I've been using the Apache Tomcat Security Handbook and I am
having trouble with using encrypted passwords in tomcat_users.xml

I am running this command straight from the book with some alterations cause I'm in a win2k environment

$ java -classpath %CATALINA_HOME%\server\lib\catalina.jar org.apache.catalina.realm.RealmBase -a sha testpassword

I get the following error message when I try to execute this encryption tool....

Exception in "main" java.lang.NoClassDefFoundError: javax/management/MBeanRegistration

and then a bunch of at java.lang.....stuff.

Why can't I execute this encyption tool and why can't it find the freakin classes. I can run all my jsp pages and servlets just fine in the Tomcat install.

Please help and Thanks if you do!!!!

I am using tomcat 5 and I want to codify password with MD5 using the classes that are in the package to catalina.jar but I obtain the following error:

java -cp catalina.jar org.apache.catalina.loader.WebappLoader -cp catalina.jar org.apache.catalina.realm.RealmBase -a MD5 tomcat
Exception in thread "main" java.lang.NoClassDefFoundError: javax/management/MBeanRegistration

In the classpath already declares the route of the classes of tomcat\server\lib but apparently the classes that are concerned from RealmBase be badly established helpe me please:
