Tomcat manager throws java exception

[vandora]

Hi everyone,

Can someone please tell me how to solve the error below? My CATALINA_BASE/conf is the original config files
the only thing i had tried to chage was in webapps/manager/WB-INF/web.xml to use FORM based authentication instead of BASIC. But now whenI reverted my changes back, it still does not work


java.lang.NullP ointerException

if this mentioned exception comes in the webpage while accesing your servlet then check your web.xml file also check whether your files are placed under the mentioned directory (Required file for servlet is your java class file).
