Usage

From source file:net.sf.taverna.cagrid.activity.CaGridActivity.java

/**
 * This static block is needed in case some of the caGrid services require
 * https which is more than likely and needs to be executed before we start
 * loading caGrid services or otherwise some of these services will fail.
 * Some caGrid services requiring https have a weird CN in their server
 * certificates - instead of CN=<HOSTNAME> they have CN="host/"+<HOSTNAME>,
 * i.e. string "host/" prepended so we have to tell Java's SSL to accept
 * these hostnames as well. This is not very good at is sets this hostname
 * verifier across all https connections created in the JVM from now on, but
 * solves the problem with such caGrid services.
 * /*from w ww.  j  a v  a 2 s.c  om*/
