Subject Re: ActiveMq console fails with java.lang.ClassNotFoundException: org.apache.jsp.index_jsp
Date Fri, 08 Apr 2011 18:05:35 GMT
FWIW, I've seen this same issue happen several times in the past on 5.4.2
(hasn't happened yet with 5.5.0), but I haven't been able to put my finger
on when/why.  Just wanted to let you know you're not crazy.  The only way
I've worked around it is to restart activemq.
