[08:49:12 CST(-0600)] <prabhu> Can you suggest me the steps I should follow to integrate it?
[08:49:33 CST(-0600)] <EricDalquist> well your latest error was java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
[08:49:45 CST(-0600)] <EricDalquist> so I'd guess the portlet is missing the commons-logging jar for some reason
[08:49:59 CST(-0600)] <EricDalquist> so try adding that to the portlet's dependencies and deploying it again
[08:50:08 CST(-0600)] <prabhu> ok
