I have installed Tomcat 7 in my Ubuntu 12.04. 

Somehow Tomcat is not starting. Tried out all possible steps, checked out forums; nothing helped. 

Can anyone tell me what went wrong?

Log from my PC, for the command:

```
~$ sh  /usr/share/tomcat7/bin/catalina.sh run

```

Thanking in advance.

Reinstalled Tomcat7.
--------------------

This time the missing "server.xml" file is located in path: `/usr/share/tomcat7/skel/conf/server.xml`.

Again tried with:

```
~$ sh  /usr/share/tomcat7/bin/catalina.sh run

```

Logs are below.

Edited from below.
------------------

Forcefully tried to suppress the warnings
-----------------------------------------

Now I have performed the following things:

1. Get bash authentication pass: 

```
~$ sudo bash

```
2. Create a temp directory at /usr/share/tomcat7/skel

```
~# mkdir /usr/share/tomcat7/skel/temp

```
3. Tell Tomcat7 where is my conf/server.xml located

```
~# export CATALINA_BASE=/usr/share/tomcat7/skel

```
4. Run Catalina.sh

```
~# sh  /usr/share/tomcat7/bin/catalina.sh run

```

Logs:

```

Although there are SEVERE message logs present, but when I tested http://localhost:8080 in my browser, I see ***It works!***

**Need experts advice**: should I proceed with my work on Tomcat7 or there are things required to sort out.
