“SEVERE: Error starting static Resources ” in cata

I am getting the following Exception in Catalina.log file when I try to start tomcat 6. I looked for similar queries but could not find a solution mentioned to it.Please note that I have my app inside the tomcat webapp and I am not using eclipse to run it.

Suggestions:

1) Make sure Tomcat isn't inadvertantly deleting your .war. This can happen if something about the .war is "broken":

http://www.coderanch.com/t/479329/Tomcat/disappearing-war-file-tomcat

2) Don't use filenames with spaces.

You can use "dir/x" from a command prompt to see the DOS "8.3" name of any Windows directory:

EXAMPLE: "c:\Program files" likely has the "short name" "C:\PROGRA~1"

3) Edit your descriptors (including app.xml) to substitute the 8.3 name for anything with spaces in it.

4) Unless you're sure Tomcat itself is OK (for example, does the default Tomcat page appear?), then you might just want to consider deleting and reinstalling it.
