javax.management.InstanceAlreadyExistsException: Hibernate:name=statistics

[13年前 に Daniele Poodados によって更新されました。]

Hey,

I'm trying to deploy liferay(6.0.5) as ROOT on an existing tomcat (v6, without any other webapps) ... I did that a several times, but now I always get the following Exception.

As you can see liferay seems to load the property files twice? Is that correct? If not, what could make this happen? I have nothing special here... Just a tomcat, mysql and liferay... Tomcat is not using the default webapps-folder for deploying webapps. But I can't imagine that this could be the reason for this kind of prob...

Thanks for ANY ideas!!

The problem is that something has already registered those Mbeans into the mbean server. Maybe the webapp is initialized twice or something like that.

OK.. I got it. You are right. Tomcat deployed my webapps twice. Now it's working fine.

Thank you!

Hi,

I am also experiencing the same problem. Can you pls tell me what settings you did so that tomcat didn't load it twice?

Thanks

I am having the same problem on tc server (i.e. Tomcat) and I actually just posted about it here in the forum:
http://www.liferay.com/community/forums/-/message_boards/message/14587698

Can you explain how you solved the problem ? I have deployed the WAR only once under webapps/ROOT, and have no idea why it is getting loaded twice.
