Tomcat and Eclipse Integration Error: "Unknown version of Tomcat was specified."
Solution 1
I suggest installing standalone Tomcat into /usr/local
instead of using the one in /usr/share
directory.
cd ~/Downloads
wget http://apache-mirror.rbc.ru/pub/apache/tomcat/tomcat-7/v7.0.52/bin/apache-tomcat-7.0.52.tar.gz
tar -xzf apache-tomcat-7.0.52.tar.gz
sudo mv apache-tomcat7.0.52 /usr/local/apache-tomcat7.0.52
Then use /usr/local/apache-tomcat7.0.52
.
Solution 2
Make sure that the Tomcat folder you're pointing to contains the following files:
conf/catalina.policy
conf/server.xml
conf/web.xml
conf/context.xml
conf/tomcat-users.xml
conf/catalina.policy
conf/catalina.properties
lib/catalina.jar
as Eclipse is scanning for them.
Here is a Linux command which can help you to find that folder:
find /opt /usr '(' -name catalina.policy -o -name tomcat-users.xml -o -name catalina.properties ')' -exec sh -c 'dirname $(dirname {})' ';' | uniq
Solution 3
In Ubuntu the application doesn't have default permission to read/edit all the folders.
I realized that the permissions for the TOMCAT installation directory were not set correctly.
I changed it to 755 and it worked.
sudo chmod -R 755 /opt/tomcat/apache-tomcat-9.0.24/

I am using Ubuntu 13.10 and gnome 3.10.
I have followed this tutorial to set up tomcat and eclipse.:
Set up Eclipse and Tomcat 7 on Ubuntu 12.10 to create Java RESTful Web Services with Jersey
But when I reach step 9, I get the following error on eclipse:
I tried many solutions I saw here on Ask Ubuntu but none worked for me.
I have checked the usr/local folder but tomcat7 is not there.
I checked the
/usr/share
folder and tomcat7 is there.I used the following command to install eclipse and tomcat:
sudo apt-get install eclipse tomcat7 -y

Nemesis over 10 yearsThanks for the quick reply, I updated the text and I have added the /usr/local folder content. as you can see the tomcat is not there but it is located in /usr/share/
-
Nemesis over 10 yearsIt's still the same. I have added a new screenshot.
-
Danatela over 10 yearswhere from did you get this Tomcat?
-
Nemesis over 10 yearsThis is how I installed eclipse and tomcat: sudo apt-get install eclipse tomcat7 -y I have followed the steps in the tutorial.
-
Danatela over 10 yearsOops, I made a mistake. Move
tomcat7
directory back. -
Nemesis over 10 yearsAlready done :)

Nemesis over 10 yearsThanks.. I used sudo apt-get purge tomcat7 to remove the previous tomcat and then I followed your instructions and now it's working like a charm :) Thanks a lot
