I have a problem with Tomcat5 on suse.

I installed tomcat just before christmas and was able to access the tomcat
page using http://localhost:8080

However now when I try to access it now I get a message in Firefox "Waiting
for localhost..."

I checked the /svr/www/tomcat5/base/logs/start.log and found the following

Using CATALINA_BASE: /usr/share/tomcat5
Using CATALINA_HOME: /usr/share/tomcat5
Using CATALINA_TMPDIR: /usr/share/tomcat5/temp
Using JAVA_HOME: /usr/lib/jvm/java
/usr/share/tomcat5/bin/catalina.sh: line 284: /var/run/tomcat5.pid:
Permission denied

Can anyone please advise me as to what has gone wrong and how I can fix
