Could not load the Tomcat server configuration

Question

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

Solution 1

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

Solution 2

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.

1. Close Eclipse.
2. 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.
3. Launch Eclipse.
4. Go to Window->Show View->Other... and choose the Servers.
5. Select Tomcat v7.0 Server from the server type and press Next.
6. Enter /home/user/tomcat7 (not /usr/share/tomcat7) into the "Tomcat installation directory" and press Download.
7. Wait a few minutes and press Finish.

tomcat7 worked correctly with Eclipse 4.4 on my Ubuntu 15.04 in this way.

Solution 4

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.

Solution 5

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

1. Download package from Apache Tomcat, and place them in a specific directory, say /opt/ or
2. Create a symbolic link in /usr/share/tomcat7/ pointing to /etc/tomcat7/conf

try removing and re-adding the tomcat server to your eclipse environment

[surfealokesea]

Just newly installed Mars and Tomcat thats the solution worked for me

[flixe]

Ok, this still doesn't work for me (tomcat8, eclipse neon, ubuntu 16). When i try to execute sudo ln -s /etc/tomcat8/policy.d/03catalina.policy conf/catalina.policy, it tells me that the file already exists. Eclipse, however, gives me the same error when i try to start tomcat.

[Kalpa Gunarathna]

Yes. I can also confirm that this doesnot work for ubuntu 16.04, eclipse neon and tomcat v8.

[shyam]

@flixe I can confirm that this works on neon.1 on Ubuntu 16.04 and tomcat 8. Did you try removing the server from eclipse and adding it again?

[angeldev]

@shyam works for me as well on neon.1 on Ubuntu 16.04 and tomcat 8

[Ankit]

thanks it worked. In my case the above files were present under Tomcat xx/conf/ ; i copied the files to parent i.e Tomcat xx and as a result I was able to start the inhouse application server.

[Fran Marzoa]

Me too! Thanks!

[RQube]

didn,t worked for me then i tried lucasterdev.altervista.org/wordpress/2012/05/12/… that helped

[Stephan]

This is a very solid solution!

Worked for me with Ubuntu 17.10 and Tomcat 8 (applying the necessary modifications). However, instead of making the configuration files world accessible I added myself to the tomcat8 group using sudo usermod -a -G tomcat8 <myUserId>. After logging off and on again, everything works perfectly.

[Kimchi Man]

Thanks, this saved me haha

My god, so dumb but genius. Thank you for this answer, it was this simple and I totally missed it thinking it was a more complex issue.

this line sudo chmod -R a+rwx /usr/share/tomcat7/conf could be something clever like sudo chmod -R g+rw /usr/share/tomcat7/conf. Then make sure that the owner group is tomcat and that your user is in the tomcat group
