_PID} ${TOMCAT_INSTANCE}
start" >> $SERVICE_LOG 2>&1
$SU- set to su for non-SELinux, runuser for SELinux
$TOMCAT_USER - Tomcat user
${CONFIG_OPTS} - CATALINA_HOME, CATALINA_BASE, JRE_HOME, etc.
${CAT_PID} - PID, not used in startup
${TOMCAT_INSTANCE} - Tomcat command based on CATALINA_HOME
$SERVICE_LOG - logs the start and stop of the service
I stuff all of the options in a file which is parsed and placed into
${CONFIG_OPTS}. I could probably use setenv.sh, but this way I have a
root-controlled (and versioned) configuration file for my service
configuration.
I use catalina.sh directly, which is buried in the ${TOMCAT_INSTANCE}
variable. This is so I can do start and stop with one command setup.
Based on that and using catalina.sh, your command line should probably
look like:
start() {
echo -n "Starting Tomcat: "
su - $TOMCAT_USER -c "{$CATALINA_HOME}/bin/catalina.sh start"
sleep 2
}
Make sure your permissions in $CATALINA_HOME are correct.
And your su might need to be runuser, depending on whether or not you
use SELinux.
. . . just my two cents

RE: Trying to do LDAPS with Tomcat 7 on windows
I have found where keytool is on the server where java has been installed. What I think I am supposed to do is export a cert from the server running ldap. As I understand the documentation I have found, I should export the certificate with private keys. I have tried windows certmgr and certsrv and don't have an option to export the private keys even when I am logged in as Administrator on the server. Suggestions ?

Re: Tomcat Start script not starting from init.d or rc.local
You can use upstart if you have that, with a .conf file. However unless you
source the profile.d or wherever your environment variables are held do not
use them in an init task!

Re: How to access Sessions outside of class
Yes Chris RMI is a pain in the ass and I have been trying to make a websocket client endpoint now. It however keeps closing and I am not to sure as of why right after the connection is open. http://stackoverflow.com/questions/26636452/tomcat-clientendpoint-websocket-keeps-closing has the code, asked the questions on there and have not gotten any answers. If you could you may look at the code and reply in this email chain why it keeps closing right after it opens. It is straight forward (as of what i know understand) my ignorance was due to being new to tomcat and websockets so sorry for any of that.

Yes right, fortunately I wasn't working on a remote machine. On Debian Wheezy, the following set of commands actually disables the firewall: --- iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X iptables -P INPUT ACCEPT iptables -P OUTPUT ACCEPT iptables -P FORWARD ACCEPT --- Best regards. Hi, Léa- Ideally, I think you'd want to permanently modify the iptables rules to enable traffic over the desired port. Doing so would keep the existing safety measures in place and all of the rules would survive a reboot. However, if you just want to temporarily disable iptables, I believe service iptables stop would do so. Debian Wheezy doesn't use "service", instead it still uses /etc/init.d. Oddly enough, there is no /etc/init.d/iptables script for Debian[1]. We deploy on Debian in most environments and have simply rolled our own iptables script that runs on boot. Nasty. I like service interface available on Red Hat and CentOS. On Debian/Ubuntu, it looks like the ufw package might be helpful. -Terence Permanently disabling iptables would require a little more work as, in my experience, it is typically configured to start when the system is booted. Yes, and it's not really a good idea for production: you want your firewall configured properly instead of in "by any means necessary" mode.

/etc/init.d are not usually run "in the background". Most /etc/init.d
scripts are processed as "root" on boot, so that shouldn't matter.

I'm not sure that's going to work. "man su". On my system, the command
comes first (with a "-c" switch), the username last. You might want to
consider using "sudo" instead of "su".

Don't use rc.local. Use /etc/init.d/[whatever]
Remember that /etc/init.d scripts aren't directly executed at boot:
you have to "ln -s" each script into /etc/rcX.d where X is the
runlevel number into which the machine is booting.
Hope that helps,

So you have a data-collection program (the foo daemon) and an aggregating / reporting program (the webapp).

Grab the Tomcat Websocket client library and write your code to use it for communication. Or use any other Java-based Websocket client library.

Tomcat Start script not starting from init.d or rc.local
I basically need a script to run automatically when I reboot the server.
I have tried the various ways to get it to work in init.d and it's not working.
When I go into init.d and run it manually it works though.
I think it has something to do with the fact that to run the script manually I
am logged in as root, whereas for it to run automatically it has to run in the
background.
I will include the script info in this email and see if you had an idea as to
where the issue is.
So in /etc/init.d, there is a script called Tomcat, here is the "start" portion
of the script. Once again, when I run this manually while logged in as root it
launches.
#!/bin/sh
# Apache Tomcat Startup Script
# chkconfig 234 20 80
JAVA_HOME=/opt/jdk1.6.0_45
CATALINA_HOME=/opt/tomcat
TOMCAT_USER=tomcat
start() {
echo -n "Starting Tomcat: "
su $TOMCAT_USER $CATALINA_HOME/bin/startup.sh
sleep 2
}
I tried creating a new script and putting that one in "rc.local".
Here is the "rc.local" command:
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
su tomcat /opt/tomcat/bin/startup.sh
This is a total rookie issue I am surebut just in case you might be able to
help with an easy enough fix, I would greatly appreciate it. I don't even know
where to look for error logs to troubleshoot this.
Thanks for any assistance.

Sometimes when you get a NameNotFoundException, it's because the pool
encountered an error when it was being created. Hence it doesn't actually
exists. A couple things you can do to troubleshoot.
1.) Set an initial size for your pool. This will force it to make at least
one connection at startup which will generally cause it to fail fast, if
there is a problem. You can then look in the logs to see the error.
2.) Connect with jconsole or jvisualvm and look at the mbeans for Tomcat.
When the pool is actually there, you should see it in the mbeans.

You're using a different factory (specifically Oracle's implementation), so
the configuration attributes are going to be different. Not sure how to
set initial size with this implementation.

NameNotFoundException: Name [jdbc/weblogin01b] is not bound in this Context. Unable to find [jdbc]
Hello
I'm having difficulty getting a JDBC DataSource using Tomcat 8.
I want to define the JDBC details in server.xml so the database identified
depends on the server and not the application. It will be beneficial for me if
the applications only need to know the JDBC name and not password details.
Thus I'm using GlobalNamingResources in server.xml
and ResourceLink in context.xml
I'm obviously not getting it right because I get this exception:
javax.naming.NameNotFoundException: Name [jdbc/weblogin01b] is not bound in
this Context. Unable to find [jdbc].

In CATALINA_BASE/conf/server.xml
I have included a variety of slightly different resources all aiming to get to
the same database schema hopefully one of them will be right:
In META-INF/context.xml
I have a ResourceLink to each resource
In web.xml I made no changes related to JDBC on the understanding that the
ResourceLink elements will be sufficient.
In Java code I try to get a DataSource as follows:
String dbUser = "weblogin01b";
try {
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
// Get data source
ds = (DataSource) envCtx.lookup("jdbc/" + dbUser);
if (ds == null) {
logger.log(Level.WARNING,"Null datasource for " + dbUser);
}
}
I get similar exceptions for each of the names:
jdbc/weblogin01
jdbc/weblogin01b
jdbc/weblogin01c
After years using GlassFish, I'm struggling with Tomcat, any help would be much
appreciated.

Trying to do LDAPS with Tomcat 7 on windows
I am trying to implement an application from a vendor who has deployed it using Tomcat. Due to a client requirement, I need to use LDAPS to talk to their AD Directory service. I have it working on LDAP, so I know the config is correct at that point. Where I am having a problem is figuring out how to import the cert from the CA I have setup on the AD server. Everything I can find mentions commands that aren't on the windows server that Tomcat 7 is installed on. I tried installing the openssl tools that I found but I still don't have the commands to import a cert. Have been looking on Google without any success. Would appreciate any suggestions or links on how to get this working. Thanks, Ron
Re: tomcat websocket communication with external java program
All you need to do is to have your "external java" use a websocket client (like Jetty's http://www.eclipse.org/jetty/documentation/current/jetty-websocket-client-api.html) to connect to your server's websocket endpoint. -- Igor Kolomiets On Sat, Oct 25, 2014 at 3:41 PM, Jason Ricles wrote: > I have a tomcat webpage with a websocket server written in java to > communicate with the webpage.

And as Chris pointed out, JSON is fairly ubiquitous and easy to deal with. RMI could work and is simple enough. There are a few downsides worth considering: 1) it's strictly java-to-java IPC, so no other technologies (e.g. .NET) can participate down the road; 2) it's not firewall friendly -- but that would only matter if there was a fw between foo and bar; 3) it's not hip and cool -- not sure how widely used it is anymore outside of EJB (do people still write EJBs?). Did you say earlier that foo would need to send unsolicited alerts at some point -- i.e. send alerts even when there's no client listening? That could possibly complicate the design in that I believe the ws server endpoint's life begins only in response to a client connection. (I'm thinking of the server endpoint for the browser here.) Thus such alerts would need to go somewhere until a client shows up wanting to see them (e.g. a database). And if that's the case why not send all of them there. Sounds like you may have some design issues to work out and we don't have enough details to be of much help. --tim. > On Tue, Oct 28, 2014 at 6:55 PM, Christopher Schultz < > ch...@christopherschultz.net> wrote: > > > -BEGIN PGP SIGNED MESSAGE- > > Hash: SHA256 > > > > Jason, > > > > On 10/28/14 3:06 PM, Jason Ricles wrote: > > > Chris, foo has to run as a daemon outside of tomcat.

Re: How to access Sessions outside of class
foo is not a webapp, it is a separate program running on the computer as a daemon. It has to do this stuff for it needed to be ran like this. bar is basically the gui to the daemon, providing what is happening on the machine to someone at another computer, since the machine is headless these programs are being ran on. So I am curious as to how having my foo program running outside of bar how it can interact using websockets? So far I have seen that they are disconnected and have no clue about each other outside of using RMI.
