How reproducible:
1. [pankaj@dhcp Desktop]tomcat-digest  (Use simple cmd with no parameter)

Actual results:

Expected results:
~~~
[pankaj@dhcp Desktop]$ tomcat-digest -a SHA-256 Foo
Foo:1cbec737f863e4922cee63cc2ebbfaafcd1cff8b790d8cfd2e6a5d550b648afa
~~~

Additional info:

- It can be seen that the cause of error is due to the class "org.apache.tomcat.util.ExceptionUtils" is not available for the class loader during this early stage.The class "org.apache.tomcat.util.ExceptionUtils" is located in "/usr/share/tomcat/lib/tomcat-coyote.jar" 

~~~~~~~~~
[pankaj@dhcp233-125 lib]egrep -ir "org.apache.tomcat.util.ExceptionUtils"  /usr/share/tomcat/lib/
O/P : Binary file /usr/share/tomcat/lib/tomcat-coyote.jar matches
~~~~~~~~~

- We also need to add "/usr/share/tomcat/lib/tomcat-util.jar" to classpath or else the cmd will throw the error something like :

~~~
java.lang.NoClassDefFoundError: org/apache/tomcat/util/res/StringManager
	at org.apache.catalina.util.LifecycleBase.<clinit>(LifecycleBase.java:39)
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

	at java.lang.reflect.Method.invoke(Method.java:606)
	at org.apache.catalina.startup.Tool.main(Tool.java:228)
Caused by: java.lang.ClassNotFoundException: org.apache.tomcat.util.res.StringManager
~~~

Workaround : 

- The simple workaround is just add the jar's "tomcat-util.jar" and "tomcat-coyote.jar" to his classpath.

eg :  # CLASSPATH=/usr/share/tomcat/lib/tomcat-util.jar:/usr/share/tomcat/lib/tomcat-coyote.jar tomcat-digest -a md5 mycredentials

- The result would be it includes the missing .jar files needed by tomcat-digest.After adding these jar's the script works as expected.
Comment 2 Michal Karm Babacek 2015-07-07 04:55:01 UTC 
Dear Filip, could you try to reproduce it with our JWS3 RHEL7 RPM and ZIP distro?
Comment 4 Coty Sutherland 2015-11-10 19:56:56 UTC 
The workaround is the fix and matches (mostly) what was done for JWS-232 :)
