NullPointerException:while upgrading Liferay 5.1 to 5.2

[Manoj Yadav, geändert vor 8 Jahren.]

I am upgrading liferay from 5.1 to 5.2, i did following steps:

Make sure you've got your last complete backup at hand - not just the database backup: e.g. you most likely would like to have your portal-ext.properties available to restore the applicable settings later (The settings most likely will have to be changed, but still: you want to know your customizations to redo them later)
Undeploy the old version of Liferay, and then shut down your application server. For Tomcat, you'd delete the ROOT folder from /webapps.
Copy the new versions of the dependency .jars to a location on your server's classpath, overwriting the ones you already have for the old version of Liferay. For Tomcat, these are stored in /common/lib/ext.
Deploy the new Liferay .war file. This is different by application server. For Tomcat, you'd create a ROOT folder in /webapps and unzip the .war file there.
Delete your tomcat class cache ie /work/Catalina/localhost/ as sometimes tomcat will load class' from the previous version of Liferay instead of the new version
Start (or restart) your application server. Liferay should come up.

After that i am deploying in tomcat 6, we are getting following error:
