Tomcat 6 Error When Deploying War

Question

I have a maven generated war file. When I try and deploy the war file, I am getting the following error in catalina.out:

SEVERE: Exception fixing docBase: {0}

What is this MANIFEST.mf file and why do I need it suddently? I have deployed probably 20 Tomcat applications that work fine without this error occurring and certainly no manifest file.

Answer 1

Check permissions in that directory; I suspect Tomcat can't see META-INF and/or the manifest file.
