Answer 1

In my case, the folder was _Manager. After I renamed it to Manager it worked.

Now, I see login popup and I enter credentials from conf/tomcat-users.xml, It all works fine.

Answer 2

You have to enable access first: Configuring Manager Application Access

Answer 3

After entering the roles and users in tomcat-users still if does not work make sure your tomact server location point to the right server location

Answer 4

I had the situatuion when tomcat manager did not start. I had this exception in my logs/manager.DDD-MM-YY.log:

org.apache.catalina.core.StandardContext filterStart
SEVERE: Exception starting filter CSRF
java.lang.ClassNotFoundException: org.apache.catalina.filters.CsrfPreventionFilter
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        ...

This exception was raised because I used a version of tomcat that hadn't CSRF prevention filter. Tomcat 6.0.24 doesn't have the CSRF prevention filter in it. The first version that has it is the 6.0.30 version (at least. according to the changelog). As a result, Tomcat Manager was uncompatible with version of Tomcat that I used. I've digged description of this issue here: http://blog.techstacks.com/.m/2009/05/tomcat-management-setting-up-tomcat/comments/

Steps to fix it:

1. Check version of tomcat installed by running "sh version.sh" from your tomcat/bin directory
2. Download corresponding version of tomcat
3. Stop tomcat
4. Remove your webapps/manager directory and copy manager application from distributive that you've downloaded.
5. Start tomcat

Now you should be able to access tomcat manager.
