Subject Re: Issue building the Unix daemon (jsvc) with the "configure" script in Tomcat7
Date Fri, 24 Aug 2012 10:01:38 GMT
Fred,

you are getting confused by the term OpenJDK. It comes in two flavor, JRE
and JDK. I have some .h files on my Ubuntu server, but not under
/usr/lib/jvm/java-1.6.0-openjdk but under /usr/lib/jvm/java-6-openjdk

Regards
Jeff

"Legacy code" often differs from its suggested alternative by actually
working and scaling.
