Subject Re: unable to get address of epoll functions, pre-2.6 kernel
Date Thu, 29 May 2008 20:51:23 GMT
Hi Emmanuel, 

Good suggestion.  Unfortunately I get the same error - the stack trace line number did change
though so it would seem that I am using the new java version - that's what the ps -ef and
the which java are supposed to show below..  

Any other ideas?

Oh I am using tomcat 6.0.16 if that matters.

$ java -version

$ which java
/usr/local/jdk1.6/bin/java

$ ps -ef
