I am using Ubuntu 10.10, using eclipse 3.5. I am developing a web application which needs apache tomcat6. I have downloaded and installed tomcat6.0 using synaptic manager, but eclipse 3.5 says "The Tomcat installation directory is not valid. It is missing expected file or folder lib/jasper-el.jar." though i have browsed through till the installation dir /usr/share/tomcat6.

Please suggest me the solution to install the apache tomcat.

I had the same problem. I am using Ubuntu 10.04, and Eclipse 3.5. I was following this tutorial:

 http://www.vogella.de/articles/EclipseWTP/article.html

I tried to create an apache tomcat6 server using 

 Windows -> Preferences -> Server -> Runtime Environments

but got your error messages. Others had proposed fixes involving changing permissions 

 http://stackoverflow.com/questions/447289/problem-creating-a-tomcat-6-server-

in-eclipse-form-ubuntu

That concerned me. I avoided the permission changes and solved it by doing this stuff.

First: I had installed tomcat6 using ubuntu 10.04 software center. I removed it then installed tomcat6 from a direct download from apache's site 

 http://tomcat.apache.org/download-60.cgi.

I put it into /home/myname/apache-tomcat-6.0.33.

It made it through Windows -> Preferences -> Server -> Runtime Environments just fine.

Second: then doing this:

 Windows -> Show View -> Servers -> Servers

would not list anything at all in the Server window it opened up. After a long time, by chance I right clicked in the Server window which allowed me to do New -> server and select the tomcat6 server

That lists it in the server window, then you can start and stop it through that window.

Third: I also added these lines to the end of /etc/bash.bashrc but I'm not sure whether that was needed. I haven't tried to find out for sure.

JAVA_HOME="/usr/lib/jvm/java-6-openjdk/"

CATALINA_HOME="/home/chuck/apache-tomcat-6.0.33"

export JAVA_HOME

export CATALINA_HOME

PATH=$PATH:$JAVA_HOME

export PATH

The problem is that Eclipse assumes the Tomcat configuration directory resides in the same location with the binary directory. Try this:

cd /usr/share/tomcat6
sudo ln -s /var/lib/tomcat6/conf conf

This should fix it by creating a symbolic link.

Not sure about eclipse 3.5, but in older releases you should configure the path of Tomcat inside Eclipse.

Open the preferences dialog by selecting Window > Preferences, select Tomcat from the left tree menu, and select the correct directories there.
