<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I
am trying to upgrade to the 5.1M2 build from 5.0.1 and am running into some
issues. I have installed the new 5.1 Guvnor and imported the rules from
my 5.0.1 Guvnor instance. <o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I
then removed the old 5.0.1 drools jars from my app and replaced them with the
5.1M2 drools jars. I was also added all the dependent libraries.
The code that worked with the 5.0.1 version does not work with the 5.1M2
version. In 5.0.1 I was constructing the xml and streaming it into the
applyChangeSet method. With 5.1M2 I am just pointing to the change set
xml file that is in the Guvnor. <o:p></o:p></p>
