Null pointer in manager web app. Tomcat 6.0.14

I'm using Tomcat 6.0.14 as part of a cognos product installation. I'm following the installation guide. After installing the product and edit the configuration files, I need to deploy a war and a ear files using de Tomcat Manager application. Trying to log on as the System manager the server returns the following error:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

java.lang.NullPointerException
	org.apache.catalina.manager.HTMLManagerServlet.list(HTMLManagerServlet.java:437)
	org.apache.catalina.manager.HTMLManagerServlet.doGet(HTMLManagerServlet.java:136)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:690)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:803)

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.14 logs.

 

Here is where things get weird, I cannot identify the source of this problem and cannot find the tomcat logs anywhere.

Searching the web I have found some comments about this error but nothing that give a hint of how to correct it:  http://markmail.org/message/3wevmghynlgi3fbh

Please can you help me solve this error ?

question

You need to upgrade your Tomcat version.  Besides the fact that 6.0.14 is incredibly old and missing many security fixes, it appears that this bug has been fixed.

From the link you posted:

">My post is actually a bug report. Not a question.
Those NPEs have been fixed in svn and will be in the next release. "
