I am running kepler in ubuntu and had the same problem getting eclipse to recognize the tomcat7 server. My path to install directory was fine and deleting/renaming the files only did not fix it either.

This is what worked for me:

run the following in terminal:

<pre><code>cd ~/workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/ 
rm org.eclipse.jst.server.tomcat.core.prefs 
rm org.eclipse.wst.server.core.prefs
cd /usr/share/tomcat7
sudo service tomcat7 stop
sudo update-rc.d tomcat7 disable
sudo ln -s /var/lib/tomcat7/conf conf
sudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy
sudo ln -s /var/log/tomcat7 log
sudo chmod -R 777 /usr/share/tomcat7/conf
sudo ln -s /var/lib/tomcat7/common common
sudo ln -s /var/lib/tomcat7/server server
sudo ln -s /var/lib/tomcat7/shared shared
</code></pre>

restart eclipse, delete tomcat7 server. Re-add server and everything then worked.

Here is the link I used.

I faced the same issue, and I changed the workspace to new location, and it worked.
I hope this helps :)

blocks|key|380817|text|在我的例子中，tomcat目录归root所有，而我没有以root身份运行eclipse。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|380818|所以我不得不|380819|sudo+chown+-R++$USER+apache-tomcat-VERSION/|code-block|syntax|javascript|380820|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

In my case, the tomcat directory was owned by root, and I was not running eclipse as root.

So I had to

<pre><code>sudo chown -R $USER apache-tomcat-VERSION/
</code></pre>

I also had this problem today, and deleting files <code>org.eclipse.jst.server.tomcat.core.prefs</code> and <code>org.eclipse.wst.server.core.prefs</code> didn't work.

Finally I found it's permission issue:

By default <code>&lt;apache-tomcat-version&gt;/conf/*</code> can be read only by owner, after I made it readable for all, it works! So run this command:

<pre><code>chmod a+r &lt;apache-tomcat-version&gt;/conf/*
</code></pre>

Here is the link where I found the root cause:

In Eclipse Neon.3 Release (4.6.3) on Ubuntu 17.04 with Tomcat 8.0 the problem persists. What helped me was the combination of deleting the prefs files:

<pre><code>rm ~/workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.jst.server.tomcat.core.prefs 
rm ~/workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.wst.server.core.prefs
</code></pre>

and linking to <code>catalina.policy</code> (somewhat differently than how @michael-brooks suggested for his configuration):

<pre><code>sudo ln -s /var/lib/tomcat8/policy/catalina.policy conf/catalina.policy
</code></pre>

I was trying to add Tomcat 7 in my Eclipse in Ubuntu. When I click "Add new server" in Eclipse and select "Tomcat v7.0 Server", the field "Server Name" is blank and I cannot type in anything in that textbox as shown below:

<img src="https://i.stack.imgur.com/0pHnn.png" alt="Eclipse Add Tomcat Server">

What I did before is I deleted a Tomcat 7 server from Eclipse and I was trying to reinstall Tomcat 7. But it doesn't allow me to type anything in that textbox and I cannot proceed to the "Next" button. My environment is Ubuntu Linux and Eclipse for JavaEE.
