Could not load the Tomcat server configuration - java

I have installed apache tomcat7 using sudo apt get in ubuntu. I have added apache tomcat 7 to eclipse using Windows > Preferences > Server > Runtime Environment.But when I'm starting the server from server view by right clicking the shown Tomcat v7.0 Server at localhost [Stopped,Republish]
It says:
Could not load the Tomcat server configuration at /Servers/Tomcat v7.0
Server at localhost-config. The configuration may be corrupt or
incomplete.
The path to tomcat7 that I've provided is /usr/share/tomcat7

I've just been encountering a very similar issue in Ubuntu while trying to get Eclipse Mars and Tomcat7 integrated because Eclipse was expecting the tomcat configuration files etc to be all in the same location, and with the necessary permissions to be able to change those files.
The following instructions from this blog article helped me in the end:
cd /usr/share/tomcat7
sudo ln -s /var/lib/tomcat7/conf conf
sudo ln -s /var/log/tomcat7 log
sudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy
sudo chmod -R a+rwx /usr/share/tomcat7/conf

I've just solved this exact problem on my Ubuntu 14.04 with Eclipse Mars 2.
This could happen when Eclipse is not finding Tomcat's configuration files where they are expected to be. This place is in
$eclipse_workspace_folder/$version_of_your_tomcat_server_at_localhost/
(by default if you didn't changed server's name). So you have to copy all the files under your $tomcat_installation_folder/conf/* to the workspace server's folder.
But it was easier to just remove the server from your server list and add it again. Eclipse will automatically recreate all these files again into the proper folders. Like in the picture below:
In my case I've downloaded tomcat-8.0.35 from the website, so the configuration files needed are in /opt/apache-tomcat-8.0.35/conf/ filesystem.
Just delete the desired server from the Servers view (Window -> Show View -> Servers) and then go to Window -> Preferences -> Server -> Runtime Environment -> Add and add the server again.

You can install tomcat7 in ~/tomcat7 instead of /usr/share/tomcat7.
Close Eclipse.
Delete org.eclipse.wst.server.core.prefs and org.eclipse.jst.server.tomcat.core.prefs in {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings.
Launch Eclipse.
Go to Window->Show View->Other... and choose the Servers.
Select Tomcat v7.0 Server from the server type and press Next.
Enter /home/user/tomcat7 (not /usr/share/tomcat7) into the "Tomcat installation directory" and press Download.
Wait a few minutes and press Finish.
tomcat7 worked correctly with Eclipse 4.4 on my Ubuntu 15.04 in this way.

I know it's an old question and it has been solved already but for me the Tomcat conf/tomcat-users.xml file was created with a different encoding from the rest of the configuration files. The first line of that file looked like this:
<?xml version='1.0' encoding='cp65001'?>
All I had to do to solve the issue was change that line for:
<?xml version="1.0" encoding="UTF-8"?>
And voila.
I have no idea what 'cp65001' means or why it was created like that.
Maybe this will help other users facing the same issue.

The application is trying to load /usr/share/tomcat7/conf/ which doesn't exist. Eclipse assumes conf is in the same directory as bin
In Ubuntu, conf is placed in /etc/tomcat7/ and there is a symbolic link in /var/lib/tomcat7/.
To solve this, you can either
Download package from Apache Tomcat, and place them in a specific directory, say /opt/ or
Create a symbolic link in /usr/share/tomcat7/ pointing to /etc/tomcat7/conf

A quick solution in eclipse to resolve when Tomcat could not load as per the following error:
Just refresh the Tomcat folder should do the trick. If it still does not work, delete all files in eclipse under the Tomcat folder, re-copy the server files then refresh the Tomcat folder. Tomcat should restart correctly after that.

I have Windows 8.1, Eclipse Neon, Tomcat 8.
The solution is to copy all the files from folder ".../Tomcatxxx/conf" to the ".../Workspace_directory/Servers" and try to launch server again.

You tried to start Tomcat and got the following error:
Could not load the Tomcat server configuration at /Servers/Tomcat v7.0 Server at localhost-config. The configuration may be corrupt or incomplete
How to solve:
Close Eclipse
Copy all files from TOMCAT_7_HOME/conf to WORKSPACE_FOLDER/Servers/Tomcat v7.0 Server at localhost-config
Start Eclipse
Expand the Servers project, click on the Tomcat 7 project and hit F5
Start Tomcat from Eclipse

I know it's been a while since this question was posted, but I was just getting this exact error, and I have a really simple solution that MIGHT work for some. All I did was double click on the folder 'Servers', which then allowed me to start the server with no error message. Sometimes the solution is right in front of your eyes. This might work for some people like me who go straight to google without trying fix the issue themselves!

on Centos 7, this will do it, for Tomcat 7 :
(my tomcat install dir: opt/apache-tomcat-7.0.79)
mkdir /var/lib/tomcat7
cd /var/lib/tomcat7
sudo ln -s /opt/apache-tomcat-7.0.79/conf conf
mkdir /var/log/tomcat7
cd /var/log/tomcat7
sudo ln -s /opt/apache-tomcat-7.0.79/logs log
not sure the log link is necessary, the configuration is the critical one.

Had the same issue with Kepler (after trying to add a Tomcat 7 server).
Whilst adding the server I opted to install the Tomcat binary using the download/install feature inside Eclipse. I added the server without adding any apps. After the install I tried adding an app and got the error.
I immediately deleted the Tomcat 7 server from Eclipse then repeated the same steps to add Tomcat 7 back in (obviously skipping the download/install step as the binary was downloaded first time around).
After adding Tomcat 7 a second time I tried adding / publishing an app and it worked fine. Didn't bother with any further RCA, it started working and that was good enough for me.

I had the same problem in Eclipse Oxygen with Tomcat 8 in ubuntu 16.04 LTS.
Solution:
1. Give permission to entire tomcat folder (chmod 777 -R /Tomcat)
2. Delete and re-add the server in eclipse
3. Restart eclipse
4. Start the tomcat server. It will work..........

In the Servers tab of eclipse, go to the properties of the server and Switch location to latest downloaded tomcat version.
This resolved the issue for me.
Tomcat Server Properties

I solved this problem. DON'T USE THE .exe
Unistall Tomcat and download the .zip from Tomcat's web site. Then unpack and put it in C:\Program Files. Open Eclipse and set the server. it will work.

Apache Tomcat will not start on Mac

I cannot get Apache Tomcat to start. I followed the instructions for installing Tomcat on the Mac found at https://www.dev2qa.com/how-to-install-tomcat-in-macos/.
After I type the command to start Tomcat, the response from the command line is that Tomcat has started.
However, when I go to the browser, the default page is not showing up. I further checked to see if the port was being used by using the command
lsof -nP -i4TCP:8080 | grep LISTEN
which showed that no program is using the port. I also read the 'RUNNING.txt' that instructed me on setting the environmental variables, which I did. Any suggestions on why Tomcat is not starting up.
I'm using jdk 1.8.0_202 and Apache Tomcat 9.0.14 that is running of Mac OS High Sierra.
BatChmod
After downloading a fresh version of Tomcat, I use the BatChmod app to alter the file permissions. Tomcat will not launch properly without altering the permissions.
I do not know the command-line equivalent, but here is a screenshot of the settings I have used for years successfully.
Plea for help
If anyone can write the equivalent as a shell script for macOS, please post!
Even better, explain how to wrap such a script as an AppleScript for drag-and-drop execution in Finder.
The problem turned out to be a permissions problem. When I installed Tomcat, I put the folder in the '/Library/Tomcat' directory. Even though the Tomcat files were changed to be executable, the user and group ownership remained the same. To get Tomcat to run, I moved the directory to 'Users/MyUserName/Tomcat'. Once I did that, the default Tomcat page ran.

tomcat8 & eclipse mars nightmare

I've tried many different approach for installing a Tomcat server over a Debian jessie distro, for using it as server for an ecplise mars IDE.
The only approach thats works for my debian is to install Tomacat straight from they repo.
And after some little tuning its seems that on localhost:8080 there is what I need (the page that says that tomcat works!).
After that I try to add it on Eclipse with the traditional steps suggested by many tutorial:
-adding xml and web tools support via INSTALL NEW SOFT
-adding the installing path folder to the server etc
Then when I start a new project and i try to add a server trough the "Servers" tab, the wizzard let me to choose the right server/adptor, but then there is some problem.
Instead of this:
I got this:
Where I cant edit the server's name and there a lack of a field, and no hope to hit finish or next. How can I spot where my problem is?
cheers
Don't try to use your installed copy of Tomcat. As has been mentioned in the comments, your normal user lacks ownership of its installed location, and the layout may have been changed by the Debian packaging in ways Eclipse can't predict. Download a tarball from Apache, unpack it, and use that--remember, this is for developing your app, and you should never do that in your production server installation.
You should also check the WTP Tomcat FAQ for other questions you might have.
I found this on ubuntu's forum and with some edit about the version (mine is tomcat 8) works!!!!
Thanks to all that point me in right direction
Here's the way I did it, it keeps the system tomcat and your own
personal tomcat instance separate.
Install tomcat as per normal: sudo apt-get install tomcat7
Install private instance support: sudo apt-get install tomcat7-user
Create local instance in your home folder:
tomcat7-instance-create -p 10080 -c 10005 mytomcat
Note: -p sets the port number (default is 8080) and -c is the control
port (default 8005), we set these so we don't compete with the main
installation of tomcat running as a service. "mytomcat" can be
anything you like, but it will create a directory by this name in your
home.
Now use the following to make Eclipse happy:
cd mytomcat
ln -s /usr/share/tomcat7/lib
ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy
ln -s /usr/share/tomcat7/bin/bootstrap.jar bin/bootstrap.jar
ln -s /usr/share/tomcat7/bin/tomcat-juli.jar bin/tomcat-juli.jar
mkdir -p common/classes;
mkdir -p server/classes;
mkdir -p shared/classes;
Now within Eclipse you can create a Tomcat v7.0 server and set the
installation directory as ~/mytomcat.
Note: common, server and shared classes could be links too, but I
wanted to keep the two separate.

apache tomat7 not starting in browser?

Hi i'm using Apache Tomcat 7,with jdk 1.7 in windows 8. and i have installed tomcat successfully in windows 8,now i'm going hit URL in browser like"localhost:8080" it's work fine,after i open eclipse created web-application & i configured tomcat with that web-application,now i try to restart i'm getting error like!!
so for that,i have stopped tomcat in services(task-manger-service).now it will work fine(it get restarted in eclipse and works fine). when i hit URL in browser like"localhost:8080" i' getting error like ! and more i have added java_home,Catalina_home and also path.
can any one help me out it should work in both eclipse & browser?
First do
netstat -a -b -o
and see if ports that are configured in Eclipse Tomcat are free. If they are not free kill that process
taskkill /PID <pid>
Use /F flag if needed. You should get PID fro, netstat command. You should get Eclipse tomcat ports from Server tab of JavaEE perspective
Then start your tomcat.
PS : If you are getting 404 either you are entering incorrect URL or server is not up in the first place. In any case check the logs if you are getting 404.
Follow the below steps
Right click on your eclipse project
Select Refresh
Click the Run icon
It is not straight forward when you invoke Tomcat from within Eclipse. Please read the FAQ section at https://wiki.eclipse.org/WTP_Tomcat_FAQ
It explains how if you start Tomcat from within Eclipse, the binaries of original directories of Tomcat are used, but the web apps etc are stored separately in the Eclipse Workspace.

How to configure apache tomcat server

I have install jdk1.6.0_04 and I have also install apache-tomcat-8.0.9
and I have set path C:\Program Files (x86)\Java\jdk1.6.0_04\bin;
and CLASSPATH appache tomcat server
C:\Program Files (x86)\apache-tomcat-8.0.9\lib\servlet-api.jar;
but still it's not working properly when i try to open apache tomcat server on web browser
web page is not available
Please guide me the correct way to achieve my objective.
Set JAVA_HOME="C:\Program Files (x86)\Java\jdk1.6.0_04" and CATALINA_HOME="C:\Program Files (x86)\apache-tomcat-8.0.9" than go to %CATALINA_HOME%\bin and run startup.bat
All simple configuration in %CATALINA_HOME%\conf\server.xml
You need jdk1.7 + to run tomcat 8, if you are using jdk1.6, you need tomcat 7-.
See this: http://tomcat.apache.org/whichversion.html
This make me remember back in collage, it took me 2 days to finish jdk/tomcat hello world, :) , what a good time it is.
Just make sure, open a command line, input java --version to check whether you jdk is configured well, and which version it is in use. Just to be sure, in some case you need to re-login or reboot to make your new configured jdk work.
Believe me, if you configured jdk well, you don't need to change anything of the tomcat, just unzip it, and start it, it would work, unless the port 8080 is already taken.
Go to the installation folder of apache tomcat in your case as you said its
C:\Program Files (x86)\apache-tomcat-8.0.9\bin and double click the startup.bat
Then go to web browser and type http://localhost:8080 that should do the work
Set up CATALINE_HOME = your tomcat Location
JAVA_HOME = your java (Version 6 or Seven).
Path = Same JAVA_HOME Java version path til bin.
At final run the startup.bat

Unable to install new relic on linux using tomcat server

I have created account on new relic and downloaded zip for new relic agent and uploaded to /etc directory in my linux machine(tomcat server).
As per documentations, I follow the following code
cd /etc/newrelic
java -jar newrelic.jar install
But I am getting following error:
Dec 31, 2013 06:14:04 +0000 NewRelic 1 INFO: Agent is using Logback
***** ( ( o)) New Relic Java Agent Installer
***** Installing version 3.2.3 ...
Could not edit start script because:
.:. Could not locate a Tomcat, Jetty, JBoss, JBoss7 or Glassfish instance in /etc
Try re-running the install command with the -s <AppServerRootDirectory> option or from <AppServerRootDirectory>/newrelic.
If that doesn't work, locate and edit the start script manually.
No need to create New Relic configuration file because:
.:. A config file already exists: /etc/newrelic/newrelic.yml
***** Install incomplete
***** Next steps:
For help completing the install, see https://newrelic.com/docs/java/new-relic-for-java
Can anyone give me solution for this?
As the log information provide that it Could not locate a Tomcat, you need to provide env var like TOMCAT_HOME and so on.
In linux, even if you have installed some software, it can not be conveniently used without adding into PATH or some other env var.
In your situation, seems you need to add TOMCAT_HOME and export it.
Make sure the tomcat is correctly installed!
I was dealing with the same error, you only need to copy the new-relic.jar file inside the root of your tomcat server and then type:
java -jar new-relic.jar install
And that's it, it worked for me. Hope it helps
I work in support at New Relic, specializing in the Java agent.
Since Tomcat installations vary between Linux environments, your best bet is to follow the manual installation instructions:
https://docs.newrelic.com/docs/java/java-agent-manual-installation
Scroll down to the Tomcat instructions, which advise you to add the -javaagent flag to your Tomcat startup script. Once you've made that change and started your Tomcat instance, you can verify that the newrelic.jar is included in the startup arguments by issuing a ps -ef | grep java command.
If you need further help, please open a support ticket at support.newrelic.com and we'll be glad to assist.
Before installing the New Relic the code will fetch the requisite environment parameters like JAVA_HOME, TOMCAT_HOME, etc ( depends on your configuration) and then install the agent on your server. Make sure all the required env variables are defined.
After you have done the above, also check the following:
a) The New Relic should be extraced/installed in your home directory ( in my case /APP)
cd /APP
Unzip newrelic-java-3.26.1.zip –d /APP
b) The Java agent should be defined in the local properties file ( I have configured it for Hybris server in Dev environment)
vim /APP/hybris/config/local.properties
Add : -javaagent:/APP/newrelic/newrelic.jar –D newrelic.environment=Development
c) In some cases, it requirs the application specific yml file along with the newrelic.yml file ( in my case hybris.yml)
Cd /APP/newrelic
mkdir extensions
chmod 755 extensions
cd /APP/newrelic/extensions
vim hybris.yml
Hybris specific configuration for the hybris.yml file ( use jmx.yml)
Add the jmx.yml data in the hybris.yml after creating the file.
d) Restart your application:
I did it using the following commands:
cd /APP/hybris/bin/platform
ant clean all
e) You should see the data in sometime. Keep monitoring the new relic logs in:
tail -f /APP/newrelic/logs/newrelic_agent.log
Before you do any of these steps, make sure that your new relic folder is in inside the folder of your server. That immediately fixed my problem.
The folder newrelic belongs to /usr/share/tomcat/. At least on Ubuntu 16.04 with Tomcat 7. Then also the install command works. Please do not forget to read and adapt the whole newrelic.yml file.
